    We live in a world of waves. The radio waves hitting your car’s antenna and the light coming in through its windshield, the X-rays that can detect a tumor and the gamma radiation that can destroy it are all different facets of the same phenomenon: electromagnetism. As one of the fundamental forces of nature, its imprint can be felt on almost everything in the universe.
