This book is a great recount in simple (and elegant) writing about cosmology, quantum theory (more to the point about quantum field theory and string theory)
It's a must for whoever want to get to know what theoretical physics (particle physics, high energy physics, cosmology) is about or for those who even having studied a physics grade have gone for another careers so they have lost whatever feeble knowledge they managed to grasp regarding these subjects
The main thread is fascinating: a scientific debate between the author and Hawking about what happens to the information that falls in a black hole... it's re - expelled along with the so called Hawking radiation or… Read more

This book is not intended to learn quantum mechanics up from scratch.
Nonetheless, the great Dirac made a great job of compiling very slippery concepts in a fes pages. And with a very well built, concise and clear thread of thinking.
If you have passed an undergraduate course in quantum mechanics and want to know how the founders made up all the framework out of empirical results compiled by experimental physicists from the second half oh 18th century on, this is a great book. Perhaps some pages may seem a bit "out of fashion" nowadays (as issues long ago well studied and establishes are brought up) but to see how Dirac goes through the mathematical formalism (with the… Read more
