"Quantum Gravitation" approaches the subject from the point of view of Feynman path integrals, which provide a manifestly covariant approach in which fundamenta

Quantum theory and Einstein's theory of relativity are at the centre of modern theoretical physics, yet, the consistent unification of both theories is still el

This book describes a paradigm change in modern physics from the philosophy and mathematical expression of the quantum theory to those of general relativity. Th

The relation between quantum theory and the theory of gravitation remains one of the most outstanding unresolved issues of modern physics. According to general

Quantum gravity is perhaps the most important open problem in fundamental physics. It is the problem of merging quantum mechanics and general relativity, the tw
