“Among the many fields of present‐day physics which promise significant contributions to the automotive industry in the near future, is the physics of the ‘solid‐state’.” These words, spoken in a March 1938 address by Cornell University physicist Floyd K. Richtmyer, proved to be prophetic. Today, virtually every vehicle on the road has some solid‐state component in its electrical system. In fact, the newest American automobiles embody integrated circuit technology in the form of durable microcomputers, which are an essential part of electronic engine‐control systems. Such systems are just one example of the important role that physics has played in the progress of the US automotive industry.
