Using 100s of fascinating examples, James Burke shows how old established ideas in science and technology often lead to serendipitous and amazing modern discoveries and innovations.

    And from the ancients who plotted its path at Stonehenge to the modern scientists who unraveled the nuclear fusion reaction that turns mass into energy, humankind has sought to solve its mysteries. In this lively biography of the sun, Bob Berman ranges from its stellar birth to its spectacular future death with a focus on the wondrous and enthralling, and on the heartbreaking sacrifice, laughable errors, egotistical battles, and brilliant inspirations of the people who have tried to understand its power. What, exactly, are the ghostly streaks of light astronauts see-but can't photograph-when they're in space? And why is it impossible for two people to see the exact same rainbow? Why are scientists beginning to think that the sun is safer than sunscreen? And how does the fluctuation of sunspots-and its heartbeat-affect everything from satellite communications to wheat production across the globe? Peppered with mind-blowing facts and memorable anecdotes about spectral curiosities-the recently-discovered "second sun" that lurks beneath the solar surface, the eerie majesty of a total solar eclipse-The Sun's Heartbeat offers a robust and entertaining narrative of how the Sun has shaped humanity and our understanding of the universe around us.

    To his contemporaries he was a minor disciple of Emerson; he has since joined the ranks of America's most respected and beloved writers. Few, however, really know the complexity of the man they revere — wanderer and scholar, naturalist and humorist, teacher and surveyor, abolitionist and poet, Transcendentalist and anthropologist, inventor and social critic, and, above all, individualist.In this widely acclaimed biography, outstanding Thoreau scholar Walter Harding presents all of these Thoreaus. Scholars will find here the culmination of a lifetime of research and study, meticulously documented; general readers will find an absorbing story of a remarkable man. Writing always with supreme clarity, Professor Harding has marshaled all the facts so as best to "let them speak for themselves." Thoreau's thoughtfulness and stubbornness, his more than ordinarily human amalgam of the earthy and the sublime, his unquenchable vitality emerge to the reader as they did to his own family, friends, and critics.You will see Thoreau's work in his family's pencil factory, his accidental setting of a forest fire, his love of children and hatred of hypocrisy, his contributions to the scientific understanding of forest trees, and other more and less familiar aspects of the man and his works. You will find the social as well as the reclusive Thoreau. Reactions to him by such notable contemporaries as Margaret Fuller, Nathaniel Hawthorne, and Walt Whitman — with Thoreau's responses to them — are given in rich detail.The totality is as complete, accurate, fair, vivid, and fully rounded a portrait as has ever been drawn. On its appearance, Professor Harding's work immediately established itself as "the standard biography" (Edward Wagenknecht). It has never been superseded. For this Dover edition, the author has corrected minor errors, provided an appendix bibliographically documenting hundreds of facts, and contributed an Afterword updating some of his findings and discussing Thoreau scholarship.

    He skillfully portrays the daily lives of herdsmen and hunter-gatherers; the drama of the predator kills; the hundreds of exotic animals; the breathtaking landscapes; and the area's turbulent natural, political, and social histories.

    From Hindu mythology to Aztec sacrifices, butterflies have served as a metaphor for resurrection and transformation. Even during World War II, children in a Polish death camp scratched hundreds of butterflies onto the walls of their barracks. But as Russell points out in this rich and lyrical meditation, butterflies are above all objects of obsession. From the beastly horned caterpillar, whose blood helps it count time, to the peacock butterfly, with wings that hiss like a snake, Russell traces the butterflies through their life cycles, exploring the creatures' own obsessions with eating, mating, and migrating. In this way, she reveals the logic behind our endless fascination with butterflies as well as the driving passion of such legendary collectors as the tragic Eleanor Glanville, whose children declared her mad because of her compulsive butterfly collecting, and the brilliant Henry Walter Bates, whose collections from the Amazon in 1858 helped develop his theory of mimicry in nature. Russell also takes us inside some of the world's most prestigious natural history museums, where scientists painstakingly catalogue and categorize new species of Lepidoptera, hoping to shed light on insect genetics and evolution. A luminous journey through an exotic world of obsession and strange beauty, this is a book to be treasured by anyone who's ever watched a butterfly mid-flight and thought, as Russell has, "I've entered another dimension."

    But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity.There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

Life's Matrix also examines the grim realities of depletion of natural resources and its effects on the availability of water in the twenty-first century.
