Perhaps the most remarkable scientific woman of the 19th century, Curie opened up the science of radioactivity, discovering two elements and winning two Nobel Prizes (her daughter won a third Nobel). This site was written with material from biographer Naomi Pasachoff.

The Contempory Education Physics Project (CPEP) is a non-profit organization of teachers, educators, and physicists around the world. They have produced a number of excellent materials including award-winning charts and websites for teaching physics and cosmology.

This lavish site contains interactive tutorials, animationsand classroom materials describing the standard model of particle physicsand elementary particles.

Plasma Physics & Fusion; The Universe Adventure

The Contempory Education Physics Project (CPEP) also has produced charts, lesson plmaterials and extensive sites describing both Plasma Physics & Fusion, and an up-to-date cosmological site, The Universe Adventure.

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.
