{"product_id":"the-grand-design-3","title":"The grand design","description":"Along with Caltech physicist Mlodinow (The Drunkard's Walk), University of Cambridge cosmologist Hawking (A Brief History of Time) deftly mixes cutting-edge physics to answer three key questions-- Why is there something rather than nothing? Why do we exist? Why this particular set of laws and not some other?-- and explains that scientists are approaching what is called \"M-theory,\" a collection of overlapping theories (including string theory) that fill in many (but not all) the blank spots in quantum physics. This collection is known as the \"Grand Unified Field Theories.\"","brand":"Blue Vase Bulk","offers":[{"title":"Used \/ 9780553384666-001","offer_id":43872307380285,"sku":"9780553384666-001","price":4.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0589\/4225\/9261\/files\/37513482385.jpg?v=1792679257","url":"https:\/\/www.bluevasebooks.com\/products\/the-grand-design-3","provider":"Blue Vase Books","version":"1.0","type":"link"}
