Pizza

A college pizza delivery boy arrived at the house of Mr.Smith. He delivered the pizza to his trailer. After giving it to him, Mr. Smith asked: "What is the usual tip?"
"Well," replied the youth, "this is my first trip here, but the other guys say if I get a quarter out of you, I'll be doing great."
"Is that so?" snorted Mr. Smith. "Well, just to show them how wrong they are, here's five dollars."
"Thanks," replied the youth, "I'll put this in my school fund."
"What are you studying in school?" asked Larry.
The lad smiled and said: "Applied psychology."

Atle Selberg

Died 6 Aug 2007 at age 90 (born 14 Jun 1917).Norwegian mathematician who is one of the foremost analytic number theorists. After working in isolation during WW II, due to the occupation of Norway by the Nazis, his accomplishments in the theory of the Riemann zeta function became known. During the 1950's he developed the Selberg trace formula, his most famous accomplishment. It establishes a duality between the length spectrum of a Riemann surface and the eigenvalues of the Laplacian which is analogous to the duality between the prime numbers and the zeros of the zeta function. He was awarded the Fields Medal in 1950 for his work in number theory on generalisations of the sieve methods of Viggo Brun. In 1986 he won the Wolf Prize.
