One idea I take great exception to is the notion that understanding a bit about how something awesome works somehow destroys some special ability to appreciate the awesomeness of it. In my experience, it absolutely does not.
This is an example of thin film interference, where light reflecting from the top and bottom of a crack in a polished quartz pebble destructively interferes with itself. It's damn pretty, whether you care to follow the maths or not.
(Actually the most accessible explanation I could come up with was in the Wikipedia entry on soap bubbles. This includes the one I attempted to write myself.)
