DESCRIPTION:
"Provocative, original, and unsettling." -The New York Review of Books"An excellent writer, a creative thinker."-Nature . "It would be hard to imagine a better guide to this difficult subject."--Scientific AmericanIn Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand
I am falling in love with my life said A Gentle Introduction to Loop Quantum Gravity. Quantum mechanics and general relativity are great, but they are known to be hardly merged into one theory. But if there is a unified theory that describes nature, they should be. Physicists believe in such a unified theory. So there have been a lot of efforts to unify them, and physicists call the unified theory quantum gravity. According to the book, "Three Roads. Certainly Helpful, Not Stellar I am an amateur student of theoretical physics, having read and loved the books Cosmos, A Brief History of Time, Black Holes and Time Warps and The Elegant Universe. Having taken a year of calculus and a year of physics in college (ages ago), I have had some limited academic exposure to a few of the ideas described in these books. I was looking forward to reading L. A fair summary of the status of research in quantum gravity Considering the experimental status of theories of quantum gravity, it is remarkable that research in this area has progressed to the level in which it has in the last few decades. If one examines the history of science it is readily apparent that laboratory and observational data drove the most successful scientific theories. By reading this book and by perusing s
--Gregory McNamee. It's more difficult still given some of the contradictions and inconsistencies that obtain between quantum theory, which "was invented to explain why atoms are stable and do not instantly fall apart" but has little to say about space and time, and general relatively theory, which has everything to say about the big picture but tends to collapse when describing the behavior of atoms and their even smaller constituents. Although he allows that "it has not been possible to test any of our new theories of quantum gravity experimentally," Smolin predicts that a solid framework will be established by 2015 at the outside. If he's correct, the
