For more than two centuries, our understanding of the laws of nature expanded rapidly. But today, despite our best efforts, we know nothing more about these laws than we knew in the 1970s. Why is physics suddenly in trouble? And what can we do about it?One of the major problems, according to Smolin, is string theory: an ambitious attempt to formulate a “theory of everything” that explains all the particles and forces of nature and how the universe came to be. With its exotic new particles and parallel universes, string theory has captured the public’s imagination and seduced many physicists.But as Smolin reveals, there’s a deep flaw in the theory: no part of it has been tested, and no one knows how to test it. In fact, the theory appears to come in an infinite number of versions, meaning that no experiment will ever be able to prove it false. As a scientific theory, it fails. And because it has soaked up the lion’s share of funding, attracted some of the best minds, and effectively penalized young physicists for pursuing other avenues, it is dragging the rest of physics down with it.With clarity, passion, and authority, Smolin charts the rise and fall of string theory and takes a fascinating look at what will replace it. A group of young theorists has begun to develop exciting ideas that, unlike string theory, are testable. Smolin not only tells us who and what to watch for in the coming years, he offers novel solutions for seeking out and nurturing the best new talent—giving us a chance, at long last, of finding the next Einstein.

    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.

    This is a world tour of prehistory with profound links to who we are and how we live today.2.5 Million Years of HistoryThis 36-lecture narrative covers human prehistory from our beginnings more than 2.5 million years ago up to and beyond the advent of the world's first preindustrial civilizations.Due to the large spans of time and geography covered in this series, these lectures are divided into six sections:Section I: BeginningsThis section surveys the archaic world of the first humans, you travel into the remote past, learning why the late Harvard biologist Stephen Jay Gould was probably right to observe that we all come from the same African twig on the bushy tree of human evolution.You examine prehistory from Australopithecus africanus through Homo habilis (the first tool-making hominid), and Homo erectus (whose remains were first found on Java but whose origins lie in Africa) through the hardy Neanderthals who lived and hunted successfully in Europe despite the bitter grip of the last Ice Age 100,000 and more years ago. You focus on the first human settlement of Africa as early as 800,000 years ago.Section II: Modern HumansThis section tells the story of the great diaspora of anatomically modern humans in the late Ice Age. Whether and how these modern humans spread from the African tropics into southwestern Asia and beyond remains one of the great controversies among scholars of prehistory.You follow Homo sapiens sapiens north into Europe some 45,000 years ago. You meet the Cro-Magnons, among the first known artists as well as hunter-gatherers, who exhibited degrees of spiritual awareness, social interaction, and fluid intelligence.You venture into the frigid open plains of the Ukraine and Eurasia, where big-game hunters flourished in spite of nine-month winters. Moving to the Americas, debate over the origins of the first human settlement continues.Section III: Farmers and HerdersThis section describes perhaps the most important development in all human prehistory: the beginnings of agriculture and animal domestication.This defining chapter began about 12,000 years ago, when hunter-gatherers in the Near East broke from the long human tradition of intensely mobile foraging and turned to more settled ways of life built around cultivating cereal grains or tending animals.Section IV: Eastern Mediterranean CivilizationsProfessor Fagan describes early civilizations in an increasingly complex eastern Mediterranean world, discussing many theories accounting for the appearance of urban civilization and overall attributes of preindustrial civilizations.You examine Sumerian civilization in Mesopotamia and the intricate patchwork of city-states between the Tigris and Euphrates Rivers. You explore ancient Egypt, the Minoan civilization of Crete, the Mycenaeans, and the Hittites.You learn about the Uluburun shipwreck of southern Turkey, a sealed capsule of international trade from 3,000 years ago.Section V: Africans and AsiansYou analyze the beginnings of South Asian civilization and the mysterious Harappan civilization of the Indus, which traded with Mesopotamia. Professor Fagan resumes the story of South Asian civilization after the collapse of the Harappan and shows how Mauryan rulers on the Ganges encouraged trading much farther afield.You see the impact of monsoons which revolutionized maritime trading among Africa, India, and Southeast Asia, and explore Meroe, Aksum, and the coastal civilization of East Africa.Several lectures cover the beginnings of civilization in China and Southeast Asia.Section VI: Ancient AmericansProfessor Fagan takes you into sophisticated chiefdoms and civilizations that developed in the Americas over the past 3,500 years, including Pueblo cultures of the North American Southwest and the Mississippian culture of the South and Southeast. You learn about Mesoamerican civilization, primordial Olmec culture of the lowlands, and the spectacular ancient Maya civilization.Moving to the highlands, you visit the city-states of Monte Albán in the Valley of Oaxaca and Teotihuacán near the Valley of Mexico. Professor Fagan also describes the rise of Aztec civilization, followed by a journey to the Andes. Finally, you explore the southern highlands, with the rise of Tiwanaku near Lake Titicaca, the Chimu civilization of the coast, and the huge Inka empire.The series closes by analyzing the closing centuries of prehistoric times during the European age of discovery and summarizing the main issues and themes of the course: * What was involved in the archaic world * The appearance and spread of modern humans * Food production * The development of states.

    More than 2,500 years later, the issues they pondered continue to challenge, fascinate, and instruct us. Is reality stable and permanent or is it always changing? Are ethical values like justice and courage relative? Or are values "absolute"—simply and forever right and true? What is justice? What is happiness? How shall we best live our lives?An Introduction to Greek Philosophy beckons you to join this eternal discussion. For that is what this subject truly is: a conversation among thinkers that has continued through the centuries and remains accessible to us today. You find it constantly stimulating, sometimes controversial, and nearly always remarkably relevant.A Hunger for Reasons, not Myths or BeliefsProfessor David Roochnik has organized this series of 24 lectures as a "dialectical" approach (the word comes from the Greek dialegesthai: to converse). The philosophers are presented as if they were participating in a conversation. In this way, the course unfolds in a manner similar to the actual development of Greek philosophy.In this course, you study the development of Greek philosophy, meet its major thinkers, and explore the issues and ideas that concerned them. For example the first real philosophers were the Presocratics—literally, the philosophers who lived before Socrates. They included Thales of Miletus (585 B.C.E.–?), Anaximander (610–546), Anaximenes (approx. 550), Xenophanes (approx. 570) and Pythagoras (approx. 570–500).The Presocratics rejected myth and divine inspiration—such as had been embodied in the works of Homer and in Hesiod's creation story, the Theogony—as valid explanations of reality. Instead, they insisted that true understanding always requires a logos, a rational explanation (hence such English words as "psychology" and "biology").The Presocratics were concerned with issues such as identifying the arche or "Being": the thing that is the origin of all other things. They also introduced sophistic relativism, the notion that truth, goodness, and all other values were relative, depending entirely on the person or group that held them. This concept would become a major point of debate for the Greeks and for the ages.Are We Footnotes to Plato?The heroes of this course, and certainly of Greek philosophy, are Plato (429–347 B.C.E.) and his student, Aristotle (384–322 B.C.E.). Unlike the Presocratics, who wrote too little, Plato and Aristotle were prolific authors. Both argued against relativism and instead were staunch objectivists who believed that certain important values were absolutely and universally true. And both left a staggering mark on history.Alfred North Whitehead, the great 20th-century British philosopher, said, "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." In the Middle Ages, Aristotle was held in such high esteem that he was simply known as "the philosopher."Among Plato's many contributions to philosophy is his ingenious device for the examination of ideas: his written dialogues. In them, Plato never uses his own voice. Instead, the dialogues take place among a changing cast of characters, and Socrates is the most notable among them. The effect is to invite us to take part in the conversation and, ultimately, to become philosophers.You study Plato's dialogues as well as his notion of the Forms. This was his response to relativism and proposed that every virtue and value has an absolute and perfect Form, which humans understand even before birth.Greek philosophy can be said to culminate with Aristotle, who wrote treatises on a breathtaking range of subjects. He is said to be the first to view knowledge as being divided into specific disciplines such as biology or astronomy. The university was later modeled on this approach. More than any other philosopher, Aristotle synthesized the views that preceded him.For Aristotle, one value was foremost and was contained in everything, from the tiniest organisms to the phenomena of fire to human beings: purpose. Everything has a purpose that can be recognized and objectively defined, and that gives meaning to life. You explore the details and rationale of Aristotle's teleological—or purposive—world-view, one of the most significant in history.An Invitation to ThinkIn this course, you not only learn about Greek philosophy but, to some extent, how to do it. Professor Roochnik emphasizes that Greek philosophy is ultimately not about facts or answers but about the give-and-take of ideas.By the end of these lectures, you will understand how Greek philosophy still heavily influences our view of life. We live today, Professor Roochnik maintains, at a time that is shaped by Presocratic, relativistic philosophy. Contemporary thinkers, and often the average person, have great difficulty finding objective truth or meaning in life.What have we lost in turning away from the world of Plato and Aristotle—a world where everything has a place and a purpose and life is saturated with value and meaning?On the other hand, what would we lose if we returned to that world?These are a few of the many questions that will give you ample food for thought. For the Greeks, that was the greatest feast of all.

    A man of faith ordained in the Protestant tradition, Heino Falcke wrestles with the ways in which black holes force us to confront the boundary where human life ends and the celestial begins. He also ponders why black holes are difficult for most of us to understand—comparing it to our inability to envisage our own inevitable death.Black holes develop in outer space when a massive star dies, and its matter is condensed. That extreme amount of mass contained in a small space generates a gigantic amount of gravitational force, allowing the black hole to suck up everything that comes near, including light. These astronomical wonders are the subject of our greatest scientific and philosophical theorizing—the journey to a black hole would be the journey to the end of time itself. In this way, Falcke regards them as the most exquisite representations of fear, death . . . and, surprisingly, the divine.Empirical and profound, A Light in the Darkness is the first work to examine both the physical nature and spiritual meaning of black holes, those astrophysical mysteries Falcke, calls “the epitome of merciless destruction.”

    His language and culture - those of Elizabethan England - are greatly different from our own, and his poetry, thick with metaphorical imagery and double meanings, can be hard to penetrate.Yet the keys to understanding Shakespeare are written into the plays themselves. If you can learn to recognize the playwright's own clues, you'll become able to engage meaningfully with his language, to follow the plot structures and themes that drive his plays, and to track the development of his characters.Over the course of 24 lectures, this innovative and penetrating exploration of Shakespeare's plays reveals how to enter Shakespeare's dramatic world, how to grasp what's happening in any of his plays, and how to enjoy them fully both on the page and the stage.Under Professor Conner's expert guidance, shaped by decades of studying and performing Shakespeare, you learn more than 40 interpretive tools, drawn from the texts themselves, that give you direct insight into the plays. These guiding principles allow you to follow the narratives of the plays as they unfold, with a clear understanding of how the plays function and fit together.The professor also reveals fascinating details of Shakespeare's era, which shed further light on the plays and the way his contemporary audiences perceived them.This course builds the skills that allow you to reach your own understanding of the plays - to deeply comprehend Shakespeare's transcendent poetic language, the spellbinding world of his great characters and stories, and his revelatory reflections on human experience.Disclaimer: Please note that this recording may include references to supplemental texts or print references that are not essential to the program and not supplied with your purchase.©2013 The Teaching Company, LLC (P)2013 The Great Courses

    Kasser launches an ambitious and exciting inquiry into what makes science science, using the tools of philosophy to ask: * Why is science so successful? * Is there such a thing as the scientific method? * How do we distinguish science from pseudoscience? * Is science rational, cumulative, and progressive? Focusing his investigation on the vigorous debate over the nature of science that unfolded during the past 100 years, Professor Kasser covers important philosophers such as Karl Popper, W. V. Quine, Thomas Kuhn, Paul Feyerabend, Imre Lakatos, Carl Hempel, Nelson Goodman, and Bas van Fraassen.All of these thinkers responded in one way or another to logical positivism, the dominant movement influencing the philosophy of science during the first half of the 20 th century. Logical positivism attempted to ground science exclusively in what could be known through direct experience and logic.It sounds reasonable, but logical positivism proved to be riddled with serious problems, and its eventual demise is an object lesson in how truly difficult it is—perhaps impossible—to secure the logical foundations of a subject that seems so unassailably logical: science.

    A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013. Its superconducting magnets guide two beams of protons in opposite directions around the track. After accelerating the beams to 99.9999991 percent of the speed of light, it collides the protons head-on, annihilating them in a flash of energy sufficient—in accordance with Einstein’s elegant statement of mass-energy equivalence, E=mc2—to coalesce into a shower of particles and phenomena that have not existed since the first moments of creation. Within the LHC’s detectors, scientists hope to see empirical confirmation of key theories in physics and cosmology.In telling the story of what is perhaps the most anticipated experiment in the history of science, Amir D. Aczel takes us inside the control rooms at CERN at key moments when an international team of top researchers begins to discover whether this multibillion-euro investment will fulfill its spectacular promise. Through the eyes and words of the men and women who conceived and built CERN and the LHC—and with the same clarity and depth of knowledge he demonstrated in the bestselling Fermat’s Last Theorem—Aczel enriches all of us with a firm grounding in the scientific concepts we will need to appreciate the discoveries that will almost certainly spring forth when the full power of this great machine is finally unleashed.Will the Higgs boson make its breathlessly awaited appearance, confirming at last the Standard Model of particles and their interactions that is among the great theoretical achievements of twentieth-century physics? Will the hidden dimensions posited by string theory be revealed? Will we at last identify the nature of the dark matter that makes up more than 90 percent of the cosmos? With Present at the Creation, written by one of today’s finest popular interpreters of basic science, we can all follow the progress of an experiment that promises to greatly satisfy the curiosity of anyone who ever concurred with Einstein when he said, “I want to know God’s thoughts—the rest is details.”

    Bad arguments, fallacious reasoning, misleading language, and built-in cognitive biases are all traps that keep us from rational decision making-to say nothing of advertisers and politicians who want to convince us with half-truths and empty rhetoric. The Philosopher's Toolkit: How to Be the Most Rational Person in Any Room offers the skills to do just that. Taught by award-winning Professor Patrick Grim of the State University of New York at Stony Brook, this applied philosophy course arms you against the perils of bad thinking and supplies you with an arsenal of strategies to help you be more creative, logical, inventive, realistic, and rational in all aspects of your daily life, from the office to the voting booth.

    Taking in 440 sextillion kilometres of space and 13.8 billion years of time, it is physically impossible to make a better map: we will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology, on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct. The map contains anomalies that challenge our understanding of the universe. It will force us to revisit what is known and what is unknown, to construct a new model of our universe. This is the first book to address what will be an epoch-defining scientific paradigm shift. Stuart Clark will ask if Newton's famous laws of gravity need to be rewritten; if dark matter and dark energy are just celestial phantoms? Can we ever know what happened before the Big Bang? What’s at the bottom of a black hole? Are there universes beyond our own? Does time exist? Are the once immutable laws of physics changing?
