Kiss

One day a teacher had a taste test with her students. She picked a little boy to do the first test. She blindfolded him, put a Hershey kiss in his mouth and asked, "Do you know what it is?
"No, I don't," said the little boy
"Okay, I'll give you a clue. It's the thing your daddy wants from your Mom before he goes to work."
Suddenly, a little girl at the back of the room yelled, "Spit it out! It's a piece of ass!"

Lewis Fry Richardson

Died 30 Sep 1953 at age 71 (born 11 Oct 1881). British physicist and psychologist who first applied mathematics to accurate weather prediction. Richardson applied the mathematical method of finite differences to predicting the weather (1922). In his life, he held various posts: at the National Physical Laboratory, the Meteorological Office, and several university posts in physics or technology. Also, he was a chemist with National Peat Industries and in charge of the physical and chemical laboratory of the Sunbeam Lamp Co. Early application of mathematical techniques for systematically forecasting the weather were limited by extensive computation time: three months to predict weather for the next 24 hours. With electronic computers available after WW II made his methods became practical. He wrote several books applying mathematics to the causes of war. He contributed to calculus and the theory of diffusion for eddy-diffusion in the atmosphere. The Richardson number, a quantity involving gradients (change over distance) of temperature and wind velocity, is named after him.
