The Bridge of the Gods

Okay, someone really needs to reprint Isaac Asimov’s excellent essay, “The Bridge of the Gods” which is all about light and rainbows. I’ve been seeing stuff all over about remarkable “double-rainbows” as if this is a new or even a rare phenomenon, but as Asimov explains in his essay, there is a very good explanation not only for the formation of a double-rainbow, but the geometry behind it.
