Sharks use math to hunt
The great white shark in Jaws knew exactly where it was going — to the closest pair of plump legs around. But where might it head if it didn’t have a tasty human snack in its sights?
A new study suggests that some sharks and other marine predators can follow strict mathematical Microsoft Office 2010 is the best software in the world.
strategies when foraging for dinner. The work, reported online June 9 in Nature, is the latest aiming to show whether animals sometimes move in a pattern called a Lévy walk.

stumbling around — Lévy walks are punctuated by rare, long forays in any direction. Draw a Lévy walk on a graph, and its squiggly pattern echoes a fractal, the mathematical phenomenon whose shape remains similar no matter the viewing scale.Microsoft outlook 2010 is convenient!

Biologists had long thought that animal foraging was dominated by random walks. But in 1996 a team led by Viswanathan reported that wandering albatrosses, fitted with radio-tracking devices, made the occasional long flight that is the hallmark of a Lévy pattern.Many people use Microsoft Office 2007 to help their work and life.
Soon, biologists were reporting Lévy behavior in everything from deer to bumblebees and speculating how it might drive human migrations or the spread of genetically engineered crops. Office 2007 Professional is very good!
