…and they way they move, ScienceDaily says follows the same mathematical pattern:

A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led by University of Arizona anthropologist David Raichlen, was published [...]

Nature has more on the math whizzes of the South Pacific:

Binary arithmetic, the basis of all virtually digital computation today, is usually said to have been invented at the start of the eighteenth century by the German mathematician Gottfried Leibniz. But a study now shows that a kind of binary system was already in use 300 years earlier [...]

That’s the argument Laboratory Equipment describes some mathematical taxonomists (there’s a discipline for you) are making – claiming that some kinds of plankton are individually so small and so *weird*, they’re impossible to divide into different species:

A new mathematical theory from the Univ. of Bath is challenging one of the most basic ideas of biology: that the concept of [...]

SONG: “Beautiful People” (penitential cover) (To download: double right-click & “Save As”)

ARTIST: grant.

SOURCE: This is a cover (a late one) making up for a late song in April. Now, I owe one more cover for May. Mea maxima culpa. This song was written by the curiously academic and oddly moving Books.

ABSTRACT: I was searching for [...]

This is an illustration of a model of a paradox – they hydrostatic paradox, as demonstrated by Blaise Pascal. The paradox is that the pressure at the bottom of a column of water only depends on the height of the water, not the shape or the volume. Six tons of water and six ounces of water will [...]

Nature looks at the star power of “network theory,” curious statistics that control all kinds of complicated systems. They’ve found that even really complex networks are shaped by an influential few:

To demonstrate their technique, Yang-Yu Liu of Northeastern University in Boston and his colleagues looked at the entire human metabolic network and found that concentrations of about 10% [...]

MIT Technology Review crunches the numbers and figures that anyone who spends three years on Mars is going to witness an H-bomb-sized asteroid collision:

Today. William Bruckman and pals at the University of Puerto Rico at Humacao do exactly this kind of analysis but with a twist. They derive impact probabilities for Earth but also for Mars. Their conclusion [...]

Science Art: <i>Jungle Allure</i> by Diane Walker

This painting was one of the winners of the Benoit Mandelbrot Fractal Art Contest 2007, a mathematical art contest.

I suppose nowadays, fractal art seems very, very 1990s. But still – there’s something fun and dreamlike about it.

As Dr. Mandelbrot himself says in his introduction to the gallery:
“What distinguishes fractal geometry within mathematics is an exceptional and [...]
