the answer will most likely be Heisenberg's uncertainty principle

This is me with AP physics C

It seems stuff that the other kids just intrinsically know like what angles are equal and when to use sine or cosine, I actually have to grind out and use a bunch of tertiary sources to teach me

You know, as long as you don't check up on your grade, it can assume neither a passing nor failing state. Best just ignore the homework, imo.

It's just Griffiths, you can look it up online, it's a pretty popular book. The one I was doing you had to normalize the wave function, find the associated potential energy function, calculate the expectation of momentum and position, and check that the wave function followed the Heisenberg Uncertainty Principle.

Hell if I know. I wish I could say it was just me being verbose but according to the professor it's actually happening for most people in the class. :/

EDIT - Not like it matters, I like writing proofs, but still. <_<

I remember showing up to my first General Relativity midterm exam and seeing it was only 4 questions. Then I left 15 minutes after the exam formally ended with two of them blank.

Still got a C-. Changed majors the next week.

What are some of the things you are proving though?

Well I can't speak for the current homework assignment since that's not due until Wednesday (so that could definitely be me). We're mostly looking at various relations and proving whether they're equivalence relations, and if not which properties they do/don't satisfy. There was also one on partial order in there, and another one circular relations. Might be others that I forgot.

The previous one we haven't gotten back but everyone's stuff looked pretty long. I don't have the assignment in front of me but basically it was proving various properties of sets. Like (A union B) intersect C = (A union C) intersect (A union B). Stuff like that (that specific example might not be a property but it illustrates it essentially). There was also some stuff on fuzzy and crisp sets, and some quick set operation stuff (like you might be given a universe of discourse, a few sets, and you might find various unions, intersects, complements, stuff like that), though that didn't really take too long; same for a couple of problems in finding which sets were equivalent.

The previous one before that was proofs involving various properties of numbers. I recall proving:

- All rational numbers have a prime factorization, and that it's unique
- That between any two rational numbers that there's an irrational, and an infinite number of them
- We *might* have had to prove the opposite: between any two irrationals there's a rational, but I could be wrong
- That "rounding" operations don't necessarily work with the distributive property (I didn't actually go into a full-blown proof on this: I was tempted but it quickly became a headache in my scratch work so I just went with a quick counterexample)

It's easy stuff - just takes some time I guess.

I just don't know how you are taking ~3 pages a proof at that level. But if your prof is fine with it, then it's whatever.

imma probably minor in physics. I can use it to satisfy a few of my cs requirements but i don't necessarily need it. But I love physics and I think there's a dope overlap between cs and physics. think quantum computing

yeah its an intro course but the algebra in these problems is not nice at all. I had to do integration by parts like 7 times in one question lmao

2e? that book wasn't very helpful imo. I dunno why it was so popular, I had to use it too. I learned more looking up videos of lectures online than using that book lol

I got my degree in physics and that's pretty much standard with Griffiths.

We would always get a week to finish a homework set. Would be a few questions and I don't think I was ever able to finish in just 1 or 2 sittings. Though most people would just wait till the TA had office hours in the physics study room and they'd all work together.
