Hitting next on this page brings you to comic #768 titled 1996. This comic is #1995. I thought that there was an extra comic today at first. [[User:MrNinja|MrNinja]] ([[User talk:MrNinja|talk]]) 14:58, 18 May 2018 (UTC)<br />

<br />
==Explanation==<br />
<br />
Many politicians and organizations in the United States have taken to using aggressive fundraising campaigns by email to seek campaign contributions.<br />
<br />
This comic shows a caricature of many people's email inboxes right now. Signing a petition or expressing interest in a cause can lead to being added to a myriad of mailing lists for similar groups, all looking for support. It seems Randall has a history of donating to questionable candidates with poorly thought out campaigns, and that's gotten him onto some interesting email lists. The emails get more and more absurd as the list goes on. For example, the last one combines a request for campaign contributions with the infamous Nigerian Prince phishing scheme.<br />
<br />

! E-mail Body !! Explanation<br />
|-<br />
|'''Donate now.''' It's crunch time, and we're low on cash. If you chip in just $5 by midnight, we...<br />
|This is the classic formula, and may be a real example. It is always "crunch time" during a campaign (at least between filing for candidacy and election day), and campaigns are always "low" on cash relative to the unlimited funding they would prefer. The ends of financial reporting periods, often at midnight, are conflated with "deadlines" of significant consequence. Further, the donation requested is less about the actual money - even if $5 each from several thousand voters can add up - but to get a donor to have their money placed on a candidate, making it more likely that donor will vote for the candidate (via encouraging [https://en.wikipedia.org/wiki/Sunk_cost#Loss_aversion_and_the_sunk_cost_fallacy the "sunk cost" fallacy]).<br />
|-<br />
|'''Donate $35.57 now!''' Our data team has determined that we should ask you for $35.57 to optimize the...<br />
|While fundraisers will try and work out how to gain money as possible, they would never explain this to their supporters. Such a precise amount would come about as a result of running the numbers through a computer simulation, and the obvious lack of humanity behind the calculated dollar amount would probably be offputting to a lot of would-be supporters. This may also be an exaggeration of Senator Sanders' presidential campaign, which sent e-mails asking for $27 because it was the average amount of their contributions up to that point.<br />
|-<br />
|'''Help.''' Our campaign made some mistakes and we need a lot of money ASAP. Any kind, but cash is...<br />
|This email is honest about the campaign's incompetence, but is not likely to get much sympathy except from those already sympathetic to the candidate. Any campaign reduced to this level has probably already lost, though.<br />
|-<br />
|'''Washington is broken.''' When I win, I'll look those other senators in the eye and tell them: "Jobs." Then I...<br />
|This may be another real example. This appeal to emotion promises specific action that is unlikely to accomplish much, and is honestly probably unlikely to happen even if the candidate wins, while suggesting the candidate vaguely cares about issues of importance to most voters, as measured by the polls. The humor here comes from the fact that the candidate promises to simply say the word "jobs", as if that means something by itself.<br />
|-<br />
|'''Hopeless.''' It's bad. Really bad. If you don't chip in now, the darkness spreading across the land will...<br />
|This is a favorite of moral campaigns, on both sides of the debate. Pro-life and pro-choice are both really fond of claiming that if their side doesn't get more money, the evil on the other side will win; but it is used in other moral campaigns as well.<br />
|-<br />
|As the first woman to fly a fighter jet through our state's formerly all-male university, I learned...<br />
|Normally one would be the first ''from'' a university to do something.<br />
|-<br />
|'''We're broke.''' No paid staff. No ads. And the cafe has told us to stop using their wifi to send fundraising...<br />
| The poor church mice syndrome is also a big favorite of religions...even those you don't think are religions, like atheists.<br />
|-<br />
|When Amy decided to run for Congress, I was like "Huh?" but I checked Wikipedia, and apparently it's a branch of...<br />
|The reader would expect that the writer expressed surprise because they weren't expecting Amy to run for Congress, but the actual reason is because they didn't know what Congress was. If the aim is indeed fundraising, as the comic's title would imply, this message is very likely to give very poor (no pun unintended) results. While the familiar tone could be a communication strategy (although you might want to look serious and professional when asking for money), the author openly states not knowing what the campaign was about until recently, which would make potential donors doubt that their money would be put to good use.<br />
|-<br />
|-<br />
|'''Are you familiar''' with the Dutch painter Hieronymous Bosch? His work illustrates my opponent's plan for...<br />
|The works of [https://en.wikipedia.org/wiki/Hieronymus_Bosch Hieronymus Bosch], which are famous for depictions of [https://en.wikipedia.org/wiki/Hell Hell] and [https://en.wikipedia.org/wiki/Limbo Limbo] as brutal places of highly imaginative torments.<br />
|-<br />
|Being a single mom running a small business while going to law school while being deployed to Iraq taught me...<br />
|These are tasks which are unlikely to be able to accomplished simultaneously, and seem to be in line with typical campaign promises.<br />
|-<br />
|'''I will lead the fight''' against the big banks, special interests, the Earth's climate, and our children. I...<br />
|A fight "against our children" may be a reference to a popular [https://en.wikipedia.org/wiki/Bushism Bushism]<br />
|-<br />
|'''Wow.''' Have you seen this video of the squirrel obstacle course? Incredible! Anyway, I'm running because I...<br />
|A typical form of {{w|clickbait}}.<br />
|-<br />
|'''Outrageous.''' Granted, this was a few years ago, but did you hear what President Ford said about...<br />
|When a politician makes an offensive comment, it's common for the politician's opponents to send out fundraising emails pointing out the politician's offensiveness as a reason to give money to an opponent. Here, the sender's reaction and e-mail fundraising effort appears to be unusually delayed, as it refers to an alleged comment by {{w|Gerald Ford}}, whose term as President of the United States ended in 1977 and who died in 2006.<br />
|-<br />
|'''Whoops.''' Due to a typo, we spent months running attack ads against Tom Hanks. Now, we need to make up for...<br />
|The email apologises for running months of attack ads against American actor {{w|Tom Hanks}}. Hanks is generally a popular and uncontroversial figure,{{Citation needed}} making him an unusual target for attack ads.<br />
|-<br />
|'''They say we can't win-''' that we're "underdogs" with "no money" who "lost the election last week." But they don't...<br />
|May refer to [https://en.wikipedia.org/wiki/Roy_Moore#U.S._Senate_special_election_campaign Roy Moore's attempts to overturn his loss in the December 2017 election for one of Alabama's US Senate seats], which came about a month before this comic and made national headlines. After the initial election count had him losing, he demanded a recount. That initial count said he had lost by a large enough margin that Alabama law required him to pay up front for a recount, and his campaign did not have enough funds available.<br />
|-<br />
|'''Our campaign's only chance''' is to seduce Jennifer ActBlue, heir to the ActBlue fortune. For that, we need a fancy...<br />
|This e-mail alludes to [https://secure.actblue.com/ ActBlue], a political action committee that collects donations online for Democratic candidates. In reality, there is no ActBlue family nor any "Jennifer ActBlue" who is the heir to its fortune; the name ActBlue comes from the words "act" and "blue", referring to the {{w|Red states and blue states|color currently associated with the Democratic Party}}. <br />
|-<br />
|'''Doom.''' Where is the horse and the rider? Where is the horn that was blowing? They have passed, like rain on...<br />
|This is an excerpt from {{w|J. R. R. Tolkien|Tolkien's}} poem ''[http://tolkiengateway.net/wiki/Lament_for_the_Rohirrim Lament of the Rohirrim,]'' appearing in ''{{w|The Two Towers}}'':<br /><br />
Where now the horse and the rider? Where is the horn that was blowing? <br /><br />
Where is the helm and the hauberk, and the bright hair flowing? <br /><br />
Where is the hand on the harpstring, and the red fire glowing? <br /><br />
Where is the spring and the harvest and the tall corn growing? <br /><br />
They have passed like rain on the mountain, like a wind in the meadow; <br /><br />
The days have gone down in the West behind the hills into shadow. <br /><br />
Who shall gather the smoke of the dead wood burning, <br /><br />
Or behold the flowing years from the Sea returning?<br />
|-<br />
|'''Warmest greetings.''' I am the crown prince of Nigeria. I am running for Congress because I believe that...<br />
|The opening line is designed to sound like spam for an {{W | Advance-fee scam}}. These scams typically involve impersonating someone rich, often a Nigerian prince, who claims to be in trouble and promises to share a large sum of money if the victim helps him by sending a small fee in advance electronically. However, the second sentence of this email switches to sounding like a political fundraising email instead of an outright scam. This is either to establish a degrading comparison between flagrant scams and fundraising emails, or just to create a bait-and-switch joke.<br />
|-<br />
|The establishment doesn't take us seriously. You know who else they didn't take seriously? Hitler. I'll be like him, but a GOOD guy instead of...<br />
|A candidate who compares himself to {{w|Hitler}}, even when promising to be GOOD instead, will probably not get many votes. The title text does however conform to {{w|Godwin's law}}.<br />

Hey, an early comic that I understand! Typed up a transcript (though the description of the first panel was already there, and the empty explanation already had the Incomplete Explanation set as "Created by a LEPRECHAUN"), but using an iPad and typing in Notes to avoid editing conflicts, so I can't see the comic while I'm typing. So the inherent magic of the Telephone Game comes into play, where the mind likes to summarize and put into different words, LOL! I think I managed to get it completely accurate, though. I'll see if I can come up with an explanation shortly. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 07:10, 19 January 2018 (UTC)<br />

If you think about leprechauns while thinking about pots of gold then there will indeed be leprechauns at both ends.[[Special:Contributions/162.158.166.125|162.158.166.125]] 08:09, 19 January 2018 (UTC)<br />

I don't think that the part about solar gold volume is correct. The density used only applies to gold in solid state in room temperature, and the Sun is neither. In a way, gold indise Sun has the volume of the Sun itself. [[Special:Contributions/162.158.90.168|162.158.90.168]] 10:41, 19 January 2018 (UTC)<br />
: Yes I realized that a few minutes after posting my original edit, and added a parenthesis to explain that I used the volume that much gold would have on Earth-like conditions. Not that the fact has any concrete application anyway, but I thought it would show that the claim that there is more gold in the Sun than water on Earth can't simply be pictured as an ocean volume of gold. Maybe there's a sea somewhere that's about the right volume and you could say "taking all the gold from the Sun would fill <that particular sea>" [[Special:Contributions/141.101.88.16|141.101.88.16]] 11:21, 19 January 2018 (UTC)<br />

Leprechauns live on the night side of the Sun to avoid being incinerated, that's why we can't see them from this side.<br />

:The night side... Of the sun... Is there a cartoon about this? I feel like there needs to be a cartoon about this. Just one observation: On the night side of the sun, there's no moon? Or if there is, what's lighting it up? ;D This is even better than the "dark" side of the Moon.<br />

I think the logic of the title text is: gold is at the other end of the rainbow is there, because in that moment the person (his/her brain) is thinking about the gold. To put in a dumber way: when you think about gold, then gold is in your brain, ergo if your brain is one end of the rainbow, and you're wondering if there's gold at the end of the rainbow, then in a self-fulfilling way, it is.

I'm pretty sure the numbers are completly wrong, 0.3 parts per trillion probably comes from [https://www.quora.com/Is-there-any-gold-in-the-sun-If-so-how-much-gold-could-be-contained-in-it here] (because the same article was used as a reference at some point in the history of the explanation), but I think this is the ratio of atoms, not mass. The answer on quora uses the same value of 0.3 parts per trillion but instead of 6*10^17 kg of gold, deduces from that number that there is 10^20 kg of golds. One atom of gold is ~195 times as heavy as one atom of hydrogen, and since the Sun is mostly hydrogen and also some heavier elements, the mass of gold over the average mass of atoms in the Sun should be a little below 195. The ratio between 10^20 and 6*10^17 is 167.<br />
There's still a ratio of 20 between that value (10^20 kg) of the mass of gold on the sun and the one [https://www.wolframalpha.com/input/?i=(abundance+gold+sun)+*+(mass+sun) from wolframalpha], and I'm quite expecting Randall to have used the latter, which is of 2 [https://en.wikipedia.org/wiki/Names_of_large_numbers quintillion] tons of gold on the Sun, IE "quintillions of tons" as expressed by Megan. Maybe that value is wrong, but I think it should be mentionned to show that Randall probably didn't just make up a number.

:This is one of those cases where the phrase "Orders Of Magnitude" comes in, LOL! Kind of glad someone else beat me to providing an explanation now, not my goof. LOL! [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 08:22, 19 January 2018 (UTC)<br />

I don't think that the part about solar gold volume is correct. The density used only applies to gold in solid state in room temperature, and the Sun is neither. In a way, gold indise Sun has the volume of the Sun itself. [[Special:Contributions/162.158.90.168|162.158.90.168]] 10:41, 19 January 2018 (UTC)<br />
: Yes I realized that a few minutes after posting my original edit, and added a parenthesis to explain that I used the volume that much gold would have on Earth-like conditions. Not that the fact has any concrete application anyway, but I thought it would show that the claim that there is more gold in the Sun than water on Earth can't simply be pictured as an ocean volume of gold. Maybe there's a sea somewhere that's about the right volume and you could say "taking all the gold from the Sun would fill <that particular sea>" [[Special:Contributions/141.101.88.16|141.101.88.16]] 11:21, 19 January 2018 (UTC)</div>141.101.88.16https://www.explainxkcd.com/wiki/index.php?title=1944:_The_End_of_the_Rainbow&diff=1512641944: The End of the Rainbow2018-01-19T10:39:14Z<p>141.101.88.16: /* Explanation */ don't know the density of gold in the Sun</p>

Cueball and Megan are having a discussion. Megan brings up the myth that at the end of every rainbow lies a leprechaun's pot of gold. Instead of claiming that leprechauns and their gold don't exist, Cueball refutes that technically, rainbows are circles, so they do not have an end.<br />
<br />
However, Megan then expands on the scientific explanation Cueball is stating. She states that if one considers the path light takes to form a rainbow, then it forms a two-cone structure, where the Sun (the vertex of the outer cone) emits light rays that move towards the Earth (forming the faces of the outer cone), then reflect off of water droplets located at just the right angle (the circular base) to reach our eyes (the vertex of the inner cone ). Thus, such a rainbow structure ''can'' be said to have "ends", represented by the vertices of the two cones: one at the eye of the viewer, and another at the light source.<br />
<br />
Megan then says that the Sun is indeed a pot of gold. The Sun is [http://www.wolframalpha.com/input/?i=gold+sun+abundance 1*10^-7 percent gold] (one gram of gold for every billion grams of Sun), so if we multiply that by the mass of the Sun we get that the Sun contains [http://www.wolframalpha.com/input/?i=(sun+composition+gold)+*+(mass+of+sun) 2x10^21 kg] of gold; far more than a hypothetical leprechaun's pot of gold. Using that same percentage, you can [http://www.wolframalpha.com/input/?i=(gold+sun+abundance)*(sun+mass)%2F(volume+oceans+*+water+density) compute the ratio of gold in the Sun against sea water on Earth] and find a ratio of around 1.5. While the two values are pretty similar, this confirms Megan's claim that there is more gold in the Sun than water in the oceans mass-wise. Gold being far denser than water, if you [http://www.wolframalpha.com/input/?i=(volume++oceans)%2F((gold+abundance+sun)*(mass+sun)%2F(density+gold)) compare the two volumes] (using the volume the gold would have on the surface of Earth, the temperature and pressure in the Sun could make it vary greatly) then the oceans' waters beat the Sun's gold by a factor 13. <br />
<br />
Cueball then asks about leprechauns. Megan replies that the leprechauns all died when the Sun formed, implying all the gold in the Sun is actually the remnants of leprechaun gold. However, she does not consider the explanation where the leprechaun is on the other end of the rainbow...<br />
