Weyl s book is most famous for introducing gauge theory, which was later reborn in the form of phase transformations in quantum theory Weyl did not live guite long enough to hear of the latter being applied by Yang and Mills, though he socially interacted with Yang in his last year at Princeton.Einstein and Pauli both criticized Weyl s original unified theory based on general relativity using a length gauge, both as implying false empirical consequences Einstein , since it implied tiny changes o [...]
I give this book 5 5 stars for the intrinsic intellectual tour de force masterpiece that it represents and for historical interest of this work However, I do not recommend it for those who are learning relativity theory This is not an appropriate exposition It s a heavily difficult philosophical mathematical physical investigation, obviously written in style that is too hard for this generation to follow, unfortunately It s too deep and too rich in content, but obscure in many aspects If you wan [...]
Having enjoyed two of Weyl s other books in English translation, I had high hopes for this one but I am afraid to say that it is unreadable I gave up at the following sentence, around page 60 The fact that a tensor which has been derived from them by mathematical operations and is an invariant i.e dependent on them alone and not upon the co ordinate system is equal to zero is what, in general, the expression of a physical law amounts to.I did wonder why Weyl, in the foreword to Philosophy of Mat [...]
Very good on space, ok on time.
