HELLO Amit sir, if you are reading this I really want to thank you. Such an eclectic piece of information on duality of light (wave or object). This is just pure pursuit of knowledge. Physics had been my fav subject but never made any career out of it. But it feels so good to learn , reconnect with the fundamentals with such crystal clear understanding of the concepts. I really liked how you skipped the history of the quatum mechanism saving it for latter. Which generally would be taught first just because it is n the curriculum. I wish i was your student. 🙂

Dear professor, One can show using the Lagrangian formulation that the electron’s momentum (and also perhaps photon’s if one has the appropriate setup) is going to be an ambiguous quantity…..

[@whiteholeeducationcenter]

Thank you sir from Pakistan

[@scottychen2397]

Hold on, You say Newton’s laws can be DERIVED from the principle of least action….. It can certainly be shown to be EQUIVALENT. Obviously the lagrangian -action formulation is a different interpretation and more general in a sense…. I wouldn’t say its more fundamental - and this is whats being implied when you say ‘derived from’ Because you truly do draw in a new interpretation. The equivalence is a pure mathematical one with no philosophy required

[@elguapo3436]

With some retreat, i doubt very much that the teaching/learning of quantum physics should benefit from oversimplified analogies, which can be useful for demystifying... but instead one should preserve the spirit of this highly refined scientific substance with its intrinsic learning curve, definitely beneficial especially when touching on the conceptual aspects of the quantum paradigm and its mathematical framework. I think that one of the most refined literature references on the subject are the three volumes written by the french physicist and nobel prize winner Claude Cohen Tannoudji, Quantum Mechanics I,II & III, truly a delight.

Dear Professor, There are other so called wave-functions Representing the wavering of perhaps quantities or also other things that are tangentially related to radiation and so forth…. Pure mathematically, this is nothing more than a sinosoidal function or perhaps a finite or countably infinite sum of these. In your course you choose the basic varieties. This particular wave function of the basic variety, Is a wave of the quantum particles (which truly JUST means small-scale - nothing on the order of BULLSHIT) ONTOLOGICAL STATUS. WHETHER ITS THERE OR NOT the associate probability density is of metaphysically exactly the same nature. This is not a question of association, or anything other than exact metaphysical claim. If youre doing ‘YOURE OWN THING’ then you should be specifically clear what youre trying to do. This so called de-broglie wave you are attempting to teach is a specifically ONTOLOGICAL measure. So no, thats not correct and you are not in a position to be considering anything truly basic a degrading way. I CANNOT RECOMMEND THIS PARTICULAR TEACHER FOR THE DEEP MISUNDERSTANDING OF THE WAVE’s NATURE: one of ambiguity, not necessarily confusion. I RECOMMEND ED WITTEN, LEONARD SUSSKIND OR PERHAPS AN EXCELLENT VIDEO TAUGHT IN HINDI WITH A MORE NATURALLY INDIAN FEEL TO IT. Or something more correct at least

[@scottychen2397]

@1:28:55 Why is he having an attitude about not using the theoretical musculature that is QM in the case of photons? This looks like empirical knowledge….. that’s strange!
