This second edition to the bestselling Quantum Gravity in a Nutshell1 is a good introduction to quantum gravity and has a lot of interesting history about the development of the theory since 1899. It's an informal introduction to a very difficult and doubtfully intelligible theory.- doubted even by its most ingenious contributors. The reader should expect that he/she will have to concentrate hard on what Balungi says but the rewards are significant. He is a talented physicist and a good writer. If you read it carefully and stop to think about the message as it unfolds then you will get a worthwhile if imperfect picture of what the theory is saying and how it was invented, It's buried treasure and you will have to do some digging. It is a really serious attempt to do all that can be done in an informal style. Balungi explains and re-defines Einstein's theory of general relativity, quantum mechanics, black holes, the complex architecture of the universe, elementary particles, gravity, and the nature of the mind. This wonderful and exciting book is optimal for physics graduate students and researchers. Not since Stephen W Hawking's celebrated best-seller Brief History of Time has physics been so vividly, intelligently and entertainingly revealed.

In 1900, the British physicist Lord Kelvin declared "There is nothing new to discover in physics. All that remains is to more accurately measure its quantities" today, hardly anyone would dare say that our knowledge of the universe and everything in it is almost complete. There are still some deficiencies in the standard model of physics, such as the origin of mass, the strong CP problem, neutrino oscillations, matter-antimatter asymmetry and the nature of dark matter and dark energy. Another problem lies within the mathematical framework of the standard model itself. Some of the major problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomena or experimental result. The others are experimental meaning that there is difficulty in creating an experiment to test a proposed theory. In what follows, there is given a discussion of what are arguably the most unsolved problems in physics, astrophysics and cosmology. And this book sets to solve them living none untouched. The form of the discussion is not negative: formulating a problem succinctly is essential to a solution. Perhaps the most remarkable aspect of what follows is that many of the problems are interrelated, so the solution of one or a few opens the prospect of widespread advancement. An excerpt from Lee Smolin's book "the trouble with physics" explains in detail what this book is all about as given below in Lee's original words. To be fair we've made two experimental discoveries in the past few decades, that neutrinos have mass and that the universe is dominated by a mysterious dark energy that seems to be accelerating its expansion. But we have no idea why neutrinos (or any other particles) have mass or what explains their mass values. As for dark energy, its not explained in terms of any existing theory. Its discovery cannot then be counted as a success, for it suggests that there is some major fact we are all missing. And except for dark energy, no new particle has been discovered, no new force found, no new phenomenon encountered that was not known and understood twenty-five years ago. Don't get me wrong. For the past 25years we have certainly been very busy. There has been enormous progress in applying established theories to diverse subjects; the properties of materials, the molecular physics underlying biology, the dynamics of vast clusters of stars. But when it comes to extending our knowledge of the laws of nature we have made no real head way. Many beautiful ideas have been explored, and there have been remarkable particle aaccelerator experiments and cosmological observations, but these have mainly served to confirm exisiting theory. There have been few leaps forward, and none as definitive or important as those of the previous 200years. When something like this happens in sports or business, it's called hitting the wall. What are the major unsolved problems in physics? And what can we do to solve them? These are the central questions of my book

The essential introduction to modern string theory—now fully expanded and revised String Theory in a Nutshell is the definitive introduction to modern string theory. Written by one of the world’s leading authorities on the subject, this concise and accessible book starts with basic definitions and guides readers from classic topics to the most exciting frontiers of research today. It covers perturbative string theory, the unity of string interactions, black holes and their microscopic entropy, the AdS/CFT correspondence and its applications, matrix model tools for string theory, and more. It also includes 600 exercises and serves as a self-contained guide to the literature. This fully updated edition features an entirely new chapter on flux compactifications in string theory, and the chapter on AdS/CFT has been substantially expanded by adding many applications to diverse topics. In addition, the discussion of conformal field theory has been extensively revised to make it more student-friendly. The essential one-volume reference for students and researchers in theoretical high-energy physics Now fully expanded and revised Provides expanded coverage of AdS/CFT and its applications, namely the holographic renormalization group, holographic theories for Yang-Mills and QCD, nonequilibrium thermal physics, finite density physics, and entanglement entropy Ideal for mathematicians and physicists specializing in theoretical cosmology, QCD, and novel approaches to condensed matter systems An online illustration package is available to professors
