This comic gives a set of equations supposedly from different areas of science in mathematics, physics, and chemistry. To anyone not familiar with the field in question they look pretty similar to what you might find in research papers or on the relevant Wikipedia pages. To someone who knows even a little about the topic, they are clearly very wrong and only seem even worse the more you look at them. In many disciplines, the mathematical description of a large area is summed up in a small number of equations, such as Maxwell's equations for electromagnetism. In similar fashion, the equations here purport to encompass the whole of their given field.

===Simplified Explanations===

;All kinematics equations
Kinematics is the study of the motion of objects. More specifically, it describes how the location, velocity, and acceleration of an object vary over time. The equation shown contains two of these standard kinematic variables, velocity ''v'' and time ''t'', in addition to several quantities (''E'', ''K0'', and ''ρ'') that are completely unrelated to kinematics.

;All number theory equations
Number theory is a branch of mathematics concerned primarily with the study of integers. However, the equation shown contains the non-integer Euler's constant ''e'' (approximately 2.718). It also uses the Greek letter π as an integer-valued variable, even though the symbol π is used in mathematics almost exclusively to denote the well-known ''non''-integer circle constant (approximately 3.14159). Even with π treated as a variable here, one of its uses in the equation is still nonsensical. <math>\pi-\infty</math> uses ∞ as if it were a specific number, which it is not, thus giving an undefined result.

;All chemistry equations
Randall implies that all chemistry is just combustion of chemicals, demonstrated with an incorrect form of a common example chemistry equation of burning Methane and Oxygen (with added heat), to form water and carbon dioxide. However in this form "HEAT" is an actual molecule, rather than simply indicating the presence of heat to start the reaction. Thus the equation is modified to incorporate the fictional "HEAT" into the reaction. While the H in "HEAT" is the chemical symbol of the element hydrogen, none of the letters E, A, or T are symbols of any actual elements.

TODO: other simplified explanations.

===Technical Explanations===
;All kinematics equations
:<math>E = K_0t + \frac{1}{2}\rho vt^2</math>
{{w|Kinematics}} describes the motion of objects without considering mass or forces.

This equation here literally states: "Energy equals a constant <math>K_0</math> multiplied by time, plus half of density multiplied by speed multiplied by time squared".

The first term here is hard to interpret: it could be correct if <math>K_0</math> is a constant power applied to the system, but this symbol would more normally be used to denote an initial energy, in which case multiplying by <math>t</math> would be wrong. Alternatively, the term is similar to <math>k_B T</math> (sometimes written as ''kT''), a term that often appears in {{w|Statistical_mechanics|statistical mechanics}} equations, where ''kB'' (or ''k'') is {{w|Boltzmann_constant|the Boltzmann constant}}, and ''T'' is the {{w|Thermodynamic_temperature|absolute temperature}}. In this latter case, the term would have units of energy, consistent with the left side of the equation.

The second term looks similar to the kinetic energy term <math> \frac{1}{2}\rho v^2 </math> in [http://hyperphysics.phy-astr.gsu.edu/hbase/pber.html the Bernoulli equation] for fluids. (More properly, this is the kinetic energy ''density'' in the fluid).

The whole equation appears to be a play on the kinematics formula: <math>s = v_0t + \frac{1}{2}\ at^2</math>, where distance travelled (''s'') by a constantly accelerating object is determined by initial velocity (''v0''), time (''t''), and acceleration (''a'')

Kinematics is often one of the first topics covered in an introductory physics course, both at the high school and freshman college levels. As such, mixing in material from more advanced topics like statistical mechanics and the Bernoulli equation, even if done correctly, would be very confusing for a typical student learning kinematics.

;All number theory equations
:<math>K_n = \sum_{i=0}^{\infty}\sum_{\pi=0}^{\infty}(n-\pi)(i-e^{\pi-\infty})</math>
{{w|Number theory}} is a branch of mathematics primarily studying the properties of integers.

Said in English, the equation can be read: "The ''n''th K-number is equal to the sum for all ''i'' from 0 to infinity of the sum for all π from 0 to infinity of ''n'' minus π, multiplied by ''i'' minus ''e'' raised to the power of π minus infinity." (''i'' here is an iteration variable, not the imaginary number constant; ''e'' is Euler's number, approximately 2.718). A twofold misconception can be seen here. The first is the use of π as a variable instead of the circle constant (3.14...). This might be a jab at how in number theory letters and numbers are used interchangeably, but where some letters are suddenly fixed constants.

Further confusion comes from the use of unusual mathematical models. While the term <math>e^{\pi-\infty}</math> is meaningless when considered in standard ("high school") mathematics, it is valid when considered on the {{w|extended real number line}}, a concept unfamiliar to most non-mathematicians and uncommon in number theory. Naively, this would signify that (with the use of π as a variable) the exponent would range from negative infinity to zero. In fact, assuming ''e'' really does mean Euler's constant (or at least a real number strictly greater than 1) the term would be zero for every π < ∞. Ultimately, the sum diverges for every ''n''.

The close proximity of the letters i, e and π also evokes {{w|Euler's identity}} <math>e^{i\pi}+1=0</math> (also written <math>e^{i\pi}=-1</math>), without actually using it, especially since both π and i are used as variables here.

;All fluid dynamics equations
:<math>\frac{\partial}{\partial t}\nabla\cdot \rho = \frac{8}{23}
\int\!\!\!\!\!\!\!\!\!\;\;\bigcirc\!\!\!\!\!\!\!\!\!\;\;\int
\rho\,ds\,dt\cdot \rho\frac{\partial}{\partial\nabla}
</math>
{{w|Fluid dynamics}} describes the movement of non-solid material. In particular for gases, the density <math>\rho</math> is often the most interesting quantity (for liquids, this is often just constant). A unique feature of fluid-dynamic equations is the presence of {{w|Advection|advection terms}}, which take the form of often strange-looking spatial derivatives. This equation turns this up to a new level by differentiating with respect to a differential operator <math>\nabla</math>, which does not make any sense at all. Also it has a contour integral which seems reminiscent to a closed-circle process like in a piston engine, but this does not really fit in the context (differential description of a gas), and it has a pair of {{w|Magic number (programming)|unexplained numbers}} <math>8</math> and <math>23</math>, probably alluding to the {{w|Heat capacity ratio|specific heat ratio}} which is often written out as the fraction <math>\tfrac{7}{5}</math>, whereas most other physics equations [[899: Number Line|avoid including any plain numbers higher than 4]].

The title text stating that the electromagnetism equation is the same as the fluid dynamics equation, but with the arbitrary 8 and 23 replaced with the permittivity and permeability of free space is likely because electromagnetism equations often have relations to fluid dynamics, and because those two constants appear in the vast majority of electromagnetism equations.

;All quantum mechanics equations
:<math>|\psi_{x,y}\rangle = A(\psi) A(|x\rangle \otimes |y\rangle)</math>
{{w|Quantum mechanics}} is a fundamental theory in physics which describes nature at scales of atoms and below. It typically uses the {{w|Bra–ket notation|bra–ket notation}} in its formulae.

This equation takes a state psi in the dimensions of x and y and equates it to an operator A performed on psi multiplied by the same operator performed on the tensor product of x and y. Since the state psi is already the tensor product of the states x and y, this is equivalent to performing the same unknown operator twice on psi, and unless this operator is the identity or is its own inverse such as a bit-flip or Hermitian operator, this equation is therefore incorrect.

;All chemistry equations
:<math>\mathrm{CH}_4 + \mathrm{OH} + \mathrm{HEAT} \rightarrow \mathrm{H}_2\mathrm{O} + \mathrm{CH}_2 + \mathrm{H}_2 \mathrm{EAT}</math>
A {{w|Chemical equation|chemical equation}} represents a chemical reaction as a formula, with the reactant entities on the left-hand side, and the product entities on the right-hand side. The number of each element on the left side must match those on the right side. The energy produced or absorbed in this process is not included in that formula.

This is a modification of the combustion of methane. The correct form is often taught and a good example problem but obviously there are more chemistry problems.<math>\mathrm{HEAT}</math> is normally shorthand for {{w|activation energy}}, but in Randall's version it's jokingly used as a chemical ingredient and becomes <math>\mathrm{H}_2\mathrm{EAT}</math>, taking the hydrogen atom freed by the combustion equation shown. The proper methane combustion equation would be: <math>\mathrm{CH}_4 + 2 \mathrm{O}_2 \rightarrow 2 \mathrm{H}_2\mathrm{O} + \mathrm{CO}_2</math>

While <math>\mathrm{OH}</math> often appears in chemical equations in the form of a negatively charged hydroxide group (<math>\mathrm{OH}^-</math>), the left side of the equation involves a bare <math>\mathrm{OH}</math>, possibly the highly unstable hydroxyl radical (although this would typically be written with a leading dot, e.g. <math>\bullet\mathrm{OH}</math>). Similarly, the right side contains an unstable methylene radical which would generally only appear as an intermediate rather than a product.

;All quantum gravity equations
:<math>\mathrm{SU}(2)\mathrm{U}(1) \times \mathrm{SU}(\mathrm{U}(2))</math>
This is more similar to expressions which appear in {{w|Grand_Unified_Theory|Grand Unified Theory}} (GUT) than general quantum gravity. Unlike some of the other equations, this one has no interpretation which could make it mathematically correct. This is similar to the notations used to describe the symmetry group of a particular phenomena in terms of mathematical {{w|Lie_Group|Lie Groups}}. A real example would be the Standard Model of particle physics which has symmetry according to <math>\rm{SU(3)\times SU(2) \times U(1)}</math>. Here, <math>\rm{SU}</math> and <math>\rm{U}</math> denote the special unitary and unitary groups respectively with the numbers indicating the dimension of the group. Loosely, the three terms correspond to the symmetries of the strong force, weak force and electromagnetism although the exact correspondence is muddied by symmetry breaking and the Higgs mechanism.

Of course, an expression missing an "=" sign, is difficult to interpret as an "equation", because equations normally express an "equality" of some kind. Nobody knows whether Randal refers to a horse, zebra, donkey or other equine here.

Randall's version clearly involves some similar groups although without the <math>\times</math> symbol it is hard to work out what might be happening. A term like <math>\rm{SU(U(2))}</math> has no current interpretation in mathematics, if anyone thinks otherwise and possibly has a solution to the quantum gravity problem they should probably get in touch with someone about that.

;All gauge theory equations
:[[File:All gauge theory equations.png]]
In physics, a {{w|Gauge theory|gauge theory}} is a type of field theory which is invariant to local transformations. The term gauge refers to any specific mathematical formalism to regulate redundant degrees of freedom.

This equation looks broadly similar to the sorts of things which appear in gauge theory such as the equations which define {{w|Yang–Mills_theory#Quantization|Yang-Mills Theory}}. By the time physics has got this far in, people have normally run out of regular symbols making a lot of the equations look very daunting. The actual equations in this field rarely go far beyond the Greek alphabet though and no-one has yet to try putting hats on brackets. The appearance of many sub- and superscripts is normal (this links to the group theory origins of these equations) and for the layperson it can be impossible to determine which additions are labels on the symbols and which are indices for an {{w|Einstein_notation|Einstein Sum}}.

The left-hand side <math>S_g</math> is the symbol for some {{w|Action_(physics)|action}}, in Yang-Mills theory this is actually used for a so-called "ghost action". On the right-hand side we have a large number of terms, most of which are hard to interpret without knowing Randall's thought processes (this is why real research papers should all label their equations thoroughly). The <math>\frac{1}{2\bar{\varepsilon}}</math> looks like a constant of proportionality which often appears in gauge theories. The factor of <math>i = \sqrt{-1}</math> is not unusual as many of these equations use complex numbers. The <math>\eth</math> symbol looks similar to a <math>\partial</math> partial derivative symbol especially as the {{w|Dirac_equation#Covariant_form_and_relativistic_invariance|Dirac Equation}} uses a slashed version as a convenient shorthand.

The rest of the equation cannot be mathematically correct as the choice of indices used does not match that on the left-hand side (which has none). In particle physics subscripts (or superscripts) of greek letters (usually <math>\mu</math> or <math>\nu</math>) indicate terms which transform nicely under Lorentz transformations (special relativity). Roman indices from the beginning of the alphabet relate to various gauge transformation propetries, the triple index seen on <math>p^{abc}_v</math> would likely come from some <math>\rm{SU(3)}</math> transformation (related to the strong nuclear force). Since <math>S_g</math> has none of these (and is thus a scalar which remains constant under these operations), we would need the right-hand side to behave in the same way. Most of the indices which appear are unpaired and so will not result in a scalar making the equation very wrong. For those not familiar with this type of equation, this is similar to the mistake of messing up units, for instance setting a distance equal to a mass.

;All cosmology equations
:<math>H(t) + \Omega + G \cdot \Lambda \, \dots \begin{cases} \dots > 0 & \text{(Hubble model)} \\ \dots = 0 & \text{(Flat sphere model)} \\ \dots < 0 & \text{(Bright dark matter model)} \end{cases}
</math>
This is a parody of equations defining the {{w|Hubble's_law#Derivation_of_the_Hubble_parameter|Hubble Parameter}} <math>H(t)</math> although it looks like Randall has become bored and not bothered to finish his equation. Such equations usually have several <math>\Omega</math> terms representing the contributions of different substances to the energy-density of the Universe (matter, radiation, dark energy etc.). In this context <math>G</math> could be Newton's constant and <math>\Lambda</math> is the cosmological constant (energy density of empty space) although seeing them appear multiplied and on the same footing as <math>H</math> is unusual (the dot is entirely unnecessary). Choosing to make <math>H</math> a function of time <math>t</math> and not of redshift <math>z</math> is also unusual.

The second section looks like the inequalities used to show how the equation varies with the shape of the Universe, based on the value of the curvature parameter <math>\Omega_k</math>. A value of 0 indicates a flat Universe (this is more or less what we observe) while a positive /negative value indicates an open /closed curved Universe. Randall's choice of labels further makes fun of the field as both a flat sphere and bright dark matter are oxymoronic terms which would involve some rather strange model universes.

;All truly deep physics equations
:[[File:All truly deep physics equations.png]]
<math>\hat H</math> is the Hamiltonian operator, which when applied to a system returns the total energy. In this context, U would usually be the potential energy. However, there is also a subscript 0 and a diacritic marking indicating some other variable. Much of physics is based on Lagrangian and Hamiltonian mechanics. The Lagrangian is defined as <math>\hat L = \hat K - \hat U </math> with K being the kinetic energy and U the potential. Hamiltonian mechanics uses the equation <math>\hat H = \hat K + \hat U </math>. The Hamiltonian must be conserved so taking the time derivative and setting it equal to zero is a powerful tool. The "principle of least action" allows most modern physics to be derived by setting the time derivative of the Lagrangian to zero.

I figured out indirect (diffused) lighting in 1982, in McCutcheon Hall at Purdue University. The central hall had lots of light, but no observable, central light source. I discovered that the light came from hidden fluorescent tubes, diffused against a plastered ceiling. The light we saw, came from overhead, in every direction. The basic outcome is: the more quanta you have, the less precise your measurement can be. OTOH, fewer quanta cast a sharper shadow.

The frosted bulb diffuses the shadows of the filament. The bulb's reflector can be an offset to the diffusion.

it may be worth noting that unlike the name impl9es (or as imagined by the Star Trek TNG episode), it is unlikely that a Dyson Sphere would actually be a spherical shell due to gravitational forces that would be exerted on such a structure.

OMG, iPhone 8 and iPhone X were released at the same time. There is no current phone existing which follows iPhone 8 and there may be a iPhone 9 in the future. The X is pronounced ''ten'' but that phone is not the successor of the iPhone 8. Until now Microsoft is the one company who omitted the version number 9.

:I know almost nothing about most sports, and less about basketball (at least the sports fan end of it), and with this explanation I feel certain it's "beginning". Somewhat pointless at the end, when all is over and settled. They would make such brackets to either predict how the Sweet 16 will fill out, or to record how it DID fill out. With the mouse-over contribution, these are clearly predictions. I wonder if Randall hedged between saying "at the beginning of the season" and "early in the season", since the Sweet 16 seems to come about once the season is well underway, so then "early" would be more accurate, then he forgot to pick one... - NiceGuy1 [[Special:Contributions/108.162.219.88|108.162.219.88]] 04:28, 7 April 2017 (UTC)

520: Cuttlefish

2017-04-04T14:09:19Z

108.162.219.88: /* Transcript */

{{comic
| number = 520
| date = December 22, 2008
| title = Cuttlefish
| image = cuttlefish.png
| titletext = Unless the CS students finish the robot revolution before you finish the cephalopod one.
}}

==Explanation==
It appears that [[Cueball]] and [[Megan]] are {{w|physicists}} visiting a biology lab. Their guide, a {{w|biologist}} looking like Cueball, gives them a description of the humble {{w|cuttlefish}} that is both accurate and makes them sound like other-worldly creatures with highly advanced capabilities.

The scene takes an unusual turn when the scientist implies that the cuttlefish have been easily trained to improve their capabilities. He then demonstrates this by giving a simple command, whereupon the cuttlefish rises out of the water only to attack and kill both Cueball and Megan, demonstrating an ability to fly, talk and discharge lethal electric shocks in the process. (See also [[35: Sheep]]).

This is all revealed to be a dream, but it has given Cueball a warning not to underestimate the biologists. Apparently, they can be just as crazy and dangerous as any other kind of scientist. Cueball (that represent [[Randall]] as it is xkcd that salutes in the final panel) offers a toast to all biologists everywhere and plans an alliance with them against the {{w|chemists}}, hoping to prevent further attacks on physicists. He is then shown drinking from a laboratory flask, something which any scientist would be wary of.

In the past, Randall has been somewhat dismissive of the non-math/non-physics scientific disciplines, so this comic may be trying to mend some bridges with biologists. But not with chemists.

In the title text, CS stands for {{w|Computer Science}}. The "robot revolution" references events in film and literature, wherein robots, having become commonplace in the workforce, achieve independent thought and declare war on humanity, like in {{w|The Terminator}}, {{w|The Matrix}}, or the movie {{w|I, Robot}}. Randall implies that the physicists will switch sides if the robot revolution arrives first. {{w|Cephalopod}} is the class of animals that encompasses cuttlefish as well as {{w|squids}} and {{w|octopuses}}.

==Transcript==
:[A scientist (looking like Cueball) is pointing into an aquarium tank with two small animals floating in the water. He explains that they are cuttlefish to Cueball and Megan who are on the other side of the tank looking into it, Cueball with a hand to his mouth. Above them there is a frame inside the panel with a caption:]
:We visit a bio lab:
:Scientist: These are cuttlefish.

:[Very detailed drawing of a cuttlefish, with it's special W shaped pupils, all eight arms and two longer tentacles, and the striped body with waving parts shown waving down each side. The scientist tells about the animal with text above and below.]
:Scientist (off-panel): They're frighteningly smart, have manipulating arms and tentacles, have ink jets, can dart backwards and see the polarization of light through their w-shaped pupils.
:Scientist (off-panel): And their sides are 200 dpi display screens which they use for camouflage and communication.

:[Back to the original setting where the scientist stand a little further back from the tank with his arms down. Cueball and Megan has also moved further back and are even leaning away from the tank]
:Scientist: When we realized how intelligent they were, we began to teach them.
:Scientist: They've advanced quickly.
:Scientist: '''Cuttlefish: GO.'''

:[The two cuttlefish float straight out of the tank (lines indicating they movement water splashing at the surface of the tank). The scientist looks down at them, while Cueball and Megan holding hands and leans further back and Cueball takes his hand back to his mouth.]

:[Pan to only the scientist, standing with one arm bend in front of him and the other holding a finger up to his mouth, and the tank from where the cuttlefish now flies towards Cueball and Megan who are now off-panel. Lines behind the cuttlefish shows they fly right but bobbing up and down. The cuttlefish talks in a strange way where the letters are alternately up and down.]
:Cuttlefish: K<big>I</big>L<big>L</big> T<big>H</big>E P<big>H</big>Y<big>S</big>I<big>C</big>I<big>S</big>T<big>S</big>
:Cuttlefish: K<big>I</big>L<big>L</big> T<big>H</big>E P<big>H</big>Y<big>S</big>I<big>C</big>I<big>S</big>T<big>S</big>

:[Pan to Megan and Cueball, with the tank almost inside the left frame. Both cuttlefish is surrounded by their own zigzag line, which then extends from them in a thin line to encompass either Cueball or Megan. Cueball was running away from them, when this happens, legs bend at the knees and arms out and one bend. Megan has fallen lying face down arms out.]

:[In this panel with faint gray shading Cueball is waking up in bed from the dream rising up to sitting position suddenly as indicated with two movement lines behind his head. One arm is supporting him on the bed next to the pillow, and the other is pulling his sheet down away from his torso. The first sentence is maybe still part of the dream as there is no line from Cueball to the sentence, and it is written high up. There is a line to the second sentence.]
:Cueball: Oh god.
:Cueball: I knew it.

:[This panel is divided into five segments. At the top there is a large caption in two lines. The there are three drawings following each other from left to right. First a bottle is pouring liquid into a an Erlenmeyer flask (a conical laboratory flask) which is half full. Then Cueball takes the flask and holds it up as a salute. Finally he drinks from it leaning his head way back. Below there is more text.]
:<big>xkcd</big>
:Salutes Bio Majors
:If we join you against the chemists, will you train your fleshy minions to leave us alive?

1804: Video Content

2017-03-03T14:10:09Z

108.162.219.88:

{{comic
| number = 1804
| date = February 27, 2017
| title = Video Content
| image = video_content.png
| titletext = "So, like, sexy news videos?" "No, people have tried that--it's still just video content. We need to actually inform people THROUGH making out. I would call it 'Mouth Content,' but I think that's already the title of a Neil Cicierega album."
}}

==Explanation==

This comic is a commentary on the declining {{w|publishing industry}} and their unsuccessful attempts at regaining an audience.

News media has evolved dramatically as the world entered the {{w|information era}}. {{w|Newspapers}}, which were at one point the most widely distributed and consumed form of media, have rapidly been eclipsed by new technologies such as {{w|television}}, {{w|Internet}}, and {{w|streaming video}}. Subscriptions to paper-based media have been drastically declining to the point where many {{w|publishers}} are on the verge of shutting down. While publishers are making an effort to move their content to newer, more popular forms of media, in many cases they are still clearly behind the times.

The comic illustrates one such example with [[Cueball]] suggesting presenting news stories as videos rather than text. This is presented and received by [[Megan]], [[Hairbun]] and [[Hairy]] as a clever new idea that would appeal to young people based on the fact that they like watching {{w|YouTube}} videos. However, apparently no one in the comic has realized that television news programs have been filling such a niche for decades and that young people are just as disinterested. In fact, online video based news is often considered annoying, especially if autoplaying or if there is no text based alternative. In reality, this idea is not at all original and likely to be doomed to fail from the start. As with many similar attempts, the new "ideas" that publishers are trying to adopt are merely cramming news content into things young people like, without really understanding why they like it and without considering whether news would be a good fit.

In the caption, [[Randall]] suggests it would be pointless to argue with newspaper publishers about their ideas. Presumably Randall believes publishers who fall for those ideas are already out of touch with the new generation, and would not be able to understand why those ideas lack merit. Instead, he suggests taking the trend to a ridiculous extreme, by telling publishers that young people like {{w|making out}}. Suppose publishers follow the same pattern and try to cram news into this as well, they would end up creating some form of news program centered around making out. The results may turn out completely laughable or highly entertaining. If the former, it could serve as a wake-up call to publishers that they need to reconsider their approach. If the latter, then it could actually become a trend and unexpectedly reinvigorate the industry.

In the title text it seems like the news agency actually consider this idea, or is at least confused enough to ask. Their interpretation of combining "making out" with news is to make it sexy, but the next speaker says that this has been tried before and doesn't work. This is likely a reference to {{w|Naked News}} {{NSFW}}, a news program that does that: it features attractive women delivering the news while simultaneously disrobing. This concept has not, for some reason, spread to the mainstream.

According to the speaker, merely making the news sexy is not enough – the news content must be ''directly'' integrated into the making out; how this would be accomplished is as yet unclear.

The title text also dismisses the proposed name ''Mouth Content'' as possibly the title of a {{w|Neil Cicierega}} album, in reference to his recently-released {{w|Mouth Moods}}, as well as his prior albums {{w|Mouth Sounds}} and {{w|Mouth Silence}}.

==Transcript==
:[From left to right: Hairy, Cueball, Megan and Hairbun sit around a conference table.]

:Megan: Good idea!

:Instead of arguing with newspapers about this, we should just tell them how much young people like making out and see what happens.

108.162.219.88: /* Explanation */

{{comic
| number = 1802
| date = February 22, 2017
| title = Phone
| image = phone.png
| titletext = [*disables social networking accounts*] [*social isolation increases*] Wait, why does this ALSO feel bad?
}}

==Explanation==
{{incomplete|Feel free to add more info. Also, what's the real punchline?}}
Someone asks [[Cueball]] if he wants to go for a walk. He says sure, but first he has to get his phone. The joke is that he describes this as a device that gives him a 24/7 stream of information, much of which is out of context. He also mentions that news can be scary, which is true and often times news outlets will use a title that exaggerates the topic and creates fear to get more people to look at the article. The random emotional stimuli could be from many things such as his text messages or email and several other things that can cause a shift in emotions. The spare battery could reference a portable charger as most phones use rechargeable batteries that can last longer than the rest of the phone.

The title text implies that even after disconnecting from social networks, which Cueball may think causes his isolation by severing him from the real world, which Cueball thinks will solve the problem, he still feels as isolated as he was before. Presumably, he disconnected to solve his problem and be able to focus on his walk, however, he ends up feeling bad the whole walk.

[[Randall]] often describes simple object in a very complex or connotative manner such as in [[1616]]. (Note: He also occasionally describes very complex things in very simple words as in [[1133]] or in his book [https://store.xkcd.com/pages/thing-explainer-book Thing Explainer])

This comic could be seen as a counter to [[1773: Negativity]], as both deal with the inability to escape the media during objectively peaceful pastimes. While in the former, the nature attacks Cueball with the types of comics he wishes to avoid, here, he brings along his phone even though it will ruin the goal of the walk he is going to take.

==Transcript==
:[Someone offscreen talks to Cueball who walks to a small table with some items on it.]
:Offscreen: Wanna go for a walk?
:Cueball: Sure, just need to grab my device that feeds me a 24/7 stream of opinions, context-free scary world news, and random emotional stimuli.
:Cueball: Plus a spare battery so the feed won't be interrupted.

==Explanation==
[[White Hat]] tries to start a conversation with [[Cueball]] about the [[wikipedia:Star Wars|''Star Wars'']] sci-fi film franchise, which Cueball cuts short by stating that he has never seen the movies. This deeply astonishes White Hat. Because the movies are known worldwide and are ingrained into American pop culture, White Hat considers seeing ''Star Wars'' a universal experience.

Cueball reasons that not having watched the films is the "default option". In other words, humans are not born with intrinsic knowledge of the series. In fact, ''Star Wars'' was started very recently on the scale of human existence, so the majority of people ever to exist were never able to watch it{{Citation needed}}. As for why he has not watched ''Star Wars'' despite being fully able to do so, Cueball goes on to say that ''not'' doing most given things is easy, appealing to his own apparent laziness. Another possible reason is that, while it is hard to find information about how many have seen Star Wars (especially given home video releases), one estimate is about 1000 million people have seen at least one of the Star Wars movies. This amounts to 10% of the current world population, so 9/10 will not have seen it. In the US and the rest of the Western world, the fraction of people having seen at least one of the movies may be above 50%, which makes Cueballs factoid incorrect from a statistical point of view, even if he is still right about "not doing something" being the default option.

Another word play here is that "default" means "failure to do something required by duty or law : neglect" according to dictionaries, so it is _literally_ the default option.

When White Hat finally begins to grasp that Cueball has indeed not seen ''Star Wars'', he declares that they must see it very soon or even immediately. When Cueball's response is one of uninterest again, White Hat seemingly calls in social reinforcements to agree with him that watching ''Star Wars'' is the norm. Cueball feels threatened by his friend's unreasonable behavior and quickly removes himself from the situation.

Later, [[Ponytail]] likewise wishes to start a conversation about ''Star Wars'', this time about a new movie coming out. Based on his previous experience, Cueball reconsiders admitting to not having seen the past movies, and instead pretends to be looking forward to the new one. Ponytail then tries to continue the conversation, so Cueball bluffs with an incorrect declaration that Darth Vader eats Jedi, likely constructed from other mentions of the ''Star Wars'' characters that he has overheard throughout his life. Cueball carefully chooses his words to make it seem as if he knows what he is talking about.

However, Ponytail doesn't call him out on this error, instead agreeing with it. Cueball is relieved—expressed as his thinking an onomatopoetic sigh of relief—as he believes he has guessed at an accurate piece of information and has avoided entering a similar situation to the previous one. The punchline of this part of the comic is Ponytail's identical feeling of relief, showing that she likewise hasn't seen ''Star Wars'', is also hiding this fact, and is also glad to not be caught. It may be inferred that Ponytail thinks not starting a conversation about ''Star Wars'' might expose her as someone who doesn't follow the series closely.

The title text is a tip for people like Cueball, to help them hide deception when roped into conversations about the films. It argues that since the ''Jedi Prince'' series of novels established so many strange concepts that don't mesh with most other canon information, it makes for an excellent scapegoat to blame ill-fitting declarations on, seeing as even the most devoted, well informed fan has agreed to forget the entire series. Casually bringing up such a forgotten series might also make the bluffer out to be extremely knowledgeable about the ''Star Wars'' franchise as a whole.

This comic is most likely in reference to a then-new ''Star Wars'' movie, ''Rogue One'', which will release into American theaters 9 days after the publishing of the strip on December 16, 2016 (exactly a week before the Belgian release of December 14), or ''The Force Awakens'', which had been out for a while at the time.

The huge pop cultural success of Star Wars means it is genuinely surprising to encounter an individual who has not seen it (at least amongst the typical audience of XKCD). The TV series "How I Met Your Mother" had an episode based around this premise, and there is a radio comedy chat show on [[wikipedia:BBC Radio 4|BBC Radio 4]] in the UK titled [[wikipedia:I've Never Seen Star Wars (radio series)|I've Never Seen Star Wars]], in which celebrity guests try out experiences that are common to others, but new to them, as well as a television version.

[White Hat and Cueball are still facing each other]
:White Hat: We ''have'' to watch it!
:Cueball: Nah, I'm good.

[White Hat has turned away from Cueball and has his hands to his mouth to shout to people off-panel. Cueball has likewise turned away as he walks away and is speaking back over his shoulder]
:White Hat: ''Hey everyone! This guy's never seen Star Wars!''
:Cueball: Listen, I gotta go.

:Cueball: …Yeah! Excited for it! Big fan.

[Ponytail holds her phone to her side, transferred to her right hand, as she and Cueball face each other]
:Ponytail: What'd you think of the last one?
:Cueball: Uh… That Darth Vader, man.
:Cueball: Sure does love eating Jedi.

[Ponytail and Cueball continue facing each other]

45: Schrodinger

2015-08-27T13:41:33Z

108.162.219.88: removed incomplete tag complaining that explanation was too long

{{comic
| number = 45
| date = January 4, 2006
| title = Schrodinger
| image = schrodinger.jpg
| titletext = There was no alt-text until you moused over
}}

==Explanation==
This comic is a joke creating a humorously false synthesis, combining the principals of quantum superposition and the effects of reading a comic one panel at a time.

{{w|Schrödinger's cat}} is a thought experiment that illuminates the notion that a particle only resolves itself to its state upon observation, and until this observation it is in all of its possible states simultaneously. In the thought experiment a cat is both dead and alive until observation, likewise in this comic the comic is both funny and unfunny until the comic is observed (or read).

[[Black Hat]] and [[Cueball]] are likening the last panel to the box with the cat: until you read it, it is in a mixed state (a superposition) of both funny and unfunny. In the last panel Black Hat says "Shit."

The joke is that after reading the last panel the comic is both funny (as it is unexpected) and not funny (as the last line was a non sequitur and therefore there is no climax) at the same time, thus proving Black Hat and Cueball wrong, hence them expressing discontent with the word shit.

The [[Title text|title text]], which Randall here calls the alt-text, suggests that the alt text did not exist until the mouse over action occured.

===Schrödinger's cat===
Schrödinger's cat is a famous thought experiment proposed by {{w|Erwin Schrödinger}} to question the {{w|Copenhagen interpretation}} of quantum mechanics.

Under the {{w|Copenhagen interpretation}}, any particle is described by a {{w|wave function}} that allows one to calculate the probability that it is any given state. A radioactive nucleus with a half-life of one hour, for instance, would have a wave-function that would split, showing two distinct states (decayed, undecayed) that change over time until some "observation" forced the wave-function into one state or another (called "collapsing the wave-function"). Before the wave-function is collapsed, it is incorrect to say that the atom has decayed or has not decayed; it is in a "superposition" of states, effectively half-decayed and half-undecayed.

Schrödinger thought the Copenhagen interpretation was absurd, and devised the below thought experiment to show this. The experiment goes as follows: Put a cat in a box, he said, with a device triggered by the decay of an atom with a half-life of one hour that would release a poisonous gas if triggered. Then, after waiting an hour, the Copenhagen interpretation would say that the atom is in a superposition of decayed and undecayed states, and thus, by extension, the cat would be in a superposition of alive and dead states. Only when the box is opened would the wave-function for the cat collapse into either alive or dead states. This thought experiment is not meant to be taken literally as every interaction of a particle with another constitutes a observation, and many particles must interact for a cat to die, but still his argument was that since it is absurd for a cat to be both alive and dead, it is absurd for an atom to be both decayed and undecayed.

If this experiment were to be performed the cat would not be both dead and alive.

==Trivia==
*This was the 42nd comic originally posted to [[LiveJournal]].
**The previous was [[39: Bowl]].
**The next was [[46: Secrets]].
*There had been a break of almost a month between this and the previous comic.
**This time was probably used to prepare the launch of the new [[xkcd]] site.
*Original title: "Drawing: Schrodinger"
**For the first time in eight comics, and only the second time since after the first day on LiveJournal, is the weekday not part of the title on LiveJournal.
**But apart from in the very next comic, the extra word "Drawing" was still added to the title for this and the four comics after the next, in spite of the simultaneous release on xkcd.
*There were no original [[Randall]] quote for this comic.
*This was the first comic to be posted simultaneous (i.e. on the same day) on both LiveJournal and the new xkcd site.
*This comic was thus one of the last 11 comics posted on LiveJournal.
**These 11 comics were [[:Category:Posted on LiveJournal after xkcd|posted both on LiveJournal and xkcd]] after the xkcd site opened on the 1st of January 2006.
**They were not all posted on the same day though.
*The {{w|Schrödinger equation}} was enhanced by {{w|Paul Dirac}} only three years later in 1928: {{w|Dirac equation}}. It did combine the Schrödinger world with Einstein, e.g. relativity.
*Black Hat's hat is beginning to shorten from its top-hat look, although its height varies between panels. (As does Cueballs height compared to Black Hat.)

1541: Voice

2015-06-22T16:00:44Z

108.162.219.88: /* Explanation */

{{comic
| number = 1541
| date = June 22, 2015
| title = Voice
| image = voice.png
| titletext = Anyway, we should totally go watch a video story or put some food in our normal mouths!
}}

==Explanation==
{{incomplete|First draft; Alt-Text explanation missing}}

During a casual talk, [[Ponytail]] suddenly interrupts her normal speech stating that she is for some reason only capable of controlling her own voice once every six years, apparently for a very brief time since she immediately returns to the casual talk, continuing her previous sentence mid-word before being able to tell Megan how she could help her. Upon Megan's confused request, she denies knowledge of the occurrence, although in a somewhat suspicious way, using a possibly fake laughter.

It remains unclear if this is just a prank by Ponytail, or if she is indeed possessed by some sort of power that prevents her from expressing her own thoughts, except for a very short time every six years. If the latter is the case, it appears that Ponytail's usual "self" is indeed said power and is aware of suppressing the "real" Ponytail, as becomes clear by her response to Megan's inquiry.

The title text suggests that Ponytail is possessed by some sort of inhuman entity, most likely an alien or AI (possibly a Yeerk from, the Megamorphs series), unfamiliar with movies and eating. A similar situation was recently explored in [[1530: Keyboard Mash]].

==Transcript==
