The Mechanical Universe
The Apple and the Moon. The first authentic steps toward outer space can be traced to a leisurely stroll through an apple orchard. Seeking an explanation for Kepler's laws, Newton discovered that gravity describes the force between any two particles in the universe. From the English countryside to Cape Canaveral and beyond, Newton's universal law of gravity reveals why an apple, but not the moon, falls to the earth. (from themechanicaluniverse.org)
