A cosmologist and science writer presents a comprehensive and detailed overview of the most recent attempts to reconcile two opposing theories--Einstein's theory of general relativity and quantum theory--by creating a "theory of everything," which is a revolutionary new theory of space, time, and the universe. 25,000 first printing.

From one of the World's most distinguished scientsits, an elegant and concise presentation of the controversial ideas behind quantum gravity

The Holy Grail of modern physics is the search for a theory of "quantum gravity." It is a search for a view of the universe that unites two seemingly opposing pillars of modern science: Einstein's theory of general relativity, which deals with large-scale phenomena (planets, solar systems and galaxies), and quantum theory, which deals with the world of the very small (molecules, atoms, electrons). In Three Roads to Quantum Gravity, cosmologist and science writer Lee Smolin provides the first concise and accessible overview of current attempts to reconcile these two theories in a final "theory of everything." Other books and articles have painted an incomplete picture by exposing only one of the different approaches, including string theory and loop quantum gravity. Here is the closest anyone has ever come to devising a completely new theory of space, time, and the universe to replace the Newtonian ideas that were the foundation of all science until the beginning of the twentieth century.

Book News
Writing for a general audience, Smolin (physics, Pennsylvania State U.) offers an account of recent scientific progress toward a theory of quantum gravity. He explains recent developments, and tells the stories behind the discoveries of loops, strings, and black holes. As he does, he provides a glimpse at the lives of the scientists involved, disclosing their influences, rivalries, and triumphs. He also describes the current frontiers of the discipline, and the questions that remain unsolved. Annotation c. Book News, Inc., Portland, OR (

Excellent book for the layperson wanting to learn more about quantum gravity. This books covers Superstring - "M" Theory, Blackhole Thermodynamics, and Loop Quantum Gravity which he tries to unify these into a single theory using the Holographic Principle. Certainly mind-bending.
