{"product_id":"feynman-lectures-on-gravitation-book-richard-feynman-9780813340388","title":"Feynman Lectures On Gravitation","description":"The Feynman Lectures on Gravitation are based on notes prepared during a course on gravitational physics that Richard Feynman taught at Caltech during the 1962-63 academic year. For several years prior to these lectures, Feynman thought long and hard about the fundamental problems in gravitational physics, yet he published very little. These lectures represent a useful record of his viewpoints and some of his insights into gravity and its application to cosmology, superstars, wormholes, and gravitational waves at that particular time. The lectures also contain a number of fascinating digressions and asides on the foundations of physics and other issues.Characteristically, Feynman took an untraditional non-geometric approach to gravitation and general relativity based on the underlying quantum aspects of gravity. Hence, these lectures contain a unique pedagogical account of the development of Einstein's general theory of relativity as the inevitable result of the demand for a self-consistent theory of a massless spin-2 field (the graviton) coupled to the energy-momentum tensor of matter. This approach also demonstrates the intimate and fundamental connection between gauge invariance and the principle of equivalence.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49919034818833,"sku":"NGR9780813340388","price":84.89,"currency_code":"USD","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":51008032571665,"sku":"NIN9780813340388","price":79.99,"currency_code":"USD","in_stock":true},{"title":"US \/ GOOD \/ SBYB","offer_id":51333128192273,"sku":"CIN0813340381G","price":35.23,"currency_code":"USD","in_stock":false},{"title":"GB \/ NEW \/ INGRAM","offer_id":52333163839761,"sku":"NLS9780813340388","price":100.39,"currency_code":"USD","in_stock":true},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":52990121705745,"sku":"GOR005399744","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0813340381.jpg?v=1750850072","url":"https:\/\/www.worldofbooks.com\/products\/feynman-lectures-on-gravitation-book-richard-feynman-9780813340388","provider":"World of Books ","version":"1.0","type":"link"}
