As anyone from cold climates knows, living with lots of ice and snow can lead to a special appreciation of sports such as skiing, sledding, and skating. Prolific physics popularizer Mark Denny’s take on winter athletics lays out the physical principles that govern glaciated game play.After discussing the physical properties of ice and snow and describing the physics behind sliding friction and aerodynamic drag, Denny applies these concepts to such sports as bobsledding, snowboardin...

Using a unique blend of physics and history, this book explores the dynamics of ancient weapons within a historical context. The factors that influenced the development and usefulness of ancient weapons are manifold, from the materials available at the time and the technology needed to assemble them, to conditions in which they were used and their capabilities relative to other available weaponry. This book takes the main categories of ancient weapons – bows, boomerangs, spears, slings, an...

The world's oceans account for roughly 71 percent of the planet's surface and 99 percent of its livable volume. Any study of this huge habitat requires a solid foundation in the principles that underlie marine biology and physical and chemical oceanography, yet until now undergraduate textbooks have largely presented compilations of facts rather than explanations of principles. How the Ocean Works fills this gap, providing a concise and accessible college-level introduction to mar...

Have you ever wondered how stealth planes achieve "invisibility," how sunken ships are found, or how fishermen track schools of fish in vast expanses of ocean? Radar and sonar echolocation—a simple matter of sending, receiving, and processing signals.Weaving history with simple science, Mark Denny deftly reveals the world of radar and sonar to the curious reader, technology buff, and expert alike. He begins with an early history of the Chain Home radar system used during World War ...

An "extraordinary guide to the hidden secrets of modern man-made miracles . . . Highly recommended" —from the author of Froth!: The Science of Beer ( Midwest Book Review).Ever wonder how a graceful and slender bridge can support enormous loads over truly astonishing spans? Why domes and free-standing arches survive earthquakes that flatten the rest of a city?Physicist Mark Denny looks at the large structures around us—tall buildings, long br...

A deep dive into pivotal technological advances in areas from warfare to time measurement. "A wonderful combination of history and physics." —Mark Kidger, author of Astronomical EnigmasIngenium is medieval English vernacular for "an ingenious contrivance." In this fascinating book, physicist Mark Denny considers five such contrivances—the bow and arrow, the waterwheel, the counterpoise siege engine (including the trebuchet), the pendulum clock anch...

Conversations with Marco Polo is a biography of Eugene Haderlie, whose extraordinary life is deeply intertwined with the 20th century: a rough-and-tumble childhood in Wyoming during the Depression; an undergraduate expedition to Baja Mexico, where he crossed paths with John Steinbeck and had his inflamed appendix taken out by a veterinarian; two years as hard-hat diver in World War II, defusing mines in the English Channel and enduring the trauma of D-Day. The conversations recorded here a...

The science of ballistics has a long history and starts with one question: How does a projectile move through the air? Even before physicists worked that one out, military engineers had been tinkering with ballistic devices for centuries. The trebuchet of the Middle Ages has given way to rocket power, and the science of ballistics has evolved to match the technology. Mark Denny’s survey covers this dynamic subject from prehistory to the weapons of tomorrow.Taking the bang-whiz-thud...

In Long Hops, physicist Mark Denny explains, in a clear, conversational style, the science of bird migration—from the intricacies of bird aeronautics to the newly unraveled mysteries of their magnetic compasses. While providing wherever possible examples of indigenous Hawaiian species, the book surveys the migration phenomenon as a whole, showing that birds are breathtaking works of engineering with spectacular capabilities for long-distance flights. Each year thousands of these h...

Watt’s up? A reader-friendly introduction to all things power.Power generation is a relatively recent concern because humans had little need for sustained power until the dawn of the Industrial Revolution. Today, modern civilization is wholly dependent on the production and distribution of power. Without it, our way of life would be extinguished.In Lights On!, Mark Denny reveals the mysterious world of power generation. He takes us on a fun tour, e...

Humans have changed the Earth so profoundly that we’ve ushered in the first new geologic period since the ice ages. So, what are we going to do about it?Ever since Nobel Prize–winning atmospheric chemist Paul Crutzen coined the term "Anthropocene" to describe our current era—one in which human impact on the environment has pushed Earth into an entirely new geological epoch—arguments for and against the new designation have been raging. Finally, an official working ...
