re: #88 Mattand
I thought rainbows were about tracking down the leprechauns at their ends, and mugging them for their pots of gold.
For my part, I like how a little bit of science can let one calculate the angles for a single and double rainbow from the geometry of a water drop, and these angles agree with observations.
Far more interesting than some mythical explicit promise to never again do something which hadn’t happened in the first place.
