Welcome


The title says it all: this blog features physics videos found everywhere on the web: animations, demonstrations, lectures, documentaries.
Please go here if you want to suggest other nice physics videos, and here if I mistakingly infringed your copyrights. If you understand French, you'll find a huge selection of physics videos in French in my other blog Vidéos de Physique.

Why the Sky ISN'T Blue

The sky appears blue because of Rayleigh scattering...but why doesn't it appear violet? If the hard disk of a laptop spins in the space station, does the laptop spins? What if you were able to pass the event horizon of a black hole and come back? Is there such a thing as randomness?

 And other questions...
