Squares, primes, and proofs
Mathematicians have proved the so-called local Langlands correspondence, a broad generalization of a surprising connection between prime numbers and perfect squares.

Losing to win
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 between the two games.

Fractal Roots and Artful Math
The term “mathematical art” usually conjures up images of M.C. Escher’s endless staircases, Möbius-strip ants, and mind-boggling tilings. Or it might remind one of the intimate intertwining of mathematics and art during the Renaissance with the development of perspective painting and eye-teasing stagecraft. A view of the recent MathArt/ArtMath show at the Selby Gallery in […]

Candy for Everyone
Several students are sitting in a circle. Each student has an even (though not necessarily the same) number of wrapped pieces of candy. On a signal, each student passes half of his or her trove to the student on his or her right. Between signals, the teacher (reaching into an inexhaustible goody bag) gives any […]

A Stranger from Spaceland
“It was the last day of the 1999th year of our era. The pattering of the rain To a Flatlander, a sphere passing through Flatland appears as a line of changing length. had long ago announced nightfall; and I was sitting in the company of my wife, musing on the events of the past and […]

Setting Records Randomly
A wide variety of factors can influence the winning time of a race. For a given event over the course of a year, for example, the results may depend on the quality of the runners, the race location, weather conditions, and so on. In a 1985 article in the Journal of the American Statistical Association, […]

Crystal Möbius
Take a ribbon of paper, twist one end 180 degrees, and attach it to the other end. The resulting surface, called a Möbius strip, has only one side and one edge. Scanning electron microscope image shows niobium selenide crystals in a Möbius-strip conformation (top). In the schematic diagram (bottom), a white ribbon represents a niobium […]

Prime Effort: Powerful conjecture may be proved
A mathematician may have finally proved Catalan's conjecture, a venerable problem in number theory concerning relationships among powers of whole numbers.

A Lawyer’s Math Library
“Strangely enough, anyone wishing to write about Galois in Paris would do well to journey to Louisville, Kentucky.”–Leopold Infeld, Whom the Gods Love LOUISVILLE, KY. French mathematician Evariste Galois (1811–1832), whose death in a duel at the age of 20 cut short a remarkably productive career, is only one of many mathematicians represented in a […]

Song-and-Dance Fermat
The proof of a mathematical conjecture–even one as famous as Fermat’s last theorem–may sound like an improbable subject for an off-Broadway-style musical. Yet there’s plenty of drama and passion in the story of Fermat’s last theorem. These elements take center stage in Fermat’s Last Tango, a musical written by the husband-and-wife team Joshua Rosenblum and […]

Filling In Blanks
Researchers are developing automated methods based on differential equations to reduce the time and effort required to fix digital images, not only to fill in blank areas but also to remove extraneous objects.
