{"product_id":"feynman-lectures-on-gravitation-like-new","title":"Feynman Lectures on Gravitation-Like new","description":"\u003cp\u003eThe 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 and 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 Einsteins general 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.\u003c\/p\u003e","brand":"Addison-Wesley","offers":[{"title":"Default Title","offer_id":47471818539253,"sku":"Prep-GR-0201627345","price":94.65,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/5804\/8501\/files\/91ekmz9TL1L_66b129ae-f9bd-47bc-8f1d-b6630f503f49.jpg?v=1767769794","url":"https:\/\/ergodebooks.com\/products\/feynman-lectures-on-gravitation-like-new","provider":"Ergodebooks","version":"1.0","type":"link"}
