Philip J. Davis reminisces about Mary Cartwright from the perspective of a decades-long friendship, appreciating her especially for a ``mind and a tongue sharpened over the years by the repartee of Oxbridge high table wits.'' The article appears in SIAM News, Volume 31(6), July/August 1998, 4.
UK Nonlinear News ran a news item on Topological Methods in ODE's: The Mathematical Collaboration of M.L. Cartwright and J.E. Littlewood in a previous issue.
In 1948, the world's first stored-computer performed its first (dramatic) computation at the University of Manchester; this Spring, researchers gathered at Manchester to celebrate 50 years of progress in computers and numerical analysis

The lead article in SIAM News 31(7) is a report on this conference, co-sponsored by the UK and Republic of Ireland (UKIE) SIAM Section. Slides from some of the talks and photographs are available at http://www.ma.man.ac.uk/NAC98".
In Notices of the American Mathematical Society 45(9), October 1998, pages 1120-1123, John Guckenheimer discusses the need for a broadening in the scope of the mathematical theories that provides the foundations for the analysis of computer simulations. Many of the scientific problems that computer simulation are increasingly been used for are not readily modelled using the approach that has been so successful in dealing with fluid mechanics. New mathematical theories are required in order to ensure that these complex problems can be tackled efficiently.
Guckenheimer discusses five issues that will present challenges to twenty-first century mathematics:
ABSTRACT. The decimal expansion of real numbers, familiar to us all, has a dramatic generalization to representation of dynamical system orbits by symbolic sequences. The natural way to associate a symbolic sequence with an orbit is to track its history through a partition. But in order to get a useful symbolism, one needs to construct a partition with special properties. In this work we develop a general theory of representing dynamical systems by symbolic systems by means of so-called Markov partitions. We apply the results to one of the more tractable examples: namely, hyperbolic automorphisms of the two dimensional torus. While there are some results in higher dimensions, this area remains a fertile one for research.

ABSTRACT. This is a report on recent work of Robert Ghrist in which he shows that universal templates exist. Put another way, there are many structurally stable flows in the 3-sphere, each of which has periodic orbits representing every knot type. This answers a question raised originally by Mo Hirsh and popularized by the contrary conjecture by John Birman and the present author.

Nonlinearity now offers multimedia features to authors. The Paper "Bifurcations of periodic orbits with spatio-temporal symmetries" by A.M. Rucklidge and M. Silber published in Nonlinearity 11(5) includes two animations (each in both Animated GIF and MPEG formats) showing alternating rolls in 3-D compressible magnetoconvection.
