The following is from: http://evolutionoftruth.com/div/fibomyst.htm
*Fibonacci, Phi and Spirals in Nature
If you sum the squares of any series of Fibonacci numbers, they will equal the last Fibonacci number used in the series times the next Fibonacci number.
*DNA
The DNA molecule, the program for all life, is based on the golden section. It measures 34 angstroms long by 21 angstroms wide for each full cycle of its double helix spiral.
Construction of the golden section DNA and the golden section
34 and 21, of course, are numbers in the Fibonacci series and their ratio, 1.6190476 closely approximates phi, 1.6180339.
Plus to calculate Phi:
5 ^ .5 * .5 + .5 = Ø (Phi)
2 + 1^2 + 2^2 + 3^2 + 5^2 = 5 x 8
therefore:
1^2 + 1^2 + . . . + F(n)^2 = F(n) x F(n+1)
Also phi (.618) is one of the few numbers where:
x^2 = x + 1
(.61803399)^2 = (.61803399) + 1 = 1.61803399
Ever hear of this before? Seen it before?
