From number one New York Times bestselling author Michael Pollan, a radical challenge to how we think about drugs, and an exploration into the powerful human attraction to psychoactive plants--and the equally powerful taboos Of all the things humans rely on plants for--sustenance, beauty, medicine, fragrance, flavor, fiber--surely the most curious is our use of them to change consciousness: to stimulate or calm, fiddle with or completely alter, the qualities of our mental experience. Take coffee and tea: People around the world rely on caffeine to sharpen their minds. But we do not usually think of caffeine as a drug, or our daily use as an addiction, because it is legal and socially acceptable. So, then, what is a "drug"? And why, for example, is making tea from the leaves of a tea plant acceptable, but making tea from a seed head of an opium poppy a federal crime? In This Is Your Mind on Plants , Michael Pollan dives deep into three plant drugs--opium, caffeine, and mescaline--and throws the fundamental strangeness, and arbitrariness, of our thinking about them into sharp relief. Exploring and participating in the cultures that have grown up around these drugs while consuming (or, in the case of caffeine, trying not to consume) them, Pollan reckons with the powerful human attraction to psychoactive plants. Why do we go to such great lengths to seek these shifts in consciousness, and then why do we fence that universal desire with laws and customs and fraught feelings? In this unique blend of history, science, and memoir, as well as participatory journalism, Pollan examines and experiences these plants from several very different angles and contexts, and shines a fresh light on a subject that is all too often treated reductively--as a drug, whether licit or illicit. But that is one of the least interesting things you can say about these plants, Pollan shows, for when we take them into our bodies and let them change our minds, we are engaging with nature in one of the most profound ways we can. Based in part on an essay published almost twenty-five years ago, this groundbreaking and singular consideration of psychoactive plants, and our attraction to them through time, holds up a mirror to our fundamental human needs and aspirations, the operations of our minds, and our entanglement with the natural world.

NEW YORK TIMES BESTSELLER Now in paperback--Peggy Orenstein, author of the groundbreaking New York Times bestseller Girls & Sex, turns her focus to the sexual lives of young men. "Eye-opening.... Every few pages, the boy world cracks open a little bit.... Even in the most anxiety-provoking moments of Boys & Sex, it's clear that Orenstein believes in the goodness of boys and the men they can become, and she believes in us, as parents, to raise them" (New York Times Book Review). Peggy Orenstein's Girls & Sex broke ground, shattered taboos, and launched conversations about young women's right to pleasure and agency in sexual encounters. It also had an unexpected effect on its author: Orenstein realized that talking about girls is only half the conversation. Boys are subject to the same cultural forces as girls--steeped in the same distorted media images and binary stereotypes of female sexiness and toxic masculinity--which equally affect how they navigate sexual and emotional relationships. In Boys & Sex, Peggy Orenstein dives back into the lives of young people to once again give voice to the unspoken, revealing how young men understand and negotiate the new rules of physical and emotional intimacy. Drawing on comprehensive interviews with young men, psychologists, academics, and experts in the field, Boys & Sex dissects so-called locker room talk; how the word "hilarious" robs boys of empathy; pornography as the new sex education; boys' understanding of hookup culture and consent; and their experience as both victims and perpetrators of sexual violence. By surfacing young men's experience in all its complexity, Orenstein is able to unravel the hidden truths, hard lessons, and important realities of young male sexuality in today's world. The result is a provocative and paradigm-shifting work that offers a much-needed vision of how boys can truly move forward as better men.

How can we make intelligent decisions about our increasingly technology-driven lives if we don't understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions. Casting a wide net through history and culture, Sagan examines and authoritatively debunks such celebrated fallacies of the past as witchcraft, faith healing, demons, and UFOs. And yet, disturbingly, in today's so-called information age, pseudoscience is burgeoning with stories of alien abduction, channeling past lives, and communal hallucinations commanding growing attention and respect. As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.--Amazon.com.

"The world's leading alien hunter" -- New York Times Magazine From acclaimed Harvard astrophysicist and bestselling author of Extraterrestrial comes a mind-expanding new book explaining why becoming an interstellar species is imperative for humanity's survival and detailing a game plan for how we can settle among the stars. In the New York Times bestseller Extraterrestrial, Avi Loeb, the longest serving Chair of Harvard's Astronomy Department, presented a theory that shook the scientific community: our solar system, Loeb claimed, had likely been visited by a piece of advanced alien technology from a distant star. This provocative and persuasive argument opened millions of minds internationally to the vast possibilities of our universe and the existence of intelligent life beyond Earth. But a crucial question remained: now that we are aware of the existence of extraterrestrial life, what do we do next? How do we prepare ourselves for interaction with interstellar extraterrestrial civilization? How can our species become interstellar? Now Loeb tackles these questions in a revelatory, powerful call to arms that reimagines the idea of contact with extraterrestrial civilizations. Dismantling our science-fiction fueled visions of a human and alien life encounter, Interstellar provides a realistic and practical blueprint for how such an interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. From awe-inspiring searches for extraterrestrial technology, to the heated debate of the existence of Unidentified Aerial Phenomena, Loeb provides a thrilling, front-row view of the monumental progress in science and technology currently preparing us for contact. He also lays out the profound implications of becoming--or not becoming--interstellar; in an urgent, eloquent appeal for more proactive engagement with the world beyond ours, he powerfully contends why we must seek out other life forms, and in the process, choose who and what we are within the universe. Combining cutting edge science, physics, and philosophy, Interstellar revolutionizes the approach to our search for extraterrestrial life and our preparation for its discovery. In this eye-opening, necessary look at our future, Avi Loeb artfully and expertly raises some of the most important questions facing us as humans, and proves, once again, that scientific curiosity is the key to our survival.

Perfect for middle grade readers and history enthusiasts, New York Times bestselling author Steve Sheinkin presents the fascinating and frightening true story of the creation behind the most destructive force that birthed the arms race and the Cold War in Bomb: The Race to Build — and Steal--the World's Most Dangerous Weapon . A Newbery Honor book A National Book Awards finalist for Young People's Literature A Washington Post Best Kids Books of the Year title In December of 1938, a chemist in a German laboratory made a shocking discovery: When placed next to radioactive material, a Uranium atom split in two. That simple discovery launched a scientific race that spanned three continents. In Great Britain and the United States, Soviet spies worked their way into the scientific community; in Norway, a commando force slipped behind enemy lines to attack German heavy-water manufacturing; and deep in the desert, one brilliant group of scientists was hidden away at a remote site at Los Alamos. This is the story of the plotting, the risk-taking, the deceit, and genius that created the world's most formidable weapon. This is the story of the atomic bomb. “This superb and exciting work of nonfiction would be a fine tonic for any jaded adolescent who thinks history is 'boring.' It's also an excellent primer for adult readers who may have forgotten, or never learned, the remarkable story of how nuclear weaponry was first imagined, invented and deployed—and of how an international arms race began well before there was such a thing as an atomic bomb.” — The Wall Street Journal “This is edge-of-the seat material that will resonate with YAs who clamor for true spy stories, and it will undoubtedly engross a cross-market audience of adults who dozed through the World War II unit in high school.” — The Bulletin (starred review) Also by Steve Sheinkin: The Notorious Benedict Arnold: A True Story of Adventure, Heroism & Treachery The Port Chicago 50: Disaster, Mutiny, and the Fight for Civil Rights Undefeated: Jim Thorpe and the Carlisle Indian School Football Team Most Dangerous: Daniel Ellsberg and the Secret History of the Vietnam War Which Way to the Wild West?: Everything Your Schoolbooks Didn't Tell You About Westward Expansion King George: What Was His Problem?: Everything Your Schoolbooks Didn't Tell You About the American Revolution Two Miserable Presidents: Everything Your Schoolbooks Didn't Tell You About the Civil War Born to Fly: The First Women's Air Race Across America

#1 New York Times and internationally bestselling author Naomi Klein makes the case for a Green New Deal in this “keenly argued, well-researched, and impassioned” manifesto ( The Washington Post ). An instant bestseller, On Fire shows Klein at her most prophetic and philosophical, investigating the climate crisis not only as a profound political challenge but also as a spiritual and imaginative one. Delving into topics ranging from the clash between ecological time and our culture of “perpetual now,” to the soaring history of humans changing and evolving rapidly in the face of grave threats, to rising white supremacy and fortressed borders as a form of “climate barbarism,” this is a rousing call to action for a planet on the brink. An expansive, far-ranging exploration that sees the battle for a greener world as indistinguishable from the fight for our lives, On Fire captures the burning urgency of the climate crisis, as well as the fiery energy of a rising political movement demanding a catalytic Green New Deal. “Naomi Klein’s work has always moved and guided me. She is the great chronicler of our age of climate emergency, an inspirer of generations.” —Greta Thunberg, climate activist "If I were a rich man, I’d buy 245 million copies of Naomi Klein’s 'On Fire' and hand-deliver them to every eligible voter in America…Klein is a skilled writer." —Jeff Goodell, The New York Times

The exclusive, first-hand, behind-the-scenes story of how Pfizer raced to create the first Covid-19 vaccine, told by Pfizer's CEO Dr. Albert Bourla A riveting, fast-paced, inside look at one of the most incredible private sector achievements in history, Moonshot recounts the intensive nine months in 2020 when the scientists at Pfizer, under the visionary leadership of Dr. Albert Bourla, made "the impossible possible"--creating, testing, and manufacturing a safe and effective Covid-19 vaccine that previously would have taken years to develop. Dr. Bourla chronicles how the brilliant, dedicated minds at Pfizer, under the enormous strains of the global pandemic, overcame a series of crises that were compounded by social and political unrest, and reveals the doubts, decisions, obstacles, and failures they encountered. As Dr. Bourla makes clear, Pfizer's success wasn't due to luck; it was because of preparation driven by four simple values--Courage, Excellence, Equity, and Joy. Moonshot is a story of leadership under the most unprecedented circumstances--how Dr. Bourla, a Greek immigrant, a child of Holocaust survivors, and a veterinarian, became the head of one of the world's largest corporations and initiated a dramatic transformation of the organization just before a global health crisis would serve to test the organization, its scientists and its leader, like never before. Moonshot describes best practices that can be used to address the multiple, unprecedented challenges our world faces, reveals Pfizer's implementation of scientific breakthroughs at a record-breaking pace, and offers leadership lessons that can help anyone successfully manage their own seemingly unsolvable problems. As Dr. Bourla explains, "I am sharing the story of our moonshot--the challenges we faced, the lessons we learned, and the core values that allowed us to make it happen--in hopes that it might inspire and inform your own moonshot, whatever that may be."

Soul Made Flesh is the remarkable untold story of a dramatic turning point in history, the exciting discovery of how the human brain works. In an unprecedented examination of how the secrets of the brain were revealed in seventeenth-century England, award-winning author Carl Zimmer tells an extraordinary tale that unfurls against a deadly backdrop of civil war, plague, and the Great Fire of London. At the beginning of that turbulent century, no one knew how the brain worked or even what it looked like intact. By the century's close, the science of the brain had taken root, helping to overturn many of the most common misconceptions and dominant philosophies about man, God, and the universe. Presiding over the rise of this new scientific paradigm was the founder of modern neurology, Thomas Willis, a fascinating, sympathetic, even heroic figure who stands at the center of an extraordinary group of scientists and philosophers known as the Oxford circle. Chronicled here in vivid detail are their groundbreaking revelations and often gory experiments that first enshrined the brain as the chemical engine of reason, emotion, and madness, indeed as the very seat of the human soul. Called 'as fine a science essayist as we have' by The New York Times, Zimmer tells the story of this scientific revolution through the lives of a colorful array of alchemists, mystics, utopians, spies, revolutionaries, and kings. He recreates the religious, ethical, and scientific struggles involved in the pioneering autopsies of the brain carried out by Thomas Willis; the discovery of the circulation of blood by William Harvey and his flight from London with his besieged king, Charles I; René Descartes's persecution by Catholics and Protestants alike for his views of the brain and soul; and the experiments and personal dramas of gifted men who forever changed the way science is practiced as they simultaneously upended our view of our human selves and our place in the world. In this distant mirror to our own time of continuing scientific revolution and worldwide social upheaval, Zimmer brings to life the painstaking, innovative discoveries of Willis and his contemporaries, the taproots of the amazing work of today's neuroscientists, who continue to explore the brain, revealing the hidden workings of emotions, memories, and consciousness. Graced with beautiful illustrations by Christopher Wren, Soul Made Flesh conveys a contagious appreciation for the wonder of the brain, its structure, its many marvelous functions, and the implications for human identity, mind, and morality. It is the definitive history of the dawn of a world-changing science and attitude, the age of the brain and modern consciousness.

A "New York Times" - bestselling author presents the true story of a pivotal moment in modern history when a group of strange, tormented geniuses--Isaac Newton chief among them--invented science and remade our understanding of the world.

The modern materialist approach to life has conspicuously failed to explain such central mind-related features of our world as consciousness, intentionality, meaning, and value. This failure to account for something so integral to nature as mind, argues philosopher Thomas Nagel, is a major problem, threatening to unravel the entire naturalistic world picture, extending to biology, evolutionary theory, and cosmology. Since minds are features of biological systems that have developed through evolution, the standard materialist version of evolutionary biology is fundamentally incomplete. And the cosmological history that led to the origin of life and the coming into existence of the conditions for evolution cannot be a merely materialist history, either. An adequate conception of nature would have to explain the appearance in the universe of materially irreducible conscious minds, as such. Nagel's skepticism is not based on religious belief or on a belief in any definite alternative. In Mind and Cosmos, he does suggest that if the materialist account is wrong, then principles of a different kind may also be at work in the history of nature, principles of the growth of order that are in their logical form teleological rather than mechanistic. In spite of the great achievements of the physical sciences, reductive materialism is a world view ripe for displacement. Nagel shows that to recognize its limits is the first step in looking for alternatives, or at least in being open to their possibility.--Publisher description.

"Totem and Taboo" is a collection of four essays by Sigmund Freud that were published together in German in 1913. Freud sought to apply his theories of psychoanalysis to the study of anthropology and early human history. The four essays cover a wide range of topics. In "The Horror of Incest", Freud examines the varied and common rules in primitive cultures that limit contact between members of the same family. In "Taboo and Emotional Ambivalence," Freud posits that primitive cultures and their attitudes about magical objects are similar to the behavior of people with neurotic psychological conditions in the modern world. In "Animism, Magic and the Omnipotence of Thought," Freud draws comparisons between the primitive belief in magic and magical animals to obsessive and compulsive disorders. Finally, in "The Return of Totemism in Childhood," Freud, influenced by one of Charles Darwin's theories about the male-dominated arrangement of early human societies, looks for parallels with his own Oedipus complex theory in the structure of primitive cultures. A classic and influential work of early psychoanalysis, "Totem and Taboo" is an important read for students of both psychology and social anthropology.

The Case for Mars makes living in space seem more possible than ever in this updated 25th anniversary edition, featuring the latest information on the planet's exploration and the drive to send humans there. Since the beginning of human history, Mars has been an alluring dream—the stuff of legends, gods, and mystery. The planet most like ours, it had long been thought impossible to reach, let alone explore and inhabit. But that is changing fast. In February 2021, the American rover Perseverance will touch down on Mars. Equipped with a powerful suite of scientific instruments—including some that will attempt to make oxygen from the Martian atmosphere—the rover also carries a helicopter that will take spectacular panoramic movies from the air. Most exciting of all, a spectrometer onboard may find evidence of fossils left behind by microbes millions of years ago, when the planet was warm and wet, proving at last that life on Earth is not unique, but a general phenomenon in the universe. Meanwhile, in Boca Chica, Texas, Elon Musk’s SpaceX has created a shipyard that is building and testing the vessels that will take humans to Mars before this decade is out. Leading space exploration expert Robert Zubrin crafted the daring blueprint for humanity’s reach to the Red Planet twenty-five years ago, when he first published The Case for Mars . Now, in this updated edition, he looks to the future once more to describe how—in an era when the American space program and private companies like SpaceX are racing to send astronauts to Mars—our first colonies there are imminent. In the grand tradition of successful explorers, Zubrin calls for a travel-light and live-off-the-land approach to Martian settlement. He explains how scientists can use present-day technology to send humans to Mars, produce fuel and oxygen on the planet’s surface with its own natural resources, build bases and communities, and one day, terraform—or alter the atmosphere of the planet in order to pave the way for sustainable life. As a landmark new mission opens the decisive campaign to take humans to the Red Planet, Zubrin lays out a comprehensive plan to build life on a new world.

A deluxe, two-volume, extensively illustrated edition of the best-selling history of the world chronicles a rich panorama of human achievement and the search for knowledge in fields ranging from geography to medicine, art to zoology.

Since its inception in 1915, the Best American series has become the premier annual showcase for the country's finest short fiction and nonfiction. For each volume, a series editor reads pieces from hundreds of periodicals, then selects between fifty and a hundred outstanding works. That selection is pared down to the twenty or so very best pieces by a guest editor who is widely recognized as a leading writer in his or her field. This unique system has helped make the Best American series the most respected -- and most popular -- of its kind. The Best American Science and Nature Writing 2004, edited by Steven Pinker, is another "provocative and thoroughly enjoyable [collection] from start to finish" (Publishers Weekly). Here is the best and newest on science and nature: the psychology of suicide terrorism, desperate measures in surgery, the weird world of octopuses, Sex Week at Yale, the linguistics of click languages, the worst news about cloning, and much more.

Over the past few decades there has been a revolution in terms of who controls knowledge and information. This rapid change has imperilled the way we think. Without pausing to consider the cost, the world has rushed to embrace the products and services of four titanic corporations. We shop with Amazon; socialise on Facebook; turn to Apple for entertainment; and rely on Google for information. These firms sell their efficiency and purport to make the world a better place, but what they have done instead is to enable an intoxicating level of daily convenience. As these companies have expanded, marketing themselves as champions of individuality and pluralism, their algorithms have pressed us into conformity and laid waste to privacy. They have produced an unstable and narrow culture of misinformation, and put us on a path to a world without private contemplation, autonomous thought, or solitary introspection - a world without mind. In order to restore our inner lives, we must avoid being co-opted by these gigantic companies, and understand the ideas that underpin their success. Elegantly tracing the intellectual history of computer science - from the Descartes and the enlightenment to Alan Turing to Stuart Brand and the hippie origins of today's Silicon Valley - Foer exposes the dark underpinnings of our most idealistic dreams for technology. The corporate ambitions of Google, Facebook, Apple, and Amazon, he argues, are trampling longstanding liberal values, especially intellectual property and privacy. This is a nascent stage in the total automation and homogenization of social, political, and intellectual life. By reclaiming our private authority over how we intellectually engage with the world, we have the power to stem the tide. At stake is nothing less than who we are, and what we will become. There have been monopolists in the past but today's corporate giants have far more nefarious aims. They're monopolists who want access to every facet of our identities and influence over every corner of our decision-making. Until now few have grasped the sheer scale of the threat. Foer explains not just the looming existential crisis but the imperative of resistance.

A vibrant cultural history investigating pandemics and vaccines, by bestselling author and historian Simon Schama Cities and countries engulfed by panic and death, desperate for vaccines but fearful of what inoculation may bring. This is what the world has just gone through with Covid-19. But as Simon Schama shows in his epic history of vulnerable humanity caught between the terror of contagion and the ingenuity of science, it has happened before. Characteristically, Schama's message is delivered through gripping, page-turning stories set in the eighteenth and nineteenth centuries: smallpox strikes London; cholera hits Paris; plague comes to India. Threading through the scenes of terror, suffering and hope - in hospitals and prisons, palaces, and slums - are an unforgettable cast of characters: a philosopher-playwright burning up with smallpox in a country chateau; a vaccinating doctor paying house calls in Halifax; a woman doctor in south India driving her inoculator-carriage through the stricken streets as dead monkeys drop from the trees. But we are also in the labs when great, life-saving breakthroughs happen, in Paris, Hong Kong, and Mumbai. At the heart of it all is an unsung hero: Waldemar Haffkine, a gun-toting Jewish student in Odesa turned microbiologist at the Pasteur Institute, hailed in England as "the saviour of mankind" for vaccinating millions against cholera and bubonic plague in British India while being cold-shouldered by the medical establishment of the Raj. Creator of the world's first mass production line of vaccines in Mumbai, he is tragically brought down in an act of shocking injustice. Foreign Bodies crosses borders between east and west, Asia and Europe, the worlds of rich and poor, politics and science. Its thrilling story carries with it the credo of its author on the interconnectedness of humanity and nature; of the powerful and the people. Ultimately, Schama says, as we face the challenges of our times together, "there are no foreigners, only familiars."

Unabridged declassified value reproduction of The Los Alamos Primer by Robert Serber, in full color with all censor markings. This is the booklet given to new workers at Los Alamos during World War II, to catch them up on how to build a practical fission bomb. The Primer was driven by Robert Oppenheimer asking his protégé Robert Serber to summarize all knowledge and possible solutions known as of April 1943 in a series of lectures. Serber did such an excellent job that the notes from the series was turned into The Los Alamos Primer. Serber was known as an expert that bridged theory and reality, and so was also chosen to be one of the first Americans to enter Hiroshima and Nagasaki to assess the atomic damage in 1945.

The former dean of the Yale School of Management and Undersecretary of Commerce in the Clinton administration chronicles the 1971 August meeting at Camp David, where President Nixon unilaterally ended the last vestiges of the gold standard--breaking the link between gold and the dollar--transforming the entire global monetary system. Over the course of three days--from August 13 to 15, 1971--at a secret meeting at Camp David, President Richard Nixon and his brain trust changed the course of history. Before that weekend, all national currencies were valued to the U.S. dollar, which was convertible to gold at a fixed rate. That system, established by the Bretton Woods Agreement at the end of World War II, was the foundation of the international monetary system that helped fuel the greatest expansion of middle-class prosperity the world has ever seen. In making his decision, Nixon shocked world leaders, bankers, investors, traders and everyone involved in global finance. Jeffrey E. Garten argues that many of the roots of America's dramatic retrenchment in world affairs began with that momentous event that was an admission that America could no longer afford to uphold the global monetary system. It opened the way for massive market instability and speculation that has plagued the world economy ever since, but at the same time it made possible the gigantic expansion of trade and investment across borders which created our modern era of once unimaginable progress. Based on extensive historical research and interviews with several participants at Camp David, and informed by Garten's own insights from positions in four presidential administrations and on Wall Street, Three Days at Camp David chronicles this critical turning point, analyzes its impact on the American economy and world markets, and explores its ramifications now and for the future.

"Weinberg takes us across centuries from ancient Miletus to medieval Baghdad and Oxford, from Plato's Academy and the Museum of Alexandria to the cathedral school of Chartres and the Royal Society of London. He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world--they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged"--Amazon.com ; Presents a commentary on the history of science that examines historic clashes and collaborations between science and the competing realms of religion, technology, poetry, mathematics, and philosophy

Why are objectivity and reason characterized as male and subjectively and feeling as female? How does this characterization affect the goals and methods of scientific enquiry? This groundbreaking work explores the possibilities of a gender-free science and the conditions that could make such a possibility a reality. "Keller’s book opens up a whole new range of ideas for anyone who cares to think about the history of science, that is, the history of the modern world. . . Let us be glad to be in times when such a sparkling, innovative. . . book can be produced, a book to start all of us thinking in new directions.”--Ian Hacking, New Republic "A brilliant and sensitive undertaking that does credit not only to feminist scholarship but, in the end, to science as well.”--Barbara Ehrenreich, Mother Jones "This book represents the expression of a particular feminist perspective made all the more compelling by Keller’s evident commitment to and understanding of science. As a lively and important contribution to the scholarship of science, it will undoubtedly stimulate argument and controversy.”--Helen Longino, Texas Humanist "Provocative arguments, presented with authority.”-- Kirkus Reviews "Consistently thoughtful, provocative, and interconnected. . . A well-made book that will be useful in upper-level undergraduate and graduate women’s studies, philosophy, and history of science.”--E.C. Patterson, Choice "Written with grace and clarity, [this book] will stand as an important contribution to feminist theory, to the sociology of knowledge and to the continuing critique of the established scientific method.”--Lillian B. Rubin "A powerful book.”--Jessie Bernard
