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.

How to Weigh the Earth

This video demonstrates how to determine the mass of the earth using some very simple equipment and a powerful mathematical expression.

The video includes a discussion of Newton's universal law of gravitation and Cavendish's famous experiment that led to the determination of "G" the universal gravitational constant.
