Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    Though the history of alchemy is intricately linked to the history of chemistry, alchemy has nonetheless often been dismissed as the realm of myth and magic, or fraud and pseudoscience. And while its themes and ideas persist in some expected and unexpected places, from the Philosophers’ (or Sorcerer’s) Stone of Harry Potter to the self-help mantra of transformation, there has not been a serious, accessible, and up-to-date look at the complete history and influence of alchemy until now.In The Secrets of Alchemy, Lawrence M. Principe, one of the world’s leading authorities on the subject, brings alchemy out of the shadows and restores it to its important place in human history and culture. By surveying what alchemy was and how it began, developed, and overlapped with a range of ideas and pursuits, Principe illuminates the practice. He vividly depicts the place of alchemy during its heyday in early modern Europe, and then explores how alchemy has fit into wider views of the cosmos and humanity, touching on its enduring place in literature, fine art, theater, and religion as well as its recent acceptance as a serious subject of study for historians of science. In addition, he introduces the reader to some of the most fascinating alchemists, such as Zosimos and Basil Valentine, whose lives dot alchemy’s long reign from the third century and down to the present day. Through his exploration of alchemists and their times, Principe pieces together closely guarded clues from obscure and fragmented texts to reveal alchemy’s secrets, and—most exciting for budding alchemists—uses them to recreate many of the most famous recipes in his lab, including those for the “glass of antimony” and “philosophers’ tree.” This unique approach brings the reader closer to the actual work of alchemy than any other book.A concise but illuminating history, The Secrets of Alchemy is written for anyone drawn to the alchemical arts, those who are fascinated by the science as well as the fantastic stories and mysterious practitioners.

    While he was working on his Atomic Energy badge for the Boy Scouts, David’s obsessive attention turned to nuclear energy. Throwing caution to the wind, he plunged into a new project: building a model nuclear reactor in his backyard garden shed.Posing as a physics professor, David solicited information on reactor design from the U.S. government and from industry experts. Following blueprints he found in an outdated physics textbook, David cobbled together a crude device that threw off toxic levels of radiation. His wholly unsupervised project finally sparked an environmental emergency that put his town’s forty thousand suburbanites at risk. The EPA ended up burying his lab at a radioactive dumpsite in Utah. This offbeat account of ambition and, ultimately, hubris has the narrative energy of a first-rate thriller.

    Turing’s openness about his homosexuality at a time when it was an imprisonable offense ultimately led to his untimely lo death at the age of only forty-one. In Alan Turing: Unlocking the Enigma, David Boyle reveals the mysteries behind the man and his remarkable career. Aged just 22, Turing was elected a fellow at King's College, Cambridge on the strength of a dissertation in which he proved the central limit theorem. By the age of 33, he had been awarded the OBE by King George VI for his wartime services: Turing was instrumental in cracking the Nazi Enigma machines at the top secret code breaking establishment at Bletchley Park during the Second World War.But his achievements were to be tragically overshadowed by the paranoia of the post-War years. Hounded for his supposedly subversive views and for his sexuality, Turing was prosecuted in 1952, and forced to accept the humiliation of hormone treatment to avoid a prison sentence. Just two years later, at the age of 41 he was dead. The verdict: cyanide poisoning.Was Turing’s death accidental as his mother always claimed? Or did persistent persecution drive him to take him own life?Alan Turing: Unlocking the Enigma seeks to find the man behind the science, illuminating the life of a person who is still a shadowy presence behind his brilliant achievements.

    He studied the flight patterns of birds to create some of the first human flying machines; designed military weapons and defenses; studied optics, hydraulics, and the workings of the human circulatory system; and created designs for rebuilding Milan, employing principles still used by city planners today. Perhaps most importantly, Leonardo pioneered an empirical, systematic approach to the observation of nature-what is known today as the scientific method.Drawing on over 6,000 pages of Leonardo's surviving notebooks, acclaimed scientist and bestselling author Fritjof Capra reveals Leonardo's artistic approach to scientific knowledge and his organic and ecological worldview. In this fascinating portrait of a thinker centuries ahead of his time, Leonardo singularly emerges as the unacknowledged “father of modern science.”From the Trade Paperback edition.

    16 years later, the French Ambassador Hugues de Terlon secretly unearthed Descartes' bones & transported them to France. Why would this devoutly Catholic official care so much about the remains of a philosopher who was hounded from country to country on charges of atheism? Why would Descartes' bones take such a strange, serpentine path over the next 350 years—a path intersecting some of the grandest events imaginable: the birth of science, the rise of democracy, the mind-body problem, the conflict between faith & reason? Their story involves people from all walks of life—Louis XIV, a Swedish casino operator, poets & playwrights, philosophers & physicists, as these people used the bones in scientific studies, stole them, sold them, revered them as relics, fought over them, passed them surreptitiously from hand to hand. The answer lies in Descartes’ famous phrase: Cogito ergo sum—"I think, therefore I am." In his deceptively simple 78-page essay, Discourse on the Method, this small, vain, vindictive, peripatetic, ambitious Frenchman destroyed 2000 years of received wisdom & laid the foundations of the modern world. At the root of Descartes’ method was skepticism: "What can I know for certain?" Like-minded thinkers around Europe passionately embraced the book--the method was applied to medicine, nature, politics & society. The notion that one could find truth in facts that could be proved, & not in reliance on tradition & the Church's teachings, would become a turning point in human history. In an age of faith, what Descartes was proposing seemed like heresy. Yet Descartes himself was a good Catholic, who was spurred to write his incendiary book for the most personal of reasons: He'd devoted himself to medicine & the study of nature, but when his beloved daughter died aged 5, he took his ideas deeper. To understand the natural world one needed to question everything. Thus the scientific method was created & religion overthrown. If the natural world could be understood, knowledge could be advanced, & others might not suffer as his child did. The great controversy Descartes ignited continues to our era: where Islamic terrorists spurn the modern world & pine for a culture based on unquestioning faith; where scientists write bestsellers that passionately make the case for atheism; where others struggle to find a balance between faith & reason. Descartes’ Bonesis a historical detective story about the creation of the modern mind, with twists & turns leading up to the present day—to the science museum in Paris where the philosopher’s skull now resides & to the church a few kilometers away where, not long ago, a philosopher-priest said a mass for his bones.

    But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's Copenhagen interpretation and dismissed questions about the reality underlying quantum physics as meaningless. A mishmash of solipsism and poor reasoning, Copenhagen endured, as Bohr's students vigorously protected his legacy, and the physics community favored practical experiments over philosophical arguments. As a result, questioning the status quo long meant professional ruin. And yet, from the 1920s to today, physicists like John Bell, David Bohm, and Hugh Everett persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and of the courageous scientists who dared to stand up for truth.

    In Everything All At Once, the New York Times bestselling author issues a call to arms meant to rouse everyone to become the change they want to see in the world. Whether addressing global warming, social change, or personal success, there are certain strategies that always get results: looking at the world with radical curiosity, being driven by a desire for a better future, and being willing to take the actions needed to make change a reality.With his signature humor and storytelling, Bill shares how he has developed specific techniques for what he calls the "everything all at once" lifestyle, from his childhood scouting adventures and his career at aerospace companies to the development of his famous Science Guy television show. This approach requires the nerd mindset: a way of thinking that leaves no stone unturned. It's about learning to solve problems through exploration, trial and error, and sheer creativity. Problem solving is a skill that anyone can harness to create change, and Bill Nye is here to show us how to sort out problems, recognize solutions, and join him in changing the world.

    The instantly recognizable Sagan, a fixture on television and a bestselling author, offered the layperson entry into the mysteries of the cosmos and of science in general. To much of the scientific community, however, he was a pariah, a brazen publicity seeker who cared more about his image and his fortune than the advancement of science. Poundstone reveals the seldom-discussed aspects of Sagan's life, the legitimate and important work of his early scientific career, the almost obsessive capacity to take on endless projects, and the multiple marriages and fractured personal life, in what The New Yorker called an "evenhanded guide" to a great man's career.

    You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists see things differently, from Newton to Einstein to today’s quantum theorists. For them, time isn’t real. You may think you experience time passing, but they say it’s just an illusion.Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues this limited notion of time is holding physics back. It’s time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics.What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilties. There are few ideas that, like our notion of time, shape our thinking about literally everything, with major implications for physics and beyond—from climate change to the economic crisis. Smolin explains in lively and lucid prose how the true nature of time impacts our world.

    Some were people of rank and influence. Some were ordinary folk. Some were even his friends. Four centuries later, these deeply moving accounts of faith and courage mark a path for modern Christians to measure the depth of their commitment.

    Petr Beckmann holds up this mirror, giving the background of the times when pi made progress -- and also when it did not, because science was being stifled by militarism or religious fanaticism.

    Traitor to His Class sheds new light on FDR's formative years, his remarkable willingness to champion the concerns of the poor and disenfranchised, his combination of political genius, firm leadership, and matchless diplomacy in saving democracy in America during the Great Depression and the American cause of freedom in World War II. Drawing on archival materials, public speeches, personal correspondence, and accounts by family and close associates, acclaimed bestselling historian and biographer H. W. Brands offers a compelling and intimate portrait of Roosevelt’s life and career.Brands explores the powerful influence of FDR’s dominating mother and the often tense and always unusual partnership between FDR and his wife, Eleanor, and her indispensable contributions to his presidency. Most of all, the book traces in breathtaking detail FDR’s revolutionary efforts with his New Deal legislation to transform the American political economy in order to save it, his forceful—and cagey—leadership before and during World War II, and his lasting legacy in creating the foundations of the postwar international order. Traitor to His Class brilliantly captures the qualities that have made FDR a beloved figure to millions of Americans.

    We see him at work in times of declining liberalism, devastating war, uneasy peace, the rise of Hitler and the fall of Austria. We watch him devising and revising his epoch-making theories. We are there as he struggles toward his discoveries, haunted by the problems he poses for himself, brooding over his publications, quarreling with his disciples. And we encounter Freud, always energetic, often troubled and sometimes vindictive, as his ideas spread from a small inner circle in Vienna, through Europe, across the ocean to the United States⁠—and the world.Drawing on a vast instructive store of unpublished documents, including hundreds of hitherto unknown or inaccessible letters, Peter Gay probes Freud's mind, uncovers Freud's passions, and follows Freud's astonishing career. He analyzes Freud the psychoanalyst as politician, seeking support for his controversial findings. He discloses for the first time the dimensions of Freud's love for his daughter Anna, and his unorthodox analysis of her. He offers a thoughtful, detailed, fascinating account of Freud's relations with such problematic followers as Jung and Ferenczi. He deals frankly with the controversies that have long swirled around Freud's impassioned friendships, his love life, and his theoretical innovations, which, as Freud himself put it, agitated the sleep of mankind.Perhaps most important and rewarding of all. no previous biography has so securely integrated into Freud's life his case histories, technical papers, speculative aesthetics, and excursions into prehistory and cultural criticism. The sections scattered across this book in which Peter Gay lucidly expounds and explains Freud's theories of dreams and sexuality, development and neurosis, love and hate amount to a comprehensive⁠—and comprehensible⁠—liberal education in psychoanalytic thought, which is far more discussed than it is understood. Fitting as they do into Freud's most intimate concerns and cultural loyalties, these ideas gain a vivid life of their own.The reader will long remember the Freud that Peter Gay reveals here⁠—student, physician, psychologist, lover, husband, father, friend, founder, controversialist, Jew, victim, and victor. This book, brilliantly argued and brilliantly written, evokes an age, and the life and ideas of a man who, in W. H. Auden's phrase, is "no more a person now but a whole climate of opinion.

    As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species.
