Full of insights, arguments and philosophical perspectives, the book covers an amazing array of topics. Beginning in antiquity with Democritus, it progresses through logic and set theory, computability and complexity theory, quantum computing, cryptography, the information content of quantum states and the interpretation of quantum mechanics. There are also extended discussions about time travel, Newcomb's Paradox, the anthropic principle and the views of Roger Penrose. Aaronson's informal style makes this fascinating book accessible to readers with scientific backgrounds, as well as students and researchers working in physics, computer science, mathematics and philosophy.

    It was studied from antiquity to the Renaissance as a way of glimpsing the nature of reality. Geometry is number in space; music is number in time; and comology expresses number in space and time. Number, music, and geometry are metaphysical truths: life across the universe investigates them; they foreshadow the physical sciences.Quadrivium is the first volume to bring together these four subjects in many hundreds of years. Composed of six successful titles in the Wooden Books series-Sacred Geometry, Sacred Number, Harmonograph, The Elements of Music, Platonic & Archimedean Solids, and A Little Book of Coincidence-it makes ancient wisdom and its astonishing interconnectedness accessible to us today.Beautifully produced in six different colors of ink, Quadrivium will appeal to anyone interested in mathematics, music, astronomy, and how the universe works.

    Authors Peter Tompkins and Christopher Bird suggest that the most far-reaching revolution of the 20th century — one that could save or destroy the planet — may come from the bottom of your garden."Almost incredible ... bristles with plenty of hard facts and astounding scientific and practical lore." —S. K. Oberbeck, Newsweek“This fascinating book roams ... over that marvelous no man's land of mystical glimmerings into the nature of science and life itself." —Henry Mitchell, Washington Post Book World“If I can't ‘get inside a plant’ or ‘feel emanations’ from a plant and don't know anyone else who can. that doesn't detract one whit from the possibility that some people can and do. . . .According to The Secret Life of Plants, plants and men do inter-relate, with plants exhibiting empathetic and spiritual relationships and showing reactions interpreted as demonstrating physical-force connections with men. As my students say, ‘hey, wow!’"—Richard M. Klein, Professor of Botany, University of Vermont (in Smithsonian)

    He reveals what is real and what is illusory, in the process exposing moves that can harm or even kill. Five years in the making, The Science of Yoga draws on a hidden wealth of discovery, drama, and surprising fact to cut through the fog that surrounds contemporary yoga and to show—for the first time—what is uplifting and beneficial and what is delusional, flaky, and dangerous. At heart, it illuminates the risks and rewards.Broad describes yoga as a burgeoning global industry that attracts not only curious scientists but millions of true believers and charismatic hustlers. He takes the reader on a whirlwind tour of unknown yoga that goes from old archives in Calcutta to world capitals of medical research, from storied ashrams to spotless laboratories, from sweaty yoga studios with master teachers to the cozy offices of yoga healers. In the process, he shatters myths, lays out unexpected benefits, and offers a compelling vision of how the discipline can be improved.

    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.

    In this rich work, Robert Johnson guides us through an exploration of the shadow: what it is, how it originates, and how it interacts and is made through the process of acculturation.Johnson asserts that until we have undertaken the task of accepting and honoring the shadow within us, we cannot be balanced or whole, for what is hidden never goes away, but merely—and often painfully—turns up in unexpected places.

    

    From the esoteric account of the evolution of the species to the occult roots of science, from the secrets of the Flood to the esoteric motives behind American foreign policy, here is a narrative history that shows the basic facts of human existence on this planet can be viewed from a very different angle. Everything in this history is upside down, inside out and the other way around.At the heart of "The Secret History of the World" is the belief that we can reach an altered state of consciousness in which we can see things about the way the world works that are hidden from us in our everyday, commonsensical consciousness. This history shows that by using secret techniques, people such as Leonardo da Vinci, Isaac Newton and George Washington have worked themselves into this altered state - and been able to access supernatural levels of intelligence. There have been many books on the subject, but, extraordinarily, no-one has really listened to what the secret societies themselves say. The author has been helped in his researches by his friendship with a man who is an initiate of more than one secret society, and in one case an initiate of the highest level.

    Clear and friendly, this in-depth practice manual builds on the nine-stage model of meditation originally articulated by the ancient Indian sage Asanga, crystallizing the entire meditative journey into 10 clearly-defined stages. The book also introduces a new and fascinating model of how the mind works, and uses illustrations and charts to help the reader work through each stage. This manual is an essential read for the beginner to the seasoned veteran of meditation and can be read from front to back, or used as a reference guide, choosing chapters as needed based on the current state of the reader’s practice.

    In ancient times, the warrior learned to master the challenges of life, both on and off the battlefield. He acquired a sense of personal freedom and power—not through violence or aggression, but through gentleness, courage, and self-knowledge. The Japanese samurai, the warrior-kings of Tibet, the knights of medieval Europe, and the warriors of the Native American tribes are a few examples of this universal tradition of wisdom. With this book the warrior's path is opened to contemporary men and women in search of self-mastery and greater fulfillment. Interpreting the warrior's journey in modern terms, Trungpa discusses such skills as synchronizing mind and body, overcoming habitual behaviors, relaxing within discipline, facing the world with openness and fearlessness, and finding the sacred dimension of everyday life. Above all, Trungpa shows that in discovering the basic goodness or human life, the warrior learns to radiate that goodness out into the world for the peace and sanity of others. The Shambhala teachings—named for a legendary Himalayan kingdom where prosperity and happiness reign—thus point to the potential for enlightened conduct that exists within every human being. "The basic wisdom of Shambhala," Trungpa writes, "is that in this world, as it is, we can find a good and meaningful human life that will also serve others. That is our true richness."

    Suicides, accidental, and natural deaths can occur without any evidence from outside the room. But murders typically involve suspects external to the crime scene. If there’s evidence of an outside intruder, homicide detectives have to prepare for a chase. Intruders turn death scenes into crime scenes. Join J. Warner Wallace, former atheist, seasoned cold-case detective, and popular national speaker as he tackles his most important case ... with you on the jury! With the expertise of a cold-case detective, J. Warner examines eight critical pieces of evidence in the “crime scene” of the universe to determine if they point to a Divine Intruder. If you have ever wondered if something (or someone) outside the natural realm created the universe and everything in it, this is the case for you.

      What do you do when God dies? It's a question facing millions today, as science reveals a Universe that's self-creating, as American culture departs from Christian social norms, and the idea of God begins to seem implausible at best and barbaric at worst.   Mike McHargue understands the pain of unraveling belief. In Finding God in the Waves, Mike tells the story of how his Evangelical faith dissolved into atheism as he studied the Bible, a crisis that threatened his life, his friendships, and even his marriage. Years later, Mike was standing on the shores of the Pacific Ocean when a bewildering, seemingly mystical moment motivated him to take another look. But this time, it wasn't theology or scripture that led him back to God—it was science.    In Finding God in the Waves, "Science Mike” draws on his personal experience to tell the unlikely story of how science led him back to faith. Among other revelations, we learn what brain scans reveal about what happens when we pray; how fundamentalism affects the psyche; and how God is revealed not only in scripture, but in the night sky, in subatomic particles, and in us.   For the faithful and skeptic alike, Finding God in the Waves is a winsome, lucid, page-turning read about belonging, life’s biggest questions, and the hope of knowing God in an age of science.

    Much more commonly, they are linked to sensory deprivation, intoxication, illness, or injury. People with migraines may see shimmering arcs of light or tiny, Lilliputian figures of animals and people. People with failing eyesight, paradoxically, may become immersed in a hallucinatory visual world. Hallucinations can be brought on by a simple fever or even the act of waking or falling asleep, when people have visions ranging from luminous blobs of color to beautifully detailed faces or terrifying ogres. Those who are bereaved may receive comforting “visits” from the departed. In some conditions, hallucinations can lead to religious epiphanies or even the feeling of leaving one’s own body. Humans have always sought such life-changing visions, and for thousands of years have used hallucinogenic compounds to achieve them. As a young doctor in California in the 1960s, Oliver Sacks had both a personal and a professional interest in psychedelics. These, along with his early migraine experiences, launched a lifelong investigation into the varieties of hallucinatory experience. Here, with his usual elegance, curiosity, and compassion, Dr. Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organization and structure of our brains, how they have influenced every culture’s folklore and art, and why the potential for hallucination is present in us all, a vital part of the human condition.

    Based on a course in Paganism that the authors have taught for more than a decade, it is full of exercises, meditations, and discussion questions for group or individual study.This book presents the basic fundamentals of Paganism. It explores what Pagans are like; how the Pagan sacred year is arranged; what Pagans do in ritual; what magick is; and what Pagans believe about God, worship, human nature, and ethics.For those who are exploring their own spirituality, or who want a good book to give to non-Pagan family and friends A hands-on learning tool with magickal workings, meditations, discussion questions, and journal exercises Offers in-depth discussion of ethics and magick

    The authors also make an important contribution to the interpretation of The Tibetan Book of the Dead. They show that it is concerned not with the dead, but with the living. The last section of the manual provides instructions for an actual psychedelic session, under adequate safeguards.The authors were engaged in a program of experiments with LSD and other psychedelic drugs at Harvard University until sensational national publicity unfairly concentrating on student interest in the drugs, led to the suspension of the experiments. Since then, the authors have continued their work without academic auspices.
