The Lawyer at the Pearly Gates

Recently a teacher, a garbage collector, and a lawyer wound up together at the Pearly Gates. St. Peter informed them that in order to get into heaven, they would each have to answer one question.St. Peter addressed the teacher and asked, “What was the name of the ship that crashed into the iceberg? They just made a movie about it.” The teacher answered quickly, “That would be the Titanic.” St. Peter let her through the gate.St. Peter turned to the garbage man and figuring heaven didn’t REALLY need all the odors this guy would bring with him, decided to make the question a little harder: “How many people died on the ship?” But the trash man had just seen the movie, too, and he answered, “about 1,500.”“That’s right! You may enter,” said Peter.Then St. Peter turned to the lawyer and said, “Name them.”

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).
