A fellow came into a bar and ordered a martini. Before drinking it, he removed the olive and carefully put it into a glass jar. Then he ordered another martini and did the same thing. After an hour, when he was full of martinis and the jar was full of olives, he staggered out.
"Well," said a customer, "I never saw anything as peculiar as that!"
"What's so peculiar about it?" the bartender said. "His wife sent him out for a jar of olives."
Ivar FredholmDied 17 Aug 1927 at age 61 (born 7 Apr 1866).Erik Ivar Fredholm was a Swedish mathematician who is remembered for Fredholm integral equations with applications in mathematical physics and actuarial science. His first paper (1890) was on a special class of functions inspired by the heat equation. His 1898 doctoral dissertation involved a study of partial differential equations motivated by an equilibrium problem in elasticity. Fredhlom also had a career in actuarial science and from 1902 onwards he studyied various questions in this area, including an elegant formula he proposed to determine the surrender value of a life insurance policy. He built a machine to solve differential equations. David Hilbert extended one of Fredholm's integral equations discoving Hilbert spaces on which would be built the quantum theory.« |
