Sun, rain, sun, rain - yep the schizo Scottish weather where you can be putting on your shades then putting up a brolly minutes later... Still, down at North Berwick again with Gordon and his four-legged chum Bruce the bright side of the rapidly changing weather meant we had this gorgeous but brief rainbow appear. I couldn't fit it all in I'm afraid, but this was the first time in I don't know how long that either of us had seen a full arch rainbow rather than just a fragment of arc. It rose up out of the whitecap waves in front of the rocky island and arcing over our heads to land down somewhere behind the trees. Utterly gorgeous, brief and ephemeral, like the best parts of life. Unfortunately wasted on poor Bruce who , being a dog, isn't able to groove on the colours.
Naturally we thought on getting out the spade and looking for our pot of gold. This then lead us to the discussion that folklore says there is Faery gold at the end of a rainbow, while science, drawing from Newton's work with prisms, tells us that it is a visual phenomena caused by refraction and reflections. However as no-one can get to the end of a rainbow to dig it up then the folkloric hypothesis is actually still valid according to scientific methodology, i.e. in order to properly disprove it we require solid proof (and in an easily repeatable fashion). And anyway the folkloric version sounds better!
