On the back of reading a brief history of time this book looked like an interesting read. In some ways it has the same aims as the older book but does not shy quite so far away from any mathematical treatment. That said the maths it presents is fairly basic, little enough not to scare away but enough to make you want to know more if you are so inclined.
This book did make me think more about the time dilation effects of spacetime, something I had not properly appreciated before. Also the discussion of invariants and wanting to do physics with equations that are invariant for all observers.
There is a more up to date treatment of the fundamental particles, and more coverage of the mass energy equation.
Finally the standard model is presented and the missing link goes on into the discussion of the LHC and what it hopes to reveal.
