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.

Wikimedia Foundation Inc.’s popular

Wikipedia

online encyclopedia cracked the top ten list of most popular Web sites in the U.S. for the first time in January, according to comScore Networks Inc.
Wikipedia sites ranked ninth with 42.9 million unique visitors last month, ahead of the sites from The New York Times (number 10), Apple Inc. (number 11) and Viacom International Inc. (number 12), comScore reported Thursday.

Wikipedia, which already ranked in the top ten list of most popular Web sites globally, has been quickly gaining popularity in the U.S., where its parent company, the non-profit Wikimedia Foundation, is based.

In January of last year, Wikipedia sites ranked in the 33rd spot with 18.3 million unique visitors. By July, it had climbed to the 18th spot on the list with 28.1 million unique visitors, and in November it ranked 12th with 39.1 million unique visitors, according to comScore.

In doing its tally for Wikipedia, comScore also counts visits to other Wikimedia sites, like Wiktionary, Wikiquote, Wikibooks and Wikinews, but most of the traffic comes from the Wikipedia encyclopedias, a comScore spokesman said.

Wikipedia started in January 2001 with its English-language site, which currently has more than 1.6 million articles. The Wikipedia project has since grown significantly and has more than 5 million articles in more than 200 languages, according to WikiMedia. Access to Wikipedia is free. Volunteers contribute the encyclopedia’s content, which can be edited by anyone accessing the sites.

Globally, Wikipedia sites ranked sixth in December with almost 165 million unique visitors, according to comScore.

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

Capture HDTV using your firewire-equipped cable box

25 01 2007

According to FCC regulations, all DVRs that cable companys rent must have an active firewire port. While unfortunately you likely won’t be able to record premium channels such as HBO, INHD, DiscoveryHD. All broadcast channels must be open. If any broadcast channels are encrypted a quick call to your cable company will fix this. This is a dream come true for all you TV archivers.
While I use this method primarily for recording 720p, and 1080i HDTV sources, this will work for standard definition digital channels as well.
