If the physical world is to make sense to students (or even to professional scientists), then it must be understandable on the basis of broadly applicable principles and simple communicable reasoning. Long, dry calculations alone will not do, for they are as devoid of insight as they are impenetrable. Here, however, is a book of wide-ranging and aptly chosen topics-each brief glimpse conveying its (sometimes surprising!) lesson in one page with a short, physically insightful, quantitative argument. This is a book that will help make the study of physics fun and relevant. -- Mark P. Silverman, author of A Universe of Atoms... An Atom in the Universe and Waves and Grains: Reflections on Light and Learning This book is a treasure trove of fascinating calculations covering a wide range of physical principles, distance scales, and numerical orders of magnitude. Everyone with some curiosity about the natural world, from novice students to seasoned veterans, will find a variety of interesting cases in this wonderful collection. -- Gregory N. Derry, author of What Science Is and How It Works The book is fun to read. I look forward to mining it for examples with which to spice up my lectures. -- Don S. Lemons, author of Introduction to Stochastic Processes in Physics
Clifford Swartz is a professor emeritus of physics at State University of New York, Stony Brook. He was the editor of The Physics Teacher for twenty-nine years and has written numerous physics texts for students from kindergarten to graduate level. He was the recipient in 2007 of the Melba Newell Phillips Award and in 1987 of the Oersted Medal, the most prestigious award of the American Association of Physics Teachers.
This delightfully broad spectrum of 104 familiar situations, each one or two pages long, includes the terminal velocity of falling objects, fatal impacts during car wrecks, timing to find the distance of lightning strikes, investigating the size and power of binoculars, and the height of Earth's atmosphere... For the well-grounded physics enthusiast. Choice A physics educator's coffee-table book-a delightful and instructive accessory to an introductory physics course. Physics World Physicists young and old should follow Fermi and Swartz and hone a competency for back-of-the-envelope physics. -- Robert K. Adair Physics Today An entertaining new book Back-of-the-Envelope Physics by Clifford Swartz nicely provides material to assist students (and teachers!) gain experience in handling real-world physics. -- Colin Keay The Physicist
