Water and Whiskey

A professor of chemistry wanted to teach his 5th grade class a lesson about the evils of liquor, so he produced an experiment that involved a glass of water, a glass of whiskey, and two worms.
"Now, class, closely observe the worms," said the professor while putting a worm into the water.
The worm in the water writhed about, happy as a worm in water could be. He then put the second worm into the whiskey. It curled up and writhed about painfully, then quickly sank to the bottom, dead as a doornail.
"Now, what lesson can we learn from this experiment?" the professor asked.

Johnny, who naturally sits in back, raised his hand and wisely, responded confidently, "Drink whiskey and you won't get worms."

Zhores Medvedev

Born 14 Nov 1925. Zhores Aleksandrovich Medvedev is a Soviet biologist and historian who exposed the nuclear disaster which occurred in the Urals in the 1950s. For his dissident activities in his homeland, he became one of the earliest to be detained in a mental institution as the way Soviet officials attempted to stifle opposition. After he accepted a one-year invitation from the National Institute for Medical Research to work in London, in 1973, within six months of his arrival, he was forced into exile by the Soviet Union which revoked his passport. He became a senior research scientist for the NIMR . His books include The Rise and Fall of T.D. Lysenko (1969), The Medvedev Papers (1971), and Soviet Science (1978).
