## The Dynamical Systems Track at ICIAM 2011 in Vancouver

In July of 2011, the semi-annual ICIAM took place in Vancouver, British Columbia in Canada. As part of the mathematical program of ICIAM, the SIAM Activity Group on Dynamical Systems sponsored a track of minisymposia. Evelyn Sander describes some highlights.

## Vortices in Bose-Einstein Condensates: (Super)fluids with a twist

P.G. Kevrekidis, R. Carretero-González and D.J. Frantzeskakis showcase some recent experimental and theoretical work in the coldest temperatures in the universe involving vortices in the newest state of matter: the atomic Bose-Einstein condensates. The remarkable feature that these experiments and associated analysis illustrate is a new kind of classical mechanics'' for vortices, which revisits the integrability of the two-body system and opens up exciting extensions for N-body generalizations thereof.

## Report on SciCADE 2011 at the Fields Institute, Toronto.

SciCADE is a biennial meeting that focuses on numerical methods and software for differential equations, including, but not limited to, ordinary differential equations, partial differential equations, differential algebraic equations, delay differential equations, stochastic differential equations and dynamical systems.
Wayne Enright, Ken Jackson and Bob Russell report on this year's meeting.

## Workshop at BIRS: Localized Multi-Dimensional Patterns

While the whole of the US was facing a sizzling heat wave and Europe was washed away by months of rain, some of us where so lucky to get invited to a workshop at BIRS. Peter van Heijster shares his impressions.

## Math in the Twenty First Century

Carson Chow comments on the past and potential future impact of technology on mathematics.
