Vacuum tube

In 1906, Dr. Lee DeForest (26 Aug 1873 - 30 Jun 1961), one of the “fathers of radio,'' announced his three-element electrical vacuum tube (now known as a triode) to a meeting of the American Institute of Electrical Engineers He had discovered that when a mesh, or grid, of wire was placed between the filament and collector “plate” in a diode tube (first made by J. Ambrose Fleming, 1904), a large voltage-amplifying effect could be produced. DeForest patented this vacuum tube on 15 Jan 1907. The ability of this tube to amplifiy weak signals was an invention as great as radio itself, because it made long-distance communication possible.[Image: early DeForest Audion]

Three Policemen at the Pearly Gates

Three police officers were standing in line at the Pearly Gates.Saint Peter asked the first officer, “What did you do with your life?”“I was a police officer,” he responded.“What kind of police officer?” Saint Peter asked.“I was a vice officer. I kept drugs off the streets and out of the hands of kids.”“Welcome to heaven. You may end the gates.”He asked the second man what he did as a police officer.“I was a traffic officer,” said the man. “I kept the roads and highways safe.”“Welcome to heaven. You may enter the gates.”He asked the third man what he did as a police officer.“I was a military policeman, sir,” replied the man.“Wonderful! I’ve been waiting for you all day!” replied Saint Peter. “I need to take a break! Watch the gate, will you?”
