The invention of "waves" - as in radio waves or electromagnetic fields - has led to many great inventions. This program examines how the ability to transmit music, conversations, pictures, or data invisibly through the air, over thousands of miles, has changed our lives. Whether we are talking about cell phones, microwave ovens, TVs, RADAR systems, or any one of the thousands of other wireless technologies, all of them use radio waves to communicate. The list of surprising discoveries goes on, from X-rays to scans of our most intimate parts. What's next? Improving our understanding of the human brain? Yes, EM waves see all.
