Previously, he was awarded their Oersted Medal.\u003c\/p\u003e\u003cp\u003ePhysicists use \"back-of-the-envelope\" estimates to check whether or not an idea could possibly be right. In many cases, the approximate solution is all that is needed. This compilation of 101 examples of back-of-the-envelope calculations celebrates a quantitative approach to solving physics problems. Drawing on a lifetime of physics research and nearly three decades as the editor of \u003ci\u003eThe Physics Teacher\u003c\/i\u003e, Clifford Swartz provides simple, approximate solutions to physics problems that span a broad range of topics. What note do you get when you blow across the top of a Coke bottle? Could you lose weight on a diet of ice cubes? How can a fakir lie on a bed of nails without getting hurt? Does draining water in the northern hemisphere really swirl in a different direction than its counterpart below the equator? \u003c\/p\u003e\u003cp\u003eIn each case, only a few lines of arithmetic and a few natural constants solve a problem to within a few percent. Covering such subjects as astronomy, magnetism, optics, sound, heat, mechanics, waves, and electricity, the book provides a rich source of material for teachers and anyone interested in the physics of everyday life.\u003c\/p\u003e","brand":"Johns Hopkins University Press","offers":[{"title":"Paperback","offer_id":47781046157463,"sku":"9780801872631","price":3235.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9780801872631.webp?v=1778050149","url":"https:\/\/atlanticbooks.com\/products\/back-of-the-envelope-physics-9780801872631","provider":"Atlantic Books","version":"1.0","type":"link"}
