Stefan Banach

Born 30 Mar 1892; died 31 Aug 1945 at age 53.Polish mathematician who founded modern functional analysis and helped develop the theory of topological vector spaces. In addition, he contributed to measure theory, integration, the theory of sets, and orthogonal series. In his dissertation, written in 1920, he defined axiomatically what today is called a Banach space. The idea was introduced by others at about the same time (for example Wiener introduced the notion but did not develop the theory). The name 'Banach space' was coined by Fréchet. Banach algebras were also named after him. The importance of Banach's contribution is that he developed a systematic theory of functional analysis, where before there had only been isolated results which were later seen to fit into the new theory.

A lady goes to the doctor and...

A lady goes to the doctor and complains her husband is losing interest in sex.
He gives her a pill but warns her that it's still experimental. He tells her to slip it in his mashed potatoes at dinner. At dinner that night, she does just that.
About a week later she's back at the doctor and tells him, "The pill worked great! I put it in his mashed potatoes like you said.
It wasn't five minutes later that he jumped up, pushed all the food and dishes to the floor, grabbed me, ripped off all my clothes and ravaged me right there on the table."
The doctor says, "Oh dear -- I'm sorry, we didn't realize the pill was that strong. The foundation will be glad to pay for any damages."
The lady replied, "That's very kind - but I don't think the restaurant will let us back in anyway."
