Shortly here on Brilliant, I will be making a series of posts that delve into the wonders of the Golden Ratio. I'm not exactly sure how long this will go on for, but I plan to post articles every one or two days. I will *try* to make them short, but bear with me, I can get carried away sometimes. The articles will start out at the level of the Cosines Group, but will eventually elevate to the Torque group. I may also be posting about background information necessary to understand the golden ratio, so keep an eye out for those too. Other than that, I hope that you're all looking forward to this as much as I am.

Here's a bit of a teaser: Why do the seeds of the sunflower pictured above spiral in the way they do?

TopNewestDag nabbit. You beat me to it. I was going to do Fibonacci numbers but I see that sooner or later you'll cover them.

Well good luck on your endeavor.

Haha! The secrets are to be revealed. :) Thanks for waiting. I do plan to cover Fibonacci numbers and other sequences like them.

I would highly suggest this video: http://vimeo.com/9953368

Oh yes. I discovered that video in a page on AoPS, and it has never failed to amaze me.

They do this so the petals on the top don't cover the petals on the bottom. They do this by following the Fibonacci sequence like this: one petal blooms and the second petal goes \(\frac {1}{2}\) the way around the middle, then \(\frac {2}{3}\) of the way around it, then \(\frac {3}{5}\) of the way around it and so forth.

You've solved the problem of the petals, but what about the seeds?

I don't know but I think it may be to do with calculus.
