Marion shows that study of Wittenstein's writings on mathematics is essential to a proper understanding of his philosophy

A text aimed at third year undergraduates and graduates in mathematics and physics, presenting elementary twistor theory as a universal technique for solving differential equations in applied mathematics and theoretical physics.

There is a continuing growth of interest in the computer simulation of materials at the atomic scale, using a variety of academic and commercial computer programs. Such programs work with very diverse models of the inter-atomic forces. This book explains how such models are constructed, their scientific basis and the approximations that must be made in deriving them.

Quantum Mechanics is a comprehensive introduction to quantum mechanics for advanced undergraduate students in physics.

This book provides an introduction to some of the most recent developments in string theory, and in particular to their mathematical implications and their impact in knot theory and algebraic geometry.
