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.

Cloud Chamber

Subatomic particles such as cosmic ray muons, alpha particles, and high energy electrons are striking our bodies all the time. In the cloud chamber, these particles ionize air molecules, creating delicate cloud trails by condensing supersaturated alcohol vapor. This is similar to the way condensation trails are formed in the sky behind airplanes. This is about as close as you'll ever get to seeing subatomic particles with your own eyes...
