Armand-Hippolyte-Louis Fizeau

Died 18 Sep 1896 at age 76 (born 23 Sep 1819). French physicist who was the first to measure the speed of light successfully without using astronomical calculations (1849). Fizeau sent a narrow beam of light between gear teeth on the edge of a rotating wheel. The beam then traveled to a mirror 8 km/5 mi away and returned to the wheel where, if the spin were fast enough, a tooth would block the light. Knowing this time from the rotational speed of the wheel, and the mirror's distance, Fizeau directly measured the speed of light. He also found that light travels faster in air than in water, which confirmed the wave theory of light, and that the motion of a star affects the position of the lines in its spectrum. With Jean Foucault, he proved the wave nature of the Sun's heat rays by showing their interference (1847).

A doctor at an insane asylum decided to take his inmates to a baseball game. For weeks in advance, he coached his patients to respond to his commands. When the day of the game arrived, everything seemed to be going well.

As the national anthem started, the doctor yelled, "Up nuts!" And the inmates complied by standing up. After the anthem he yelled, "Down Nuts!" And they all sat. After a home run he yelled, "Cheer nuts!" And they all broke into applause and cheers.

Thinking things were going well, he decides to go get a beer and a hot dog, leaving his assistant in charge. When he returned there was a riot in progress. Finding his assistant, he asked what happened.

The assistant replied, "Well, everything was fine until some guy walked by and yelled, PEANUTS!'"
