November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.

    In their new book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about the mysteries of the universe, in nontechnical language marked by both brilliance and simplicity. In The Grand Design they explain that according to quantum theory, the cosmos does not have just a single existence or history, but rather that every possible history of the universe exists simultaneously. When applied to the universe as a whole, this idea calls into question the very notion of cause and effect. But the “top-down” approach to cosmology that Hawking and Mlodinow describe would say that the fact that the past takes no definite form means that we create history by observing it, rather than that history creates us. The authors further explain that we ourselves are the product of quantum fluctuations in the very early universe, and show how quantum theory predicts the “multiverse”—the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature.Along the way Hawking and Mlodinow question the conventional concept of reality, posing a “model-dependent” theory of reality as the best we can hope to find. And they conclude with a riveting assessment of M-theory, an explanation of the laws governing us and our universe that is currently the only viable candidate for a complete “theory of everything.” If confirmed, they write, it will be the unified theory that Einstein was looking for, and the ultimate triumph of human reason.A succinct, startling, and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform—and provoke—like no other.'

    The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

    

    In A Generation of Sociopaths, Gibney examines the disastrous policies of the most powerful generation in modern history, showing how the Boomers ruthlessly enriched themselves at the expense of future generations.Acting without empathy, prudence, or respect for facts--acting, in other words, as sociopaths--the Boomers turned American dynamism into stagnation, inequality, and bipartisan fiasco. The Boomers have set a time bomb for the 2030s, when damage to Social Security, public finances, and the environment will become catastrophic and possibly irreversible--and when, not coincidentally, Boomers will be dying off. Gibney argues that younger generations have a fleeting window to hold the Boomers accountable and begin restoring America.

    A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with nature’s most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.At the end of the seventeenth century—an age of religious wars, plague, and the Great Fire of London—when most people saw the world as falling apart, these earliest scientists saw a world of perfect order. They declared that, chaotic as it looked, the universe was in fact as intricate and perfectly regulated as a clock. This was the tail end of Shakespeare’s century, when the natural land the supernatural still twined around each other. Disease was a punishment ordained by God, astronomy had not yet broken free from astrology, and the sky was filled with omens. It was a time when little was known and everything was new. These brilliant, ambitious, curious men believed in angels, alchemy, and the devil, and they also believed that the universe followed precise, mathematical laws—-a contradiction that tormented them and changed the course of history.The Clockwork Universe is the fascinating and compelling story of the bewildered geniuses of the Royal Society, the men who made the modern world.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

Among the books of the Old Testament, you’ll explore:• Genesis: Uncover fascinating features of the Old Testament’s opening, such as how the events of the first week of creation form an elaborate pattern, expressing the complex order of the universe; and how the text does not lay primary blame for “the fall” on the woman, Eve;• Deuteronomistic History: Study the epic history of the people of Israel in the Promised Land; follow the story of the Israelites’ disobedience to God, and its tragic consequences; • The Prophets: Through the dramatic stories of the prophets, take account of the challenges faced by those who sought to actualize God’s plan for humanity; • The Books of Ruth and Esther: Among notable women in the Old Testament, explore two stories of women who are doubly at risk, and who prevail through loyalty, resourcefulness, and integrity; and• Daniel and the Apocalyptic: In the Book of Daniel, encounter the genre of apocalyptic literature - revelation initiated by God - and contemplate the figure of “the Son of Man,” a promised redeemer.Throughout the lectures, Professor Miller offers a wealth of perspectives on how to approach the texts. You’ll assess the role of translation in the understanding of the texts, studying the meanings of key Hebrew words; you’ll also look in depth at the history, dating, and writing of the texts, and you’ll study their literary and linguistic features, noting how they achieve their impact on the reader.In Understanding the Old Testament, you’ll take a revelatory look at this epically impactful document, finding its deeper historical and religious meanings, as well as its sublime literary treasures.

    Almost daily, researchers are recovering lost information that corrects our picture of what had been a misunderstood era. As a result, we know more than ever about the roles women played in medieval life.       What did it mean to be a heroine in the medieval world? As the four subjects of this course make clear, it meant shaping and changing that world. In the monasteries and churches where people prayed, the universities where they wrote and thought, and even on the political map of Europe itself, these women made differences perceived not only in our time, but in theirs. Women of Intellect, Words, and Passion        These lectures are an extraordinary opportunity to study great women of the past in their own words. Professor Wheeler bases her discussions on recently discovered or recovered written records they left behind, from Hildegard's prodigious scholarship to the personal letters of Heloise and detailed transcripts of Joan of Arc's trial.       With these documents as a basis, you will see Heloise (1101-1163) as a forerunner of Europe's new day. Her letters passionately overflow with the new knowledge of her day. With her star-crossed love, Abelard, she invented a new mode of philosophic thought.       Only now are scholars recovering the long, important second half of the story of Heloise as a woman of power after Abelard's death. Her letters show her to be well versed on such topics as Cicero, classical philosophy, Latin poetry, and rhetoric.       She saw the institution of marriage in her day as little more than a commercial transaction, and its duties burdensome, noisy, costly, and dirty. Her letters reveal her desire to be Abelard's "meretrix" (prostitute) rather than his "imperatrix" (empress). In her discussions on Heloise, Professor Wheeler also covers the long debate as to whether Abelard and Heloise's letters to one anotherthe first, first-person record of a love affair in human history are genuine or not.       Hildegard of Bingen, like Heloise a 12th-century abbess, is revealed as the last flowering of antique learning. She lived a dramatic life as a mystic, voluminous writer, and preacher. She was a personal advisor to Emperor Frederick Barbarossa, and her political involvement and passion as an advocate for clerical and imperial reform give her special interest in our day.       Only in the last generation have scholars rediscovered this amazing medieval intellect. Based on her letters, at least four popes and 10 archbishops corresponded with her, not to mention some 100 other individuals notable to history.Among her many writings, her Book of Simple Medicine was an impressive mini-encyclopedia on what we today would call the natural sciences.       But Hildegard is also known as the "holy hypochondriac," subject to disabling migraines. Were her visions delusions, a result of brainstorms caused by chemical imbalances? Women of Action and Legend        Eleanor of Aquitaine (1124-1204), Queen of France and then England, mother of at least 10 children, scandalized her contemporaries and has fascinated us ever since. She accompanied her husband, Louis VII, on the second Crusade, and her exploits are a reminder that women were crusaders not merely camp followers in numbers that rivaled those of men.       You will learnbased on as-yet-unpublished research by Professor Andrew Lewis that Eleanor was probably born in 1124, not 1122 as normally thought. As a physically hearty woman of courage, she provides a way for historians to explore the diverse roles that women played in enabling or resisting the Crusades. This is exciting work that will allow us to understand medieval women outside the context of home and family as agents of sometimes-radical change.       Eleanor's life is so amazing that it is easy to see why she has become the staple of legends. Among those you will consider are whether she passionately adored, then fought endlessly with, her second husband, Henry II of England (all too true); whether she poisoned Henry's mistress, Rosamund (no proof); and whether she held "courts of love" to encourage and engage in amatory liaisons (again, unproven).       Joan of Arc (1412-1431) was the illiterate French peasant girl whom Mark Twain described as the "youngest person of either sex to lead her nation's army before the age of 19." Known as La Pucelle " (the "maid" or "virgin"), she lacked any kind of military training, yet her military instincts seemed impeccable. Although she carried a sword in battle, she never used it to kill a man, and seems never to have become used to the sight of dead or dying men.Was this young woman who heard heavenly voices an incomprehensible quirk, or did she change the course of European and world history? Ironically, this debate is complicated by the detailed transcripts of her trials, which make her one of the best-documented figures of pre-modern times.       Trial records and her letters reveal her as someone who spoke with "compelling simplicity, quick wit, and piercing honesty." This girl spoke terribly well," said Albert d'Ourches. "I would really like to have had so fine a daughter."       Professor Wheeler dismisses as myth the notions that Joan was actually of noble birth, or that she never fully developed physically as a woman. These lectures reveal Joan as perhaps most memorable for what she was not: a queen, a mother, a beauty, or an intellectual. Instead, she was a woman of action, and the kind of person who is often an enigma to modern intellectuals: someone of profound religious faith.       Appreciating how these four heroines have been understood and misunderstood will help you understand how history passes judgment on both women and the Middle Ages. The contemporary research upon which this course is based can move us beyond how women "ought" to have been to better knowledge, however precarious, about how women were. 24 Lectures 1.

    Thomas Madden is a professor of medieval history at Saint Louis University.As late as 1518, plans were laid by Pope Leo X and the monarchs of Europe to set aside their internal quarrels and once more embark on a holy crusade to wrest the Middle East from the Ottoman Turks. Finding accord and even enthusiasm for the enterprise, all was on course for a multiyear military campaign to push east from North Africa through Egypt and south through the Balkans to squeeze the Turks in a pincer movement and finally oust the Muslims from the Holy Land. The great plan, however, died when Europe was once again plunged into internal strife with the death of Holy Roman Emperor Maximilian I, who had been a leader for the crusade.Even this event in conjunction with the beginnings of the Protestant Reformation, the rise of ever-stronger Ottoman leaders, and the political conflicts throughout Europe did not completely erase the idea of crusading. Today, the military orders of the Teutonic Knights and the Knights Hospitallers continue to care for the poor and the sick, albeit without raising armies to fight.For over 400 years, crusaders (“those signed by the cross”), out of Christian zeal, a declared love for their fellow man, and, in many cases, a simple desire for fortune, glory, and heavenly reward, marched to the Holy Land to battle both a real and perceived threat to their way of life and their religious beliefs. The story of the many crusades are filled with an unremitting passion to keep or return the home of Christianity to Christians. It is also filled with death, destruction, disorder, greed, avarice, and self-interest on all sides. Much of what occurred during the Crusades has come down to us today in the form of continued suspicion among religious ideologies—not only between Christians and Muslims, but also internally among Christian sects and, to some degree, among Muslim sects. There is certainly much to learn about our own history from a better understanding of the Crusades and what led so many to crusade.
