هیدی's فالی: زندگی و اختراعات انقلابی هیدی لامار، زیباترین زن جهان

What do Hedy Lamarr, avant-garde composer George Antheil, and your cell phone have in common? The answer is spread-spectrum radio: a revolutionary inven­tion based on the rapid switching of communications sig­nals among a spread of different frequencies. Without this technology, we would not have the digital comforts that we take for granted today. Only a writer of Richard Rhodes’s caliber could do justice to this remarkable story. Unhappily married to a Nazi arms dealer, Lamarr fled to America at the start of World War II; she brought with her not only her theatrical talent but also a gift for technical innovation. An introduction to Antheil at a Hollywood dinner table culminated in a U.S. patent for a jam- proof radio guidance system for torpedoes—the unlikely duo’s gift to the U.S. war effort. What other book brings together 1920s Paris, player pianos, Nazi weaponry, and digital wireless into one satisfying whole? In its juxtaposition of Hollywood glamour with the reality of a brutal war, __Hedy’s Folly__ is a riveting book about unlikely amateur inventors collaborating to change the world. Pulitzer Prize-winning author Richard Rhodes delivers a remarkable story of science history: how a ravishing film star and an avant-garde composer invented spread-spectrum radio, the technology that made wireless phones, GPS systems, and many other devices possible. Beginning at a Hollywood dinner table, Hedy's Folly tells a wild story of innovation that culminates in U.S. patent number 2,292,387 for a'secret communication system.'Along the way Rhodes weaves together Hollywood's golden era, the history of Vienna, 1920s Paris, weapons design, music, a tutorial on patent law and a brief treatise on transmission technology. Narrated with the rigor and charisma we've come to expect of Rhodes, it is a remarkable narrative adventure about spread-spectrum radio's genesis and unlikely amateur inventors collaborating to change the world. Describes the lesser-known technological talents of actress Hedy Lamarr and the collaborative work with avant-garde composer George Antheil that eventually led to the development of spread-spectrum radio, cell phones, and GPS systems.
