Paul Horowitz

Paul Horowitz (born 1942) is a U.S. physicist and electrical engineer, known primarily for his work in electronics design, as well as for his role in the search for extraterrestrial intelligence (see SETI).

At age 8, Horowitz achieved distinction as the world's youngest amateur radio operator (or "ham"). He went on to study physics at Harvard University (B.A., 1965; M.A., 1967; Ph.D., 1970), where he has also spent all of his subsequent career. His early work was on scanning microscopy (using both protons and X-rays). Horowitz has also conducted astrophysical research on pulsars and investigations in biophysics. His interest in practical electronics has led to a handful of inventions, including an automated voting machine and an acoustic mechanism for landmine detection. Since 1974 he has taught a practical course in electronics whose lecture notes became one of the best known textbooks in the field: "The Art of Electronics" (coauthored with Winfield Hill).

Horowitz was one of the pioneers of the search of intelligent life beyond the Earth, and one of the leaders behind SETI. This work has attracted both admiration and ridicule. Harvard biologist Ernst Mayr has sharply criticized Horowitz for wasting the resources of the university and the efforts of graduate students on such an endeavour. Carl Sagan, on the other hand, was believed to have based the main character in his novel "Contact" partly on HorowitzVerify source|date=July 2007.

Horowitz claims SETI has found 37 signals "which survived all our cuts" and cannot be positively identified. On September 10, 1988 the university's 84-foot radio dish detected "an enormous spike which was 750 times noise. If you converted the radio signal into audio it would sound just like a tone. It would sound like a flute." All 37 signals, however, have been single events which have never been heard again. [cite web

Horowitz holds professorial appointments at Harvard in both physics and electrical engineering. He has also served as a member of the JASON Defense Advisory Group.
