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.

Perhaps even more amazing is the fact that you can easily 'grow' your own piezoelectric crystals overnight using just a couple of common ingredients.
