Love your videos! I'm not a physicist, but a physical chemist, and I come back to your videos often for review on EM & QM!

Your lecture notes together with Griffiths have collaboratively cleared my perspective on Angular-Momentum.. For the past two-three weeks, I was stuck on the topic of Quantum Angular Momentum.. While following Griffiths I found some of the relations and assumptions are falling straight out of the sky.. Your video has just come in time.. Thank you very much.. Keep on Going.. It would be of immense help if you just continue with the Quantum Theory.. thank you once again..

For future reference, you might like Brian P. Anderson's book "A Field Guide to Quantum Mechanics." It is relatively short (130 pgs.), but extremely dense. It skips over flowery language and puts down everything in an almost bullet point like fashion, provides very good explanations and computational guides to fundamentally important concepts (including Clebsch-Gordan coefficients, Bloch sphere dynamics and Rabi oscillations).

I am a physic student and it was so helpful. Now i can understand it physics rather than memorize it.❤❤

Can we calculate and model in 3D space a physical process called a uranium or plutonium nuclear explosion?

Are you going to derive the eigenvalues of the L^2- and Lz-operators in the next video?

@fufaev-alexander Жыл бұрын

I can do this. On my website you can also find the derivation: en.universaldenker.org/lessons/1161

FOR THE QHO A LADDER OPERATOR WAS KIND OF LOGICAL TO INTRODUCE. BUT HERE THE LADDER OPERATOR JUST FALLS OUT OF THE BLUE SKY, IMHO. By the way, the same is true for the authors Griffiths & Schroeter in their book.

Wo sind deine deutschen Videos?

In einer Playliste auf diesem Kanal: kzfaq.info/get/bejne/bceZjcxlutPKY4U.html Die alten Videos (aber nicht alle) gibt es auf einem anderen Kanal: www.youtube.com/@universaldenker_physik (leider sind Maxwell-Gleichungen, Schrödinger und Differentialgleichungen leider nicht mehr verfügbar. Ein Unfall gewesen.^^)
