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...

Produced by the University of Missouri - St. Louis, this website is an educational "resource for solving low and high speed constant acceleration problems." Physics students can find quantitative tools to handle time dilation, relativist acceleration, and curved space-time. Containing networks of numerous concepts dealing with physics, chemistry, and math, the site helps students understand how...
