How can we be sure that planet Earth spins on an axis? Léon Foucault knew. His 1851 invention provided science with a simple mechanism for learning about the earth’s rotation. Witness the pendulum in action as it knocks over a peg every 15 minutes.
Out of this World

In 1977 NASA launched Voyager 1 and 2, two probes boldly going where no spacecraft had gone before! After 35 years of zipping through space these ultimate inanimate explorers still work and are still communicating with us! The Voyager program has been a vital source of information used by astronomers in understanding more about our own cosmic back yard.

Understanding Newton’s theories doesn’t have to be a heavy lesson. Marvel at how motion and gravity influence many of the innovations we enjoy today. Test how force affects acceleration at Newton’s Race Track. Get a front row seat for a lesson in angular motion in our gyrochair.
A lot has been discovered about Neptune since its initial sighting in 1846. The Voyager 2 spacecraft, on Aug 25, 1989, did a fly by of this blue celestial giant and sent back some photos and other data that has helped the science community understand more about the last planet on the block. Here are some interesting factoids about Neptune:
Space, the final frontier...
Today at 4:50 pm, space shuttle Discovery will blast off on its final mission into space. On board Discovery are six astronauts, the Permanent Multipurpose Module which will become sort of a storage closet for the space station, and Robonaut 2, the first dextrous humanoid robot to go into space. Robonaut 2 will test his ability to operate in zero gravity and will eventually become an astronaut's helper.
Besides highly publicized science stories of 2010 (Gulf oil spill, Chilean miner rescue, bedbugs, etc.), there were some intriguing and somewhat odd science stories:
1. You think like a worm – The human brain’s center of deep thought is curiously similar to a clump of neurons inside the head of the lowly ragworm. So similar, in fact, that ragworms, which evolved 600 million years ago, probably share a common ancestor with us humans. Hmmm…
