Math in nature: The famous Fibonacci sequence, a series of numbers in which each is the sum of the preceding two .), shows up everywhere in nature—in nautilus shells, in pine cones, and now in the structure of cacti.
The Golden ratio (1.618) is found in everything within Nature and the Universe..The whole human body is based on the mathematics of the golden mean... storms...the galaxy...leaves, DNA, music....Everything. The Fibonacci sequence is arrived at by adding the two previous terms of the sequence together to create the next term. video: https://www.youtube.com/watch?v=eYDwWbDhCEg www.catalyzingchange.org
"In the case of tapered pinecones or pineapples, we see a double set of spirals – one going in a clockwise direction and one in the opposite direction. When these spirals are counted, the two sets are found to be adjacent Fibonacci numbers.
