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. The creative applications for these small and
efficient devices are endless: on tape, on wallpaper, even in contact
lenses. They will set the world aglow. But is a brighter world a
better one?
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?
