1729: Migrating Geese

{{comic
| number = 1729
| date = September 5, 2016
| title = Migrating Geese
| image = migrating_geese.png
| titletext = "Hey guys! I have a great idea for a migration!" "Dammit, Kevin."
}}

==Explanation==
{{incomplete|Is there not some kind of slang on "Head Goose" that could relate to the fourth in line to the GB throne? Who are the three first in line to the throne? (both to be put in the table). More on the title text: "An idea for A migration?".}}
{{w|Bird migration|Migrating}} refers to the changing of a habitat, which happens every year with birds like {{w|geese}} that travel long distances to avoid cold seasons and get back to the food in the summer time. When geese fly to their new habitat, they tend to fly in a very clear {{w|V formation}}. The V formation improves the efficiency of flying birds, particularly over long migratory routes. All the birds except the first fly in the upwash from one of the wingtip vortices of the bird ahead. The upwash assists each bird except for the "leading" one in supporting its own weight in flight, saving them up to 20% of the energy needed.

It should be noted that geese do have family structures with adult geese in "alpha" positions, but not a strict ranking order. An individual's position in formation flights is coincidental and constantly changing, so that the goose at the point of the formation can pull back and rest in the V wings while others "lead" the swarm. Popular earlier beliefs about an "alpha goose" heading a formation for the entire flight is a myth, easily disproven by watching geese formations in flight.

This comic shows such a formation with 20 geese, with several geese and areas in the V formation labeled, giving different roles to the geese and assigning these areas a new meaning. See the [[#Table of labels|table below]].

Apart from a "twin engine" goose in the bottom right arm of the V the only part of the formation that would not normally be seen is Kevin, who flies off at a 45-degree angle. In that direction there is no aerodynamic help from the other birds, and in the title text the rest of the geese also exclaim, "Dammit, Kevin" when he (again?) tells them that he has a great new idea for a migration (maybe referring to the new direction).

===Table of labels===
{| class="wikitable"
!Name
!Explanation
|-
|Head Goose
(4th in line to the British throne)
|This goose may become the newest monarch of the UK, assuming the three who are further in line die. The current fourth in line to the British throne is {{w|HRH}} {{w|Princess Charlotte of Cambridge}}. In North America, the best-known goose migration is that of {{w|Canada goose|Canada geese}} to the US east coast. Canada used to be part of the {{w|British Empire}} and remains a member of the {{w|Commonwealth of Nations}}, so a "Canadian" goose would be well situated to stand within the succession.
|-
|Quarterback
|A {{w|quarterback}} is a position in {{w|American football}}, usually placed in the second row of an American football formation, just like the associated goose. On nearly every non-kicking play, the quarterback is the player who stands behind the center and receives the ball to start the play. In modern American football, the quarterback is usually considered the leader of the team, and is often responsible for calling the play.
|-
|Comptroller
|A {{w|comptroller}} is a position in a company. A comptroller oversees and manages all financial operations.
|-
|Migration abort goose
|This might be a reference to launch abort capsules used in rockets to safely land astronauts in the case of a critical stage failure. Or it could be operated like an abort button aborting the entire migration for all geese.
|-
|Twin-Engine Model
|This goose has two tails offset on each side of the center of the goose, instead of one tail in the middle like the rest. The "tails" also extend beyond the wings, which makes it look like a Twin-Engine aircraft, which has two motors: one on each wing instead of one in the nose.
|-
|CIA Informant
|A person, usually a criminal, that surreptitiously provides information to the {{w|Central Intelligence Agency}} (CIA). If these geese are from Canada, the CIA might have inserted an informant to be kept up to date on their activities.
|-
|Backups
|These are geese that are not used in the formation so they can replace other geese in their positions in case they have problems performing their task. This may also be a pun/joke about technology/data "migrations" where backups should be taken liberally due to risk of data loss.
|-
|Shock Front
| A shock front is the front boundary of a {{w|shock wave}} created by either a {{w|sonic boom}} or another explosion in a fluid/gas. It can also refer to the shock wave itself. It usually only happens when such violent events occur, and would thus not be present in front of "normally" migrating geese. But of course this set of geese may be somewhat different with the involvement of CIA and stealth technology.
|-
|Missing Valence Geese
|In Chemistry, {{w|Valence (chemistry)|valence}} electrons are the electrons in the outermost "layer" which change places when chemical reactions happen. As there is an optimal number of electrons in a layer, if there are missing valence electrons, atoms which can fill in these gaps tend to react with the atoms having the missing electrons. In case of "electron sharing" (aka covalent bond) molecules result from such an encounter. The comic suggests a second geese formation that has proper "valence geese" in the appropriate position could bond (=merge) with this one into a larger formation. A normal geese V formation like the one in the comic has one side longer than the other and this is possibly Randall's explanation for the phenomenon.
In reality, geese do form V-shaped flocks, since the rear geese can profit aerodynamically from the vortices created by the front geese, and that way the overall flock requires less energy. So there is actually some evolutionary sense for additional geese to fill the "valence holes". It is thus a little weird that there are two backup geese close to these valence vacancies, as they should then have filled them up...
|-
|Stealth cargo being escorted
|The formation is forming a protective surrounding around an empty space in the middle which in a military formation could contain protected cargo. As there is no cargo visible in the geese formation, it is titled "{{w|Stealth technology|stealth}}". This would be a nice [[:Category:Conspiracy theory|conspiracy theory]] to spread.
|-
|Kevin
|Also mentioned in the title text. It is unclear what the name refers to. It may refer to:
* The "go-to name" for [[Randall]] at the time of this comic's release, as he also used the name in [[1719: Superzoom]], ten comics before this one.
* An {{w|Eddie Izzard}} skit about migrating birds (Eddie Izzard - Religions, Cats & Migrating Birds). A group of birds are following Kevin, assuming that he knows where he is going. But he is lost and they end up in the wrong place.
* Kevin McCallister from the {{w|Home Alone}} movies, who gets separated from his parents a lot. (see [[1164: Home Alone]]).
* [https://www.reddit.com/r/AskReddit/comments/219w2o/whos_the_dumbest_person_youve_ever_met/cgbhkwp Kevin of reddit fame], the dumbest person ever.
* One of the {{w|Minions (Despicable Me)|Minions}} from the "{{w|Despicable Me}}" franchise ([http://despicableme.wikia.com/wiki/Kevin Kevin]), who leaves the main Minion group in search of a new master.
* The intelligent and playful bird [http://disney.wikia.com/wiki/Kevin Kevin], from the Disney/Pixar movie {{w|Up (movie)|Up}}.
* [https://youtu.be/OyqdoxTEmdg Kevin] from {{w|South Park}}. Especially the "Dammit Kevin" mentioned in the title text could arise from this.
* [http://the321penguins.wikia.com/wiki/Kevin Kevin] from [https://en.wikipedia.org/wiki/3-2-1_Penguins! 3-2-1 Penguins!], who "will answer questions and save planets without even knowing he could."
* {{w|We Need to Talk About Kevin}}, a book and drama film about a deranged child.
* Kevin Beckman, the dimwitted receptionist from the 2016 [https://en.wikipedia.org/wiki/Ghostbusters:_Answer_the_Call Ghostbusters] movie.
* Just a random name, as the only of the birds that actually has a personal name acts alone instead of following the other birds.

:Understanding Migration of Geese

:[20 geese are shown flying in a typical migratory V-formation. As they are shown in silhouette it is not possible to determine if they are seen from above or from below. They are flying toward the top of the image with the first goose close to the top in the middle of the image. There is one head goose, and then there are 7 geese in the left arms and 9 geese in the right arm. Behind the left arm there are two stragglers that are not in line with the others, but closer to the middle than those above and not as close to each other as the rest but still flying in the same direction. Finally there is one goose at the bottom right corner flying at a 45 degree angle away from the other to the right. The first goose is flapping its wing, which is also the case with six other geese, no. 4 and 6 in the left and 3, 5 and 6 in the right arm as well as the middle of the two in the rear towards the middle. The rest are soaring with straight wings and all of these look the same except no. 7 in the right arm which has two tails, which both goes ahead of the wings, making it look like a plane with two engines. The head goose and 5 of the 9 geese in the right arm as well as the one bottom right are labelled with and arrow pointing to them from the label. The front goose has the label in front to the left, the other have it in front to the right, except the second last in the arm which has the label inside the V and one flying away which has the label right above it. The two behind and right of the left arm have one label behind them with two arrows from the label pointing at both geese. There is a thick curvy line in front of geese no. 3 to 5 in the left arm. In front of that line is a thinner broken line. In front of this is a label written with the same curvature. There are two areas surrounded by dotted lines. The first one is behind the last of the left arms geese, extending in the same direction for a distance of about two geese. It has a label above and left with and arrow pointing to it. The other area is in the middle of the V forming a loose triangular structure with a label inside.]

Talk:1724: Proofs

2016-08-27T02:25:25Z

108.162.218.185:

Judging from my experience when I first encountered proofs in math classes (or my general experience from math classes), the teacher is going to write down a "proof" which makes absolutely no sense to students and is also never explained in a way that actually makes them understand. Instead, they are just going to use "dark magic" and write what seems to be completely senseless to students.
[[Special:Contributions/141.101.91.223|141.101.91.223]] 04:24, 24 August 2016 (UTC)
:: 'Dark magic' might also refer to the supernatural, so when the teacher said that an answer 'will be written' in a specific location, Cueball took this to mean that a spirit would be summoned to write it, like a ouija chalk board.

Chip in there if you have any opinions on that regard... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:01, 24 August 2016 (UTC)

Irrationality proof isn't really a proof by contradiction (it doesn't use double negation elimination). You're showing (exists a,b. ...) -> False by assuming (exists a, b. ...) and showing False, which is implication introduction --[[Special:Contributions/162.158.85.105|162.158.85.105]] 07:33, 24 August 2016 (UTC)

I'm thinking she's doing one of those proof that write down a formula or function out of nowhere, and proceeds to proof everything with it. [[Special:Contributions/108.162.222.125|108.162.222.125]] 08:43, 24 August 2016 (UTC)

This comic reminds me of "divination" rituals, where a magical spirit is summoned to write out an answer. Usually not something as complex as here, but hey, XKCD! --[[User:Henke37|Henke37]] ([[User talk:Henke37|talk]]) 10:04, 24 August 2016 (UTC)

Man, Reductio ad absurdum never made any logic. If we could assume any thing, why use logic?
Oh wait, it has already been covered in XKCD {{unsigned ip|162.158.49.12}}

"Dark magic" proofs are centered around properties of functions, and abstract concepts, rather than manipulating the functions themselves?? [[Special:Contributions/108.162.246.113|108.162.246.113]] 11:26, 24 August 2016 (UTC)

My assumptions is that the "Dark Magic" being referred to here is more "A technique that works, though nobody really understands why." [see http://catb.org/jargon/html/B/black-magic.html] In this case, the teacher is setting up a proof in an manner which will lead to the desired goal, but to the student it is exceedingly unobvious as to why one would do it this way, other than "it works" [[Special:Contributions/108.162.219.52|108.162.219.52]] 15:30, 24 August 2016 (UTC)

I was thinking that a "dark magic proof" referred to those ridiculous "party trick" proofs like 'proving' that 1 = 0 via some confusing train of logic, and mathematical sleight of hand. {{unsigned ip|108.162.237.213}}

Maybe he meant "dark patterns"? {{unsigned ip|162.158.126.139}}

It seems pretty obvious to me that by "weird, dark magic proofs", the student is talking about proofs that drag in far-flung reaches of mathematics so distant that they no longer appear to be mathematics, especially ones that involve meta-reasoning. Gödel's proof of the incompleteness of Peano arithmetic is the archetypical example, but others include Lob's theorem and any proof by contradiction involving the halting problem. Ms Lenhart's proof starts out by setting up a proof-by-contradiction, already a warning sign, and she then escalates it at the end by implying that this proof will somehow involve the actual physics of where the solution can and cannot be written. [[Special:Contributions/108.162.241.123|108.162.241.123]] 17:27, 24 August 2016 (UTC)

:: Agreed, although I think starting out with a proof by contradiction setup is by itself not that much of a warning sign. However it heads straight into meta-space by making the assumption of the existence of a function that produces a solution of something. [[User:Zmatt|Zmatt]] ([[User talk:Zmatt|talk]]) 18:52, 24 August 2016 (UTC)

:: The fact that the proof mentions the actual blackboard on which it is written is of course problematic in numerous ways, as is predicating on whether something "will eventually" happen. This is well outside the scope of the [https://en.wikipedia.org/wiki/Zermelo–Fraenkel_set_theory usual mathematical foundations]. Since careless use of meta-recursion is a [https://en.wikipedia.org/wiki/Curry's_paradox trap], such a proof would have to very very carefully consider foundational issues and cannot handwave over them.

"''In the title text the decision of whether to take the axiom of choice is made by a deterministic process. The axiom of determinacy is incompatible with the axiom of choice...''" The axiom of determinacy is not really relevant to deterministic processes - it is about (certain types of two-players-) games and says that any such game is determined (that is, some player has a winning strategy). So this axiom is not relevant to the title text --[[Special:Contributions/162.158.83.66|162.158.83.66]] 17:39, 24 August 2016 (UTC)
:I agree. I read the title text in almost exactly the opposite way - that the proof relies on the existence of a deterministic process for selecting objects, and therefore the invocation of the axiom of choice as a part of the process is superfluous (but not a contradiction). Anyhow, the axiom of determinacy isn't ever mentioned, so it probably shouldn't be shoehorned in here. [[Special:Contributions/162.158.74.53|162.158.74.53]] 20:36, 24 August 2016 (UTC)

I feel like it is a stretch to assert Lenhart is setting up a proof by contradiction. It sounded to me more like an prior knowledge proof (not sure it's technical name). For example, "calculate the space between two concentric circles of differing diameter when the longest straight line you can draw is length d." If you assume there is a function F(r1, r2) which has been previously proven to calculate this space, then it is easy to show that the space is in fact .5*pi*(.5*d)^2 (as you have a degenerative case where r1=0, and you have an ordinary circle). I also think this type of proof is more "dark magic"-feeling than a simple proof by contradiction. {{unsigned ip|108.162.216.87}}

:While technically the same pattern, I would assume something more like NP-complete proofs: Assume we have function F which solves this problem in polynomial time ... then we can solve that problem in polynomial time as well. Just, instead of "polynomial time", the existence of function is the question here, so it will likely be something around {{w|Recursively enumerable set|recursively enumerable}}/{{w|countable set|countable}} stuff. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 13:02, 25 August 2016 (UTC)

I don't like how this explanation uses the word "standard". Non-standard mathematical objects are subjects of non-standard analysis, not metamathematics. --[[Special:Contributions/108.162.218.185|108.162.218.185]] 02:25, 27 August 2016 (UTC)

Saying that everything ends up in "philosophy" is simply choosing from a long list of possible entries to suit an argument. I found it much more interesting, having gotten to philosophy, to keep going through the loop, then to see where certain pages drop you into said loop. The loop currenty is reality, existence, world, human, hominini, tribe, biology, natural science, sciences, knowledge, fact, proof, necessity and sufficiency, logic, reason, consciousness, quality (philosophy), property (philosophy), modern philosophy, then finally philosophy. It's as if we've stumbled upon a new classification of knowledge. If only we could look recursively at ALL the things that lead into a certain topic in the loop. For example, goat drops you into the loop at biology, which makes perfect sense, but Volvo drops you in at natural sciences from a very convoluted path which includes physics, time, dimension, list of time periods, and scandinavia. In other words, it's the journey not the destination that I find interesting. - naginalf [[Special:Contributions/108.162.216.40|108.162.216.40]] 15:39, 12 March 2014 (UTC)

Randall is either mistaken or intentionally misinformative (or rather, politically correct) in his IQ estimates. What's a car hyperbole aside, the cluelessness, sentence length, and spelling of the outage-messages remind of a person in their low 90s-high 80s, if not lower, and Randall is clearly more than 120, (conservative) average for physics majors as it might be.

;What can we learn?
I've learned that memorizing facts is so yesteryear. Over next few years facts will be even easier to find, understand, use, reference and forget. When in school we should concentrate not on memorizing facts we can look up later, but rather new methods to think outside the box full of facts others placed inside it. (Thank you Mr. XKCD) - [[User:E-inspired|E-inspired]] ([[User talk:E-inspired|talk]]) 13:42, 28 February 2013 (UTC)
: That is true, but the overhead for looking something up versus remembering it is usually great enough that memorizing some things (multiplication tables come to mind) can increase the speed we can arrive at conclusions, or can give us other options (correlation between spark plug gapping and engine performance) that might not have come to mind otherwise. Outside of that, even though we forget much of it, having a vague sense of things (dates, locations/countries, etc) allow us to start out knowing at least something (order of things that occurred, Egypt being in Africa, Pythagorean theorem). This is just my opinion, and I may be biased, since I like facts. [[User:Tryc|Tryc]] ([[User talk:Tryc|talk]]) 13:19, 25 July 2013 (UTC)

Yeah, I hit a loop on the page Community. Went right from National community to Community again. {{unsigned|69.91.105.111}}

These infinite loops seem to be 'fixed', I went through fact and other stuff right to philosophy.{{unsigned|141.35.48.11}}

Another loop is "England". It goes right to "Countries of the United Kingdom" which returns immediately to England.

Finally we all end up in {{w|Reality}}. [[Special:Contributions/85.178.28.173|85.178.28.173]] 21:16, 29 May 2013 (UTC)

I do have to say that the best loop that doesn't feed to Philosophy is {{w|Sand Fence}} and {{w|Snow Fence}}. The first sentence of each article is identical except for switching the instances of sand and snow. --[[Special:Contributions/68.97.21.122|68.97.21.122]] 05:17, 6 July 2013 (UTC)

Saying that everything ends up in "philosophy" is simply choosing from a long list of possible entries to suit an argument. I found it much more interesting, having gotten to philosophy, to keep going through the loop, then to see where certain pages drop you into said loop. The loop currenty is reality, existence, world, human, hominini, tribe, biology, natural science, sciences, knowledge, fact, proof, necessity and sufficiency, logic, reason, consciousness, quality (philosophy), property (philosophy), modern philosophy, then finally philosophy. It's as if we've stumbled upon a new classification of knowledge. If only we could look recursively at ALL the things that lead into a certain topic in the loop. For example, goat drops you into the loop at biology, which makes perfect sense, but Volvo drops you in at natural sciences from a very convoluted path which includes physics, time, dimension, list of time periods, and scandinavia. In other words, it's the journey not the destination that I find interesting. - naginalf [[Special:Contributions/108.162.216.40|108.162.216.40]] 15:39, 12 March 2014 (UTC)

Randall is either mistaken or intentionally misinformative (or rather, politically correct) in his IQ estimates. What's a car hyperbole aside, the cluelessness, sentence length, and spelling of the outage-messages remind of a person in their low 90s-high 80s, if not lower, and Randall is clearly more than 120, (conservative) average for physics majors as it might be.

;What can we learn?
I've learned that memorizing facts is so yesteryear. Over next few years facts will be even easier to find, understand, use, reference and forget. When in school we should concentrate not on memorizing facts we can look up later, but rather new methods to think outside the box full of facts others placed inside it. (Thank you Mr. XKCD) - [[User:E-inspired|E-inspired]] ([[User talk:E-inspired|talk]]) 13:42, 28 February 2013 (UTC)
: That is true, but the overhead for looking something up versus remembering it is usually great enough that memorizing some things (multiplication tables come to mind) can increase the speed we can arrive at conclusions, or can give us other options (correlation between spark plug gapping and engine performance) that might not have come to mind otherwise. Outside of that, even though we forget much of it, having a vague sense of things (dates, locations/countries, etc) allow us to start out knowing at least something (order of things that occurred, Egypt being in Africa, Pythagorean theorem). This is just my opinion, and I may be biased, since I like facts. [[User:Tryc|Tryc]] ([[User talk:Tryc|talk]]) 13:19, 25 July 2013 (UTC)

1608: Hoverboard

**[http://1101b.com/xkcd1608/ fully zoomable map w/ toggleable coins and passages] - courtesy of [https://www.reddit.com/user/lanzaa lanzaa] on the same reddit [https://www.reddit.com/r/xkcd/comments/3u4sy1/xkcd_1608_hoverboard/cxbyn86 thread]

{{TOC}}

==Explanation==
{{incomplete|Layout of this explanation needs revision. Expanation of all items of interest with pictures like in [[1110]].}}
The "comic" is actually a {{w|browser game}} made to celebrate the release of [[Randall|Randall's]] new book, ''[[Thing Explainer]]'', which was released on the same day as this comic (November 24th 2015). The comic appeared on a Tuesday, replacing that week's normal Wednesday release.

The game features [[Cueball]] riding on a {{w|hoverboard}}. The only controls are the left, up, and right arrows. Alternatively you can use the A, W, and D keys or the H, K, and L keys, corresponding to left, jump, and right, respectively. On mobile the controls are replaced by tilting the phone left and right to move and tapping the screen to jump.. 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 numerous points of interest and {{w|Easter egg (media)|Easter eggs}} similar in style to comic [[1110: Click and Drag]]. There are even more coins to collect. The larger game world is physically bounded in the left, right, and up directions, with invisible walls on all three sides. The upwards invisible wall is tough to pinpoint; although [[Cueball]] appears to continue upwards, once the jump button is released, he will continue to look upwards as if continuously jumping; in addition, the longer the up arrow is pressed repeatedly, the longer it will take for [[Cueball]] to fall down again once the button is depressed. In principle it may also be unbounded in the downwards direction, but there are only a few places you can "sink" into the ground/water/lava, and here you cannot go down indefinitely. It could be possible that there could be some unexplored parts of the map, but given the map is already made this seems unlikely. There are 152 more coins outside the initial "play area" for a total of 169 in the entire game.

===Messages in the starting area===
*Different amounts of coins collected in the play area, will give different messages in yellow on the black part at the bottom of the screen when delivered to the coin collector.
*Below is a table with examples of what may be written depending on the number of coins. The time (and the amount when there is a range with similar rating) is just chosen at random (although in a realistic range). To get above 17 you of course have to leave the play area and come back again...
**In chrome and firefox there is not message for those above 9 coins, except 17, 42 and 169. But in Internet Explorer there is still a message for those cases: "Undefined".
**See [[1608: Hoverboard/Screen-shots#Coin collecting messages|screen-shots]].

*Once you leave the area you get a [[1608:_Hoverboard/Screen-shots#Return_to_the_play_area|flashing warning message]] in red letters at the bottom of the screen:
:{| class="wikitable"
|style="background-color:black;"| '''Return to the play area'''
|}
*This message flashes three times over 1.2 seconds (the message only disappears for about 150 ms each time)
*Then there is a pause for about 1.3 seconds and then this repeats for a total of 5 repetitions, a total of 15 flashes in just about 11.3 second seconds.
*The message will stop immediately if you re-enter the play area during this period.
*If you re-enter later it will flash once you leave again.
*For the program the play area is anything within and below the walls just outside the maze you start in.
**More precisely you first leave the play area if you pass over the middle part at the top of the walls
**Or if you make one jump from standing on top of the walls.

This is probably a reference to a part of Orson Scott Card's "Xenocide" in his Ender series. In it, the main character, Ender, visits a hive queen "bugger" he saved on his travels and became friends with, at a time after the queen has settled in on a new planet. At one point, Ender brings other humans to meet the queen at a time when she was giving birth to some of her drones. This is most likely meant to represent a parody of that conversation or else represent a comedic idea of his first conversation with her when she had been birthing, where Ender is alone and is speaking to the Hive Queen. In this version, when he finds out that she is in the process of birthing more ants, rather than being compassionate and understanding with the Queen(as he is in the book), Ender is weirded out like the other humans he brings along with him later.

===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].

*An [http://www.explainxkcd.com/wiki/images/9/92/thumb_1608.jpg incomplete compilation] of the entire game area (note the missing pinnacle of the Washington Monument. It also missed the floating island above the monument).

===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.

===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.

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.

==Transcript==
:[This transcript only covers the starting page as shown on xkcd: {{xkcd|1608}}. There is also an [https://xkcd.com/1608/info.0.json official transcript] on xkcd. But on Explain xkcd these{{xkcd}} transcripts are not used. This transcript covers what is on the first image you see when opening the comic on xkcd. 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 terminal. 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 hoverboard. Then there is an arrow pointing to the terminal 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

==Trivia==
*There is as usual [[:Category:No title text|no title text]] for these interactive comics. But there is actually one listed in the [http://xkcd.com/1608/info.0.json info page] on xkcd. But this text: "Return to the play area", is never shown as a normal title text. But it will erroneously be shown in the unofficial mobile versions of the site.
**This is actually the text that is shown blinking red at the buttom of the screen when leaving the starting area.
*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 which you can enter from further up the monument.
**You can also just walk through the monument at its base as shown by the sign.

===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. Click to expand:

<div class="mw-collapsible mw-collapsed leftAlign" style="width:100%">
 
*'''Gandalf Mode:''' ''i.am.gandalf = true'' - jumps and runs further. displays a white gandalf hat that works well in places where the avatar can't be seen.
*'''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:''' ''mewtwo = true'' - disables gravity
*'''Noclip mode:''' ''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:''' ''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:''' ''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:''' ''explorer.pos.x = *Value* or 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:''' ''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(explorer.opts)'' to list all available parameters you can tweak.
* '''List all coins:''' ''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 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 (with inverted colors once you have all the coins):

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 = {
x1:512278.0, y1:-549613.0
};
var linecolor = "red";
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;
}
}
}
if (mindist == 10000000000) {
mindist = distance(explorer.pos.x, explorer.pos.y, closest.x1, closest.y1);
if (document.getElementById("radar").style.backgroundColor != "red") {
document.getElementById("radar").style.backgroundColor = "red";
}
linecolor = "green";
} else {

}
}
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: " + linecolor + "; 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.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)

Talk:1608: Hoverboard

2015-11-30T19:17:14Z

108.162.218.185:

Well, this will be the next incomplete explanation for a while. -[[Special:Contributions/162.158.90.165|162.158.90.165]] 21:58, 24 November 2015 (UTC)

Yes, one thing to note is how to get the hell out of the cave near the volcano [[Special:Contributions/108.162.249.159|108.162.249.159]] 22:38, 24 November 2015 (UTC)

The image is made up of small images with addresses of the form http://xkcd.com/1608/XXXX:-YYYY+s.png (although not every coordinate inside the bounds has an image associated). A script could probably dump out all the images and paste them together. --[[Special:Contributions/108.162.216.6|108.162.216.6]] 22:46, 24 November 2015 (UTC)

West -- Under Lava Pools -- Elon Musk's Secret Volcano Base (not as enjoyable as you might expect).

The Starship out east contains, among other things, Darth Vader, apparently explaining Steven Universe to a subordinate. (Steven and the Crystal Gems can be found a the west end of the ship, near an ice cream cooler.) The same ship contains an elaborate homage to the original Prince of Persia. {{unsigned ip|162.158.56.5}}

There, have at thee an image! [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 22:58, 24 November 2015 (UTC)

There are 168 coins spread throughout the map according to the source code [[Special:Contributions/173.245.54.53|173.245.54.53]] 23:03, 24 November 2015 (UTC)

When using a device, instead of saying "use arrow keys to move", it says "tilt to move, tap to jump". It's also a lot harder to control. {{unsigned ip|108.162.250.159}}

It's actually 169 coins (t.length). --[[Special:Contributions/188.114.111.129|188.114.111.129]] 23:22, 24 November 2015 (UTC)

I got 153 coins!! :D There's two starships, one's a star destroyer with an expansive maze dropping regular torpedoes on the other. May be noteworthy that there are various references to Star Wars and Steven Universe throughout. [[Special:Contributions/108.162.221.13|108.162.221.13]] 23:27, 24 November 2015 (UTC)

The second starship is the TantiveIV, Leia's ship at the beginning of episode 4. Note directly below the Tantive, the terrain seems to be sand dunes. Also there are two more space ships by the volcano; an X-wing at a gas station and an Apollo Command Module. {{unsigned ip|108.162.216.24}}

https://xkcd.com/1608/tigl.js - Looks like there's an easier to read version of the code there. Maybe that'll help someone with extracting all the images. {{unsigned ip|

I've got all the images downloaded. Zipping/uploading now. Should I post a link here when complete or what's the best way to share these? I'm also working on setting up a zoomable map. [[Special:Contributions/173.245.54.53|173.245.54.53]] 23:57, 24 November 2015 (UTC)

The collision detection is glitchy. I keep landing/bumping against platforms I'm far away from. Is getting stuck against walls normal? --[[Special:Contributions/199.27.130.234|199.27.130.234]] 00:01, 25 November 2015 (UTC)

Tiles are located here in a zip: https://up1.ca/#Gi51KPFyPRELe0T1D6q9Mw All I did was iterate over http://xkcd.com/1608/X:-Y+s.png from X=[916...1116] and Y=[916...1116]. I'm working on putting a zoomable map together. If anyone has interest in helping we could hop on IRC? [[User:Jcox|Jcox]] ([[User talk:Jcox|talk]]) 00:15, 25 November 2015 (UTC)

I've written a zsh script to iterate over all possible tiles (does anyone know the height limits? the source only gives the left and right limits) and glue them together into one giant file. I'll upload the results as soon as it's finished. [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 00:17, 25 November 2015 (UTC)

I don't think it's limited vertically at all. I found a zoomable map on the reddit topic http://codepen.io/KyleDavidE/full/605dc87b614ff6b2bd716f4c6f640203/ (by kyledavide) [[User:Miraries|Miraries]] ([[User talk:Miraries|talk]]) 00:21, 25 November 2015 (UTC)Mirages

Here's a zoomed out map of all the game area: https://i.imgur.com/rNU9ZgN.png. From ''luke_in_the_sky'' at Reddit [https://www.reddit.com/r/xkcd/comments/3u4sy1/xkcd_1608_hoverboard/cxc1245]. --[[Special:Contributions/188.114.111.129|188.114.111.129]] 00:35, 25 November 2015 (UTC)

Alright, the full png of the entire map is almost finished, I should have used white tiles as blank tiles but I guess I can fix that up in gimp, and I'm not sure how to account for the 1 pixel overlap with just imagemagick convert. The last step is to merge allthe layer images into one giant image, wish my laptop the best of luck! [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 01:00, 25 November 2015 (UTC)

Someone beat you to it, but keep on it: that one doesn't have right limit tiles. https://www.reddit.com/r/xkcd/comments/3u4sy1/xkcd_1608_hoverboard/cxc0p8x --[[Special:Contributions/188.114.111.129|188.114.111.129]] 01:19, 25 November 2015 (UTC)

Perhaps we can change the screenshot at the top to this? It's a quickly hacked overview of the entire map: http://imgur.com/Mz9arHz [[Special:Contributions/199.27.129.167|199.27.129.167]] 01:27, 25 November 2015 (UTC)

I got 159 coins without the map. If you guys are still wondering how to escape the volcano, move to the right for as long as you think you can, then start spamming the up key while switching between holding the left and right keys. It worked for me on my first try.[[Special:Contributions/162.158.252.119|162.158.252.119]] 07:06, 25 November 2015 (UTC)

Didn't take down the coordinates, but the layout to the first level of the original Prince of Persia is in there, including the guard standing by with his scimitar! I found it in the ship atop the pyramid east of the play area. --[[Special:Contributions/108.162.218.245|108.162.218.245]] 06:24, 25 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}}
: It actually returns a 1 by 1 pixel white GIF. [[User:Arch-TK|Arch-TK]] ([[User talk:Arch-TK|talk]]) 13:14, 25 November 2015 (UTC)

Is there a way that we can merge the "game" part of this comic with the map of [[1110: Click and Drag]]? Allowing us to explore that one in a similar way? [[User:Bon|Bon]] ([[User talk:Bon|talk]]) 11:03, 25 November 2015 (UTC)

Well I managed to find (nearly) everything, except the floating rock island, and 162 coins without the map, but even with looking at several maps, I didn't pass any graveyard nor found the way to the grey ocean, which I assume is underneath the "continent". Does anyone know where the entrance is? [[Special:Contributions/162.158.90.218|162.158.90.218]] 11:54, 25 November 2015 (UTC)

Just thought I should say; the comic supports some alternative movement controls, there's the arrow keys, WASD, and also the vi keys (hjkl), and the numpad (8426). [[Special:Contributions/108.162.242.125|108.162.242.125]] 13:29, 25 November 2015 (UTC)

I was not able to get to some points because they were surrounded by text, people or other objects. Is that normal, or are there tricks to get to every coin without using cheats (console)? It would be nice if this could be mention / explained in the article. [[Special:Contributions/162.158.135.35|162.158.135.35]] 13:31, 25 November 2015 (UTC)
:In some cases you can come in from the side as opposed to trying to come down through or up through something. Example: at the X-Wing "gas station", to get that coin, land on the ground to the left of the X-Wing and move to the right on the ground towards the gas station. [[User:Jarod997|Jarod997]] ([[User talk:Jarod997|talk]]) 14:45, 25 November 2015 (UTC)

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). What is the reason for the very large numbers? --[[User:BlueMoonlet|BlueMoonlet]] ([[User talk:BlueMoonlet|talk]]) 15:50, 25 November 2015 (UTC)
: The large numbers are the actual ones used by the game code and displayed by the hacked-up "radar" so it was a natural choice to use them as they are.

I would personally work on de-obfuscating the full source code using the fragment found there but technically the source is covered by implicit copyright laws and that means that if I published a derived work I would be breaking those laws. Should I just change the line from "The source code can be found at ..." to "The full (obfuscated) source code can be found at ...tigl.min.js and a deobfuscated piece of the source code can be found at ...tigl.js".

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. Hope fully a full and useful transcript can emerge from this. I hope my text can be used if not used as it is written at the moment.--[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 02:05, 26 November 2015 (UTC)

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)

I'm trying to find a game that I played on the computer about 2 years ago. I remember that you could see the entire play area the entire time. It was timed. The object was to get to a hole (maybe blue in color) to end the level. There were blocks that often blocked your path, which you needed to push out of your way or more often use them to make bridges to cross water. Some of the levels were very much a timing game where you needed to quickly move a block through a winding path(up, down, left, right only)to avoid being caught by, I believe, moving blocks.The closest screen shot that I've found is Chips Challenge, which is not the game that I played previously.
