### Spaghetti

A wealthy man was having an affair with an Italian woman for several months. One night, during one of their rendezvous, she confided in him that she was pregnant. Not wanting to ruin his reputation or his marriage, he paid her a large sum of money if she would go to Italy to secretly have the child. If she stayed in Italy to raise the child, he would also provide child support until the child turned 18. She agreed, but asked how he would know when the baby was born. To keep it discreet, he told her simply to mail him a post card, and write "Spaghetti" on the back. He would then arrange for child support payments to begin.
One day, about 9 months later, he came home to his confused wife. "Honey," she said, "you received a very strange post card today."
"Oh, just give it to me and I'll explain it" he said.
The wife obeyed, and watched as her husband read the card, turned white, and fainted.
On the card was written: "Spaghetti, Spaghetti, Spaghetti. Two with meatballs, one without."

### Pierre de Fermat

Born 17 Aug 1601; died 12 Jan 1665 at age 63. French mathematician who has been called the founder of the modern theory of numbers. Together with Rene Descartes, Fermat was one of the two leading mathematicians of the first half of the 17th century. He anticipated differential calculus with his method of finding the greatest and least ordinates of curved lines. He proposed the famous Fermat's Last Theorem while studying the work of the ancient Greek mathematician Diophantus. He wrote in pencil in the margin, “I have discovered a truly remarkable proof which this margin is too small to contain,” that when the Pythagorean theorem is altered to read an + bn = cn, the new equation cannot be solved in integers for any value of n greater than 2.
