Here is Part 2 in Vi Hart’s wonderful Doodling In Math series. Following on from last week’s Part 1 we continue our journey of spiral discovery and the occurrence of Fibonacci numbers in nature.
So now you know how to at least try and think like a mathematical minded plant, and of course how to make the ever-useful angle-a-tron and discover the golden ratio of Phi (Φ).
Part 3 coming soon!
Note: Beautiful spirally non-Fibonacci pinecones are very rare! If you find one, keep it!
