Once upon a time there was a s...

Once upon a time there was a shepherd looking after his sheep on the edge of a desert road. Suddenly a brand new Jeep Cherokee screeches to a halt next to him. The driver a young, a man dressed in a Brioni suit, Ceruti shoes, Ray-Ban sunglasses and a YSL tie, gets out and asks the shepherd, "If I guess how many sheep you have, would you give me one of them?"
The shepherd looks at the young man, then looks at the sheep, "All right."
The young man parks the car, connects his notebook to his cell phone, enters a NASA site, scans the ground using his GPS, opens a database and 60 Excel tables filled with algorithms, then prints out a 150-page report on his high-tech mini-printer.
"You have exactly 1,586 sheep," he declares.
"That's correct," says the shepherd. "You may take the sheep."
The young man takes the sheep and puts it in the back of his car.
The shepherd asks, "If I guess your profession, will you return my sheep?"
"Why not?" answers the young man.
"You're a Consultant," declares the shepherd confidently.
"That's amazing! How did you guess so quickly and easily?" asks the man.
"Very simple," replies the shepherd. "First you came here without being called. Secondly, you charge me to tell me something I already knew. And thirdly, you do not understand anything about what I do. And lastly you took my sheepdog..."

Marie Curie

Born 7 Nov 1867; died 4 Jul 1934 at age 66. Marie Sklodowska Curie was a Polish-French chemist and physicist whose celebrated experiments (1898) on uranium minerals led to discovery of two new elements. First she separated polonium, and then radium a few months later. The quantity of radon in radioactive equilibrium with a gram of radium was named a curie (subsequently redefined as the emission of 3.7 x 1010 alpha particles per sec.) With Henri Becquerel and her husband, Pierre Curie, she was awarded the 1903 Nobel Prize for Physics. Later, she also was sole winner of a second Nobel Prize in 1911, this time in Chemistry. Her family won five Nobel awards in two generations. She died of radiation poisoning from her pioneering work before the need for protection was known.
