Crash and Burn

Two men got out of their cars after they collided at an intersection. One took a flask from his pocket and said to the other, "Here, maybe you'd like a nip to calm your nerves."
"Thanks," he said, and took a long pull from the container. "Here, you have one, too," he added, handing back the whiskey.
"Well, I'd rather not," said the first. "At least not until after the police have been here."

Albert Wallace Hull

Born 19 Apr 1880; died 22 Jan 1966 at age 85.American physicist who independently discovered the powder method of X-ray analysis of crystals (1917), which permits the study of crystalline materials in a finely divided microcrystalline, or powder, state. His first work was on electron tubes, X-ray crystallography, and (during WW II) piezoelectricity. In the 1920's, he studied noise measurements in diodes and triodes. In the 1930's, he also took interest in metallurgy and glass science. His best-known work was done after the war, especially his classic paper on the effect of a uniform magnetic field on the motion of electrons between coaxial cylinders. He also invented the magnetron (1921) and the thyratron (1927), and other electron tubes with wide application as components in electronic circuits.
