Recent advances in our understanding of instabilities in galactic
type systems have led to an unravelling of some of the mysteries of
what determines the form galaxies take. This book focuses on the
mathematical development of the subject, assuming no prior
knowledge of it, with a strong emphasis on the underlying physical
interpretation. This framework is used to discuss the most relevant
instabilities which are believed to be closely involved in the way
galaxies are formed, in a model independent manner. The relevant
observed properties of galaxies that may be used to establish the
role of these physical mechanisms are discussed. The book also
includes a chapter discussing numerical simulation techniques, with
attention paid to their limitations and to recent advances in this
approach. It is demonstrated that recent developments in computer
hardware enable a detailed comparison of simulations with analysis.
Thus the simulations extend our physical understanding beyond the
limitations of the analysis. The book is intended for use by
postgraduate students and researchers in the areas of cosmology,
extragalactic astronomy and dynamics.

From the reviews:
"It survives the pitfalls of this fashion-conscious era by pursuing
a rigorously independent-minded attitude to contemporary ideas. The
level is introductory undergraduate, with rather little mathematics
but a strong physical basis.
...The second part, on general relativity and cosmology, provides a
good account of modern theoretical ideas, from rotating black holes
to Grand Unified Theories and inflation. The third part is an
excellent and profound discussion of the fundamental problems of
cosmology. For anyone with a philosophical turn of mind this
section alone makes the book essential reading." Nature
