1. Research And Development
... now dependent upon microprocessors-computer chips made from crystals of silicon and small amounts of other elements. Silicon, an excellent material for controlling electrons, is a semiconductor. Superconductivity, the flow of electricity without resistance, was discovered in 1911, but it was phenomenon that could occur only at extremely low temperatures. In order to superconduct, metals needed to be immersed in F making the ... engineering world. Since then, superconductors had become the catchphrase springing loose money for research and fantasies for about "flying" trains that travel ...
