The Higgs Boson and Beyond


Sean Carroll - 2015
    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.

The Learning Brain


Thad A. Polk - 2018
    This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? And how do external factors like traumatic injuries and mood affect our gray matter? The answers to these questions are merely the tip of the iceberg in The Learning Brain.These 24 half-hour lectures offer in-depth and surprising lessons about how the brain learns and how we can optimize that learning. Begin your journey by focusing on which parts of the brain are responsible for different kinds of memory, from personal experiences and memorized facts to short-term memory, and how these systems work on a psychological and biological level. Then, discover how to better absorb and retain all kinds of memories in all stages of life. This course is chock-full of valuable information, whether you're learning a new language at 60 or discovering calculus at 16. If you need better study habits, struggle with learning a new skill, or just worry about memories fading with age, The Learning Brain will provide illuminating insights.Take this journey with Thad Polk, professor of psychology at the University of Michigan, whose well-organized curriculum and relaxed teaching style ease you into intricate aspects of learning science, including the underlying cognitive and neural mechanisms involved. Professor Polk's credentials in psychology and over 20 years' experience in education shine through every lecture of The Learning Brain as he firmly supports this rigorous exploration with scientific studies conducted over the last several decades of neuroscientific research.Listening Length: 12 hours and 23 minutes

Biological Anthropology: An Evolutionary Perspective


Barbara J. King - 2002
    King (William and Mary University) delves into the story of how, why, where, and when we became human. These lectures will help you understand the forces that have shaped, and continue to shape, our species. "An evolutionary perspective on human behavior," notes Dr. King, "results in more than just knowledge about dates and sites when and where specific evolutionary milestones likely occurred." "It is also a window on the past and future of our species. An entirely new way of thinking comes into focus when we consider the human species within an evolutionary perspective."A Century of ScholarshipWhile covering these subjects in this 24-lecture series, Dr. King synthesizes the best that more than a century of scientific scholarship has to offer across a variety of disciplines. Biological anthropologists study primate anatomy and behavior both to understand evolution and to learn more about our common ancestor. Biological anthropologists are joined by molecular anthropologists to better understand hominids by studying fossils, ancient skeletal remains, and lifestyle information such as cave art and stone tools. Case Studies that Clarify Evolution and Its Power Dr. King begins by explaining key mechanisms through which evolution functions, citing famous and definitive case studies that demonstrate these forces. In one such landmark study, for example, biologists Peter and Rosemary Grant returned to the Galapagos Islands more than 100 years after Darwin's first voyage to conduct research on island finches. In 1977, a drought-induced scarcity of soft, edible seeds brought forth in the very next generation a population of finches with larger, stronger beaks capable of crushing larger, tougher seeds. Extraordinarily, in 1985, heavy rains produced a surplus of softer seeds, and natural selection produced a succeeding generation of the smaller-beaked variety. Evolution had occurred in two different directions within a decade. This "natural selection" is the theoretical tool of evolution, which helps us make sense of these facts. Why Evolution Remains Important to Us Today Perhaps the greatest measure of this theory's power is its relevance to our lives today. - Did you know that the gene which causes sickle cell anemia must be inherited from both parents to cause the disease but the disease does not occur when only a single gene is inherited? - Or that the single gene, in fact, affords protection from malaria? Or that race, a category so securely ingrained in our consciousness, is practically meaningless in biological terms? - Or how to evaluate the claim that a gene can be responsible for a certain personality trait? A Glimpse Into Our Selected Primate Heritage With an understanding of the basic mechanisms of evolutionary change in hand, the course looks at how our ancient primate ancestors adapted. Consider the anatomical features we share with monkeys, great apes, and other primates. Our large brains, grasping hands, and forward-facing eyes allowing us to perceive depth are critical to the way we function in the world. Yet the fossil record tells us that some 70 million years ago these distinctive primate features did not exist. What caused the first primates to emerge from existing mammalian populations? One proposed solution was that the appearance of insects living in the lower canopies of trees offered a plentiful food resource to those species adapted to procure it. Could depth perception and grasping ability have provided an advantage here, and hence been naturally selected? This is the function of biological anthropology: confronting the facts, then suggesting and testing possibilities. A Course as Much About the Present as the PastWith so much of evolutionary history taken up with the past, the insights gained in these lectures may tempt you to add questions of your own: - Is human evolution still a force in today's world? Hasn't our modern, mobile culture rendered evolution irrelevant? - In fact, human evolution is a stronger force than ever, interacting with human culture in complex ways. Issues such as obesity, AIDS, and genetics are all discussed. And you may well find these lectures opening your eyes to the extraordinary ways in which the biological power of natural selection is still at work in the world today. Course Lecture Titles1.

Privacy, Property, and Free Speech: Law and the Constitution


Jeffrey Rosen - 2012
    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.

The Real History of Secret Societies


Richard B. Spence - 2019
    In this course brought to you in partnership with HISTORY, you will be visiting some of history’s deepest rabbit-holes, across centuries and continents, in search of secret societies in all their varieties. You will journey to some very dark places, and frankly some odd and sometimes silly ones as well. During 24 eye-opening lectures, Dr. Richard B. “Rick” Spence, Professor of History at the University of Idaho, guides you through the fascinating, often mystifying - sometimes disturbing - world of brotherhoods, sisterhoods, orders, cults, and cabals that have influenced human culture from ancient times to the present.You’ll understand how and why secret societies have attracted some of history’s most brilliant, and some of its most evil, minds. Often demonized by their enemies, many secret societies have become the stuff of myths and conspiracy theories. Why do they exist? And when they are invented or imagined, why would someone pretend they exist? What do secret societies believe? Who do they recruit? Most important, what influence do they have? Buckle up and get ready to find out.

Capitalism vs. Socialism: Comparing Economic Systems


Edward F. Stuart - 2018
    After much consideration, we determined that it actually would be more beneficial to create a course that compares and contrasts the two major global economic theories, examining them in ways that move past the polemics many of us are used to and looking at these systems as they relate to one another and the world at large.Politics and economics are inextricable, so it can be difficult to find the right person to tackle such a complex and often polarizing subject as objectively as possible. Luckily, we found Professor Edward Stuart, an economist and teacher who specializes in comparative economics. Professor Stuart brings not only economic expertise, but personal experience gleaned from teaching, traveling, and consulting all over the world, and it is this wide lens of experience that helps make Capitalism vs. Socialism such an engaging new entry in our library of courses.

The Skeptic’s Guide to the Great Books


Grant L. Voth - 2011
    Moby-Dick. War and Peace. Ulysses. These are just four of what are considered the "Great Books"—works of literature that have been singled out as essential parts of a well-read individual's reading list. The only problem: The "Great Books" can be daunting, intimidating, and oftentimes nearly impossible to get through.The truth of the matter is that there is so much more to literature than these giants of the Western canon. In fact, you can get the same pleasures, satisfactions, and insights from books that have yet to be considered "great." Books that are shorter, more accessible, and less dependent on classical references and difficult language. Books that, in the opinion of popular Great Courses Professor Grant L. Voth of Monterey Peninsula College, "allow you to connect with them without quite so many layers of resistance to work through."When you take this skeptical approach to the "Great Books," you open yourself up to works that are just as engaging, just as enjoyable, and—most important—just as insightful about great human themes and ideas as anything you'd encounter on a college-level reading list. Professor Voth's course, The Skeptic's Guide to the Great Books, is your opportunity to discover new literary adventures that make worthy substitutes to works from the Western literary canon. In these 12 highly rewarding lectures, you'll get an introduction to 12 works that redefine what great literature is and how it can reveal startling truths about life—all without being such a chore to read.

Philosophy of Science


Jeffrey L. Kasser - 2006
    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.
