Parking Spot

A guy was driving down the street in a sweat because he had an important meeting and couldn't find a parking spot.

Looking up to heaven, he said: "Lord, take pity on me. If you find me a parking place I will go to mass every Sunday for the rest of me life and give up me whiskey!"

Miraculously, a parking spot suddenly appeared.

The guy looked up again and said: "Never mind, I found one."

Pierre Mechain

Died 20 Sep 1804 at age 60 (born 16 Aug 1744).Pierre (-François-André) Méchain was a French astronomer and hydrographer at the naval map archives in Paris recruited by Jean Delambre. He was a mathematical progidy. In 1790, they were chosen by the National Assembly to establish a decimal system of measurement based on the meter. Since this was defined to be one ten-millionth of the distance between the Earth's pole and the equator, Mechain led a survey of the meridian arc from Dunkirk, France, to Barcelona, Spain. Through his astronomical observations, Mechain discovered 11 comets and provided 26 additions to Messier's catalog. He calculated the orbits of the two comets he found in 1781. Mechain died of yellow fever while making further surveys for the meridian measurement.«
