{{TOC}}
==Explanation==
{{w|Map projection}}, or how to represent the spherical Earth surface onto a flat support (paper, screen...) to have a usable map, is a long-time issue with very practical aspects (navigation, geographical shapes and masses visualization, etc.) as well as very scientific/mathematical ones, involving geometry or even abstract algebra among other things. There is no universal solution to this problem: Any 2D map projection will always distort in a way the spherical reality. Many projections have been proposed in various contexts, each intending to minimize distortions for specific uses (for nautical navigation, for aerial navigation, for landmass size comparisons, etc.) but having drawbacks from other points of view. Some of them are more frequently used than others in mass media and therefore more well-known than others, some are purely historical and now deprecated, some are very obscure, etc.

[[Randall]] suggests here the idea that someone's "favorite" map projection can reveal aspects of their personality, then goes through a series of them to show what they can mean.

He may actually believe that all map projections are in a way bad. This could be inferred from the fact that he much later began publishing a series of [[:Category:Bad Map Projections|Bad Map Projections]], starting with [[1784: Bad Map Projection: Liquid Resize]], which was Bad Map Projection #107 on his list, and was followed up by #79: [[1799: Bad Map Projection: Time Zones]]. The projections below could be #1-#12 on that list, although the last one, where Randall hates those that love it, might be somewhat further down the list.

===Mercator===
[[File:MercatorProjection.jpg|frame|The Mercator projection]]
The {{w|Mercator projection}} was introduced by Flemish cartographer Gerardus Mercator in 1569. The main purpose of this map is to preserve compass bearings; for example 13 degrees east of north will be 13 degrees clockwise from the ray pointing toward the top of the map, at every point. A mathematical consequence is the mapping is conformal, i.e. if two roads meet at a certain angle on the surface of the Earth, they will meet at that same angle on the map. It also follows that at every point the vertical and horizontal scales are the same, so locally i.e. considering only a small part of the map, geographical features (shapes, angles) are well represented, which helps a lot in recognizing them on-the-field, or for local navigation in that small part only. For this reason, that projection (or a close variant) is used in several online mapping services (such as Google Maps when this comic was published, but they switched to a globe, see below), which means that it is frequently encountered by the general public. A straight line on the map corresponds to a course of constant bearing (direction), which was very useful for nautical navigation in the past (and thus made that projection very well-known).

However, from a global point of view, this projection is radically incorrect in how it shows the size of landmasses (for instance, Antarctica and Greenland seem gigantic), and furthermore, it always excludes a small region around each pole (otherwise the map would be of infinite height), so it doesn't provide a complete solution for the problem of map projection. The comic implies that people who like that projection aren't very interested with map issues, and typically use what they are offered without thinking much about it.

===Van der Grinten===
[[File:VanDerGrintenProjection.jpg|frame|The Van der Grinten projection]]
The {{w|Van der Grinten projection}} is not much better than the Mercator. It was adopted by {{w|National Geographic}} in 1922 and was used until they updated to the Robinson projection in 1988.

The Van der Grinten projection is circular as opposed to the Mercator projection. The fictional person believes a circular map is more fitting to the real Earth's three-dimensional spherical nature because both are round. This belief fails to recognize that a two-dimensional circle has very little in common with the surface of a sphere, and thus this projection still causes a vast distortion of space and area. Because of this, Randall implies the Van der Grinten enthusiast to be optimistic and childishly simple-minded (e.g. "you like circles").

{{clear}}

===Robinson===
[[File:RobinsonProjection.jpg|frame|The Robinson projection]]
The {{w|Robinson projection}} was developed by {{w|Arthur H. Robinson}} as a map that was supposed to look nice and is often used for classroom maps. National Geographic switched to this projection in 1988, and used it for ten years, switching to the {{w|Winkel tripel projection|Winkel-Tripel}} in 1998.

{{w|The Beatles}} was a rock band that enjoyed great commercial success in the 1960s, and are widely considered the best act ever in the genre of popular music. The Beatles, coffee, and running shoes are all things that are very commonly enjoyed and largely uncontroversial, as well as being comforting. Liking these specific things suggests an ordinary, easygoing lifestyle paralleled by the projection.

{{clear}}

===Dymaxion===
[[File:DymaxionProjection.jpg|frame|The Dymaxion projection]]
Also called the Fuller Map, the {{w|Dymaxion map}} takes a sphere and projects it onto an icosahedron, that is a polyhedron with 20 triangular faces. It is far easier to unwrap an icosahedron than it is to unwrap a sphere into a 2D object and has very little skewing of the poles. {{w|Buckminster Fuller}} was an eccentric futurist who believed, for example, that world maps should allow no conception of "up" or "down". He was therefore more than happy to defy people's expectations about maps in the pursuit of mathematical accuracy.

Randall associates the projection to geek subculture and niche markets:
*{{w|Isaac Asimov}} was an American science-fiction writer, who (as well as publishing many textbooks) is considered the father of the modern concept of robots. He invented the {{w|Three Laws of Robotics}}. He also worked on more than 500 books throughout his career.
*{{w|XML}} is the eXtensible Markup Language. It is used to represent data in a format that machines can read and understand, as well as being human-readable. In practice, XML is cumbersome to read.
*{{w|Vibram FiveFingers|Toed shoes}} are a [[1065: Shoes|favorite]] of Randall's to pick on. In society they are seen as a {{w|geek}} clothing item.
*Brought to the world by {{w|Dean Kamen}}, the {{w|Segway PT}} was supposed to be a device that changed the way cities were built. In reality, most principalities have put in place rules specifically against Segways, making them a frustration to own and use within the law (in some states in Australia, it is illegal to use them on public footpaths or roads). Also, the former owner of {{w|Segway Inc.}}, the late {{w|Jimi Heselden}}, accidentally rode his Segway off a cliff in 2010.
*At the time of comic release, 3D goggles, nowadays widely known as {{w|Virtual reality headset|VR headsets}}, were considered a gimmick at best. The original idea is as old as 3D graphics, but it never really took off until mid-2010s. Earlier products were very unwieldy and offered poor graphics quality, so no one took this technology seriously.
*{{w|Dvorak Simplified Keyboard|Dvorak}} is an alternate keyboard layout to {{w|QWERTY}}. According to legend, QWERTY was invented to help keep manual typewriters from jamming (by placing the most used keys far from each other) but Dr. {{w|August Dvorak}} performed many studies and found the mathematically optimal keyboard layout to reduce finger travel for right handed typists. While some claim Dvorak is technically better than QWERTY, QWERTY had become the standard. All the keyboards were laid out in QWERTY format, but a lot of software exists to remap the keys to DVORAK for those interested in typing faster. Retraining the brain to use Dvorak takes perhaps a week. It has become a [[:Category:Dvorak|recurrent theme]] on xkcd.
**It seems likely that Randall looked at this comic when he made the [[1784: Bad Map Projection: Liquid Resize]], and given that he then released a comic about Dvorak, [[1787: Voice Commands]], the week after that, it seem like this old comic may also have inspired that Dvorak reference, see this [[1787: Voice Commands#Trivia|trivia item]].

===Winkel-Tripel===
[[File:Winkel-TripelProjection.jpg|frame|The Winkel Tripel projection]]
Proposed by Oswald Winkel in 1921, the {{w|Winkel tripel projection}} tried to reduce a set of three (German: Tripel) main problems with map projections: area, direction, and distance. The {{w|Kavrayskiy VII projection|Kavrayskiy projection}} is very similar to the Winkel Tripel and was used by the USSR, but very few in the Western world know of it.

The comic links this projection to {{w|hipster}} subculture. The hipster stereotype is to avoid conforming to mainstream fashions. "Post-" refers to a variety of musical genres such as {{w|post-punk}}, {{w|post-grunge}}, {{w|post-minimalism}}, etc. that branch off of other genres.

;Trivia
In German "Winkel-Tripel-Projektion" means Winkel's triple projection, and therefore the hyphen shouldn't be there: "Winkel Tripel" or "Winkel tripel".

===Goode Homolosine===
[[File:GoodeHomolosineProjection.jpg|frame|The Goode Homolosine projection]]
The {{w|Goode homolosine projection}} takes a different approach to skewing a sphere into a roughly circular surface. An orange peel can be taken from an orange and flattened with fair success; this is roughly the procedure that {{w|John Paule Goode}} followed in creating this projection. Randall is suggesting that people who like this map also prefer relatively easy solutions to other things in life, despite those solutions having nuanced problems that are more difficult to address.

Common people make arguments that if normal people would run the United States, then the US wouldn't be in the trouble it is. This is from the belief that career politicians are simply out to make money and will only act in the interest of their constituency when their continued easy life is threatened (usually around election time).

Airline food is another, much maligned, problem. How do you store enough food to feed people on long airplane trips? What kind of food can be served in an enclosed, low-air-pressure environment? The common solution is to use some kind of prepackaged, reheated meal. Randall is saying that the people in favor of the Goode Homolosine wonder why the airlines don't simply order meals from the restaurants in the airport, store that food, and serve it, rather than using bland reheated food.

Older cars burned oil like mad fiends, and oil back then would become corrosive to the innards of an engine, so oil had to be changed often. But, with the introduction of synthetic motor oil and better designed engines, new cars only need their oil changed about every 10,000 to 15,000 miles. A common conspiracy theory is that modern automobile oil manufacturers still recommend that car owners change their oil every 3,000-5,000 miles to "drum" up more business, even though that frequency is unnecessary.

All of these references suggest that people who like the Goode Homolosine projection are fans of easy solutions to problems. However, the solutions would not necessarily work in practice. For instance: the restaurants might have trouble making enough food for the whole plane, and it could get cold before being served; the air conditions [http://www.nbcnews.com/health/one-reason-airline-food-so-bad-your-own-tastebuds-6C10823522 aboard planes] can affect taste, so airlines say they optimize for this; there is no such thing as a "normal" person, and if there were, he/she would have virtually no chance at actually getting into government office; and the Goode Homolosine projection, while mostly resembling a flattened orange peel as suggested by the earlier analogy, does indeed cut down on distortion, but also has serious problems of its own, such as leaving huge gaps of nothingness between the continents, making distances across the oceans difficult to visualize.

===Hobo–Dyer===
[[File:Hobo-DyerProjection.jpg|frame|The Hobo–Dyer projection]]
The {{w|Hobo–Dyer projection}} was commissioned by Bob Abramms and Howard Bronstein and was drafted by Mick Dyer in 2002. It is a modified {{w|Behrmann projection}}. The goal was to be a more visually pleasing version of the Gall–Peters.

As is discussed in the Gall–Peters explanation, the Gall–Peters was developed to be equal area, so that economically disadvantaged areas can at least take comfort in the fact that their country is represented correctly by area on maps.

Randall associates the Hobo–Dyer projection to "crunchy granola" — a stereotype associated with vegetarianism, environmental activism, anti-war activism, liberal political leanings, and some traces of {{w|hippie}} culture.

With feminism becoming mainstream and alternative genders being more widely accepted, some have begun to invent gender-neutral pronouns so that when referring to a person whose gender is not known they cannot be offended by being referred to by the wrong pronouns. In {{w|Middle English}} 'they' and 'their' were {{w|Singular they|accepted genderless pronouns that could replace 'he', 'she'}} as well as be used to represent a crowd, but this usage is considered by some to be grammatically incorrect because of the plural/singular debate ([http://www.merriam-webster.com/video/0033-hisher.htm stupid Victorian Grammarians!]). There have been {{w|gender-neutral pronoun#Invented pronouns|many attempts at popularizing invented gender-neutral pronouns}} and they are beginning to achieve some degree of success in the mainstream.

{{clear}}

===Plate Carrée===
[[File:PlateCarreeProjection.jpg|frame|The Plate Carrée projection]]
Also known as the {{w|Equirectangular projection}}, it has been in use since, apparently, 100 AD. The benefit of this projection is that latitude and longitude can be used as x,y coordinates. This makes it especially easy for computers to graph data on top of it.

According to the comic, the projection appeals to people who find much beauty in simplicity.

{{clear}}

===A Globe!===
[[File:GlobeProjection.jpg|frame|The Globe "projection"]]
In any good discussion there has to be at least one smart-ass. This is a comic about map projections, that is, the science of taking a sphere and flattening it into 2 dimensions. The smart-ass believes that we shouldn't even try: a sphere is, tautologically, the perfect representation of a sphere.

To quote ''{{w|The Princess Bride}}'': "Yes, you're very smart. Shut up."

A globe is, of course, the "map projection" used by {{w|Google Earth}}, and recently by other mapping software (including Google Maps) as computers and phones get increasingly powerful 3D graphics.

{{clear}}

===Waterman butterfly===
[[File:WatermanButterflyProjection.jpg|frame|The Waterman Butterfly projection]]
Similar to the Dymaxion, the {{w|Waterman butterfly projection}} turns a sphere into an octahedron, and then unfolds the net of the octahedron, which was devised by mathematician {{w|Waterman polyhedron|Steve Waterman}} based upon the work of {{w|Bernard J.S. Cahill}}.

Bernard Cahill published a [http://www.genekeyes.com/B.J.S._CAHILL_RESOURCE.html butterfly map] in 1909. Steve Waterman probably has the only extant "ready to go" map following the same general principles, though Gene Keys may not be far behind. Waterman has a poem with graphics in a similar vein to this xkcd comic that is worth reading.[http://web.archive.org/web/20120118095915/http://watermanpolyhedron.com/worldmap.html]

[http://www.progonos.com/furuti/MapProj/Normal/ProjPoly/projPoly2.html Polyhedral projections] like Cahill, Dymaxion or Waterman typically offer better accuracy of size, shape and area than flat projections, at the expense of compass directionality, connectedness, and other complications.

The joke is that the person responding deeply understands map projections; anyone who knows of this projection is a person that Randall would like to get to know.

{{clear}}

===Peirce quincuncial===
[[File:PeirceQuincuncialProjection.jpg|frame|The Peirce Quincuncial projection]]
The {{w|Peirce quincuncial projection}} was devised by {{w|Charles Sanders Peirce}} in 1879 and uses {{w|complex analysis}} to make a {{w|conformal mapping}} of the Earth, that conforms except for four points which would make up the midpoints of sides and lie on equator (the equator is represented by a square and the corners connect the sides in the middle.)

{{w|Inception}} was a 2010 movie about {{w|meta}} {{w|lucid dream}}ing. It has a complex story that is difficult to follow and leaves the viewer with many questions at the end, and almost needs to be watched multiple times to be understood.

The human brain is not well developed to deal with oddly obvious things. One example is that everyone has a skeleton, but everyone is surprised to see a part of their body represented by an X-ray. Another is the fascinating complexity of the human hand, a machine which is amazingly complex, driven by a complex interplay of electrical and chemical signals; yet is the size of the hand and so useful. A fascination with or fixation on [http://tvtropes.org/pmwiki/pmwiki.php/Main/ContemplatingYourHands such thoughts] is often associated with an altered state of mind brought on by marijuana consumption. Therefore, Randall may be implying that this map would appeal to stoners.

{{clear}}

===Gall–Peters===
[[File:Gall-PetersProjection.jpg|frame|The Gall–Peters projection]]
The {{w|Gall–Peters projection}} is mired in controversy, surprisingly for a map. {{w|James Gall}}, a 19th-century clergyman, presented this projection in 1855 before the {{w|British Association for the Advancement of Science}}. In 1967, the filmmaker {{w|Arno Peters}} created the same projection and presented it to the world as a "new invention" that put poorer, less powerful countries into their rightful proportions (as opposed to the Mercator). Peters played the marketing game and got quite a few followers of his map by saying it had "absolute angle conformality," "no extreme distortions of form," and was "totally distance-factual" in an age when society was very concerned about social justice. All of these claims were in fact false. The Mercator projection distorts size in favor of shape, and Gall-Peters distorts shape in favor of size, being especially inaccurate at the equator and the poles.

Anyone who loves such a politically charged map that has become popular by way of marketing stunts, Randall would rather not have anything to do with.

===Title text===
The title text makes a joke that goes to the familiar meme from ''{{w|CSI: Miami}}'', in which the star, David Caruso starts a sentence, then puts on his sunglasses and ends the sentence with a corny pun. In this case, the pun is on {{w|map projection}} and {{w|projection (psychology)|projection}} in psychology. Psychological projection is an unconscious defense mechanism wherein a person who is uncomfortable with their own impulses denies having them and attributes them to other people, and blames these people for these impulses. The Sunglasses internet meme has been used [[:Category:Puts on sunglasses|in other comics]] as well.

2048: Curve-Fitting

2019-02-04T17:52:23Z

162.158.126.40: /* Cauchy-Lorentz (title text) */

{{comic
| number = 2048
| date = September 19, 2018
| title = Curve-Fitting
| image = curve_fitting.png
| titletext = Cauchy-Lorentz: "Something alarmingly mathematical is happening, and you should probably pause to Google my name and check what field I originally worked in."
}}

==Explanation==

An illustration of several plots of the same data with {{w|Curve fitting|curves fitted}} to the points, paired with conclusions that you might draw about the person who made them. These data, when plotted on an X/Y graph, appear to have a general upward trend, but the data is far too noisy, with too few data points, to clearly suggest any specific growth pattern. In such a case, many different mathematical and statistical models ''could'' be presented as roughly fitting the data, but none of them fits well enough to compellingly represent the data.

When modeling such a problem statistically, much of the work of a data scientist or statistician is knowing which fitting method is most appropriate for the data in question. Here we see various hypothetical scientists or statisticians each applying their own interpretations to the exact same data, and the comic mocks each of them for their various personal biases or other assorted excuses. In general, the researcher will specify the form of an equation for the line to be drawn, and an algorithm will produce the actual line.

Nonetheless scientists work much more seriously on the reliability of their assumptions by giving a value for the {{w|Standard deviation|standard deviation}} represented by the Greek letter sigma σ or the Latin letter s as a measure to quantify the amount of variation of the data points against the presented ''best fit''. If the σ-value isn't good enough an interpretation based on a specific fit wouldn't be accepted by the science community.

Since [[Randall]] gives no hint about the nature of the used data set - same in each graph - any fitting presented doesn't make any sense. The graphs could represent a star map, the votes for the latest elected presidents, or your recent invoices on power consumption. This comic just exaggerates various methods on interpreting data, but without the knowledge of the matter in the background nothing makes any sense.

===Linear===
[[File:Anscombe's quartet 3.svg|thumb|200px|Different data sets result in the same regression.]]
<math>f(x) = mx + b</math>

{{w|Linear regression}} is the most basic form of regression; it tries to find the straight line that best approximates the data. As it's the simplest, most widely taught form of regression, and in general derivable function are locally well approximated by a straight line, it's usually the first and most trivial attempt of fit.

The picture to the right shows how totally different data sets can result into the same line. It's obvious that some more basics about the nature of the data must be used to understand if this simple line really does make sense.

The comment below the graph ''"Hey, I did a regression."'' refers to the fact that this is just the easiest way of fitting data into a curve.

===Quadratic===
<math>f(x) = ax^2 + bx + c</math>

{{w|Polynomial regression|Quadratic fit}} (i.e. fitting a parabola through the data) is the lowest grade polynomial that can be used to fit data through a curved line; if the data exhibits clearly "curved" behavior (or if the experimenter feels that its growth should be more than linear), a parabola is often the first, easiest, stab at fitting the data.

The comment below the graph ''"I wanted a curved line, so I made one with math."'' suggests that a quadratic regression is used when straight lines no longer satisfy the researcher, but he still wants to use simple math expression. Quadratic correlations like this are mathematically valid and one of the simplest kind of curve in math, but this curve doesn't appear to satisfy the data any better than does simple, linear regression.

===Logarithmic===
[[File:Logarithm_plots.png|thumb|200px|Common logarithm functions.]]
<math>f(x) = a\log_b(x)</math>

A {{w|Logarithm|logarithmic}} curve growths slower on higher values, but still grows without bound to infinity rather than approaching a horizontal {{w|asymptote}}. The small ''b'' in the formula represents the base which is in most cases ''{{w|e (mathematical constant)|e}}'', 10, or 2. If the data presumably does approach a horizontal asymptote then this fit isn't an effective method to explain the nature of the data.

The comment below the graph ''"Look, it's tapering off!"'' builds up the impression that the data diminishes while under this fit it's still growing to infinity, only much slower than a linear regression does.

===Exponential===
[[File:Exponential.svg|thumb|200px|Exponential growth (green) compared to other functions.]]
<math>f(x) = a\cdot b^x</math>

An {{w|Exponential growth|exponential curve}}, on the contrary, is typical of a phenomenon whose growth gets rapidly faster and faster - a common case is a process that generates stuff that contributes to the process itself, think bacteria growth or compound interest.

The logarithmic and exponential interpretations could very easily be fudged or engineered by a researcher with an agenda (such as by taking a misleading subset or even outright lying about the regression), which the comic mocks by juxtaposing them side-by-side on the same set of data.

The comment below the graph ''"Look, it's growing uncontrollably!"'' gives an other frivolous statement suggesting something like chaos. Also this even faster growth is well defined and has no asymptote at both axes.

===LOESS===
A {{w|Local regression|LOESS fit}} doesn't use a single formula to fit all the data, but approximates data points locally using different polynomials for each "zone" (weighting differently data points as they get further from it) and patching them together. As it has much more degrees of freedom compared to a single polynomial, it generally "fits better" to any data set, although it is generally impossible to derive any strong, "clean" mathematical correlation from it - it is just a nice smooth line that approximates well the data points, with a good degree of rejection from outliers.

The comment below the graph ''"I'm sophisticated, not like those bumbling polynomial people."'' emphasis this more complicated interpretation but without a simple mathematical description it's not very helpful to find academic descriptions on the underlying matter.

===Linear, No Slope===
<math>f(x) = c</math>

Also known as a constant function, since the function takes on the same (constant) value ''c'' for all values of ''x''. The value of ''c'' can be determined simply by taking the average of the ''y''-values in the data.

Apparently, the person making this line figured out pretty early on that their data analysis was turning into a scatter plot, and wanted to escape their personal stigma of scatter plots by drawing an obviously false regression line on top of it. Alternatively, they were hoping the data would be flat, and are trying to pretend that there's no real trend to the data by drawing a horizontal trend line.

The comment below the graph ''"I'm making a scatter plot but I don't want to."'' is probably done by a student who isn't happy with their choice of field of study.

===Logistic===
[[File:Logistic-curve.svg|thumb|200px|A standard logistic function between the values ''0'' and ''1''.]]
The {{w|Logistic regression|logistic regression}} is taken when a variable can take binary results such as "0" and "1" or "old" and "young".

The curve provides a smooth, S-shaped transition curve between two flat intervals (like "0" and "1").

The comment below the graph ''"I need to connect these two lines, but my first idea didn't have enough math."'' implies the experimenter just wants to find a mathematically-respectable way to link two flat lines.

===Confidence Interval===
Not a type of curve fitting, but a method of depicting the predictive power of a curve.

Providing a confidence interval over the graph shows the uncertainty of the acquired data, thus acknowledging the uncertain results of the experiment, and showing the will not to "cheat" with "easy" regression curves.

The comment below the graph ''"Listen, science is hard. But I'm a serious person doing my best."'' is just an honest statement about this uncertainty.

===Piecewise===
Mapping different curves to different segments of the data. This is a legitimate strategy, but the different segments should be meaningful, such as if they were pulled from different populations.

This kind of fit would arise naturally in a study based on a regression discontinuity design. For instance, if students who score below a certain cutoff must take remedial classes, the line for outcomes of those below the cutoff would reasonably be separate from the one for outcomes above the cutoff; the distance between the end of the two lines could be considered the effect of the treatment, under certain assumptions. This kind of study design is used to investigate causal theories, where mere correlation in observational data is not enough to prove anything. Thus, the associated text would be appropriate; there is a theory, and data that might prove the theory is hard to find.

One notable time this is used is when a researcher studying housing economics is trying to identify housing submarkets. The assumption is that if two proposed markets are truly different, they will be better described using two different regression functions than if one were to be used.

The additional curved lines visible in the graph are the kind of confidence intervals you'd get from a simple OLS regression if the standard assumptions were valid. In the case of two separate regressions, it would be surprising if all those assumptions (that is, i.i.d. Normal residuals around an underlying perfectly-linear function) were in fact valid for each part, especially if the slopes are not equal.

A classical example in physics are the different theories to explain the black body radiation at the end of the 19th century. The {{w|Wien approximation}} was good for small wavelengths while the {{w|Rayleigh–Jeans law}} worked for the larger scales (large wavelength means low frequency and thus low energy.) But there was a gap in the middle which was filled by the {{w|Planck's law}} in 1900.

The comment below the graph ''"I have a theory, and this is the only data I could find."'' is a bit ambiguous because there are many data points ignored. Without an explanation why only a subset of the data is used this isn't a useful interpretation at all. As a matter of fact, with the extra degrees of freedom offered by the piecewise regression, it could indicate that the researcher is trying to fit the data to confirm their theory, rather than building their theory off of the data.

===Connecting lines===
This is often used to smooth gaps in measurements. A simple example is the weather temperature which is often measured in distinct intervals. When the intervals are high enough it's safe to assume that the temperature didn't change that much between them and connecting the data points by lines doesn't distort the real situation in many cases.

The comment below the graph ''"I clicked 'Smooth Lines' in {{w|Microsoft Excel|Excel}}."'' refers to the well known spreadsheet application from {{w|Microsoft Office}}. Like other spreadsheet applications it has the feature to visualize data from a table into a graph by many ways. "Smooth Lines" is a setting meant for use on a {{w|line graph}}, a graph in which one axis represents time; as it simply joins up every point rather than finding a sensible line, it is not suitable for regression.

===Ad-Hoc Filter===
Drawing a bunch of different lines by hand, keeping in only the data points perceived as "good". Not really useful except for marketing purposes.

The comment below the graph ''"I had an idea for how to clean up the data. What do you think?"'' admits that in fact the data is whitewashed and tightly focused to a result the presenter wants to show.

===House of Cards===
Not a real method, but a common consequence of misapplication of statistical methods: a curve can be generated that fits the data extremely well, but immediately becomes absurd as soon as one glances outside the training data sample range, and your analysis comes crashing down "like a house of cards". This is a type of ''overfitting''. In other words, the model may do quite well for (approximately) {{w|Interpolation|interpolating}} between values in the sample range, but not extend at all well to {{w|Extrapolation|extrapolating}} values outside that range.

''Note:'' Exact polynomial fitting, a fit which gives the unique <math>(n-1)</math>th degree polynomial through <math>n</math> points, often display this kind of behaviour.

The comment below the graph ''"As you can see, this model smoothly fits the- wait no no don't extend it AAAAAA!!"'' refers to a curve which fits the data points relatively well within the graph's boundaries, but beyond those bounds fails to match at all.

The name is also a reference to the TV show ''{{w|House of Cards (U.S. TV series)|House of Cards}}''. The plot in House of Cards began with a premise of a rise to power in the United States government, but as it continued into more seasons the premise was taken to an extreme, introducing more and more ridiculous plot points ("WAIT NO, NO, DON'T EXTEND IT!").

===Cauchy-Lorentz (title text)===
{{w|Cauchy_distribution|Cauchy-Lorentz}} is a continuous probability distribution which does not have an expected value or a defined variance. This means that the law of large numbers does not hold and that estimating e.g. the sample mean will diverge (be all over the place) the more data points you have. Hence very troublesome (mathematically alarming).

Since so many different models can fit this data set at first glance, Randall may be making a point about how if a data set is sufficiently messy, you can read any trend you want into it, and the trend that is chosen may say more about the researcher than about the data. This is a similar sentiment to [[1725: Linear Regression]], which also pokes fun at dubious trend lines on scatterplots.

A brief Google search reveals that Augustin-Louis Cauchy originally worked as a junior engineer in a managerial position. Upon his acceptance to the Académie des Sciences in March 1816, many of his peers expressed outrage. Despite his early work in "mere" engineering, Cauchy is widely regarded as one of the founding influences in the rigorous study of calculus & accompanying proofs. Notably, his later work included theoretical physics, and Lorentz was also a well-known physicist. Therefore, the title-text may be referring back to [[793: Physicists]].

Alternately, the title-text could be implying that the person who applied the Cauchy-Lorentz curve-fitting method may not be well qualified to the task assigned.

==Trivia==
*This is the comic 2048, or 211. In addition to being the name of a popular app referenced in [[1344: Digits]], this is an extremely round number in binary (100,000,000,0002). [[1000: 1000 Comics]] pointed out that comic 1024 would be a round number, but there were not any comics noting 2048.

*This comic is similar to [[977: Map Projections]] which also uses a scientific method not commonly thought about by the general public to determine specific characteristics of one's personality and approach to science.

*Regressions have been the subject of several previous comics. [[1725: Linear Regression]] was about linear regressions on uncorrelated or poorly correlated data. [[1007: Sustainable]], [[1204: Detail]] and [[1281: Minifigs]] depict linear regressions on data that was actually logistic, leading to bizarre extrapolations. [[605: Extrapolating]] shows a line extrapolating from just two data points.

Talk:2105: Modern OSI Model

2019-01-30T20:19:45Z

162.158.126.40: Arguing about Jenga

Randall seems to be saying that a startup doesn't need to create a new computer system to service their customers, all they have to do is put up a Facebook page which uses Google to find products and then has Amazon deliver them. The middle layer "Transport" is a joke because Amazon literally ships physical boxes, but the OSI model is not about actual boxes; it's about information and the way the information is presented to the user vs what goes on behind the scenes.
But I don't get the part about the horcruxes. Is it just the fact that there are seven of them? Or is there some subtle connection I'm missing here? [[Special:Contributions/162.158.106.180|162.158.106.180]] 05:50, 30 January 2019 (UTC)
: 'Transport' has nothing to do with Amazon, in this case, though the juxtaposition is amusing; also, the networking model has nothing to do with the user interface. The seven layers are from the 'standard' [https://en.wikipedia.org/wiki/OSI_model OSI networking model], which was introduced in the late 1970s to describe how networking systems work (or were expected to at the time). In practice, the [https://en.wikipedia.org/wiki/Internet_protocol_suite#Key_architectural_principles Internet Protocol Suite] model is used, which has more or less the same ideas despite evolving separately, though with only four formal layers (Link, Internet, Transport, and Application) instead of seven (Physical, Data Link, Network, Transport, Session, Presentation, and Application).
:In the OSI model, the Transport layer is Layer 4 (going up from the lowest level, Physical) and represents the part responsible for checking the consistency of data delivery - that is to say, it decides whether or not to check for dropped packets, and whether to resend dropped ones. In the actual Internet model, the rough equivalent is the [https://en.wikipedia.org/wiki/Transmission_Control_Protocol Transmission Control Protocol] (for 'connected' transmissions which do check and resend) and [https://en.wikipedia.org/wiki/User_Datagram_Protocol User Datagram Protocol] (for 'connectionless' ones which don't). [[Special:Contributions/172.68.78.10|172.68.78.10]] 16:29, 30 January 2019 (UTC)

:(Spoilers alert) Voldemort uses signifying objects of his life, heritage and his school's founders as horcruces. When the OSI layers are used as horcruces, one problem would be that Google/Amazon would have taken control of two horcruces, the other that some of the layers are frayed at the sides. Randall should not have put his horcruces in living standards - that was a very dangerous move. Sebastian --[[Special:Contributions/172.68.110.46|172.68.110.46]] 07:54, 30 January 2019 (UTC)

Is there a meaning of the widths of the layers - not a block or a triangle/pyramid? Are there more layers than the named ones? Or the named ones multiple times? This would correspond to the design of ever more layers, virtualizations, abstractions and overall complexity of computer systems as time moved forward. Sebastian --[[Special:Contributions/172.68.110.46|172.68.110.46]] 07:49, 30 January 2019 (UTC)
:It looks like a jenga tower to me. [[Special:Contributions/162.158.89.223|162.158.89.223]] 12:35, 30 January 2019 (UTC)
:: Could some reference to this, or at least some speculation on the irregularity of the tower on general, be added? I would propose something like the following:
::: ''The significance of the irregular pattern of the Google/Amazon blob isn't clear. It is likely that it is in reference to the irregular way in which their modifications to the OSI stack have evolved. However, it is also notable that the irregular structure of the stack is arranged so as to resemble a [https://en.wikipedia.org/wiki/Jenga Jenga] tower. Jenga, for those unfamiliar, is a game in which blocks are added and removed from a vertical pile until the whole collapses. This may be a commentary on the instability of the stack in general, or on how Google and Amazon's additions and changes to it have destabilized the networking protocols.'' -- [[Special:Contributions/172.68.78.10|172.68.78.10]] 16:00, 30 January 2019 (UTC)
::::I think you may be reading too much into the shape, it looks much more irregular than a Jenga tower. If anything I would guess it's just a rough reflection of how much influence Google and Amazon have at each level -- more Google influence means the blob goes farther left, more Amazon influence means it goes farther right.

I think Google & Amazon are the grey blob that is slowly absorbing all of the layers [[Special:Contributions/141.101.107.114|141.101.107.114]] 07:55, 30 January 2019 (UTC)
: Excellent remark! Google & Amazon are inserted between the Data Link and Network layers, and while it seems like an eight layer from the shape profile, they do not sit in their own bordered rectangle. Another view point is maybe Randall tried to display the fight between the Infrastructure providers to capture a new layer in gestation. [[Special:Contributions/141.101.107.114|141.101.107.114]] 08:21, 30 January 2019 (UTC)

: Agreed. There is no way that Randall wanted the label for the gray blob to just apply to a couple of layers. It's clearly labeling the entire gray blob as "Google and Amazon". Otherwise, he would have put in another dividing line or two. So all the glue between the layers is being described as "Google and Amazon". Meaning that the layers wouldn't even be able to talk to each other and function correctly without G+A glue between them. Maybe this is "glue" in the technical sense of trivial code which converts from one API to another. The basic point here is that Google lays cable in some places and writes Chrome and owns You Tube, so it's definitely at both ends. I'm not sufficiently knowledgeable to say if it owns/writes stuff in the middle. And I'd be surprised if this was true of Amazon. But it's not my place to comment on the veracity of Randall's remarks, I'm just trying to sort out what he's saying.

: That's how I understood it as well. By having there hands in *everything* G+A defeat the whole purpose of having a layered (ie. divided) model, making the 'modern model' just bits and pieces added to G+A code.

Trivia: (Major Spoiler alert) Voldemort originally intended to create six horcruces to divide his soul into 7 (including his own body) pieces. The 6th unintended horcrux is Harry Potter by Voldemort killing his parents. Later on after his revival Voldemort made the snake Nagini to his seemingly 6th horcrux, which was actually his 7th. Does that mean Randall embodies one of the OSI layers from the beginning of his existence? :-) Sebastian --[[Special:Contributions/172.68.110.46|172.68.110.46]] 08:01, 30 January 2019 (UTC)

Just a point of contention with the current explanation. Right now, Google and Facebook are two of the major players in cloud-based computing: I have seen tutorials on leveraging Google's cloud services to home-brew your own proxy service.
As such, a lot of internet services are running ON Google or Amazon, so Google and Amazon DO effectively own, or at least manage, several layers.
I do not know if Facebook is one of those, and I would tend to doubt it, considering its size.

Why does the bot have seven layers???

PRESENTATION, SESSION, and NETWORK are not contained within GOOGLE & AMAZON the way the rest of the layers are; there are openings to the outside for those three.

To really change Earth to be either like Venus or Mars we need to get rid of the magnetic field that stops the solar wind stripping the atmosphere away. Once that is depleted the oceans will evaporate so that the solar wind can strip that away as well. Whether Earth then freezes or boils would depend on surface rocks and volcanic activity levels. One option to stop the magnetosphere would be to de-orbit the Moon, thus re-amalgamating it with the Earth and getting lots of vulcanism going.

}}

==Explanation==
{{incomplete| Comic is still undergoing TECHNICAL ANALYSIS (this is just the prologue). Do NOT delete this tag too soon.}}

There are two recognized methods to attempt to predict the stock market, each with its own pros and cons:

*{{w|Technical analysis}} is more appropriate for traders seeking to benefit off short-term fluctuations in stock prices, by attempting to look for trends, momentum, patterns etc. in the stock prices.
*{{w|Fundamental analysis}} is more appropriate for investors seeking to benefit off long-term fluctuations in stock prices, by attempting to guess future earnings based on some fundamental factor about the stock. Investors can choose to look for good Price/Earnings ratio or other indications that a stock may be a solid investment.

[http://www.investopedia.com/terms/r/randomwalktheory.asp Random Walk theory] suggests that neither of these methods are particularly useful at predicting the future of the stock market (see link for a funny story about dart throwing monkeys).

The theoretical value of a stock is its [https://en.wikipedia.org/wiki/Net_present_value net present value] which is the sum of all its future earnings, with earnings in the future discounted appropriately to account for the {{w|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 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. To the extent it does work, a substantial part of its success may be simply an artifact of the herd behavior of traders who engage in technical analysis, a zero-sum game.

The comic displays a {{w|Candlestick chart|stock price chart}}, annotated with labels which purport to be technical analysis. These labels are nonsense from the perspective of technical analysis, but do accurately describe the graph itself: "{{w|allegro}}" (a musical term used to set the tempo at the beginning of a score), "{{w|prologue}}" (an introductory section of a play, book, or similar), "{{w|lumbar}} support" (the thing in a chair shaped to better support your back), "bathtub" (possibly a reference to the so-called "{{w|Bathtub curve}}"), "{{w|uptalk}}" (a speech pattern). One label celebrates that "these two points define a line! Promising signal." (In geometry, any two points define a line.)

The shape of the chart is similar to the exponential behavior of cryptocurrencies when they are successful, where price (positional height on the chart) roughly increases while volatility (height of the bars or candles themselves, and of the peaks and troughs, on the chart) does the same. Technical analysis used to be an esoteric domain held by well-paid stock analysts, but as cryptocurrency has spread and taken down the many barriers to engaging in investment trading, people from all walks of life have begun staring at charts like this.

{| class="wikitable"
|+Graph labels and possible meanings
|-
|{{w|Allegro_(music)|Allegro}}
|Tempo notation in music: played quickly and brightly (translation from Italian: cheerful, lively) - a series of very small changes in this region of the graph might suggest notes played quickly
|-
|Prologue
|A prologue is an introduction to a book or other work; this presumably refers to the initial period of minimal growth which is moving toward a much more active period
|-
|Decline
|Describes a negative trend
|-
|Doldrums
|A stagnant section of the graph with little movement
|-
|Spline
|A {{w|Spline (mathematics)|spline}} is a mathematical means of generating a smooth curve, referring to the smoothed curve shown here
|-
|{{w|Lumbar}} Support
|A cushion or other device that provides support to the lower part of the ''spine'', a play on the preceding ''spline''
|-
|Renewal
|Strong upward trend; also might suggest the growth of green bars, like greening up in the spring
|-
|Hmm!
|The three circles this label points to mark periods of growth that immediately preceded a decline. Ideally for someone performing a technical analysis, if such occurrences can be foreseen accurately it would be a major boon for the stockholder, as they could be tipped to sell it right away before the price drops and net a cash profit.
|-
|Hark! The cliffs!
|A long bar suggesting a steep cliff
|-
|Declination
|A term which sounds similar to decline, but actually refers to the angular distance of a point from one of the poles. The declination of magnetic north is used to correct the difference between true and magnetic north.
|-
|Inflection
|A point at which the slope of a graph changes from an increasing slope (getting steeper) to a decreasing slope (getting less steep).
|-
|Uptalk
|A pattern of speech in which each sentence ends with rising inflection? like a question? A play on "uptick", and also on the second meaning of "inflection"
|-
|Bathtub
|possibly a reference to the so-called "{{w|Bathtub curve}}", also, the shape is similar to that of a bathtub, and is drawn containing water.
|-
|These two points define a line! Promising signal.
|In geometry, any two points define a line; also looks somewhat like a communication line between two towers. It is tempting when looking at market charts to draw imaginary lines that connect the extrema and hope it means something about the future. The drawn line in this case also just so happens to ignore the many periods of decline marked under "Declination" -- in this case it did eventually recover, but later labels (such as "likely to continue forever" at the end) suggest that this is more likely a case where blind optimism just so happens to have been right for those two particular points (as opposed to the many more possible pairs of points where the line wouldn't be so positive).
|-
|Yikes
|This section of the chart refers to the actual use of a candlestick chart, which is to document the difference between the opening and closing value of a stock. A long red bar shows that a stock closed at a much lower value than it opened at, which would be disastrous for someone trading that stock.
|-
|Wrong!
|The circled pair of bars are the only pair in the whole graph where two red bars (negative growth) that large are next to each other -- larger red bars exist, but not next to another one of similar magnitude. Labeling it "wrong" suggests the analyst is choosing to ignore reality by throwing out actual past data rather than revise the theory being held.
|-
|If I add some lines here I can convince myself I'm doing something more than just seeing patterns in the graph of a random walk
|A {{w|random walk}} is a mathematical object that describes a path that consists of a succession of random steps. Randall is trying to convince himself that the patterns in the stock chart are more meaningful than just random data. The {{w|Random walk hypothesis|random walk hypothesis}} is a financial theory that states that stock prices evolve according to a random walk, thus short-term price changes are random and cannot be predicted from past history.
|-
|Slope!
|The {{w|slope}} of a graph is the ratio of the "vertical change" to the "horizontal change". A measure of slope on a financial chart can be used to predict possible specific returns or losses, or to analyze those from the past, but Randall simply prints the word in his chart annotation, with an exclamation point possibly indicating how exciting its value is, rather than labeling the actual numeric slope. This could also be a play on a second meaning of slope, meaning a rising or falling surface in general.
|-
|Could be an omen
|This again makes reference to the financial meaning of the candlestick chart. The top of the small grey tick represents the highest value that the stock sold at over that day. The joke is that even though the stock did not grow appreciably, and actually sold at some point in the day for much lower, that it "could be an omen" that the value was rising.
|-
|Red + Green = Christmas
|Red and green are traditional colors for the {{w|Christmas}} holiday in the U.S.
|-
|Likely to continue forever
|This is a mistaken opinion often held by buyers in a rising market. It's been rising so much, surely it's the best time to buy! We could make millions! Such times are generally followed by a sharp downturn resulting in significant losses, as can be seen historically farther back on the chart. Cryptocurrency communities have significant members who call themselves "hodlers" -- these people always trust that the price will eventually go up even higher, because it has recovered so many times in the past.

The title text is a quote from {{w|James Tobin}} (from his 1984 paper [https://economicsociologydotorg.files.wordpress.com/2014/12/tobin-on-the-efficiency-of-the-financial-system.pdf ''On the efficiency of the financial system'']) that raises a question of very talented people building systems to make themselves a lot of money without actually accomplishing anything worth money. The quote was about the stock market and high speed traders in particular. It comments on the 'financialization' of the economy, where activities like speculation and abstracted financial products have become an increasingly large part of the economy, as opposed to investment in productive industry.

Interestingly, this comic appeared the day after [https://www.oxfamamerica.org/explore/stories/billionaire-wealth-grows-by-25-billion-a-day-while-poorest-wealth-falls/ Oxfam] reported that the world's 2,200 billionaires had added 12% to their wealth in 2018, while the 3.8 billion people comprising the poorest half of the world's population had lost 11%. Perhaps this prompted what appears to be Randall's jab at those whose business is merely making money.

2073: Kilogram

2018-11-17T13:32:02Z

162.158.126.40: Subjective comment removed.

{{comic
| number = 2073
| date = November 16, 2018
| title = Kilogram
| image = kilogram.png
| titletext = I'm glad to hear they're finally redefining the meter to be exactly three feet.
}}

==Explanation==
{{incomplete|Created by a CONSTANT PLANCK. Links to resources would be good. Do NOT delete this tag too soon.}}

On the day of this comic, the {{w|International Committee for Weights and Measures|International Committee for Weights and Measures}} voted to redefine the kilogram by fixing it to the value of Planck's Constant. This is done by passing a measured current through an electromagnet to exert a force to balance 1 kg. The change will take effect on May 20, 2019, when the platinum cylinder International Prototype Kilogram that defines the unit will be retired. This means that the mass of a kilogram will no longer be calibrated by comparing the relative mass of two physical objects, but by measuring the influence of an electromagnetic field relative to local gravitational forces.

The previous method of confirming that a kilogram is accurate is to use physical metal weights measuring exactly one kilogram, periodically transporting them around the world to an official weight lab to confirm they still weigh the same. Over time these physical objects have changed very slightly in their mass making them unreliable in the long run -- thus running into the issue that a kilogram did not stay a constant measure of mass. Note that these weights and comparisons are so precise that a fingerprint on one of the weights could throw them off.

In this comic, Black Hat announces that the kilogram has been redefined as equal to one pound. Ponytail and Cueball seem to think this makes things simpler, but Megan is rightfully alarmed. The metric system of measurement is the one used by most of the world and is the standard system used in science. It is considered superior to the {{w|United States Customary System}} and the {{w|Imperial system}} (both of which the pound is part of). Therefore, redefining the kilogram to be based on the pound would make things much, much worse and outrage supporters of the metric system. More to the point, the pound is still often defined by metal weights, thus running right back into the very same problem they tried to escape from.

In real life, the pound is officially defined as 0.45359237 kilograms, or less than half a kilogram. This makes defining a kilogram as one pound even more impossible as they are then stuck in a loop, as the pound must weigh less than half of a kilogram, meaning the value of each would be equal to zero.

In addition, the pound is a unit of weight, whereas the kilogram was a unit of mass, thus fixing the kilogram to the pound would make even less practical sense.

The title text continues the joke by saying that the meter has been defined as exactly three feet. The yard, the closest US measurement to the meter, is three feet. However, a meter is about 9 centimeters longer than a yard. As with the pound, the metric system is used to define the yard as it is officially defined as 0.9144 meters.

==Transcript==
:[Black Hat talking to Ponytail, Cueball, and Megan while all stand in a row. Megan's hands are raised emphatically.]
:Black Hat: To end many years of confusion, the International Committee for Weights and Measures has just voted to redefine the kilogram.
:Black Hat: As of next May, it will equal exactly one pound.
:Ponytail: Oh, cool.
:Cueball: That ''does'' make things simpler.
:Megan: '''''No!!'''''

==Trivia==
To further expand on this, the classic definitions of all our various units of time, length, mass, and temperature are based on phenomena that are neither convenient to measure precisely nor in fact consistently reproducible. The duration of an Earth day and year vary unpredictably, the circumference of the Earth varies, the International Prototype Kilogram gains or loses mass any time it is handled (and in fact just sitting there it and its reference copies diverge from each other), and the value of baseline temperatures such as the freezing point of water depend on which isotopes of hydrogen are in the water molecules.

Nevertheless, there really are constants of nature. For example, one of them is ‘''c''’, the speed of light in a vacuum. The expressed value of ''c'' depends on your choice of the unit of distance and the unit of time, but it’s a constant in those units. Now just suppose we all had a reproducible way to define a specific unit of time, which just for fun we call a ‘second’. You might not know the length of a ‘meter’, but if I told you that measured in meters per second the universal constant value of ''c'' is exactly 299792458 meters per second, then I would have fixed the length of a meter to be exactly the distance light travels in a vacuum in 1/299792458 seconds. And in fact this is what the international body responsible for defining our SI units has done.

One second is defined to be a specific number of certain state transitions of a cesium 133 atom. The specific number was set in the year 1965, so as to match a previous astronomical standard called Ephemeris Time to the limit of human measuring ability at the time. The 1965 definition didn’t change the actual duration of a second, but it did make its measurement forever reproducible.

In 1983 the value of ''c'' was fixed to the value noted above. Prior to that it had been measured with respect to existing definitions of a meter, and had to be expressed with a measure of uncertainty. For example in 1973 a team at the US National Bureau of Standards refined ''c'' to 299,792,457.4 m/s ± 1 m/s. But from 1983 onwards, with an exact integer value for ''c'' that is quite close to that Bureau measurement, the length of a meter is now fixed with no plus/minus uncertainty. Furthermore, both the second and the meter match their predecessor definitions for all intents and purposes.

Similar redefinitions of units of mass and of temperature in terms of universal constants have been agreed to, mass with regard to the Planck constant ''h'', and temperature with regard to the Boltzmann constant ''k''. The constants ''h'' and ''k'' had previously been measured quantities, complete with uncertainties. The SI body fixed both of them to exact values, resulting in exact, no-uncertainty values for a kilogram of mass and a kelvin of thermodynamic temperature. As with the second and the meter, these new definitions match their predecessor definitions for all intents and purposes.

To expand on this even further, three additional universal constants that were previously measured and that had uncertainty values have been assigned fixed values, resulting in exact definitions of three corresponding units of measurement without affecting their applicability. Fixing the unit of elementary charge, ''e'', serves to define the unit of electric current, the Ampere. Fixing the unit of luminous efficacy ''Kcd'' serves to define the unit of luminous intensity, the candela. And fixing the Avogadro constant ''NA'' serves to define the unit of amount of substance, the mole.

A very recent Wikipedia article about redefining the SI units of measure in terms of newly fixed values of things taken to be universal constants is {{w|Redefinition of SI base units}}.

1937: IATA Airport Abbreviations

2018-01-03T16:49:39Z

162.158.126.40:

}}

==Explanation==
{{incomplete|Expansion needed. Do NOT delete this tag too soon.}}
This comic is making fun of the three-letter codes assigned to all airports. These codes are overseen by the IATA (International Air Transport Association). Some airport codes are very intuitive, taking letters from the city name (e.g. DEN for Denver). Other codes are somewhat intuitive, taking a letter or two from the nearby city name but adding an additional letter (e.g. LAX for Los Angeles). Other codes make seemingly no sense at all (e.g. ORD for Chicago's O'Hare International, due to it formerly being named Orchard Field). In many cases, the airport codes appear to have been chosen (or invented) because they are also common abbreviations and acronyms.

1920: Emoji Sports

2017-11-26T03:24:00Z

162.158.126.40: /* Explanation */

{{comic
| number = 1920
| date = November 24, 2017
| title = Emoji Sports
| image = emoji_sports.png
| titletext = No horse has yet managed the elusive Quadruple Crown—winning the Kentucky Derby, the Preakness, the Belmont Stakes, and the Missouri Horse Hole.
}}

==Explanation==
{{incomplete|Still needs more explanation and a less humorous explanation of each sport concept - Please change this comment when editing this page. Do NOT delete this tag too soon.}}

This comic, as the heading indicates, arbitrarily selects emoji and uses them to make up very bizarre sports. Although some of these might be completely normal, most of them take things to a completely absurd level.

The title text is a reference to the triple crown, which is an highly prestigious award given to a three-year-old thoroughbred horse who wins the Kentucky Derby, the Preakness Stakes, and the Belmont Stakes, the first three of the four listed events. The joke is that were Horse Hole a real sport, then one who won a major competition for it, the Missouri Horse Hole, in addition to the three main horse racing events, they would then win a “Quadruple Crown".
{| class="wikitable"
!scope="col" style="width: 100px;" |Emoji

!scope="col" |Description
|-
|🤽‍♂️🌋
|Lavaball
|Sets the sport of water polo around or inside an active volcano. If the water is simply replaced with lava, the players would asphyxiate from the toxic fumes long before they burned to death in the molten rock. If a typical pool of water is involved, the introduction of lava would cause rapid evaporation and the release of {{w|Chlorine#Use_as_a_weapon|chlorine gas}}, which is destructive to living tissue. In any case, this game is not a good time.
|-
|🤾‍♀️🤺
|Bladeball
|Would also lead to the quick destruction of the ball - unless you are padding your weapons like in {{w|jugger}}.
|-
|💃💃⚽
|Fancyball
|It would be difficult to kick a giant football while wearing high heels (though possible with a normal sized one: https://www.youtube.com/watch?v=0GykP0XsLIA).
|-
|🕳️🏇🏇🏇
|Horse hole
|Horses might not cooperate or be serious injured when raced into a large hole. Not to be confused with horse golf, which is one way of describing polo. Both this segment and the title text may relate to Episode 354 of My Brother My Brother And Me, "Beanfreak", where a potential punishment for losing horses in a race is described as a trapdoor leading to a "pony pile" beneath the track. (Many of the podcast's episodes deal with horse racing and horse behavior, including some impassioned conversations on the performance of specific horses and the unregulated nature of the widely recognized Triple Crown achievement.)
|-
|🔪🏀⛏️
|Basketball Shredding
|Another sport which would be destructive on the equipment.
|-
|🥚🔭🕵️‍♀️
|Eggspotting
|This could be a combination of {{w|Egg_hunt|egg hunting}} and {{w|birdwatching}}; named like Trainspotting. A popular sport on Pinterest.
|-
|⛷️🐊
|Alligator Jumping
|Fast paced and popular spectator sport but limited season when both snow and alligators are readily available. This is actually a crocodile emoji. Not to be confused with "jumping the shark".
|-
|👩🎣🧜‍♂️
|Merfishing
|You probably won't catch a lot when fishing for {{w|Mermaid|mermaids}}.
|-
|👨🏸🧚🏸👩
|Tinkerball
|Playing badminton with a fairy, named after [[wikipedia:Tinker Bell|Tinker Bell]]. Probably hazardous to the Fae.
|-
|🥌🦔🥌
|Hedgehog Curling
|Hedgehogs are generally perfectly capable of curling without assistance (although they may get stuck on the ice).
|-
|🗜️🍔
|Burger Clamping
|What everyone wants to do after ordering the 3-layer burger, then wondering how to fit it into their mouths.
|-
|👩‍🚀🏹🛰️
|Consequence archery
|Archery on a space station would lead to the potentially explosive decompression of the space station, and necessitate the evacuation of the astronauts aboard.
|-
|🦉➡️📬
|Owlstuffing
|This appears to consist of attempting to stuff owls into mailboxes, which would be doubly illegal, because it would be cruel to the owls and interfere with delivery of the mail. The mailbox is shown with the flag up, which normally indicates that there is mail in it, but it appears to be empty, perhaps so that the owl can be stuffed in it. Possible reference to owls carrying mail in the Harry Potter series.
|-
|🍴🕯️🍴
|Candle Eating
|An even more unhealthy form of {{w|competitive eating}}. Eating large amounts of candle wax can cause {{w|Bowel_obstruction|intestinal obstruction}}.
|-
|⛳💣🏌️‍♀️
|Consequence Golf
|Rather than rewarding hole-in-ones, heavily punishes their absence. Also, would seriously damage the golf course.
|-
|👉🐍👈
|Snake Shaming
|Probably a play on snake charming. Also a possible reference to the biblical story where the snake is shamed for deceiving mankind by being doomed to crawl on its belly.
|-
|🔥🧗‍♀️🔥
|Hell Escape
|Trying to escape the {{w|lake of fire}} is the pastime of damned souls.
|-
