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!"

Dayton Clarence Miller

Born 13 Mar 1866; died 22 Feb 1941 at age 74. American physicist. Author of The Science of Musical Sounds (1916). Miller's collection of nearly 1,650 flutes and other instruments, and other materials mostly related to the flute, is now at the Library of Congress. To provide a mechanical means of recording sound waves photographically, he invented the phonodeik (1908). He became expert in architectural ecoustics. During WW I, he was consulted concerning using his photodeik to help locate enemy guns. Miller spent considerable research effort on repeating the Michelson and Morley experiment, proposed by Maxwell, to detect a stationary aether. He spent some time working with Morley (1902-4), then more time at Mt. Wilson, recording results favoring the presence of the aether.
