A D M Walker A. D. M. (David) Walker is the author of Pawns in a Larger Game, a study of the history of the eastern frontier of the Cape Colony. Apart from this, his first venture into history, he is also the author of two research monographs and many scientific papers in space physics.
He is Professor Emeritus in Physics at the University of KwaZulu-Natal in Durban, South Africa.
He lives with his wife in Durban, South Africa, and divides his time between research in space physics, investigating his roots in the Eastern Cape Province, and visiting his grandchildren in New York, Cape Town, and Glasgow.

Pawns in a Larger Game

is the result of more than five years research in a number of institutions including:

Plasma Waves in the Magnetosphere

Plasma Waves in the Magnetosphere

The theory of waves in plasma is developed and applied to various wave phenomena in the magnetosphere. In Part 1 the theory of wave propagation in cold, warm and hot plasmas is developed. Particular attention is paid to the forms of refractive index surfaces, ray surfaces and group velocity surfaces which allow the visualization of the wave fronts which occur under different conditions. There is a full treatment of the interaction between waves and particles. These treatments are copiously illustrated in an attempt to give the reader an intuitive feel for the nature of the phenomena. In Part 2 the theory is applied to a variety of natural wave phenomena which occur in the magnetosphere.

MHD Waves in Geospace

Magnetohydrodynamic Waves in Geospace

Solar-terrestrial physics deals with phenomena in the region of space between the surface of the Sun and the upper atmosphere of the Earth, a region dominated by matter in a plasma state. This area of physics describes processes that generate the solar wind, the physics of geospace and the Earth's magnetosphere, and the interaction of magnetospheric processes with the upper atmosphere. Such processes are important for energy transfer between the Sun and the terrestrial environment. Many of these processes are mediated by long period wave phenomena, which are usually treated by magnetohydrodynamic methods.

Magnetohydrodynamic Waves in Geospace: The Theory of ULF Waves and Their Interaction with Energetic Particles in the Solar-Terrestrial Environment provides the theoretician and experimentalist with a coherent account of the important theoretical ideas that underpin current understanding of ultra-low-frequency wave phenomena in solar-terrestrial physics, and that may be used to address future problems. Brief accounts of observational results are included, as well as appendices describing some key mathematical techniques and magnetic field properties in detail

Written in a concise and clear manner, this book will prove valuable reading for advanced graduate students while active researchers in space plasma physics, solar physics, geophysics, planetary science, and astrophysics in need of a source of detailed information will also appreciate this work.
