Presentation by Ann Maslen

Fibonacci! What do pineapples, sunflower head seeds, nautilus shells, Pinecones, cabbages and wave sequences have in common?

Ann explained the mathematical sequence favoured by evolution - the secret patterns of nature known as the Fibonacci ratio.
The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. Starting with 0 and 1, the sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so forth.

On many plants, the number of petals is a Fibonacci number:
buttercups have 5 petals; lilies and iris have 3 petals; some delphiniums have 8; corn marigolds have 13 petals; some asters have 21 whereas daisies can be found with 34, 55 or even 89 petals.
