The physics of condensed matter in contrast to quantum physics or cosmology is not
traditionally associated with deep philosophical questions. However as science - largely
thanks to more powerful computers - becomes capable of analysing and modelling ever more
complex many-body systems basic questions of philosophical relevance arise. Questions about
the emergence of structure the nature of cooperative behaviour the implications of the second
law the quantum-classical transition and many other issues. This book is a collection of
essays by leading physicists and philosophers. Each investigates one or more of these issues
making use of examples from modern condensed matter research. Physicists and philosophers alike
will find surprising and stimulating ideas in these pages.
