emergencyfood, in Asking mathematicians about their proofs

Srinivasa Ramanujan was an Indian mathematician who worked on number theory, infinite series and analysis. He said that he would have dreams of drops of blood (a symbol of his village deity, the goddess Namagiri Thayar), followed by complex mathematical equations. Even with the help of his formally-trained friend GH Hardy, he was only able to prove a small fraction of his insights.

Gregori Perelman is a Russian mathematician best known for solving the Poincare conjecture. He posted his results on arXiv in 2002-03, but never published them in a journal and never accepted any prize or money. He has expressed dismay over the lack of ethics in research.

Anon is a /sci/ user who in 2011 proved the current lower bound of a superpermutation for any size greater than 2 (the Haruhi Problem). Their proof has been archived for posterity, but we don’t know anything more about them.

glad_cat,

4chan wins again!

6daemonbag,

Incredible read, thanks for elaborating!

octoperson, in Asking mathematicians about their proofs

Shinichi Mochizuki (the abc conjecture guy): elaborates further. You understand less.

Well given that I remember my professors barely knew how to code when they were the ones teaching us, I’m never surprised computational papers are like this…

That’s what you get when people never learn alternatives to MacOS or Windows

Is there a site that does a variety of energy comparisons

underisk, in I call it spooky science

Einstein called quantum entanglement “spooky action at a distance” so you’re in good company.

WarmSoda,

That’s the joke, yes.

Doll_Tow_Jet-ski, in I call it spooky science

Interestingly, when Newton published his Universal Gravitation theory, it was considered as spooky as quantum physics is nowadays. It broke away with the Mechanical philosophy of the day that saw the natural world as a series of direct cause-effect interactions. Even Newton disliked the implications of UG and tried to make them for, unsuccessfully, into Mechanical philosophy.

nothacking, in Super easy, barely an inconvenience

Dunning Kruger is very real.

I just heard about the Dunning Kruger Effect, but I feel like I understand it REALLY well.

Underestimating complexity is tight!

I have no affiliation to them, just a reverse image search. This looks to be SEVERAL popular posts on Reddit, but somehow I’d never seen it!

AmbientChaos,

Thank you for sharing this. I saw this post and didn’t even see the meme because the art is too good!

4am, in How many?

Did they read “a mole” and misinterpret it as “molecule” when writing the headline?

porkins, in How many?

That took me too long.

critical, in How many?

At least twice as much!

thepianistfroggollum, in How many?

Alright, I know where they went wrong here. There are more hydrogen atoms in a glass of water than stars in the universe.

There are about 1.58 x 10^25 hydrogen molecules in 8oz of water, and there are an estimated 10^22 - 10^24 stars in the universe.

Edit: super script markdown wasn’t working

Is it wrong? I’ll do some complex math, so feel free to ask follow up questions.

Hydrogen atoms in one molecule of water: 2

Stars in the entire solar system: 1

2 is larger than 1 [citation needed]

thepianistfroggollum,

I’m sorry for your poor reading comprehension.

Is there a confidently incorrect community yet?

Kayel, in How many?

Ignoring the joke.

A metric cup is 250 ml.

250 ml = 250 g (the density of water is intentionally 1.000 g / ml)

Water ~= 18 g/mol ( H 1.008 g/mol, O 16.something g/mol)

250 g / 18 g/mol = 13.8 mol

13.8 mol * 6 * 10^23 atoms/mol = 8.33 * 10^24 molecules of water

And there are two atoms of H in one molecule of water, so 1.66*10^25 atoms of hydrogen in a glass of water.

That’s a lot

EmoDuck,

The craziness thing about all of this is that there is actually such a thing as “a metric cup”
