Do you want to solve every physics problem? Try my book!

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!

[rajanalexander]

Amazingly concise and well-explained; thank you!

[GeoffryGifari]

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

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..

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

[un_tangle]

Thank you so much sir for thiss !! U are a savior ❤

[AbdelaliBerrahhal-zkrt]

This is best way to understand the angular momentum

[ekvuyyv]

Thanks Sir. Could you please make a video about the dirac equation? Would be nice. Keep up the good work

[dmhenix]

Your Video help me understand quantum a lot hope you can update more quantum knowledge video

[Joker-ohlb]

Where are the rest of your videos, did I just jump dimensions?

[ko-prometheus]

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

[jacobvandijk]

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

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.
