To the Memory of Jack K. Hale (1928-2009)

"In the Emory Hospital of Atlanta, in the early morning of December 9, 2009, there passed away a great man, Jack K. Hale -- a founding father of numerous areas of modern dynamics, a noble scholar and teacher, and a mentor and dear friend of many of us around the world."
In this article Jack is commemorated by Yingfei Yi, who also interviewed him in 2003 for DSWeb Magazine.

The Rise, Fall, and Legacy of Catastrophe Theory

The Rise, Fall, and Legacy of Catastrophe Theory

In the 2009 Moser Lecture, titled “Catastrophes, Symmetry-Breaking, Synchrony-Breaking,” Golubitsky surveyed the rise, fall, and legacy of catastrophe theory. In particular, he showed how some of the ideas of catastrophe theory can be applied to study the dynamics of networks.

Crawford prize winners revisited: Björn Sandstede

Crawford prize winners revisited: Björn Sandstede

The Crawford prize is awarded biannually since 2001 at the `Snowbird' conferences by the SIAM activity group on dynamical systems for recent outstanding work on a topic in nonlinear science. In a planned series of articles we invite the winners to write about their mathematical biography, their work, and what they consider important problems in the field of applied dynamical system. This article contains the contribution of the first prize winner Björn Sandstede.

Welcome to academia after 30 years in industry

After 30 years of working at Harwell Laboratory in Oxfordshire, Andrew Cliffe left his position as a Senior Consultant with Serco Assurance for a Professorship at the University of Nottingham. Hinke Osinga asks him about the differences between working in a company and at a university and how he decided on his career path.

Homology: An Idea Whose Time Has Come

Homology: An Idea Whose Time Has Come

Tools from the purportedly abstract field of algebraic topology are finding their way into applied mathematics, and Robert Ghrist of the University of Pennsylvania is helping lead the invasion. Ghrist and colleagues use ideas from homology to solve perplexing problems arising in sensor networks, helping to improve their coverage, robustness, and efficiency.
