A young woman had severe PMS...

A young woman had severe PMS, so she asked a friend to recommend a gynecologist. "I know a great one," the friend said, "but he's very expensive. He charges $500 for the first visit and $150 for each visit after that."

He then proceeded to examine her.
"Very good," he said when he was finished. "Just continue the treatment I prescribed last time."

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.«
