Description
Book SynopsisCovering 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.
Trade ReviewThis 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 2004 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 2004 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 2004
