Excellent, and very much in the spirit of Griffiths or (the late mathematician) Harold Edwards. Was there an earlier version? I recall watching this more than a year ago. Really inspiring work!
I really enjoyed this video! It was a real delight to listen to the history of Physics and gain a deeper understanding of how the laws of physics were ascertained
@ 10:26 According to Hyperphysics (or better, the Department of Physics and Astronomy at Georgia State University) heat is the transfer of energy (like this: 23:07). Hanging on to this widely accepted definition, concepts like heat flow and heat energy tend to confuse people. It may even lead to a similar error like this: dU = dQ + dW. This is wrong because Q and W are already defined in terms of a change in energy. Thus, it should be: dU = Q + W. @ 13:27 Just switch the i and s irreversibly. @ 44:48 Nowadays, particle physicists want us to believe they can track the traces left by the unobservable Higgs boson. @ 47:54 And I like to add this advice: always be skeptical about what your read and hear in TH-cam-videos too. Simply accepting what you read and hear isn't very scientific.
Perfect. One comment about so-called the "collapse of Schrodinger function". Such talk@vocabulary is...poetry or psychologizing. The wave function exists in an "artificial-mathematical" phase space (as a complex plane). Still, it does predict the outcomes of experiments not with a "particle" but only with a stream (set, bunch) of them - by an analogy: a probabilistic formula predicts the outcome of every lottery: does it mean that Loterry machine "collapses" the probabilistic formula to get winning numbers? A nonsense talk!
Your channel is an absolute gem and criminally underrated. You clearly are a gifted educator and scientist. Wishing you millions of views and subs.
