Jean le Rond D'Alembert

Born 16 Nov 1717; died 29 Oct 1783 at age 65. French mathematician known for his work in various fields of applied mathematics, in particular dynamics. In 1743 he published his Traité de dynamique (Treatise on Dynamics). The d'Alembert principle extends Newton's third law of motion, that Newton's law holds not only for fixed bodies but also for free moving bodies. D'Alembert also wrote on fluid dynamics, the theory of winds, the properties of vibrating strings and conducted experiments on the properties of sound . His most significant purely mathematical innovation was his invention and development of the theory of partial differential equations. He published eight volumes of mathematical studies (1761-80). He was editor of the mathematical and scientific articles for Denis Diderot's Encyclopédie.

Jigsaw puzzle

A group of girls walks into a bar. One of the women tells the bartender to line up a row of drinks for all of them. The gals lift their glasses and toast: "Here's to 51 days!" and they proceed to down their drinks.

Once again, they tell the bartender to "line 'em up" and once again they toast 51 days and down their drinks.

The bartender says: "I don’t get it. Why in the world are you toasting 51 days?"

One of the girl explains: "We just finished a jigsaw puzzle. It had written on the box '2-4 years' but we finished it in only 51 days!"
