A professor of chemistry wanted to teach his 5th grade class a lesson about the evils of alcohol, so he produced an experiment that involved a glass of water, a glass of whiskey and two worms."Now, class. Observe closely the worms," said the professor putting a worm first into the water. The worm in the water writhed about, happy as a worm in water could be.
The second worm, he put into the whiskey. It writhed painfully, and quickly sank to the bottom, dead as a doornail.
"Now, what lesson can we derive from this experiment?" the professor asked.
Little Johnny, who naturally sits in back, raised his hand and wisely, responded...
"Drink whiskey and you won't get worms!"

Paul Crutzen

Born 3 Dec 1933. Paul Josef Crutzen is a Dutch chemist who received the 1995 Nobel Prize for Chemistry for demonstrating, in 1970, that chemical compounds of nitrogen oxide accelerate the destruction of stratospheric ozone, which protects the Earth from the Sun's ultraviolet radiation. His work, published in 1970, that showed that the nitrogen oxides NO and NO2 react catalytically with ozone, thus accelerating the rate of ozone breakdown to O2 in the stratosphere. These nitrogen oxides are formed principally by decay of nitrous oxide (N2O) which originates from microbiological transformations in the soil. He shared the prize with chemists Mario Molina and F. Sherwood Rowland, who discovered in 1974 that manufactured chlorofluorocarbon gases also contribute to ozone depletion.
