Gave a program tonight on the Fibonacci numbers, the Golden Spiral, and the Golden Ratio. This isn't the best photo, but I do love the interplay of math and nature you can see in the sunflower.
Thats really weird! My eye was instantly attracted to the thumbnail of this photo and I was going to ask if you know about the Golden Ratio :) Seen as you give programs on it I think its safe to assume you do :-D
