A little diversion for you, today. I took the featured pictures yesterday up at the edge of the high heath.
Dull and cold all day.
This is an Ox-Eye Daisy. Count the petals.
This is a close-up of the centre of the daisy. Count the spirals (highlighted in black).
Interesting?
The Fibonacci series is the following set of numbers:-
0,1,1,2,3,5,8,13,21,34,55,89....and so on.
To get the numbers in the Fibonacci series, we write down the two numbers 0 and 1, and then add them together, giving 1. Then we add the 1 and the 1 giving us 2. Each number in the Fibonacci series is obtained by adding the two previous ones together.
Notice that the number 21 is a Fibonacci number.
Not all flowers have numbers of petals that appear on the Fibonacci series, but many do. Some will be just under a Fibonacci number, or just over, but their average will usually be one of the series.
Yesterday's Sow-Thistle appears to have very close to 34 of the larger outside petals.
