He was one of the leading pioneers of the greatest revolution in twentieth-century science: quantum mechanics. The youngest theoretician ever to win the Nobel Prize for Physics, he was also pathologically reticent, strangely literal-minded and legendarily unable to communicate or empathize. Through his greatest period of productivity, his postcards home contained only remarks about the weather.Based on a previously undiscovered archive of family papers, Graham Farmelo celebrates Dirac's massive scientific achievement while drawing a compassionate portrait of his life and work. Farmelo shows a man who, while hopelessly socially inept, could manage to love and sustain close friendship.The Strangest Man is an extraordinary and moving human story, as well as a study of one of the most exciting times in scientific history.'A wonderful book . . . Moving, sometimes comic, sometimes infinitely sad, and goes to the roots of what we mean by truth in science.' Lord Waldegrave, Daily Telegraph

    But is this image really accurate?Recent scholarship examining the Persian Empire from the Persian perspective has discovered a major force that has had a lasting influence on the world in terms of administration, economics, religion, architecture, and more. In fact, the Persian Empire was arguably the world's first global power—a diverse, multicultural empire with flourishing businesses and people on the move. It was an empire of information, made possible by a highly advanced infrastructure that included roads, canals, bridges, and a courier system. And the kings of Persia's Achaemenid dynasty —Cyrus, Darius, Xerxes, and others—presided over an empire that created a tremendous legacy for subsequent history.The Persian Empire is your opportunity to see one of the greatest empires in the ancient world from a fresh new perspective: its own. Over the span of 24 fascinating lectures, Professor John W. I. Lee of the University of California, Santa Barbara—a distinguished teacher and an expert on the long-buried secrets of the ancient world—takes the role of a history detective and examines Persian sources to reveal what we now know about this grand civilization. Tapping into the latest scholarship on the Persian Empire, this course is sure to fill in some critical gaps in your understanding and appreciation of the sweep of ancient history and its undeniable effect on later civilizations—including our own.

    He is the author of several books and dozens of scholarly articles, most recently, The Confederate War. He is a founder and was first president of the Association for the Preservation of Civil War Sites. Between 1861 and 1865, the clash of the greatest armies the Western hemisphere had ever seen turned small towns, little-known streams, and obscure meadows in the American countryside into names we will always remember. In those great battles streams ran red with blood, and the United States was truly born.Leading Civil War historian Professor Gary W. Gallagher richly details the effects of the Civil War on all Americans. You'll learn how armies were recruited, equipped, and trained. You'll learn about the hard lot of prisoners. You'll hear how soldiers on both sides dealt with the rigors of camp life, campaigns, and the terror of combat. You'll understand how slaves and their falling masters responded to the advancing war. And you will see the desperate price paid by the families so many left behind.

     It was an ancient puzzle that stymied history's greatest minds: How did the fossils of seashells find their way far inland, sometimes high up into the mountains? Fossils only made sense in a world old enough to form them, and in the seventeenth century, few people could imagine such a thing. Texts no less authoritative than the Old Testament laid out very clearly the timescale of Earth's past; in fact one Anglican archbishop went so far as to calculate the exact date of Creation...October 23, 4004, B.C. A revolution was in the making, however, and it was started by the brilliant and enigmatic Nicholas Steno, the man whom Stephen Jay Gould called "the founder of geology." Steno explored beyond the pages of the Bible, looking directly at the clues left in the layers of the Earth. With his groundbreaking answer to the fossil question, Steno would not only confound the religious and scientific thinking of his own time, he would set the stage for the modern science that came after him. He would open the door to the concept of "deep time," which imagined a world with a history of millions or billions of years. And at the very moment his expansive new ideas began to unravel the Bible's authoritative claim as to the age of the Earth, Steno would enter the priesthood and rise to become a bishop, ultimately becoming venerated as a saint and beatified by the Catholic Church in 1988. Combining a thrilling scientific investigation with world-altering history and the portrait of an extraordinary genius, "The Seashell on the Mountaintop" gives us new insight into the very old planet on which we live, revealing how we learned to read the story told to us by the Earth itself, written in rock and stone.

    Now Wright attempts something even more ambitious: explaining the direction of evolution and human history–and discerning where history will lead us next.In Nonzero: The Logic of Human Destiny, Wright asserts that, ever since the primordial ooze, life has followed a basic pattern. Organisms and human societies alike have grown more complex by mastering the challenges of internal cooperation. Wright's narrative ranges from fossilized bacteria to vampire bats, from stone-age villages to the World Trade Organization, uncovering such surprises as the benefits of barbarian hordes and the useful stability of feudalism. Here is history endowed with moral significance–a way of looking at our biological and cultural evolution that suggests, refreshingly, that human morality has improved over time, and that our instinct to discover meaning may itself serve a higher purpose. Insightful, witty, profound, Nonzero offers breathtaking implications for what we believe and how we adapt to technology's ongoing transformation of the world.From the Trade Paperback edition.

    Yet as bestselling author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in hand, Bennett begins an entertaining introduction to Einstein's theories, describing the amazing phenomena readers would actually experience if they took a trip through a black hole.The theory of relativity also gives us the cosmic speed limit of the speed of light, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: e = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe, and it is not "just a theory: " every major prediction of relativity has been tested to exquisite precision and its practical applications include the Global Positioning System (GPS). Bennett proves anyone can understand the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important not only to science but also to the way we view ourselves as human beings.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    

    It starts in your mother's womb, accelerates to high speed in infancy and childhood, and continues through every age, whether you're actively engaged in mastering a new skill, intuitively discovering an unfamiliar place, or just sleeping, which is fundamental to helping you consolidate and hold on to what you've learned. You are truly born to learn around the clock.But few of us know how we learn, which is the key to learning and studying more effectively. For example, you may be surprised by the following:People tend to misjudge what they have learned well, what they don't yet know, and what they do and do not need to practice.Moments of confusion, frustration, uncertainty, and lack of confidence are part of the process of acquiring new skills and new knowledge.Humans and animals explore their worlds for the sake of learning, regardless of rewards and punishment connected with success.You can teach an old dog new tricks. In fact, older learners have the benefit of prior knowledge and critical skills—two advantages in learning.Shedding light on what's going on when we learn and dispelling common myths about the subject, How We Learn introduces you to this practical and accessible science in 24 half-hour lectures presented by Professor Monisha Pasupathi of the University of Utah, an award-winning psychology teacher and expert on how people of all ages learn.

    That was indeed what life was like in the earliest settlements, but by 5,000 years ago, life in some places had become much more sophisticated than we might think. Impressive achievements - like stepped temples that towered like mountains, elaborate palaces (some with bathrooms and plumbing), and complex houses - were also a part of life for people who lived in cities that arose thousands of years ago, particularly in the fertile region that emerged along the Tigris and Euphrates Rivers.Welcome to Mesopotamia, the ancient name for the region that is now Iraq, a remarkably advanced civilization that flourished for two-thirds of the time that civilization has existed on Earth. Mesopotamians mastered irrigation agriculture; built the first complex urban societies; developed writing, literature, and law; and united vast regions through warfare and diplomacy. While civilizations like Greece and Rome have an unbroken tradition of written histories, the rich history of Mesopotamia has only been recently rediscovered, thanks to the decipherment of Mesopotamia's cuneiform writing less than 200 years ago. In this 24-lecture course taught by Professor Podany, you'll fill in the blanks of your historical understanding as you witness a whole new world opening before your eyes.Riveting stories about kings and priestesses as well as ordinary people from all walks of life transport you back in time, giving you invaluable insights into the history of a landmark region that has long been known as the cradle of civilization.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Professor Hans-Friedrich Mueller, of Union College in Schenectady, New York, makes this ancient world come alive in 24 lectures with captivating stories of intrigue, artifacts, illustrations, and detailed descriptions from primary sources of intriguing personalities. In the ancient Mediterranean area, religion was not separate from daily life. To the contrary, religion was daily life. The many dozen gods of this ancient world were everywhere, with spirits inhabiting every crack and crevice of life. These polytheists believed they had a strict contract with their deities: If they took care of their gods, their gods would take care of them (or at least not harm them). Consequently, they built extraordinary temples to honor their deities, brought food and wine to them, sacrificed animals for them, and held sacred meals with their gods. In fact, they followed numerous rules and regulations that circumscribed almost all aspects of life both inside and outside the home - anything and everything to keep the gods happy. Consequently, the religious practices of the ancient Mediterranean make a wonderful lens through which to develop a deeper understanding of their world.

    He shows how plants and animals (including humans) have evolved together as components of a worldwide learning machine. He describes the network of life on Earth as one that is, in fact, a complex adaptive system, a global brain in which each of us plays a sometimes conscious, sometimes unknowing role. and he reveals that the World Wide Web is just the latest step in the development of this brain. These are theories as important as they are radical. Informed by twenty years of interdisciplinary research, Bloom takes us on a spellbinding journey back to the big bang to let us see how its fires forged primordial sociality. As he brings us back via surprising routes, we see how our earliest bacterial ancestors built multitrillion-member research and development teams a full 3.5 billion years ago. We watch him unravel the previously unrecognized strands of interconnectedness woven by crowds of trilobites, hunting packs of dinosaurs, feathered flying lizards gathered in flocks, troops of baboons making communal decisions, and adventurous tribes of protohumans spreading across continents but still linked by primitive forms of information networking. We soon find ourselves reconsidering our place in the world. Along the way, Bloom offers us exhilarating insights into the strange tricks of body and mind that have organized a variety of life forms: spiny lobsters, which, during the Paleozoic age, participated in communal marching rituals; and bees, which, during the age of dinosaurs, conducted collective brainwork. This fascinating tour continues on to the sometimes brutal subculture wars that have spurred the growth of human civilization since the Stone Age. Bloom shows us how culture shapes our infant brains, immersing us in a matrix of truth and mass delusion that we think of as reality.Global Brain is more than just a brilliantly original contribution to the ongoing debate on the inner workings of evolution. It is a grand vision, says the eminent evolutionary biologist David Sloan Wilson, a work that transforms our very view of who we are and why.
