His work won him the Nobel Prize in 1922 and his ideas continue to propel physics towards new discoveries. But what is quantum theory? Most of us do not understand even the basics of one of the most significant scientific advances ever made, opening up a whole new field in science, whose ambiguities still challenge scientists around the world.Bohr and Quantum Theory offers an accessible and absorbing account of the man who was both a part of The Manhattan Project but also an advocate of peace.He held the key to understanding such intricate realities as black holes and nuclear energy. Bohr's Big Idea explains complex and crucial ideas in a clear and engaging way, placing quantum theory in the context of a man's life, work and time and examining its important implications for our future.The Big Idea series is a fascinating look at the greatest advances in our scientific history, and at the men and women who made these fundamental breakthroughs.

    Accordingly, he once derided as "spooky action at a distance" the notion that two elementary particles far removed from each other could nonetheless influence each other's properties—a hypothetical phenomenon his fellow theorist Erwin Schrödinger termed "quantum entanglement."In a series of ingenious experiments conducted in various locations—from a dank sewage tunnel under the Danube River to the balmy air between a pair of mountain peaks in the Canary Islands—the author and his colleagues have demonstrated the reality of such entanglement using photons, or light quanta, created by laser beams. In principle the lessons learned may be applicable in other areas, including the eventual development of quantum computers.

    Nor is it known whether religious believers and nonbelievers differ in how they evaluate statements of fact. Our lab previously has used functional neuroimaging to study belief as a general mode of cognition [1], and others have looked specifically at religious belief [2]. However, no research has compared these two states of mind directly.Methodology/Principal FindingsWe used functional magnetic resonance imaging (fMRI) to measure signal changes in the brains of thirty subjects—fifteen committed Christians and fifteen nonbelievers—as they evaluated the truth and falsity of religious and nonreligious propositions. For both groups, and in both categories of stimuli, belief (judgments of “true” vs judgments of “false”) was associated with greater signal in the ventromedial prefrontal cortex, an area important for self-representation [3], [4], [5], [6], emotional associations [7], reward [8], [9], [10], and goal-driven behavior [11]. This region showed greater signal whether subjects believed statements about God, the Virgin Birth, etc. or statements about ordinary facts. A comparison of both stimulus categories suggests that religious thinking is more associated with brain regions that govern emotion, self-representation, and cognitive conflict, while thinking about ordinary facts is more reliant upon memory retrieval networks.Conclusions/SignificanceWhile religious and nonreligious thinking differentially engage broad regions of the frontal, parietal, and medial temporal lobes, the difference between belief and disbelief appears to be content-independent. Our study compares religious thinking with ordinary cognition and, as such, constitutes a step toward developing a neuropsychology of religion. However, these findings may also further our understanding of how the brain accepts statements of all kinds to be valid descriptions of the world.Author ContributionsConceived and designed the experiments: Sam Harris, Jonas T.

    But even spending an entire day with Ozzy Osbourne wasn't as frightening as when he agreed to follow Philadelphia "demonologist" Lou Gentile on his appointed rounds. Will Storr never believed in ghosts—but his healthy skepticism couldn't explain the strange lights and sounds he witnessed, and the weird behavior of the occupants of several allegedly haunted houses.What resulted is a confirmed cynic's (and proud of it!) dedicated search for answers in a shadowy world of séances, mediums, devil worshippers—even the Vatican's chief exorcist. So get ready to confront the genuinely creepy along with the hilariously ridiculous in Will Storr vs. the Supernatural!

    In treating cognition as problem solving, Andy Clark suggests, we may often abstract too far from the very body and world in which our brains evolved to guide us. Whereas the mental has been treated as a realm that is distinct from the body and the world, Clark forcefully attests that a key to understanding brains is to see them as controllers of embodied activity. From this paradigm shift he advances the construction of a cognitive science of the embodied mind.

    His fascinating quest draws on the history of philosophy, but also anthropology, sociology, psychology and neurology; he talks to theologians, priests, allegedly reincarnated Lamas, and delves into real-life cases of lost memory, personality disorders and personal transformation; and, candidly and engagingly, he describes his own experiences. After reading "The Ego Trick," you will never see yourself in the same way again.

    Theories that contain time as a simple quantity form the basis of our understanding of many scientific disciplines, yet the debate rages on: why does there seem to be a direction to time, an arrow of time pointing from past to future?In The Arrow of Time, a major bestseller in England, Dr. Peter Coveney, a research scientist, and award-winning journalist Dr. Roger Highfield, demonstrate that the commonsense view of time agrees with the most advanced scientific theory. Time does in fact move like an arrow, shooting forward into what is genuinely unknown, leaving the past immutably behind. The authors make their case by exploring three centuries of science, offering bold reinterpretations of Newton's mechanics, Einstein's special and general theories of relativity, quantum mechanics, and advancing the insights of James Gleick's Chaos.

    This time physicist Robert Gilmore takes us on a journey with Dorothy, following the yellow building block road through the land of the Wizard of Quarks. Using characters and situations based on the Wizard of Oz story, we learn along the way about the fascinating world of particle physics. Classes of particles, from quarks to leptons are shown in an atomic garden, where atoms and molecules are produced. See how Dorothy, The Tin Geek, and the Cowardly Lion experience the bizarre world of subatomic particles.

    Schrödinger's world view, derived from the Indian writings of the Vedanta, is that there is only a single consciousness of which we are all different aspects. He admits that this view is mystical and metaphysical and incapable of logical deduction. But he also insists that this is true of the belief in an external world capable of influencing the mind and of being influenced by it. Schrödinger's world view leads naturally to a philosophy of reverence for life.

    . . . The main lines of argument—that the emotions are ways we constitute our lives with meaning; that they are in some important sense things we do rather than things that merely happen to us; that emotions have their own sort of rationality and logic and are subject to evaluation and criticism as such; that emotions are, in some important sense, evaluative judgments—remain an important, credible contemporary view. . . . Solomon is clear, clever, and deep (also often funny).” —Owen Flanagan, Duke University

    I’m Tim. I’m a single cell in society’s body. U.S. society, to be specific.So let me explain why we’re here.As a writer and a generally thinky person, I’ve spent a lot of my life thinking about the society I live in, and societies in general. I’ve always imagined society as a kind of giant human—a living organism like each of us, only much bigger.When you’re a single cell in the body of a giant, it’s hard to understand what the giant’s doing, or why it is the way it is, because you can’t really zoom out and look at the whole thing all at once. But we do our best.The thing is, when I’ve recently tried to imagine what society might look like, I haven’t really been picturing this:Giant stick figure: "I am grown up."Based on what I see around me, in person and online, it seems like my society is actually more like this:Giant stick figure throwing a giant tantrum because their chocolate ice cream fell on the ground.Individual humans grow older as they age—but it kind of seems like the giant human I live in has been getting more childish each year that goes by.So I decided to write a blog post about this. But then something else happened.When I told people I was planning to write a post about society, and the way people are acting, and the way the media is acting, and the way the government is acting, and the way everyone else is acting, people kept saying the same thing to me.Don’t do it. Don’t touch it. Write about something else. Anything else. It’s just not worth it.They were right. With so many non-controversial topics to write about, why take on something so loaded and risk alienating a ton of readers? I listened to people’s warnings, and I thought about moving on to something else, but then I was like, “Wait what? I live inside a giant and the giant is having a six-year-old meltdown in the grocery store candy section and that’s a not-okay thing for me to talk about?”It hit me that what I really needed to write about was that—about why it’s perilous to write about society."

    As a student and young researcher in the 1980s, Gelernter hoped to build a program with a dial marked "focus." At maximum "focus," the program would "think" rationally, formally, reasonably. As the dial was turned down and "focus" diminished, its "mind" would start to wander, and as you dialed even lower, this artificial mind would start to free-associate, eventually ignoring the user completely as it cruised off into the mental adventures we know as sleep.While the program was a only a partial success, it laid the foundation for The Tides of Mind, a groundbreaking new exploration of the human psyche that shows us how the very purpose of the mind changes throughout the day. Indeed, as Gelernter explains, when we are at our most alert, when reasoning and creating new memories is our main mental business, the mind is a computer-like machine that keeps emotion on a short leash and attention on our surroundings. As we gradually tire, however, and descend the "mental spectrum," reasoning comes unglued. Memory ranges more freely, the mind wanders, and daydreams grow more insistent. Self-awareness fades, reflection blinks out, and at last we are completely immersed in our own minds.With far-reaching implications, Gelernter’s landmark "Spectrum of Consciousness" finally helps decode some of the most mysterious wonders of the human mind, such as the numinous light of early childhood, why dreams are so often predictive, and why sadism and masochism underpin some of our greatest artistic achievements. It’s a theory that also challenges the very notion of the mind as a machine—and not through empirical studies or "hard science" but by listening to our great poets and novelists, who have proven themselves as humanity's most trusted guides to the subjective mind and inner self.In the great introspective tradition of Wilhelm Wundt and René Descartes, David Gelernter promises to not only revolutionize our understanding of what it means to be human but also to help answer many of our most fundamental questions about the origins of creativity, thought, and consciousness.

    To shape debates over health care, energy policy, space travel, and other vital issues, ordinary citizens must engage directly with research rather than relying on pundits’ and politicians’ interpretations. Otherwise, fringe opinions that have been discredited in the scientific community can take hold in the public imagination. At the same time, scientists must understand their roles as communicators and ambassadors as well as researchers.Rees not only diagnoses this central problem but also explains how scientists and the general public can deploy a global, long-term perspective to address the new challenges we face. In the process, he reveals critical shortcomings in our current system—for example, the tendency to be overly anxious about minor hazards while underrating the risk of potential catastrophes. Offering a strikingly clear portrait of the future of science, Rees tackles such diverse topics as the human brain, the possibility that humans will colonize other planets, and the existence of extraterrestrial life in order to distinguish between what scientists can hope to discover and what will always lie beyond our grasp.A fresh perspective on science’s significance and potential, From Here to Infinity will inspire and enlighten.

    But those that aren't, those that purport to document or comment on such phenomena in what passes for "real life" vary across such a wide range of quality, credulity & comprehensibility that it's tempting to dismiss them all as pure badly-written hokum. Of course, as in any genre, no matter how microscopic, there are classics. Charles Fort's Book of the Damned is surely in the forefront. But once you get past the looming shadow of Charles Fort, matters become far murkier. Patrick Harpur's Daimonic Reality is a work that would surely make the top ten lists of many Fortean scholars. Subtitled A Field Guide to the Otherworld, Daimonic Reality synthesizes the reports of many different phenomena into a single Unified Field Theory of the Strange. It's an audacious attempt that largely succeeds. Harpur has a low key writing style that makes this work easy to read. His comprehensive knowledge of a wide variety of inexplicable events is impressive & entertaining. Most importantly, he has drawn together these disparate elements with a rather interesting philosophical take that looks to Jung, Fort, Blake, Yeats & beyond. There are enough elements in this stew to make it a really tasty treat for the hungry mind. Daimonic Reality is divided into three sections thru which Harpur journeys ever deeper into the mind behind the perceptions. But he's careful not to shortchange the perceptions & events themselves. Part One: Apparitions covers apparitions of all kinds, from UFOs to lights in the sky, from aliens & fairies to sightings of Black Dogs & Big Cats. Harpur's economical coverage of these subjects makes it easy for any level of Fortean reader to enjoy the individuality of each experience. But this treatment also enables the reader to step back & see the bigger picture, to move towards the idea of the otherworld. The individual reports are carefully chosen & beautifully written. Harpur takes a more substantial step towards the otherworld in Part Two: Vision. Starting with a discussion of "seeing things", he moves on to visions of Ladies, which are dominated by (but not exclusively) visions of the Blessed Virgin Mary. He discusses the evidence that these encounters leave behind, from fairy shoes to crop circles. (Coming soon to a theater near you.) He talked about the part that Imagination plays in the otherworld & finally reaches the mythic land itself. In Part Three: Otherworld Journeys, Harpur gives both practical & philosophical advice for otherworld journeys. He discusses the variety of journeys that one can have, from missing time to alien encounters, from a trip to fairyland to an out-of-body experience. When Harpur sticks to the practical, he has practically no peer in writing compelling prose about otherworldly experiences. His philosophical thoughts aren't quite as page-turning, but they're pithy, fascinating & pertinent. Harpur isn't content to merely provoke thought. He wants to invoke internal debate in the reader, & does so with some formal philosophical discussion that is difficult to pull off with the authority that Harpur achieves. He's a remarkably intelligent writer & his work requires a reader of nearly equal intelligence. You don't have to be a philosopher to read Harpur's work, but it certainly helps to be philosophically inclined. This isn't mere reportage of events, but a reasoned analysis, with conclusions that go well beyond 'Is it real or are they all just a bunch of crazy yahoos?' That there is an audience for this sort of thinking is shown by the eternal sales of the works of writers such as Carlos Castenada, not to mention the immense & increasing popularity of Fortean fiction, horror, science fiction & fantasy. That's because Harpur is looking to snatch something from the center of creation, something that is partly in the human mind & partly in the otherworld. Daimonic Reality does an excellent job grasping at the ineffable & getting it in print. As of 2/2003, this title is back in print by Pine Winds Press/Idyll Arbor. They've chosen an equally nice cover print, & are publishing the book as a sturdy US hardcover. Better yet, they're a small press, so you can buy directly from them. Since Harpur has managed to wrestle the ineffable into print, we've got to thank Pine Winds Press for keeping it in print.--Rick Kleffel
