Don't worry nobody understands quantum the first time they see it.

I only managed to solve for the Hamiltonian and the raising operators b/c they looked somewhat like linear. Pray that your classes in matrix algebra help you out (b/c they will).

Oh man this had me cracking up. This shit is so insane. All these words flowing around here that I have heard before but have no idea where. It just sounds crazy! Good luck to you mate.

Wait... Is this the same Quantum Physics/Mechanics that most engineers take after electricity/magnetism?

I have to take it next semester. Damnit.

heh, my second semester quantum was supposed to be easier than first semester... more math [operator stuff instead of calculus], but similar material (QHM, ladder operators, "supersymmetric method," etc.; basically a ton of commutators)

but I didn't put in enough time and got owned... managed to escape with a B though, heh.

I give up on physics

Too much non-math

Right now, you know you don't understand the solutions.
Therefore, just cover the page. Eventually, you will both understand and not understand.
That might be the best you can possibly do.

can someone who knows this stuff tell me if my joke works? If it doesn't, can you try to make it work? There's a good joke in there somewhere

I am a high school student who thought I was intelligent. Welp, time to practice my drawing skills.

He IS supposed to be able to understand how to solve certain situations. Please differentiate the model from the actual thing.

Thanks to the "subscribed threads" feature, I came back here!
I'm curious, how did it go? Did you pass?
Best wished with your QM studies.

I read the first two pages..and now my head hurts. This is why I majored in Business.

Ha! I have an Advanced Quantum Mechanics 3rd year exam tomorrow and I accidentally found this after blowing up and typing "FUCK QUANTUM MECHANICS" into google... Lifted my spirits a little after a day of fucking dreadful revision of bullshit maths.

How did it all go in the end? You said "first try" in your blog, are you allowed multiple attempts? We get 1 chance to get a proper mark, if we fail then you can only ever get a grade of 40%(a bag of shit in our system!) after that. I have to pass this module as well or I can't advance onto 4th year as it is a core topic

My current plan is to memorise the answers to the last 3 years worth of papers within the next hour before I go to bed and then hope to god that I don't have to go thru this all again for a resit in summer...

FUCK QUANTUM MECHANICS!

I took quantum mech 1 in fall 2012 semester (US university; my uni has a quantum I and quantum II) and I got super lucky as our grade was pretty much just problem sets and even take home tests.

I literally understood none of it but scrounged answers via googling/textbook best I could, such as the problems for wave functions/reflection+transmission coefficients for the delta potentials/double delta potentials/whatever potential, etc etc.

good thing I wasn't a physics major that had to actually learn the stuff properly. I had it as a tech elective.

quantum tricked you into thinking it would be fun. Day 1 and 2 was stuff about Stern Gerlach experiment, stuff that sounds fun, then jk do a million proofs of uncertainties/wave functions/harmonic oscillators using baker-hausdorff formula/virial theorem, etc etc.

edit: <YO|LO> bro-ket.

looooooooool this is what happens when physicists meet mathematical physics >________>;;;

boom goes the dynamite. Oh shit, subspaces and self-adjoint operators, get out quickly~
