Gottlob Frege

Died 26 Jul 1925 at age 76 (born 8 Nov 1848). Friedrich Ludwig Gottlob Frege was a German mathematician and logician who founded modern symbolic logic and was the first to show mathematics as actually an extension of logic. He extended Boole's work by inventing logical symbols (symbols for “or”, “if-then”, etc.) that improved on the syllogistic logic it replaced. He also worked on general questions of philosophical logic and semantics. His theory of meaning, based on makig a distinction between what a linguistic term refers to and what it expresses, is still influential. Frege tried to provide a rigorous foundation for mathematics on the basis of purely logical principles, but abandoned the attempt when Bertrand Russell, on whose work he had a profound influence, pointed out a paradox that made the system inconsistent.

A mechanic was removing a cylinder head from the motor of a Harley motorcycle when he spotted a well-known heart surgeon in his shop.
The surgeon was there, waiting for the service manager to come and take a look at his bike.
The mechanic shouted across the garage, "Hey, Doc, can I ask you a question?"
The surgeon a bit surprised, walked over to the mechanic working on the motorcycle.

The mechanic straightened up, wiped his hands on a rag and asked, "So Doc, look at this engine. I open its heart, take the valves out, fix 'em, put 'em back in, and when I finish, it works just like new. So how come I get such a small salary and you get the really big bucks, when you and I are doing basically the same work?"
The surgeon paused, smiled and leaned over, and whispered to the mechanic, "Try doing it with the engine running."
