Good thinking

Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.

As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.

The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.

When questioned about her choice, the blonde replies:

"Well, if I get hot, I can roll down the window!"

Pierre René Deligne

Born 3 Oct 1944.Belgian mathematician who was awarded the Fields Medal at the International Congress of Mathematicians in Helsinki, Finland, in 1978 for his work in algebraic geometry. His work originated with André Weil's ideas on polynomial equations which led to three questions on what properties of a geometric object can be determined purely algebraically. These three problems quickly became major research challenges to mathematicians. A solution of the three Weil conjectures was given by Deligne. This work brought together algebraic geometry and algebraic number theory. The solution to these problems had required the development of a new kind of algebraic topology.
