I got two things to say:
* What the heck is the "Woodward Hoffman textbook on organic chemistry"? I can't find it anywhere online.
*I think it's a reference to [https://archive.org/stream/WoodwardAndHoffmannTheConservationOfOrbitalSymmetryAcademicPressVerlagChemie1970/Woodward%20and%20Hoffmann%20The%20Conservation%20of%20Orbital%20Symmetry%20%28Academic%20Press%2C%20Verlag%20Chemie%2C%201970%29_djvu.txt]Conservation of Orbital Symmetry (1971)], whose chapter "Violations" starts with "There are none!" Unfortunately, the "Conclusions" chapter doesn't fully fit the criteria. [[Special:Contributions/162.158.63.196|162.158.63.196]] 17:23, 15 February 2020 (UTC)

Paper title: "Constructive proof of P=NP". Conclusion: "No further research is needed" ... because anyone who read this paper can get so rich they won't need to do any research for rest of life, spent on nice tropical island. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 00:58, 15 February 2020 (UTC)
: ... other paper with similar property: "Experimental disapproval of second thermodynamic law" -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 01:01, 15 February 2020 (UTC)

Can someone make a category called "Research" or "Research Papers"?

::I thought a similar one already existed, since there have been quite a few comics talking about scientific study papers. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 01:03, 16 February 2020 (UTC)

Here is a list of a bunch of papers that could have done this (but for some it might not have been known at the time): https://mathoverflow.net/questions/347540/what-are-examples-of-collections-of-papers-which-close-a-field [[User:Fabian42|Fabian42]] ([[User talk:Fabian42|talk]]) 02:16, 15 February 2020 (UTC)

Regarding topics that might reach a conclusion: The first subset that comes to mind is religious matters (e.g. "God works in mysterious ways -- let's not think about this too much.") The second subset that comes to mind is game theory regarding games that have been solved. (e.g. there's not much left to be said about tic-tac-toe.)

: Further research is needed to see why humans continue to play tic-tac-toe when it's so widely known how to avoid losing. And into how anyone ever wins. And why on earth Google has an online version, with 3 different difficulty levels. Seriously though, there is actual research into how to have the best chance of beating a player who isn't very good (meaning someone who is bad enough to lose occasionally), which involves not only game theory, but also psychology about what mistakes an opponent is most likely to make. Finally, there are newer, more complex, variants, such as playing on a 4x4 grid or in 3D, and new ones can always be developed so that the field is never closed.[[Special:Contributions/172.68.47.162|172.68.47.162]] 00:08, 16 February 2020 (UTC)

2259: Networking Problems

}}

==Explanation==
{{incomplete|Created by an ODD-NUMBERED PACKET CLAPPING ITS HANDS. Please mention here why this explanation isn't complete. Do NOT delete this tag too soon.}}

Computer problems are frequent and can be difficult to solve. Networking problems in particular can puzzle even seasoned people and sometimes seem to have arbitrary issues causing them. {{w|Network packet|Packets}} are units of data transfer used in computer networking, and one measure of network performance is ''lag'', the amount of time it takes for data to travel from one point to another (and perhaps back); saying a packet's transmission is 'laggy' means it is unacceptably slow.

Lag in packet transmission and other network performance measures can appear quite random. Just to start with, your ISP may be engaged in traffic shaping, which can do very weird things indeed to your packets (making the first megabyte of a transfer faster than any other, for example); now imagine that your ISP's ISP (usually known as an "Upstream Provider") is engaged in something similar, and you begin to see the scale of the problem. Because humans are wired to perceive patterns, they will {{w|Apophenia|find them even in random data}}, a fallacy that Cueball is (probably) suffering from here. He variously attributes the network behavior he sees to the packet number being even vs. odd, packet arrival time being before vs. after noon, and packet arrival day being today vs. yesterday (such a pattern would make sense if it were merely "every other packet" regardless of odd or evenness, but that still leaves the other "patterns" Cueball is seeing).

These non-existent patterns that Cueball is 'finding' are driving him mad, so much so that he says he believes in ghosts now. The statement of belief in ghosts may be a reference to the intermittent or fluctuating nature of the network issues being caused by mischievous spirits or malevolent poltergeists. Ghosts generally are not concerned with expressions of belief, but there are some religious traditions that include group clapping and chanting. Many works of fiction depict a future or alternate history where {{tvtropes|MachineWorship|machines are worshiped as gods or spirits}}, such as the Adeptus Mechanicus of ''{{w|Warhammer 40,000}}''. Some of this terminology can be found in present-day IT and other support personnel, including references to "{{w|Daemon (computing)|daemons}}" and "[http://catb.org/jargon/html/B/black-magic.html black magic]".

The title text continues Cueball's maniacal attempts at self-assurance, with him alluding to J.M. Barrie's play ''{{w|Peter Pan}}'' by saying that latency falls every time you "CLAP YOUR HANDS AND SAY YOU BELIEVE". In the play, Peter Pan says "If you believe in fairies, wave your handkerchiefs and clap your hands." A more mundane explanation of the network behavior Cueball is experiencing might be that it is random but he's seeing a pattern anyway, or that there is a loose connection or trace and the vibration of clapping and speaking in the vicinity of the equipment in question closes the connection.

:[A chart is shown with one horizontal line with 13 ticks (the first larger) and ending in an arrow. There are three labels along the line, at the start in the middle an towards the end before the arrow. Below are two clouds in gray with labels. The first cloud is long and it is getting thinner towards the right. It goes between the first and second label above the chart. The second blob is smaller and of equal thickness and it goes from the last label towards right. Above the chart is a heading and a subheading:]

:[Below the chart, only in the right part of the comic is a comic drawing. Cueball is kneeling before a rack of servers. One of the server blades is extended and connected by a cable to a laptop sitting on a box, which Cueball is using. Behind Cueball, there is a wireless router sitting on a stool, which is connected by a cable to another wireless router sitting on the floor, which is connected to another laptop. From behind him to the right an off-panel voice emanates from a starburst at the edge of the panel.]

Talk:2250: OK/okay/ok

2020-01-03T23:06:12Z

162.158.134.142:

I think this should have been a table. Put spellings down the side (I've seen a lot of "oki" online; maybe "A-OK" too, or some humorous misspelling) and possible permutations of punctuations and capitalisation across the top. I want to know how "o.k.ay." makes you sound :p
[[User:Angel|Angel]] ([[User talk:Angel|talk]]) 17:41, 3 January 2020 (UTC)
:But when you do a single word response, it should just be, "k".
:[[User:Hax|Hax]] ([[User talk:Hax|talk]])
:If it's not capitalized, I'm definitely imagining the person making clucking noises, even if I ''know'' that's not what they meant... Doesn't ''everybody'' read "ok" phonetically, as "ock", as in grok? ;S
:[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 21:42, 3 January 2020 (UTC)

As of this writing, the title text is wrong. I don't know how to edit it. The current explainXKCD version ends with ("oK".). But the xkcd website ends with ("oK.") The location of the period within the quote changes the meaning of this comment. [[User:Agrasin|Agrasin]] ([[User talk:Agrasin|talk]]) 20:43, 3 January 2020 (UTC)
:Good catch! I edited it. I was the one who put it in wrong in the first place as well. I had to insert the quotes manually, when I copy-pasted the title text from the inspect tool of xkcd.com and made this error. Things like the title text or the date can be edited easily when you use the edit button on top of the page instead of the small one at the explanation/transcript. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 21:13, 3 January 2020 (UTC)
:The period's placement does not necessarily change the meaning of the sentence as its inclusion within the quotation marks does not imply it is part of the quote. Punctuation immediately following a quote goes inside the quotation marks under English grammar. [[Special:Contributions/172.68.174.112|172.68.174.112]] 21:23, 3 January 2020 (UTC)
::That's a ridiculously bad rule & I'd hope nobody actually does that. Punctuation should only go inside the quotation marks if it's part of the quote. To put punctuation in where it wasn't used muddles whether the punctuation is part of the quote or part of the sentence containing the quote, & offers no possible benefit to comprehension. Bad rule: Don't do that.
::[[User:ProphetZarquon|ProphetZarquon]] ([[User talk:ProphetZarquon|talk]]) 21:37, 3 January 2020 (UTC)
:::Totally agree although I suspect that english grammar is not supposed to be logical. Also, I think using "oK" would be good idea. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 23:03, 3 January 2020 (UTC)
:::However, it looks much nicer and mimics proper handwriting, where the comma sign is directly underneath the quotation mark. It's considered proper form for American English, whereas Brits put it outside.
:::[[Special:Contributions/162.158.134.142|162.158.134.142]] 23:06, 3 January 2020 (UTC)
::No, that's only for comma signs. Periods go inside if it's a part of the quote, outside if it isn't, and in both places if you end your sentence with a quote. "This quoted sentence ends with a period.".

Talk:2007: Brookhaven RHIC

2018-06-16T07:03:37Z

162.158.134.142:

I think the correct explanation has to do with relativistic mass. Accelerated gold ions will have an increased (relativistic) mass. Therefore, the gold coming out of the accelerator will have a higher value than the input. You just have to sell by mass. --[[Special:Contributions/172.68.78.22|172.68.78.22]] 16:14, 15 June 2018 (UTC)
:Yeah, we need to calculate the increase of mass at 99.99, 99,999, 99,9999 percent of the speed of light. I didn't check but I'm curious how many 9s we need to reach the mass of the Earth for a single gold nuclei. Nevertheless the speed is zero again when you collect them, or you have to move at the same speed, but than you can't measure that increase because you're in the same reference -- and back on Earth your own mass would have grown out far beyond the mass of our Milky Way. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 18:11, 15 June 2018 (UTC)
::Mass is an invariant quantity. What is increased is the total energy, E=sqrt(p^2+m^2). As previously mentioned, when they are delivered they would have to be measured in a comoving frame in which case no increase in "mass" would be noticed.-- [[Special:Contributions/162.158.146.70|162.158.146.70]] 20:46, 15 June 2018 (UTC)
:::Sorry, you know what ''invariant'' means in physics? And you can't sum p and m (simply squared both) by using the Einstein conventions c=1, it's in fact E2=m4+p2 -- I fear most people still don't understand. --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:02, 15 June 2018 (UTC)
::::Comes across a bit condescending considering m^2c^4=(mc^2)^2, not (mc)^4. The mass is the rest mass, which is always the same, considering it is measured at rest. It is a misnomer to call the total energy the mass. The physics you're describing is correct, I just take issue with the wording. I'm sorry if I didn't make myself clear enough. --[[Special:Contributions/162.158.146.70|162.158.146.70]] 22:29, 15 June 2018 (UTC)
Isn't a typical cash-for-gold store where you would take your gold and walk out with cash for your gold? It sounds like Randall's proposal is gold-for-cash stores instead. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 19:03, 15 June 2018 (UTC)
: It makes sense if his proposal is to sell the gold to the stores, where he would just need the stores to agree to buy the high speed particles. I thought he was suggesting consumers would buy the excess gold particles in the stores, but that's probably not what he meant. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 19:14, 15 June 2018 (UTC)

My first thought here was that he was proposing a gold-ion particle beam weapon. [[Special:Contributions/162.158.106.240|162.158.106.240]] 20:10, 15 June 2018 (UTC)

The {{w|Relativistic Heavy Ion Collider}} is a particle accelerator designed to collide gold ions together at incredibly high speeds. This is normally done to study particle physics - the high-energy collisions allow us to learn more about how subatomic particles behave.

[[Randall]] proposes that, instead of using the beam of gold ions for particle collisions, it should be diverted and sold at cash-for-gold stores to make money. The joke is that because they are traveling at relativistic speeds, the mass of the particles being sold will be much more than the mass of the ions being supplied to the collider's input. However, it would be very difficult to sell a beam of charged particles{{Citation needed}}. The amount of gold involved is below microscopic scales. This is probably why Brookhaven rejected Randall's proposal. Randall has done many comics describing impractical{{Citation needed}} research proposals.

The title text imagines the owner of the stores complaining about the sale, not because of impracticality, but because Randall tries to sell gold ions with the entire positively-charged nucleus of the gold atom with all 79 electrons stripped from it instead of normal, electrically neutral gold atoms. And this is also a pun on the word "charges", which could refer to {{w|electric charge}} or to {{w|criminal charge|criminal charges}}.

1878: Earth Orbital Diagram

2017-10-03T12:55:52Z

162.158.134.142: /* Labels and Their Astronomical Meanings */

{{comic
| number = 1878
| date = August 18, 2017
| title = Earth Orbital Diagram
| image = earth_orbital_diagram.png
| titletext = You shouldn't look directly at a partial eclipse because of the damage that can be caused by improperly aligning the solar-lunar orbital plane with the orbital bones around your eye.
}}

==Explanation==
{{incomplete|Still needs a review and the picture without the labels needs an explanation. Do NOT delete this tag too soon.}}

This comic is the third of five consecutive comics published in the week before the {{w|solar eclipse}} occurred on Monday, {{w|Solar eclipse of August 21, 2017|August 21, 2017}} which was a total solar eclipse and visible in totality within a band across the {{w|contiguous United States}} from west to east. The other comics are [[1876: Eclipse Searches]], [[1877: Eclipse Science]], [[1879: Eclipse Birds]], and [[1880: Eclipse Review]].

The comic claims that the reason that eclipses don't happen every month is simple to understand by looking at an orbital diagram. Ironically, the cartoon has so many parts and labels that it is far more difficult to understand than is implied. While the graph itself is based on {{w|Orbital elements|astronomical definitions}}, all the labels are nonsense in this context. In effect, the comic is a new take on a common joke in which a person asks a scientist a question, the scientist begins by saying "It's really quite simple", then proceeds to give a very lengthy and highly technical explanation that non-scientists would not be expected to understand. Diagrams for eclipses commonly include things that laypeople may not find relevant, without explanation, such as the umbra and penumbra.

All of the labels in the diagram are complicated words or phrases. Some are related to orbital mechanics (e.g. "equinox" and "perihelion"), while others are wholly unrelated or even made up. Each label is nonsensical in its place in the diagram. Compare/contrast with the standard {{w|Kepler orbit|Kepler Orbit}} diagram.

The title text references warnings to not look directly into the sun, but parodies those warnings by referring to 'orbit', the anatomical term for the eye socket.

===Labels and Their Astronomical Meanings===
All items are not drawn to scale. Neither the sizes of the celestial objects are that similar as shown nor the orbits are. The real scales are shown in this table:
{| class=wikitable style="text-align:right;"
!
! real (in km)
! to scale

|-
| Sun (radius)
| 695,700
| basketball

|-
| distance Earth-Sun
| 149,600,000
| length of a large truck (26 meters)
|-
| Earth (radius)
| 6,371
| pinhead (1 mm)
|-
| Moon (radius)
| 1,737
| pin (0.3 mm)
|-
| distance Earth-Moon
| 384,399
| small necklace (6.6 cm)

|}
When the distance Sun-Earth is scaled to one meter or below neither Moon nor Earth can be seen by the human eye.

;Arctangent
*{{w|Arctangent}} is the inverse function of the tangent function of trigonometry. You can determine a non-right angle of a right triangle by taking the arctangent of the length of the opposite side divided by the length of the adjacent side.
*The angle shown in the comic has no astronomical meaning.

;Astral plane
*The {{w|Astral plane}} is a plane of existence in various esoteric theories. It features prominently in {{w|Dungeons & Dragons}} cosmology, connecting the various other planes of existence.
*The picture shows the {{w|Orbit_of_the_Moon|lunar orbital plane}}, the plane in which the Moon orbits the Earth, tilted about 5.1 degrees from the ecliptic.

;Declension
*{{w|Declension}} is the inflection of nouns in a language. In {{w|Latin}} declension and declination are both called ''{{w|la:Declinatio|Declinatio}}''. In this comic, however, it might be a portmanteau of declination and (right) ascension.
*In astronomy, the {{w|Declination|declination}} is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system. It is measured north or south of the celestial equator, like the geographical latitude on Earth. But in the picture the label is at the angle for the axial tilt of the Earth.
*And the {{w|Right_ascension|right ascension}} is the angular distance measured eastward along the celestial equator from the vernal equinox to the hour circle of the point in question.

;Determinant of the date of Easter
*In Western Christianity {{w|Easter}} always falls on the first Sunday after the first ecclesiastical full moon after the beginning of spring (equinox). The ecclesiastical full moon is determined by a calendar that approximates the actual time of the full moon, Thus the date of easter is defined by a combination of a solar and a lunar calendar. The position of that angle isn't that bad but it should be not more than 30 degrees (slightly more than one month.)
*In mathematics, the determinant is a function of numerical matrices. In this context, however, it apparently refers to something that directly determines the date of Easter.

;Dimples of Venus
*The {{w|Dimples of Venus}} are indentations sometimes visible on the human lower back.
*In astronomy the {{w|Belt of Venus}} is a shadow cast by the Earth visible in its atmosphere.

;Enceliopsis
*{{w|Enceliopsis}} are small genus of flowering plants in the daisy family, appropriately known as "sunrays".
*In astronomy this point has also no specific meaning. But {{w|Enceladus}} is a moon around {{w|Saturn}}.

;Equinox / Solstice
{{w|Equinox}} and {{w|Solstice}} have very different meanings:
*An Equinox is one of two instants in the year when the sun is exactly over the equator; the length of day and night are very nearly equal that day at all locations on the planet, and it is potentially the first day of Spring or Autumn, depending on the time of year, in which hemisphere (Northern vs Southern) the observer is located, and which definition of seasons one uses.
*A Solstice is one of two instants in the year when the sun's angle is maximally far from Earth's equator; when one occurs, the length of the day or night is shortest or longest (depending on whether one is in the northern or southern hemisphere), and (in the United States) it marks the first day of summer or winter.

Both types occur because the Earth's rotation axis is tilted (at 23.4 degrees) from its orbital plane (ecliptic) about the Sun.

Jokingly insisting that two different terms are American/British variants of the same word has been the topic of [[1677: Contrails]].

;Hypothecate
*{{w|Hypothecate}} is a legal verb that means something similar to "make a mortgage".
*The {{w|hypotenuse}} is the longest side of a right-angled triangle. Here it is an unrelated length, approximately equal to the diameter of the sun (half the angular size of the sun times twice the distance to it).

;Obsequity
*Obsequity means the state of being obsequious (showing an indecorous willingness to obey or serve, or "sucking up").
*In astronomy the correct word is {{w|Obliquity}}, meaning an axial tilt.

;Perihelix
*This is a portmanteau of helix and perihelion.
*The {{w|perihelion}} is the point in a elliptical solar orbit that is closest to the Sun.

;Prolapse
*A {{w|Prolapse}} is a medical condition in which an internal organ is slipped forward or down.
*{{w|Retrograde and prograde motion}} are terms used to describe the apparent motion of celestial objects through the sky.

;Sagittal plane
*The {{w|Sagittal plane}} is an anatomical plane, dividing the body in left and right.
*The correct label in the picture would be the {{w|Ecliptic plane}}. The plane the Earth orbits the Sun.
*{{w|Sagittarius (constellation)|Sagittarius}} is one of the stellar constellations of the Zodiac. The center of the Milky Way lies in this constellation.

;Solar plexus
*The {{w|Solar plexus}} is a network of nerves located in the abdomen. It was the name of [[64: Solar Plexus]].
*{{w|Solar}} is an adjective referring to the Sun, the star in our solar system.

;Tropopause
*The {{w|Tropopause}} is the boundary in our atmosphere between the troposphere and stratosphere, defined as the boundary where air ceases to cool with increasing elevation. It is 9-17 km above sea level, not the thousands of kilometers as depicted here.
*The label appears to point at the orbit of the moon.

;Angle between the Astral and the Sagittal Planes
* The angle depicted is the inclination of the moon orbit. The planes are marked with nonexistent symbols, derived from Greek letters. The lunar orbit plane is labeled by a mixture of a ''nu'' (ν) and a ''gamma'' (γ), the ecliptic is labeled with a double ''chi'' (χ), and the angle between is marked with a ''phi'' (ϕ) but having two vertical lines.

;Errata
* Errata are corrections in a published text (e.g. a newspaper article) issued after the publication.
* The angle depicted lies between the direction from Earth to the Sun in the ecliptic and the line where the lunar orbit plane crosses the ecliptic. When this angle would be zero AND the Moon is between the Sun and Earth a total eclipse would occur. This is they only part of the diagram fulfilling slightly Randall's promise on top of the picture.

==Explanation for "Why isn't there a (solar) eclipse every month?"==

If the plane of where the Earth orbits the Sun and where the Moon orbits the Earth were completely aligned, then there would be a solar eclipse at every new moon (once every {{w|Orbit_of_the_Moon#Lunar_periods| 29.5 days}}) and a lunar eclipse at every full moon (half a lunar period about 14.7 days after a New Moon). However, the plane in which the Moon orbits the Earth is tilted with an inclination of 5 degrees relative to that of the ecliptic plane (the plane defined by the Earth's orbit around the Sun). Eclipses are only possible during two eclipse seasons each year (half a year apart) where for a period of 31 to 37 days the Sun is nearly aligned with the two points in the tilted Earth-Moon plane where the Moon crosses the ecliptic plane. During an eclipse season at the time of a new moon there will be solar eclipses visible from certain locations and during full moons there will be lunar eclipses.

[[Image:Eclipse_Diagram.jpg]]

The real explanation of eclipses is evident from this xkcd comic, but is labeled with a fictional character similar to a Greek phi but with two vertical lines; the remaining labels also do not contribute to this explanation and exist only to distract or misinform or entertain the reader.

:[An orbital map of the Earth is shown. The Sun is in the center, the Earth is at the right bottom, and the Moon is left below the Earth.]
:'''Why isn't there an eclipse every month?'''
:This is a common question! The answer is made clear by a quick look at the Earth's orbital diagram:

:[Label Sun:]
:Solar plexus

:[Label on the Earth's plane:]
:Sagittal plane

:[Labels on Earth's orbit (beginning at the Earth counterclockwise):]
:Perihelix, Declension, Obsequity, Hypothecate, Enceliopsis, Equinox (''Solstice'' in British English)

:[Two angles in the plane are labeled as:]
:Determinant of the date of Easter, Arctangent

:[The plane of the Moon is pictured in a small angle to the Earth's plane and named Astral Plane. The angle is presented between two lines (Greek Nu or Gamma and a double Greek Chi) and identified by a character that looks similar to a Greek Phi but with two vertical lines.]
:[The labels at the Moon's path are:]
:Tropopause, Prolapse, Errata.

:[An arrow points to the Earth at the zero meridian on the equator. The label reads:]
:Dimples of Venus
