Seeing the Light-Properties of 400-800-Terahertz Radios [Bits Versus Electrons]

Abstract

Fire The ability to create fire freed humans from complete dependency on a point source of light and energy. (Albeit a very big point source but far away). The small fires we used to provide lighting in our homes were the forerunners of electric lights. Incandescent lights with glowing filaments aren’t all that different from fires given that wires are heated to glow just as candles and gas lamps cast off a glow.
