This site contains interactive tutorials, quicktime movies and classroom materials describing the standard model of particle physics, fundamental forces, experimental particle physics research, radioactive decay, and a history of atomic physics. There is also a tutorial on Fusion available.

To show the principles of magnetically confined fusion, the site has a virtual fusion reactor, called the 'Virtual Tokamak.' Try the Plasma Drift Applet to get a feel for how magnetic fields are used to contain a plasma in a tokamak. Exercises can be used with the Virtual Tokamak to unearth the underlying fusion physics.

Hands on CERN is a project to make modern scientific information from high energy particle collisions at CERN available to scientists, students and teachers very soon after they have occurred. Explore the world of particles, the building blocks of nature- quarks and leptons. Learn about high-tech experiments, accelerators and detectors.
