The Nature of Fibonacci Numbers
By Dick Yeatts, PhD, Colorado School of Mines, Golden, CO
The sequence of numbers 1,1,2,3,5,8,13,..., wherein each number is the sum of the preceding two, is credited to Leonardo of Pisa (a.k.a. Fibonacci). The remarkable properties of these numbers and their progeny, the "golden" ratios, find application in nearly every field of human endeavor including art, music, economics, and geometry. In the life sciences, the numbers relate to such diverse subjects as human anatomy, snail shells, and the architecture of plants.

F. R. (Dick) Yeatts is a Professor Emeritus in Physics at the Colorado School of Mines. While employed, his research was mostly in geophysics. Since retiring, his interest is in the mathematics and physics of plants.
