Deceptive advertising: the breakthrough invention(s) received short shrift. I was hoping for more science, less romance!

hi

A mind-opening and entertaining read for cellphone/GPS/WiFi users who are curious to know how their gadgets work.

Hedy’s earlier film Ecstasy went viral; she was courted by and married an international arms trader; bored as a potiche, she escaped to Hollywood, befriended a bad boy music composer and together they invented the basis of modern day telecommunication technology.

Simply put, when two moving objects (airplane-torpedo, satellite-cellphone user) communicate with just one frequency, their signal can be easily intercepted and jammed. Their solution is synchronized frequency hopping, now called spread spectrum, i.e. transmitter and receiver rapidly switch from one frequency to another to prevent jamming. Today’s cell phones and many other telecommunication devices work on the same principle with microwaves instead of radio waves. Years ago, radio was called wireless, now it’s Wi-Fi, déjà-vu? Read the 3-4 page Introduction, like? Read the Afterword, still like? Then enjoy the whole enchilada!

"Among the most intriguing bits of Hollywood lore is the real-life story of Hedwig Kiesler, the Vienna-born Jewish actress who fled Nazi Germany for America, where she reinvented herself as Hedy Lamarr. However, her movie star persona wasn't her only invention: to support the U.S. war effort, this savvy siren of the silver screen teamed up with avant-garde composer George Antheil to develop a technology known as frequency-hopping spread spectrum - an invention that would ultimately pave the way for bar code readers, cell phones, Wi-Fi, and GPS."

This was a fascinating book. It talked about Hedy Lamarr, the famous actress, but only to set up the story of her inventions. She and a music composer friend came up with spread spectrum technology in an attempt to help out the US navy with torpedoes, which the navy rejected. The got a patent on the technology, however, and it proved to be the basis for wireless phones, Bluetooth networks, GPS devices, and military communications. I learned a lot and enjoyed finding out what drove her to invent while still being an actress. The book is a little slow at first, but picks up as it goes along.

Such a beautiful woman, it is somehow stunning that she is also very smart, intelligent and scientific.

Take a close look at the cover art. It looks as if she is retaining water in her ankles...that shoe strap looks buried behind a roll of fat, lol.

Well, I had to find something wrong with her, didn't I?

Seriously, for those of us interested in patents on hopping frequencies as they relate to radio controlled torpedoes will find this book fascinating.
