Like the surface of the butterfly's eye, they use a series of protrusions to trap incoming waves.<br /><br />Great post, thanks.Chris Jefferieshttps://www.blogger.com/profile/07024046243018838005noreply@blogger.comtag:blogger.com,1999:blog-36070744.post-59323091794355979972010-02-04T00:24:04.848+00:002010-02-04T00:24:04.848+00:00Very cool but I couldn't help but think of the...Very cool but I couldn't help but think of the poor tethered goat in Jurrasic Park.

My goat has been well-behaved throughout! But then I don't know much about goats...<br /><br />@Andy Russell - funnily enough I found someone else had made the house of cards part of the analogy before me, I must have read it without realising.<br /><br />The scattering part of the analogy is a bit wobbly, the reason I entered into the whole goat thing, is I realised that waves were something physicists took for granted but really aren't that intuitive if you think about them from scratch.SomeBeanshttps://www.blogger.com/profile/11076372969807940310noreply@blogger.comtag:blogger.com,1999:blog-36070744.post-39837758196185635252010-02-03T16:03:05.612+00:002010-02-03T16:03:05.612+00:00Wow, you are the analogy king!

The butterfly one is from wikipedia and marked public domain.<br /><br />@RothschildOrchid - a goat seemed just the right sort of animal for the analogy but I don't know anything about goats.<br /><br />@HappyMouffetard yes - and a fine photo too!<br /><br />@Nora_Lumiere - colour reproduction is a whole world of blog posts! Our eyes can see a much large range of colours than pretty much any commonly available display. The problem is that we can't make the three primaries "good enough" to cover the visual gamut.
