Bubba applied for an engineeri...

Bubba applied for an engineering position at a Lake Charles refinery. A Yankee applied for the same job and both applicants having the same qualifications were asked to take a test by the manager. Upon completion of the test, both men only missed one of the questions. The manager went to Bubba and said: "Thank you for your interest, but we've decided to give the Yankee the job."Bubba asked: "And why are you giving him the job? We both got nine questions correct. This being Louisiana, and me being a Southern boy, I should get the job!"
The manager said: "We have made our decision not on the correct answers, but rather on the one question that you both missed."
Bubba then asked: "And just how would one incorrect answer be better than the other?"
The manager replied: "Bubba, its like this. On question #4 the Yankee put down; "I don't know." You put down, "Neither do I."

George Robert Stibitz

Born 30 Apr 1904; died 31 Jan 1995 at age 90.U.S. mathematician who was regarded by many as the "father of the modern digital computer." While serving as a research mathematician at Bell Telephone Laboratories in New York City, Stibitz worked on relay switching equipment used in telephone networks. In 1937, Stibitz, a scientist at Bell Laboratories built a digital machine based on relays, flashlight bulbs, and metal strips cut from tin-cans. He called it the "Model K" because most of it was constructed on his kitchen table. It worked on the principle that if two relays were activated they caused a third relay to become active, where this third relay represented the sum of the operation. Also, in 1940, he gave a demonstration of the first remote operation of a computer.
