The career of a young theoretical physicist consists of treating the harmonic oscillator in ever-increasing levels of abstraction.

Has to be the best physics tutorial I've seen on youtube and it's way better than most profs do in class.

@science_caro

this is an old video but brooo you're saving my life I have a quantum mechanics midterm and this makes so much sense yaaay

@sphericalchicken

The commutator of two operators is defined [A,B] = AB - BA, so -[A,B] = [B,A], so whether you get [x,p] or [p,x] with a negative somewhere else doesn't really change the result, just the way it's expressed.

@lizXP1

This is by far, one if the best quantum mechanics explanations I have come across on youtube

@aronhegedus

This whole video is very professionally done, I love how neat your writing is, and how clearly you relay the information. Thank you!

@Gismho

Excellent series!!! Thank you Prof. Carlson. Extremely well explained. I'm glued to this series!!!!

@josephhamilton6419

Excellent!! How logical and clear this lecture is. Appreciate it a lot!

@fornasm

WOW, I had already done this, but here it is better done and clearer. 1/2 QFT is in this lesson. well done thanks!!

@sibusisiweradebe7842

I have a quantum mechanics test tomorrow and you just saved my life

@Steven22453

You're a lifesaver, that's all I have to say.

@buddydiamond8736

I really wish you were my teacher and not who I have now... this was a question on the test and I was completely lost... anyways, I'm very grateful this video exists.

@JohnVKaravitis

Superb quantum mechanics videos. Your hard work is appreciated.

@dzarren

At 32:18 you say that the denominator is equal to one, so we can ignore it.
You say its because sqrt(n+1) where n is zero so the denominator is 1.

But actually it's because the denominator would be sqrt(1!) from the formula for PSI_ n.

@ajmeriamreenchowdhury933

This tutorial was incredibly good!!!

@luisbreva6122

Do conmutators have something to do with Poisson brackets?

@saramounata

Thank you for existing!

@koenth2359

18:40. 'Now you notice I have an A+ here and an A+ here', that sounds so smug!

@jasonhe6947

Thank you. It's really a pretty good explanation. It helps me figure out lots of questions.

@SWiSHRoyal

Thanks! Saved my exam.
