## 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.

## Adaptive Networks in Action: Opinion Formation, Epidemics and the Evolution of Cooperation

The authors provide an overview and give some examples from the emerging field of adaptive networks, where the structure of a network changes in response to an underlying model.

## 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.

## Models in Applied Math and Beyond

### A range of meanings for the word "model"

When scientists talk about developing models as part of their research, they can refer to quite different things.  Even within industrial and applied mathematics, modeling can have a variety of meanings. To avoid confusion and clearly communicate the relevance of mathematical modeling, it's important to understand what those different meanings are.
