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 group of ......
As anyone from cold climates knows, frequently occurring ice and snow 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 how ......
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 ......

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 ......

The Science of Bridges, Buildings, Dams, and Other Feats of Engineering
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 bridges, and big dams -- and explains how they were designed and built and ......
