Self-organized criticality, the spontaneous development of systems to a critical state, is the first general theory of complex systems with a firm mathematical basis. This theory describes how many seemingly desperate aspects of the world, from stock market crashes to mass extinctions, avalanches to solar flares, all share a set of simple, easily described properties. "...a'must read'...Bak writes with such ease and lucidity, and his ideas are so intriguing...essential reading for those interested in complex systems...it will reward a sufficiently skeptical reader." -NATURE "...presents the theory (self-organized criticality) in a form easily absorbed by the non-mathematically inclined reader." -BOSTON BOOK REVIEW "I picture Bak as a kind of scientific musketeer; flamboyant, touchy, full of swagger and ready to join every fray... His book is written with panache. The style is brisk, the content stimulating. I recommend it as a bracing experience." -NEW SCIENTIST

We now live on a planet that is troubled—even overworked—in ways that compel us to reckon with inherited common sense about the relationship between human labor and nonhuman nature. In Paraguay, fast-growing soy plants are displacing both prior crops and people. In Malaysia, dispossessed farmers are training captive orangutans to earn their own meals. In India, a prized dairy cow suddenly refuses to give more milk. Built from these sorts of scenes and sites, where the ultimate subjects and agents of work are ambiguous, How Nature Works develops an anthropology of labor that is sharply attuned to the irreversible effects of climate change, extinction, and deforestation. The authors of this volume push ethnographic inquiry beyond the anthropocentric documentation of human work on nature in order to develop a language for thinking about how all labor is a collective ecological act.

In this inspiring manifesto, an internationally renowned ecologist makes a clear case for why protecting nature is our best health insurance, and why it makes economic sense.

The second in the Reader's Digest Science series, How Nature Works is designed to open up the world of natural history to children and adults with a practical, hands-on approach to nature that involves the reader in doing experiments in order to learn. All the experiments and demostrations have been carefully planned and photographed "live" using over 700 full-color photographs. Publication date: September 1st.

*Junior Library Guild Selection 2017* Only a few dozen vertebrate animals have evolved true gliding abilities, but they include an astonishing variety of mammals, reptiles, and amphibians. North America’s flying squirrels and Australia’s sugar gliders notwithstanding, the vast majority of them live in rainforests. Illustrated with arresting photographs, Catching Air takes us around the world to meet these animals, learn why so many gliders live in Southeast Asia, and find out why this gravity-defying ability has evolved in Draco lizards, snakes, and frogs as well as mammals. Why do gliders stop short of flying, how did bats make that final leap, and how did Homo sapiens bypass evolution to glide via wingsuits and hang gliders—or is that evolution in another guise?

Engineered by evolution to thrive in the wild How Birds Work goes beyond the typical field guide to show us not only what birds look like but why. Why do many owls have asymmetrical ear openings? (Hint: It helps them pinpoint prey; see page 40.) And why does the Grey Heron rest on one leg at a time? (Hint: Not because it’s tired; see page 66!) Birds boast a spectacular array of adaptations suited to their incredibly diverse diets and habitats. In this in-depth handbook, discover the ways they’re even more astounding than you know—inside and out. Detailed analysis and illustrations illuminate: Skeleton Muscles Circulation Digestion Respiration Reproduction Feathers Colors and Patterns And much, much more!
