A man and his wife were drivin

A man and his wife were driving their RV across the country and were nearing a town spelled Kissimee. They noted the strange spelling and tried to figure how to pronounce it - KISS-a-me; kis-A-me; kis-a-ME. They grew more perplexed as they drove into the town.
Since they were hungry, they pulled into a place to get something to eat. At the counter, the man said to the waitress: "My wife and I can't seem to be able to figure out how to pronounce this place. Will you tell me where we are and say it very slowly so that I can understand."
The waitress looked at him and said: "Buuurrrgerrr Kiiiinnnng."

Aleksandr Osipovich Gelfond

Born 24 Oct 1906; died 7 Nov 1968 at age 62.Russian mathematician who originated basic techniques in the study of transcendental numbers (numbers that cannot be expressed as the root or solution of an algebraic equation with rational coefficients). He profoundly advanced transcendental-number theory, and the theory of interpolation and approximation of complex-variable functions. He established the transcendental character of any number of the form ab, where a is an algebraic number different from 0 or 1 and b is any irrational algebraic number, which is now known as Gelfond's theorem. This statement solved the seventh of 23 famous problems that had been posed by the German mathematician David Hilbert in 1900.
