OK, not the physics of how the website works (although that would be interesting too) but “what kind of interesting physics videos can I find on YouTube?” I was thinking about this as I was trying to find videso about motion in a non-point-mass potential and kept finding things about how to paint your fingernails with a galaxy design. Really.
But there are gems out there, and surely what I could turn up in half an hour only scratches the surface. Of course there are course videos from universities and the like. Check out the first-year course taught by Walter Lewin from MIT, and Leonard Susskind’s Modern Physics course at Stanford. There are lots of videos of galaxy collisions and some scary ones about MRI safety.
There are several YouTube channels which have good stuff: there’s Minute Physics, the University of Nottingham has Sixty Symbols, “videos about the symbols of physics and astronomy”, and the American Physical Society has a Physics Central channel.
And then a few random ones that I found amusing:
Space telescope physics (not for cat lovers)
Ruben’s Tube (most of us should not try this at home)
Spitzer Space Telescope — the Musical
