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 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."
