    Written for both the casual reader and the science buff hungry for new information, The Vision Revolution is a resource that dispels commonly believed perceptions about sight and offers answers drawn from the field’s most recent research.Changizi focuses on four “why” questions:1. Why do we see in color?2. Why do our eyes face forward?3. Why do we see illusions?4. Why does reading come so naturally to us?Why Do We See in Color?It was commonly believed that color vision evolved to help our primitive ancestors identify ripe fruit. Changizi says we should look closer to home: ourselves. Human color vision evolved to give us greater insights into the mental states and health of other people. People who can see color changes in skin have an advantage over their color-blind counterparts; they can see when people are blushing with embarrassment, purple-faced with exertion or the reddening of rashes. Changizi’s research reveals that the cones in our eyes that allow us to see color are exquisitely designed exactly for seeing color changes in the skin. And it’s no coincidence that the primates with color vision are the ones with bare spots on their faces and other body parts; Changizi shows that the development of color vision in higher primates closely parallels the loss of facial hair, culminating in the near hairlessness and highly developed color vision of humans.Why Do Our Eyes Face Forward?Forward-facing eyes set us apart from most mammals, and there is much dispute as to why we have them. While some speculate that we evolved this feature to give us depth perception available through stereo vision, this type of vision only allows us to see short distances, and we already have other mechanisms that help us to estimate distance. Changizi’s research shows that with two forward-facing eyes, primates and humans have an x-ray ability. Specifically, we’re able to see through the cluttered leaves of the forest environment in which we evolved. This feature helps primates see their targets in a crowded, encroached environment. To see how this works, hold a finger in front of your eyes. You’ll find that you’re able to look “through” it, at what is beyond your finger. One of the most amazing feats of two forward-facing eyes? Our views aren’t blocked by our noses, beaks, etc.Why Do We See Illusions?We evolved to see moving objects, not where they are, but where they are going to be. Without this ability, we couldn’t catch a ball because the brain’s ability to process visual information isn’t fast enough to allow us to put our hands in the right place to intersect for a rapidly approaching baseball. “If our brains simply created a perception of the way the world was at the time light hit the eye, then by the time that perception was elicited—which takes about a tenth of a second for the brain to do—time would have marched on, and the perception would be of the recent past,” Changizi explains. Simply put, illusions occur when our brain is tricked into thinking that a stationary two-dimensional picture has an element that is moving. Our brains project the “moving” element into the future and, as a result, we don’t see what’s on the page, but what our brain thinks will be the case a fraction of a second into the future.Why Does Reading Come So Naturally to Us?We can read faster than we can hear, which is odd, considering that reading is relatively recent, and we’ve evolved to process speech for millions of years. Changizi’s research reveals that language has been carefully designed to tap in to elements of the visual processing center that have evolved for tens of millions of years. Visual signs of all languages are shaped like objects in nature, Changizi says, because we have evolved to see nature easily. “People have noticed letters in nature for some time, and there are artists who have a spent a lot of time photographing Latin letters in natural scenes or on butterfly wings,” Changizi says. “For example, if you look at an upper corner of the room you are in, you will see three contours meeting at a point, making a shape close to that of a ‘Y.’“ The Vision Revolution expands upon how our ancestors found the shapes of Latin letters and delves into how visual signs can have similar shapes even though their inspirations come from very different environments.In addition to these four areas, The Vision Revolution explores other phenomena such as cyclopses, peeking and many more you hadn’t even thought to wonder about. Changizi shows how deeply involved these evolutionary aspects of our vision are in why we see the way we do—and what the future holds for us.“…to understand how culture interacts with vision, one must understand not just the eye’s design, but the actual mechanisms we have evolved,” Changizi says, “for culture can tap in to both the designed responses of our brains and the unintended responses.”The Vision Revolution is a book that finally gives attention to what before has been largely neglected by other works on human vision—a book that looks at the “why.”

    Indeed, starting from this tiny, common speck, Jan Zalasiewicz offers readers a stimulating tour that begins with the Universe's dramatic birth in the unimaginable violence of the Big Bang and explores the construction of the Solar System and the origins of our own planet. Zalasiewicz shows the almost incredible complexity present in the apparently mundane pebble, starting with the astonishing number of atoms in each. We learn that many events in the Earth's ancient past can be deciphered from a pebble: volcanic eruptions; the lives and deaths of extinct animals and plants; the alien nature of long-vanished oceans; and even the creations of fool's gold and oil deep underground. Zalasiewicz also demonstrates how geologists reach deep into the Earth's past by forensic analysis of even the tiniest amounts of mineral matter. The pebble may be small, and ordinary, but it is also an eloquent part of our Earth's extraordinary, never-ending story.

    The world you live in is stranger than fiction... as you read this, you exist in other places at the same time. Do not regret having missed the chance to realize your dreams, for you may just have fulfilled it in another universe.. * Are the trillions of atoms that make you, nothing but vibrations in 10 dimensions?* Is it true that we are all connected with each other?* Can you go into the future to change the present?* Why do scientists and philosophers struggle with the concept of Time?* Can science explain consciousness through physics?* Is our fate driven by the underlying randomness in nature?* Is nature hiding the best-kept secrets which can never be unravelled by humans?The Speed of Time approaches the most complex and esoteric theories of science in lucid, clear and simple language and in the style of a thriller, leaving you wanting more... while addressing questions through the enigmatic theories in Physics such as Quantum Mechanics, Einstein's Theory of Relativity, Time, Chaos, and much more. Just start reading and you will not put it down.

    Every day, we break our fast. Hunger explores the range of this primal experience. Sharman Apt Russell, the highly acclaimed author of Anatomy of a Rose and An Obsession with Butterflies, here takes us on a tour of hunger, from eighteen hours without food to thirty-six hours to seven days and beyond. What Russell finds-both in our bodies and in cultures around the world-is extraordinary. It is a biological process that transcends nature to shape the very of fabric of societies. In a fascinating survey of centuries of thought on hunger's unique power, she discovers an ability to adapt to it that is nothing short of miraculous. From the fasting saints of the early Christian church to activists like Mahatma Gandhi, generations have used hunger to make spiritual and political statements. Russell highlights these remarkable cases where hunger can inspire and even heal, but she also addresses the devastating impact of starvation on cultures around the world today. Written with consummate skill, a compassionate heart, and stocked with facts, figures, and fascinating lore, Hunger is an inspiring window on history and the human spirit.

    This behavior is very much different from what we humans are used to dealing with in our everyday lives, so naturally this subject is quite hard to comprehend for many. We believed that the best way to introduce the subject reliably is to start at the beginning, presenting the observations, thoughts and conclusions of each of the world’s greatest physicists through their eyes, one at a time. In this way we hope that the reader may take an enjoyable journey through the strange truths of quantum theory and understand why the conclusions of these great minds are what they are. This book starts with the most general view of the world and gradually leads readers to those new, unbelievable but real facts about the very nature of our universe.

    Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and often mistakenly feared. Now Robert Peter Gale, M.D,—the doctor to whom concerned governments turned in the wake of the Chernobyl and Fukushima disasters—in collaboration with medical writer Eric Lax draws on an exceptional depth of knowledge to correct myths and establish facts. Exploring what have become trigger words for anxiety—nuclear energy and nuclear weapons, uranium, plutonium, iodine-131, mammogram, X-ray, CT scan, threats to the food chain—the authors demystify the science and dangers of radiation, and examine its myriad benefits, from safely sterilizing our food to the relatively low-risk fuel alternative of nuclear energy. This is the book for all readers who have asked themselves questions such as: What kinds of radiation, and what degree of exposure, cause cancer? What aftereffects have nuclear accidents and bombs had? Does radiation increase the likelihood of birth defects? And how does radiation work? Hugely illuminating, Radiation is the definitive road map to our post-Chernobyl, post-Fukushima world.

    This is just as well, according to Mark Lynas in Nuclear 2.0, because nuclear energy is essential to avoid catastrophic global warming. Using the latest world energy statistics Lynas shows that with wind and solar still at only about 1 percent of global primary energy, asking renewables to deliver all the world’s power is “dangerously delusional”. Moreover, there is no possibility of using less energy, he reminds us, when the developing world is fast extricating itself from poverty and adding the equivalent of a new Brazil to global electricity consumption each year. The anti-nuclear movement of the 1970s and 80s succeeded only in making the world more dependent on fossil fuels, he shows: its history is “not lit by sunshine, but shrouded in coal smoke”. Instead of making the same mistake again, all those who want to see a low-carbon future need to join forces, he insists, concluding the book with an ambitious proposal for an Apollo Program-style combined investment in wind, solar and nuclear power. Mark Lynas is an environmental writer and campaigner. His previous books have drawn attention to the perils of global warming, and he was Climate Advisor to the President of the Maldives from 2009-2011. He is a Visiting Research Associate at Oxford University’s School of Geography and the Environment, and a member of the World Economic Forum’s Global Agenda Council on Emerging Technologies. He recently featured in the movie documentary Pandora’s Promise, which inspired the writing of this book.

    Today, more than sixty years later, members of a new generation of scientists are attempting to create life from the ground up. Science has moved forward in leaps and bounds since Schrodinger's time, but our understanding of what does and does not constitute life has only grown more complex. An era that has already seen computer chip-implanted human brains, genetically engineered organisms, genetically modified foods, cloned mammals, and brain-dead humans kept alive by machines is one that demands fresh thinking about the concept of life. While a segment of our national debate remains stubbornly mired in moral quandaries over abortion, euthanasia, and other right to life issues, the science writer Ed Regis demonstrates how science can and does provide us with a detailed understanding of the nature of life. Written in a lively and accessible style, and synthesizing a wide range of contemporary research, What Is Life? is a brief and illuminating contribution to an age-old debate.
