Quantum Gravity(ISBN=9780521837330)

Quantum gravity is one of the major open problems in theoretical physics. The loop and spinfoam approach, presented in this book, is a leading research program in the field. Emphasis is given to conceptual and foundational issues raised by quantum gravity, especially on the nature of space and time. This text is intended for researchers working in quantum gravity and, in particular, graduate students entering the field. It will also appeal to philosophers and scientists interested in the general issue of the nature of space and time.
