Quantum computing as of now is pretty useless, but try beating QM apart from vaguely reformulating it.

Pure math was a mistake. It's all fun and games until it starts flying in the face of actual fucking logic. Thank God we physicists and engineers are there to clean up after the mess the mathematicians leave behind, filter out all the pure autism like "hurr durr muh set theory" and "hurr durr 1 + 2 + 3 + 4 + ... = -1/12 because 1 - 2 + 3 - 4 + ... = 1/4 and muh Reimann", and turn the remaining bits into useful stuff that actually benefits the world.

You are correct, and I was mistaken because of the finite variance requirement.

Nice trips!

A lot of majors do not require the amount of reading that a math major requires. We are often made fun of, but the same people that make fun of us have no idea and would drop a basic "proof writing" class in days, even if they had the prereqs, if they knew the amount of effort required to complete a math degree.

Consider a 3 dimensional potential in cylindrical coordinates where the potential depends only on r and z, but not theta. This leads to the solutions of Schrodinger's equation being separable into a function of r and z, and a function of theta. The solution for the theta function is exp(i*m*theta) where m=0,+/- 1, +/- 2,...

None of the literature I can find relating to this imposes any meaningful restrictions on m, how am I supposed to interpret this? Are the quantum states really infinitely degenerate?

sure why not

Read the relevant parts from the math textbook ahead of time. Better yet, find lecture videos online (MIT, coursera, udemy, etc) and watch the relevant lectures ahead of time AND the parts from the textbook. THEN do practice problems and try to google your way through them when you get stuck internalizing and understanding the material as you go. Then once you're in class you can go on cruise control and possibly even solved/proved whatever canonical examples they give. At that point you can confirm you know it or something might 'click' that didn't make sense earlier. Do this for each of your math classes. Expecting the professor to teach you things in lectures is generally a bad idea. Usually they don't have enough time in a class to go over the material well and whatever example they solve usually requires creative insights in logic that you may not understand within the 60 seconds they prove the first theorem and transition to the next

Yeah the chrome client fucking sucks though, I can't manage the threads I'm in without using a shit ton of ram.

Safari? No.

/sci/ is a fun board but not seeing the TeX is NoX

What do you call a non-commutative field like quaternions?
What do you call a field that has a conjugate defined like the complex field?
In abstract algebra how do you define a conjugate?
