Johannes KeplerDied 15 Nov 1630 at age 58 (born 27 Dec 1571). German astronomer who formulated three major laws of planetary motion which enabled Isaac Newton to devise the law of gravitation. Working from the carefully measured positions of the planets recorded by Tycho Brahe, Kepler mathematically deduced three relationships from the data: (1) the planets move in elliptical orbits with the Sun at one focus; (2) the radius vector sweeps out equal areas in equal times; and (3) for two planets the squares of their periods are proportional to the cubes of their mean distances from the sun. Kepler suggested that the tides were caused by the attraction of the moon. He believed that the universe was governed by mathematical rules, but recognized the importance of experimental verification.« |
Double Martini
A businessman enters a tavern, sits down at the bar, and orders a double martini on the rocks.
After he finishes the drink, he peeks inside his shirt pocket, then orders the bartender to prepare another double martini.
After he finishes that it, he again peeks inside his shirt pocket and orders the bartender to bring another double martini. The bartender says, "Look, buddy, I'll bring ya' martinis all night long - but you gotta tell me why you look inside your shirt pocket before you order a refill."
The customer replies, "I'm peeking at a photo of my wife.
When she starts to look good, I know it's time to go home."
