    These are today's sins of science—as deplorable as mistaken past ideas about advocating racial purity or using lobotomies as a cure for mental illness. These unwitting errors add up to seven lessons both cautionary and profound, narrated by renowned author and speaker Paul A. Offit. Offit uses these lessons to investigate how we can separate good science from bad, using some of today's most controversial creations—e-cigarettes, GMOs, drug treatments for ADHD—as case studies. For every "Aha!" moment that should have been an "Oh no," this book is an engrossing account of how science has been misused disastrously—and how we can learn to use its power for good.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    The answer to this age-old riddle is universally relevant to our lives.

    Our language even has a word—Machiavellian—that encapsulates the images those responses conjure up: An indistinct figure quietly making his way through the darkest corridors of power, hatching plots to play one rival against another A cold-blooded political liar, ready to justify any duplicity undertaken in the name of a noble end that will ultimately justify the most malignant means A coolly practical leader—amoral at best—willing to do whatever is necessary in a world governed not by ideas of right or wrong, but by solutions dictated by realpolitik.But does the Machiavelli most of us think we know bear any resemblance to the Machiavelli who lived, pondered, and wrote?According to Professor William R. Cook, a reading of Machiavelli that considers only those qualities that we today call "Machiavellian" is incomplete, and Machiavelli himself "certainly would not recognize" such sinister interpretations or caricatures of his writings and beliefs. Indeed, The Prince—on the pages of which so much of this image was built—was not even published in his lifetime.In the 24 lectures that make up Machiavelli in Context, Professor Cook offers the opportunity to meet an extraordinarily thoughtful and sincere student of history and its lessons, and to learn that there is far more to him than can be gleaned from any reading of The Prince, no matter how thorough.Although The Prince is the work by which most of us think we know Machiavelli, and although some have indeed called it the first and most important book of political science ever written, it was not, according to Professor Cook, either Machiavelli's most important work or the one most representative of his beliefs. Those distinctions belong, instead, to his Discourses on the First Ten Books of Livy, a longer work started at about the same time and which would, like The Prince, not be published until well after his death."Everyone who has seriously studied the works of Machiavelli agrees that he ... believed in the superiority of a republican form of government, defined as a mixed constitution with elements of monarchy, aristocracy, and democracy."Once we recover the context of the writing of The Prince, and analyze it along with the Discourses on the First Ten Books of Livy, it will be clear how The Prince can be read as a book designed to guide leaders in the creation—for Machiavelli, restoration—of republican government in Italy."Ultimately, Machiavelli's goal wasn't much different from ours. It was to live in a free and equal participatory society, because he believed that was the greatest way in which human beings could live and flourish."In fact, says Professor Cook, "Machiavelli's republican thought influenced the development of institutions and values both in Europe and in America."To present a complete and well-rounded picture of Machiavelli's ideas on how human societies should be organized and governed, Professor Cook sets aside much of Machiavelli's written output—which included the political work The Art of War, a biography, many letters, and even some plays—to focus on The Prince, the Discourses, and, more briefly, his Florentine Histories.In doing so, Professor Cook draws on the same qualities so evident in his previous courses for The Teaching Company: Tocqueville and the American Experience, Dante's Divine Comedy, Francis of Assisi, and St. Augustine's Confessions.Teaching in the relaxed and informal style of those courses, Professor Cook moves easily among the different disciplines so pertinent to an understanding of Machiavelli's ideas, including history, philosophy, government, and the elements of leadership. He is unfailingly clear, always provides any definitions needed to understand the material at hand, and is always ready with a touch of wit whenever that is appropriate.Because so much of our contemporary misunderstanding of Machiavelli's ideas comes from a lack of context, Professor Cook carefully sets the stage for a complete perspective of Machiavelli's world.Long before he turns to the works themselves, you'll have learned about Florence and its political history, both before and during Machiavelli's lifetime; the developing Renaissance culture of Machiavelli's time, especially as it bears on the use of ancient political thought by writers and political leaders; and Machiavelli's own life story, including his education, service to the Florentine Republic, years spent in exile south of Florence, and the ways each period of his life affected his writings.The result is a thorough grounding in the information one needs to understand and appreciate this stunningly original thinker.You'll learn, for example, what Machiavelli means when he discusses the important ideas of virtù and Fortuna.Though these are today invariably translated as virtue and fortune, Machiavelli's meanings can involve much more. Though he sometimes uses virtù in the sense we would understand today, he often uses the word—which comes from the classical Latin word for Man—as a means of describing the way one practices successful statecraft: aggressively, with no reluctance to use lies, deceit, and cruelty that may be required to maintain power, and hence the stability the people deserve.In a similar way Machiavelli uses Fortuna in a different sense than might have been used by, say, Dante when he describes the vagaries of fate over which we have no control.Instead, Machiavelli uses the adage, "Fortune is like a river." Though we cannot control fortune, which may well choose to make the river flood, a good ruler, practicing virtù, can indeed prepare for it, and thus modify its effects.You'll see how Machiavelli first became exposed to history and one of its earliest great practitioners—the Roman historian, Livy—through his own experience of Fortuna.Though printed books such as Livy's Early History of Rome were too expensive for a family like the young Machiavelli's in the 15th century, his father did own a copy. He had written the index, and a copy of the book had been part of his payment. Thus Machiavelli grew up with the volumes about which he would one day write his own most important work, Discourses on the First Ten Books of Livy.You'll be introduced to Cesare Borgia, the son of Pope Alexander VI and the man regarded as Machiavelli's model for The Prince, especially in the way his actions embodied the virtù so important to Machiavelli.Professor Cook brings this out in a shocking story of Borgia's use of a tough and merciless Spaniard—Ramiro d'Orco—to impose order and stability on the area of north central Italy known as the Romagna that had come under Borgia's rule and was beset by crime and violence.D'Orco's brutal methods had the desired effect. And when the job was completed, the local people emerged from their homes one morning to find the two halves of Ramiro d'Orco's body on opposite sides of the town square of Cesana, because d'Orco had been too tough, and Cesare Borgia needed a way to advertise further his concern for the people whose loyalty he wanted.The story also embodies, for Machiavelli, the idea that cruelty can be "well-used," just as being merciful—withholding such cruelty when a leader deems it needed—may be less than merciful in its long-term impact.Finally, you will get to see, throughout these lectures, the development of Machiavelli's reliance on history for its lessons, his role as a Renaissance Humanist thinker, and the emergence of his republican views, which still have tremendous influence today as we ask how republics start, grow, succeed, or fail.As Professor Cook notes, we are not going to agree with all of Machiavelli's answers. But his commitment to asking the right questions—to thinking, reflecting, and learning everything history has to teach us about the best ways to govern and safeguard the future—was total.

    It lasted 3,000 years, longer than any other on the planet. Its Great Pyramid of Cheops was the tallest building in the world until well into the 19th century and remains the only Ancient Wonder still standing. And it was the most technologically advanced of the ancient civilizations, with the medical knowledge that made Egyptian physicians the most famous in the world.Yet even after deciphering its hieroglyphs, and marveling at its scarabs, mummies, obelisks, and sphinxes, Egyptian civilization remains one of history's most mysterious, as "other" as it is extraordinary. This chronological survey presents the complete history of ancient Egypt's three great Kingdoms: the Old Kingdom, when the pyramids were built and Egypt became a nation under the supreme rule of the pharaoh and the rules of Egyptian art were established; the Middle Kingdom, when Egypt was a nation fighting to restore its greatness; and the New Kingdom, when all the names we know today-Hatshepsut, Tutankhamen, Ramses the Great, Cleopatra, and others-first appeared.Listening Length: 24 hours and 25 minutes

    Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.

    But have you ever wondered how a religion that doesn't even have a god could have accomplished this?Now you have the opportunity to have your questions answered, as this series of 24 lectures by an award-winning teacher traces the history, principles, and evolution of a theology that is both familiar and foreign.You'll learn the astonishing story of Siddhartha Gautama - who was to become the Buddha, or "enlightened one" - the Indian prince who abandoned wife, son, and a privileged life to seek the meaning of life and death, and whose "awakening" and subsequent teachings have since impacted the world as few others have.And you'll learn what happened after his death, as his followers began to share his teachings about the "Four Noble Truths" and the "Path" to Enlightenment. You'll see how Buddhist beliefs underwent significant and even radical change, with different varieties of Buddhism having to take shape as those beliefs spread across India, Central Asia, China, Japan, and virtually every corner of the Western world, such as becoming more respectful of one's duties to family and ancestors in China or becoming reconciled with local deities in Japan.
