>LARP as ascetic, friendless, super-disciplined hermit whose life is wholly dedicated to mathematics.MEANWHILE:>He had a son with his landlady during his time in Nancy>With his wife Mireille Dufour, he had three children: Johanna (born 1959), Alexander (born 1961), and Mathieu (born 1965)>He also had one child with Justine Skalba, with whom he lived in a commune in the early 1970sFrom my, chronically online 4chan anon perspective it seems like there is clearly something not right about his propaganda.inb4: He only became monk when he was elderly creep.No, it was said that he was ascetic, friendless, super-disciplined even when he was studying as undergraduate

>>16157949I remember that I read somewhere that during his student days, his professor asked one of his students to go out with grothendieck, because he was worried that the only grothendieck was doing was studying math in his basement.
Thinking people smarter than you always have to be some kind of aspie is a coping mechanism, anon

>>16159554Yeah I (am pre premedschool) think that a lot of jt is memorisation, but talking to doctors and psychiatrists has made me realise that you do also need tricks, you need to know maybe less like every single disease word for word (and there are databases they can search symptoms on) and more how to navigate a conversation and ask questions ans interpretA child would also need to learn how to communicate is what I'm saying

>>16159579But that's not what people in med school usually complain about, most of the time you'll hear them saying they have to study a lot and have barely any free time. But learning how to deal with people isn't something you hit the books for nor something you can do by yourself. So again it seems like if someone started early then med school would be much easier. The difficult part would be getting many hours in the hospital to train that human side, but that makes the job demanding, not school difficult.
>>16159601There are lots of mnemonics to help you learn ans it can be grouped together. Also working in hospitalsA good thing to do is to remember than eventually it will all be daily stuff you'll be used to. Something that I've heard people complain about is long hospital working hoursIt would be good to teach kids because they have more neuroplasticity at that age, but during the brain formation it would probably still be good to socialise them, teach other things, and make sure they get a lot of sun and fresh air :)Those are just my opinions ans I don't study nearly enough, but I am getting the info I think. I'm also > 25 yoIt might also be cruel to do that to a child. The same thing with actors. You can't know theybwill want to do that up until the proper age - it's bad to live precariously through your offspring. It could traumatise them or leave them stunted!
Is there a scientific explanation for why these two trends were so tightly related before the early/mid 1970s and then because completely unlinked subsequently?

Theres only about 30% of additional wealth that can be transfered to the working class.By that i mean, if the rich wnt without any profit, if all investment ceased, and if government shady projects like funding for science or paying interest on debt stopped, workers could get 30% of the wealth sent to them. Which would be like a 50% raise in real terms of their wages.Regarding the investments, they might still get done as long as workers agree to allocate half if their raise money into investments, which they would own, but its important that they get done. Their own jobs depend on these electrical plants being built.
>>16158151>America was commie before ReaganImagine being this brain broken. People that hate Reagan aren't commies. They just want to make America great again by tearing out all the bullshit he pushed for and returning to a time when our economy actually worked for Americans instead of Republican donors.
>>16156142The real reason: skill outsourcing. Basically, computerization took many responsibilities away from workers. Before affordable computers being a skilled, reliable accountant was something much harder. Much more was done by hand. Once hardware and software innovations made many accounting skills practically obsolete, per worker productivity did "rise", but that wasn't because the accountants became more efficient. On the contrary, they became more replaceable, driving their real wages stagnant.

If I know these two quantities:[math] \langle \alpha |\hat H| \alpha \rangle[/math][math] \langle \beta |\hat H| \alpha \rangle[/math]Is it possible to calculate:[math] \langle \beta |\hat H| \beta \rangle[/math]? If so, how? [math] \alpha [/math] and [math] \beta [/math] are wavefunctions and [math]\hat H[/math] is a regular Hamiltonian.
>>16159338no, think about H as a matrix and these quantities as matrix elements, knowing some doesnt tell you what the others are. To a point, because if H is Hermitian then there must be some relations among the matrix elements, and knowing enough might tell you what the others are

The official arbiter of scientific misinformation (appointed by the government controlled by the official Party of Science), Nina Jankowicz, says that the government must crack down on misinformation like sending pictures of empty egg cartons to women. That is “meant to remind [women] that [their] fertility is waning.” And that is “gendered misinformation.”So there you have it. Couldn’t be any more official. Science now believes women stay at the same level of fertility throughout their lives.Science is retarded and clownishly evil. Smash science. Kill science.
>>16157117Yeah all it takes is the total eradication of your current state, then the implementation of [your] state, then the same thing again once [your] state begins misbehaving as well.

>>16146616i always thought the window for males was larger than for females, especially if you took care of yourself but i've been getting conflicting messages about it. I was planning to start getting kids around late 20's, as many as my income will alow by that point, but if i'm likely to become infertile/have retarded kids by 35 then all bets are off.
>>16146472>When your """intellectual""" takes are second order /pol/ barfIf there is any failing in the West is the overabundance of these impressionable, doom-gloom idiots.
>>16159432Think about it for a second anonThe female has the plumbing, and the eggs are made during birth of the women. The plumbing is rigged up and is operational by sometime in early puberty, where a ovary(egg) is spent for each mensturation. That has 2 consequences:1. Only about 500 eggs is spent before menopause kicks in2. The eggs age, and there is no selection mechanism to kick out less competitive eggs Meanwhile for Sperm, you instead have a mechanism to make sperm. And there is a selection via sperm health since its technically a race.The fittest % has a chance of winning the race, but overall reproductive health is still a factor. This DO make the window larger, but it needs to be reality checked: The point of test tube babies IS that you get to have a selection of the ovary. The sperm race might offset a little, but its still fucked. The process is also cumulative, meaning age of father vs age of mother. And since marrying a older man is more likely in most cultures, it is what it is.

I'm not a biologist so I don't understand the intricacies of DNA(and I doubt the people who spam this constantly do either) but what does this mean;That only blacks have archaic admixture or that theirs is a mystery? Because if it's just the latter that means the spammers are equal amounts of sub-human as well.

>>16159568Technically also correct, but when it's something as big as saying africans don't act like other humans then when that is finally validated I think it's fair to say /pol/ was right.

What's that whore talking about? Python is the easiest shit to install across all OS. In fact these days, you just install anaconda and run Jupyter, which works out of the box. Or is she doing "data science" by writing in pythons idle?
>>16159558Python/Jupyter simply for the flexibility and prevalence.I prefer Mathematica, in all honesty. The front end features slow it down, but it's got some terrifically optimized features for handling large data sets and symbolic functions, and its ability to creature figures and animations puts Python to shame. However, if you want a legit copy of it it costs a small fortune and cracks of it are getting less and less reliable.

Hear me out: if th univers is somehow cyclical, then any state that was previously there will happen again eventually, including us sitting here having this conversation. now since i dont feel the time between the alive states because i cant feel non existance, that means when i die, i will just wake up again in my next life.very comforting thought, IF the universe is cyclical.

Basically
What happened to them? Did they publish their proof?
>>16094169>>16108379>>16148008if you go through the list at cut-the-knot, it really does seem like their proof is different from all of them. The closest is #100, which has the same “waffle cone” look but #100 happens inside the triangle, and the students’ new proof happens outside the triangle. I think #100 is nicer, and I think (but don’t know) that they got the idea from looking at #100. But it does seem to be different from the things on the list.

I was wondering what the minimum temperature a naked human being with no shelter could survive imperpetuity and this gent thinks its 17c( 62f). This sounds a little too warm, no? I think it should be closer to like 10 degrees c( 50f). What you make of it?

>>16159245Look like a cool(lol) people. They're tribal dress looks like it belongs in a indie dark aesthetic music video. Love it. Thanks for the mention.Now, from a comment thread on reddit someone said that the Westerners observed that they had semi permanent fires going continuously, that certainly would have helped in such cold temps with little clothing. My question is how low in temperature with no assistance via clothing, shelter, campfires or otherwise could a human survive continuously...maybe 17c is correct...

>>16159402>Well if I prioritize measure theory I'd have to miss half of another, mandatory classOK looks like you're missing half of another, mandatory class then.
>>16159407I'm too far into my degree to do that.I have self-studied some measure theory but it would have been nice to take the class.
>>16159450What's so great about measure theory?Especially compared to abstract algebra
>>16159457If you do anything at all that uses integrals anywhere, it's essential to understand. Measure theory is the foundation for the modern theory of integration and absolutely necessary for understanding topics like probability, Fourier analysis, linear operator theory, PDE's/ODE's, Bayesian statistics (you can kind of get away with Riemann integrals for most frequentist/ML methods, but once you've involved Bayesian priors measure theory becomes basically mandatory if things aren't linear and Gaussian), convex analysis, etc.
>>16159494Is it enough to self study the basics like lebesgue integration and similar basic concepts?Or do you really need an in-depth class?
