spirals and sequences

I’m pursuing the Fibonacci sequence for something I’m writing and have noticed it’s everywhere! This morning I was watering the cucumber box, over which a huge sunflower presides. And here’s what I saw:

P1080482

Sunflowers are excellent examples of the Fibonacci sequence because the seedheads in the centre of the flower are organized in two sets of spirals — short ones running clockwise from the centre, and longer ones running counter-clockwise. If you count the spirals in a consistent manner, apparently you will always find a Fibonacci number.

And that bee at work — the family trees of both drones and workers are examples of the Fibonacci sequence.

I’ve come so late to all this and am wandering around amazed.
