Laying Turf

A painting contractor was speaking with a woman about a job. In the first room, she said she would like a pale blue. The contractor wrote this down and went to the window, opened it, and yelled out "GREEN SIDE UP!" In the second room, she told the painter she would like it painted in a soft yellow. He wrote this on his pad, walked to the window, opened it, and yelled "GREEN SIDE UP!" The lady was somewhat curious but she said nothing. In the third room, she said she would like it painted a warm rose color. The painter wrote this down, walked to the window, opened it and yelled "GREEN SIDE UP!" The lady then asked him, "Why do you keep yelling 'green side up'?"

"I'm sorry," came the reply.

"But I have a crew of blondes laying sod across the street."

Pierre-Louis Dulong

Died 18 Jul 1838 at age 53 (born 12 Feb 1785).French chemist and physicist who helped formulate the Dulong-Petit law of specific heats (1819), which proved useful in determining atomic weights. He began in a medical career, but turned to botany and then chemistry. In 1811, he discovered nitrogen trichloride, losing a finger and the sight of one eye when it spontaneously exploded. Jointly with Alexis Petit (1815-20), they measured the specific heat of elements and related them to atomic weights. They discovered their new law that specific heat times atomic weight of an element is a constant, about six calories per gram atom, the same for all solid elements.«
