The 24 major island groups of the Pacific Ocean were settled by early Austronesians between 3,500 and 900 years ago, but little is known about how these isolated islands were colonized. Now, researchers have used epidemiological modeling to devise some compelling new ideas about how it was done.

Young chickens, it seems, also map numbers from… » 1/30/15 10:40am 1/30/15 10:40am

How To Prove A Geometric Formula With A Clementine And A Piece of Paper

Here's a fun demonstration from Cornell maths professor Steven Strogatz. Take a clementine (or any spherical, peelable fruit) and trace around its widest part four times. Then peel it. Flatten out the peelings as best you can and divvy them up evenly among the circles. Voilà! Tangible proof that the the surface area… » 1/14/15 4:50pm 1/14/15 4:50pm
