It enabled us to migrate out of Africa and to spread as far as Alaska and Australia. Every day, we put one foot in front of the other―yet how many of us know how we do that, or appreciate the advantages it gives us?Neuroscientist Shane O’Mara invites us to marvel at the benefits walking confers on our bodies and brains. From walking’s evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting- edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our “inner GPS” system. Walking, in turn, spurs our imaginations and boosts our moods. In Praise of Walking illuminates the joys, health benefits, and mechanics of walking―and reminds us to get out of our chairs and discover a happier, healthier, more creative self.

    Subjects ranging from the philosophical to the practical--what mathematics is and why it's worth doing, the relationship between logic and proof, the role of beauty in mathematical thinking, the future of mathematics, how to deal with the peculiarities of the mathematical community, and many others--are dealt with in Stewart's much-admired style, which combines subtle, easygoing humor with a talent for cutting to the heart of the matter. In the tradition of G.H. Hardy's classic A Mathematician's Apology, this book is sure to be a perennial favorite with students at all levels, as well as with other readers who are curious about the frequently incomprehensible world of mathematics.

    Pulitzer Prize–winning author Siddhartha Mukherjee, a leading cancer physician and researcher, selects the year’s top science and nature writing from journalists who dive into their fields with curiosity and passion, delivering must-read articles from a wide array of fields.

    This entertaining examination of everyday science from the fanciful to the factual covers topics ranging from pesticides and environmental estrogens to lipsticks and garlic.

    This remarkable book reflects his simple and powerful message as well as the quiet, joyful Buddhist practice of dhudanga, or "everyday mindfulness," with profound insights for the West.

    

    Beginning at the time of Alexander the Great, the monsters come fast and furious--Behemoth and Leviathan, Gog and Magog, Satan and his demons, Grendel and Frankenstein, circus freaks and headless children, right up to the serial killers and terrorists of today and the post-human cyborgs oftomorrow. Monsters embody our deepest anxieties and vulnerabilities, Asma argues, but they also symbolize the mysterious and incoherent territory beyond the safe enclosures of rational thought. Exploring sources as diverse as philosophical treatises, scientific notebooks, and novels, Asma unravelstraditional monster stories for the clues they offer about the inner logic of an era's fears and fascinations. In doing so, he illuminates the many ways monsters have become repositories for those human qualities that must be repudiated, externalized, and defeated.

    This brief introduction shows how psycholinguistic research can act as a window to the workings of the human mind and the study of consciousness.

    The author shows that no matter how bizarre a people's behavior may seem, it always stems from concrete social and economic conditions. It is by isolating and identifying these conditions that we will be able to understand and cope with some of our own apparently senseless life styles. In a devastating attack on the shamans of the counterculture, the author states the case for a return to objective consciousness and a rational set of political commitments.

    The first half of the book deals with classical physical optics; the second principally with the quantum nature of light. Chapters 1 and 2 treat the propagation of light waves, including the concepts of phase and group velocities, and the vectorial nature of light. Chapter 3 applies the concepts of partial coherence and coherence length to the study of interference, and Chapter 4 takes up multiple-beam interference and includes Fabry-Perot interferometry and multilayer-film theory. Diffraction and holography are the subjects of Chapter 5, and the propagation of light in material media (including crystal and nonlinear optics) are central to Chapter 6. Chapters 7 and 8 introduce the quantum theory of light and elementary optical spectra, and Chapter 9 explores the theory of light amplification and lasers. Chapter 10 briefly outlines ray optics in order to introduce students to the matrix method for treating optical systems and to apply the ray matrix to the study of laser resonators.Many applications of the laser to the study of optics are integrated throughout the text. The author assumes students have had an intermediate course in electricity and magnetism and some advanced mathematics beyond calculus. For classroom use, a list of problems is included at the end of each chapter, with selected answers at the end of the book.

    Ten dimensions? Most of us have barely gotten used to the idea that there are four.Using simple geometry and an easygoing writing style, author Rob Bryanton starts with the lower dimensions that we are all familiar with, then uses those concepts to build one layer upon another, ultimately arriving at a way of imagining the tenth dimension.Part scientific exploration, part philosophy, this unique book touches upon such diverse topics as dark matter, Feynman's "sum over paths", the quantum observer, and the soul. It is aimed at anyone interested in leading-edge theories about cosmology and the nature of reality, but it is not about mainstream physics. Rather, Imagining the Tenth Dimension is a mind-expanding exercise that could change the way you view this incredible universe in which we live.

    Dehaene's research will fascinate not only readers interested in science and culture, but also educators concerned with debates on how we learn to read, and who wrestle with pathologies such as dyslexia. Like Steven Pinker, Dehaene argues that the mind is not a blank slate: Writing systems across all cultures rely on the same brain circuits, and reading is only possible insofar as it fits within the limits of a primate brain. Setting cutting-edge science in the context of cultural debate, Reading in the Brain is an unparalleled guide to a uniquely human ability.

    Covering Sid's early years in South Africa and life as a ladies' hairdresser, his obsession with gambling and women, his questioning by Scotland Yard in a murder case, Hancock's Half Hour and the Carry On films, and Sid's death on stage at the age of 63, Cliff Goodwin reveals the amazing truth behing the legend.

    Witty, thoughtful, and practical, this is a thinking person's guide to the how--and why--of watching what you eat."I urge you to live at the peak of enjoyment of life," Richard Watson writes. "Descartes said that the essence of the soul is self-consciousness. If you want to enjoy your life, pay attention to what you are doing. Control as much of your life as you can. Live in full consciousness. And don't stop thinking for yourself."Here's an erudite and fascinating combination of common sense, Cartesian philosophy, and the presumption that understanding the mysteries of weight loss and the universe are somehow compatible, even sympathetic, ambitions. If Descartes had written a treatise on losing weight as a way to maintain discipline amidst life's vicissitudes, it would have read much like this. Richard Watson wants you to lose weight, as he did, while gaining new wisdom about yourself--and what you eat.

    Einstein said that the most incredible thing about our universe was that it was comprehensible at all. As Kitty Ferguson explains, Pythagoras had much the same idea - but 2,500 years earlier. Though known by many only for his famous Theorem, in fact the pillars of our scientific tradition - belief that the universe is rational, that there is unity to all things, and that numbers and mathematics are a powerful guide to truth about nature and the cosmos - hark back to the convictions of this legendary scholar. Kitty Ferguson brilliantly evokes Pythagoras' ancient world of, showing how ideas spread in antiquity, and chronicles the incredible influence he and his followers have had on so many extraordinary people in the history of Western thought and science. 'Pythagoras' influence on the ideas, and therefore on the destiny, of the human race was probably greater than that of any single man before or after him' - Arthur Koestler.
