The amazing Fibonacci numbers were first applied in which field (trading, architecture, running tracks, gambling)?

I'd say ARCHITECTURE The Fibonacci sequence first appeared as the solution to a problem in the Liber Abaci, a book written in 1202 by Leonardo Fibonacci of Pisa to introduce the Hindu-Arabic numerals used today to a Europe still using cumbersome Roman numerals. The original problem in the Liber Abaci asked how many pairs of rabbits can be generated from a single pair, if each month each mature pair brings forth a new pair, which, from the second month, becomes productive. The Fibonacci numbers are found to have many relationships to the Golden Ratio F = (1 + /5)/2, a constant of nature and a value which fascinated the ancient Greeks, appearing throughout Greek art and architecture. One can verify with a hand calculator that the ratio of Fn+1 to Fn is approximated by 1.6180339..., which is the decimal equivalent of the Golden Ratio. http://www.cs.rit.edu/~pga/Fibo/fact_sheet.html Apr 20 03, 11:29 AM
