(1) One billionth of a second. Used to measure the speed of logic and memory chips, a nanosecond can be visualized by converting it to distance. In one nanosecond, electricity travels approximately a foot in a wire. Admiral Grace Hopper was famous for handing out strands of "telephone wire nanoseconds" to her audience whenever she lectured about technology. Holding the wire turns the unreal concept of a billionth of a second into reality.
