According to a recent survey, the most popular question about science from the general public was: what came before the Big Bang? We all know on some level what the Big Bang is, but we don't know how it became the accepted theory, or how we might know what came before. In Before the Big Bang , Brian Clegg (the critically acclaimed author of Upgrade Me and The God Effect ) explores the history of this remarkable concept. From the earliest creation myths, through Hershel's realization that the Milky Way was one of many galaxies, to on-going debates about Black Holes, this is an incredible look at the origins of the universe and the many theories that led to the acceptance of the Big Bang. But in classic scientist fashion Clegg challenges the notion of the "Big Bang" itself, and raises the deep philosophical question of why we might want to rethink the origin of the universe. This is popular science at its best, exploratory, controversial, and utterly engrossing. |

Ce hashtag unit les colères des maires et des citoyens méprisés. Depuis le 1er janvier 2025, si votre véhicule est trop ancien, il vous est impossible de circuler dans les " zones à faibles émissions " des grandes agglomérations. Et tant pis si vous n'avez pas les moyens de changer de voiture ! Mais quand 40 % de la population vit en milieu rural, ce sont plus de 20 millions de Français qui sont bannis des villes. Traités comme des #gueux, on dit NON à cette rupture d'égalité qui nous écrase. Ce hashtag unit les colères des maires et des citoyens méprisés. Jamais la ségrégation sociale n'est allée aussi loin. Et si les #gueux devenaient la voie de la reconnexion ? Une vague non partisane et républicaine, pour une écologie non violente et un retour à l'humanisme. |

This is a chemistry book like no other. This is your virtual consultant. If you work in any chemical company, our aim is to make this your survival guide. This is your portable consultant, available 24/7, and offering advice that cannot be obtained by cursory use of search engines. This consultant doesn't charge an hourly rate, has no ego, and is being constantly updated and improved upon. At no additional cost. In Part 1, The Portable Chemist's Consultant places particular emphasis on heterocyclic chemistry since this is the bedrock of society-shaping materials such as medicines and agrochemicals. Beautiful interactive graphics are designed to rapidly solve your problems by being both immersive and rapidly absorbed. In Part 2, a broad coverage of solutions to the most encountered problems and issues of industrial chemists is presented. We call it "speed consulting" - an amalgamation of dozens of commonly encountered problems and their best current solution. Finally, it features an extensive appendix with interesting topics for more advanced or specialized readers. All of the content is searchable with a built-in search engine. As alluded to above, The Portable Chemist's Consultant contains information that cannot easily be gleaned from online search engines and features objective advice to help navigate the ocean of data facing today's chemist. Our inspiration comes directly from the popular magazine Consumer Reports, run by a non-biased and non-profit organization to provide useful advice to consumers. In a similar vein, this book aims to save practicing chemists time, money, and frustration with simple advice often given in a rapidly absorbed graphical format. Advice is given with one sole criterion in mind: What would we do when faced with a similar problem? It is based on an extensive study of the literature, hands-on experience, and feedback from a decade of consulting in several sectors of industry such as pharmaceutical development, radiochemistry, medicinal chemistry, and agrochemistry. At the same time, this is an educational textbook based, in part, on a class in Heterocyclic Chemistry taught at the Scripps Research Institute for several years. Embedded videos from this class can be found throughout. This book was carefully created exclusively for the iPad featuring interactive figures, videos, and extensive hyperlinks to the literature. It will be suitable for both seasoned practitioners and newcomers alike. Best of all, it will be continually updated with new multimedia content, additional chapters, and tips even Google will not find. This book was designed with the reader in mind, and therefore comments, feedback, and suggestions for future updates to the book are most welcome.

A classic since 1928, this masterly encyclopedia of ancient mythology, ritual, symbolism, and the arcane mysteries of the ages is available for the first time in a compact "reader's edition." Like no other book of the twentieth century, Manly P. Hall's legendary The Secret Teachings of All Ages is a codex to the ancient occult and esoteric traditions of the world. Students of hidden wisdom, ancient symbols, and arcane practices treasure Hall's magnum opus above all other works. While many thousands of copies have sold since its initial publication in 1928, The Secret Teachings of All Ages has previously been available only in oversized, expensive editions. For the first time, Hall's celebrated classic is now published in an affordable trade paperback volume. Literally hundreds of entries shine a rare light on some of the most fascinating and closely held aspects of myth, religion, and philosophy from throughout the centuries. More than one hundred line drawings and a sixteen-page color insert reproduce some of the finest illustrations of the original book, while reset and reformatted text makes this edition of The Secret Teachings of All Ages newly accessible to readers everywhere. |

Rooted in neuroscience, psychology and evolutionary biology, this study explores what happens when we stop paying attention and the effect on our behavior. If we’ve done our job well—and, let’s be honest, if we’re lucky—you’ll read to the end of this description. Most likely, however, you won’t. Somewhere in the middle of the next paragraph, your mind will wander off. Minds wander. That’s just how it is. That may be bad news for me, but is it bad news for people in general? Does the fact that as much as fifty percent of our waking hours find us failing to focus on the task at hand represent a problem? Michael Corballis doesn’t think so. With The Wandering Mind , he shows us why, rehabilitating woolgathering and revealing its incredibly useful effects. Drawing on the latest research from cognitive science and evolutionary biology, Corballis shows us how mind-wandering not only frees us from moment-to-moment drudgery, but also from the limitations of our immediate selves. Mind-wandering strengthens our imagination, fueling the flights of invention, storytelling, and empathy that underlie our shared humanity; furthermore, he explains, our tendency to wander back and forth through the timeline of our lives is fundamental to our very sense of ourselves as coherent, continuing personalities. Full of unusual examples and surprising discoveries, The Wandering Mind mounts a vigorous defense of inattention—even as it never fails to hold the reader’s. Praise for The Wandering Mind “[A] conversational, sincere and amusing book about the tendency of our minds to stray from whatever it is we are actually supposed to be focusing on. . . . [An] engaging exploration of the subject.” — Times Higher Education , Book of the Week “Michael Corballis, the scientist, takes you by the hand and weaves through an avalanche of information from psychology, literature, history, and more to elucidate my favorite mental state—mind wandering. His high capacity for erudition, lucidity, and warmth have never shined more brightly.” —Michael S. Gazzaniga “ The Wandering Mind is a pleasure to read—a lively book that will appeal to a broad spectrum of readers.” —Thomas Suddendorf, author of The Gap |

An inspiring true-life survival story set in the remote backcountry of the Canadian Rockies. In August 2017, 32-year-old Jeremy Evans endured multiple ferocious attacks by a protective female grizzly bear while hunting in the Alberta wilderness. Jeremy’s injuries were massive, his scalp and face destroyed, an eye and his jaw dangling down. The tendons on one leg had been fully severed during the mauling. His hands were damaged where he had physically fought the bear. It was more than a dozen kilometres to where he had parked his truck in darkness early that morning and absolutely no one was near. Thoughts of his wife and their eight-month-old daughter consumed Jeremy as he stumbled and crawled for hours back to his truck, before driving himself several kilometres to a backcountry lodge for help. All the while, Jeremy thought of his young family and the upcoming sixth wedding anniversary that he feared he might never be able to celebrate. Mauled carefully details what happened deep in an Alberta forest where few modern humans tread. Jeremy’s miraculous recovery and life lessons learned when so close to death show that human determination can defy the greatest of odds, and that setting small goals along the road to recovery can lead to remarkable achievements. Despite the traumatic stress the encounter produced, Jeremy holds no animosity toward the bear and still enjoys spending time in the backcountry. To him the grizzly was doing what the best parents do: protect their young. |
