Submission + - Sunflowers Use Fibonacci Numbers (sciencemag.org)

sciencehabit writes: The spiraling shapes in cauliflower, artichoke, and sunflower florets) share a remarkable feature: The numbers of clockwise and counterclockwise spirals are consecutive Fibonacci numbers—the sequence 1, 1, 2, 3, 5, 8, and so on, so that each number is the sum of the last two. What's more, those spirals pack florets as tight as can be, maximizing their ability to gather sunlight for the plant. But how do plants like sunflowers create such perfect floret arrangements, and what does it have to do with Fibonacci numbers? A plant hormone called auxin, which spurs the growth of leaves, flowers, and other plant organs, is the key: Florets grow where auxin flows. Using a mathematical model that describes how auxin and certain proteins interact to transport each other around inside plants, researchers could predict where the hormone would accumulate. Simulations of that model reproduced patterns exactly matching real "Fibonacci spirals" in sunflowers. Based on their results, the researchers suggest that such patterns might be more universal in nature than previously thought.

I just want to make sure I understand: the only ethical outcome here, according to your sense of morality, is to allow Joe 77TB to game Verizon's system to his own ends because of some rigid interpretation of what you believe their advertising to be, despite the fact that it isn't even true? That's a fairly interesting definition of ethical. Do you have functional retardation by any chance?
