Zapped : from infrared to x-rays, the curious history of invisible light / Bob Berman

I learned so many interesting facts about electromagnetism!  First off,” photons constitute 99.9999999 percent of everything. The universe is literally made of light.” Berman explains that radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays and gamma rays are all forms of light. He goes on to detail their discoveries made in the 19th century by brilliant scientists and how technology uses them today. Fascinating stuff!     Celeste 12/4/2017
