Why Toast Lands JellySide Down: Zen and the Art of Physics Demonstrations,Used
Delivery time: 8-12 business days (International)
Physics has the reputation of being difficult to understand and remote from everyday life. Robert Ehrlich, however, has spent much of his career disproving these stereotypes. In the longawaited sequel to Turning the World Inside Out and 175 Other Simple Physics Demonstrations, he provides a new collection of physics demonstrations and experiments that prove that physics can, in fact, be 'made simple.' Intentionally using 'low tech' and inexpensive materials from everyday life, Why Toast Lands JellySide Down makes key principles of physics surprisingly easy to understand.After laying out the basic principles of what constitutes a successful demonstration, Ehrlich provides more than 100 examples. Some of the more intriguing include: Terminal Velocity of Falling Coffee Filters; Spinning a Penny; Dropping Two Rolls of Toilet Paper; Avalanches in a Sand Pile; When to Add the Cream to Your Coffee; Deep Knee Bends on a Bathroom Scale; Recoil Force on a Bent Straw; Swinging Your Arms While Walking; Estimating the Net Force on a Moving Book; and, of course, Why Toast Lands JellySide Down.The book begins with a practical introduction on how to design physics demonstrations. The benefits of designing one's own 'demos' are numerous, but primary among them is an increased understanding of basic physics. For many people who teach the principles of physics, demonstrations seem dauntingly complex, filled with hardtofind equipment and too many possibilities for failure. The demonstrations described in this book are exactly the opposite. Ehrlich describes them with characteristic candor: 'You can fit many of them in your pocket, bring them to your class without any setup required, and best of all, you need not fear that your demo will more likely illustrate Murphy's laws rather than Newton's.'For anyone with even the slightest interest in physics, Why Toast Lands JellySide Down is filled with learning opportunities. For everyone who is studying physics or teaching the subject at any level, from amateur scientists to professional teachers, it is an essential resource.
