You have done great service to the small community of Physics Students who wonder How & where from was so much Linear Algebra & Operator theory was forced upon humanity in the Historical development, esp when we study QMech in the Modern way from J J Sakurai and the like... Thx a tonne!

[@vtrandal]

Your work explaining the historical development of quantum mechanical models if fantastic and greatly appreciated. Thank you!

[@ihmejakki2731]

I just come across your videos again and again and I can't understand how you're not a bigger name on youtube. Super good stuff!

Finally the wait is over!

I am totally in love with your work and content on youtube. You are providing something that many books fail to deliver, developing the subject in a chronological order. I just wanted to ask you that, will you be covering relativistic quantum mechanics and dirac equation anytime soon in future? eagerly waiting for your upcoming videos.
