In one way or another, these and many more creations of nature or works of man all seem to be related to a sequence of numbers named for 13th century Mathematician Leonardo Fibonacci. The earnest mathematics buffs of the California-based Fibonacci Association keep examining the phenomenon. The more they investigate, members insist, the more convinced they become that Fibonacci numbers pervade the world...
...intriguing sequence was first mentioned by Fibonacci in his book Liber Abaci, which was published in Pisa in A.D. 1202.

Fibonacci attached no great significance to the sequence, and it was generally ignored through the years by all but dedicated mathematicians. Then, in the early 1960s, Brother Alfred Brousseau, who teaches math at St. Mary's College...
Golden Rectangle. There is more than enough Fibonacci lore to fill each issue. "We have a backlog of articles," says Brother Alfred proudly, "and we've been accepted by the mathematical fraternity." Mathematician Verner Hoggatt Jr., editor of the Quarterly, has gone to the extent of establishing the Fibonacci Bibliographical and Research Center at San Jose State College. He tours schools to lecture on Fibonacci numbers, vigorously advocates their use in teaching and has compiled a remarkable dossier on Fibonaccia...
