Abuse me for I will not care...

Abuse me for I will not care. Curse me when I stray from fair. Brute force won't put me in my place. Smooth and even wins the race. Envy colors where I rest. No sandy beaches for the best. What is it?

Armand-Hippolyte-Louis Fizeau

Born 23 Sep 1819; died 18 Sep 1896 at age 76. 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).
