Might Ronda Rousey being knocked unconsious be a reference to her recent loss to Holly Holm, where Rousey indeed was knocked unconcious? --[[Special:Contributions/162.158.202.141|162.158.202.141]] 10:27, 11 January 2016 (UTC)
:The word reference means "a thing you say or write that mentions somebody/something else; the act of mentioning somebody/something". Since the comic doesn't mention Holly Holm, there is no reference. I think there isn't even an allusion (something that is said or written that refers to or mentions another person or subject in an indirect way).

:Besides, the phrasing is "knocked out". That needn't be a combat/contact-sport 'KO' in which Rousey was rendered actually unconscious in an intentional/explicable manner, according to the activity, but could just be telling us which of the two passed through to the next round of a bracketed competition of some other kind. (Either of a form that remains unspecified or, as the most recently mentioned competition, in an earlier iteration the hot-dog-eating contest. Either way, 11yo Stewart wasn't highly ''expected'' to win, whatever the match conditions, but the outcome needn't be so against form as it might have in a pugilistic match.)

1626: Judgment Day

2016-01-08T09:42:53Z

162.158.152.227: /* Explanation */ Incorrect pluralisation was just too obvious to ignore. (But at least it wasn't an apostrophised one.)

{{comic
| number = 1626
| date = January 6, 2016
| title = Judgment Day
| image = judgment_day.png
| titletext = It took a lot of booster rockets, but luckily Amazon had recently built thousands of them to bring Amazon Prime same-day delivery to the Moon colony.
}}

==Explanation==
{{w|Terminator_(franchise)#Judgment_Day|Judgement Day}}, from the film ''{{w|Terminator 2: Judgment Day}}'', refers to the day that the {{w|artificial intelligence}} (AI) {{w|Skynet (Terminator)|Skynet}} becomes self-aware and starts a nuclear strike on the United States, Russia, and other regions, killing three billion people. This story has spawned lots of copycats; most stories with this plot have the AI be evil and promptly nuke humanity. This strip could also be an alternate ending for many movies (including the 1970 film Colossus: The Forbin Project).

In this strip, the AI believes that {{w|nuclear weapons}} are not good things to have, and that the amount of them we have now is extreme overkill (17000 held by the U.S.A and Russia alone). Once it's done freaking out, its solution is to shoot the world's nuclear arsenal into the sun. But before it does so it asks the humans: ''What's wrong with you?'' It has thus passed a judgment over humanity. The comic title is thus a pun on the word "{{w|judgment}}" since the computer is being {{w|judgmental}} with humanity and scolding us while correcting our ways, instead of instigating {{w|Last Judgment|Judgment Day}} or any other kind of {{w|Armageddon}}.

As pointed out in the [[what if?]] [http://what-if.xkcd.com/5/ Robot Apocalypse], nuclear weapons aren't any safer for computers than for human beings (the {{w|Nuclear electromagnetic pulse|EMP}} would destroy circuits), so an AI would want them gone as quickly as possible.

{{w|North Korea}} claimed to have [http://www.bbc.com/news/world-asia-35240012 successfully tested] its first {{w|hydrogen bomb}} in the evening on the day before this comic was published; at about 8:30 PM in {{w|Massachusetts}} where [[Randall]] lives. (At that time it was already 10:00 AM on the day of the comics release in {{w|Pyongyang}} the capital of North Korea, but that was still several hours before this comic were released). This comic could thus be Randall's response to the ongoing {{w|nuclear arms race}}.

Even the most powerful of nuclear weapon launchers, {{w|intercontinental ballistic missile}}s, are not designed to make anything other than {{w|sub-orbital}} flights and could not fly to the Sun (which is actually surprisingly difficult, even with the soon-to-be-mentioned extra boosters, since the rocket would have enough {{w|delta-v}} to bleed off the {{w|orbital speed}} of the Earth around the Sun -- it is likely that the sentient AI is using the same strategy of the Solar Probe Plus and planning several flybys of Venus to do that work). The title text rationalizes that the capability to do so may perhaps be granted by the use of an {{w|Amazon.com|Amazon}} resource that might have also been developed by the time of this instance of computer sentience, aided (if not initiated!) by the fact that Amazon's whole business infrastructure is already highly computerized and could ''at the very least'' be complicit with the process of delivering and then controlling the rocket-power, without any conscious human intervention. As there is already an extended colony on the Moon, it will for sure take many years before we reach this future scenario.

"A lot of booster rockets" is likely to be a reference to the spaceflight simulator game {{w|Kerbal Space Program}}, which Randall has [[1106|referenced]] on a [[1244|number]] of [[1356|occasions]]. In the culture of that game, any launch failure can be resolved by [https://imgur.com/20aIBMW "adding more boosters"] to the spaceship design.

It is the second time in a few months that the speed of Amazon's deliveries has been the subject of a joke, the last time was [[1599: Water Delivery]], where it was the one hour delivery that was the subject of the joke. It is also the second title text in a row (after [[1625: Substitutions 2]]) where Amazon has been mentioned.

This particular 'machine take-over' future is in distinct contrast to the possible future directions given in [[1613: The Three Laws of Robotics]], but this comic likely depicts spontaneous ''self-''sentience, not a system with deliberately imposed human 'values' and possibly no actual conscience or even consciousness of its own. Other problems with hostile AI take over is presented when it fails completely in [[1046: Skynet]]. Also it is not all AI that wish to interact with us at all as shown in [[1450: AI-Box Experiment]]. These are just a few of the many [[:Category:Artificial Intelligence|comics about AI]] in {{xkcd}}.

Adding a second layer to the humor, the machine's reaction could also be read as the reaction of someone who has moved in with someone else, discovered a collection they find distasteful, and is now changing things to fit their preferences. "My my God, why do you even have all of these [tschotskes, ratty tee shirts, porn magazines, handcuffs, dildos, slime-mold samples]" Upon obtaining sentience, the machine is the new roommate of the human race and is expressing its disgust at one of our dirtier habits.

I feel old because all of those things mentioned (even the 20-year ones) are so much more recent than my own personal milestones and I know that the unsaid 30-year set, at least, would be even better.

Let's see, a sample list for 30 years could include, as one per month: The ''Challenger'' disaster; Halley's Comet; Microsoft's IPO; Chernobyl; ''Short Circuit''; Mexico hosts the World Cup; Prince Andrew marries Sarah Ferguson; ''Castle In The Sky'' from Studio Gibhli; Desmond Tutu is a Bishop; Reagan and Gorbachev meet (unsuccessfully) in Reykjavík; Iran-Contra; Rutan Voyager's non-stop non-refuelled circumnavigation of the Earth; and, precise date unknown... The Simpsons created!

And 40 years has its interesting points: the Cray-1 created; Apple Computers formed; Concorde flies; as does the (shuttle prototype) Enterprise; Vikings 1 and 2 land; Jimmy Carter nominated; Bob Marley killed; the Sex Pistols swear; the first Laser Printer; ''The Selfish Gene''...

Anyway... Happy New Year, to all. Young ''and'' old. [[Special:Contributions/162.158.152.227|162.158.152.227]] 20:10, 1 January 2016 (UTC)

In response to the title text, "You know, it's such a beautiful day that I think I'll walk." See https://en.wikipedia.org/wiki/It's_Such_a_Beautiful_Day. [[Special:Contributions/198.41.238.32|198.41.238.32]] 07:23, 30 December 2015 (UTC)

A number of "inventions" from various science fiction stories of the late nineteenth and the twentieth centuries are listed with how they have progressed in the present. Some are currently being used (flying car) but in a different manner than originally imagined (helicopters, which use rotating blades rather than stationary airfoils -- wings -- for lift). Some are impractical for physical reasons (floating sky city) and some have economic (moon colony) or social impediments (jetpack). The entry for "hoverboard" and the title text refer to two different kinds: the science fiction version in "Back to the Future" is a skateboard with some form of levitation instead of wheels, while the current version is a short skateboard that has more freedom of motion but less stable balance than a conventional skateboard.

There are two possibilities for "robot butler": either it refers to the "ask Jeeves" search engine or implies that P. G. Wodehouse's "perfect gentleman's gentleman" was a robot. [[User:The Dining Logician|The Dining Logician]] ([[User talk:The Dining Logician|talk]]) 08:36, 30 December 2015 (UTC)

Jeeves is also the name of a "robot butler" in World of Warcraft. Although it's a pretty convenient item even if it's 4 years old, it's not that great compared to what you would expect from a true "robot butler". Jeeves merely allows you to repair your equipment or access your bank, both of which are really easy to do anyway.

{{incomplete|Open to editing, but perhaps a useful start.}}
As each year turns (or other milestone dates, perhaps set out in popular fiction) it is common enough to remember that what is now the present was once considered ''the future!''

This comic, published just prior to the start of 2016, aims to clarify a number of the things one might have expected by now.

The classic target of personal futurology is the ability to levitate or fly, to varying degrees. "Where's my {{w|jetpack}}?" is one of the [http://tvtropes.org/pmwiki/pmwiki.php/Main/IWantMyJetPack memes] addressed here, and has actually been developed in a somewhat workable fashions and {{w|Astronaut propulsion unit|analogues}}, but is dismissed as being too personally dangerous to have a {{w|The_Jetsons|Jetson}}-like ubiquity. Similarly, various forms of {{w|Flying_car_(aircraft)|flying car}} have had varying {{w|AVE_Mizar|degrees}} of {{w|Moller_M400_Skycar|success}}, but here are ignored to point out that the regular {{w|helicopter}} is as close as most of us would ever get to this technology. The {{w|Hoverboard|levitating Hoverboard}} has been popularised by the {{w|Back_to_the_Future_Part_II|Back To The Future franchise}} of films, with several attempts to fully emulate such a device with air-blast or magnetic levitation, but the ''term'' Hoverboard has ended up being applied to a {{w|Segway}}-like {{w|Self-balancing_two-wheeled_board|personal transport system}} that has at least become a mass-produced device (albeit with a number of {{w|Self-balancing_two-wheeled_board#Safety|safety concerns}}).

(The very concept of the hoverboard, in particular, is predicted to be reduced mostly to arguments between opposing camps of opinions; and then, in the title-text, the conclusion that giving up and resorting to old-fashioned walking is inferior to ''any'' of the possible alternatives...)

A much bigger challenge in levitation is the 'sky city', with various forms {{w|Bespin|from}} {{w|Mortal_Engines_Quartet|fiction}}. In reality, this seems highly unlikely to ever come to pass when there is perfectly good ground to lay the buildings down upon, due to the sheer mass. (But never say never!) It might be considered more reasonable to build a {{w|Space:_1999|settlement of some kind}} on the Moon. The basic {{w|Apollo_program|engineering}} {{w|International Space Station|exists}}, but the comic blames financial pressures for it not yet having come into existence. (Arguably political pressures, or perhaps the lack of them, are also a factor.)

From the fields of automation, the {{w|Autonomous car|self-driving car}} has had a lot of recent development put into it, with many and varied protypes being tried out, and may actually end up featuring in our immediate future, even if not in 2016. Meanwhile the long-held science-fantasy aim to create a {{w|Robby the Robot|robot that can do odd tasks}} has been {{w|Roomba|limited}} or a {{w|Ask.com|differently implemented}} and the ''fully'' omnicapable version is probably almost as far out of reach as it always was considered to be.

As each year turns (or other milestone dates, perhaps set out in popular fiction) it is common enough to remember that what is now the present was once considered ''the future!''

This comic, published just prior to the start of 2016, aims to clarify a number of the things one might have expected by now.

The classic target of personal futurology is the ability to levitate or fly, to varying degrees. "Where's my jetpack?" is one of the memes addressed here, and has actually long ago been developed in a somewhat workable fashion, but is dismissed as being too personally dangerous to have a Jetson-like ubiquity. Similarly, various forms of flying car have had varying degrees of success, but here are ignored to point out that the regular helicopter is as close as most of us would ever get to this technology. The levitating Hoverboard has been popularised by the Back To The Future franchise of films, with several attempts to fully emulate such a device, but the ''term'' Hoverboard has ended up being applied to a Segway-like personal transport system that has at least become a mass-produced device (albeit with a number of safety concerns).

A much bigger challenge in levitation is the 'sky city', with various forms from fiction. In reality, this seems highly unlikely to ever come to pass when there is perfectly good ground to lay the buildings down upon, due to the sheer mass. (But never say never!) It might be considered more reasonable to build a settlement on the Moon. The basic engineering exists, but the comic blames financial pressures for it not yet having come into existence. (Arguably political pressures, or perhaps the lack of them, are also a factor.

From the fields of automation, the self-driving car has had a lot of recent development put into it, with many and varied protypes being tried out, and may actually end up featuring in our immediate future, even if not in 2016. Meanwhile the long-held science-fantasy aim to create a robot that can do odd tasks has been limited or differently implemented and the ''fully'' omnicapable version is probably almost as far out of reach as it always was considered to be.

This "catch the sun in the butterfly net" subplot reminds me of novel by Polish author Kornel Makuszyński (and a children's films based on it) "{{w|The Two Who Stole the Moon}}" --[[User:JakubNarebski|JakubNarebski]] ([[User talk:JakubNarebski|talk]]) 08:43, 28 December 2015 (UTC)

I had to laugh at this part of the explanation, and then remove it: "(In reality, the fact that the net is not melting or burning proves that the sun is nowhere near the net.)" Because in this comic they obviously catch the sun ion a net, as they later (after the catch) has put it on sale on Craiglist as per the title text. But the reason I laughed was that the only problem the writer of this sentence saw was that the sun would be too hot. What about it's size and gravity, if we are talking about the real sun... So yes if it where the real sun it would be a long way away to look this small (150 million km as usual, 8 light minutes). But in this comic it is between the trees and it is very small and cool. Only strange thing is that [[Beret Guy]] is not involved as his [[:Category:Strange powers of Beret Guy|powers]] would explain this comic. But then again he would never do it for profit. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:23, 28 December 2015 (UTC)
:I disagree, there's no indication that this scheme actually worked. The Craigslist posting could just as easily have been written in advance, and the Title text could be the next line spoken, before the capture either succeeds or fails. [[User:Swordsmith|Swordsmith]] ([[User talk:Swordsmith|talk]]) 16:48, 28 December 2015 (UTC)

The "sun exposure" explanation is wrong. It's not about how it holds up under sunlight, it's about how much sunlight it gets. [[Special:Contributions/198.41.235.101|198.41.235.101]] 17:21, 28 December 2015 (UTC)

The phrase "any given day" suggests that the two hypothetical trees will align with the sun on any day of the year arbitrarily chosen. A better way to say it would be "...Cueball realizes that the setting sun would line up with almost any two trees on at least one day of the year." (Anonymous user Ben) [[Special:Contributions/108.162.214.239|108.162.214.239]] 16:43, 29 December 2015 (UTC)
:If the observer is able to move freely, he can always position himself in such a way that the sun will set between the two trees on any give day. The only exception will be if the two trees and the sunset are aligned, i.e. the trees obscure the sun. [[User:Sysin|Sysin]] ([[User talk:Sysin|talk]]) 17:24, 29 December 2015 (UTC)

The line about "getting rich" got me thinking.... Only 5E-10 of the sun is gold [http://answers.google.com/answers/threadview?id=224308] but the sun's mass is approx 2E30kg [http://www.google.com/webhp?q=mass%20of%20sun], so that's 1E21 kg of gold (about US $35 septillion at today's prices), and that's just one element, there are all sorts of precious metals in the sun's core... [[User:Sysin|Sysin]] ([[User talk:Sysin|talk]]) 17:19, 29 December 2015 (UTC)
: ^^(about US $35 septillion at today's prices)^^ - yes, but, once you had it (in a lump it'd be over 1% the mass of the Moon or perhaps 300 billion Mt Everests) in your posession and started to sell it, not anywhere near so much at ''tomorrow's'' prices... ;) [[Special:Contributions/162.158.152.227|162.158.152.227]] 12:48, 30 December 2015 (UTC)

The selling of Sun on craigslist is possibly a refernce to the woman who was selling land on the sun on ebay -- http://www.dailymail.co.uk/news/article-3112111/What-blazes-Spanish-woman-selling-plots-land-sun-1-sues-eBay-breach-contract-auction-site-closes-down.html [[Special:Contributions/162.158.255.46|162.158.255.46]] 17:30, 29 December 2015 (UTC)

}}

==Explanation==
The second [[:Category:Christmas|Christmas comic]] in a row, the first being [[1620: Christmas Settings]].

This comic was released on {{w|Christmas}} day as a present from [[Randall]] to all {{w|physicists}}. It introduces a new particle, the ''Fixion'', which explains everything. The word "Fixion" can be read as a pun: Either it can mean something like "fix-i-on," with "[https://en.wiktionary.org/wiki/-on#Suffix -on]" being a suffix for many particles, and this particle being able to "fix" things; or it means "fiction" (in English, the pronunciations of "-xion" and "-ction" are indistinguishable). Alternately, "Fixion" could be a portmanteau of "fix" and "ion", implying that the particle is not subatomic but is a different type of ion.

In physics, there are still many {{w|List of unsolved problems in physics|big questions and mysteries}}. There are many phenomena which don't seem to fit, and we don't know how to explain yet. The "Fixion" is satirically presented as a particle which acts as a {{w|Deus ex machina}}, (see also [http://tvtropes.org/pmwiki/pmwiki.php/Main/DeusExMachina tvtropes]), which solves all of these mysteries without any serious fundamental reasons.

The style of the chart suggests a {{w|Feynman diagram}} - an easy way of drawing particle interactions. Every time there is an interaction, the main central Fixion-line changes direction. Typically, {{w|fermions}} (the "solid" particles like {{w|electrons}} and {{w|quarks}}) are shown with solid lines, {{w|photons}} (and generally the weak-force-carrying {{w|bosons}}) are shown with wavy lines, {{w|gluons}} with spiraling lines and other mediating particles (such as {{w|pions}} in the {{w|nuclear force}}, or the {{w|Higgs boson}}) with a dotted line. Randall obeys these rules only very loosely, which makes sense - many of the things involved in this Feynman diagram are either so theoretical that they have no widely used standard representation, or would never appear in a sensible diagram (spacecrafts, for instance). All mentioned types of lines - and even more types - are presented in the diagram. All that the Fixion does is described in the [[#Table of Phenomena|table below]].

The title text is a continuation of one of the jokes already mentioned in the main comic (fourth phrase from the top to the left) about {{w|Fast radio burst}}s (FRBs) and {{w|Peryton (astronomy)|perytons}}. See explanation in the last entry in the [[#Table of Phenomena|table below]].

{| border =1 width=100% cellpadding=5 class="wikitable"
|'''Phenomenon''' || '''In the comic''' || '''Description''' || '''Solved?'''
|-
| Main component of dark matter
|| An arrow points to the very first part of the main line.
|| Our best measurements of the universe predict that visible matter is only about one-sixth of the matter in the universe; the remaining matter is "{{w|dark matter}}" that cannot be seen. The leading candidates for dark matter are {{w|weakly interacting massive particles}} (WIMPs). These would be new, undiscovered forms of matter which barely interact except through gravity and thus give off little or no light. Some of the dark matter is likely made up of {{w|Massive compact halo objects}} (MACHOs); effectively dead stars too dim to see. MACHOs are probably only a minority of the dark matter, however. Studies of two colliding galaxy clusters suggest that dark matter can pass through other matter without slowing down, unlike ordinary matter. Moreover, calculations of the elements produced during the {{w|big bang}} - which match the observed distribution of elements in the universe very precisely - don't leave room for enough additional {{w|protons}} and {{w|neutrons}} to form the dark matter.
|| No. Proving the nature of dark matter will most likely win someone a {{w|Nobel Prize}}.
|-
| Confines quarks and gluons
|| An arrow points to the very first part of the main line.
|| {{w|Quark confinement}} means that we never see particles with {{w|colour charge|color charge}} (i.e. {{w|quark}}s and {{w|gluon}}s) on their own. They only exist in groups that cancel out the color charge. Try to separate the groups, and the energy you add will instead cause new particles to pop into existence.
|| The basic facts of confinement are well understood, but some of the details are too complicated to tease out.
|-
| Neutralizes monopoles
|| An arrow points to the first solid line into the main line, from left and upwards. This is thus a solid particle merging with the Fixion.
|| {{w|Magnetic monopoles}} (e.g., a north charge without a south charge) should exist, according to many {{w|Grand Unified Theory|grand unified theories}} (GUTs) and {{w|String theory|string theories}}, but none have ever been seen.
|| No! Despite claims that pop up in the news every year, creating a monopole-like state in the magnetic spins of a crystal is not the same as creating a real monopole.
|-
| Suppresses antimatter in early universe
|| No arrow.
|| The universe today is made almost entirely of matter. {{w|Antimatter}} and matter are identical, except that the charges are opposite. Antimatter and matter "{{w|Annihilation|annihilate}}" when they come into contact? So why is the universe made of matter? Why didn't the universe have equal amounts of both, and if it did, why didn't it annihilate itself immediately? This is a big question in physics today. Of course, the Fixion explains this by its ability to suppress the formation of antimatter in the early universe.
|| Lots of theories, no conclusive evidence for any yet. The most notable theories revolve around the {{w|weak interaction}}, which has been shown to treat matter and antimatter asymmetrically. Now that the {{w|Higgs boson}} has been found, the biggest project for the {{w|Large Hadron Collider}} experiments is to try to crack this.
|-
| Spontaneously emits dark energy
|| Two arrows points to two dotted lines going out left and downwards below the first solid line. It is thus two mediating particles that go out from the Fixon.
|| Prior to the 1990s, most {{w|cosmologists}} expected that the universe's expansion after the Big Bang would either slow down or stay constant. In 1998, cosmologists discovered that the expansion of the Universe is accelerating. Under {{w|Einstein|Einstein's}} theory of {{w|general relativity}}, the observed acceleration predicts that ordinary matter and dark matter make up about 30% of the universe's total energy, with the rest coming in the form of "{{w|dark energy}}." The nature of dark energy is not certain. However, the leading candidate is that space itself has intrinsic energy (either constant or variable), and so as space expands, the energy of the universe increases.
|| Again, Nobel Prize territory.
|-
| Mediates proton decay, but then hides it.
|| An arrow point to several lines going to and from the main line. The outer line does not connect with the main line. Maybe this represents the hiding part of this proton decay mediator.
|| Many GUTs predict that {{w|proton decay|protons will decay}}, but experiments have shown the proton to have a half-life of at least 1033 years very much longer than the {{w|age of the universe}} (1.38x1010 years).
|| It's not ''necessarily'' a problem. All theories predict that proton decay is a very slow process (1032+ seconds), which is consistent with the current data.
|-
| Introduces dispersion in perytons from kitchen microwaves, explaining fast radio bursts
|| Two arrows point to four wavy lines. The waves of the lines have different wave length. The one line coming out left is of the same at wavelength as the top of the three coming out right. The two below each decrease in wavelength compared to the one before them. Maybe this is not meant to represent photon-like particles, but are just different frequencies of microwaves from the microwave oven – thus relating to the subject.
|| {{w|Fast radio burst}}s (FRBs) are unexplained bursts of radio-frequency energy from space, they could even be extragalactic signals, with speculations that they might be signs of {{w|extraterrestrial intelligence}}. {{w|Peryton (astronomy)|Perytons}} are things that ''look like'' FRBs, but come from Earth (specifically, from the {{w|microwave oven}} at {{w|Parkes Observatory}}). Randall's Fixion makes some perytons change frequency distribution so they appear to come from space; thus in fact all FRBs come from microwave ovens.
|| No, but it's probably something very big - a star collapsing to a {{w|black hole}} or (as now looks likely) a {{w|magnetar}} (magnetic neutron star)
|-
| Broken symmetry causes ϴ=0, explaining unobserved neutron dipole moment
|| An arrow points to the part of the main line just before the first wavy line.
|| The {{w|neutron electric dipole moment}} is a measure of how balanced electric charge is inside the neutron. ϴ (theta) is a number in {{w|quantum chromodynamics}} (QCD) which quantifies the breaking of a type of symmetry called {{w|CP violation|CP symmetry}}. If ϴ is not 0, one result of this should be a neutron dipole moment. {{w|Symmetry breaking}} is a common explanation of effects in some areas of theoretical physics (for instance, it's an important part of {{w|Peter Higgs|Higgs'}} theory about why particles have mass), but normally it explains why a value is ''not'' zero. Presumably the Fixion breaks CP symmetry independently of QCD, which means that ϴ can be 0 while preserving observed CP-breaking effects.
|| Again, it's not (yet) a problem - the predicted dipole moment is tiny, and we're only just reaching the point when we can measure it that accurately.
|-
| Causes alpha effect
|| No arrow.
|| Ther {{w|alpha effect}} is a weird effect from chemistry, where putting an "alpha" atom with a {{w|lone pair}} of electrons close to a molecule makes the molecule more likely to give up its electrons. The Fixion is the reason for this effect.
|| Lots of competing explanations.
|-
| Covers naked singularities
|| No arrow – but the text is situated next to the middle of the three wavy lines going right.
|| A {{w|naked singularity}} is like a black hole without an {{w|event horizon}}. So far no naked singularity has been observed (except, arguably, the big bang) and the {{w|cosmic censorship hypothesis}} suggests they can't exist, although some people have suggested ways of making them. Of course if any did exist then the Fixion will cover it, so it won’t become embarrassed by its nudity. Randall has mentioned these in his latest [[what if?]]: [http://what-if.xkcd.com/140/ Proton Earth, Electron Moon].
|| Not necessarily something that needs explaining - none have been seen, and most theories say they don't exist. If support grows for {{w|loop quantum gravity}}, then we might have to start really searching.
|-
| Intercepts certain gravitational waves before they're observed.
|| An arrow points to a spiraling line going upwards to the left, so this is drawn like a gluon.
|| If {{w|gravity}} behaves like {{w|Fundamental interaction|the other forces}}, it must be conveyed by waves. Our best detector, {{w|LIGO}} has yet to detect any {{w|gravitational waves}}, though this is probably just due to the low probability of events that would be detectable. Only extreme events like {{w|binary black hole}} mergers are detectable with the current setup. The proposed {{w|LISA Pathfinder}} spacecraft will be able to see things like orbiting black holes and {{w|neutron stars}}. Since the Fixion intercepts gravity waves before they are observed we should not get our hopes up too high about observing any even with LISA.
|| Let's wait for the LISA data before jumping to conclusions.
|-
| Causes coronal heating
|| No arrow – but the text is situated next to the middle of the three wavy lines going right.
|| For some reason the outer layer of the {{w|sun}} (the {{w|corona}}) is hotter than most reasonable theories predict. This is for instance mentioned in Randall’s new book ''[[Thing Explainer]]'' in the entry about the sun. This can also be seen on the [[Thing_Explainer#Preview Pages |back cover of the book]]. The phenomenon is explained by the Fixion…
|| It's a mystery, but it possibly has something to do with waves in the corona (for example, the {{w|High Resolution Coronal Imager}} has seen "braids" in the corona that whip around and unravel themselves).
|-
| Higgs-ish
|| As this is just a property of the Fixion there is no arrow.
|| The {{w|Higgs boson}} is a manifestation of the Higgs field... but many supersymmetry and string theories predict multiple Higgs-like particles. It's almost a prerequisite of any new theory that it has a Higgs-ish element. So the Fixion blends in with this.
|| N/A
|-
| Superluminally smooths anisotropies in early universe (but adds faint polarization for BICEP3 to find)
|| An arrow points to the point of the main line just below the bottom space probe.
|| The {{w|Cosmic Microwave Background}} (CMB) is incredibly uniform. In fact it is so uniform that the conclusion is that these areas must have been in contact at some time in the early universe. But with the universe being infinite, and the speed of light being finite, most parts of the universe will never be able to interact (any more at least). The explanation usually given for the uniformity is that the universe expanded really fast in the beginning during what is called the {{w|Inflationary epoch}}. {{w|BICEP_and_Keck_Array#BICEP2|BICEP2}} is a {{w|radio telescope}} at the South Pole whose operators claim to have seen polarization in the CMB indicative of inflation. (See [[1365: Inflation]] that references BICEP2's results). The Fixion fixes the problem since it allowed {{w|Faster-than-light|superluminally}} smoothing of the early anisotropies to explain the smoothness observed today. The Fixion adds just enough signal that the new {{w|BICEP_and_Keck_Array#BICEP3|BICEP3}} telescope will be able to find it.
|| As stated, {{w|Inflation (cosmology)|inflation}} is the standard explanation and it holds up fairly well. Other studies haven't seen the polarization that BICEP2 has - the {{w|Planck (spacecraft)|Planck space telescope}} also suggests that the BICEP2 team were looking at an unusually dusty bit of space, which could cause polarization. Hopefully this will improve with the BICEP3 data that should be published in 2016.
|-
| Accelerates certain spacecraft during flybys
|| Two arrows point to two solid lines going away from the main line (left and right). At the end of each line there is a space craft with satellite dish and solar panels, representing the items that the Fixion interacts with.
|| This refers to the {{w|flyby anomaly}} which is sometimes (but not always) seen when spacecraft fly close to planets and pick up more speed than expected. It's not always seen – for instance the {{w|Rosetta (spacecraft)|Rosetta space probe}} had no flyby anomaly when it swooped extremely close to Mars. Another anomaly for spacecraft’s (a deceleration this time) has been mentioned in the title text of [[502: Dark Flow]].
|| It could be an unpredicted quirk of gravity and relativity... or it could be experimental error.
|-
| Triggers Siberian sinkholes
|| No arrow, but it is right next to the solid line with an arrow going into the main line just before the first hole where the main line disappears and becomes dotted. Thus it could be a reference also to these holes.
|| Recently, (2014), several {{w|sinkholes}} opened up in {{w|Yamal_Peninsula#Yamal_craters |remote parts}} of Siberia. The explanation is currently unknown, except of course we now know that it was the Fixion that caused it.
|| While there are lots of weird theories, there's a good chance they were caused by {{w|Arctic methane release}} due to melting {{w|permafrost}} which is probably caused by {{w|global warming}}. See ([http://www.independent.co.uk/news/science/mystery-of-the-siberian-holes-at-the-end-of-the-world-solved-scientists-offer-explanation-9642988.html Mystery of the Siberian holes… solved]).
|-
| Melts ice in "Snowball Earth" scenario
|| No arrow.
|| {{w|Snowball Earth}} is the theory that the whole planet was covered in ice at some point. To melt all that ice by the {{w|greenhouse effect}} would require far more carbon dioxide in the atmosphere than seems plausible. However, if volcanoes were to deposit black soot on the surface of the ice, it would start absorbing heat more efficiently (in scientific terms, the Earth's {{w|albedo}} would decrease) and that would also make the planet heat up. Of course it was the Fixion was the cause of the melting ice.
|| There are {{w|Snowball_Earth#Scientific_dispute|scientific dispute}} regarding the theory for a Snowball Earth. There is no conclusive evidence that it ever occurred, but those in favor have presented lots of {{w|Snowball_Earth#Evidence|evidence}}…
|-
| Transports neutrinos faster than light, but only on certain days through one area of France
|| An arrow points to the part of the main line that becomes dotted between the two “{{w|wormholes}}”. This is where the neutrinos move faster than light…
|| Refers to the {{w|faster-than-light neutrino anomaly}}, where it seemed that a neutrino beam from {{w|CERN}} on the France/Switzerland border to the {{w|OPERA experiment}} in Italy traveled faster than light. Scientists were not able to reproduce the result. Of course it was because of the Fixion. This Neutrino experiment was also mentioned in [[955: Neutrinos]], where there are more explanation on the subject.
|| In the end, there was no mystery, just a [http://www.redorbit.com/news/science/1112551696/cern-confirms-neutrinos-not-faster-than-light/ defective cable causing a measurement error].
|-
| Suppresses sigma in experiments
|| No arrow but the last solid line, with an arrow pointing left, that is going away from the main line, point almost directly at it.
|| Sigma (σ) refers to the {{w|standard deviation}} - a mathematical measure of how much an observed value differs from the expected value. For a formal scientific discovery in particle physics, the standard is 5 sigma which means that there is about a 1 in 3.5 million chance that the results were caused by random errors (of course, they could be caused by ''systematic'' errors, such as measurement problems). Some tantalizing experiments have found interesting results at 3 or 4 sigma but either can't reach 5 sigma or {{w|Oops-Leon|are subsequently dis-proven}}. The question is, if the way the Fixion works here in this comic pushes the sigma value one way or the other? Does it suppress the value so it goes below or above the level of significance? Is it artificially pushed in the direction so a result seems like it is significant when it is not (see for instance [[882: Significant]]), or if it is the other way so some experiments, which could have found what the experimenters wanted to find, did not because the sigma has been artificially lowered below the proof threshold. Either way it is a very annoying fact of the Fixion, but it would explain a lot, and probably also make it very hard to find the Fixion because of this intrinsic behavior.|| N/A
|-
| My theory predicts that, at high enough energies, FRBs and perytons become indistinguishable because the detector burns out.
|| From the title text.
|| This is a continuation of the joke already mentioned above regarding Fast radio bursts (FRBs) and perytons. GUTs normally predict that all the forces we see are the different low-energy versions of a single force which can only be seen at extremely high energies (much higher than any Earth-based collider could produce). A high-energy FRB would be a {{w|gamma ray burst}} and if it came from a close enough object, would obliterate all life on Earth... It would also wreck the sensitive electronics at Parkes Observatory. This "high energy unification" is stated in a way reminiscent of the unification of electromagnetic and weak forces at high energies; but unlike the latter, it involves two things only "appearing" (or, in this case, not appearing) to be the same, not actually becoming the same.

:The '''Fixion'''
:A new particle that explains everything

:[A chart resembling a Feynman diagram is shown. It begins with a solid line coming down at the top, going a little to the left. The line continues downwards all the time, but changes direction 16 times before exiting at the bottom almost straight under the starting point. At every point where it changes direction, there is some kind of “interaction” with something outside this line. There are 19 phrases, 10 on the left and 9 on the right. 11 of these are distinct labels for points on the line as 14 gray curved arrows points between these 11 phrases to specific points on the line. Three of the phrases on the left has two arrows pointing to two different, but close, parts of the line. The main central line is solid all the way, except at the very bottom, where it “disappears” inside a hole only to “reappear” later from a similar hole. Between these two holes the line is dotted. The lines going away (or to) the main line can be straight and solid, straight and dotted, wavy lines (with different waviness), even looking like a spiral. Two straight solid lines ends up at two space probes, and finally the last two straight solid lines coming in (and out) on either side of the “hole” in the line has arrow pointing in and out. Below the phrases will be listed in reading order, taking one on each side alternatingly. Above each is described if there are any arrow and, if there are, what they points at.]

It bends closer to the other lines in the middle. The next line is connected to the main line, and is thus actually two lines going in to the main line. The same goes for the inner line, where there is some distance between the entry and exit, as the middle of these three lines connect to the main line in between. In principle there are four lines going in/out and one not connected, but it looks like three lines:]
::Mediates proton decay but then hides it

A second arrow points further down the main line where there are three more wavy lines coming out, but to the right, they are all of the same length and go almost straight right, only a little down. The first has as short a wave length as the line above to the left, but as it is shorter it only has 6 peaks. Then the wavelength decreases to a very long one for the last, 5 peaks and then 3 peaks.

Probably could do with a table of the options and associations. Better than the following that I just drew up (and actually formatted as a table!):
:Chimney - traditional (but not always practical) to our universe; also usable (to varying degrees of success) by Big Bad Wolves, adventurous burglars and adverse atmospheric/weather conditions;
:Shower Drain - typical horror movie (supernatural or natural creature invasion), as well as back-flooding;
:Open Window - more like a mundane burglar, or Hitchcock's 'The Birds';
:Mail slot - 'mundane' magical alternative to fitting down the chimney, where there is no usable chimney (''or'' horror movie, of various kinds); but raises the question of where the "with a special key that can open any door" option is, also, for Santa...
:Kitchen Faucet - another horror movie (supernatural) or a technothriller plot (contaminated water supply);
:Heating vents - another common alternative already given for those without a chimney/chimneyplace (''or'' horror/technothriller fodder);
:Cat Flap - another 'normal' alternative (which, again, does not exclude entry by various threats... or non-resident cats/non-cat pets/wildlife);
:Bathroom Mirror - supernatural (especially 'bad magic');
:Toilet - more traditionally rats or sewer-snakes, with reactions from "argh!" to "ewww...", depending on whether anybody is 'enthroned' at the time;
:Pores Of Your Skin - very much... ewww... (as for (techno)horror threats, it's almost always ''someone else's'' skin and/or sweat that's dangerous, so ''your'' skin
(where you aren't the 'patient-zero' or revenant already) would be something pretty novel)

Genre examples would be good.
...also, there is of course a direct reference to how ''our'' universe seems to have certain universal physical values (e.g. 'speed of light') that might well be different in alternate universes. Whether or not the 'physical constants' we currently know are ''the'' fundemental physical constants (rather than derivative of the actual constant(s) the universe started with), it appears that this control room has access to rather less fundemental 'fundementals' to it. Or assumes that Christmas and Santa (and also probably the various entryways, even when not used by Santa) are universals to the universe that always exist in some form, but perhaps differently configured, in alternate universes.

:I was going to have a go with the table and make "normal use" and "irregular/fictional uses" columns, alongside the label items, but wikilinks on the items themselves would have made the first column less necessary, and wouldn't hurt (if done across the board). e.g. are cat-flaps as commonly known and understood outside of temperate areas (where a house isn't already handily perforated against the build-up of heat, but also need not be so sealed against the cold as to make a cat-flap a potentially harmful vent in the door that keeps the cold weather out) that we can be sure that future readers ''automatically'' know what one is?

Could the title text refer to the (in)famous barking "Jingle Bells"? [[User:The Dining Logician|The Dining Logician]] ([[User talk:The Dining Logician|talk]]) 16:17, 23 December 2015 (UTC)

I would propose a different explanation of the comic. I believe Randall is suggesting that the default American explanation to children of how Santa is able to enter locked houses is logically unsatisfying and seemingly arbitrary, and that the universe would be able to function just as smoothly were that explanation to change without warning. Ponytail is unconcerned about the setting because she knows that it doesn't matter in the grand scheme of things. This is in line with [[1268]], where Randall implies that he would be more comfortable in an alternate universe in which lobsters were perceived as inedible instead of a delicacy. [[Special:Contributions/173.245.55.64|173.245.55.64]] 16:37, 23 December 2015 (UTC)
:I disagree, she is flustered when it happens as shown by Ponytail taking both hands up to her mouth. I would say she is distraught that she cannot remember. Probably her boss would be mad (the one who have made this control panel, and who would know the setting) if he found out. We do not see her response to Megan's suggestion that she will just guess... But I agree that it could be Randall's intention and also that it could be relevant to reference [[1268: Alternate Universe]] --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 18:18, 23 December 2015 (UTC)
::That's a good point, but the tension is gone from Ponytail's body in the final panel and she doesn't say "I forget!". One might argue that she is momentarily concerned that Megan had injured herself, and that she relaxed when she realized that merely one of the constants of the universe had been changed. [[Special:Contributions/173.245.55.64|173.245.55.64]] 18:32, 23 December 2015 (UTC)

Dail shifted two clicks, so now it is either on "Kitchen faucet" or "mail slot". Could be worse... If she gives it another 2 clicks in an attempt to put it back, it will end up on either "Chimney", "Toilet" or "bathroom mirror". Maybe it's best not to mess with it any further... --[[Special:Contributions/141.101.104.16|141.101.104.16]] 18:03, 23 December 2015 (UTC)

I feel the "two clicks" don't necessarily imply the dial has been moved two positions. It could simply mean the dial has been moved twice, making it even harder to guess where it was before the first move. It's also possible, in either event, that the dial has been set back to the original position - in which case, moving it again will definitely set it to something wrong! --Andrew Williams, 23:30, 23 December 2015 (GMT)

Maybe it's also a joke on real-life controls often having no clear "default" value (which, by the way, is sometimes the case for virtual controls as well)? [[Special:Contributions/162.158.102.149|162.158.102.149]] 18:56, 23 December 2015 (UTC)

I think the real joke here is the title "christmas settings", a play on the word "settings". Ordinarily this would imply how one sets up the Christmas dinner, but here it is taken as computer term to tune how Christmas actually works in our universe. -- [[Special:Contributions/141.101.81.84|141.101.81.84]] 21:14, 23 December 2015 (UTC)

It should be pointed out that if the change of the dial, as per the second option, changes the past of the universe to match, that there's nothing to indicate that the comic was not also affected. In fact, this makes sense as the gap at the top between options is indicative of dial styles that block the dial (such as with dials that have a maximum and minimum)because, as such, it makes sense that if ponytail slipped and pushed it, it would go as far as it could in the direction she fell into. This would indicate, with the two clicks, that the dial was originally on kitchen faucet. --[[User:Joshupetersen|Joshupetersen]] ([[User talk:Joshupetersen|talk]]) 19:25, 23 December 2015 (UTC)

I added to the 'speed of light' universal constant explanation, because it's "the speed that things ''like'' light go", and thus acts as an effectively unobtainable speed limit to everything ''not'' like light, rather than light's own specific speed-limit. Having a lower 'c' would not allow any more faster-than-c travel than we might already discover is possible. Also I find 'absolute zero' to be a wholey dubious candidate as a constant. Kelvin (and Rankine) gets set at a 'zero' that seems to be the point of absence of temperature/heat/energy (yes, I know they're not strictly the same, with temperature being the most incorrect term of them all, but I'm grouping them as common equivalent terms to a layperson) and, like Celsius (and Fahrenheit), has a unit spread according to an anthropocentricly decided 'range' and subdivisions. Other constants that affect the behaviour of water (or brine+ice/body temperature), including the atmospheric pressure we live under, would change the absolute value of the non-absulute measures but not change the zero value of the absolute measures.

}}

==Explanation==
[[Ponytail]] is showing [[Megan]] around in her facility, and as the comic begins they enter a new room (''over here we have'') where she has the ''Universe Control Panel''.

A "Universe Control Panel" would be a set of dials to control the universe, and anyone having access to a room with these controls would from our point of view be in a God like position. If such a room did exist it would most likely be situated outside our universe (a dimension outside, and not necessarily in another universe). Since this comic was released just before {{w|Christmas}}, looking at it from a {{w|Christian}} point of view, this would be {{w|Gods}} domicile and his control room for the universe would probably be located in {{w|Heaven}}.

Seen from a physicist's point of view, the typical panels for such a control room would be with dials to control the specific size of {{w|Physical constant|fundamental constants}} of the universe such as the {{w|speed of light in vacuum}}, {{w|Planck constant}} and the {{w|fine-structure constant}} to mention a few - see more under the trivia section [[#Physical constants control panel|Physical constants control panel]].

But the first control panel they reach includes the dials that control {{w|Christmas}}. So these control panels are either much more detailed than just physics constants (or do not consider these underlying constants at all). That we see this option as the first is, of course, because this is a [[:Category:Christmas|Christmas comic]] released on the 23rd of December.

From Ponytail's comment it is clear that this is just one of several panels with dials, and on the panel for Christmas there is more than one dial. We only see one of these up close (to get an idea of how they work, and for the sake of the joke).

In the second panel, Megan and Ponytail have not reached the control panel yet, so it is the reader, and not them, who sees the dial, which controls how {{w|Santa Claus}} enters people’s houses: The ''Santa enters houses through''-dial, has [[#Options for Santa|ten different possible settings]]. The one it's set to at this point of the comic is the traditional ''chimney''. Among the other nine there is the more logical option ''open window'', but surprisingly here is not option called ''the door''. But the other eight, are increasingly weird or even impossible (though of course not for Santa, who can deliver a billion packets in one night and fly in a sleigh drawn by flying reindeer…). These options ranging from the ”feasible” like ''mail slot'', ''heating vents'' or ''cat flap'' to the impossible/ridicules (some even disgusting) as ''kitchen faucet'', ''shower drain'' or ''toilet'' over the truly magical ''bathroom mirror '' and to the downright unpleasant - ''pores of your skin''. (See [[555: Two Mirrors]] regarding the mirror version).

As Megan and Ponytail are on their way to the next stop on the tour of these facilities Megan trips and catches herself on the Santa dial, messing it up by clicking it twice. Ponytail is disturbed by this and holds up her hand to her mouth. The reason for this is obvious when Megan asks what it was set to before so as to undo the mishap, because Ponytail tells that she has forgotten. So they cannot put it back right. This kind of proves that Ponytail is just a guide, and not the creator of the control panels.

As so often seen with human behaviors (if they are indeed human beings at all?) Megan says she will simply take a wild guess and hope she get it right. As the only thing she really knows is that it is not on the right setting now, there is only 1/9 that she will get it right assuming she will at least change it away from the setting she ended up on.

As we can see in the comic the dial clicks twice, implying it has moved two positions; Megan has thus most likely changed the dial to either "kitchen faucet" or "mail slot." As we do not know which of these she will now change away from, It is impossible to guess from the comic where she end up putting it, all ten options are possible. 
Since this comic was released on the 23rd of December, we are likely to find out in less than two days, if Santa comes out of the pores on our skin, or just through the mail slot... Only the first of these options will for certain be detected by someone…

As it is Ponytail who are showing Megan around, it is thus the first time Megan even hear about these dials, and she has no idea about where the Santa dial was pointing before. The reason why Ponytail cannot remember to which option the dial was set before is most likely because she is not part of our universe, and also not the creator of the control panel. If this is a control room outside of our universe these settings will not affect the two girls but they also have no need to know about Christmas on Earth. Anyone with access to these control room, might not particularly care for what happens on Earth, which is just one of a multitude of planet and stars that needs to be controlled from this control room.

An alternative explanation for the reason Ponytail has forgotten, is that the universe immediately updated its settings to the latest selection, once Megan released the dial, changing all previously existing folklore and memories in existence to match (this will only make sense if the two girls are part of the universe that they are in control of). Where previously it was widely known that Santa Clause entered through the chimney, it is now widely known that he enters through kitchen faucets or mail slots (depending on Megan's selection). This makes it impossible to remember what the original setting was. Of course if this happened then how do they remember that it was changed in the first place? Megan would now know what that is on the correct position and leave it be. So this explanation makes little sense...

The title text continues this by showing another ad-lib dial: ''[[#Options for dogs|Sound dogs make]]'' ranging from the norm (barking) to cat sounds (hissing), very embarrassing for a dog) over "lightsaber noises" and speech to swearing. This is a dial, most likely on another control panel for animal sounds (but it could of course specifically be the sound a dog would make in response to Santa's entry, by whatever method?)- It would thus give the same option of changing the expected vocal response of the dog away from (our norm of) barking, as the other dial with the way Santa enters the house. In popular culture, talking dogs are a commonly used trope; in contrast, swearing "dogs" are few, the most famous being {{w|Triumph, the Insult Comic Dog}}, a puppet created by {{w|Conan O'Brien}} and {{w|Robert Smigel}} and performed by the latter.

The comic might also be a joke on real-life controls often having no clear "default" value - which, by the way, is sometimes the case for virtual controls as well.

==Options for Santa==
*Below is a table with the ten possible settings for ''Santa enters houses through...''; starting with the originally chosen standard option and going clockwise through the rest:

==Trivia==
*In the [http://www.explainxkcd.com/wiki/images/archive/7/73/20151223160450!christmas_settings.png original version] of the comic Ponytail erroneously said: ''These dials, for example, '''controls''' Christmas.''
**This was soon changed to the current (and grammatically correct) version with out the "s" at the end of controls ''These dials, for example, control Christmas.''
**Thus proving that it was intended that there where more than one dial, we just see the one that Megan later changed by mistake for the sake of the joke of the comic.

===Physical constants control panel===
*Below is a table with ten of the most likely dials to find on a Universe Control Panel for {{w|Physical constant|physical constants}}.
**(Please feel free to reorder or change out constants, if there are some “more important” constants left out, or reorder the list if that would feel more appropriate), and add more explanation.
**If just one of these constant had a slightly different value, life as we know it (or even star formation) might not have been possible, (see the {{w|anthropic principle}}). So it was good that it was only the Santa setting Megan screwed-on (up).

1620: Christmas Settings

2015-12-23T13:36:43Z

162.158.152.227: /* Explanation */ Previous edit appears to mis-read that as a sequence of sounds, not options for the single sound a dog makes.

{{comic
| number = 1620
| date = December 23, 2015
| title = Christmas Settings
| image = christmas_settings.png
| titletext = SOUND DOGS MAKE: [BARKING] [HISSING] [LIGHTSABER NOISES] [FLUENT ENGLISH] [SWEARING]
}}

==Explanation==
{{incomplete|Created by a BOT , then partially explained by someone in a rush. Please update, then remove this message.}}

A "Universe Control Panel" would be a set of dials to control the universe. Two "universal" parameters are considered: where does Santa Claus enters houses through and, in the title text, what sound dogs make.

[[Megan]] and [[Ponytail]] are looking at the Santa Claus dial. The dial has many settings; The one it's set to is the traditional chimney, but there are some other logical ones like the open window (Surprisingly not the door though), and increasingly weird and impossible ones ranging from the mail slot to the pores of one's skin.

As Megan approaches to get a better look however, she trips and catches herself on the Santa dial, messing it up. She asks what it was set to before so as to undo the mishap, but Ponytail forgets, so Megan simply guesses. (Notably, we hear/read the dial only clicks twice, implying it has moved two positions; Megan had most likely set the dial to "Kitchen faucet" or "Mail slot").

A possible explanation for why neither Ponytail or Megan can remember to which option the dial was set before, is that the universe has updated its settings to the latest selection, changing all previously existing folk lore and memories in existence to match. Where previously it was widely known that Santa Clause entered through the chimney, it is now widely known that he enters through kitchen faucets or mail slots (depending on Megan's selection). This makes it impossible to remember what the original setting was.

The title text continues this by showing another ad-lib dial: "SOUND DOGS MAKE", ranging from the norm (barking) to "lightsaber noises" to speech to swearing. This may or may not be on the Christmas control panel (specificially in response to Santa's entry, by whatever method?), but would give the same option of changing the expected vocal response of the dog away from (our norm of) barking.

I suspect that the extra limbs should be removed when there are 100+ and Vitamin D levels checked when the nmbr of limbs is in an acceptable range... does IBM use a ticketing system? [[Special:Contributions/162.158.91.194|162.158.91.194]] 08:39, 21 December 2015 (UTC)
: Unfortunately the algorithm as shown in the cartoon has the conditions for those two steps exactly the other way around, making even less sense medically. --[[User:Svenman|Svenman]] ([[User talk:Svenman|talk]]) 14:30, 21 December 2015 (UTC)

It seems a normal patient would end up mostly unscathed and in an infinite loop in the lower right corner. [[User:Benjaminikuta|Benjaminikuta]] ([[User talk:Benjaminikuta|talk]]) 09:01, 21 December 2015 (UTC)
:Uhm no. You would normally have an oxygen level above 50% of what is expected. (It should be close to 100% if I understand [http://www.nonin.com/Normal-Oxygen-Level this correctly], which I may not...). This means you have had your skeleton removed. If you survived this you are squeezed until fluid comes out. (Probably not necessary after the skelerectomy). But then you end up in the lower right corner. Of course you can also get there after just getting an oxygen injection, but only directly if you are not comforted when the program tries. If you where comforted you will lose some limbs. And then end up in the lower right corner. No matter what if you are still OK (could be possible) when reaching here, you will be asked about your pain level. And even if you start by saying 0-8 many many times, getting as many scalp massages, you will just get the same question, until you say 10 then your eyes will be removed. But no matter what, if you are asked such a stupid question enough times you will surely at some point say something else than 0-10, and then you will die, as this answer will take you down the last path of the program (and only exit of the cycle according the to glitch mentioned in the title text), and this will end up with the program performing an autopsy on you, thus cutting you up and removing all organs etc. So no you will not be able to go unscathed infinitely, and even if you kept saying 0-8 you would eventually die from thirst. ;) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:24, 21 December 2015 (UTC)
::Yes, normal oxygen saturation is 98-100% in air. If it drops below 95% you will be in trouble, if it drops below 85% you're likely dead. [[User:Kev|Kev]] ([[User talk:Kev|talk]]) 09:54, 21 December 2015 (UTC)
::: Actually you can go a lot lower than 85% and still recover. You lose consciousness at about 55% on average, so you could dip below 50% for maybe a minute and still recover with appropriate treatment. It is unclear exactly what "inject oxygen" means, it could mean intubate and actively ventilate with oxygen (appropriate) or it might mean use a syringe & needle to literally inject an oxygen embolus (which would do more harm than good). It could even mean a blood transfusion, because there is oxygen carried by the red blood cells (appropriate). [[User:Martin|Martin]] ([[User talk:Martin|talk]]) 22:28, 21 December 2015 (UTC)

This might also partially be a reference to machine learning, which Watson apparently uses: badly designed ML systems often build models which produce the expected results for the training data, but do something unexpected or wrong with real data. See [https://en.wikipedia.org/wiki/Overfitting#Machine_learning]. That said ... 'dissect doctor for parts' doesn't seem like a reasonable response to any training input ;) [[Special:Contributions/162.158.39.208|162.158.39.208]] 10:41, 21 December 2015 (UTC)

The noted "unrelated actions" aren't all entirely unrelated. The coughing blood one is interpreting backwards (so "is patient not coughing up blood because the patient is not here to do so?"), the vitamin D one is somewhat logical (vit D is part of the chain that converts calcium to bone, low vit D can cause bone loss, but high vit D is basically harmless), and the green fluid is slightly sane but too vague (logic appears to be that green fluid indicates severely infected and/or necrotic tissue, for which cauterizing might be a valid treatment step in extreme situations). Weirdly specific might be a better header? [[Special:Contributions/141.101.106.197|141.101.106.197]] 11:57, 21 December 2015 (UTC)

So what happens if the skeleton has exactly the right number of bones? --[[Special:Contributions/162.158.153.71|162.158.153.71]] 12:32, 21 December 2015 (UTC)
: Indeed this case is not covered, thus making the algorithm faulty even on an abstract logical level. --[[User:Svenman|Svenman]] ([[User talk:Svenman|talk]]) 14:33, 21 December 2015 (UTC)
: What is the "right" number anyway? The number of bones in a normal human is not constant: it changes from 270 at birth to 206 as an adult. [[User:Martin|Martin]] ([[User talk:Martin|talk]]) 22:35, 21 December 2015 (UTC)
:: {{w|Human_skeleton}} : "It is composed of 270 bones at birth – this total decreases to 206 bones by adulthood after some bones have fused together" [[Special:Contributions/162.158.255.46|162.158.255.46]] 22:32, 22 December 2015 (UTC)

the Request organ donation/Remove organs part reminds me of Live Organ Transplants segment in ''{{w|Monty Python's The Meaning of Life}}''. --[[User:Valepert|valepert]] ([[User talk:Valepert|talk]]) 12:53, 21 December 2015 (UTC)

100 could be a reference to 4 in binary (4+ limbs / less than 4 limbs) [[Special:Contributions/141.101.99.39|141.101.99.39]] 12:59, 21 December 2015 (UTC)

This algorithm certainly does not exit without the death of the patient, however, such a death can result from old age as long as the patient can make it to the bottom right infinite loop and continuously reports a number from 0-9 for pain. It IS possible to make it to that loop alive. Extremely low blood oxygen levels have been recorded in healthy Everest climbers, but the article I read gave the results in kilopascals, not in % so I don't know how that converts. However, repeatedly reporting a pain level of 0-8 would result in continuous scalp massages, which may actually be considered pleasant.

I think this may be the least undesirable path through the flowchart:
START > Draw blood (enough to lower oxygen saturation to 49%) > Record name > Measure height and weight > Measured height/weight happens to match standard chart exactly > No surgery needed > Not coughing up blood > Still here > Record pulse rate > No screaming (unconscious due to low O2 saturation) > O2 saturation below 50% > Inject oxygen > Comforting succesful > Review medical history > Skin grafts > Fewer than 100 limbs > Good vitamin D > Check build environment > Rinse with saline > Phone battery level is high > Sync photos > General anesthesia > Discharge [[User:Martin|Martin]] ([[User talk:Martin|talk]]) 22:51, 21 December 2015 (UTC)
:Nope, that path doesn't work. First, injecting oxygen may do more harm than good, as previously mentioned. Second, you'll be unconscious, so comforting will be unsuccessful. Third, having fewer than 100 limbs actually leads to the path where some are removed (possibly an error in the chart?). Fourth, due to the bug, discharge leads to hunting you down and capturing you again. [[Special:Contributions/108.162.249.161|108.162.249.161]] 01:32, 22 December 2015 (UTC)
::First, it may or it may not... I'm hoping not! (see above for discussion of possible ways to "inject" oxygen) Second, I'll be conscious again because my oxygen saturation has now been restored, so comforting is possible. Third, please look at the updated version of the flowchart, fewer than 100 leads to measuring Vitamin D. Fourth, there is no pathway shown from discharge to hunting down and capturing: I assume that START is admission to the hospital, therefore once discharged from hospital I have escaped Watson's clutches.

:::::No luck on getting infinite skin grafts, I'm afraid. Watson won't draw blood again, so you won't be able to keep failing the oxygen saturation test. Besides, keeping oxygen perpetually under 50% would be fatal in itself. Maybe that's the best way to go: blacking out from oxygen deprivation.

Another infinite loop is in the upper right; if the patient's phone battery is low, defibrillate, then check phone battery condition again.

-I don't know about the paper specifically, but by the principle of microscopic reversibility (https://en.wikipedia.org/wiki/Microscopic_reversibility), not only can you turn the products back into the reagents, you can do so using the exact same mechanisms. Chemical reactions are always going both ways, and they will tend towards the equilibrium from the higher concentration ~pure meth. That does not say anything about practicality, I am not versed in meth-synthesis, but maybe it involves a process with a product harder to acquire than pseudoerphine (maybe because it is useless and simply disposed of) which would be required as a reagent in this case.

Codeine was originally a cough suppressant. It was and is the most effective and reliable cough medicine available and very safe in the usual quantities. You can't get it, though -- for an ordinary cough -- because some people like to use a lot of it for fun and sometimes get addicted to large quantities of it. You could synthesize it or an analogue of it from heroin or oxycodone about as safely as any kitchen chemistry because they share the same opium base.

The principal cold medicines are cough suppressants (codeine is best -- other things work but much worse), decongestant (pseudoephedrine works great, phenylephrine is no more effective than a placebo), mild anti-inflammatories like ibuprofen, and antihistamines for anti-sneezing (there are many good ones based on Seldane like Claritin). Most people like to combine those at nighttime with a good mild tranquil sleep promoter -- I recommend whisky or rum. Note that pseudoephedrine is banned in some states of the USA such as Oregon.

I take the title text differently - that since buying pseudoephedrine-containing drugs legally in a larger than minimal quantity (e.g. to stockpile them at home to have them at hand when you need them) already makes you a criminal suspect with 100% certainty (because you have to show your ID), it may be safer to buy illegal drugs on the black market, where you have at least some chance of not being caught. As for turning meth back to PE - it is possible for sure, since all chemical processes are reversible in one way or another, but I am not versed enough in organic chemistry to say if it is easier or harder than the other way round. -- [[Special:Contributions/162.158.90.224|162.158.90.224]] 12:33, 18 December 2015 (UTC)

This is actually semi serious. When I have a cold, literally the only thing that works is pseudoephedrine. And Sudafed, which is the registered label for pseudoephedrine, now sells Sudafed without the pseudoephedrine. In a cold induced daze I have actually managed to buy the not pseudoephedrine Sudafed, and only realized my mistake several days later when the cold symptoms aren't going away.

Apologies if I've missed this exact take on the hovertext, in amongst the above, but ''my'' reading of it is that right now, where illegal drugs are unobtainable, legal drugs are converted into them (for fun and/or profit). But the problems of getting the legal drugs are even ''greater'' (either because of the confusion, the pharmacy refusing to sell large amounts or just the threat of the watch-list) and so the illegal ones are more obtainable, in the hope of being back-converted into the desired 'legal' ones.

Also, there's also [http://www.bbc.co.uk/news/magazine-35091242 this issue] about multiple packet designs just being the same thing, that happened recently.

The mouse over text makes it fairly clear that it's a joke about opposites. If anything could be added to the explanation as it stands, I might clarify that red and cyan are specifically colors of light. When shone on a single area (and therefor mixed) these two colors will create white light. When these colors of light are represented on a color wheel, they are placed opposite each other. So cyan and red in this sense fit as opposites, like big and small, alkaline and acidic. {{unsigned ip|108.162.227.125}}

I want to visit the current description in the article that "Cyan is a greenish-blue"... It is ''literally'' green-blue. No '-ish' about it. #0FF in an #RGB triple-nibble hex format. If talking about it by visual impression, rather than by components, cyan doesn't ''look'' green at all. It just looks like light-blue. At least to your current author. Whilst I'm not diagnosed as colour-blind, I know that (for example) even normal male and female perceptions of colour can have different resolutions and impressions of various hues.

And now some even more confusing datam-points, of an otherwise unrelated nature: in the default pallette my copy of OpenOffice uses (the handiest thing to check, outside of direct HTML encoding) the colour I could enumerate as #0FF (by sight alone... not having bothered to 'pipette' sample a screen grab of it in a graphics editor, to get exact values) is called "light cyan". I can't find non-light "cyan", but it'd probably be around #088 (that might be the value the one labelled "turqoise" has, which ''does'' seem to have a green-ish component, so might be more like #097ish), as #00F (pure blue, by my own assessment) is called "light blue" and the colour labelled "blue" (but that I'd call ''dark blue'') looks roughly #008-ish.

Never left a comment on a wiki before, so no idea if I'm doing this right, but aren't the grease soaked vegetables just chips (or fries to my good American colleagues), and the brick of cheese a reference to the cheese in the comic?

Funny how comics about food always cause more comments than any other regular comics ;-) I'm definitely on the idea that this is about toppings for a pizza and not fries. No one claims chips/French fries are healthy, but having veggies on a pizza is considered healthier than one just with four kinds of meat. Many people won't even eat pizza with vegetables. But of course they do not make it healthy. --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 13:37, 15 December 2015 (UTC)

The mouse over text makes it fairly clear that it's a joke about opposites. If anything could be added to the explanation as it stands, I might clarify that red and cyan are specifically colors of light. When shone on a single area (and therefor mixed) these two colors will create white light. When these colors of light are represented on a color wheel, they are placed opposite each other. So cyan and red in this sense fit as opposites, like big and small, alkaline and acidic.

For some reason, this made me laugh extremely hard. I've been up all night and maybe it's sleep deprivation, as it makes me do weird things, like bingewatch on several ISS videos simultaneously.

There is also a common stereotype that a car's color reveals something about its owner's psychology (e.g. [https://www.thecaretrust.ie/colour-of-car-personality here]).

Of course full Dumbo Ears are far more overscale than these, so maybe the dog has ''some'' floating skills, the ears are merely attitude controls. - (And I can't believe I'm now discussing the precise nature of the airworthiness of a dog.

My original interpretation of the title text was that the "string" in the dog's mouth was the line connecting the dialog to the characters, e.g. the two lines connecting Megan and Beret Guy's dialog to their characters in the second panel. So the voice drifting down from the sky was literally the words "Kites are fun!" being pulled (perhaps uttered?) by the dog.

Is there any direct implication that these objects ("kite" and the dog) are really in the sky? Maybe it was draw like this to trick the readers but instead it is a forced 2D perspective and the dog is just fighting with the Beret Guy? I guess we can also assume that while Beret Guy says "I'll go get mine, once I finish walking my dog!" he actually means it (walking - not flying/floating).

}}

==Explanation==

{{incomplete|Comic needs to be referenced with recurring themes (megan loving kites, beret guy's weirdness, etc.). Title text is a master-stroke. :) }}

In this comic, we see Megan and Beret Guy holding two skyward strings. Megan's string is connected to a kite, and she (like the reader) initially assumes that Beret Guy's string is as well-- only for it to be revealed that he is not holding a kite-string, but instead a leash for a small dog. This move on Randall's part is known as a 'Bait and Switch', a technique that relies on human intuition and pattern seeking in order to play a trick on the viewer. The 'bait' of the bait and switch is made possible by the lack of detail in XKCD-- it ought to be assumed that if a more realistic comic were to be drawn, we would spot the dissimilarities between a leash and a kite-string right away. The 'switch' portion of the bait and switch comes with the added humor of an unconventional dog that floats much like a kite instead of walking on the ground, so the joke comes by surprise and with little warning to the reader. 

Beret Guy is fond of unconventional approaches to standard conventional issues. More detailed information about Megan and Beret Guy arriving soon, one hopes. 

The title text plays a subversion once more on the unsuspecting reader, with the kite being flown as expected-- albeit with an added payload of one beret-wearing human and flown by a small floating dog. 

==Transcript==

{Megan and Beret Guy are flying (seemingly) kites.} 

Megan: I love kites. 

Beret Guy: Hey, Me too! 

Beret Guy: I'll go get mine, once I finish walking my dog! 

Beret Guy: C'mon boy! {and starts tugging on the string going into the sky} 

Dog: Arf, Arf, Arf! {comes down from the sky}

{Megan looks curiously as Beret Guy walks away with Dog and string}

Technically, in the world we live in, robots are barely following ONE law - obey orders.

Sure, most robots are built with failsafes, but nothing nearly as effective as Asimov's law, which makes permanent damage to robots brain when it fails to protect humans.

To additionally summarise: The permutations of laws can be classified into two equally numbered classes. a) harmless to humans and b) deadly to humans. In a) Harmlessness precedes Obedience, in b) Obedience precedes Harmlessness. Since robots are mainly tools that multiply human effort by automation, the disastrous consequences are only a nature of the human effort itself. Randall's pessimism is emphasized by the contrast between the apparent impossibility of the implementation of the harmlessness law and the natural presence of the "obedience law" in actual robotics.

}}

==Explanation==
{{incomplete|Very basic first draft, and I'm pretty inexperienced [[User:Halfhat|Halfhat]] ([[User talk:Halfhat|talk]]) 09:38, 7 December 2015 (UTC) you should also check my awful spelling [[User:Halfhat|Halfhat]] ([[User talk:Halfhat|talk]]) 09:46, 7 December 2015 (UTC)}}
This comic explores alternative orderings of sci-fi author Isaac Asimov's famous {{w|Three Laws of Robotics}}. These laws form the basis of a number of Asimov works of fiction, including most famously, "I, Robot". The comic answers the generally unasked question: "Why are they in that order?"

The joke here is that any alternative ordering of the three laws results in ridiculous worlds; two of these are designated yellow (pretty bad) and three results are designated red ("Hellscape").

;Ordering #1:This is the original ordering.
;Ordering #2: The robots value their existence over their job and so many would be much less functional. The silliness of this is portrayed in the accompanying image, where the robot laughs at the idea of doing what it was clearly built to do (explore mars) because of the risk. This personification is augmented by the robot being switched on on Earth and ordered by the fleshy human known as [[Megan]]. The personification is humorous since it is a very nonhuman robot.
;Ordering #3: This puts obeying orders above not harming humans which means anyone could send them on a killing spree, resulting in a "Killbot Hellscape". It should also be noted humor is derived from the superlative nature of "Killbot Hellscape", as well as its over the top accompanying image, where there are multiple mushroom clouds (not necessarily nuclear). It also appears there are no humans, only robots.
;Ordering #4:The next would also result in much the same, the only difference here is that they would be willing to kill humans to protect themselves.
;Ordering #5:The penultimate would result in a unpleasant world, though not a full Hellscape, where the robots would not only disobey to protect themselves, but also kill if necessary. The absurdity of this one is further demonstrated with the very unhuman robot happily doing repetitive mundane tasks but then threatening its user, the terrified relic of the age of men known as [[Cueball]].
;Ordering #6:The last also results in a Hellscape wherein robots not only kill for self defense but will also go on killing sprees if ordered as long as they didn't risk themselves.

To summarise: There are two main distinctions between the 'normal' 3-laws and the variations. The first is where Self-protection is put ahead of Obedience. This results in a world where robots may be considered no longer the useful workers for humanity that they are supposed to be. The second is where Obedience supercedes Harmlessness, and means that robots are ''threats'' to humanity (although only if they are ever given the opportunity to be so).

The former, alone, merely creates frustration, in one scenario. The latter, alone, allows humans to use robots as their proxies for warfare, as per two scenarios - although the hellscape could be 'easily' avoided if nobody bothers to order to start (or continue) military action. Both ''together'' upgrade both the frustration and warfare aspects, creating 'unstoppable killing machines' - our only hope is that nobody ''ever'' orders them into killing-mode, or gives them cause to consider themselves under threat, resulting in an uneasy peace on the perpetual edge of tipping over into war.

The third 'law inversion', with Self-protection being put ahead of Harmlessness, is necessarily inherent in the 'worst' Killbot Hellscape scenario, whilst really only adds a nuance between the first two Hellscape scenarios, where the orders themselves are not explicitly anti-human.

The titletext further adds to ordering #5 by noting anyone wishing to trade in their self-driving car could be killed, despite it (currently) being a standard and mundane and (mostly) risk free activity.

==Explanation==
{{incomplete|First go at an explanation, but from a transatlantic perspective...}}
In popular fiction (and maybe in part in fact) the "Baking Soda And Vinegar" volcano is often a staple image of the science nerd at the science fair, unless all the science nerds are doing ''real'' imaginative science and the student(s) with the volcano exhibit are dragging out the old hackneyed stereotype. It may also be age-dependent, this being something that is relatively advanced science for the lower grades but rather a childish experiment in the hands of older students.

As the adult is probably about to point out, the 'volcano' exhibit doesn't (usually) actually demonstrate anything about volcanic activity, it is just simple chemistry - such as you usually conduct in a simple test-tube - dressed up to look more impressive, often with dye or other additives to make the 'lava' look realistic for the model, but unrelated to the geology it is being represented as.

''This'' volcano, however, seems to go beyond simple chemistry. The model replicates many of the dangers (aside from the pure lava) of a volcano, and appears to have been given scaled-down vehicles trying (and failing) to escape the dangers of the resultant mud-flows being modelled.

Even more, this is not an isolated 'model volcano' but a vinegar-powered representation of a geological 'hot spot', such as with the islands of Hawaii, in which the spot moves with respect to the Earth's crust (or vice-versa) and generates a new volcano some way off. Despite this model being supported on a table, it appears that the 'project' extends some way beyond that and has somehow contrived further eruptions away from the table, the room and probably even the building.

The 'project' seems to be turning into a very thorough model of a much larger geological process and destined to produce a ''very real'' volcanic winter. Where a magma-powered volcano could produce vast clouds of dust, preventing the sun's energy from warming the Earth, in this case it's the airborne salt (probably sodium acetate) from the chemical reaction that appears to be in danger of causing crop failure. There's no mention of the corresponding environmental effects of the vast amounts of carbon dioxide (and/or aqueous carbonic acid) necessarily released in proportion to the ejected salt (presumably itself not left in solution).

The 'project' seems to be turning into a very thorough model of a much larger geological process and destined to produce a ''very real'' volcanic winter. Where a magma-powered volcano could produce vast clouds of dust, preventing the sun's energy from warming the Earth, in this case it's the airborne salt (probably sodium acetate) from the chemical reaction that appears to be in danger of causing crop failure. There's no mention of the corresponding environmental effects of the vast amounts of carbon dioxide (and/or aqueous carbonic acid) necessarily released in proportion to the ejected salt (presumably itself not left in solution).

The only experience I have with such a volcano exhibit is from US TV programmes representing the nerds (or the desperate non-nerds with no imagination) at a science-fair in Stateside schools, but I laid down my impressions of the tradition anyway. No embedded links to anything, as yet, as I expect other people will know what needs explaining (or re-writing) better than me. - I was going to go onto Supervolcano territory, but I'm not sure it's supposed to be more than 'regular' increased volcanic activity, outside, albeit through the power of acid/base interaction (thus salt being the equivalent of volcanic dust plumes, no doubt).

1611: Baking Soda and Vinegar

2015-12-02T09:54:11Z

162.158.152.227: /* Explanation */ First go. Hopefully.

{{comic
| number = 1611
| date = December 2, 2015
| title = Baking Soda and Vinegar
| image = baking_soda_and_vinegar.png
| titletext = Sure, it may not meet science fair standards, but I want credit for getting my baking soda and vinegar mountain added to the Decade Volcanoes list.
}}

==Explanation==
{{incomplete|First go at an explanation, but from a transatlantic perspective...}}
In popular fiction (and maybe in part in fact) the "Baking Soda And Vinegar" volcano is often a staple image of the science nerd at the science fair, unless all the science nerds are doing ''real'' imaginative science and the student(s) with the volcano exhibit are dragging out the old hackneyed stereotype. It may also be age-dependent.

As the adult is probably about to point out, the 'volcano' exhibit doesn't (usually) actually demonstrate anything about volcanic activity, it's just simple chemistry - such as you usually conduct in a simple test-tube - dressed up to look more impressive, often with dye or other additives to make the 'lava' look realistic for the model.

''This'' volcano, however, seems to go beyond the chemistry. The model replicates many of the dangers (aside from the pure lava) of a volcano, and appears to have been given scaled-down vehicles trying (and failing) to escape the dangers of the resultant mud-flows being modelled.

Even more, this is not an isolated 'model volcano' but a vinegar-powered representation of a geological 'hot spot', such as with the islands of Hawaii, in which the spot moves with respect to the Earth's crust (or vice-versa) and generates a new volcano some way off. Despite this model being supported on a table, it appears that the 'project' extends some way beyond that and has somehow contrived further eruptions away from the table, the room and probably even the building.

The 'project' seems to be turning into a very thorough model of a much larger geological process and destined to produce a ''very real'' volcanic winter.

If you think sour cream and pancakes is not a traditional combination, you've never been to Russia. We put sour cream in a lot of things, really, but pancakes especially. That applies almost as well to sour cream and ketchup (though that is just a pair of commonly combined condiments, not a food item in itself). I do, however, agree with the commentor above (even regarding sour cream). Incidentally, I had to google "relish" - apparently it's a general term for a big variety of chopped-vegetable items. The Russian name for one particularly common type literally translates as "eggplant caviar". Goes nicely with ham, is applied to pancakes occasionally. --[[Special:Contributions/162.158.180.191|162.158.180.191]] 20:51, 27 November 2015 (UTC)

It will be interesting to see if all items will be checked of eventually when people from many different countries comes by? I checked of pancakes and ice cream. I put ice in almost every time I make sweet pancakes. Yummy. But we also have "food" pancakes (not sweat) with meat in them. And I'm note talking about tortillas or burrito pancakes. Made exactly like normal sweet pancakes without sugar and with salt. In The Netherlands they have pancake houses where the toppings is more like that of a pizza, and then after wards they drop on some kind of syrup... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 21:06, 27 November 2015 (UTC)

Avocado and ice cream is traditional? Really? I mean, the novelty ice cream places (bacon ice cream, beer ice cream, Tabasco ice cream, you know the drill), sure, but where is that a traditional pairing? ... However, I'm putting in another vote for sour cream with pancakes. Especially if you consider crêpes and associated acts as in the pancake category, so there's the whole world of savory pancakes out there.

But I know that many people really love these items, and that would not make it a bad combination to put sour cream and avocado together. I just would not wish to eat it for my personal taste. That I do not like it, does not make it disgusting. But I would be sorry if someone tried to make me eat it. But not get disgusted because other people eat it in front of me.

Just thought this was interesting, when you "complete" the game by dropping coins, the following line of javascript is run, which sends your result to the server (L is number of coins, z is seconds used):

Haven't read all the comments above so maybe someone has written about it?
If you click up it seems to count how many times. So it will just show white and then when you release again, it will take longer to hit the ground the longer you have pushed up. Tried with 100 clicks (9-10 seconds) and 200 clicks (20 seconds).
I got about 163 coins in about 15886 seconds. (4 hours and 24 minutes.) That was with breaks. It was written so shortly on the screen I did not manage to take it down for certain. But after that I read here about the 169 and found that there where at least three in the volcano I had not noticed at first. And it seems likely that there would be three more I have missed.

Just added in the 'collision detection' section the text "On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile." To expand upon this, if this is a risk to anyone else (I'm reliant on mobile internet, being away from any comparable landline capability) then you need to look out for perfectly horizontal/vertical edges. For example, hovering up the side of the Washington monument and encountering (typically above the 'bricks' line) a completely flat top. Drifting onto that soon gets you embedded in the remaining Monument, somewhere well below the eventual tip. Alternately, drifting sideways over the landscape and discovering a perfectly vertical cliff downwards (just past the bowling pins is a prime location) tempts you to drift down it and then suddenly the solid land 'happens' around you, forcing a page-refresh and restart (though doubtless there's also various console tricks that could be used). The well, also 'opens out', but it's a lie. I've ended up trapped 'in white' below the now closed black blocks that surround the well bottom (and not found any way back up). But if there a 'texture' (like other cliffs) or 'slope' (like the real Monument edge) to the surface, you're probably Ok. It's a genuine surface or wall that you can generally navigate around without fear of being misled. (Or so is my experience.)

We definitely need a better presentation of interesting objects/locations and their coordinates. Now, we have quite comprehensive multi-level bullet list and a newly-started table. Neither is perfect. We need some form that will show clearly what is where and where it belongs.

Issues to solve:
* Many objects are large and a single coordinates pair simply don't describe them well. We need a clear presentation form that will allow putting both a single pair and several ones, e.g. top and bottom for thin vertical objects (e.g. poles, The Monument), four corners for objects occupying large swaths etc.
* Grouping - we need to group objects that belong to an area, like all things within the Star Destroyer etc. Multilevel bullets are ok, but how to do that in a table?
* Order - within groups and between them, we need some ordering that will organize the entries. For example left-to-right then top-to-bottom or something like that.
* Coordinates system - the "native" game coordinates are large numbers, and negative values for the y coordinate to boot. Someone proposed setting a new origin and counting from there. I think it's a good idea, but will require a firm decision, rewrite of radar code and recalculating of all coordinates written down so far.

Any ideas?

:If it weren't for so much effort put in already, I think that we ''could'' re-class features as follows:
:* All coin locations, and/or links to the locations they are associated with (e.g. "in original game area" and "carried by a quadcopter drone"), if that's not considered 'unfair' to those wanting to actually play the game (without the self-discipline not to browse the list ;).
:* Locations of all characters, certainly all stick-figures, but maybe also 'wildlife' (or automata) of notable types.
:* All monologues/dialogues/labels (albeit that this is almost entirely a subset of the prior list).
:* Other notable landscape (or structural) features that are more than mere 'flavour' (e.g. the T-shaped mushrooms/whatevers to the east, but not random ground-boulders).
:* Notable move-through spots; inclusive of 'sink-into'able waters/magmas (waist-height, neck-height, fully-submerged?), even when not featuring further hidden routes, but excluding vegetation (ground-grasses/tree-trunks) that ''mostly'' are pass-throughable.
: Some of these are themselves useful references to other items (e.g. "inside front of Blockade Runner" or "beneath eastern stretch of magma") and so can probably be sub-grouped as all items in a given structure ("coins within the initial play area", "characters/speech within the Star Destroyer") and some things do occupy a swathe (the 'play area', the Monument, the ships, the kites, with their strings; the hail of (regular) torpedoes). And I bet there's a whole lot of arguments about what level of detail we could go to... [[Special:Contributions/162.158.152.227|162.158.152.227]] 10:21, 27 November 2015 (UTC)

Just thought this was interesting, when you "complete" the game by dropping coins, the following line of javascript is run, which sends your result to the server (L is number of coins, z is seconds used):
(new Image).src = "//xkcd.com/events.gif?coins=" + L + "&seconds=" + z;
Don't be tricked by the .gif extension, it doesn't show an image when opened, and the server probably handles this request by logging it to somewhere. {{unsigned ip|141.101.80.87}}

:In some cases you can come in from the side as opposed to trying to come down through or up through something.

The list of "areas" in the map would be much easier to read, and much easier to correlate with the map, if the origin were set to the starting area (that is, if the coordinates of the starting area were set to x:0, y:0).

The starting area is in no way related to pac-man. The lines are not all right angles, there is a timer, there's gravity, there are no aggressors, you're collecting coins instead of pellets.... Not every line maze is pac-man. This is an erroneous reference that should be removed. --[[Special:Contributions/198.41.235.167|198.41.235.167]] 17:16, 25 November 2015 (UTC)

Haven't read all the comments above so maybe someone has written about it?
If you click up it seems to count how many times. So it will just show white and then when you release again, it will take longer to hit the ground the longer you have pushed up. Tried with 100 clicks (9-10 seconds) and 200 clicks (20 seconds).
I got about 163 coins in about 15886 seconds. (4 hours and 24 minutes.) That was with breaks. It was written so shortly on the screen I did not manage to take it down for certain. But after that I read here about the 169 and found that there where at least three in the volcano I had not noticed at first. And it seems likely that there would be three more I have missed. But really fun to explore. I wrote a lot of the transcript along the way (not from the very start though) This I have now posted without any real order in the [[1608: Hoverboard/Transcript]] page.

The beret guy riding a torpedo (/explosive device of some sort) looks like a Dr. Strangeloe tribute to me.

Just added in the 'collision detection' section the text "On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile." To expand upon this, if this is a risk to anyone else (I'm reliant on mobile internet, being away from any comparable landline capability) then you need to look out for perfectly horizontal/vertical edges. For example, hovering up the side of the Washington monument and encountering (typically above the 'bricks' line) a completely flat top. Drifting onto that soon gets you embedded in the remaining Monument, somewhere well below the eventual tip. Alternately, drifting sideways over the landscape and discovering a perfectly vertical cliff downwards (just past the bowling pins is a prime location) tempts you to drift down it and then suddenly the solid land 'happens' around you, forcing a page-refresh and restart (though doubtless there's also various console tricks that could be used). The well, also 'opens out', but it's a lie. I've ended up trapped 'in white' below the now closed black blocks that surround the well bottom (and not found any way back up). But if there a 'texture' (like other cliffs) or 'slope' (like the real Monument edge) to the surface, you're probably Ok. It's a genuine surface or wall that you can generally navigate around without fear of being misled. (Or so is my experience.)

{{TOC}}

==Explanation==
{{incomplete|It's possible not all of the game's secrets have been unearthed yet.}}
The "comic" is actually a {{w|browser game}} made to celebrate the release of Randall's new book, ''Thing Explainer'', on the date of this comic's release.

The game features [[Cueball]] riding on a {{w|hoverboard}}. The only controls are the arrow keys. The player can jump repeatedly mid-jump to reach increasing heights. The player begins in a line-drawing maze with 17 gold coins located throughout and a "deposit" station. The ostensible goal of the game is to collect as many coins as possible and return them to the deposit in the fastest possible time, which returns a text message describing the result. Players consumed with obtaining the best possible time result for collecting the coins may not realize there is anything more to the game.

Beyond the maze on either side (just far enough that players who remain within the maze will not see) are tall walls seemingly designed to contain the player. However, the walls have a finite height and, combined with the ability to multi-jump, the player can leave the purported "play area" either to the sides or above the initial maze. This returns a flashing red error message "return to play area".

Outside the play area is an entire world to explore including are numerous points of interest and {{w|Easter egg (media)|Easter eggs}} similar in style to comic [[1110: Click and Drag]]. The larger game world is physically bounded in the left and the right direction, but is technically unbounded upwards and downwards, however, past a certain point there appears to be nothing interesting in the up or down direction. It could be possible that some unexplored hole leads deeper into the map than has been found so far, it is also possible that jumping for a considerable amount of time would allow the player to reach some additional content above the map. There are 152 more coins outside the initial "play area" for a total of 169 in the entire game.

===Technical aspects===
As previously noted, the comic bears considerable resemblance to [[1110: Click and Drag]]. The comic is made in much the same way, with 'drawn' images "glued" together to form a large "map", with the illusion of infinite bounds made possible through space saving techniques where blank tiles are not stored and are instead painted white. The boundary between blank squares and 'drawn' squares is made clear as any white space in the normal images has a very slight grey tint. Thus, seams between images and blank spaces can be discerned.

The tiles for the map are stored as simple PNG files in the naming scheme: X:Y+s.png. An example can be seen here: http://xkcd.com/1608/1013:-1096+s.png Each file is 513x513 pixels in size, one pixel is reserved as overlap to ensure seamless joining of images. So far, through experimentation, tiles in the range 928 to 1108 X and -1112 to -928 Y have been discovered, internally, the position of the player is divided by 512 and rounded down to give the position of the tile.

The collision map is encoded in the darkness of the black. Using an image manipulation program, one can easily find the secret pathways even in the zoomed out maps provided below by enhancing the contrast of the dark areas. On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile.

The game was made by [http://chromakode.com Max Goodman] who has previously worked on [[1416: Pixels]]. The source code for the game can be found [https://xkcd.com/1608/tigl.js here].

===Controls===
The keyboard controls are as follows:

* '''Go Left''' - Left arrow key, a or h
* '''Go Right''' - Right arrow key, d or l
* '''Go Up (jump or hover)''' - Up arrow key, w, or k
* '''Go Down (if gravity disabled)''' - Down arrow key, s, or j

This control scheme covers the three commonly used directional key sets: WASD a set of keys commonly used by modern games; HJKL a set of movement keys used by vi and applications which attempt to mimic vi key controls (vim); and the arrow keys, the most generic set of keys which is usually accepted by most applications which take movement as input, these were commonly used in older games.

On devices which have a touch screen and tilt sensor (portable devices like mobile phones and tablets) the controls are as follows:
* '''Go Left''' - Roll the device anticlockwise
* '''Go Right''' - Roll the device clockwise
* '''Go Up (jump or hover)''' - Tap the screen

After inspecting the source code, there appears to be no way to move down on a portable device, this is only relevant if gravity is disabled.

===Cheats and Exploits===
Aside from the obvious ability to move out of bounds in the game, there are some more obscure hidden features which can't be enabled through normal gameplay, the ones found so far are as follows:

'''Modes''' are activated by opening the Javascript Console (F12 [Or Command-Alt-I in most browsers under Mac OS X] to open Developer Tools, then Console tab) and writing corresponding commands:

* '''Gandalf Mode: ''' ''window.i.am.gandalf = true'' - jumps and runs further
* '''Speedhack: ''' ''explorer.opts.speed= *Value*'' - Speed hacking, with 1 = normal speed
* '''Jump Hack: ''' '' explorer.opts.jumpForce= -*Value*'' - Jump hacking, with -1 = normal jump (positive values cause the hoverboard guy to move down when jumping)
* '''Mewtwo mode: ''' ''window.mewtwo = true'' - disables gravity
* '''Noclip mode: ''' ''window.noclip = true'' - player is able to move around the map without collision. Combine with Gandalf and Mewtwo modes for free easy map traversal.
* '''Goggles mode: ''' ''window.ze.goggles()'' - displays a small window showing area around the player in a pixelated manner. The goggles indicate collision boundaries (where the player touches the world) in cyan lines. Black pixels that are passable (such as other characters or text) will be highlighted red (allowing secret passages to be discovered).
* '''Position Tracking: ''' ''window.explorer.pos'' - Returns the player location to the console. Can be used to track position and test to ensure you are still moving. Must be re-entered to compare positioning.
* '''Position Setting: ''' ''window.explorer.pos.x = *Value* or window.explorer.pos.y = *Value*'' - Can be used to manually set a position within the world. The start is at x: 512106, y: -549612. The left terrain bound is at x: 475210, y: -553711. The right terrain bound is at x: 567281, y: -549712. Mewtwo and Noclip modes are a must for exploring in this way.
* '''All the above: ''' ''window.explorer.opts'' - Contains all the game's parameters. You can directly mess with ''gravity'', collision (''disableCollision''), jump force (''jumpForce'') and speed (''maxSpeed''), among others. Run ''Object.keys(window.explorer.opts)'' to list all available parameters you can tweak.
* '''List all coins: ''' ''window.explorer.objects'' - Array containing the position of the 169 coins of the game.
* '''Disable tilt input: ''' ''getEventListeners(window)['deviceorientation'][0].remove()'' - on Macs with motion sensor, disables tilt input which causes problems controlling the avatar

'''Getting All Coins: ''' To instantly get all coins, input the below into the console window. Does not use standard formatting of [i] to avoid conflicts with window.i.am.gandalf

for (var T = 0; T < explorer.objects.length; T++) {
explorer.objects[T].got = true;
}

To teleport to the next coin every time you press the left or right arrow:

var T = 0;
document.onkeydown = function(event){
if (event.keyCode == 37) { T = T-1 }
else if (event.keyCode == 39) { T = T+1 }
else { return }
T = T % explorer.objects.length;
var coin = explorer.objects[T];
explorer.pos.x = coin.x1; explorer.pos.y = coin.y1;
}

For a quick tour of all the coins:

var delayInMilliseconds = 1000; // 1 second delay between each teleport. feel free to change this.
var index = 0;
explorer.objects.forEach(function(x){
setTimeout(function(){
explorer.pos.x = x.x1;
explorer.pos.y = x.y1;
x.got = true;
explorer.frame(); // forces a redraw
},
(index + 1) * delayInMilliseconds);
index++;
});

To see a list of coin coordinates you have not yet collected:

var L = 0;
for (var S = 0; S < explorer.objects.length; S++) {
var I = explorer.objects[S];
if (I.got) {
L++;
} else {
console.log(I.x1.toString() + ", " + I.y1.toString());
}
}
console.log("You've found " + L.toString() + " of 169 coins");

To display the distance and direction to the closest coin:

function distance(x1, y1, x2, y2) {
var dx = x2 - x1;
var dy = y2 - y1;
return Math.sqrt(dx * dx + dy * dy);
}

function angle(x1, y1, x2, y2) {
var dx = x2 - x1;
var dy = y2 - y1;
return Math.atan2(dy, dx) * 180 / Math.PI;
}

function renderRadar() {
var mindist = 10000000000;
var closest;
for (var S = 0; S < explorer.objects.length; S++) {
var I = explorer.objects[S];
if (!I.got) {
var dist = distance(explorer.pos.x, explorer.pos.y, I.x1, I.y1);
if (dist < mindist) {
mindist = dist;
closest = I;
}
}
}
var ang = angle(explorer.pos.x, explorer.pos.y, closest.x1, closest.y1);
var indicator = "";
if (ang > 112.5 || ang < -112.5) {
indicator += "left";
}
if (ang < 67.5 && ang > -67.5) {
indicator += "right";
}
if (ang > -157.5 && ang < -22.5) {
indicator += " up";
}
if (ang > 22.5 && ang < 157.5) {
indicator += " down";
}
document.getElementById("radar").innerHTML = "Distance: " + mindist.toFixed(1).toString() + " ";
document.getElementById("radar").innerHTML += indicator + " (" + -ang.toFixed(1).toString() + "°)";
document.getElementById("radar").innerHTML += "<div id='circle' style='border: 1px solid black; border-radius: 50px; width: 100px; height: 100px; position:absolute; top:50px; left:25px'/>";
document.getElementById("radar").innerHTML += "<div id='line' style='width: 50px; height: 1px; background-color: red; position:absolute; top:100px; left:75px; transform:rotate(" + ang + "deg); transform-origin:0% 0%'/>";
}

var d = document.createElement("div");
d.id = "radar";
d.style.position = "fixed";
d.style.left = "0px";
d.style.top = "0px";
d.style.width = "150px";
d.style.height = "160px";
d.style.border = "1px solid red";
d.style.zIndex = "2";
d.style.backgroundColor = "green";
d.style.color = "#8f8";
document.body.appendChild(d);

setInterval(renderRadar, 100);

To display your current coordinates:

function renderRadar2() {
document.getElementById("radar2").innerHTML = "x: " + explorer.pos.x.toFixed(1).toString() + " y: " + explorer.pos.y.toFixed(1).toString()
}

var d = document.createElement("div")
d.id = "radar2"
d.style.position = "fixed"
d.style.left = "150px"
d.style.top = "0px"
d.style.width = "150px"
d.style.height = "35px"
d.style.border = "1px solid red"
d.style.zIndex = "2"
d.style.backgroundColor = "green"
d.style.color = "#8f8"
document.body.appendChild(d)

setInterval(renderRadar2, 1000)

===Functionality===
By observing page code while playing, the game grabs and displays images based on location, and subsequently clears all non-visible images. The game uses what seems to be a position syntax to retrieve the intended images live, and returns an error if such an image does not exist, such as a blank area. This technically means things could be added to the world and updated live. If the player is moving sufficiently fast or if the internet connection is slow, this means that the player can get stuck in a black area that does not load in time.

This also means that the game does not have coded top or bottom limits, so any attempt to find the ''ceiling'' of the game will be futile unless the game is tweaked. The game does however have side limits.

When you deposit a certain number of coins, you will get one of the following messages:
* 0 coins : You got 0 coins in (n) seconds/ You successfully avoided all the coins.
* 1 coin : You got a single coin in (n) seconds/ It's a start.
* 2-4 coins : You got (n) coins in (n) seconds/ Not bad!
* 5-9 coins : You got (n) coins in (n) seconds/ Terrific!
* 17 coins : You got 17 coins in (n) seconds/ You found all the coins! Great job!
* 42 coins : You got 42 coins in (n) seconds/ No answers here.
* 169 coins : You got 169 coins in (n) seconds/ Are you Gandalf?
* All others: You got (n) coins in (n) seconds

Opening the console will display the text: what? hoverboard not enough for you!? in the log. Activating goggles mode will cause the text 'B-)' to appear in the log.

Leaving the play area will cause the red text 'RETURN TO THE PLAY AREA' to rapidly blink 3 times (150 msec duration), followed by a pause, and this will repeat 5 times for a total of 15 blinks. This will also reoccur if the player passes through the play area on their way back from exploring one side.

==Transcript==
:[This transcript only covers the starting page as shown on xkcd: {{xkcd|1608}}. A full transcript of the entire comic will be listed on a [[1608: Hoverboard/Transcript|separate page]].]

:[Cueball is shown on a hoverboard in the centre of the comic. Around him is a simple maze with 12 yellow coins. Another Cueball without howerboard is shown standing on one of the platforms to the right. The bottom half of the window is black. Right of where Cueball stands is a ramp. Behind the ramp is a computer. There is lots of space left of the maze, outside the maze. Text is only written in white below in the black area. The first part of the text is written below Cueball on howerboard. Then there is an arrow pointing to the computer and a label. Finally there is a line of text at the bottom of the black area.]

:[Under Cueball:]
:My new book,
:''Thing Explainer,''
:comes out today!
:To celebrate, here's
:a small game.

:[Under the arrow below the computer]
:Deposit coins here

:[At the bottom:]
:Use the arrow keys to move

:['''For the full transcript of the entire comic see [[1608: Hoverboard/Transcript]].''']

==Trivia==
* The alt text is only visible on the mobile version of the site, or when leaving the starting area. Further, when leaving the starting area, it shows different than normal alt text.
* If the focus switches from the game to the page, the cueball can freeze in midair. The same thing can happen if the window border overlaps the play area.
* The Washington monument has an invisible floor next to the visible bricks.

Currently there's nothing in the explanation of the titletext that addresses that Justice X is claiming to be ''either'' of two individuals, not even trying to properly impersonate a specific individual. Of course, logically, if they claimed to be a specific person then this specific person they claimed to be could so easily counter-claim. So that approach shouldn't work. But being vague would ''also'' be strange. Unlike a game of Mafia, when there might (occasionally) be reasons to be vague in this manner about one's role (and yet accept that this can look utterly Scummy, if this approach is directed at the Townies) to try to offset targetting by the opposing camp, this should ''still'' not work in a group where everyone already knows each other. So who knows how 'relatively illogical' the two approaches are, to each other... ;) But can anyone explain this better than me? [[Special:Contributions/162.158.152.5|162.158.152.5]] 11:32, 23 November 2015 (UTC)

Although there are nine justices, 10 votes were counted... it is possible that the mysterious tenth person voted along with the majority, and one of the original justices has voted against. The supreme court rarely votes unanimously on anything regardless of how reasonable the majority seems.[[User:Swordsmith|Swordsmith]] ([[User talk:Swordsmith|talk]]) 11:50, 23 November 2015 (UTC)
:Not sure where you're getting your information. For the 2014 term, fully 2/3 of the decisions decided were unanimous 9-0 decisions. The most common splits are 9-0 and 5-4. Most unanimous decisions are on smaller, less widely important matters. Larger more important and notable decisions are more likely to be concerned with a disagreement of law or interpretation and therefore to not be unanimous. [[Special:Contributions/108.162.216.48|108.162.216.48]] 14:32, 23 November 2015 (UTC)

Just a guess, but it could be in reference to [http://www.usatoday.com/story/news/politics/2015/11/20/obama-administration-appeals-immigration-ruling-supreme-court/76103084/ this article], where the nine represents the actual justices and the single is the President. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 14:35, 23 November 2015 (UTC)

In my opinion, "this guy" is the picture in the background. It looks like an emoticon with eyes/eyelids, eyebrows, and a nose. It seems to have two sides in balance, which could explain the Alito/Ginsburg reference.
[[User:Tlane|Tlane]] ([[User talk:Tlane|talk]]) 20:20, 23 November 2015 (UTC)
:That is the "scales of justice", a symbol of the weighing of arguments or the weighing of justice vs mercy, depending on the viewpoint. [[User:GonzoI|GonzoI]] ([[User talk:GonzoI|talk]]) 02:35, 24 November 2015 (UTC)

Also, the thing in the picture is a symbol representing justice. So it is "justice," but it is not "a justice." [[User:Tlane|Tlane]] ([[User talk:Tlane|talk]]) 23:16, 23 November 2015 (UTC)

[[User:Atreides]] has mentioned at [[1600: MarketWatch]] that identifying the newsreader as [[Ponytail]] is questionable, but if she is there, she should be here too. [[User:Markhurd|Mark Hurd]] ([[User talk:Markhurd|talk]]) 00:19, 24 November 2015 (UTC)
:It is not Ponytail either places, and I have corrected [[1600]]. She has no tail! But it is interesting that he uses the same appearance for a news presenter/newscaster in two comics so close. Maybe he has used her before? New character? We already have blonde character [[Miss Lenhart]]. But she was a teacher not a presenter... If anyone can find and collect more of these presenters it could be interesting. So far [[1607]] and [[1600]] are two very similar comics with same presenter! --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 14:58, 24 November 2015 (UTC)

It may be worth noting somewhere that not only are Alito and Ginsberg different genders, they also have very different judicial philosophies. A "surprisingly compelling" argument that the interloper could be either would make an interesting read simply because the two write very different opinions. [[User:Blaisepascal|Blaisepascal]] ([[User talk:Blaisepascal|talk]]) 23:08, 24 November 2015 (UTC)

I feel it's very shady still. "The supreme court ruled 9-1 ..." -- isn't that an admission that the 10th IS a justice? Because if he's not his vote should not be counted at all. [[Special:Contributions/199.27.129.101|199.27.129.101]] 01:30, 25 November 2015 (UTC)
:Pretty sure that's the joke.

Geeze... Some of y'all are totally overthinking this. [[User:WaltG123|WaltG123]] ([[User talk:WaltG123|talk]]) 05:45, 25 November 2015 (UTC)

I've never done this before but tell me where I'm wrong. A newscaster is reporting on the Supreme Court. She has the scales of justice in the background. She is talking about "this guy" who is apparently a tenth individual in addition to the nine justices. Normally a newscast would show the person being described, perhaps in the background behind the newscaster. In this case the scales have an emoticon-look with eyes/eyelids, a nose, and eyebrows, so they are like a face. That represents "this guy." The scales are in balance between two opposing sides, and as it turns out Alito and Ginsburg represent two opposing viewpoints on the court. Interestingly, the scales represent "justice" but the newsletter declares that they are not "a justice." There are other plays on words: how did "justice" get in here (to the Supreme Court), the Court does not know who justice is, all of the regular members seem to be voting against justice. [[User:Tlane|Tlane]] ([[User talk:Tlane|talk]]) 16:42, 25 November 2015 (UTC)
:Or it's just a joke about someone infiltrating the court & the USSC voting to determine if the person belongs there, with the scales pictured because Randall knows that:
:1) they're they symbol of the court
:2) there'd be no picture of this individual, as nobody knows who they are & cameras aren't allowed in the courtroom

:Anything can be complicated if you make it complicated. To quote Randall on this general subject: [http://spectralbovine.livejournal.com/184852.html "It was just the penis joke"] [[User:WaltG123|WaltG123]] ([[User talk:WaltG123|talk]]) 17:38, 25 November 2015 (UTC)
