The book describes how the theory naturally blends gravity into the other forces, providing a hope for an integrated theory of the forces of nature.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eDimension\u003c\/strong\u003e: 235 x 155 (mm)\u003cbr\u003e\u003cstrong\u003eISBN-13\u003c\/strong\u003e: 9789819507313\u003c\/p\u003e","brand":"Daniel Greenberger","offers":[{"title":"Hardback","offer_id":50037258649850,"sku":"9789819507313","price":59.46,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/files\/1786150751308_book.jpg?v=1786197050","url":"https:\/\/shulphink.com\/products\/proper-time-and-mass-as-dynamical-variables-why-its-possible-and-some-consequences-9789819507313","provider":"Shulph Ink","version":"1.0","type":"link"}
