Talk:2325: Endorheic Basin

Explain xkcd: It's 'cause you're dumb.
Jump to: navigation, search


I think it is a funny comic, but the way water acts towards Beret Guy has nothing to do with what happens in an Endorheic basin. And also if he attracts water more than gravity, then a siphon is no help at all to get rid of the water. A pump would be needed that could make a larger pull then gravity. But the name is just something Beret Guy gives it. And since he is the only hydrophilic person in the world it is hard to say how it will work for him. But given that Randall named the comic it seems to me that either he did not care about this, did not think about it correctly, or else, also a possibility, I do not understand these concepts well enough --Kynde (talk) 22:49, 26 June 2020 (UTC)

I sort of disagree with Kynde. I think the idea here is that Beret Guy is a local low point where water flows toward. It's not that he's "more attractive that gravity" but that from the perspective of the water he's now the lowest point around and thus it flows toward him. Like a Endorheic basin it can't flow out to somewhere else. This makes the siphon comment funnier in my opinion as they're suggesting that if then found an even lower point than Beret Guy they could siphons water off of him and to that lower point. Something that the water wouldn't do on its own because of "walls" in his water potential function. 162.158.63.172 23:23, 26 June 2020 (UTC)Max

Do we have a category for comics where Randal is suspected of trolling the explainxkcd community? 108.162.245.132 00:32, 27 June 2020 (UTC)

"All Comics"? 162.158.158.167 00:43, 27 June 2020 (UTC)

"Generating Electricity" is most likely a reference to the https://en.wikipedia.org/wiki/Qattara_Depression_Project

Qatarra makes sense; my first thought was the Salton Sea. It's certainly not a Minecraft reference, since rivers in Minecraft are flat (same altitude as the oceans) & hydroelectric dams do not exist in the game.

(Prior item is unsigned.) Worth a link to https://what-if.xkcd.com/143/ aroujd the subject of siphons? If nothing else, it shows that Randall knows how they work (even if there's confusion over whether BG does, or just has the laws of nature do what he thinks they should do, as per Vacuum Energy). 162.158.155.240 10:57, 27 June 2020 (UTC)

That would be relevant yes. Looking into this I found that the page on what if what if? do no longer work here on explain xkcd...? The link is active but only displays a white page with "No input file specified." --Kynde (talk) 09:56, 1 July 2020 (UTC)


Ordinary siphoning wouldn't work unless MOND or modified inertia dark matter theories are true. 172.68.141.146 18:25, 27 June 2020 (UTC)

No, an ordinary siphon will work fine - it just has to feed past the local maximum & then it'll drain to the sea, just as it would if you put a siphon in a reservoir and fed the siphon's output to a point past the dam. It's pretty clear that BeretGuy's local minimum is not all that deep. Cellocgw (talk) 12:31, 29 June 2020 (UTC)

So, does anyone know what a Colonial Engineer is? I'm unfamiliar with the term. A quick google search just turns up a plastic parts company and a minecraft mod and that's it.172.69.63.169 21:13, 27 June 2020 (UTC)

Isn't it simply engineer from British colony? You know, from the time of British Empire, when that included Egypt, India and lot more ... -- Hkmaly (talk) 22:42, 27 June 2020 (UTC)

Taking a poo must be awful. All that toilet water getting attracted to his butt... DrPumpkinz (talk) 00:07, 28 June 2020 (UTC)

They could also dress him in a molybdenum disulfide membrane to generate electricity. Electricity generated with water, salt and a three-atoms-thick membrane

I just changed the explanation slightly as gravity and personal attraction explains the foot-pooling of water and the not-yet-face-covering for the shower scene (plus hanging off his hand, at least until he raises his arm or brings it to his side to let it flow to is feet as well). Wanted to add in high surface tension (to explain how his feet are sticking outbl of his accumulation of shower-water), but - as you can see - this gets far too wordy. (Surface tension and core-attraction alone would not explain his feet or hand, of course.) 162.158.154.77 10:58, 29 June 2020 (UTC)
