The Mathematical Lives of Plants

Julie J. Rehmeyer

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.

Each yellow nub in the center of this daisy is actually its own miniature flower, complete with a full set of reproductive organs. The buds form interlocking clockwise and counterclockwise spirals.
Scott Hotton

A surprising number of plants have spiral patterns in which each leaf, seed, or other structure follows the next at a particular angle called the golden angle. The golden angle is about 137.5º. Two radii of a circle C form the golden angle if they divide the circle into two areas A and B so that A/B = B/C.

Disposable organizers, conversions, formulas and SUDOKU!!! http://www.pocketmod.com/

What is a PocketMod?

The PocketMod is a new way to keep yourself organized. Lets face it, PDAs are too expensive and cumbersome, and organizers are bulky and hard to carry around. Nothing beats a folded up piece of paper. That is until now. With the PocketMod, you can carry around the days notes, keep them organized in any way you wish, then easily transfer the notes to your PDA, spreadsheet, or planner.

The PocketMod is a small book with guides on each page. These guides or templates, combined with a unique folding style, enable a normal piece of paper to become the ultimate note card. It is hard to describe just how incredibly useful the PocketMod is. It’s best that you just dive in

Coconuter.

17 01 2007

Hello. Meet David, the Coconuter. You can visit his blog at http://coconuter.blogspot.com/

Originally a catharsis project for a high school psychology class, this assignment for David Eric Poarch turned into quite an entertaining video. Having been booted from a previous catharsis performing team, David was forced to perform solo. He had only a couple of days to come up with an idea and did so at the very last minute. Singing, dancing, and acting to a medley of songs (Britney Spears’ Toxic, Westlife’s Uptown Girl & When You’re Like That, Achy Breaky Heart, Starship’s Nothing’s Gonna Stop Us Now, Disney’s Kiss the Girl, and NSync’s Bye Bye Bye) he made some of the best memories of his life through this unrehearsed and somewhat spur of the moment performance. It turned out to be quite a comical and impressive spectacle, to say the least. David is a half American half Filipino who attended Rice University in Texas for a little more than a year and has dropped out. He is now moving out of the country to become a nomad in the Philippines. He is currently dirt poor and scraping pennies (or centavos) just to buy bare necessities like food and water. He tries to maintain a web site ( http://coconuter.blogspot.c… in order to earn some of his food money. He aspires of hitting it big one day in the Philippines somehow or some way. But for now, he’s just a dirt poor person wandering in a third world country with just some knowledge, talent, and faith to guide the way.





Make pretty stars!!

13 01 2007



I found instructions for these beautiful folded paper stars in an old magazine called The Workbasket. Not only were the directions indecipherable, the picture illustrations were misidentified. Although your first attempt might be a challenge, it’ll be worth it as the final product will impress your friends and family.

Use them to decorate your trees and presents for your holiday party, or hang them from your light fixtures for your New Years Eve bash.
