In mathematics, the Fibonacci numbers form a sequence that after two starting values, each number is the sum of the two preceding numbers.
0, 1, 1, 2, 3, 5, 8, 13, 21 and so on. A tiling with squares whose sides are successive Fibonacci numbers in length gives us the pattern shown.
The Golden Rectangle is defined as a rectangle that can be partioned into a square and a smaller rectangle which has the same aspect ratio of the original rectangle successively. Mathematically a ratio of about 3.2:2. The logarithmic spiral, or the “Spira Mirabilis” created by this ratio are found throughout nature, as in the contours of Nautilus shells or sunflowers.
