Big Picture Science – The Light Stuff

The light bulb needs changing. Edison’s incandescent bulb, virtually unaltered for more than a century, is now being eclipsed by the LED.

Discover the many ingenious applications for LEDs and the brilliance of the 19th century scientist, James Clerk Maxwell, who first discovered just what light is. But both biologists and astronomers are alarmed by the disappearance of dark. Find out how light pollution is making us and other animals sick and – when was the last time you saw a starry night?
