In mathematics, two quantities are in the [[Golden Ratio]] if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. [[ | In mathematics, two quantities are in the [[Golden Ratio]] if their ratio is the same as the ratio of their sum to the larger of the two quantities. The figure on the right illustrates the geometric relationship. The [[Golden Ratio]] based spirals, [[Fibonacci]] spirals, and [[Golden Spiral]]s often appear in living organisms. The Golden Ratio is also found in geometry, appearing in basic constructions of an equilateral triangle, square and pentagon placed inside a circle, as well as in more complex three-dimensional solids such as [[Platonic Solids|dodecahedrons]], [[Platonic Solids|icosahedrons]] and [[Buckyballs]]. | ||
There is a special relationship between the [[Golden Ratio]] and [[Fibonacci]] Numbers (0, 1, 1, 2, 3, 5, 8, 13, 21, ... etc, each number is the sum of the two numbers before it). When we take any two successive [[Fibonacci]] Numbers, one after the other, their ratio is very close to the [[Golden Ratio]]. This is called an approximation or limit value in calculus. | There is a special relationship between the [[Golden Ratio]] and [[Fibonacci]] Numbers (0, 1, 1, 2, 3, 5, 8, 13, 21, ... etc, each number is the sum of the two numbers before it).
