History - It was on this day in 1847 that Thomas Alva Edison was born. He was a prolific American inventor who developed the practical electric light bulb, an electric generating system, a sound-recording device, and a motion picture projector.

Quote - The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angeles. The wireless is the same, only without the cat. - Albert Einstein
Fact - In 1958 when Jack Kilby invented the first IC it was a simple audio oscillator and only had one transistor. Bob Noyce is also credited with the invention of the IC as he set down many of the processes required.
