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!
I appreciate that!
I am a physic student and it was so helpful.
Now i can understand it physics rather than memorize it.❤❤
Amazingly concise and well-explained; thank you!
i'm just recently introduced to your channel. this new subscriber is a fan of your method of explaining, and especially your visualization
keep up the good work!
Thank you very much.
you really helped me and i will check other videos
NIce and concise. Thank you!
Perfectly explained
Many thanks sir.
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).
@@andrewdirr824 thank you very much for the suggestion
Thanks Sir. Could you please make a video about the dirac equation? Would be nice. Keep up the good work
Thank you so much sir for thiss !! U are a savior ❤
Thank your for your feedback! :)
Brilliant explanation!
Thank you Michael!
good video bro, easy to understand.
Thanks!!!
This is best way to understand the angular momentum
thank you very much!
Your Video help me understand quantum a lot hope you can update more quantum knowledge video
Thank you, I will
Are you going to derive the eigenvalues of the L^2- and Lz-operators in the next video?
I can do this. On my website you can also find the derivation:

🙏
Can we calculate and model in 3D space a physical process called a uranium or plutonium nuclear explosion?
Where are the rest of your videos, did I just jump dimensions?
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?

(leider sind Maxwell-Gleichungen, Schrödinger und Differentialgleichungen leider nicht mehr verfügbar. Ein Unfall gewesen.^^)
