Fibonacci Spiral - Golden Spiral Logarithmic spiral whose growth factor is φ…

"The Golden Mean is represented by the Greek letter phi, (with the decimal representation of 1.6180...) is one of those mysterious natural numbers that seems to arise out of the basic structure of our cosmos. Phi appears regularly in the realm of things that grow and unfold in steps just as the Nautilus shell grows larger on each spiral by phi."

FibonacciCurve2_house...Fibonacci 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, ... Fibonacci, Golden Ratio, Phi and Divine Proportion. Adjacent numbers quickly approach a constant ratio equal to the "golden ratio" ϕ (approximately 1.618). Worth noting: ϕxϕ = ϕ + 1 and 1/ϕ = ϕ - 1 Also note floral spiral pattern: 137.5° + 222.5° = 360° and 222.5/137.5 = ϕ ≅ 1.618
