A man walks into the Friars barbershop, sits down in the chair and the barber asks, “How do you want your haircut?”
The man says, ” I would like the sideburns one high and one low, a few long hairs sticking out of the back and a few chunks on the side and top.”
The barber looks puzzled and says, “I’m not sure I can do that.”
The customer says, “Why not, you did it that way last time.”
Donald B. KeckBorn 2 Jan 1941.American research physicist, who with his colleagues at Corning Glass, Dr. Robert Maurer and Dr. Peter Schultz, invented fused silica optical waveguide - optical fiber. This was a breakthrough creating a revolution in telecommunications, capable of carrying 65,000 times more information than conventional copper wire. In 1970, Maurer, Keck, and Schultz solved a problem that had previously stumped scientists around the world. They designed and produced the first optical fiber with optical losses low enough for wide use in telecommunications. The light loss was limited to 20 decibels per kilometer (at least one percent of the light entering a fiber remains after traveling one kilometer). |
