==Explanation==
In the same vein (and with the same humor) as the [[:Category:xkcd Phones|xkcd Phone series]], the XKeyboarCD seems to be an overly inventive and borderline ludicrous keyboard intended for some unknown audience. It has an assortment of features (some fairly normal, some more exotic) which give it a..."diverse skill set". This may be in reference to {{w|Space-cadet keyboard}}s which were made for programmers and had several keys not present on standard QWERTY keyboards.

XKeyboarCD is a play on xkcd, and keyboard. (XK eyboar CD)

*'''54 Configurable Rubik's Keys'''
The smaller cubes on a {{w|Rubik's cube}} resemble computer keys, so this feature makes fun of that by adding a spinnable Rubik's cube above the keyboard. The implication is that the keys would be 'configured' by twisting the sides of the cube until the desired configuration is reached, although parity means that not all configurations could be reached by conventional means by a 3x3 cube. (Parity exists on 4x4 cubes.) There can be a maximum of 53 keys (the bottom center position can't contain a key because it's the mounting position). Additionally, the top key can't be moved around, so the maximum amount of configurable keys is 52. (The four remaining centers can be moved by rotating the entire cube.) The bottom-facing keys would obviously be hard to see/reach.

*'''Hardcoded Plastic Keys for the 5 Most Useful Emoji'''
This feature parodies the feature of some laptop-keyboards where it is possible to dynamically assign emojis to a small touchscreen area. There is a disaccord between hard-coded, useful and emoji, especially with the large keys in a central position on the keyboard. Which emojis would be "the most useful" is highly subjective. For example in the comic it shows the quite popular laughing with tears emoji, along with the octopus emoji and others. Notably, the "aerial tramway" was once the least-used emoji, and remains very rarely used.

*'''Serif Lock'''
{{w|Serifs}} are small lines on the ends of certain characters in fonts such as Times New Roman and Georgia. It is dependent on the font, not on the character; "A" is represented by the same code regardless of its font. Since a given font almost always either has or doesn't have serifs, this key seems challenging to implement. This key could be implemented, however, by simply changing between a pair of fonts when it is pressed. What's more, the button is placed roughly where left shift is on most keyboards, liable to cause frustration.

*'''Unlimited Key Travel'''
Key travel is the distance a key moves between its unpressed and pressed states. In reality, laptop keys only move a few millimeters before bottoming out, and conventional keyboards up to about a centimeter. Increased key travel may make typing more comfortable, up to a point. However, the usefulness of having unlimited key travel is unclear, and the question of how this would be physically possible in the keyboard depicted remains unanswered. The keyboard would have to be infinitely deep to allow unlimited key travel, although pushing it to the near bottom would require extra-long fingers. At least it is the greatest possible value, trumping any other keyboard. This is a play on transport passes, allowing unlimited travel (usually within a certain time or transport network).

*'''Diagonal Spacebar'''
Instead of a wide key at the bottom that typists can hit easily with either thumb, we now have a tall, narrow key that requires being pressed with the right pinkie. This would not be a good change since most peoples' pinkies are their weakest finger. Some ergonomic keyboards have a slightly curved spacebar or a separated spacebar for each thumb.

*'''Arrow Key (Rotate to Adjust Direction)'''
This is essentially a {{w|Jog dial|jog dial}}, or similar {{w|Rotary encoder|rotary encoder}}. These are sometimes used with keyboards: as controls for volume, video editing, or drawing.
Many computer keyboards have four {{w|arrow keys}}: up, left, right, and down. However, the XKeyboarCD just has one that can be rotated. This has the added bonus of allowing the arrow keys to point more than four different directions. In a keyboard, it would be awkward to operate as going from horizontally left to horizontally right, for example, would require the user to rotate the key first and then press it, which wastes precious time when playing a video game like [http://explainxkcd.com/1608 the hoverboard comic], where you have to rapidly press arrow keys to move around. It would not let one press multiple arrow keys at once. Trackpoint devices provide similar joystick-like direction function, but are easier to control with a finger.

*'''15 Puzzle-Style Numberpad'''
A {{w|15 puzzle}} is a square containing fifteen smaller squares and one blank spot, which allows the squares to be moved around. The squares are shuffled and then reassembled as a game or pastime, and are usually labelled 1-15 (as is the case here) or, when assembled properly, create a picture. A {{w|Numeric keypad|numberpad}} in this style would be frustrating to use for typing numbers, as they could shift (or be shifted) around, but could provide a fun feature to use as a game. Alternatively the keys could be rearranged as with the Rubik`s keys. How this would be used to generate numeric input is unclear, but the presence of 16 positions suggests {{w|hexadecimal}} input is possible. Keyboard keypads do have around 17 keys, but only 0-9 usually have numbers whereas the XKCD keypad has numbers 1-15 in the middle of the numberpad probably also surrounded by the more conventional arithmetic operators, enter, and decimal point.

*'''Ergonomic Design'''
The cylindrical portion of the keyboard is advertised as being an ergonomic design. Most ergonomic keyboards are both curved into a convex shape and split in the middle, with the blocks of keys on either side rotated around the vertical axis. This is done to follow natural arm and finger movements more closely, that is, avoid forcing the user to rotate their arms and hands to match the flat and rectangular key arrangement of a non-ergonomic keyboard. Some ergonomic keyboards come in unconventional form factors, such as vertical keyboards, to allow the user's hands to rest in more neutral positions or to change positions throughout the day, but the cylinder shape presented here is a ''concave'' shape which requires the user to lift and twist his arms to reach certain keys (or roll the cylinder from side to side), which would be an even more strenuous motion than typing on a standard keyboard. The slogan of the keyboard - "for power users and their powerful fingers" fits this difficulty, but makes no sense as a feature.

*'''Title Text'''
The title text references sound changes in languages. Every language (and indeed, every dialect) routinely undergoes changes in its sounds and phonemes, in a mostly regular and systematic, but not totally predictable way (otherways the dialects would sound the same and also the century, when a shift occurs, and the rate of change are not predictable). While not only vowels are affected, in languages with many vowels such as English, they're particularly likely to shift around and/or merge. While having dynamic keycaps that change can actually come in handy, the feature of only having vowels change in response to sound shifts is a bit less so. One normally enters the spelling and not the pronunciation of words (except with some Asian input systems). The spelling and pronunciation do not change at the same time.

First, while changes in how we pronounce words are always ongoing, the way we write words down tends to stay relatively static, and thahs wiy wuhd faynd thaet werds biykahm ihncaampriyhehnsihbuhl duw tuw now laanger biyihng spehlld aes they wer bihfaor. Second, English only uses five glyphs (aeiou) and a variety of methods to represent four times as many vowel sounds, so the software would need to have a way to handling that (in some dialects "bird" and "turn" for example, have the same vowel but are represented by "ir" and "ur", as it also ''can'' be by the "er" in the bird called the "{{w|tern}}" - or not). Third, vowel shifts are not ubiquitous: the {{w|Caught-cot merger}}, for example, is a phenomenon happening across some parts (but not all) of the US and UK. Therefore, while some people would say "caught" and "cot have the same vowel it should be spelled the same by the keyboard, but others would say they're two different vowels and should not be spelled identically. Fourth, sound shifts tend to occur over a relatively long period of time (in terms of human lifetimes), so a user would probably find the keycaps only change once or twice. All in all, this is not a very useful feature.

An alternative explanation is that the keys actually map to the {{w|International Phonetic Alphabet}} and converts what you type into English words (and the vowel changes). The IPA is an alphabet used in linguistics and language teaching, designed to represent every phoneme present in languages of the world unambiguously, with optional modifiers to indicate more subtle nuances in pronunciation, intonation and speech pathology. This alphabet consists of 107 letters and 56 modifiers (with some letters shared with the Latin and Greek alphabets), which would explain the large number of keys. In that case, the feature remains questionable since it only handles vowel shifts and not consonants, and anybody who'd use an IPA-keyboard would probably need to type out the phonology of other languages and appreciate not having to find a key has moved because English has undergone a vowel shift.

*'''Trivia'''
This is the second time that the "xkcd" has been used around a middle word, which uses some of the xkcd letters to form this word. The first was [[1506: xkcloud]] - XKC lou D, to spell ClouD with the C and D from XKCD, in that comic the letters were all lowercase. In this comic the Keyboard, has an X before the word and a C before the D with the xkcd letters capitalized.

:[The keyboard has many more keys than a usual Keyboard. Usual keyboards for stationary computers typically have a few of the rows with 21 keys, and then some with fewer. This Keyboard has 28 keys on the top row. The other rows have special keys that make it difficult to compare, but there is basically also room for 28 in the bottom row, except one spot where there is one key in a space for 2x2 keys. Begining from the bottom and coutning keys there are 27. Skipping those that take up space in two or more rows, when going to the next row from the bottom there are 23, then 24, then 18, then 27 and finally 28 keys in the top row, for a total of 147 keys (vs 105 on a regular keyboard). Then there are 54 extra keys above the keyboard to the left (27 shown) and 156 in 6 rows of 26 to the right for a total of 357 keys 330 shown. All six rows have keys all the way over with no empty space in between, as there are on regular keyboards. Also there are no space between the top row (with F1 button etc) and those below. At each side of the keyboard the keys do no align at the edges, which is normally the case. The keyboard has several special features, most of which are labeled. The only special features that is not labeled is a small square with 2x2 keys that are elevated a bit above all other keys. It is in the region above the normal position of the four arrows. All eight other special features have an arrow pointing to them from their labels. Here below is a description of the labeled items as well as a transcript of their labels. They are listed in the order of their labels first above and then below the keyboard going from left to right.]

The numbers do not come in order from 1 to 15, but rather in a jumble. Also the empty hole is not a full key spot. Instead it is in the second row of numbers, with a bit more space to the left than to the right of the middle of the three keys.]

1690: Time-Tracking Software

2021-02-18T17:06:13Z

162.158.63.232: /* Explanation */

{{comic
| number = 1690
| date = June 6, 2016
| title = Time-Tracking Software
| image = time_tracking_software.png
| titletext = 'List of helicopter prison escapes' and 'List of sexually active popes' are both entertainingly long, but sadly there's no 'List of helicopter prison escapes involving sexually active popes.'
}}

==Explanation==
In this comic, [[Randall]] uses {{w|time-tracking software}}, which is intended to increase productivity by identifying how you are spending time, that reveals that he is doing frivolous and pointless things that take up large amounts of his time. He makes remixes, edits ''{{w|Star Wars}}'' footage, reads strange (albeit entertaining) Wikipedia articles (see [[214: The Problem with Wikipedia]]), and even spends a large amount of time adjusting this software, all without getting anything useful done. Thus, he is embarrassed at this revelation. This time waste is a common subject on xkcd, as shown for instance in the comic mentioned above.

The visual appearance of {{w|Lightsaber|lightsabers}} in the ''Star Wars'' movies of the {{w|Star_Wars#Original_trilogy|original trilogy}} has been {{w|List_of_changes_in_Star_Wars_re-releases|digitally changed}} twice during the re-releases for the 2004 DVD and 2011 Blu-ray releases. There are several ''Star Wars'' fans that feel the need to alter the movies (mainly to revert the changes made in the re-release), but so far nobody felt the need to replace lightsabers with metal swords.

"{{w|Jack & Diane}}" is a rock song written in 1982 by {{w|John Mellencamp}}. "[https://youtu.be/h04CH9YZcpI?t=56 Suckin' on a chili dog outside the tastee freeze]" is the first line of the second verse of the song (see the [http://www.metrolyrics.com/jack-and-diane-lyrics-john-mellencamp.html lyrics here]). [http://lyricsmusic.name/john-mellencamp-lyrics/words-music-john-mellencamps-greatest-hits/jack-and-diane.html A remix] made using just this line would probably sound a bit repetitive (listen for instance to [http://svantana.bandcamp.com/track/you-were-workin-as-a-waitress-in-a-cocktail-bar this re-mix] of [https://www.youtube.com/watch?v=uPudE8nDog0 "Don't You Want Me"], that almost only uses the first line of the song).

Two Wikipedia lists are mentioned in the comic and title text; {{w|List of helicopter prison escapes}} and {{w|List of sexually active popes}}. Given that the Pope is supposed to be {{w|Clerical celibacy|celibate}} (at least after 1139), the mere fact that more than ten popes have been involved in sexual activity, even after 1139, is both amusing and intriguing. There are more than forty entries in the helicopter escape list for real-life attempts (plus 16 in fiction); not all of them succeeded, but several did!

This xkcd comic was published on June 6th. On that day, the Wikipedia article "List of helicopter prison escapes involving sexually active popes" was created and subsequently deleted.

On June 7th, the [https://www.facebook.com/wikipedia/ Wikipedia Facebook page] [https://www.facebook.com/wikipedia/posts/10154133410693346 posted a link] to the ''List of helicopter prison escapes'' article. A user [https://www.facebook.com/wikipedia/posts/10154133410693346?comment_id=10154135208533346&comment_tracking=%7B%22tn%22%3A%22R9%22%7D commented] asking if the article was posted on Facebook due to the xkcd comic, and Wikipedia [https://www.facebook.com/wikipedia/posts/10154133410693346?comment_id=10154135208533346&reply_comment_id=10154135327863346&comment_tracking=%7B%22tn%22%3A%22R9%22%7D replied] by pasting an image of the xkcd comic, which seems to indicate that the Wikipedia representative running the Facebook page was aware of this xkcd comic and posted the list in reference to the comic.

In the title text, Randall mentions his disappointment with the lack of a Wikipedia list stemming from the intersection of the two; that is, a helicopter prison escape involving a sexually active pope. With the last (known) sexually active pope being Pope Leo XII in the 1820s, and helicopter predecessors only taking flight in 1907, and mass production of helicopters not occurring until the 1950s, such an event has probably never happened.{{Citation needed}}

The Wikipedia list of sexually active popes has been mentioned before in the [[what if?]] ''{{what if|109|Into the Blue}}'' on infinitely powerful lasers, and after noting that such a thing cannot exist, the list is offered as a replacement for entertainment.

The comic [[1692: Man Page]] was released later that week and also mentioned the pope.

2417: 1/1,000th Scale World

2021-02-02T01:10:34Z

162.158.63.232:

{{comic
| number = 2417
| date = January 27, 2021
| title = 1/1,000th Scale World
| image = 1_1000th_scale_world.png

}}

==Explanation==
{{incomplete|Created by a STATUE OF LIBERTY MINIFIG. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This comic is the third comic in the [[:Category:Scale World|Scale World]] series, this time with a smaller scale-factor and thus a larger world than the earlier ones. As in the previous comics, [[Randall]] has a seemingly complete copy of Earth, this time at a 1:1000 scale, with various features and warnings labeled. Again, real-world features and phenomena are replicated at scale. As before, the model is very extensive, with in this case several underground neutrino detectors/observatories being replicated.

Several of the warnings point out humorous consequences of the scale, such as non-scaled goldfish eating scaled-down blue whales. Other than the usual homo sapiens, introduction of non-scaled animals into the scaled world (with consistently humorous consequences) is an addition to the earlier comics of the series.

===Table===
{| class="wikitable"
!Rule
!Reason
!Notes
|-
| Keep hot objects off the ice sheet over the south pole neutrino observatory
| Hot objects may emit Cherenkov radiation, which would result in the observatory detecting false positives of neutrino observations. They may also melt the ice that shields the detectors from other particles that would trigger false positives.
| The fact that people are not supposed to create false positives implies that the neutrino detector is functional.
|-
| Be patient: Niagara falls will take a few minutes to fill your water glass
| The flow rate is scaled down with the size. According to the [[what if]] ''{{what if|147|Niagara Straw}}, the Niagara Falls flow is regulated to 100,000 cubic feet per second on the tourist season and to 50,000 cubic feet per second offseason and at night. Once scaled to 1/1000, that flow would be 2.83 or 1.41ml per second. If a standard glass of water is 250ml, it would take about 90–180 seconds for the waterfall to fill it.

However, a 1/1000th replica of scale Niagra falls would be over a meter wide, so without some kind of system to divert the whole flow into one spot, it would not be possible to fill a glass this quickly. Also, the height of the scaled-down Niagra falls would be 5cm, with another 5cm between the water level and the riverbed, so it might be difficult to fill a glass depending on its height.
| This item is likely to be a reference to the famous Arthur C. Clarke quote: "Getting information from the internet is like getting a glass of water from the Niagara Falls."
|-
| Watch for small planes
| Taking the popular Cessna 172 as an example, 1/1000th scale small planes would be about 8mm in length, and cruise at speeds of about 6cm/s, much slower than comparable flying insects. A Cessna of that size traveling at that speed would probably cause much more damage to itself than a person if it crashed into one, so the warning is probably there to protect the models rather than the guests. The planes are flying along 1-foot {{w|Flight level|flight levels}} according to the direction they are flying in, following the {{w|Flight level#Semicircular/hemispheric rule|semicircular rule}} of aviation.
|
|-
| Warning! Choking hazard! Keep small children away from ascending/descending airliners
| Airplanes are apparently small enough for children to fit into their mouths but large enough to potentially make them choke.
| In the US, small parts are defined by [https://www.cpsc.gov/Business--Manufacturing/Business-Education/Business-Guidance/Small-Parts-for-Toys-and-Childrens-Products 16 C.F.R. Part 1501.2] as fitting in a cylindrical test fixture of 1.25 inches diameter that approximates the size of the fully expanded throat of a child under three years old. Once scaled, any object smaller than 31.75 meters would fit in that cylinder. A lot of medium-sized and small airplanes would qualify. Furthermore, since pieces that break off during testing that simulates use or abuse by children could also pose a choking hazard, even large airliners are also a choking hazard because stripped wings and parts of the fuselage would fit in the required size.
|-
| Do not remove safety caps
| This is a reference to the warning, "Be careful not to step on cities with especially pointy towers, like Toronto, Seattle, and Dubai" from [[2411: 1/10,000th Scale World]]. It's possible that many visitors to that scaled world did not heed the warnings and complained to the scaled world's creators, causing them to cover pointy towers with safety caps for this scaled world. However, now there are [[Black Hat|people who apparently want to cause harm to others]], or at least don't care about not causing harm to others, by removing these safety caps.
The tip of the Burj Khalifa of Dubai - the tallest building in the scale world - appears to be about a meter and a half wide, or 1.5mm at 1/1000th scale. The other buildings pictured are the CN Tower of Toronto and the Eiffel Tower of Paris. (The Seattle Space Needle, referenced above, does not appear.)
|
|-
| No open flames in Zeppelin area
| The iconic Zeppelins, as with many other early airships, were filled with hydrogen to use its very low density to give them the buoyancy required to fly. However, it is also very flammable and prone to explosions, with other materials used in their construction also being notably liable to becoming a fire-danger. The most famous of these disasters was when the {{w|Hindenburg disaster|Hindenburg}} caught fire in 1937.
In more modern times, almost all airships, blimps and balloons use helium (and/or hot-air, sometimes in combination). This includes the six operational 'Zeppelin NT' craft, a modern semi-rigid design produced by the spiritual and economic successor to the original Zeppelin company.
| Helium is a noble gas and therefore not flammable, with modern gondola and gasbag/envelope materials also being far less flammable in their own right. If Randall's scale model has airships of any sort, this may reflect an anachronistic mismatch against the clearly modern era neutrino detectors and other features. But any non-scale flames could be several magnitudes larger than 'normal' scaled-down hazards, so considered more of a ''general'' dannger to the airships; as they also ought to be to many other elements of the scale world.
|-
| Do not bother the meteor crater ducks
| It is unclear whether the 'meteor crater' represents specifically {{w|Meteor Crater}} in Arizona, or some other unspecified or abstract meteor crater. The former is over a kilometer wide, so at 1/1000 scale it could be a small duck pond of 1.186m diameter, and 17cm deep at its lowest point. This is (barely) enough space for a duck to swim in if filled to the brim with water. Meteor craters often leave behind lakes as they become filled with water, with examples being {{w|Lake Siljan}} in Europe. The ducks appear to be regular-sized as opposed to scaled down, so they were probably added afterwards as an attraction as opposed to them coming with the landscape.
| Even though a lot of craters are filled with lakes, Meteor Crater is not filled with water, or ducks, in real life. {{Citation needed}}
|-
| Trip hazard: The Gateway Arch
| The {{w|Gateway Arch}} is a monument in Saint Louis, Missouri. Being a 192 m high arch, once scaled it would be 19.2 cm high, ideal for tripping.
|
|-
| Drone altitude limit
| The FAA drone altitude limit is 400ft above the ground, which would be about 12cm in 1/1000th scale. This appears to be the number Randall is using, as the limit in the comic is about the same height as the pyramids, which are also around 400ft tall in the real world.
|
|-
| Do not mix up the USS Enterprises
|
The ship is presumably a model of the USS Enterprise (CVN-65), the longest naval vessel ever built, which would be 34cm long in 1/1000th scale.
The spaceship is the USS Enterprise (NCC-1701) from the Star Trek franchise.
It's unclear whether mixing up the models is prohibited because it would damage them, or simply because that's not where they are supposed to be.
The Starship Enterprise might be corroded by seawater, or unable to handle external pressure (spacecraft are designed for the exact opposite pressures in a vacuum). If lifted into the air, the Aircraft Carrier Enterprise would probably fall back down because it can't fly {{Citation needed}} (and be damaged or even destroyed upon hitting the ground or water surface), but then again, it's unclear how the model Enterprise is able to fly or hover.
The Enterprise from the JJ Abrams films has been seen to hide underwater and take off again without significant problems, and the Original Series version has been seen to fly (high) in the Earth's atmosphere on several occasions. However, it is unclear whether other versions of the Enterprise also possess this standard operational ability, nor which version is represented in the comic.

|-
| No connecting the Dead Sea to the ocean
| The surface of the Dead Sea is 430.5 metres (1,412 ft) below sea level, so connecting it to the ocean would cause catastrophic flooding of the area. If there are models of Israeli and Jordanian cities next to the Dead Sea, they could get damaged by the water. Also, the model world would be less accurate because the Dead Sea is not connected to the ocean in real life.
| This has actually been proposed: {{w|Mediterranean–Dead Sea Canal|Dead Sea Canal}}
|-
| Do not let ants into the Sudbury Neutrino Observatory
| The Sudbury Neutrino Observatory was a neutrino observatory located at the 2100-meter depth level of the Creighton Mine in Ontario, Canada. It has since been upgraded into the SNOLAB facility. At 1/1000th scale, its meters-scale tunnels would be millimeters across, and its 3,000-meter maximum depth would reach three meters underground. This would make it ideal for habitation by ants, but as the mine is in rock, and not soil, extracting the ants after they get in would be much more difficult than most pest control operations. Also, some types of ants would eat the insulation around the wires, causing electrical short-circuits and other problems, which would be bad because the model's neutrino detectors are apparently functional. (See the row about the south pole neutrino observatory.)

| The {{w|Golden Gate Bridge}} is a suspension bridge in San Francisco, 2.7 km long and 27 m wide. Scaled-down, it would be 2.7 m long and 2.7 cm wide, and it would be tempting to use it as a tightrope.
| In 1987, approximately 300,000 people [https://www.sfgate.com/local-donotuse/article/Golden-Gate-bridge-walk-1987-anniversary-disaster-13896571.php walked across the Golden Gate Bridge], which could be the largest weight it has supported: 80kg * 300,000 = 2.4*10^7kg. A visitor to the scaled world would expect to weigh a much as (1000^3) = 1 billion native scaled humans, above the [https://www.vibrationdata.com/golden.htm total mass of the bridge].

| Do not remove Statue of Liberty LEGO minifig
| Whoever has made this model has decided to use a small LEGO minifigure rather than a more accurately sculpted replica of the Statue of Liberty. The person would likely not want it to be removed because it would then have to be replaced.
| LEGO has released a [https://www.lego.com/en-us/product/magnet-statue-of-liberty-2016-853600 Statue of Liberty minifigure] which is 5.3cm tall. The real Statue of Liberty, from head to toe, is 46 meters tall. At 1/1000 scale this would be a 4.6cm figurine, so the LEGO minifigure would indeed be an appropriate representation at that scale.
|-
| Please stop releasing goldfish in the ocean. They keep eating the blue whales.
| Blue whales are the largest animal species in the world. They usually grow to about 20m long in real life, meaning that at 1/1000th scale they would be only 2cm long, meaning that they could be consumed by a goldfish. Goldfish are omnivores, so they would eat tiny blue whales. But they are also freshwater fish, so would they survive long enough in seawater to put the whales at risk? This could perhaps be considered carping. And perhaps Randall's customers have access to [https://mashable.com/2017/09/20/saltwater-bearing-goldfish-australia/ Australian goldfish].

This might also be a reference to the video game ''Tasty Blue,'' in which a goldfish eats animals of increasing size and eventually becomes large enough to eat blue whales.
|
|-
| We're worried that a regular whale will get into a 30-foot-deep ocean trench section and filter-feed on all the tiny whales.
| The ~10 deepest ocean trenches are in the vicinity of 30,000 ft, so they would be 30 ft deep in the model. A blue whale is about 15 ft tall, and there are several smaller species of whale, so a full-sized whale would fit into the scaled-down trench.
Blue whales usually eat {{w|krill}}; the tiny whales would be about the same size, though nowhere near the same density, so any feeding whale would soon go hungry. However, a 15-foot (ca. 5 meter) diameter whale in a 30-foot (ca. 9 m) trench (ignoring displacement, for the moment) would most likely be too stressed to eat.
| Following on to the full-size goldfish:scaled-down blue whale comparison, the title text compares a full-sized whale to the depth of the scaled-down ocean.

162.158.63.232: Added a more accurate haiku

A prime number must also be a natural number greater that one. {{unsigned|‎204.8.8.13}}

I removed the paragraph about the haiku being off, as it is not "top prime's divisors," but "top prime's divisors' " (notice the second apostrophe). So the question is actually what the (prime) factors of the product of all prime divisors plus one are. [[User:KillaBilla|KillaBilla]] ([[User talk:KillaBilla|talk]]) 21:57, 12 June 2014 (UTC)

: I've put it back, since the paragraph is correct - the proof is incorrect. That second apostrophe just means it is the product belonging to the top prime's divisors. The product of the top prime's divisors is just the top prime. --[[Special:Contributions/141.101.98.234|141.101.98.234]] 14:40, 5 April 2015 (UTC)

}}

==Explanation==
{{incomplete|Created by a BAT. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}
This comic is another comic in a [[:Category:COVID-19|series of comics]] related to the {{w|2019–20 coronavirus outbreak|2020 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}}, which causes {{w|COVID-19}}.

Cueball partially echoes a statement made by anti-vaccine activists about "Big Pharma" (the powerful and profit-driven companies who develop pharmaceutical drugs such as vaccines). Anti-vaccine protesters falsely believe that vaccines contain harmful toxins (such as HIV proteins, aluminum salts, formaldehyde, mercury, and nanoparticles) that cause ill effects on the human body, and that the corporations that make them are not to be trusted because they are exploiting a captive public for profit while disregarding public health. The joke is that Cueball is revealed to be not talking about Big Pharma but, instead, bats.

According to the WHO, COVID-19 has an ecological origin in bat populations. Hence, Cueball sees the virus as something developed by bats, and the ambiguity by which he expresses his desire to not be infected adds to the joke.

The comic could simply be seen to serve as a compelling argument against the anti-vaccine movement, which is often criticized for spreading misinformation and increasing rates of disease, especially since the start of the COVID-19 pandemic. This comic comes shortly after the news of the development of several COVID-19 vaccines with high rates of success; there are concerns that herd immunity may be delayed if people refuse to take the vaccine.

The title text refers to getting immunity the old fashioned way, i.e. catching the disease and waiting for your immune system to build up a response. This is usually considered healthful when immunity to minor diseases is common, and can avoid the sudden forced evolution of new diseases among extensively hypercareful communities, but developing natural immunity is certainly incredibly dangerous during a pandemic of a serious illness. One joke here is that many anti-vaxxers claim that it is more natural to not take a vaccine. Because many people conflate "natural" with "healthful", the assumption underlying the claim "it is more natural to not take a vaccine" is that it is therefore more healthful. In fact, many natural things are not healthful.{{Citation needed}}

2235: Group Chat Rules

2019-12-11T20:08:43Z

162.158.63.232: /* Explanation */

{{comic
| number = 2235
| date = November 29, 2019
| title = Group Chat Rules
| image = group_chat_rules.png
| titletext = There's no group chat member more enigmatic than the cool person who you all assume has the chat on mute, but who then instantly chimes in with no delay the moment something relevant to them is mentioned.
}}

==Explanation==
{{incomplete|Created by a GROUP CHAT Do NOT delete this tag too soon.}}
In this comic Randall is outlining the rules of a group chat, such as {{w|Internet Relay Chat}} (IRC), {{w|Slack (software)|Slack}}, {{w|Discord (software)|Discord}}, {{w|WeChat}}, {{w|Discourse (software)|Discourse}}, and the like.

1. '''Once you've sent a typing notification, you have to say ''something,'' c'mon.'''

Typing notification, often called a "typing awareness indicator," is a feature of some instant messaging systems, showing a message such as "Typing..." with the typer's name to the other participants, causing them in many cases to wait to receive the message before typing something of their own. When the typer stops without sending anything, this can seem anticlimactic and potentially disruptive if it recurs. Randall's rule is that you must say something once you've started typing, to avoid the awkwardness of awaiting a person's reply. See also [[1886: Typing Notifications]].

2. '''Show you care by trimming the tracking junk off links you paste.'''

Some URL links may have tracking information attached to the end of them, to show the origin of the URL and other information. {{w|UTM parameters}} are an example of URL parameters (the part of a URL starting with a question mark) which are used to track utilization of the URL from one user to another. Many news and marketing-related websites include such tracking codes with any visit to one of their web pages in an attempt to see the source of the URL for subsequent visits. Many people consider this a violation of privacy as well as a source of clutter, and make an effort to remove the parameters from URLs when they are not necessary for obtaining the requested content. For example, [https://www.dyson.com/sticks/dyson-v8-absolute-nickel-iron.html?ranMID=36310&ranEAID=lw9MynSeamY&ranSiteID=lw9MynSeamY-w42lWd1QYp3RrUefCg_osA&siteID=lw9MynSeamY-w42lWd1QYp3RrUefCg_osA&utm_source=Slickdeals+LLC&utm_medium=affiliate&utm_campaign=us_en__na__na__na__purchase&utm_term=&utm_content=rakuten_1&dclid=CjkKEQiAt_PuBRC2vOSG5pnYqN0BEiQATx34W-U3rsbKLg-BO9ep4IJKz6JxmZrHTqS7JKmZqSrWmKLw_wcB&ranMID=36310&ranEAID=lw9MynSeamY&ranSiteID=lw9MynSeamY-z5miuzSsmyWevVXB._R14g&siteID=lw9MynSeamY-z5miuzSsmyWevVXB._R14g&utm_source=Slickdeals+LLC&utm_medium=affiliate&utm_campaign=us_en__na__na__na__purchase&utm_term=&utm_content=rakuten_1 this url] has a lot of tracking information to show that it was originally accessed from Slickdeals, which can be removed to produce [https://www.dyson.com/sticks/dyson-v8-absolute-nickel-iron.html a much shorter URL] for the same web page. Randall asks the users of group chat to politely remove the tracking code, though other parameters may be involved in an important non-tracking way (such as the lat, lon and zoom level giving the focus of a Google Map link) and it isn't always obvious which parts are which - or both tied together!

3. '''Do not talk about ''Fight Club'' (1999).'''

This is a reference to the 1999 film ''{{w|Fight Club}}'', where the main character forms an eponymous "Fight Club," an underground club for men to fight recreationally. In [http://www.diggingforfire.net/FightClub/ the rules for Fight Club] the first and second "rules" are "You do not talk about FIGHT CLUB.", which Randall parodies in this comic, by making a rule to not talk about the film ''Fight Club'' and placing this rule third in the list. See also [[922: Fight Club]] and [[109: Spoiler Alert]].

4. '''There are two types of chats: those with a relevant group name, and those where the name is random nonsense that changes regularly. Only the second kind are good.'''

Some group chats frequently change the name of their title or the names of their channels, for example to reference upcoming events or inside jokes, or to reflect the topic of the current conversation. Often, these names do not get changed back until someone decides to change it to a new inside joke/etc. Randall claims that those are the only good kind, compared to those that never change group names, perhaps implying a singular focus is less interesting than a dynamic chat that often changes names.

5. '''When mentioning it elsewhere, always just refer to it as "the group chat" to create an aura of exclusive mystery.'''

Many people have to deal with several kinds of group chat in the same organization, so referring to "the group chat" within such an organization may be confusingly ambiguous. Also, calling a chat "the group chat" can serve to exclude those who don't already know about it.

6. '''Robert's Rules of Order are optional but encouraged.'''

''{{w|Robert's Rules of Order}}'' are one of the authoritative codifications of {{w|parliamentary procedure}} used to formalize decision-making in organizations required to document their activities such as governments and sometimes civic organizations and corporations. While people required to use ''Robert's Rules'' might use group chat to plan their {{w|Agenda (meeting)|agenda}} — even going so far as to prepare a {{w|pro forma}} script for a meeting in accordance with parliamentary procedure which represents their positions and deliberations in advance — and to compose, revise, and approve their {{w|minutes}}, it is unlikely that group chat participants would follow ''Robert's Rules'' prior to their formal meeting.

7. '''Periodically part of the group will split off to form a new chat with everyone minus one person. This is how group chats reproduce; don't draw attention to it.'''

Some people who use group chat too frequently or for unimportant messages or both will cause their colleagues to attempt to achieve greater productivity by excluding them from an alternate chat, from which notifications, for example, are less annoying and more useful. Alternatively, a person could be excluded from a chat to hide things from them, such as to plan a surprise for them, or because that one person has been disruptive or annoying to the point that everyone else wants to continue the conversation without their continued input. It appears that the chat is a [https://en.wikipedia.org/wiki/Swarming_(honey_bee) honey bee hive reproducing by swarming]. When purposely excluding someone by creating a new group, you would probably not want them to know you have done so as they might otherwise attempt to re-join in the new chat; that's likely the real reason one should not talk about or draw attention to the fact that it happened.

8. '''Since there's no algorithmic feed, the responsibility for injecting lots of garbage no one asked for falls on you.'''

Tools such as {{w|IFTTT}} and {{w|IRC bot}}s (or "bots" in this context) are used to provide group chat channels with information automatically taken from external sources of various sorts, such as emails to a support address or commits to source code control systems. Randall suggests that when such algorithmically-provided information is not available, it is incumbent upon chat participants to provide sufficiently verbose replacements. The "algorithmic feed" may also refer to the newsfeed type of systems that Facebook or other social networking sites use, to order posts for a user to view.

9. '''The enumeration, in these rules, of certain rights, shall not be construed to deny or disparage others retained by the people.'''

This is a reference to the {{w|Ninth Amendment to the United States Constitution}}, which reserves the various [[Wikipedia:natural rights|natural rights]] not specifically mentioned in the Constitution. Per Wikipedia, this right was included because "future generations might argue that, because a certain right was not listed in the Bill of Rights, it did not exist." The Ninth Amendment was also referenced in [[1998: GDPR]].

10. '''Sorry about all the notifications.'''

Here, Randall apologizes for all the notifications for the messages sent in group chat. Group chat features often result in more notifications than designers of notification systems anticipated or intended. If each of these ten rules were sent as a separate message in group chat, they might likely end with such an apology.

The title text expresses appreciation for group chat participants who remain silent except for promptly replying on topics pertinent to them.

2227: Transit of Mercury

| titletext = For some reason the water in my pool is green and there's a weird film on the surface #nofilter
}}

==Explanation==
{{incomplete|Created by MY TELESCOPE'S IMAGING SENSOR. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

This comic is in reference to [https://www.theverge.com/2019/11/11/20958727/mercury-transit-sun-planet-nasa-astronomy the transit of the planet Mercury across the Sun] on November 11, 2019 (the date of the publication of this comic), which appeared from Earth as a small black dot moving against the background of the Sun. [[Randall]] has made comics about solar transits before, albeit about the transit of the International Space Station, in [[1828: ISS Solar Transit]] and [[1830: ISS Solar Transit 2]]. Viewing a solar transit requires a {{w|Astronomical filter|special lens filter}} to prevent the intense light from the Sun from burning out a telescope's imaging sensor.

The {{w|hashtag}} #nofilter is typically used on photo sharing sites, especially Instagram, to humblebrag about having encountered situations so photogenic that no further image enhancement ("{{w|Photographic filter|filter}}") is required to prepare them for general advertisement. In this comic, the hashtag is instead used to cap off an image about the predicament of the poster, where the lack of a proper astronomic filter has led to damage of personal property. The image shown on the comic is quite bright and {{w|Clipping (photography)|blown out}}, and though the poster did manage to get a picture of Mercury, the sun's bright light permanently damaged their telescope.

The title text refers to a still different meaning of the word "filter"; it imagines a swimming pool growing {{w|Algae|green scum}} in the absence of a {{w|Swimming_pool_sanitation#Private_pool_filtration|water filter}}, as opposed to a photographic or astronomic filter.

Although not directly referred to in this comic, a third common [https://www.urbandictionary.com/define.php?term=No%20Filter variation of "No filter"] is possibly alluded to here and can refer to someone who makes, or posts, tactlessly candid comments. While often this means comments that reflect the individual's actual views which are potentially offensive or socially unacceptable, it could also refer to someone who posts every mundane detail of their lives, such as what is growing in their swimming pool (as is shown in the title text). Multiple layers of meaning makes this pretty clever word play.

Megan is talking to Cueball about alternate histories, which are when someone tries to imagine what might have happened had a historic event gone differently. Examples would be; What if the Americans had lost the American Revolution? What if Napoleon had won Waterloo? and the one featured in this comic, What if the Allies had lost World War 2.

Notably in the Hearts of Iron IV mods series beginning with "Kaiserreich", this is exactly what happens with World War One, with each mod going a level deeper.

2148: Cubesat Launch

2019-05-11T12:34:22Z

162.158.63.232: Minor fixes

{{comic
| number = 2148
| date = May 10, 2019
| title = CubeSat Launch
| image = cubesat_launch.png
| titletext = Luckily, the damages were partly offset by the prize money we got from accidentally winning the nearby water skiing championship tournament.
}}

==Explanation==
{{incomplete|Created by a launch accident investigator. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

A {{w|CubeSat}} (aka U-class spacecraft) is a miniature artificial-satellite with cubic dimensions of 10 cm × 10 cm × 11.35 cm (~ 4 in × 4 in × 4.5 in), and masses of about 1.33 kg (2.9 lbs) per unit. CubeSats are put into orbit from the International Space Station or launched as secondary payloads. As of January 2019, at least 900 CubeSats have successively achieved orbit, and at least 80 have been destroyed in launch failures. They typically function as Earth observation satellites, amateur radio emitters as well as testing prototype small-satellite technology.

The comic begins with [[Megan]] telling [[Cueball]] that being officially part of a CubeSat launch is very expensive, but she has an idea for a much cheaper alternative: use a fishing line on a drone to attach to a rocket just before launch, with the CubeSat attached to the other end of the fishing line so it gets pulled into space.

In reality, this plan would fail for multiple reasons.

# Security would presumably prevent the drone from reaching the rocket.
# Even if Megan were to pilot the drone past security undetected, the launch would have been scrubbed as soon as any observer noticed the drone near the rocket and tell Mission Control, who would order a countdown halt and stop the rocket launch, which prevents Megan from launching her CubeSat in the first place - after which Security would locate the drone's user and take her into custody.
# The unshielded CubeSat would likely be destroyed by aerodynamic forces.
# The drone would not be able to attach itself to the rocket in a way that would remain secure.
# The fishing line would not hold - either the rocket exhaust would sever it, or the force from the CubeSat, gravity, and the acceleration of the rocket would become more than its tensile strength could withstand.
# Precise weight is an important number during launch. The extra weight of the drone, the fishing line, the air drag from the drone, and the CubeSat all would combine to put more downward force on the rocket. This unexpected extra weight would not have been calculated and could turn the rocket off-course, along with making it spend more propellant in countering the forces exerted this way. This may result in the rocket not achieving the planned orbit, and may have to orbit at a lower altitude.

Upon realizing her plan, Cueball immediately responds with "uh-oh", indicating his concern, but Megan assures him that it will be fine, before piloting the drone towards the rocket. She successfully connects the drone to the rocket, and the rocket lifts off.

Whatever her plan was, it goes wrong almost immediately. The unexpected force on the rocket from the side causes it to tilt and go off course (implied that it's not due to the comparatively small force of the CubeSat, but because Cueball is standing on the fishing line). Perhaps if the rocket's control software employed {{w|adaptive control}} techniques, it could have maintained control in the presence of this unexpected force. Megan and Cueball get tangled in the fishing line and are carried away. While the fate of the rocket is not shown, it is likely that its unplanned altitude change would activate the automatic termination sequence or result in manual activation of the destruction protocol.

Megan and Cueball miraculously survive and are brought to an investigative board to explain their actions. Megan attempts to defend herself using flawed logic: something was bound to go wrong sooner or later, so it's not her fault that she was the cause. This logic does not account for the fact that this particular rocket's chance to crash was greatly increased by the drone attempting to connect to it. She isn't totally to blame for the accident anyways, since the launch should have been scrubbed as soon as the drone came anywhere near the rocket, and the failure of Mission Control to do so is negligence on their part, and hence they are more responsible for the failure of the mission than Megan and Cueball as they did not follow proper protocol and allowed the launch to occur under unsafe conditions.

The title text describes that the supposedly huge damages they caused were partly covered by the earnings from a water skiing championship, which Cueball and Megan presumably won by being dragged across the water by the rocket. This might be a tangential reference to an incident in the Tintin adventure ''The Black Island'', where the Thompson Twins blunder into and win an aerobatics competition when they compel a mechanic with no flying experience into taking off in pursuit of that volume's antagonists.

Additionally, this is not the first comic to discuss CubeSats; they were also mentioned in [[1866: Russell's Teapot]] and in [[1992: SafetySat]].

Megan's last sentence in the comic is similar to the topic and title text from [[2146: Waiting for the But]] published only four days earlier. This is probably a coincidence though since sentences in that form a not uncommon for excuses. In this scenario the second part could be along the lines of "...but if one can't afford a spot on a cubesat launch, one needs to take risks."

== Dvorak ==

''Title text: I like to think that somewhere out there, there's someone whose personal quest is lobbying TV providers to add an option to switch their on-screen keyboards to Dvorak.''

Using the Dvorak layout when you have to scroll through letters is particularly bad. Since Dvorak is optimized to alternate strokes between hands (by putting all vowels on one side), you would have to spend even more time navigating between letters. [[Special:Contributions/162.158.106.102|162.158.106.102]] 16:03, 15 April 2019 (UTC)

:I suspect that's at least part of the joke in the title text, as Randall is likely aware of that fact. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 16:22, 15 April 2019 (UTC)
I of course had to wonder what TV show they were headed for so I started OUR_PL in Google and got "Our Planet Netflix" so now I know . . .I think. [[Special:Contributions/162.158.214.82|162.158.214.82]] 16:25, 15 April 2019 (UTC)
My Netflix interface takes entries from a keyboard. Found out about 2 weeks ago... It is a Samsung TV and I think the feature was not there from the beginning.[[Special:Contributions/172.68.50.52|172.68.50.52]] 16:59, 15 April 2019 (UTC)

Should it be clarified that Ponytail and Cueball are sitting in one chair? The drawing seemed unclear to me at first. --[[User:Youforgotthisthing|Youforgotthisthing]] ([[User talk:Youforgotthisthing|talk]]) 18:03, 15 April 2019 (UTC) One chair? Or a sofa or a loveseat?? [[Special:Contributions/162.158.214.82|162.158.214.82]] 11:18, 16 April 2019 (UTC)

I use Dvorak on all my devices when possible and often find myself wishing for Dvorak on-screen keyboards. Sure, there's more absolute distance between consecutive characters on average, but that's offset by me not having to try to remember how QWERTY is laid out. I don't think that the joke here is "Dvorak on-screen keyboards are pointless", I think it's "Dvorak users are such a small percentage of the population that the odds of anyone bothering to cater to them is slim to none, and anyone lobbying for it is wasting their time". [[User:Undergroundmonorail|Undergroundmonorail]] ([[User talk:Undergroundmonorail|talk]]) 18:23, 15 April 2019 (UTC)

== Smart TV Keyboards ==
Randall probably doesn't know / have or use [https://tehnoblog.org/review-wireless-usb-mini-keyboard-for-pc-raspberry-pi-ubuntu-windows-android-xbox-playstation/ these little keyboards] that can literally save you from trouble and excruciating pain from one-by-one letter "typing": {{unsigned|172.68.154.88}}
:This has to be an ad, right? I'm pretty sure Randall "literally" knows about USB keyboards, regardless of form factor.[[Special:Contributions/108.162.216.172|108.162.216.172]] 22:08, 15 April 2019 (UTC)
::Not necessarily, and since the IP's not blatantly vandalizing pages or spamming links to external sites, and this is the talk page, there's no need to remove it for now. But I've collapsed the URL in case it's an attempt at advertising, as we've seen a lot of (fill in the blank)Review accounts created for that purpose, and some are vandalizing pages. [[User:Herobrine|Herobrine]] ([[User talk:Herobrine|talk]]) 07:16, 16 April 2019 (UTC)
:In my case, my smart TV has a remote control app that allows the phone's keyboard to be used. It also provides a trackpad for issuing a cursor more easily. [[User:Baldrickk|Baldrickk]] ([[User talk:Baldrickk|talk]]) 11:07, 16 April 2019 (UTC)
If just all on-screen keyboards were qwerty... Depending on the app some use qwerty and some use alphabetical grids. I'm always struggling to find the right letters in ther latter... It gets worse if alphabetical ordered letters are arranged in a standard keyboard pattern. [[User:Elektrizikekswerk|Elektrizikekswerk]] ([[User talk:Elektrizikekswerk|talk]]) 11:31, 16 April 2019 (UTC)

This got to be so annoying for me that I actually bought Roku streaming boxes for my TV's so that I can use their phone app to replace the remote and can now type on the phone's touch screen instead of going through the usual up-up-left-left-click nonsense. [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 14:14, 16 April 2019 (UTC)

== Weird lines ==
What are those strange curved lines behind Cueball's head? There are also lines next to his legs that suggest that he's kicking them rapidly. It's unusual to see extraneous stuff like this in an XKCD comic. [[User:SteveBaker|SteveBaker]] ([[User talk:SteveBaker|talk]]) 14:16, 16 April 2019 (UTC)

== Use Wired Keyboard ==
Any "smart tv", even cheap ones have USB ports, not just for displaying Picture albums, but you can use any USB keyboard and type on the screen. Some of the better streaming boxes such as the FireTv Media Player (discontinued), NVIDIA Shield, and pretty much any Cable box have them so you may type on the screen rather than click each letter. Also All game consoles allow keyboards now, not just in game, but back in the home screen for typing passwords as well.

2137: Text Entry

2019-04-15T18:04:01Z

162.158.63.232: /* Explanation */

{{comic
| number = 2137
| date = April 15, 2019
| title = Text Entry
| image = text_entry.png
| titletext = I like to think that somewhere out there, there's someone whose personal quest is lobbying TV providers to add an option to switch their on-screen keyboards to Dvorak.
}}

==Explanation==
{{incomplete|Created by a DVORAK LOBBYIST. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

Randall is remarking on the "weirdest" things about the year 2019, the year that this comic was posted. One of the things is the presidency of Donald Trump, which he has discussed [[Sad comics|multiple times]] in the comics. However, another "weirdest" thing is the continued use of "picking letters" to type. This can be seen when doing searches in a TV guide menu or in menus for streaming options like Netflix or Hulu. Some of these mediums allow for voice searches, but the traditional method is still to select letters via a cursor. Cueball is probably looking up "Our Planet" which was a popular Netflix series when this comic was released.

Randall references the "{{w|Score (game)|high score}}" in an arcade game. When achieving a high score in an arcade game, the user typically is able to enter his name or initials into the machine. These are entered by picking letters one by one, as the comic mentions.

The title text mentions the keyboard system {{w|Dvorak Simplified Keyboard|Dvorak}}, which is a keyboard layout patented by August Dvorak and William Dealey. As the Dvorak layout is optimized for more efficient typing with two hands, and is unfamiliar to most people, it would be pointless and overly confusing for users to use for TV selection menus compared to either the more familiar {{w|Qwerty}} layout or showing letters in alphabetical order.

==Transcript==

:Television: O...U...R...SPACE...P...L...
:Remote: Click Click Click

:[Caption below the panel:]
:The weirdest thing about 2019 is obviously that Donald Trump is president, but I think the second weirdest is that you sometimes ''still'' have to type stuff in by picking letters on a screen one at a time with a cursor like you're entering a high score in a 1980s arcade game.

Talk:2101: Technical Analysis

2019-01-21T18:01:10Z

162.158.63.232:

The Tobin citation comes from James Tobin's Fred Hirsch Memorial Lecture "On the Efficiency of the Financial System" in 1984 [https://economicsociologydotorg.files.wordpress.com/2014/12/tobin-on-the-efficiency-of-the-financial-system.pdf].

The explanation says “allego” and “prologue“ are “musical terms such as may be used in the introduction of a performed piece”. That may be true of “prologue” but “allegro”, according to Wikipedia, is “a tempo marking indicate to play fast, quickly and bright”. [[Special:Contributions/108.162.219.58|108.162.219.58]] 11:40, 21 January 2019 (UTC)

:And, derived from this, a movement of a piece that is performed quickly may be referred to as an allegro. It can also be used to refer to an entire piece, such as this piece by Mozart: [https://www.pianostreet.com/mozart-sheet-music/allegro-k-1-f-major.htm] [[User:Kazzie|Kazzie]] ([[User talk:Kazzie|talk]]) 12:00, 21 January 2019 (UTC)
::But based on the placement of the allego and the way it is written it is most likely a tempo. Tempo goes just above the music and in this case it is the only word on the page that is italicized. [[Special:Contributions/162.158.186.108|162.158.186.108]] 14:09, 21 January 2019 (UTC)

How would this compare with “candlestick patterns” - the bathtub one looks like a funny name for a pattern *meant* to signal that prices could rise https://www.investopedia.com/articles/trading/06/advcandlesticks.asp. [[Special:Contributions/172.68.144.145|172.68.144.145]] 13:55, 21 January 2019 (UTC)

1572: xkcd Survey

2019-01-21T17:16:41Z

162.158.63.232:

{{comic
| number = 1572
| date = September 2, 2015
| title = xkcd Survey
| image = xkcd_survey.png
| titletext = The xkcd Survey: Big Data for a Big Planet
}}
*The original comic links to [http://goo.gl/forms/B5RaBeZ6nw The xkcd survey] at Google; which is closed now.

==Explanation==
As the comic image states, it links to a survey created with [https://www.google.com/forms/about/ Google Forms], containing a series of questions. The questions range from mundane typical survey questions such as “Do you have any food allergies?”, to rather strange, such as “Fill this text box with random letters by randomly mashing keys on your leopard.” (See [[1530: Keyboard Mash]]).

The stated goal of the survey is to “create an interesting and unusual data set for people to play with”. A strange data set is a ripe opportunity for a sampling of readers. It's also supposed to be “a search for weird correlations” – presumably the goal is to be able to say things like “people who have been skydiving are (more/less) likely than average to dislike cilantro”. (See also [[882: Significant]] about finding presumably-spurious correlations between unrelated data.)

This explanation will undoubtedly expand when the data comes in.

{{w|Image_map#Client-side_image_map|HTML image maps}} is a technique for marking up areas of an image on a web page, such that each area can be a link without the whole image being a link. [[Randall]] could have used this type of image map to make only the “Click here to take the survey” button be a link, and none of the rest of the image. But he cannot get the hang of it (or knowing his skills, does not wish to take the time to learn it). Not getting the hang of HTML image maps was also referenced on [http://imgs.xkcd.com/store/tour-news.png the banner for his book tour] from [http://web.archive.org/web/20140901023821/http://xkcd.com/ September 2014]

The title text is a joke off of {{w|Big Data}}, which is a name for analysis of a set of data that includes a huge amount of information. He also says "for a big planet" because the Earth is big.{{Citation needed}}

The survey is closed, and the questions replaced with the text: "The xkcd survey is now closed. Thank you for all your answers! Response data is being collected and will be posted soon." As of January 2019, the same caption is still there, with no indication of exactly how soon the data is intended to be posted. (Apparently, Randall crashed google forms, so the data is taking a long time to be retrieved [https://www.reddit.com/r/xkcd/comments/40mhve/what_ever_happened_to_the_survey_we_took/ (see this reddit thread)] - much like his breaking of [http://what-if.xkcd.com/imgs/a/62/balloon_wolfram.png Wolfram Alpha]] during answering a reader's question on [[what if?]])

==The Survey==
A recreation of the survey can be found [https://goo.gl/forms/CtAILwjyJAYsmqbO2 here on Google].

The recreation's data can be [https://goo.gl/5A77ZX found live here.]

It started with the following statement:

<nowiki>This is an anonymous survey. After it's done, a database of everyone's responses will be posted.
There's no specific reason for any of the questions. The goal is to create an interesting and unusual data set for people to play with. This is obviously not going to be a real random sample of people, but in the interest of getting cooler data, if you're sharing this with friends, try sending it to some people who wouldn't normally see this kind of thing!

WARNING: This survey is anonymous, but your answers WILL BE MADE PUBLIC. Depending what you write, it's possible that someone may be able to identify you by looking at your responses. None of these questions should ask about anything too private, but don't write anything that you don't want people to see. If you're not comfortable answering a question, just skip it.</nowiki>

Technical analysis is field which attempts to study stocks on the stock market statistically, seeking to profit off of the patterns that are found there.

The theoretical value of a stock is the sum of all its future earnings, with earnings in the future discounted appropriately to account for the [https://en.wikipedia.org/wiki/Time_value_of_money time value of money]. Because these earnings are never fully predictable, traders may have different ideas about the true value of a stock, and buy the stock if they believe the currently offered prices are particularly low, or sell it when the prices are high.

Technical analysis, however, does not even attempt to understand the earnings of the stock, instead focusing on the shapes and patterns that result from traders making their these moves. While there is a human behavioral component to stock trading, it is not clear that one can extract much information from the shapes of stock charts.

The comic displays a stock price chart, annotated with labels which purport to be technical analysis.

One label celebrates that "these two points define a line! Promising signal." (In Euclidian geometry, any two points define a line.)

The mouseover text raises a question of very talented people building systems to make themselves a lot of money without actually accomplishing anything worth money. This concern is perhaps not in and of itself about technical analysis, but more about the stock market and related trading ecosystems in general, in particular high speed traders. While is not always easy to understand why certain forms of market activity might be valuable, and hard to put a price tag on concepts like "risk," "liquidity" and "price discovery," sometimes people are just working to trick others into bad deals, or forcing market participants to pay them [https://en.wikipedia.org/wiki/Rent-seeking unearned money]. This may make the smart people a lot of money, but it does so by harming society, not helping it.

2097: Thor Tools

2019-01-14T19:36:33Z

162.158.63.232: /* List of tools */

{{comic
| number = 2097
| date = January 11, 2019
| title = Thor Tools
| image = thor_tools.png
| titletext = CORRECTION: After careful evaluation, we have determined that the axis label on this chart was printed backward.
}}

==Explanation==
{{incomplete|Add a list of the tools in the comic. Do NOT delete this tag too soon.}}

In Norse mythology, {{w|Thor}} is the name of a god of thunder and lightning. His signature weapon is a magic hammer called {{w|Mjölnir}}. In popular culture Thor might be best known for his role in {{w|Thor (Marvel Comics)|Marvel comics and films}}, which his appearance here seems to be referencing. In the Marvel Cinematic Universe movie, Avengers: Infinity War, Thor also wields an axe named Stormbreaker.

Although this hammer was historically a weapon, this comic interprets it as it would more commonly be interpeted today -- as a tool. The comic is listing various hand tools in order of utility and viability as Thor's weapon, besides his actual, enchanted hammer. Hammers are heavy, blunt, and can do large amounts of damage to an opponent, whereas a hand plane is sharp, but only in one place, and will only inflict surface wounds.

Some of these tools require power, which would generally require Thor to stay near an outlet or keep a battery charging, such as the circular saw, or Dremel. However, being the god of lightning may allow him to circumvent this, by producing electricity for the direct current (D.C.) tools, although he would need an inverter to convert the lightning (D.C.) to alternating current (A.C.) for the tools requiring it. Thor would also need compressed air for the nail gun or jackhammer, only allowing Thor so many shots before reloading the air tank at an outlet, or via a concentrated wind storm.

The nail gun and staple gun would also require nails or staples respectively to function as a weapon. Although Mjölnir is believed to return to Thor if thrown, it's not clear how similar system could work with nails and staples.

The usefulness of the nail gun as a weapon might depend on whether it was an older one that can be bump-fired or a newer one that requires a separate trigger pull for each nail.

In the title text, [[Randall]] writes that the order of the axis label should be reversed, making the plane the best tool and Mjölnir the worst. Considering that the title of the comic is "Thor Tools" ("tools", instead of "weapons"), the argument seems to be that a hammer is less useful than the rest, by seeing them as tools and not as weapons.

A few other interpretations of this could be:
* Randall proposes that Thor armed with a plane or digital calipers would be much more fearsome than with a hammer.
* The "value" of the more strange-seeming items would be much higher than his traditional hammer, perhaps more gory or more humorous.
* Thor tends to cause collateral damage, and would cause less with a plane or calipers.
* "Best" and "worst" are to be interpreted for Thor's enemies rather than Thor himself.
* Randall might just find the idea of Thor wielding a Plane as a weapon to be really funny.

The title may be a reference to Gary Larson's ''The Far Side'' comic, ''Cow Tools''.

===List of tools===

All shown tools are explained below:
;Hammer
:A {{w|hammer}} ''is a tool consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object''. Thor was a hammer-wielding god and produced the lighting by using this tool. A {{w|war hammer}} was an actual blunt weapon used for combat in medieval times, and is the original Thor's attribute. There exists a variety of craftsman's hammers designed for specific purposes which can be used as weapons of opportunity to various degrees, depending on the tool's size, weight and material.
;Axe
:An {{w|axe}} or just ax is another old human tool used to split and cut wood, but it also was used as a dangerous weapon in the medieval times. The battle-axes of old were of considerably different design than the woodworking ones, being lighter and having thinner and wider blades. A woodworking axe, though not designed for combat, could be a formidable weapon of opportunity.
;Claw hammer
:A {{w|claw hammer}} is a hammer tool primarily used for driving nails into other objects, but also for pulling nails from them. This item seems a bit redundant in the presence of a general hammer on the axis, but could be seen as more scary because it has a pointed, curved and split back head (used for pulling nails). In fact, the usefulness of its back head for combat is debatable at least. On the other hand, it is smaller and lighter than some other craftman's hammers, and less scary than a true war hammer, so its place on the axis may be justified.
;Circular saw
:A {{w|circular saw}} is using a, mostly electric powered, fast-revolving toothed disc to cut materials. A stationary version is called a ''table saw'' but the figure of Thor drawn above presents him using a lighter hand-held version making a buzzing sound. Since the power of the saw is far beyond the human power it is quite a dangerous tool and could be fatal to the user himself. However, it would be rather unwieldy in combat, as it is quite heavy and bulky, and usually requires both hands to operate. Also, electric circular saw would be limited by its cord length, however cordless (battery-operated) saws exist today. This item could be a mock reference to a common trope in horror movies or computer games, when a {{w|chainsaw}} (not a circular saw) is used a weapon.
;Shovel
:A {{w|shovel}} is also a historic tool. It can be used to dig into the ground, move snow or dirt, harvest, and much more. Because it has a relatively thin, sharp metal blade at the end of a pole, it can be used as a weapon of opportunity. Indeed, a small (sometimes foldable), sturdy {{w|Entrenching tool|spade}} was and still is a standard issue item for an infantryman in some countries, intended mainly for entrenching work, but also usable as a weapon – and the soldiers are trained to use it as such, sometimes to a high skill, specifically among special forces. It is rumored that Russian Spetznaz operators are specifically trained to use their spades as throwing weapons. It is therefore more useful in combat than a circular saw – but may be seen as less scary.
;Jackhammer
:A {{w|jackhammer}} is a power tool used to drill and crush hard but brittle materials like stone, concrete etc. It has heavy body with a protruding shaft that makes hard and rapid back-and-forth (and optionally also rotary) movements that drive an implement (a drill, a chisel etc.) into the worked material. Like the circular saw jackhammer is a tool that is powered far beyond single human capabilities. Most jackhammers are very heavy and can be reasonably used only in a facing-down position to work on floors, pavements and other near-horizontal surfaces, nullifying combat application. However, since Thor is purportedly very strong, he may be able to hold it horizontally for some combat...
;Socket wrench
:A handle attached to a {{w|socket wrench}} is mostly used to tighten bolts or nuts. But since it is quite heavy and resembles a hammer it could also be used in a similar fashion. It may be a self-reference to [[538: Security|comic 538]].
;Bolt cutters
:{{w|Bolt cutters}} are cutters with very long handles, typically 2 or 3 feet long, and comparatively tiny jaws. The length of the handles provides the user enough mechanical advantage to sheer through things like bolts, chain links, and lock shackles. Although this tool can cut some fairly tough objects, its usefulness in combat is limited – as far as the cutting action goes at least. On the other hand they are quite heavy and can be used as a blunt weapon.
;Hacksaw
:A {{w|hacksaw}} is a type of hand saw with very small teeth. Hacksaws are well suited to cutting materials like metal and plastic, where the larger teeth of a wood saw would tend to bind or damage the material around the cut. Hacksaw blades are fairly unlikely to seriously injure people, though a hacksaw may be useful against metal baddies like Ultron.
;Nail gun
:A {{w|nail gun}} is a tool for driving nails or other fasteners into various materials ranging from soft wood to hard concrete by a single powerful "shot" to the nail being driven. There are models powered by compressed air, electricity (several types of mechanisms) or explosive charges similar to firearm ammunition (most often compatible with {{w|.22 Short}} blank cartridges). They are normally used by slightly pushing the "nozzle" against an object, disengaging a safety nose contact mechanism, and pulling the trigger. These are quite dangerous tools and can be potentially modified – by removing safety mechanisms – to act similarly to a handgun, shooting nails as high-speed projectiles. It's place in the middle of the axis seems not right compared to the work hazard level of other tools placed left of it. If safety mechanisms are left intact, a nail gun would need to be used in close combat by pressing it against an opponent which would make it difficult to apply, but if applied successfully it would inflict grievous wounds.
;Staple gun
: A {{w|staple gun}} is a tool used to drive {{w|Staple (fastener)|staples}} (C-shaped pieces of hard wire) into relatively soft materials such as wood, plastics and light masonry in order to fix something to them. There exist spring-loaded hand-operated staple guns as well as power ones utilizing either electricity or compressed air. The power discharged during staple action is a lot less than that of a nail gun and would inflict minor skin wounds at most. If one manages to eject a staple into the air (not against an object) it won't travel very far. A figure of Thor is drawn above the axis showing him using a staple gun this way, with staples falling short onto the ground. The gun held by Thor makes ''kachunk'' sounds characteristic for a spring-loaded version of the tool.
;Coping saw
: A {{w|coping saw}} is a hand saw with a thin replaceable blade and is used to cut curves and shapes in wood or other relatively soft materials. While it could produce a surface wound and draw blood, a person would generally not stand still long enough to be seriously hurt by being sawed at by a coping saw, plus they could bend or break the blade relatively easily.
;Screwdriver (flat)
:A (flat) {{w|screwdriver}} is a metal rod with a handle, flattened and ground at the other end to form a fairly sharp but short edge perpendicular to the rod. It is normally used to drive {{w|Screw|screws}} into a material, by putting the edge into a groove on the screw's head and turning it while pressing firmly. It is not very dangerous normally, but many people have cut their fingers while driving screws in. It could potentially be used as a stabbing weapon similarly to a dagger, but much less effectively, or alternatively the heavy handle may be used as a bludgeon, though the smooth rod would be difficult to grip. Some nations seem to regard it so much dangerous as to ban its possession in public along knives.
;Ball-peen hammer
: Like a regular hammer, a {{w|Ball-peen hammer|ball-peen hammer}} has a flat head designed to hammer things like nail. However instead of the "claw" a regular carpenter's hammer has to pull out nails, it has a second head that is shaped like a ball and which is used to bang surfaces such as sheet metal directly. A ball-peen hammer probably the smallest of hammers, and usually used for more delicate work. Thor's Hammer has two flat surfaces for pounding (no claw), so a ball peen might be like a smaller Thor's Hammer and could be pretty deadly in his hands. The ball part would probably not be any more or less effective than the flat part, except it might bounce or deflect off some surfaces where a flat one might not.
;Screwdriver (Phillips)
:Similar to a flat screwdriver, but with a cross-shaped tip, designed to drive screws with matching cross-shaped heads. While a Phillips screwdriver could potentially be used as an improvised weapon to stab or strike like a flat screwdriver, the blunter, cross shape is less likely to inflict cutting injury, likely leading to its lower position on the list.
;Awl
:An {{w|Stitching awl|awl}} is a hand tool, basically a rather short, thin, sharp (sometimes curved) spike with a handle. It is used for punching holes through soft material (leather, fabrics) or to {{w|Scratch awl|mark points}} or lines on wood or metal to assist further work such as cutting or drilling. In a pinch, it could be used as a stabbing weapon like a dagger, but a screwdriver is more sturdy for such purpose.
;Digital Caliper
:{{w|Digital calipers}} are an instrument for precisely measuring the dimensions of small objects. Typically, digital calipers can measure inner diameters, outer diameters, and depth. The reason they are considered more formidable than Dremels and planes is likely how surprisingly sharp the calipers are. They need to be sharp to make accurate measurements, but it is not uncommon for people to cut themselves while using a digital caliper.
;Dremel
:Dremel is a brand name (often used in a generic sense) of small {{w|Die grinder|rotary power tools}} that can be used in precise work involving small objects such as engraving, milling, drilling, grinding, cutting, polishing etc. It consists of a relatively small and lightweight body housing a high-speed electric motor driving a shaft equipped with a {{w|Chuck (engineering)|chuck}}. Various implements can be fixed to the chuck – drills, milling cutters of various shapes, small cutting disks, grinding stones, brushes, soft polishing disks etc. Typically the tool is used handheld against an object held in a vice. It can also be mounted in a stand with a {{w|flexible shaft}} attached, at the other end of which an implement is fixed in a chuck, allowing for still more precise work. A Dremel would be rather useless in combat, effecting in superficial wounds only. It could be seen as a baby circular saw, therefore much less scary and placed much more to the right of the scale. However, it is still a heavy object with a firm grip, and could plausibly be wielded as a bludgeon, making it slightly more effective than a plane.
;Plane
:A {{w|Plane_(tool)|hand plane}} is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. It is designed to scrape layers of wood off the surface. While a plane does have a sharp edge and can cause painful injuries if misused, its awkward shape and the small size of the cutting edge would make it impractical to wield and nearly useless as a combat weapon, even for bludgeoning. A hand plane could plausibly be used as a particularly brutal ''torture'' device on a restrained victim, but as Thor is typically depicted as an honorable and heroic character it is unlikely that he would use one in this manner.

Talk:2087: Rocket Launch

2018-12-25T16:22:59Z

162.158.63.232:

I had to fight the urge to type Care Bare [[User:Arachrah|Arachrah]] ([[User talk:Arachrah|talk]])

This was published during the Arianespace launch livestream, between launch and satellite deployment: https://www.youtube.com/watch?v=mpHJoo0h8GQ [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 17:11, 19 December 2018 (UTC)

Looks like it could be an Ariane5 in the comic, it is a 3 stage. Anyone know if Max-CB is a real thing (and before I get any wisecracks, I know there aren't any Care Bears in the clouds) [[Special:Contributions/162.158.63.214|162.158.63.214]] 20:27, 19 December 2018 (UTC)

: A search for rocketry terminology reveals that Cb stands for Ballistic Coefficient, which is a measure of the ability to coast. It is related to both velocity and air density, which vary throughout a rocket launch, so it makes sense that there might be some point of maximum ballistic coefficient. (Note: I am not a rocket scientist, and this is clearly rocket science, so take this with a grain of salt!) [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 21:13, 19 December 2018 (UTC)
::That point is called "Max-Q". Source: I've seen a lot of rocket launches recently and they always mention it, because it's the second most likely moment to have a failure (first is the launch, of course). [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 07:28, 20 December 2018 (UTC)

: Pontificating further, it is reasonable to conjecture that as a rocket accelerates to higher speeds, the drag from the atmosphere increases with increasing speed, but past a certain point the drag begins to decrease as the air gets thinner. This suggests there is some point somewhere during the launch sequence where aerodynamic drag reaches a maximum value - aka Max Cb. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 21:26, 19 December 2018 (UTC)

: Finally one I can help with! Okay, I don't think this is ballistic coefficient for several reasons: 1. Ballistic Coefficient is typically noted by the greek letter Beta, not Cb. 2. Ballistic coefficient is mass divided by drag area (drag coefficient times reference area). Basically a shape parameter. So while the mass does change over the course of the flight (burning fuel), the drag area does not. Making this a somewhat useless parameter for a launch vehicle 3. Ballistic Coefficient is typically reported as a static parameter rather than a time-varying parameter, so "Max ballistic coefficient" is a rather unusual metric (and would occur on the launch pad in any case, when mass is highest). Finally, as an aside, objects with high ballistic coefficients tend to fly through the air easily and are not influenced very much by wind (such as rocks or bullets), whereas low-beta objects can by pushed and slowed down a lot by the wind (such as balloons). [[User:Tyanderson91|Tyanderson91]] ([[User talk:Tyanderson91|talk]]) 03:17, 20 December 2018 (UTC)
:: For rockets with side boosters, as the one shown, drag will potentially change dramatically at each staging event; when the side boosters are jettisoned they are no longer dragging on the rocket, and it's possible that the stage will have a higher ballistic coefficient because there's less surface area and not significantly less mass.

The max CB is clearly meant to spoof the real problem of rockets hitting birds. Since birds can't fly in the he upper part of the atmosphere, the point of highest likelihood of hitting a bird would presumably be below max-Q and not above it as in the comic. It is worth noting that there are no clouds at the altitude where max CB is shown in the comic, so it seems unlikely that any hypothetical cloud castle would be that high.

EDIT: ok, after checking the numbers it seems like it is technically possible to encounter birds and clouds at heights above max-Q for some rockets, but the position shown in the comic still seems too high.

Up until 1964 a litre (and therefore actually the metre too) used to be defined as the volume that water with mass 1kg takes. But this is not good for exact measurements not only because you need exactly reproducable temperature, pressure (not so problematic, because you can measure them and then calculate the divergence) and gravity (not so easy to measure, because you need an exact mass and exact masses are impossible to keep the same), but also because you need pure water free of any polutions of other stuff (hard and expensive) and even free of tiny amounts of isotopes which are deuterium and tritium (even way more expensive).
Because the water that was used then was never close to pure the actual weight of water nowadays is 0.99997kg at 4°C and 1.013bar and I don't know which value for g. There is also another definition which I like, but is hard to measure in real life scenarios: E=mc².

I'm guessing that they'll get around the varying g problem by defining the kg in terms of some standard acceleration equal to 9.81 m/s^2. Then when measuring an object's mass you would account for the difference between the local value of g and the standard one. This isnt a problem because we can measure gravitational acceleration quite precisely and it depends only on the units of length and time.

Up until 1964 a litre (and therefore actually the metre too) used to be defined as the volume that water with mass 1kg takes. But this is not good for exact measurements not only because you need exactly reproducable temperature, pressure (not so problematic, because you can measure them and then calculate the divergence) and gravity (not so easy to measure, because you need an exact mass and exact masses are impossible to keep the same), but also because you need pure water free of any polutions of other stuff (hard and expensive) and even free of tiny amounts of isotopes which are deuterium and tritium (even way more expensive).
Because the water that was used then was never close to pure the actual weight of water nowadays is 0.99997kg at 4°C and 1.013bar and I don't know which value for g. There is also another definition which I like, but is hard to measure in real life scenarios: E=mc². A kilogramm should be 1/c² of the mass which anything becomes heavier that you accelerate by the energy of one Joule. --[[Special:Contributions/162.158.90.150|162.158.90.150]] 17:11, 16 November 2018 (UTC)

So, you could theoretically visit the North Pole in late March and mid-September to have two days of 24-hour sunlight nearly 6 months apart. [[User:Nialpxe|Nialpxe]], 2017.

::It is also for this reason it says close to the equinoxes. At the equinoxes the sun sets for the first time in 6 months at one of the poles (rises at the other), splitting that 24 hour cycle in two times 12 hours of sun/no sun. And then it either stays up of stays down the next half a year. So if you come just after the sun rose and then again just before the sun sets on the North Pole you could get 24 hours sun shine with about a half year apart, but not completely. So this is White Hat's objection, although the title text also states that it doesn't have to be equally spaced. But in White Hat's opinion (of his teasing Cueball) it should be exactly half a year apart, and probably preferably on the two poles when the sun is highest at the Summer/Winter Solstices... ;-) --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:29, 20 October 2017 (UTC)
:Two details:
:a) The equinoxes are not exactly 6 months apart. The earths orbit is not circular. A daylight "day" at the south pole is about 9 days longer than at the north pole. There is a narrow window to pull off 24 hours of daylight six months apart using only the south pole, whether "6 months" is 6 calendar months or exactly half a year.
:b) Because sunrise and sunset (and direct sunlight) are defined by the upper limb of the sun and because of refraction polar, polar sunrise is about 3 days before the equinox and polar sunset is about 3 days after the next equinox. This widens the window at the south pole and just about makes it possible to do at the north pole.

Just to make sure, the "iron filings" part has no real use. Isn't it? --[[User:Lou Crazy|Lou Crazy]] ([[User talk:Lou Crazy|talk]]) 09:21, 20 October 2017 (UTC)
:Yes the two last advice has no meaning and also has no myth they are based on. The soap myth may be a problem if the coating is just oil based and could in principle be a problem with some old pans --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 09:29, 20 October 2017 (UTC)

You don't need to throw away pans if the seasoning gets messed up, just reseason them, in case of rust or extreme gunk attack it with an angle grinder until it is shiny. Use safety equipment! Then reseason it. [[User:BlakeFelix|BlakeFelix]] ([[User talk:BlakeFelix|talk]]) 12:23, 20 October 2017 (UTC)

It is my understanding that you don't want to use soap on a cast iron pan because the soap will get into the pores and cause any food you cook on it after that to taste like soap. [[Special:Contributions/172.68.54.34|172.68.54.34]] 14:26, 20 October 2017 (UTC)
:Nope. After the soap quickly comes rust, and to remove the rust, you have to scrub away the seasoning. If you did use soap, wipe the pan with an oily cloth afterwards. Or just use hot water and a brush. --[[Special:Contributions/162.158.88.92|162.158.88.92]] 17:29, 20 October 2017 (UTC)

So what is this a metaphor for? There's something you can't own unless other people believe you are taking good care of it, even if the care is nonsensical... The first thing I thought of was a baby, but that doesn't really seem likely to me. Any other ideas? [[User:Maplestrip|Maplestrip]] ([[User talk:Maplestrip|talk]]) 14:34, 20 October 2017 (UTC)
:It’s not a metaphor. There are people who are actually super fanatical (or pretentious) about cast iron pans.[[Special:Contributions/162.158.75.64|162.158.75.64]] 15:06, 20 October 2017 (UTC)
::Oh yes. And then there are people who very nearly faint every time someone with a butter knive comes close to their teflon pans. ;-) --[[Special:Contributions/162.158.88.92|162.158.88.92]] 17:35, 20 October 2017 (UTC)
