Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    For instance, it's not hard to envision a day when websites such as Facebook or Google Maps introduce a feature that allows real-time tracking of anyone you want, based on face-recognition software and ubiquitous live video feeds.Does this scenario sound like an unconstitutional invasion of privacy? These 24 eye-opening lectures immerse you in the Constitution, the courts, and the post-9/11 Internet era that the designers of our legal system could scarcely have imagined. Professor Rosen explains the most pressing legal issues of the modern day and asks how the framers of the U.S. Constitution and the Bill of Rights would have reacted to aspects of the modern life such as full-body scans, cell phone surveillance, and privacy in cloud servers.Called "the nation's most widely read and influential legal commentator" by the Los Angeles Times, Professor Rosen is renowned for his ability to bring legal issues alive - to put real faces and human drama behind the technical issues that cloud many legal discussions. Here he asks how you would decide particular cases about liberty and privacy. You'll come away with a more informed opinion about whether modern life gives even the most innocent among us reason to worry.

    One of the first paleoanthropologists to study fossil evidence and genetic information together in order to test hypotheses about human prehistory, Professor Hawks is adept at looking at human origins not just with one lens, but with two.He has traveled around the world to examine delicate skeletal remains and pore over the complex results of genetic testing. His research and scholarship on human evolutionary history has been featured in a variety of publications, including Science, American Journal of Physical Anthropology, Slate, and Journal of Human Evolution.But more than that, Professor Hawks has crafted a course that demonstrates the passion and excitement involved in the field of paleoanthropology. With his engaging lecturing style and his use of fossil finds taken from his personal collection, Professor Hawks will capture your attention and show you all the drama and excitement to be found in eavesdropping on the latest debates about human evolutionary history.

    It ranges from the study of the universe itself to the smallest particles of matter contained within it - and everything in between. It explores everything from the big bang to theories about the end of the universe. If you want to better understand our physical world, as most of us do, gaining a basic understanding of science itself is profoundly important - yet many are intimidated by the breathtaking scope of such an endeavor. Now an award-winning science teacher has taken out the intimidation, harnessing that breathtaking scope into a series of 60 exciting, comprehensive, and accessible lectures that let you explore and understand the wealth of ideas, discoveries, and principles in all of the physical and biological sciences. You learn that understanding science comes from understanding not only its component disciplines - each of which has its own theories, pioneers, problems, and fundamental questions - but of knowing how these disciplines work with one another to create an entire mosaic of human knowledge. The lectures have been crafted to make those relationships crystal-clear, with an integrated approach that takes you through all of the major disciplines that fall under the umbrella of "science," including physics, chemistry, Earth science, geophysics, and biology. Each lecture covers one of the 60 fundamental principles of the scientific world - offering you new knowledge and insight into topics such as the scientific method, gravitation, atoms, the big bang, plate tectonics, volcanoes, proteins, ecosystems, and electricity.

    The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare in 2012 that physicists has succeeded in creating and identifying this all-important new particle, the discovery was celebrated around the world.And yet, virtually no one who read that news could tell you what, exactly, the Higgs boson was, and why its discovery was so important that we had to spend 10 billion dollars and build the single largest and most complex device in the history of mankind in order to find it. When you understand the details, this story ranks as one of the most thrilling in the history of modern science.Award-winning theoretical physicist Sean Carroll, a brilliant researcher as well as a gifted speaker who excels in explaining scientific concepts to the public, is perfectly positioned to tell this story. In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.You also get an in-depth view of the Large Hadron Collider - the largest machine ever built, and the device responsible for finally revealing the concept of the Higgs boson as reality. By the end, you'll understand how the Higgs boson verifies the final piece in the Standard Model of particle physics, and how its discovery validates and deepens our understanding of the universe.

    (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world. Welcome to the science wars—a long-running battle over the status of scientific knowledge that began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has re-emerged in today's conflict between science and religion over issues such as evolution.Professor Steven L. Goldman, whose Teaching Company course on Science in the 20th Century was praised by customers as "a scholarly achievement of the highest order" and "excellent in every way," leads you on a quest for the nature of scientific reasoning in this intellectually pathbreaking lecture series, Science Wars: What Scientists Know and How They Know It.Those who have taken Professor Goldman's previous course, which is an intensive survey of the revolution in scientific knowledge from 1900 to 2000, may have wondered: if what counts as scientific knowledge can transform so dramatically within only 100 years, what exactly is scientific knowledge? Science Wars addresses this surprisingly difficult question.Five Centuries of the Science WarsIn 24 half-hour lectures, Science Wars explores the history of competing conceptions of scientific knowledge and their implications for science and society from the onset of the Scientific Revolution in the 1600s to the present. It may seem that the accelerating pace of discoveries, inventions, and unexpected insights into nature during this period guarantees the secure foundations of scientific inquiry, but that is far from true. Consider these cases:The scientific method: In the 1600s the English philosopher Francis Bacon defined the scientific method in its classic form: the use of inductive reasoning to draw conclusions from an exhaustive body of facts. But "no scientist has ever been a strict Baconian," says Professor Goldman. "If you followed that, you would get nowhere."A "heated" debate: Around 1800 the dispute over the nature of heat was resolved in favor of the theory that heat is motion and not a substance given off during burning. But then the French mathematical physicist Joseph Fourier wrote a set of equations that accurately described how heat behaves regardless of what it "really" is, which, Fourier contended, was not a scientific question at all.Paradigm shifts: The publication in 1962 of Thomas Kuhn's The Structure of Scientific Revolutions precipitated a radical change in attitudes toward scientific knowledge, prompted by Kuhn's insight that science is not an entirely rational enterprise, and that its well-established theories (or paradigms) are overturned in a revolutionary, nonlogical process.Postmodern putdown: The postmodern attack on science as a privileged mode of inquiry made some headway in the late 20th century. But the credibility of the movement wilted in 1996, when a postmodern journal unwittingly published a spoof by physicist Alan Sokal, purporting to prove that physical theory was socially constructed. Sokal then exposed his piece as a parody.In the penultimate lecture of the course, Professor Goldman considers intelligent design—the argument that evolution can't account for the immense complexity of life and that a master designer must be at work. He approaches this topical debate by asking: What are the minimum criteria that define a hypothesis as scientific, and does intelligent design qualify? Having already covered five centuries of the science wars in the previous lectures, you will analyze this controversy with a set of tools that allows you to see the issues in a sharp, new light.What Is Reality?"Fasten your seatbelts," says Professor Goldman at the outset of Lecture 21—an advisory that applies equally to the whole course, which covers an astonishing array of ideas and thinkers. Throughout, Professor Goldman never loses his narrative thread, which begins 2,400 years ago with Plato's allegorical battle between "the gods" and "the earth giants"—between those for whom knowledge is universal, necessary, and certain; and those for whom it cannot be so and is based wholly on experience.The problem of what constitutes scientific knowledge can be illustrated with one of the most famous and widely accepted scientific theories of all time, Nicolaus Copernicus's heliostatic (stationary sun) theory of the solar system, which has undergone continual change since it was first proposed in 1543: Copernicus called for the planets to move in uniform circular motion around the sun, slightly displaced from the center. Using observations by Tycho Brahe, Johannes Kepler revised the Copernican model, discarding the ancient dogma of circular motion, which did not fit the data. Instead, he guessed that the planets in fact move in elliptical orbits. In his influential work endorsing the Copernican theory, Galileo ignored Kepler's corrections and opted for circular motion. Notoriously, the Catholic Church condemned Galileo for heresy. But the church was actually correct that he had no basis for claiming the heliocentric theory was true, rather than simply an interpretation of experience. Galileo's picture of space was superseded by Newton's and later by Einstein's, which also will doubtless be revised. Even something as basic as the elliptical motion of the planets is a vast oversimplification. There are no closed curves in space, since the solar system is moving around the center of the galaxy; the galaxy is moving within the local cluster; and the local cluster is also moving. Although we still call the conventional picture of the solar system Copernican astronomy, there is effectively no resemblance between astronomy today and Copernicus's 1543 theory of the heavens. The same is also true of other theories, such as the atomic theory of matter. All scientific theories are in a state of ceaseless revision, which raises the question of what reality "really" is. As the contemporary philosopher of science Mary Hesse has pointed out, the lesson of the history of science seems to be that the theories we currently hold to be true are as likely to be overturned as the theories they replaced!Sharpen Your Understanding of What Science IsThe uncertainty about the status of scientific knowledge and about the objectivity of the scientific enterprise led to a broad assault on science in the late 20th century by sociologists, philosophers, and historians, many connected with the postmodern movement. The lectures covering this attack and the ensuing counterattack by scientists are some of the most thrilling in the course and involve a number of figures whom Professor Goldman knows personally.Of one of the firebrands in this conflict, the late Viennese philosopher of science Paul Feyerabend, Professor Goldman says, "I myself took a seminar with Feyerabend when he was teaching at Berkeley in the early 1960s. … Feyerabend was not really off the wall, although he was often depicted that way. … He too recognized, as everyone must, that after all, science does work and science is knowledge of a sort. It's just not the absolute knowledge that scientists and philosophers have historically claimed that it is."By the time you reach the end of this course, you will understand exactly what science is, and you will be enlightened about a fascinating problem that perhaps you didn't even know existed. "There have been a raft of popular books about what scientists know," says Professor Goldman, "but to the best of my knowledge, there is not a single one of these popular books that focuses centrally on the question of how scientists know what they know."This course serves as that book.Course Lecture Titles1.

    The truth is, while metaphysics is among the oldest strands of philosophical thought—an inquiry into the very nature ofreality—metaphysics is also on the cutting edge of today’s scientific discoveries.

    The answer: with the essentials. Now, finally satisfy your desire for scientific inquiry in a way that makes this enormous field accessible, understandable, and undeniably captivating. Professor Viskontas boils down the scientific world into 12 key concepts every educated person should know. Devoting two lectures to each concept to give you more time to engage with it, her 24-lecture series is an engaging and enlightening introduction to everything from the behavior of subatomic particles to the latest theories about the Big Bang. Throughout, you'll get accessible looks at key building blocks of scientific knowledge, including brain plasticity, fluid mechanics, electromagnetism, genetics, quantum theory, emergence, evolution, thermodynamics, the Big Bang, and the nature of matter. Each concept is presented in a clear, concise way that will inform and delight you, and that will give you the opportunity to probe the invisible life of living cells, visit the universe seconds after its birth, and much more. Concepts that may have eluded you in school, that you may not be familiar with, or that you simply never appreciated for their intricate beauty are now brought to vivid life in a way that sticks. Welcome to the world of science - reduced to its powerful essence.

    But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list.  Maxwell, an unassuming Victorian Scotsman, explained how we perceive colour. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.   Along the way, he set up one of the most enduring challenges in physics, one that has taxed the best minds ever since. ‘Maxwell’s demon’ is a tiny but thoroughly disruptive thought experiment that suggests the second law of thermodynamics, the law that governs the flow of time itself, can be broken. This is the story of a groundbreaking scientist, a great contributor to our understanding of the way the world works, and his duplicitous demon.

    Every night we surrender it gratefully, only to get it back in the morning. We recognize that we have it, but we can never be sure anyone else does. Consciousness, this unique and perplexing mental state, has been the subject of debate for philosophers and scientists for millennia. And while it is widely agreed within contemporary philosophy that consciousness is a problem whose solutions are likely to determine the fate of any number of other problems, there is no settled position on the ultimate nature of consciousness.What is the most promising way to study this subject? What are the implications that arise from the fact that we have consciousness? What are the ethical and moral issues raised by its presence—or its absence? Questions like these are at the heart of Consciousness and Its Implications, 12 thought-provoking lectures delivered by distinguished philosopher and psychologist Daniel N. Robinson. Rather than merely explain away consciousness, or hide behind such convenient slogans as "it's all in your brain," Professor Robinson reviews some of the special problems that philosophers, psychologists, scientists, and doctors face when taking on such a vexing topic.What Is Consciousness? Much of what we do every day is done without our being directly conscious of the steps taken to complete the task: riding a bicycle, taking a walk, humming a tune. But as natural as this state is, it stands as a very serious threat to any number of core convictions and assumptions in both philosophy and science. One of the overarching goals of this intriguing course is to make clear just what about consciousness serves as such a challenge to these convictions and assumptions.But what makes Consciousness and Its Implications so engaging is more than just the nature of the questions it poses and the issues it tackles. It's the way in which Professor Robinson, the consummate teacher and scholar, conveys this goal in four main points, each of which you explore in depth in these lectures.Consciousness seems to require, for its full understanding, a science not yet available. What distinguishes consciousness from all else is its phenomenology—that is, the act of being conscious is different from all other facts of nature. Conscious awareness is a power that, at times, can be so strong as to greatly affect our senses. The powers of consciousness vary over the course of a lifetime; as such, they can become subject to disease and defect.Throughout the course, Professor Robinson brings this riveting topic vividly to life with real-world examples and striking anecdotes. Review the case of Deep Blue, the IBM computer that in 1997 shocked the world by defeating a human, the chess grand master Garry Kasparov. Does Deep Blue's ability to "outsmart" a human being constitute a kind of consciousness? Or is it a reflection of the human minds that created this complex computer? Consider the case of the sleepwalker, who moves around with purpose and mimics behaviors we see in everyday life, but can remember nothing upon awakening. How does this mental state relate to human consciousness? What would be lost if we lived our entire lives as sleepwalkers?Study the case of a comatose patient who lives in an unbroken sleep state but, after a miraculous recovery, recalls having heard doctors speak about her. How do we interpret this patient's ability to perceive the surrounding world while in a coma? Does the patient's experience reflect some in-between mental state we've yet to define? Look at the case of a child with autism who can perform complicated mental tasks but lacks the most basic human attribute: empathy. How does this inability to imagine other minds affect the child's capacity to enjoy the full experience of human consciousness? Using compelling examples such as these, Professor Robinson weaves a riveting tale of the human condition that will change the way you think about your own mind.Professor Robinson also draws on the wisdom of the world's greatest thinkers—from the ancient Greeks to today's top scientists—to shed light on some of the ethical debates involved in any examination of consciousness. These include John Locke, whose famous "Prince and the Cobbler" hypothesis raised questions about the relationship between one's personal identity and one's body; Ludwig Wittgenstein, whose "Beetle in a Box" scenario holds implications for how we define consciousness both inside and outside ourselves; and Aristotle, who led a pointed discussion on the relationship between the physical world and what he referred to as "real being."You also enter the lab and explore the impact of modern physics and medicine on our understanding of the self. Pondering questions ranging from the most fundamental—"Why are we here?"—to contemporary quandaries about artificial intelligence and the medical decision to prolong life, you'll gain new insights into the complexity of how great minds define consciousness.Consciousness and Its Implications is a chance for you to view this deep and profound subject from all angles. A distinguished scholar in philosophy and neuropsychology, Professor Robinson incorporates many disciplines—psychology, physics, philosophy, medicine—to explore these abiding questions. So embark on a challenging and wholly satisfying exploration of this unique, mysterious, and essential mental faculty. The knowledge you'll gain in this course is not only intriguing—it is crucial to understanding the nature of humanity and the social and ethical obligations that define us all.
