To some it was a miracle. Others call it the triumph of illiteracy. Somewhere between adoration and scorn. Somewhere between the carrier pigeon and television. There was and is radio. We take radio for granted. Perhaps think of it as a second rate medium. A poor relation to our pride and joy, television. But fewer than a hundred years ago, the discovery that people could communicate over great distances without wires, galvanized the world to a degree that has been equalled.

A deadly disease swept through America. It struck suddenly and mysteriously. Thousands would die. Many more would be left helpless. The disease was poliomyelitis. Polio would enlist renowned scientists, shape the vision of one of the world's greatest leaders (Franklin Roosevelt), and transform a young unknown doctor (Jonas Salk) into a world-famous hero. Ingenuity, trial and error, even acts of scientific desperation would pave the way to one of the greatest breakthroughs in scientific history.

Many rivers quenched the thirst of millions in the American west and around the world. Without these aqueducts, some of the earth's largest cities would turn into gigantic ghost towns. Their technology has been in use for over two thousand years. But today these engineering marvels cost billions of dollars to build, requiring thousands of men to toil for years on end. Aqueducts have made some men famous and others fabulously wealthy. In Los Angeles one man's vision took one hundred thousand men to complete and a great city was truly born. In Northern California the most famous conservationist of our time waged the political fight of his life in an attempt to save one of nature's most spectacular valleys from San Francisco's demand for more water.
