Lonely Universe
In a universe dominated by a mysterious antigravity force, dubbed dark energy, distant galaxies will eventually recede from each other faster than the speed of light and observers in our Milky Way some 50 billion years from now will see only a handful of other galaxies in the sky.

Golden Blossoms, Pi Flowers
In the head of a sunflower, the tiny florets that turn into seeds are typically arranged in two intersecting families of spirals, one winding clockwise and the other winding counterclockwise. Count the number of florets along a spiral and you are likely to find 21, 34, 55, 89, or 144. Indeed, if 34 floret (or […]

Losing to Win
It’s a gift to born losers. Researchers have demonstrated that two games of chance, each guaranteed to give a player a predominance of losses in the long term, can add up to a winning outcome if the player alternates randomly between the two games. This striking new result in game theory is now called Parrondo’s […]

I’m glad to see that other mathematicians are working on the fair-division problem. The challenge is not so much with the optimizing-allocating procedures or algorithms but with how to explain the process and results in a way that is satisfying, understandable, and binding to the participants without seeming to benefit some distant party, like the […]
