Interesting Facts About Physics

1. A light year is 5,865,696,000,000 miles or about 9,460,800,000,000 kilometers.

2. The angle at which light reflects off of water to create a rainbow is 42 degrees.

4. The E. Coli bacterium propels itself with a 'motor' only one-millionth of an inch in diameter, a thousand times smaller than the tiniest motors built to date by man. The rotation of the bacterial motor comes from a current of protons. The efficiency of the motor approaches 100 per cent.
