POPS The Mathematical Lives of Plants

by Kore7 5-6-2007

The seeds of a sunflower, the spines of a cactus, and the bracts of a pine cone all grow in whirling spiral patterns. Remarkable for their complexity and beauty, they also show consistent mathematical patterns that scientists have been striving to understand. ... Scientists have puzzled over this pattern of plant growth for hundreds of years. Why would plants prefer the golden angle to any other? And how can plants possibly "know" anything about Fibonacci numbers? For the first time, scientists have found convincing biochemical mechanisms responsible for the interlocking spiral growth patterns seen in many plants. (The Romanesco broccoli plant is a striking example.) The video of the experiment with magnetized liquid iron droplets demonstrates how the geometry of such growth could occur in nature.

POPS Stocks tumble...Bush's approval ratings to follow?

Simply making an observation that seems logical to me.
