Physicists and Engineers from Stanford University and NASA have combined efforts to create "a relativity gyroscope experiment...to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity." The Gravity Probe B Experiment uses four gyroscopes orbiting over the earth's poles. The satellites are largely free from disturbance and thus provide "an almost perfect...

It's certainly not impossible to learn about Newton's laws, momentum and other key principles of physics without multimedia learning activities, but it's a bit more fun to have such resources on hand. With funding from The Australian Learning and Teaching Council, Professor Joe Wolfe of The University of New South Wales has created this rather remarkable set of physics teaching resources. Visitors...
