This is an interactive website exploring the history, people, and landscape of CERN, home of the world's largest particle accelerator. The site examines the scientific and cultural ideas that have emerged from the...

This site from HyperPhysics provides a description of Pascal's Principle, which explains how pressure is transmitted in an enclosed fluid. Drawings and sample calculations are provided. Examples illustrating the...

This video demonstrates conservation of angular momentum. When a person on a rotatable platform (initially at rest) tilts the axis of a rotating bicycle wheel, conservation of angular momentum results in spinning of the...

This video demonstrates the conservation of angular momentum. In the experiment, as weights are pulled closer to the axis of rotation, a person on a rotating platform will spin faster due to a change in the moment of...
