Later on, mathematicians took up the much more difficult question, can we find a formula for rk(n), the number of ways to express n as a sum of k integral squares? This last question led to some of the most sophisticated mathematics of the 20th century, as did a common generalization of all these questions...Hidden Symmetries of Labyrinths from Antiquity and the Middle Ages
http://www.ams.org/samplings/feature-column/fc-2015-10
The purpose of this column is to point out that the great majority of labyrinth designs share a topological symmetry which, while not obvious, cannot be accidental...Mathematics and Ecology
http://www.ams.org/samplings/feature-column/fc-2015-09
Rather than try to show the huge range of ways that mathematics is assisting biologists in understanding the vast landscape of modern biology, I will take a look at a rather small domain, which offers ways to look at some traditional topics from a novel point of view...Game. SET. Line.

After playing the game for a while, two natural questions appear, which we will explore: "How many cards need to be turned face up to guarantee the presence of a set?" and "What is the probability that the initial twelve cards do not contain a set?"...Sums and Integrals: The Swiss analysis knife

The charm of the formula discovered by him [Euler] and MacLaurin is that it applies to a remarkable assortment of mathematical questions...Math and the Sewing Machine
http://www.ams.org/samplings/feature-column/fc-2015-05
In this column I will explore mathematical aspects of the action of the sewing machine and of the often associated bobbin winder...Mathematical Careers

You don't have to be a 'genius' to enjoy mathematics and have a career in it...The Stable Marriage Problem and School Choice
http://www.ams.org/samplings/feature-column/fc-2015-03
This column will present the game-theoretic results contained in the original Gale-Shapley paper along with Roth's subsequent analysis. Pathak calls the deferred acceptance algorithm "one of the great ideas in economics," and Roth and Shapley were awarded the 2012 Nobel Prize in economics for this work...The Mathematics of the Rainbow, Part II
http://www.ams.org/samplings/feature-column/fc-2015-02
I'll first recall in some detail the steps leading to Airy's formula for the intensity of light in a rainbow, and then say something about how Airy made it possible to compare his theory to experiment...Mathematics and Psychology
http://www.ams.org/samplings/feature-column/fc-2015-01
We will see that mathematics in its own terms and psychology in its own terms have benefited from their interaction with each other...
