A “rock star” (New York Times) of the computing world provides a radical new work on the meaning of human consciousness. The holy grail of psychologists and scientists for nearly a century has been to understand and replicate both human thought and the human mind. In fact, it's what attracted the now-legendary computer scientist and AI authority David Gelernter to the discipline in the first place. 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.

In Tides: The Science and Spirit of the Ocean, writer, sailor, and surfer Jonathan White takes readers across the globe to discover the science and spirit of ocean tides. In the Arctic, White shimmies under the ice with an Inuit elder to hunt for mussels in the dark cavities left behind at low tide; in China, he races the Silver Dragon, a twenty-five-foot tidal bore that crashes eighty miles up the Qiantang River; in France, he interviews the monks that live in the tide-wrapped monastery of Mont Saint-Michel; in Chile and Scotland, he investigates the growth of tidal power generation; and in Panama and Venice, he delves into how the threat of sea level rise is changing human culture—the very old and very new. Tides combines lyrical prose, colorful adventure travel, and provocative scientific inquiry into the elemental, mysterious paradox that keeps our planet’s waters in constant motion. Photographs, scientific figures, line drawings, and sixteen color photos dramatically illustrate this engaging, expert tour of the tides.

After decades of internecine warfare, the tribes of the Tiste Edur have at last united under the Warlock King of the Hiroth. There is peace--but it has been exacted at a terrible price: a pact made with a hidden power whose motives are at best suspect, at worst, deadly. To the south, the expansionist kingdom of Lether, eager to fulfill its long-prophesized renaissance as an Empire reborn, has enslved all its less-civilized neighbors with rapacious hunger. All, that is, save one--the Tiste Edur. And it must be only a matter of time before they too fall--either beneath the suffocating weight of gold, or by slaughter at the edge of a sword. Or so destiny has decreed. Yet as the two sides gather for a pivotal treaty neither truly wants, ancient forces are awakening. For the impending struggle between these two peoples is but a pale reflection of a far more profound, primal battle--a confrontation with the still-raw wound of an old betrayal and the craving for revenge at its seething heart.

The book is a diary of a physician/father over 25 years of family life and his practice of medicine. The author kept a journal and although this journal reflects his mood and attitude at the time, it is a description about experiences, occurrences and important decisions. These transitions and tides are chronicled whether it be family life, building a practice, or operating a health system. The result is a journal that describes seemingly minor events that directed the author and his family in certain directions and as a result, this story. "Tides and Transitions" describes those people, events, and the stories that helped develop, mature, and challenge the family and medical practice. It is bits and pieces of the life of a young then middle aged physician and father.
