From the bestselling author of The Clockwork Universe and The Writing of the Gods , an “utterly delightful…hugely entertaining” ( Air Mail ) book about the eccentric Victorians who discovered dinosaur bones, leading to a whole new understanding of human history. In the early 1800s the natural world was a safe and cozy place, or so people believed. But then a twelve-year-old farm boy in Massachusetts stumbled on a row of fossilized three-toed footprints the size of dinner plates—the first dinosaur tracks ever found. Soon, in England, scientists unearthed enormous bones that reached as high as a man’s head. Outside of myths and fairy tales, no one had even imagined that creatures like three-toed giants had once lumbered across the land—nor dreamed that they could all have vanished, hundreds of millions years ago. In Dinosaurs at the Dinner Party , celebrated storyteller and historian Edward Dolnick leads us through a compelling true adventure as the paleontologists of the early 19th century puzzled their way through the fossil record to create the story of dinosaurs we know today. The tale begins with Mary Anning, a poor, uneducated woman who had a sixth sense for finding fossils buried deep inside cliffs; moves to William Buckland, an eccentric geologist who filled his home with specimens and famously pieced together a prehistoric scene from the fossil record inside a cave; and then on to the controversial Richard Owen, the era’s best-known scientist, and the one who coined the term “dinosaur.” “Exuberant” ( Kirkus Reviews ), entertaining, erudite, and featuring an unconventional cast of characters, Dinosaurs at the Dinner Party tells the story of how the accidental discovery of prehistoric creatures upended humanity’s understanding of the world and its own place within it.

Inspired by the wonder of his own parental experiences, former psychoanalyst and New York Times best-selling author Jeffrey Masson offers a remarkable look at one of the most fulfilling roles in the animal world: fatherhood. In The Evolution of Fatherhood , he explores the extraordinary dedication and behavior of nature's most outstanding dads. Discover the male emperor penguin incubating his egg through Antarctic blizzards, prairie dog dads teaching their pups vital life skills through play, and the South American tamarin monkey who actively "coaches" his mate through labor. Learn why wolves make devoted fathers, while their close relatives, dogs, often don't display the same level of paternal care. With captivating writing and impeccable research, Masson celebrates the unique and often surprising role males play in the lives of their young. He contrasts these heroes with nature's less involved fathers--like lions, langurs, and bears--and challenges the notion that paternal care is purely biological. Masson passionately demonstrates that for many animals, fatherhood is a profound, all-encompassing emotional experience. Compelling and inspirational, The Evolution of Fatherhood is a book that will forever change how you perceive parenthood, family bonds, and the rich emotional lives of the animals who share our world.

'In many ways it s the ultimate question in natural science: How does our universe work? Is there a fundamental theory? An incredible amount has been figured out about physics over the past few hundred years. But even with everything that s been done and it's very impressive - we still, after all this time, don t have a truly fundamental theory of physics.' The Wolfram Physics Project is a bold effort to find the fundamental theory of physics. It combines new ideas with the latest research in physics, mathematics and computation in the push to achieve this ultimate goal of science. Written with Stephen Wolfram's characteristic expository flair, this book provides a unique opportunity to learn about a historic initiative in science right as it is happening. A Project to Find the Fundamental Theory of Physics includes: The announcement of the project; A technical introduction; A history section that outlines the backstory which led Wolfram to this point; Background information from computational essays published by the author in 2015 and 2017; Foundational information, including historical notes and an excerpt from Wolfram's; 2002 New York Times Best Seller A New Kind of Science; Hundreds of beautiful full-colour visualisations. Stephen Wolfram is a distinguished scientist and best-selling author, and the creator of some of the world's most respected software systems, including Mathematica, Wolfram|Alpha and Wolfram Language. For more than 30 years he has been the CEO of the global technology company Wolfram Research.

This book first covers exact and approximate analytical techniques (ordinary differential and difference equations, partial differential equations, variational principles, stochastic processes); numerical methods (finite differences for ODE's and PDE's, finite elements, cellular automata); model inference based on observations (function fitting, data transforms, network architectures, search techniques, density estimation); as well as the special role of time in modeling (filtering and state estimation, hidden Markov processes, linear and nonlinear time series). Each of the topics in the book would be the worthy subject of a dedicated text, but only by presenting the material in this way is it possible to make so much material accessible to so many people. Each chapter presents a concise summary of the core results in an area, providing an orientation to what they can (and cannot) do, enough background to use them to solve typical problems, and pointers to access the literature for particular applications.

"A landmark collection of Pulitzer Prize winner Elizabeth Kolbert's most important pieces about climate change and the natural world "To be a well-informed citizen of Planet Earth," Rolling Stone has advised, "you need to read Elizabeth Kolbert." From her National Magazine Award-winning series The Climate of Man to her Pulitzer Prize-winning book The Sixth Extinction, Kolbert's work has shaped the way we think about the environment in the twenty-first century. Collected in Life on a Little-Known Planet are her most influential and thought-provoking essays. An intrepid reporter and a skillful translator of scientific idees, Kolbert expertly captures the wonders of nature and paints vivid portraits of the researchers and concerned citizens working to preserve them. She takes readers all around the globe, from an island in Denmark that's succeeded in going carbon neutral, to a community in Florida that voted to give rights to waterways, to the Greenland ice sheet, which is melting in a way that has implications for everyone. We meet a biologist who believes we can talk to whales, an entomologist racing to find rare caterpillars before they disappear, and a climatologist who's considered the "father of global warming," amongst other scientists at the forefront of environmental protection. The threats to our planet that Kolbert has devoted so much of her career to exposing have only grown more serious. Now is the time to deepen our understanding of the world we are in danger of losing"-- Provided by publisher.

The editors of this unique volume have selected 24 leading emotion theorists and asked them to address 12 fundamental questions about the subject of emotion. For example; Are there basic emotions? How do you distinguish emotions from moods, temperament, and emotional traits? Can we control our emotions? Can emotions be non-conscious? What is the relation between emotion and memory? What develops in emotional development? Each chapter addresses a different one of these fundamental questions about emotion, with often divergent answers from 3 to 7 of the following leading researchers: James Averill, Gordon Bower, Linda Camras, Lee Clark, Gerald Clore, Richard Davidson, Judy Dunn, Paul Ekman, Phoebe Ellsworth, Nico Frijda, Hill Goldsmith, Jeffrey Gray, Carroll Izard, Jerome Kaga, Richard Lazarus, Joseph Le Doux, Robert Levenson, Jaak Panksepp, Mary Rothbart, Klaus Shere, Richard Shweder, David Watson, and Robert Zajonc. At the end of each chapter the editors -- Ekman and Davidson -- highlight the areas of agreement and disagreement about each of the 12 questions about emotion. In the final chapter Affective Science: A Research Agenda, the editors describe the research they believe would help answer each of the questions. Not a textbook offering a single viewpoint, The Nature of Emotion, uniquely reveals the central issues in emotion research and theory in the words of many of the leading scientists working in the field today. It is ideal for students, researchers, and clinicians interested in emotion.

The beginning of the 21st century is a watershed in modern science, a time that will forever change our understanding of the universe, Susskind contends. Several decades ago, he introduced the revolutionary concept of string theory to the world of physical science. In doing so, he inspired a generation of physicists who believed that the theory would uniquely predict the properties of our universe. Now, in his first book, Susskind argues that the very idea of such an "elegant theory" no longer suits our understanding of the universe, and that our narrow 20th-century view of a unique universe will have to give way to the much broader concept of a gigantic cosmic landscape--a megaverse, pregnant with new possibilities.--[Résumé de l'éditeur].
