Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee

    More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as quickly, continued on its journey out into the beyond.Nothing like this has occurred in a generation--a raw exploration of new worlds unparalleled since NASA's Voyager missions to Uranus and Neptune--and nothing like it is planned to happen ever again. The photos that New Horizons sent back to Earth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think our most historic achievements are in the past, the most distant planetary exploration ever attempted not only succeeded but made history and captured the world's imagination.How did this happen? Chasing New Horizons is the story of the men and women behind the mission: of their decades-long commitment; of the political fights within and outside of NASA; of the sheer human ingenuity it took to design, build, and fly the mission; and of the plans for New Horizons' next encounter, 1 billion miles past Pluto. Told from the insider's perspective of Dr. Alan Stern--the man who led the mission--Chasing New Horizons is a riveting story of scientific discovery, and of how far humanity can go when people focused on a dream work together toward their incredible goal.

    Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves. By some estimates, roughly one in four Americans might be considered addicts. On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction. So what is the difference between drug use, abuse, and clinical addiction? What causes addictions? What happens when your brain is on drugs, and why do addicts behave the way they do?12 Lectures 1.

    Feynman's contributions to twentieth-century physics, but few realize how engaged he was with the world around him -- how deeply and thoughtfully he considered the religious, political, and social issues of his day. Now, a wonderful book -- based on a previously unpublished, three-part public lecture he gave at the University of Washington in 1963 -- shows us this other side of Feynman, as he expounds on the inherent conflict between science and religion, people's distrust of politicians, and our universal fascination with flying saucers, faith healing, and mental telepathy. Here we see Feynman in top form: nearly bursting into a Navajo war chant, then pressing for an overhaul of the English language (if you want to know why Johnny can't read, just look at the spelling of "friend"); and, finally, ruminating on the death of his first wife from tuberculosis. This is quintessential Feynman -- reflective, amusing, and ever enlightening.

    While many of us are taught that anonymous social, political, and economic forces are the driving factors behind events of the past, acclaimed historian and award-winning Professor J.

    Jo Marchant's book can begin to heal it. For at least 20,000 years, we have led not just an earthly existence but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are--our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.Our relationship to the stars and planets has moved from one of awe, wonder and superstition to one where technology is king--the cosmos is now explored through data on our screens, not by the naked eye observing the natural world. Indeed, in most countries modern light pollution obscures much of the night sky from view. Jo Marchant's spellbinding parade of the ways different cultures celebrated the majesty and mysteries of the night sky is a journey to the most awe inspiring view you can ever see--looking up on a clear dark night. That experience and the thoughts it has engendered have radically shaped human civilization across millennia. The cosmos is the source of our greatest creativity in art, in science, in life.To show us how, Jo Marchant takes us to the Hall of the Bulls in the caves at Lascaux in France, and to the summer solstice at a 5,000-year-old tomb at New Grange in England. We discover Chumash cosmology and visit medieval monks grappling with the nature of time and Tahitian sailors navigating by the stars. We discover how light reveals the chemical composition of the sun, and we are with Einstein as he works out that space and time are one and the same. A four-billion-year-old meteor inspires a search for extraterrestrial life. The cosmically liberating, summary revelation is that star-gazing made us human.

In doing so, you'll learn how cutting-edge advancements in science and technology are applied to investigations and how to evaluate evidence and think like a forensic scientist. Using her extensive background in the field and her skill at weaving riveting stories, Professor Murray invites you peer over the shoulders of investigators as they examine some of the most famous crimes in history, as well as cases that shed light on what happens when the justice system goes awry. Whether they're controversial or by-the-book, solved or unsolved, hot or cold, these cases are an opportunity to gain deeper insight into the historic and cutting-edge methods and tools forensic scientists use on the job. Having participated in hundreds of investigations in America and abroad, Professor Murray intersperses these historical examinations with some of her own, equally intriguing, personal experiences.Please note there is a 293 page book included in this course so please do not Notabook again.

    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

    

    (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.
