A Rainbow Connection


In the words of Kermit the Frog, "Why are there so many songs about rainbows and whats on the other side?". I wonder where the obsession of getting to the other side of the rainbow came from? Do you think the Wizard of Oz started it? or perhaps it was the Irish and their Leprechauns. Either way, about the only thing I know for certain is that light needs to be at a 42 degree angle for it to produce a Rainbow. Funnily enough, 42 is the answer to the Ultimate Question (life, the universe, everything!) in Douglas Adams' book The Hitch Hikers Guide To The Galaxy. However nobody knows what the Ultimate Question is. So I guess it loops back to Kermit the Frog's question, why are there so many songs about rainbows? Unanswerable questions.
