This is a video by Professor of Physics Emeritus, Walter Lewin of MIT. Please don't go to another thread . It is a very nice and enjoyable 40 minute video on a few physics topics (such as why sky is blue). Importantly, it shows that there are teachers that can really engage and get one interested in the topic as Prof. Lewin does. If all physics classes were taught like this, we would not need exams because we are all so interested that we learn the topic as presented! Really fun video and I hope you take the time to watch it.
Here is the description that goes with the video which has some 600,000 views!
