>research interests started with logic and the theory of surreal numbers, while he was still in high school.[6]
>He is best known for his work, starting with his thesis, on infinity-categories and derived algebraic geometry. Derived algebraic geometry is a way of infusing homotopical methods into algebraic geometry, with two purposes: deeper insight into algebraic geometry (e.g. into intersection theory) and the use of methods of algebraic geometry in stable homotopy theory. The latter area is the topic of Lurie's work on elliptic cohomology. Infinity categories (in the form of Joyal's quasi-categories) are a convenient framework to do homotopy theory in abstract settings. They are the main topic of his book Higher Topos Theory.

I think it looks kinda cool with those specific Math words desu.
Also you can look less autistic in Math if you're into Mathematical Finance, Mathematical Physics and Mathematical Biology desu.
But not gonna lie, "Pure" Math sounds autistic yet it doesn't look like it once you call it "Theoretical Math".
I seriously wonder what's the most and the least autistic science though

Also could be that, but oh boy, they can do lots of good shit like working with our computers, building and studying things, work with big corps, etc.
And Math is quite interesting if you read more of them though, read about the Collatz conjecture for example.

Pathetic.
All non-human species deserve the dignity of a quick and painless extermination. Their continued existence is only cruelty.

Also just wanted to point out that machine learning always looks like this. If you want to just learn some shallow theory behind how to implement a learning algorithm, do not take a machine learning class. Maybe an undergrad one isn't as bad but at the graduate level it's pretty hardcore.

I find this stuff much more interesting than "coding" but finding free material and building your own curriculum is difficult.

Yes, as realistic as it can be while remaining exciting. It isn't completely hard sci-fi, but it is pretty close in many respects. There's more research packed into that show than in most movies.
>>
>>8649988
it does not depict actual evens that have happened or are currently happening, so the short answer is, no.
the longer answer is, we don't have a good enough understanding of how things work in space to be able to tell you if this is realistic, because it depicts technology that doesn't exist yet. so it's really not an answerable question.
it looks more realistic to me than other space combat movies, though. the way the weapons create trails through the ship's interior is kind of cool looking.
>>
I dont understand. Are holes being blown right through the ship? If the ship was full of air then the air rushing out the holes would obliterate those passengers.

How is it fair that a student scores 18 points above the average, with a score in the top 10%, in a class of 120+ students, yet gets their grade curved to a low B, borderline B-. This basically punishes hard work. I could've left questions blank (already did for one) and not have my score change significantly.
Universities are way too subjective in their processes. The same can be said for +/- systems that do nothing, but hurt students competing with grade inflated ivy leaguers and community college students who get positions handed to them for their unearned GPAs.

I go to a private university and I have experienced very little curving at all. I have never had a curve that actually LOWERED my grade, but I did have one professor who had one that gave more points to persons with lower scores. Other than that I've had a couple of flat curves where everybody gets the same amount of points added onto their test score. But in my experience 95% of my exams/classes had no curve at all

Why is American education all so fucking weird?
Why is it hard to just award them a grade based on what score they got?

Depends on the course and the prof and the number of students and the distribution of marks between assessments.

>The crack-prone parts are considered a potentially major threat to rocket safety, the industry officials said, and may require redesign of what are commonly called the Falcon 9’s turbopumps.

To all the intellectual, self proclaimed cryptographers out there: a friend sent me this claiming he deciphered two messages within this puzzle using only Morse Code and Binary. Can anyone verify if this is solvable? If so, what is the message and how might one manage to crack the code?

I actually am planning on doing my thesis in a cryptography-subfield. Spoiler alert but, I hate silly little cryptograms desu, I'm sure it is solvable but I just can't care.
Anyone else ever feel that way about their field? Like everytime someone tries to engage me in talk about cryptograms or sudoku or whatever I just get depressed.

Does /sci/ know any good research regarding migraines?
I've recently developed them and holy fuck, they're awful. Pain, visual changes and confusion. I'm trying to find some research regarding cures, but it really seems like we don't know much about them other than maybe kerogenic diets being helpful.
Any science-backed methods or even anecdotes?

Well, it's caused from pressure. That's why you take aspirin as a blood thinner to help get rid of them.
Almost everyone I have met who complains about them do not drink enough water and are just dehydrated. You might try drinking more water.
>>
>>8649479
headaches comes from usually one of a few conditions:
1: dehydration
2: sexual dissatisfaction
3: meat frugality
4: unactive. : less than 20min a day activity.
So if you want to get better, use a aspirin, start doing yoga, become a vegetarian and do some sort of activity for 20 minutes a day.

I give you Janos Bolyai, Hungarian mathematician
one of the 3 discoverers of Non-Euclidean Geometry (others are Lobachevsky and Gauss)
He was also an incredible swordman, possibly one of the best in the Hungarian army at the time, if not the best
"It is related of him that he was challenged by thirteen officers of his garrison, a thing not unlikely to happen considering how differently he thought from everyone else. He fought them all in succession – making it his only condition that he should be allowed to play on his violin for an interval between meeting each opponent. He disarmed or wounded all his antagonists. It can be easily imagined that a temperament such as his was not one congenial to his military superiors. He was retired in 1833.[4]"

the sun is a nuclear reactor, it's pumping out tons of radiation
Banana trees have big leaves, so they absorb a lot of that radiation.

Does science not rely on certain basic assumptions?
For example, the existence of an external reality, the reliability of induction and, subsequently, that universal laws can be derived from inductive reasoning?
If these are assumed on a common sense basis, then it is somewhat understandable; however, they are not based in reason, as they cannot be deductively proven and most certainly not inductively (as that would entail circular reasoning).
In light of this (if science requires certain assumptions), then how can we hope to argue against the acceptance of assumptions that lead to contradictions of scientific fact?
How are we to discern which assumptions are permitted and which are not?
Doesn't it just boil down to intuitive, but ultimately arbitrary, preference?

>Doesn't it just boil down to intuitive, but ultimately arbitrary, preference?
Sort of. Usually everyone agrees on some basic things like using your eyes to see or trusting in things that have 95% likelihood.
With those basic agreements, everything else can continue to happen.
People who reject those basic things are pretty dumb in my opinion.

>People who reject those basic things are pretty dumb in my opinion
Yeah, that, or continental philosophers, a.k.a. people who won't take common sense for an answer, yet seem to have no trouble sneaking fantastical metaphysical baggage into their theories.
I'm OP, btw.
>>
>>8649441
if an assumption leads to a contradiction of scientific fact then you just run with the theory until it leads to a clear, unexplainable contradiction with observable results.
