Covariant Loop Quantum Gravity: An Elementary Introduction to Quantum Gravity and Spinfoam Theory Carlo Rovelli, Francesca Vidotto Quantum gravity is among the most fascinating problems in physics. This introduction is very readable, but as others have stated it does require considerable prior knowledge and facility with QM and GR. It has numerous exercises which are valuable for those using the text for study purposes. Does this book contain inappropriate content? L'approche est à mon avis plus prometteuse et cohérente que celle de la théorie des supercordes. His work is mainly in the field of quantum gravity, where he is among the founders of the loop quantum gravity theory. Beware! But if you are to order this book, you better go with the printed version and not the Kindle one, as will you really find it difficult and bothering reading the mathematical equations, terms, and symbols in their scanned form that appear quite small and faded if not illegible. Reviewed in the United Kingdom on October 12, 2017. He collaborates regularly with several Italian newspapers, in particular the cultural suppl. This book provides readers with a simple introduction to loop quantum gravity, centred on its covariant approach. The last chapters are just touching on Cosmology and scattering, so don't expect anything from them, in concrete terms. This book provides readers with a simple introduction to loop quantum gravity, centred on its covariant approach. May be useful to researchers. Use features like bookmarks, note taking and highlighting while reading Covariant Loop Quantum Gravity: … Ainsi le volume et l'aire prennent des valeurs discrètes et non plus continues. The file will be sent to your Kindle account. One of them is the low-energy limit: does loop quantum gravity have general relativity as the correct low-energy limit. Not really an introduction. Do you believe that this item violates a copyright? It modifies our understanding of time, space and matter. Quantum gravity is among the most fascinating problems in physics. A simple argument indicates that covariant loop gravity (spinfoam theory) predicts a maximal acceleration, and hence forbids the development of curvature singularities. This book focuses on the physical and conceptual aspects of the problem and includes the background material needed to enter this lively domain of research, making it ideal for researchers and graduate students. In 1988, Rovelli, Lee Smolin and Abhay Ashtekar introduced a theory of quantum gravity called loop quantum gravity. Covariant Loop Quantum Gravity, the State of the Art The covariant (spinfoam) formulation of loop gravity is a tentative physical quantum theory of gravity with well defined transition amplitudes. It modifies our understanding of time, space and matter. Equations Faded and Small in Kindle Editon, Reviewed in the United States on March 8, 2017.
