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

Integrated circuit

In 1952, the concept of the integrated circuit chip was first presented, at a Symposium on Progress in Quality Electronic Components in Washington DC., by radar scientist Geoffrey W.A. Dummer. His small team of researchers at the Royal Radar Establishment of the British Ministry of Defence, based at Malvern, Worcestershire, was working on the task of improving the reliability of the Royal Air Force's radar equipment.. He believed that it would be possible to fabricate multiple circuit elements on and into a block of silicon half an inch square. In 1956, his initial attempts to build such a circuit failed, and thereafter could get no further support for his idea. Britain lost the commercial lead. A few years later, in America, Jack Kilby of Texas Instruments was awarded a U.S. patent for essentially the same idea.«
