DESCRIPTION:
Now, Martin Bojowald explains the science behind this new model of the universe in a step-by-step argument for the logical and philosophical cogency of loop quantum gravity (with fascinating digressions into art, literature, and philosophy), and in the process takes us on a remarkable journey through the history of modern cosmology, back to the origin of the universe and to the time before it existed. In Martin Bojowald, we have not just an extraordinary and rigorous scientific mind, but also a science writer of uncommon eloquence and accessibility whose subject is as thoroughly fascinating as it is revolutionary.. In 2000, Martin Bojowald, then a 27-year-old postdoc at Pennsylvania State University, used a relatively new theory called loop quantum gravity - a combination of Einstein's theory of gravity and quantum mechanics - to create a simple model of the universe. According to LQC, our universe could have emerged from the
"RSC" according to Roderick S. Cowley. Reasonably well written by an active cosmologist familiar with the latest ideas on loop quantum gravity and cosmology. Although the mathematics is not presented (apparently even world-class mathematicians have difficulty understanding the math), the presentation requires a significant effort on behalf of the reader to understand the concepts. Worth the effort though. Flex your mind.. time unravelled R. A. Bull This is a semi-popular discussion of loop quantum gravity and its applications to black holes and cosmology. Although avoiding the formulas and equations which so discomfort some folk, it requires a reasonable familiarity with modern physics.The book opens with introductions to gravity and quantum theory, giving a particularly interesting account of general relativity, using the GPS as an example. These themes combine in the central chapter describing loop quantum gravity, a candidate 'theory of everything'. Essentially it is a quantum version of Ashtekar's formulation of.
