From the majestic Bengal tiger to the domesticated Siamese comes a meditation on cats from the bestselling author of  The Hidden Life of Dogs  and  The Social Lives of Dogs   From as far back in time as the disappearance of the dinosaurs, cats have occupied an important place in our evolutionary, social, and cultural history. The family of the cat is as diverse as it is widespread, ranging from the lions, tigers, and pumas of the African and Asian wilds to the domesticated cats of our homes, zoos, and circuses.   When she witnesses her housecat, Rajah, effortlessly scare off two fully-grown deer, acclaimed anthropologist Elizabeth Marshall Thomas starts studying the links that bind the feline family together. Immersing herself in the subtle differences of their social orders, feeding behaviors, and means of communication, Thomas explores the nature of the cat, both wild and domestic, and the resilient streak that has ensured its survival over thousands of years. |

“One of the best popular accounts of how Einstein and his followers have been trying to explain the universe for decades ” ( Kirkus Reviews , starred review).   Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. This has driven their work to unveil the universe’s surprising secrets even further, and many believe more wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, an astrophysicist brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma.   Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics—yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable.   Still, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory.   In the midst of a momentous transformation in modern physics, as scientists look farther and more clearly into space than ever before, The Perfect Theory exposes the greater relevance of general relativity, showing us where it started, where it has led—and where it can still take us.   |

“ Why We Sleep is an important and fascinating book…Walker taught me a lot about this basic activity that every person on Earth needs. I suspect his book will do the same for you.” —Bill Gates A New York Times bestseller and international sensation, this “stimulating and important book” ( Financial Times ) is a fascinating dive into the purpose and power of slumber. With two appearances on CBS This Morning and Fresh Air 's most popular interview of 2017, Matthew Walker has made abundantly clear that sleep is one of the most important but least understood aspects of our life. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when it is absent. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remains more elusive. Within the brain, sleep enriches a diversity of functions, including our ability to learn, memorize, and make logical decisions. It recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite. Dreaming creates a virtual reality space in which the brain melds past and present knowledge, inspiring creativity. In this “compelling and utterly convincing” ( The Sunday Times ) book, preeminent neuroscientist and sleep expert Matthew Walker provides a revolutionary exploration of sleep, examining how it affects every aspect of our physical and mental well-being. Charting the most cutting-edge scientific breakthroughs, and marshalling his decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood and energy levels, regulate hormones, prevent cancer, Alzheimer’s and diabetes, slow the effects of aging, and increase longevity. He also provides actionable steps towards getting a better night’s sleep every night. Clear-eyed, fascinating, and accessible, Why We Sleep is a crucial and illuminating book. Written with the precision of Atul Gawande, Andrew Solomon, and Sherwin Nuland, it is “recommended for night-table reading in the most pragmatic sense” ( The New York Times Book Review ). |

A New York Times Bestseller A Washington Post Notable Nonfiction Book of 2020 Named a Best Book of 2020 by NPR   “A fascinating scientific, cultural, spiritual and evolutionary history of the way humans breathe—and how we’ve all been doing it wrong for a long, long time.” —Elizabeth Gilbert, author of Big Magic and Eat Pray Love No matter what you eat, how much you exercise, how skinny or young or wise you are, none of it matters if you’re not breathing properly. There is nothing more essential to our health and well-being than breathing: take air in, let it out, repeat twenty-five thousand times a day. Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences. Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren’t found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of São Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe. Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is. Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again. |

NATIONAL BESTSELLER NEW YORK TIMES BESTSELLER   A world-leading expert shares her amazing story of discovering the communication that exists between trees, and shares her own story of family and grief. Suzanne Simard is a pioneer on the frontier of plant communication and intelligence; she’s been compared to Rachel Carson, hailed as a scientist who conveys complex, technical ideas in a way that is dazzling and profound. Her work has influenced filmmakers (the Tree of Souls in James Cameron’s Avatar ), and her TED talks have been viewed by more than 10 million people worldwide.      Now, in her first book, Simard brings us into her world, the intimate world of the trees, in which she brilliantly illuminates the fascinating and vital truths—that trees are not simply the source of timber or pulp but are a complicated, interdependent circle of life; that forests are social, cooperative creatures connected through underground networks by which trees communicate their vitality and vulnerabilities with communal lives not that different from our own.      Simard describes up close—in revealing and accessible ways—how trees, living side by side for hundreds of years, have evolved; how they perceive one another, learn and adapt their behaviors, recognize neighbors, and remember the past; how they have agency about their future; how they elicit warnings and mount defenses, compete and cooperate with one another with sophistication: characteristics previously ascribed to human intelligence, traits that are the essence of civil societies. And, at the center of it all, the Mother Trees: the mysterious, powerful forces that connect and sustain the others that surround them.Simard, born and raised in the rain forests of British Columbia, spent her days as a child cataloging the trees from the forest; she came to love and respect them and embarked on a journey of discovery and struggle. Her powerful story is one of love and loss, of observation and change, of risk and reward. And it is a testament to how deeply human scientific inquiry exists beyond data and technology: it’s about understanding who we are and our place in the world. In her book, as in her groundbreaking research, Simard proves the true connectedness of the Mother Tree to the forest, nurturing it in the profound ways that families and humansocieties nurture one another, and how these inseparable bonds enable all our survival. |

"Explores how industry has manipulated our most deep-seated survival instincts." —David Perlmutter, MD, Author, #1 New York Times bestseller,  Grain Brain  and  Brain Maker The New York Times –bestselling author of Fat Chance reveals the corporate scheme to sell pleasure, driving the international epidemic of addiction, depression, and chronic disease.   While researching the toxic and addictive properties of sugar for his New York Times bestseller Fat Chance , Robert Lustig made an alarming discovery—our pursuit of happiness is being subverted by a culture of addiction and depression from which we may never recover.             Dopamine is the “reward” neurotransmitter that tells our brains we want more; yet every substance or behavior that releases dopamine in the extreme leads to addiction. Serotonin is the “contentment” neurotransmitter that tells our brains we don’t need any more; yet its deficiency leads to depression. Ideally, both are in optimal supply. Yet dopamine evolved to overwhelm serotonin—because our ancestors were more likely to survive if they were constantly motivated—with the result that constant desire can chemically destroy our ability to feel happiness, while sending us down the slippery slope to addiction. In the last forty years, government legislation and subsidies have promoted ever-available temptation (sugar, drugs, social media, porn) combined with constant stress (work, home, money, Internet), with the end result of an unprecedented epidemic of addiction, anxiety, depression, and chronic disease. And with the advent of neuromarketing, corporate America has successfully imprisoned us in an endless loop of desire and consumption from which there is no obvious escape.             With his customary wit and incisiveness, Lustig not only reveals the science that drives these states of mind, he points his finger directly at the corporations that helped create this mess, and the government actors who facilitated it, and he offers solutions we can all use in the pursuit of happiness, even in the face of overwhelming opposition. Always fearless and provocative, Lustig marshals a call to action, with seminal implications for our health, our well-being, and our culture. |

Given the fact that there are perhaps 400 billion stars in our Galaxy alone, and perhaps 400 billion galaxies in the Universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?  In this second, significantly revised and expanded edition of his widely popular book, Webb discusses in detail the (for now!) 75 most cogent and intriguing solutions to Fermi's famous paradox: If the numbers strongly point to the existence of extraterrestrial civilizations, why have we found no evidence of them? Reviews from the first edition:  "Amidst the plethora of books that treat the possibility of extraterrestrial intelligence, this one by Webb … is outstanding. … Each solution is presented in a very logical, interesting, thorough manner with accompanying explanations and notes that the intelligent layperson can understand. Webb digs into the issues … by considering a very broad set of in-depth solutions that he addresses through an interesting and challenging mode of presentation that stretches the mind. … An excellent book for anyone who has ever asked ‘Are we alone?’." (W. E. Howard III, Choice, March, 2003) "Fifty ideas are presented … that reveal a clearly reasoned examination of what is known as ‘The Fermi Paradox’. … For anyone who enjoys a good detective story, or using their thinking faculties and stretching the imagination to the limits … ‘Where is everybody’ will be enormously informative and entertaining. … Read this book, and whatever your views are about life elsewhere in the Universe, your appreciation for how special life is here on Earth will be enhanced! A worthy addition to any personal library." (Philip Bridle, BBC Radio, March, 2003) Since gaining a BSc in physics from the University of Bristol and a PhD in theoretical physics from the University of Manchester, Stephen Webb has worked in a variety of universities in the UK. He is a regular contributor to the Yearbook of Astronomy series and has published an undergraduate textbook on distance determination in astronomy and cosmology as well as several popular science books. His interest in the Fermi paradox combines lifelong interests in both science and science fiction. |

From a star theoretical physicist, a journey into the world of particle physics and the cosmos -- and a call for a more just practice of science.  In The Disordered Cosmos , Dr. Chanda Prescod-Weinstein shares her love for physics, from the Standard Model of Particle Physics and what lies beyond it, to the physics of melanin in skin, to the latest theories of dark matter -- all with a new spin informed by history, politics, and the wisdom of Star Trek. One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly non-traditional, and grounded in Black feminist traditions. Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, sexism, and other dehumanizing systems. She lays out a bold new approach to science and society that begins with the belief that we all have a fundamental right to know and love the night sky. The Disordered Cosmos dreams into existence a world that allows everyone to experience and understand the wonders of the universe. |

Almost 200 million human beings, mostly civilians, have died in wars over the last century, and there is no end of slaughter in sight. The Most Dangerous Animal asks what it is about human nature that makes it possible for human beings to regularly slaughter their own kind. It tells the story of why all human beings have the potential to be hideously cruel and destructive to one another. Why are we our own worst enemy? The book shows us that war has been with us---in one form or another---since prehistoric times, and looking at the behavior of our close relatives, the chimpanzees, it argues that a penchant for group violence has been bred into us over millions of years of biological evolution. The Most Dangerous Animal takes the reader on a journey through evolution, history, anthropology, and psychology, showing how and why the human mind has a dual nature: on the one hand, we are ferocious, dangerous animals who regularly commit terrible atrocities against our own kind, on the other, we have a deep aversion to killing, a horror of taking human life. Meticulously researched and far-reaching in scope and with examples taken from ancient and modern history, The Most Dangerous Animal delivers a sobering lesson for an increasingly dangerous world. |

As a botanist, Robin Wall Kimmerer has been trained to ask questions of nature with the tools of science. As a member of the Citizen Potawatomi Nation, she embraces the notion that plants and animals are our oldest teachers. In Braiding Sweetgrass , Kimmerer brings these two lenses of knowledge together to take us on “a journey that is every bit as mythic as it is scientific, as sacred as it is historical, as clever as it is wise” (Elizabeth Gilbert). Drawing on her life as an indigenous scientist, and as a woman, Kimmerer shows how other living beings—asters and goldenrod, strawberries and squash, salamanders, algae, and sweetgrass—offer us gifts and lessons, even if we've forgotten how to hear their voices. In reflections that range from the creation of Turtle Island to the forces that threaten its flourishing today, she circles toward a central argument: that the awakening of ecological consciousness requires the acknowledgment and celebration of our reciprocal relationship with the rest of the living world. For only when we can hear the languages of other beings will we be capable of understanding the generosity of the earth, and learn to give our own gifts in return. |

Originally published in 1998, this updated edition has a brand-new cover and interior design, with a new foreword by Alexandra Morton. Billy Proctor was born in 1934 and has spent his entire life in a remote coastal community called Echo Bay, BC on an island off northern Vancouver Island. Proctor has always done the time-honoured work of generations of upcoast men—hand-logging, fishing, clam digging, repairing boats, beachcombing. But Billy eventually began to notice that the thriving runs of Pacific salmon, oolichans, and herring that he remembers from his early years were vanishing—some to near extinction—and he understood that it was time to take action. Heart of the Raincoast is the fascinating story of Billy Proctor’s life, and the wealth of knowledge and understanding that can only be gained from living in such close proximity to nature. The writing is funny, touching and honest—and offers an engaging insider’s view not only of the salmon, whales, eagles and independent people who populate Canada’s wild and lovely coastal rainforest, but on what we need to do to keep it as nature intended. |

Former New York Times reporter Alex Berenson turns to the most controversial aspect of the coronavirus epidemic - vaccinations - in the fourth installment of the best-selling Unreported Truths series. When Pfizer and Moderna announced in November that their mRNA vaccines had cut coronavirus infections by 95 percent with few side effects, the world rejoiced. But in the months since, the truth has proven to be far more complex. Countries like Israel and Britain have seen sharp short-term spikes in coronavirus cases and deaths following the beginning of mass vaccination campaigns. Many people have reported severe side effects after being vaccinated. Yet media outlets and public health authorities have largely ignored any potential risks as they encourage everyone, even young people at almost no risk from Covid, to be vaccinated. Berenson offers a more nuanced perspective, explaining both the risks and benefits of the new Covid vaccines - with a focus on the risks, since those have not been covered. Like earlier Unreported Truths booklets, Part 4 draws on verifiable and checkable sources, including government documents, scientific papers, and news articles. It will give you a new perspective on the pros and cons of these new vaccines - and the truthful and accurate information you will not find anywhere else. Please note: This ebook contains only the fourth section of Unreported Truths. The earlier sections are available separately. |

An instant New York Times Bestseller! “Unreasonably entertaining....reveals how geometric thinking can allow for everything from fairer American elections to better pandemic planning.” - The New York Times   From the New York Times -bestselling author of How Not to Be Wrong— himself a world-class geometer—a far-ranging exploration of the power of geometry, which turns out to help us think better about practically everything. How should a democracy choose its representatives? How can you stop a pandemic from sweeping the world? How do computers learn to play Go, and why is learning Go so much easier for them than learning to read a sentence? Can ancient Greek proportions predict the stock market? (Sorry, no.) What should your kids learn in school if they really want to learn to think? All these are questions about geometry. For real. If you're like most people, geometry is a sterile and dimly remembered exercise you gladly left behind in the dust of ninth grade, along with your braces and active romantic interest in pop singers. If you recall any of it, it's plodding through a series of miniscule steps only to prove some fact about triangles that was obvious to you in the first place. That's not geometry. Okay, it is geometry, but only a tiny part, which has as much to do with geometry in all its flush modern richness as conjugating a verb has to do with a great novel. Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. The word "geometry"comes from the Greek for "measuring the world." If anything, that's an undersell. Geometry doesn't just measure the world—it explains it. Shape shows us how. |

#1  NEW YORK TIMES BESTSELLER • The world-famous cosmologist and author of A Brief History of Time leaves us with his final thoughts on the biggest questions facing humankind. “Hawking’s parting gift to humanity . . . a book every thinking person worried about humanity’s future should read.”—NPR NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Forbes • The Guardian • Wired Stephen Hawking was the most renowned scientist since Einstein, known both for his groundbreaking work in physics and cosmology and for his mischievous sense of humor. He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live. In later life he could communicate only by using a few facial muscles, but he continued to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe’s greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet—including climate change, the threat of nuclear war, and the development of artificial intelligence—he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history. Featuring a foreword by Eddie Redmayne, who won an Oscar playing Stephen Hawking, an introduction by Nobel Laureate Kip Thorne, and an afterword from Hawking’s daughter, Lucy,  Brief Answers to the Big Questions is a brilliant last message to the world. Praise for Brief Answers to the Big Questions “[Hawking is] a symbol of the soaring power of the human mind.” — The Washington Post “Hawking’s final message to readers . . . is a hopeful one.” —CNN “Brisk, lucid peeks into the future of science and of humanity.” —The Wall Street Journal “Hawking pulls no punches on subjects like machines taking over, the biggest threat to Earth, and the possibilities of intelligent life in space.” —Quartz “Effortlessly instructive, absorbing, up to the minute and—where it matters—witty.” —The Guardian “This beautiful little book is a fitting last twinkle from a new star in the firmament above.” — The Telegraph |

NEW YORK TIMES BESTSELLER • From the author of The Eighty-Dollar Champion, the remarkable story of the heroic rescue of priceless horses in the closing days of World War II WINNER OF THE PEN AWARD FOR RESEARCH NONFICTION In the chaotic last days of the war, a small troop of battle-weary American soldiers captures a German spy and makes an astonishing find—his briefcase is empty but for photos of beautiful white horses that have been stolen and kept on a secret farm behind enemy lines. Hitler has stockpiled the world’s finest purebreds in order to breed the perfect military machine—an equine master race. But with the starving Russian army closing in, the animals are in imminent danger of being slaughtered for food. With only hours to spare, one of the U.S. Army’s last great cavalrymen, Colonel Hank Reed, makes a bold decision—with General George Patton’s blessing—to mount a covert rescue operation. Racing against time, Reed’s small but determined force of soldiers, aided by several turncoat Germans, steals across enemy lines in a last-ditch effort to save the horses. Pulling together this multistranded story, Elizabeth Letts introduces us to an unforgettable cast of characters: Alois Podhajsky, director of the famed Spanish Riding School of Vienna, a former Olympic medalist who is forced to flee the bomb-ravaged Austrian capital with his entire stable in tow; Gustav Rau, Hitler’s imperious chief of horse breeding, a proponent of eugenics who dreams of genetically engineering the perfect warhorse for Germany; and Tom Stewart, a senator’s son who makes a daring moonlight ride on a white stallion to secure the farm’s surrender. A compelling account for animal lovers and World War II buffs alike, The Perfect Horse tells for the first time the full story of these events. Elizabeth Letts’s exhilarating tale of behind-enemy-lines adventure, courage, and sacrifice brings to life one of the most inspiring chapters in the annals of human valor. Praise for The Perfect Horse “Winningly readable . . . Letts captures both the personalities and the stakes of this daring mission with such a sharp ear for drama that the whole second half of the book reads like a WWII thriller dreamed up by Alan Furst or Len Deighton. . . . The right director could make a Hollywood classic out of this fairy tale.” — The Christian Science Monitor “Letts, a lifelong equestrienne, eloquently brings together the many facets of this unlikely, poignant story underscoring the love and respect of man for horses.” — Kirkus Reviews |

I wanted to know what they were experiencing, and why to us they feel so compelling, and so-close. This time I allowed myself to ask them the question that for a scientist was forbidden fruit: Who are you? Weaving decades of field observations with exciting new discoveries about the brain, Carl Safina's landmark book offers an intimate view of animal behavior to challenge the fixed boundary between humans and nonhuman animals. In Beyond Words , readers travel to Amboseli National Park in the threatened landscape of Kenya and witness struggling elephant families work out how to survive poaching and drought, then to Yellowstone National Park to observe wolves sort out the aftermath of one pack's personal tragedy, and finally plunge into the astonishingly peaceful society of killer whales living in the crystalline waters of the Pacific Northwest. Beyond Words brings forth powerful and illuminating insight into the unique personalities of animals through extraordinary stories of animal joy, grief, jealousy, anger, and love. The similarity between human and nonhuman consciousness, self-awareness, and empathy calls us to re-evaluate how we interact with animals. Wise, passionate, and eye-opening at every turn, Beyond Words is ultimately a graceful examination of humanity's place in the world. |

“The bard of biological weapons captures the drama of the front lines.”— Richard Danzig, former secretary of the navy The first major bioterror event in the United States-the anthrax attacks in October 2001-was a clarion call for scientists who work with “hot” agents to find ways of protecting civilian populations against biological weapons. In The Demon in the Freezer,  his first nonfiction book since The Hot Zone, a #1 New York Times bestseller, Richard Preston takes us into the heart of Usamriid, the United States Army Medical Research Institute of Infectious Diseases at Fort Detrick, Maryland, once the headquarters of the U.S. biological weapons program and now the epicenter of national biodefense. Peter Jahrling, the top scientist at Usamriid, a wry virologist who cut his teeth on Ebola, one of the world’s most lethal emerging viruses, has ORCON security clearance that gives him access to top secret information on bioweapons. His most urgent priority is to develop a drug that will take on smallpox-and win. Eradicated from the planet in 1979 in one of the great triumphs of modern science, the smallpox virus now resides, officially, in only two high-security freezers-at the Centers for Disease Control in Atlanta and in Siberia, at a Russian virology institute called Vector. But the demon in the freezer has been set loose. It is almost certain that illegal stocks are in the possession of hostile states, including Iraq and North Korea. Jahrling is haunted by the thought that biologists in secret labs are using genetic engineering to create a new superpox virus, a smallpox resistant to all vaccines. Usamriid went into a state of Delta Alert on September 11 and activated its emergency response teams when the first anthrax letters were opened in New York and Washington, D.C. Preston reports, in unprecedented detail, on the government’ s response to the attacks and takes us into the ongoing FBI investigation. His story is based on interviews with top-level FBI agents and with Dr. Steven Hatfill. Jahrling is leading a team of scientists doing controversial experiments with live smallpox virus at CDC. Preston takes us into the lab where Jahrling is reawakening smallpox and explains, with cool and devastating precision, what may be at stake if his last bold experiment fails. |

“Rovelli is a genius and an amazing communicator… This is the place where science comes to life.” ― Neil Gaiman “One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book” ―John Banville, The Wall Street Journal A startling new look at quantum theory, from the New York Times bestselling author of Seven Brief Lessons on Physics and The Order of Time . One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland , he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it. |

The Golden Spruce is the story of a glorious natural wonder, the man who destroyed it, and the fascinating, troubling context in which his act took place. A tree with luminous glowing needles, the golden spruce was unique and, biologically speaking, should never have reached maturity; Grant Hadwin, the man who cut it down, was passionate, extraordinarily well-suited to wilderness survival, and to some degree unbalanced. But as John Vaillant shows, the extraordinary tree stood at the intersection of contradictory ways of looking at the world; the conflict between them is one reason it was destroyed. Taking in history, geography, science and spirituality, this book raises some of the most pressing questions facing society today. The golden spruce stood in the Queen Charlotte Islands (Haida Gwaii), an unusually rich ecosystem where the normal lines between species blur. Without romanticizing, Vaillant shows that this understanding is typified by the Haida, the native people who have lived there for millennia, and for whom the golden spruce was an integral part of their history and mythology. But seen a different way, the golden spruce stood in block 6 of Tree Farm License 39. Grant Hadwin had worked as a remote scout for timber companies. But over time Hadwin was pushed into a paradox: the better he was at his job, the more the world he loved was destroyed. On January 20, 1997, with the temperature near zero, Hadwin swam across the Yakoun River with a chainsaw. He tore into the golden spruce, leaving it so unstable that the first wind would push it over. A few weeks later, Hadwin set off in a kayak across the treacherous Hecate Strait to face court charges. He has not been heard from since. Vaillant describes Hadwin’s actions in engrossing detail, but also provides the complex environmental, political and economic context in which they took place. The Golden Spruce forces one to ask: can the damage our civilization exacts on the natural world be justified? |

Comment expliquer qu’une civilisation qui connaît la mécanique quantique, qui a mis les pieds sur la Lune et qui a les moyens de bouleverser, à elle seule, le climat de la planète n’ait pu faire mieux, pour contrer un nouveau virus, que d’enfermer sa population à double tour pendant des mois, mesure digne du Moyen Âge, créant au passage la plus grande contraction économique de son histoire ? Bien sûr, le virus SRAS-CoV-2, responsable de la COVID-19, dont le taux de mortalité est nettement supérieur à celui de la grippe, représente partout sur la planète une très sérieuse menace à la santé. Toutefois, ce n’est ni la première ni la pire des pandémies que l’humanité ait eu à affronter au cours de son histoire récente. Normand Mousseau commence par clarifier l’état du savoir scientifique au sujet de ce virus et de son mode de transmission. Surtout, il propose ensuite une réflexion critique sur les enjeux profonds que cette crise sanitaire a révélés dans notre manière de faire face à l’imprévu. On y voit des experts scientifiques enfermés dans leur spécialité et plus prompts à construire des modèles théoriques qu’à mener des études sur le terrain. Des journalistes qui relaient cette information sans prendre le temps de la critiquer ou de la remettre en contexte. Un appareil d’État lourdement centralisé et laissé exsangue à la suite des réformes des dernières années dans le domaine de la santé. Et des politiciens en mal d’approbation qui profitent de toutes les tribunes pour projeter une image paternaliste, infantilisant le public et justifiant au nom de l’état d’urgence des mesures qui vont à l’encontre de nos traditions démocratiques. La pandémie occasionnée par la COVID-19 génère une très lourde facture, économique et humaine, qui retombe surtout sur les épaules des jeunes, des femmes et des plus démunis. Oui, il y avait moyen de faire autrement sans sombrer dans l’insouciance ou les théories du complot, nous dit Normand Mousseau. Et nous pouvons nous donner les outils nécessaires pour mieux traverser cette crise et celles que l’avenir ne manquera pas de nous apporter. Nous y arriverons à condition de ne pas nous laisser aveugler par la peur, et en choisissant collectivement une réponse rationnelle, humaine et généreuse pour tous nos concitoyens. |
