Today’s quote

Silicon Graybeard:

… go outside on a clear, dark night. Wait until your eyes are used to the dark and look up. Everything you see that is shining by its own light is nuclear powered. Everything you see shining in reflected sunlight (the moon, the planets), all of that is lit by nuclear power. Now look toward your house or a nearby city. Everything you see is lit by chemical bonds being broken and re-established. As someone put it, “everything God powers is nuclear; everything man powers is fire.”

See Astronomy Photo of the Day for numerous examples of nuclear lighting.
