Soft cells: Rounded tile shapes echo those found in nature

Tiles that fill two- and three-dimensional spaces with no gaps—including triangles, squares, hexagons, cubes, and other polyhedra—are typically designed with sharp corners and flat faces (straight edges).

Mathematicians model a puzzling breakdown in cooperative behavior

Darwin was puzzled by cooperation in nature—it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game theory to better understand ...

Mathematicians debunk GPS assumptions to offer improvements

The summer holidays are ending, which for many concludes with a long drive home and reliance on GPS devices to get safely home. But every now and then, GPS devices can suggest strange directions or get briefly confused about ...

Generalized splitting-ring number theoretic transform

Number theoretic transform (NTT) is widely recognized as the most efficient method for computing polynomial multiplication with high dimension and integral coefficients, due to its quasilinear complexity.

Study uses topological data analysis to identify voting deserts

In past years, elections in the U.S. have been marked by stories of long waiting lines at the voting polls. Add other barriers, like long commutes and inadequate transportation, and voting can become inaccessible. But these ...

Losing count: The mathematical magic of counting curves

How can you figure out which points lie on a certain curve? And how many possible curves do you count by a given number of points? These are the kinds of questions Pim Spelier of the Mathematical Institute studied during ...
