## Dynamics of Voter Models on Simple and Complex Networks

Sidney Redner discusses how groups of people reach consensus using voter models on networks.

## Interview with Nancy Kopell

We interviewed Nancy Kopell, the winner of SIAM’s 2013 Jürgen Moser Lecture prize for her lifetime contributions in applied dynamical systems, about mathematics, her career, current frontiers in mathematical neuroscience, and more. Nancy is a professor at Boston University in the Department of Mathematics & Statistics, is Director of their Cognitive Rhythms Collaborative, and is Co-Director of the Center for Computational Neuroscience & Neural Technology. Nancy has won numerous awards and made pioneering contributions to dynamical systems, mathematical neuroscience, and mathematical biology more generally. Take a look at her website and her Society for Neuroscience biography for more details.

## Interview with Masato Nagata

In 1990, Masato Nagata published the first ever computation of fully nonlinear, finite-amplitude invariant solutions in planar Couette flow. In his paper, he mixed dynamical systems theory, fluid dynamics and computational science, and it has garnered nearly three hundred citations over the years and has had an enourmous impact on the analysis of turbulence as a dynamical system. In this interview, Prof. Nagata shares some of the long, arduous and occasionally joyful journey to this landmark contribution.

## Mathematics on the Chopping Block

The production of end-grain wooden cutting boards involves repeated operations
that lead to interesting mathematical questions. I explore some of the mathematical issues that arise in the process; they pose some interesting mathematical puzzles. I also show how mathematics can be used to create
intricate artistic designs for cutting boards that are amenable to
woodworking. These designs have been tested in real wood. Some of them belong
to a class of iterated-function-system fractals but others do not. The
overall goal is to produce an aesthetically pleasing design suggested by
mathematics and implementable in wood.
