This volume summarizes the many alternatives and extensions to Einstein's General Theory of Relativity, and shows how symmetry principles can be applied to identify physically viable models. The first part of the book establishes the foundations of classical field theory, provid…
"This is a large book with an abundance of topics. I think it well to present something of a guided tour for the prospective reader. Before that, though, allow a bit of advice from an old hand at learning mathematics and physics. The strict training of many students of mathemati…
"There are few articles which can reasonably be described as epoch-making. Einstein's Zur Elektrodynamik bewegter Körper (1905) is undoubtedly one such; Turing's On Computable Numbers, with an Application to the Entschei- dungsproblem (1936) is undoubtedly another. But standing …
In 1918, Emmy Noether, in her paper Invariante Variationsprobleme, proved two theorems (and their converses) on variational problems that went on to revolutionise theoretical physics. 100 years later, the mathematics of Noether's theorems continues to be generalised, and the phy…
