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.

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.

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.

Engaging and accessible, this book teaches readers how to use inferential statistical thinking to check their assumptions, assess evidence about their beliefs, and avoid overinterpreting results that may look more promising than they really are. It provides step-by-step guidance for using both classical (frequentist) and Bayesian approaches to inference. Statistical techniques covered side by side from both frequentist and Bayesian approaches include hypothesis testing, replication, analysis of variance, calculation of effect sizes, regression, time series analysis, and more. Students also get a complete introduction to the open-source R programming language and its key packages. Throughout the text, simple commands in R demonstrate essential data analysis skills using real-data examples. The companion website provides annotated R code for the book's examples, in-class exercises, supplemental reading lists, and links to online videos, interactive materials, and other resources. ÿ Pedagogical Features *Playful, conversational style and gradual approach; suitable for students without strong math backgrounds. *End-of-chapter exercises based on real data supplied in the free R package. *Technical explanation and equation/output boxes. *Appendices on how to install R and work with the sample datasets.ÿ

Placebo cures. Global warming. Extraterrestrial life. Psychokinesis. In a time when scientific claims can sound as strange as science fiction--and can have a profound effect on individual life or public policy--assessing the merits of a far-out, supposedly scientific idea can be as difficult as it is urgent. Into the breach between helpless gullibility and unyielding skepticism steps physicist Robert Ehrlich, with an indispensable guide to making sense of "scientific" claims. A series of case studies of some of the most controversial (and for the judging public, deeply vexing) topics in the natural and social sciences, Ehrlich's book serves as a primer for evaluating the evidence for the sort of strange-sounding ideas that can shape our lives. A much-anticipated follow-up to his popular Nine Crazy Ideas in Science, this book takes up issues close to readers' everyday reality--issues such as global warming, the dangers of cholesterol, and the effectiveness of placebos--as well as questions that resonate through (and beyond) civic life: Is intelligent design a scientific alternative to evolution? Is homosexuality primarily innate? Are people getting smarter or dumber? In each case, Ehrlich shows readers how to use the tools of science to judge the accuracy of strange ideas and the trustworthiness of ubiquitous "experts." As entertaining as it is instructive, his book will make the work of living wisely a bit easier and more reliable for scientists and nonscientists alike.

The best backyard experiments for hands-on science learning The Ultimate Book of Saturday Science is Neil Downie's biggest and most astounding compendium yet of science experiments you can do in your own kitchen or backyard using common household items. It may be the only book that encourages hands-on science learning through the use of high-velocity, air-driven carrots. Downie, the undisputed maestro of Saturday science, here reveals important principles in physics, engineering, and chemistry through such marvels as the Helevator—a contraption that's half helicopter, half elevator—and the Rocket Railroad, which pumps propellant up from its own track. The Riddle of the Sands demonstrates why some granular materials form steep cones when poured while others collapse in an avalanche. The Sunbeam Exploder creates a combustible delivery system out of sunlight, while the Red Hot Memory experiment shows you how to store data as heat. Want to learn to tell time using a knife and some butter? There's a whole section devoted to exotic clocks and oscillators that teaches you how. The Ultimate Book of Saturday Science features more than seventy fun and astonishing experiments that range in difficulty from simple to more challenging. All of them are original, and all are guaranteed to work. Downie provides instructions for each one and explains the underlying science, and also presents experimental variations that readers will want to try.
