{"product_id":"9781101117705","title":"Relativity: The Special and the General Theory","description":"Robert Geroch builds on Einstein's work with commentary that addresses the ideas at the heart of the theory, bringing a modern understanding of relativity to the text. He elucidates how special relativity is a reconciliation of the contradictions between the nature of light and the principle of relativity; he expands on Einstein's treatment of the geometry of space-time and the fundamental notion of an \"event\"; he explains in detail, but without technical language, the equivalence of inertial and gravitational mass, a cornerstone of general relativity.","brand":"Penguin Publishing Group","offers":[{"title":"Default Title","offer_id":47120806641904,"sku":"9781101117705","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781101117705_p0.jpg?v=1763685030","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781101117705","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
