SUPERCONDUCTIVITY AND THE OFFICE OF THE FUTURE Available to Purchase

Superconductivity has been around for most of this century. In 1911 Kamerlingh Onnes, a Dutch physicist, discovered that the resistance of mercury to electric current dropped effectively to zero at 4° Kelvin. This extremely low temperature — 452°F below zero — was able to be achieved by his production, three years earlier, of liquid helium.
