Pilote du bout du monde: souvenirs d'un pilote de brousse dans le Grand Nord
Par Dominique Prinet. 2022
Au cours des années 1960 et 1970, le Grand Nord canadien était en pleine effervescence. Dominique Prinet, alors jeune pilote…
de brousse, y a effectué des vols incroyables, lui qui a transporté, par tous les temps, des pêcheurs, des chasseurs et des trappeurs, des chercheurs d'or ou de pétrole, ainsi que des blessés et des malades nécessitant une évacuation d'urgence. C'était bien avant le GPS, quand les cartes se révélaient imprécises, les modes de communication, rudimentaires, et que les voyages du genre duraient des semainesUn dernier tour d'ambulance: récits d'un paramédic

Par Jason Roberts. 2024
From the bestselling author of A Sense of the World comes this dramatic, globe-spanning and meticulously-researched story of two scientific…
rivals and their race to survey all life on Earth.In the 18th century, two men dedicated their lives to the same daunting task: identifying and describing all life on Earth. Their approaches could not have been more different. Carl Linnaeus, a pious Swedish doctor with a huckster's flair, believed that life belonged in tidy, static categories. Georges-Louis de Buffon, an aristocratic polymath and keeper of France's royal garden, viewed life as a dynamic swirl of complexities. Both began believing their work to be difficult, but not impossible—how could the planet possibly hold more than a few thousand species? Stunned by life's diversity, both fell far short of their goal. But in the process they articulated starkly divergent views on nature, on humanity's role in shaping the fate of our planet and on humanity itself. The rivalry between these two unique, driven individuals created reverberations that still echo today. Linnaeus, with the help of acolyte explorers he called "apostles" (only half of whom returned alive), gave the world such concepts as mammal, primate and homo sapiens—but he also denied species change and promulgated racist pseudo-science. Buffon coined the term reproduction, formulated early prototypes of evolution and genetics, and argued passionately against prejudice. It was a clash that, during their lifetimes, Buffon seemed to be winning. But their posthumous fates would take a very different turn.With elegant, propulsive prose grounded in more than a decade of research, featuring appearances by Voltaire, Benjamin Franklin and Charles Darwin, bestselling author Jason Roberts tells an unforgettable true-life tale of intertwined lives and enduring legacies, tracing an arc of insight and discovery that extends across three centuries into the present day.Advanced Methods of Joint Inversion and Fusion of Multiphysics Data (Advances in Geological Science)
Par Michael S. Zhdanov. 2023
Different physical or geophysical methods provide information about distinctive physical properties of the objects, e.g., rock formations and mineralization. In…
many cases, this information is mutually complementary, which makes it natural for consideration in a joint inversion of the multiphysics data. Inversion of the observed data for a particular experiment is subject to considerable uncertainty and ambiguity. One productive approach to reducing uncertainty is to invert several types of data jointly. Nonuniqueness can also be reduced by incorporating additional information derived from available a priori knowledge about the target to reduce the search space for the solution. This additional information can be incorporated in the form of a joint inversion of multiphysics data.Generally established joint inversion methods, however, are inadequate for incorporating typical physical or geological complexity. For example, analytic, empirical, or statistical correlations between different physical properties may exist for only part of the model, and their specific form may be unknown. Features or structures that are present in the data of one physical method may not be present in the data generated by another physical method or may not be equally resolvable.This book presents and illustrates several advanced, new approaches to joint inversion and data fusion, which do not require a priori knowledge of specific empirical or statistical relationships between the different model parameters or their attributes. These approaches include the following novel methods, among others: 1) the Gramian method, which enforces the correlation between different parameters; 2) joint total variation functional or joint focusing stabilizers, e.g., minimum support and minimum gradient support constraints; 3) data fusion employing a joint minimum entropy stabilizer, which yields the simplest multiphysics solution that fits the multi-modal data. In addition, the book describes the principles of using artificial intelligence (AI) in solving multiphysics inverse problems. The book also presents in detail both the mathematical principles of these advanced approaches to joint inversion of multiphysics data and successful case histories of regional-scale and deposit-scale geophysical studies to illustrate their indicated advantages.The Milky Way: An Autobiography of Our Galaxy
Par Moiya McTier. 2022
In this approachable and fascinating biography of the galaxy, an astrophysicist and folklorist details everything humans have discovered—from the Milky…
Way's formation to its eventual death, and what else there is to learn about the universe we call home. After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other. They succumbed to their gravitational attraction, and the galaxy we know as the Milky Way was born. Since then, the galaxy has watched as dark energy pushed away its first friends, as humans mythologized its name and purpose, and as galactic archaeologists have worked to determine its true age (rude). The Milky Way has absorbed supermassive (an actual technical term) black holes, made enemies of a few galactic neighbors, and mourned the deaths of countless stars. Our home galaxy has even fallen in love. After all this time, the Milky Way finally feels that it's amassed enough experience for the juicy tell-all we've all been waiting for. Its fascinating autobiography recounts the history and future of the universe in accessible but scientific detail, presenting a summary of human astronomical knowledge thus far that is unquestionably out of this world. NAMED A BEST BOOK OF 2022 BY PUBLISHERS WEEKLY AND SCIENCENET NAMED A BEST AUDIOBOOK OF 2022 BY BOOKPAGELeft on Tenth: A Second Chance at Life: A Memoir
Par Delia Ephron. 2021
The bestselling, beloved writer of romantic comedies like You've Got Mail tells her own late-in-life love story in her "resplendent…
memoir," complete with a tragic second act and joyous resolution (Adriana Trigiani, bestselling author of The Good Left Undone). Delia Ephron had struggled through several years of heartbreak. She&’d lost her sister, Nora, and then her husband, Jerry, both to cancer. Several months after Jerry&’s death, she decided to make one small change in her life—she shut down his landline, which crashed her internet. She ended up in Verizon hell. She channeled her grief the best way she knew: by writing a New York Times op-ed. The piece caught the attention of Peter, a Bay Area psychiatrist, who emailed her to commiserate. Recently widowed himself, he reminded her that they had shared a few dates fifty-four years before, set up by Nora. Delia did not remember him, but after several weeks of exchanging emails and sixties folk songs, he flew east to see her. They were crazy, utterly, in love. But this was not a rom-com: four months later she was diagnosed with AML, a fierce leukemia. In Left on Tenth, Delia Ephron enchants as she seesaws us between tears and laughter, navigating the suicidal lows of enduring cutting-edge treatment and the giddy highs of a second chance at love. With Peter and her close girlfriends by her side, with startling clarity, warmth, and honesty about facing death, Ephron invites us to join her team of warriors and become believers ourselves.A "Most Anticipated Book of 2022" by TIME, Bustle, Parade, Publishers Weekly, Boston.comA "Best Memoir of 2022" by Marie ClaireA "Best Memoir of April" by Vanity FairTaking the Quantum Leap: The New Physics for Nonscientists

National Book AwardTaking the Quantum Leap entertainingly traces the history of physics from the observations of the early Greeks through the discoveries of Galileo and Newton to the dazzling theories of such scientists as Planck, Einstein, Bohr, and Bohm. This humanized view of science opens up the mind-stretching visions of how quantum mechanics, God, human thought, and will are related, and provides profound implications for our understanding of the nature of reality and our relationship to the cosmos.“The prose, indeed, is exhilarating, and exhibits a passion to explain—humorously . . . Wolf provides commendable explanations of visions and revisions of atomic models; he is fin, in particular, on the Uncertainty Principle . . . Enjoy the book for its bravura.” —Kirkus ReviewsThe Song of Our Scars: The Untold Story of Pain
Par Haider Warraich. 2022
A doctor&’s personal and unsparing account of how modern medicine&’s failure to understand pain has made care less effectiveIn The Song…
of Our Scars, physician Haider Warraich offers a bold reexamination of the nature of pain, not as a simple physical sensation, but as a cultural experience.Warraich, himself a sufferer of chronic pain, considers the ways our notions of pain have been shaped not just by science but by politics and power, by whose suffering mattered and whose didn&’t. He weaves a provocative history from the Renaissance, when pain transformed into a medical issue, through the racial legacy of pain tolerance, to the opiate epidemics of both the nineteenth and twenty-first centuries, to the cutting edge of present-day pain science. The conclusion is clear: only by reckoning with both pain&’s complicated history and its biology can today&’s doctors adequately treat their patients&’ suffering.Trenchant and deeply felt, The Song of Our Scars is an indictment of a broken system and a plea for a more holistic understanding of the human body.This book focuses in detail on data science and data analysis and emphasizes the importance of data engineering and data…
management in the design of big data applications. The author uses patterns discovered in a collection of big data applications to provide design principles for hypothesis generation, integrating big data processing and management, machine learning and data mining techniques. The book proposes and explains innovative principles for interpreting hypotheses by integrating micro-explanations (those based on the explanation of analytical models and individual decisions within them) with macro-explanations (those based on applied processes and model generation). Practical case studies are used to demonstrate how hypothesis-generation and -interpretation technologies work. These are based on “social infrastructure” applications like in-bound tourism, disaster management, lunar and planetary exploration, and treatment of infectious diseases. The novel methods and technologies proposed in Hypothesis Generation and Interpretation are supported by the incorporation of historical perspectives on science and an emphasis on the origin and development of the ideas behind their design principles and patterns. Academic investigators and practitioners working on the further development and application of hypothesis generation and interpretation in big data computing, with backgrounds in data science and engineering, or the study of problem solving and scientific methods or who employ those ideas in fields like machine learning will find this book of considerable interest.Optical Fiber Current and Voltage Sensors (Series in Fiber Optic Sensors)

Par Simon Badger, Johannes Henn, Jan Christoph Plefka, Simone Zoia. 2024
This open access book bridges a gap between introductory Quantum Field Theory (QFT) courses and state-of-the-art research in scattering amplitudes.…
It covers the path from basic definitions of QFT to amplitudes, which are relevant for processes in the Standard Model of particle physics. The book begins with a concise yet self-contained introduction to QFT, including perturbative quantum gravity. It then presents modern methods for calculating scattering amplitudes, focusing on tree-level amplitudes, loop-level integrands and loop integration techniques. These methods help to reveal intriguing relations between gauge and gravity amplitudes and are of increasing importance for obtaining high-precision predictions for collider experiments, such as those at the Large Hadron Collider, as well as for foundational mathematical physics studies in QFT, including recent applications to gravitational wave physics.These course-tested lecture notes include numerous exercises with solutions. Requiring only minimal knowledge of QFT, they are well-suited for MSc and PhD students as a preparation for research projects in theoretical particle physics. They can be used as a one-semester graduate level course, or as a self-study guide for researchers interested in fundamental aspects of quantum field theory.The Goldilocks Enigma: Why Is the Universe Just Right for Life?
Par Paul Davies. 2007
An acclaimed physicist and cosmologist considers the multiverse and more: &“Very readable indeed . . . This is Doctor Who, but for real.&” —TheGuardianThe…
Goldilocks Enigma is Paul Davies&’s eagerly awaited return to cosmology, the successor to his critically acclaimed bestseller The Mind of God. Here he tackles all the &“big questions,&” including the biggest of them all: Why does the universe seem so well adapted for life? In his characteristically clear and elegant style, Davies shows how recent scientific discoveries point to a perplexing fact: many different aspects of the cosmos, from the properties of the humble carbon atom to the speed of light, seem tailor-made to produce life. A radical new theory says it&’s because our universe is just one of an infinite number of universes, each one slightly different. Our universe is bio-friendly by accident—we just happened to win the cosmic jackpot. While this &“multiverse&” theory is compelling, it has bizarre implications, such as the existence of infinite copies of each of us and Matrix-like simulated universes. And it still leaves a lot unexplained. Davies believes there&’s a more satisfying solution to the problem of existence: the observations we make today could help shape the nature of reality in the remote past. If this is true, then life—and, ultimately, consciousness—aren&’t just incidental byproducts of nature, but central players in the evolution of the universe. Whether he&’s elucidating dark matter or dark energy, M-theory or the multiverse, Davies brings the leading edge of science into sharp focus, provoking us to think about the cosmos and our place within it in new and thrilling ways.Bailey's Remarkable Plan
