A grandfather always made a special effort with his grandchildren. Many Sunday mornings he would take his 7-year old granddaughter out for a drive in the car for some bonding time.
One particular Sunday however, he had a bad cold and he really didn't feel like being up at all. Luckily, grandma came to the rescue and said that she would take the grandchild out. When they returned, the little girl anxiously ran upstairs to see Grandpa.
"Well," the grandfather asked, "did you enjoy your ride with Granny?"
"Oh yes, Grandpa," the girl replied, "and do you know what? We didn't see a single dumb bastard or lousy shithead!"

Karl Jacobi

Born 10 Dec 1804; died 18 Feb 1851 at age 46. Karl Gustav Jacob Jacobi was a German mathematician who, with the independent work of Niels Henrik Abel of Norway, founded the theory of elliptic functions. He also worked on Abelian functions and discovered the hyperelliptic functions. Jacobi applied his work in elliptic functions to number theory. He also investigated mathematical analysis and geometry. Jacobi carried out important research in partial differential equations of the first order and applied them to the differential equations of dynamics. His work on determinants is important in dynamics and quantum mechanics and he studied the functional determinant now called the Jacobian.[a.k.a Carl Jacobi]
