203: Hallucinations

{{comic
| number = 203
| date = December 29, 2006
| title = Hallucinations
| image = hallucinations.png
| titletext = And the possibility of lucid dreaming just makes it that much more fascinating.
}}

==Explanation==
[[Cueball]] on the right is talking to his (Cueball-like) friend about {{w|dream|dreaming}} but using words and phrases to make dreaming sound much more dramatic than we usually think that it is. However, the description is technically correct.

[[Randall]] is using the comic to make a point about how we think dreaming is so normal, but if we actually realize what's happening, dreaming is very strange:
*go comatose for a few hours = sleep for a few hours
*hallucinate vividly = dream
*suffer amnesia about the whole experience = forget the dream
The character on the left takes this as though the experience is normal. Which it indeed is, but that is why Randall has the caption above the guys: ''Sometimes it seems bizarre to me that we take dreaming in stride.''

The title text is about {{w|Lucid dream|lucid dreaming}}, where the dreamer is aware that they are dreaming. This is even more fascinating to Randall. He uses this type of dream in [[269: TCMP]].

==Transcript==
:[Two Cueball-like guys are talking. Above them is the following caption:]
:Sometimes it seems bizarre to me that we take dreaming in stride.

:Friend: Are you coming to dinner?
:Cueball: Yeah, but first I'm gonna go comatose for a few hours, hallucinate vividly, and then maybe suffer amnesia about the whole experience.
:Friend: Okay, cool.

2191: Conference Question

2019-08-20T20:28:00Z

172.69.70.131: match punctuation formatting to neighboring word

{{comic
| number = 2191
| date = August 19, 2019
| title = Conference Question
| image = conference_question.png
| titletext = I also have an utterance. Less of an utterance and more of an incantation. Less of an incantation and more of a malediction. Less of a malediction and more of a Word of Power. Less of a Word of Power and more of an Unforgivable Curse.
}}

==Explanation==
{{incomplete|Created by a BOT that's more of a FRIENDLY BUG. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

Usually at a conference or other event involving a speaker addressing a crowd, members of the crowd are given the chance to ask questions. This is intended so that people can perhaps ask the speaker to elaborate on a point they've made, or to ask the speaker's opinion on a topic related to their talk.

Occasionally, people at such an event will use (or, rather, abuse) the opportunity to ask a question to instead provide their own (unsolicited) opinion or statement. Such statements are often preceded with something along the lines of "I have a question. Well, less of a question and more of a comment." This formulation in particular has attracted a lot of criticism, eg. [https://jamesmendezhodes.com/blog/2019/4/30/less-of-a-question-more-of-a-comment], for not adding anything to the discussion and for pulling focus away from the speaker.

In the comic, this idea is taken to an extreme, with [[Beret Guy]] not only transforming the opportunity to ask a question into an opportunity to make a statement, but through successive transformations, turning this into an opportunity to show off a bug he has found.

:'''Question.''' A {{w|question}} is what the crowd member is expected to provide, such that the speaker or a panel member could provide a related answer.

:'''Comment.''' A {{w|Topic and comment|comment}} by a crowd member, is when they just say something they believe, without expecting an answer, giving the speaker or panel members nothing to do. This may be seen as annoying by everyone else, as the crowd did not come to hear the opinion of other crowd members. But answers to relevant questions would be interesting to the crowd and the panel.

:'''Utterance.''' An {{w|utterance}} is just making a noise, which may or may not be actual words, or if actual words it may not be a complete sentence.

:'''Air Pressure Wave.''' {{w|Sounds}} are literally pressure waves in the air. So this could be a simple sound, or not a sound at all depending on the severity of the wave. It might be the person simply blowing.

:'''Friendly Hand Wave.''' Now instead of using his mouth to generate an air pressure wave, he's producing it with his hand, in a manner intended to be interpreted as "friendly". Many times hand waves are done in a friendly manner, designed more for the visual appeal than the amount of air pressure waves they generate.

:'''Friendly Bug.''' Now he is no longer doing anything himself, except to point out the fact that he has found a bug or {{w|insect}}, which he {{w|anthropomorphizes}} as being friendly.

:'''Want to meet it?''' He has decided that he and the friendly bug are actual friends, and ironically comes full circle by finally asking a question, though presumably whether the speaker wants to meet a bug is not related to the topic of the speaker's talk.

The title text takes the opposite route of Beret Guy, and each step instead refers to successively worse forms of magic spells which would, presumably, have a negative effect upon the listener. Starting from a mere utterance and then using Beret Guy's "it is less than" scheme, it progresses over worse and worse curses, ending with an unforgivable curse!

:'''Utterance.''' It begins with utterance which was also used by Beret Guy. See above.

:'''Incantation.''' {{w|Incantation}}, or a spell, is a magical formula intended to trigger a magical effect on a person or objects. It is not necessarily with evil intent.

:'''Malediction.''' A malediction is another word for {{w|curse}} (the prefix "mal" being a Latin root meaning "evil"). This is always with evil intent.

:'''Word of Power.''' "Word of Power" could refer to the dragonish form of magic in ''{{w|The Elder Scrolls V: Skyrim}},'' or the [https://dungeonsdragons.fandom.com/wiki/Power_word early 1st edition Dungeons & Dragons high level spells].

:'''Unforgivable Curse.''' The term "{{w|Magic_in_Harry_Potter#Unforgivable_Curses|Unforgivable Curse}}" refers to a set of three spells from the {{w|Harry Potter}} series, said to be so evil that their use on another person is unforgivable and illegal. The three spells are able to mind control (''Imperius''), torture (''Cruciatus''), and kill (''Avada Kedavra'') their target.

The title text can be interpreted as a reply by [[Hairy]] (the speaker) to Beret Guy, indicating his annoyance at the topic being derailed. It could also be representative of [[Randall|Randall's]] feelings towards those who abuse the opportunity to ask a question in order to make a statement. Randall has recently done some book tours and was at {{w|San Diego Comic-Con}} [https://blog.xkcd.com/2019/07/15/san-diego-comic-con/ last month] where he served on various panels, so he probably has had personal first-hand experience with these kinds of circuitous non-questions.

==Transcript==

:Beret Guy: I have a question.
:Beret Guy: Well, less of a question and more of a comment.
:Beret Guy: I guess it's less of a comment and more of an utterance.
:Beret Guy: Really it's less an utterance more an air pressure wave.
:Beret Guy: It's less an air pressure wave and more a friendly hand wave.
:Beret Guy: I guess it's less a friendly wave than it is a friendly bug.
:Beret Guy: I found this bug and now we're friends. Do you want to meet it?

2125: Luna 2

2019-03-19T01:14:33Z

172.69.70.131: /* Transcript */ corrected typo in shrapnel

{{comic
| number = 2125
| date = March 18, 2019
| title = Luna 2
| image = luna_2.png
| titletext = The flags were probably vaporized on impact, because we launched it before we had finished figuring out how to land. That makes sense from an engineering standpoint, but also feels like a metaphor.
}}

==Explanation==
{{incomplete|Created by a FLAGMENTATION GRENADE. Title text needs to be explained, . Do NOT delete this tag too soon.}}

This comic is referring to {{w|Luna 2}}, the first man-made object to make contact with the surface of the moon, and consequently, as stated in the comic, the first man-made object to touch another world. On September 13, 1959, it hit the Moon's surface east of {{w|Mare Imbrium}} near the craters Aristides, {{w|Archimedes}}, and {{w|Autolycus}}.

[[Megan]] is sitting in front of a computer, and telling [[Cueball]] about the Luna 2. She explains that the probe was designed to explode on impact, thus scattering multiple metal Soviet flags and ribbons on the surface of the Moon. They compare it to throwing a shrapnel grenade with flags in it at the moon.

Cueball's observation that it is "on-brand" for humans to litter another world with an explosion of nationalist iconography immediately upon reaching it, is a reference to the vastly numerous historical instances when, upon setting foot on territory for the first time, humans "conquer" it, by planting flags on the first thing they see.

==Transcript==
:[Cueball is standing behind while Megan sits at a laptop.]
:Megan: Huh. ''Luna 2'', the first artificial object to touch another world, carried a sphere made of steel Soviet flag emblems.

:[A patterned sphere is shown blowing up to pieces.]
:It was designed to blow apart on impact, scattering tiny metal flags and ribbons across the surface of the moon.

:[Close-up of Cueball and Megan's faces.]
:Cueball: So the first physical contact humans had with a heavenly body...
:Megan: ...was throwing a shrapnel grenade full of flags at it.
:Cueball: Well, it's on-brand for us, at least.

2034: Equations

2019-01-21T07:26:41Z

172.69.70.131:

{{comic
| number = 2034
| date = August 17, 2018
| title = Equations
| image = equations.png
| titletext = All electromagnetic equations: The same as all fluid dynamics equations, but with the 8 and 23 replaced with the permittivity and permeability of free space, respectively.
}}
==Explanation==

This comic gives a set of mock equations. 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. Most of the jokes are related to the symbols or "look" of most equations in the given field.

The comic makes jokes about the fields of kinematics, number theory, fluid dynamics, quantum mechanics, chemistry, quantum gravity, gauge theory, cosmology, and physics equations. Of course, all of the equations listed are not real equations (<math>\pi-\infty</math> and H2EAT are clearly jokes and making a mockery of the given field). As always, Randall is just having a laugh.

:<math>E=K_{0}t+\frac{1}{2}\rho{}vt^2</math>
;All kinematics equations
Most kinematics equations tend to make heavy use of constants, addition, powers, and multiplication. This specific equation resembles the actual kinematics equation d = vt + 1/2at^2, but replaces a (acceleration) with v (velocity) and replaces velocity with "K0", which is not a term used in kinematics.

:<math>K_{n}=\sum_{i=0}^{\infty}\sum_{\pi=0}^{\infty}(n-\pi)(i+e^{\pi-\infty})</math>
;All number theory equations
Randall jokes about how number theory often involves the use of summations. The use of ''π'' as an integer variable in the double summation is a joke, as ''π'' is essentially always used for the well-known constant 3.14159..., not a variable. The use of ''i'' as a summation variable '''is''' common, though it can also be confused with the imaginary unit √-1. The constants ''e'', ''i'', and ''π'', as well as the theoretical upper bound <math>\infty</math>, often appear in number theory equations.

:<math>\frac{\partial}{\partial{t}}\nabla\!\cdot\!\rho=\frac{8}{23}\int\!\!\!\!\int\!\!\!\!\!\!\!\!\!\subset\!\!\supset\rho\,{ds}\,{dt}\cdot{}\rho\frac{\partial}{\partial\nabla}</math>
;All fluid dynamics equations
Fluid dynamics equations often involve copious integrals, especially those over closed contours as done here, which are often the main telling factors of those equations to an outsider. The time derivative and gradient operator :<math>\nabla</math> are common in fluid dynamics, mostly via the Navier-Stokes equation, and the fluid density :<math>\rho</math> is one of the functions of central importance. The fraction 8/23 is a comically weird choice, but various unexpected fractions do pop up in fluid dynamics.

:<math>|\psi_{x,y}\rangle=A(\psi)A(|x\rangle\otimes|y\rangle)</math>
;All quantum mechanics equations
Quantum mechanics often involves some of the foreign-looking symbols listed, including {{w|Bra–ket notation|bra-ket notation}}, the {{w|Tensor product|tensor product}}, and the Greek letter Psi for a quantum state. Specifically, the left side of the equation is a ket state labeled Psi that depends on x and y (probably positions), while the right hand side may be an operator A that depends on the state Psi (it is very unusual to have such a dependence) acting on what looks like another copy of that operator which depends on the outer product of states labeled by x and y (again strange). A charitable interpretation could be that the second A is the eigenfunction A of the operator A. Normally this is clearly indicated by giving the operator a “hat” (^ symbol) or making the eigenfunction into a ket eigenstate, but since the equation is intentionally nonsense both A’s are left ambiguous. Also note that the bra-ket math is inconsistent here, as the left side is a ket, but the right side is just two A’s, which are either operators or functions but are definitely not kets.

:<math>CH_4+OH+HEAT\rightarrow{}H_2O+CH_{2}+H_2EAT</math>
;All chemistry equations
Chemistry equations use formulas of chemical compounds to describe a chemical reaction. Such equations show the starting chemicals on the left side and the resulting products on the right side, as displayed. Sometimes such an equation might optionally indicate that an {{w|activation energy}} is required, for the reaction to take place in a sensible timeframe, e.g. by heating. A reaction requiring heating is usually indicated by a Greek capital letter Delta (''Δ'') or a specified temperature above the reaction arrow, however this comic uses the "+ HEAT" term on the left side instead. The joke is that Randall interprets "HEAT" to be another chemical, which reacts with Hydrogen (H) to H2EAT, which is non-sensical, as heat is transferred energy here, not added matter. Regardless of this, Randall gets the {{w|stoichiometry}} of this equation correct, with the same number of all types of 'atoms' on each side of the equation.

:<math>SU(2)U(1)\times{}SU(U(2))</math>
;All quantum gravity equations
Quantum gravity uses mathematical {{w|Group (mathematics)|groups}} denoted by uppercase letters, as shown. {{w|Special unitary group|SU(2)}}, {{w|Unitary group|U(1)}}, and {{w|Unitary group|U(2)}} are all well-studied groups, though 'SU(U(2))' makes no sense. The lack of relator means this expression isn't an equation. Here is a possible pun, on "Sue you too... you won"... "Sue you, you too", though it's unclear how it fits in here.

:Sg=(-1)/(2ε̄) ið(̂ ξ0 ⨢ pε ρvabc⋅η0)̂ f̵a0 λ(ξ) ψ(0a)
;All gauge theory equations
Gauge theory is a subset of field theory. Most gauge theory equations appear to have many strange-looking constants and variables with odd labels.

:<math>H(t)+\Omega+G\!\cdot\!\nabla...\begin{cases}...>0\mathsf{\ (Hubble\ model)}\\
...=0\mathsf{\ (Flat\ sphere\ model)}\\
...<0\mathsf{\ (Bright\ dark\ matter\ model)}
\end{cases}</math>
;All cosmology equations
Cosmology is the science of the development and ultimate fate of the universe. The joke here may be pertaining to the different models accepted in the field of cosmology. H is the {{w|Hubble's law#Time-dependence of Hubble parameter|Hubble parameter}}, Ω is the universal {{w|Friedmann equations#Density parameter|density parameter}}, G is the {{w|gravitational constant}}, and Λ is the {{w|cosmological constant}}.

:Ĥ - u̧0 = 0
;All truly deep physics equations
The joke about the "truly deep physics equations" is that most of the universal physics equations are simple, almost exceedingly so. One example is Einstein's <math>E = mc^2</math>.

The title text is referencing the fact that the electric and magnetic fields are often explained to physics students using an analogy with fluid dynamics, as well as the fact that they do share some similarities (only in terms of mathematical description as three-dimensional vector fields) with fluids. The permittivity constant (represented with ''ε''0) and the permeability constant (represented with ''μ''0) are coefficients that relate the amount of charge required to cause a specific amount of electric flux in a vacuum and the ability of vacuum to support the formation of magnetic fields, respectively. They appear frequently in Maxwell's equations (the equations that define the electric and magnetic fields in classical mechanics), so Randall is making the joke that any surface integral with them in it automatically is an electromagnetism equation.

{{w|Approximate string matching|Fuzzy, or approximate, string matching}} is a technique used for searching strings (how a computer stores and manipulates writing) for specified values. Normal string matching would only find results that fit the search exactly. Fuzzy string matching instead finds results that are "close enough" by some metric. This is often used in search engines, as typos, misspellings, and inexact searches are commonplace.

If a list of potential nuclear missile targets were stored, and a fuzzy search was looking for "missile silos", the {{w|Missal of Silos}} would most likely be returned as a result--and subsequently, targeted with a nuclear missile. Why an 11th century piece of writing was a potential target for a nuclear strike is unknown. Missile silos are often thought to be the first targeting priority in event of a nuclear strike, in hopes of preventing retaliation from the target.

{{w|Cheyenne Mountain}} is a mountain in Colorado, which houses an underground compound (aptly named the {{w|Cheyenne Mountain Complex}}) designed to withstand a nuclear strike, armed with missiles of their own. {{w|Cheyenne, Wyoming}}, on the other hand, is the capital of Wyoming. While it does house a military airport, it is not home to any nuclear weapons.

Talk:2027: Lightning Distance

172.69.70.131:

Calculations I used:

t1=s/v1

t2=s/v2

Substract:

t1-t2=dt=s/v1-s/v2=(s*v2-s*v1)/(v1*v2)=s*(v2-v1)/(v1*v2)=s*dv/(v1*v2)

Therefore

s=(dt*v1*v2)/dv

I evaluated (v1*v2)/dv and it came to be 13.6 billion. Can someone verify it's correct? [[Special:Contributions/172.68.51.112|172.68.51.112]] 13:08, 1 August 2018 (UTC)

I used refractive index for visible light of 1.000277 (air at STP as opposed to 0C 1atm) and arrived at around 7.9 billion instead. Refractive index of 1.000337 is then required for the radio waves for the comic to be correct. [[Special:Contributions/172.68.11.221|172.68.11.221]] 13:46, 1 August 2018 (UTC)

:Do you mean 7.9 billion to convert to miles or to kilometers? Because my 13.6 bilion is to kilometers.

::I'm sure the actual comic is referring to miles and 5 billion was picked to match with the "divide by five" rule for miles. [[Special:Contributions/172.69.70.131|172.69.70.131]] 13:59, 1 August 2018 (UTC)

172.69.70.131:

Calculations I used:

t1=s/v1

t2=s/v2

Substract:

t1-t2=dt=s/v1-s/v2=(s*v2-s*v1)/(v1*v2)=s*(v2-v1)/(v1*v2)=s*dv/(v1*v2)

Therefore

s=(dt*v1*v2)/dv
