In their simplest form, a sequence of numbers 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 337, 610, 987, 1597, 2584, 4181, 6765, etc., in which each successive number is equal to the sum of the two preceding numbers. The fractional version is 1/1, 1/2, 2/3, 3/5, 5/8, 8/13 . . . . Named after Leonardo Fibonacci (1175-c.1250), an Italian mathematician, they have unusual characteristics with possible applications in botony, astronomy, and psychology, as well as in the arts.
