Description
Book SynopsisThe greatest challenge for physics is to combine its two most successful theories: general relativity and quantum mechanics. The resulting quantum theory of gravity would explain the universe across all scales. Much has been said about the approach based on string theory. Here, Jim Baggott describes its powerful rival: Loop Quantum Gravity.
Trade Review...if you have enjoyed/got through popular science books about such areas as strings and superstrings, time, and the God particle, here is a fine addition to the oeuvre. * Ian Francis, School Science Review *
There is no doubt that Jim Baggott is an excellent popular science writer, and Quantum Space is the first complete and approachable account to a quantum theory that delves deep into the quest to resolve one of the great unanswered problems of modern physics: How can general relativity be made compatible with quantum mechanics? Baggott proposes Loop Quantum Gravity, which in our mind is one of the best explanations for anyone who wants to understand more about our puling universe ... It's a triumph. * All About Space Magazine *
There's no doubt that Jim Baggott is one of the best popular science writers currently active ... [he] has done a huge favour for anyone who really wants to understand modern theoretical physics, giving a much better understanding of this fascinating attempt to deal with a central requirement to explain the workings of our universe. It's a triumph. * Brian Clegg, popularscience.com *
A lucid exposition of loop quantum gravity and the search for the structural space, time and the universe focusing around the work of Lee Smolin and Carlo Rovelli. * David Lorimer, Paradigm Explorer *
The discovery and development of Loop Quantum Gravity has been a great adventure. Jim's story beautifully captures its insights and excitement. * Carlo Rovelli, author of Seven Brief Lessons on Physics *
