Why Toast Lands Jelly-Side Down by Robert Ehrlich Pdf

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 long-awaited 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 Jelly-Side 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 Jelly-Side 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 hard-to-find 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 set-up 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 Jelly-Side 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.

Merry Wives and Others by Penelope Fritzer,Bartholomew Bland Pdf

In many ways, the history of domestic humor writing is also a history of domestic life in the twentieth century. For many years, domestic humor was written primarily by females; significant contributions from male writers began as times and family structures changed. It remains timeless because of its basis on the relationships between husbands and wives, parents and children, houses and inhabitants, pets and their owners, chores and their doers, and neighbors. This work is a historical and literary survey of humorists who wrote about home. It begins with a chapter on the social context of and attitudes toward traditional domestic roles and housewives. The following chapters, beginning with the 1920s and continuing through today, cover the different time periods and the foremost American domestic humorists, and the humor written by surrogate parents, grown children about their childhood families, husbands, and Canadian and English writers. Also covered are the differences among various writers toward traditional domestic roles--some, like Erma Bombeck and Judith Viorst, embraced them, while others, like Caryl Kristenson and Marilyn Kentz, resisted them. Common themes, such as the isolation and competitiveness of housework, home as an idealized metaphysical goal and ongoing physical challenge, and the urban, suburban, and rural life, are also explored.

Vacuum Bazookas, Electric Rainbow Jelly, and 27 Other Saturday Science Projects by Neil A. Downie Pdf

How do you crack nuts with a piece of string? Reverse gravity? Cobble together a clock out of a coffee cup, a soda bottle, and some water? Use a vacuum cleaner and nineteenth-century railroad technology to fashion a makeshift bazooka that can launch paper projectiles? Create a rainbow in a block of Jello? This is a one-volume romp through a whole array of counterintuitive science experiments that require little more than common household items and a sense of curiosity. Prepare to have your surprise sensors on overload as Neil Downie stretches math, physics, and chemistry to do what they have never done before. This book describes twenty-nine unusual but practical experiments, detailing how they are done and the math and physics behind them. It will delight both casual and inveterate tinkerers. Of varying levels of complexity, the experiments are grouped in sections covering a wide field of physics and the borders of chemistry, ranging from dynamic mechanics (''Kinetic Curiosities'') to electricity (''Antediluvian Electronics'') and combustion (''Infernal Inventions''). The chapters are titillatingly titled, from ''Twisted Sinews'' and ''Mole Radio'' to ''A Symphony of Siphons'' and ''Tornado Transistor.'' More-detailed explanations, along with simple mathematical models using high-school level math, are given in boxes accompanying each experiment. Armchair scientists will welcome this edifying and entertaining alternative to idleness, not least for the buoyant prose, enriched by historical and literary anecdotes introducing each topic. With this book in hand, tinkerers, whether dabblers in science or devotees, students or teachers, need never again wonder how to impress friends, the judges at the science fair, and, not least, themselves.

Seeing through Zen by John R. Mcrae Pdf

The tradition of Chan Buddhism—more popularly known as Zen—has been romanticized throughout its history. In this book, John R. McRae shows how modern critical techniques, supported by recent manuscript discoveries, make possible a more skeptical, accurate, and—ultimately—productive assessment of Chan lineages, teaching, fundraising practices, and social organization. Synthesizing twenty years of scholarship, Seeing through Zen offers new, accessible analytic models for the interpretation of Chan spiritual practices and religious history. Writing in a lucid and engaging style, McRae traces the emergence of this Chinese spiritual tradition and its early figureheads, Bodhidharma and the "sixth patriarch" Huineng, through the development of Zen dialogue and koans. In addition to constructing a central narrative for the doctrinal and social evolution of the school, Seeing through Zen examines the religious dynamics behind Chan’s use of iconoclastic stories and myths of patriarchal succession. McRae argues that Chinese Chan is fundamentally genealogical, both in its self-understanding as a school of Buddhism and in the very design of its practices of spiritual cultivation. Furthermore, by forgoing the standard idealization of Zen spontaneity, we can gain new insight into the religious vitality of the school as it came to dominate the Chinese religious scene, providing a model for all of East Asia—and the modern world. Ultimately, this book aims to change how we think about Chinese Chan by providing new ways of looking at the tradition.

What If You Could Unscramble an Egg? by Robert Ehrlich Pdf

A whimsical construction of an imaginary dialogue between two people intent on understanding esoteric topics that range from human sexuality to physics. Ehrlich (physics, George Mason U.) is dedicated to making the sciences fun and interesting, and though the conceit is "cute," the information it contains is dynamic and scientifically sound, posing interesting questions and speculations on life in the universe, human behavior, perception, gravity, material properties, physics, time, space, and a sample list of "What ifs?" to pursue on one's own. The answer to the title's question (we were dying to know) is that, in part, it's all a matter of probabilities. The promotional material says the cartoons are humorous. Not.
