This textbook treats solids and fluids in a balanced manner,using thermodynamic restrictions on the relation between appliedforces and material responses. This unified approach can beappreciated by engineers, physicists, and applied mathematicianswith some background in engineering mechanics. It has many examplesand about 150 exercises for students to practise. The highermathematics needed for a complete understanding is provided in theearly chapters. This subject is essential for engineers involved inexperimental or numerical modelling of material behaviour.
Designed to be the essential reference works for all readersand students, these volumes present the most thorough analysispossible of Tolkien's work within the important context of hislife.

Quantum gravity is one of the major open problems in theoreticalphysics. The loop and spinfoam approach, presented in this book, isa leading research program in the field. Emphasis is given toconceptual and foundational issues raised by quantum gravity,especially on the nature of space and time. This text is intendedfor researchers working in quantum gravity and, in particular,graduate students entering the field. It will also appeal tophilosophers and scientists interested in the general issue of thenature of space and time.
