Maurice de Broglie

Born 27 Apr 1875; died 14 Jul 1960 at age 85.(6th duke) (Louis-César-Victor-) Maurice de Broglie was a French physicist who made many contributions to the study of X rays. While in the navy (1895-1908), he first distinguished himself by installing the first French shipboard wireless. From 1912, his chief interest was X-ray spectroscopy. His “method of the rotating crystal” was an application of Bragg's “focussing effect” to eliminate spurious spectral lines. De Broglie discovered the third L absorption edge (1916), which led to the exploration of “corpuscular spectra.” During 1921-22, he worked with his brother Louis to refine Bohr's specification of the substructure of the various atomic shells. He also did pioneer work in nuclear physics and cosmic radiation.

A woman walked up to a little...

A woman walked up to a little old man rocking in a chair on his porch. "I couldn't help noticing how happy you look," she said. "What's your secret for a long happy life?"
"I smoke three packs of cigarettes a day," he said. "I also drink a case of whiskey a week, eat fatty foods, and never exercise."
"That's amazing," said the woman, "how old are you?"
"Twenty-six," he said.
