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.

Written in the Sky (aurora borealis)

The northern lights, or aurora borealis, have fascinated people for generations. Some believe these ghostly lights in the night sky are the souls of the dead sending messages to the living. For space plasma physicist Jim Wild, the messages sent by northern lights are vital. They are messages from the sun and we need to listen carefully.
