I saw the bibliography of
- Foundations of p-adic Teichmüller Theory (Shinichi Mochizuki)
and it's four pages long!
>Mochizuki has estimated that it would take a maths graduate student about 10 years to be able to understand his work, and Fesenko believes that it would take even an expert in arithmetic geometry some 500 hours. So far, only four mathematicians say that they have been able to read the entire proof.
http://www.nature.com/news/the-biggest-mystery-in-mathematics-shinichi-mochizuki-and-the-impenetrable-proof-1.18509
While most of the list is doable I think that it would take a lifetime for someone to become familiar with the content of the last part of the list.
Mochizuki is a smart man and I believe his estimate.
Anyone here working on the field?

no that list isn't accurate, you would never need the vast majority of what's in those books

read section 3 'Studying IUT' of https://www.maths.nottingham.ac.uk/personal/ibf/notesoniut.pdf
>>
>>8780565
Good reference.
But still, what are the textbooks from the picture needed to be able to understand what is listed here:
>3.2. Entrances to IUT.
?
Say from
- Functional Analysis (Walter Rudin)
on.
>>
>>8780683
why do you keep caring about the meme list in the picture? it was obviously made by someone who doesn't understand anything about IUT (you'll notice it has essentially 0 intersection with what is listed in the notes by someone who does understand IUT). you certainly don't need to read a book on PDEs, or an entire book on algebraic topology, or an entire book on galois theory... the telltale sign that list is a meme is that p-adic teichmuller theory is listed, which a completely separet story from IUT

just read the papers and look backwards in whatever textbook you want for the algebraic geometry/anabelian geometry/algebraic number theory that you need when you come upon gaps in your knowledge

>Research scientists with a Masters degree or PhD can look forward to earning 30k to 45k a year
>30k to 45k
Why are people with a graduate degree in a STEM field making slightly above minimum wage? I wanted to be a researcher but what the christ?

I'm making a symbolic algebra program. I want it to have:

> different types of variables + rationals
> negative and positive exponents (maybe radicals)
> negative and positive coefficients
> ability to attempt to simplify an equation (reduce amount of unlike variables and terms)
> ability to attempt to solve for (isolate) a variable

What are some relevant abstract algebra concepts or theorems that I can apply to this?

It doesn't sound like you know much about computer algebra or symbolic computation. I'd try looking for a textbook on these topics.

autism is the next step of human evolution.
Autists are needed to develop new technology.
Chads are no longer as useful as they were before

Same reason why theirs more Dyslexics

Because what counts as "autism" is completely subjective, as with all "mental illnesses"

Can anyone begin to fathom how you could create a pocket dimension or simply bend time and space in general? Or do we simply not comprehend or understand what time and space truly are?

>>8779063
give me a lever long enough and I can make a pocket dimension.
>>
>>8779066
How?
>>
>>8779063
you can bend time and space simultaneously by concentrating large amounts of energy (mass) in one spot, according to Einstein

but relativity is all memes and Einstein is a fuckin brainlet
it's far more likely that nobody knows what the fuck they're talking about and experimental evidence is just confounding the truth rather than revealing it

The ability to handle the struggles of life with minimal effort and emotional distress.

It usually boils down to a mindset that enables you to handle unexpected circumstances and knowledge which enables you to handle predictable eventualities.

If you are able to share and teach the above with other people, then you might be perceived as wise.

That just means you will never stop counting, infinity is not a number to be counted. It's like saying you will count to i eventually.

What are our options for creating gravity on orbital stations in the near future?

Spinning shit seems to be the easiest way... If not the only way.

Seems like a bad idea, we should just pump money into Musk's pocket and see what he comes with.

why would it be a bad idea? its the only way (other than linear accelaration) to have perceived gravity on a spacecraft
>>
>>8778406
The best option is obviously to design a spacecraft that has the mass of a planet.

Propulsion might be a bit tough, though.

hi fbi, concetrated nicotine, castore beans, cyanide.

Both cyanide and nicotine are odorless and hard to pick up on autopsies, castore beans are basically cyanide.

Have fun.

>>8778160
If you had to poison, give cancer or give a disease to someone which extends to a period of 6 months to 5 years. Then what would you suggest are the best options? ;)
>>
>>8778178
cyanide and nicotine and castor beans all simulate heart attacks.

Cyanide is great because you can just spray someone in the face with a squirt gun and they are dead instantly.

Dixiefag here. How do we make the South less retarded? The few smart ones are surrounded by hyper-religious nutjobs who deny a lot of science for literally no reason, even in the cities. Our culture seems to be inherently broken, and I'm at a loss on how to fix it.

Yes, but how? It's integral to the culture here. The first thing people will ask you is what church you go to. How did New England stop being a bunch of Puritan fuckers? I haven't seen any research on that.

Why isn't /sqt/ a sticky?

But more importantly, I'm looking for THE authoritative text in "discrete math". Whatever that means. Why don't I hear more talk of it here on /sci/? Proofs are cool, digital logic is fun, etc.

There's rarely a single authoritative text for any field, but Stanley's 2 volumes are certainly classics
>>
>>8773374
Apparently I suck at math.
I have a system with four states, and two state estimators and I'm trying to construct a hidden markov models.
My observations though, are already belief states (probabilities over each state), that is, in the form: [0.1, 0.6, 0.2, 0.1]
What I want to combine is two of those observations, together with a transition matrix (4x4). I can only find HMM literature where the evidence is a single binary observation.
Anyone care to point me in the right direction? What am I missing? Proper book?

Thanks
