The Indian Institute of Technology Madras has some online collections of lectures. Among them, a Quantum Physics course imparted by Prof. V. Balakrishnan. You can see the first lecture below, devoted to an introduction to the conceptual underpinnings of quantum mechanics and, more specifically, Heisenberg’s principle. Prof. Balakrishnan does a remarkable job at explaining these horny issues, avoiding common pitfalls; and, as the students’ questions make him wax philosophical, he shows a very refreshing honesty in not trying to sell the theory as the end of the path, avoiding the “shut up and calculate” stance that was so common during the second half of the past century (and which i still suffered during my undergraduate and graduate years). The exposition doesn’t use any advanced mathematics and keeps at a conceptual level, and i think it should be understandable by anyone with a very modest background (perhaps some acquaintance with classical mechanics will help at some point, but it’s not a requirement to enjoy the lecture).
There’re are thirty more lectures in the course, all of them available for your learning pleasure. Although i haven’t had the time to watch them all, if Prof. Balakrishnan keeps their quality as high as in the first installment, i’m pretty sure they’ll make up for many hours of fun.
And, if you feel like learning classical physics, i’ve got good news for you too: there’s also a series by Balakrishnan on Classical Physics! Here’s the first lecture:
