radio

An account of the history of the radio from its invention to the present day.

Examines the lives of, Thomas Alva Edison and NikolaTesla, two inventors, and their dizzying array of creations, and a professional rivalry that began the moment they met each other.

"You may have heard that Guglielmo Marconi invented the radio, but the inventor Nikola Tesla was working on radio technology at the same time! See how two invention powerhouses faced off in a race to create the first long-range radio"--OCLC.

Discusses twelve of the biggest moments in the history of radio.

A little over a century ago the world went wireless. Cables and all their limiting inefficiencies gave way to a revolutionary means of transmitting news and information almost everywhere, instantaneously. By means of "Hertzian waves," as radio waves were initially known, ships could now make contact with other ships (saving lives, such as on the doomed R.M.S. Titanic); financial markets could coordinate with other financial markets, establishing the price of commodities and fixing exchange rates; military commanders could connect with the front lines, positioning artillery and directing troop movements. Suddenly and irrevocably, time and space telescoped beyond what had been thought imaginable. Someone had not only imagined this networked world but realized it: Guglielmo Marconi.
