And liberated from its mathematical underpinnings, physics suddenly becomes accessible to anyone with the curiosity and imagination to explore its beauty. Science without math? It's not that unusual. For example, we can understand the concept of gravity without solving a single equation. So for all those who may have pondered what makes blueberries blue and strawberries red; for those who have wondered if sound really travels in waves; and why light behaves so differently from any other phenomenon in the universe, it's all a matter of quantum physics. Absolutely Small presents (and demystifies) the world of quantum science like no book before. It explores scientific concepts--from particles of light, to probability, to states of matter, to what makes greenhouse gases bad--in considerable depth, but using examples from the everyday world. Challenging without being intimidating, accessible but not condescending, Absolutely Small develops the reader's intuition for the very nature of things at their most basic and intriguing levels.

    By replacing equations with diagrams, the book allows non-specialist readers to fully understand the concepts in relativity without the slow, painful progress so often associated with a complicated scientific subject. It allows readers not only to know how relativity works, but also to intuitively understand it.

    It is the basis of our understanding of atoms, radiation, and so much else, from elementary particles and basic forces to the behaviour of materials. But for a century it has also been the problem child of science, plagued by intense disagreements between its intellectual giants, from Albert Einstein to Stephen Hawking, over the strange paradoxes and implications that seem like the stuff of fantasy. Whether it's Schr�dinger's cat--a creature that is simultaneously dead and alive--or a belief that the world does not exist independently of our observations of it, quantum theory is what challenges our fundamental assumptions about our reality. In Einstein's Unfinished Revolution, globally renowned theoretical physicist Lee Smolin provocatively argues that the problems which have bedeviled quantum physics since its inception are unsolved for the simple reason that the theory is incomplete. There is more, waiting to be discovered. Our task--if we are to have simple answers to our simple questions about the universe we live in--must be to go beyond it to a description of the world on an atomic scale that makes sense. In this vibrant and accessible book, Smolin takes us on a journey through the basics of quantum physics, introducing the stories of the experiments and figures that have transformed the field, before wrestling with the puzzles and conundrums that they present. Along the way, he illuminates the existing theories about the quantum world that might solve these problems, guiding us toward his own vision that embraces common sense realism. If we are to have any hope of completing the revolution that Einstein began nearly a century ago, we must go beyond quantum mechanics as we know it to find a theory that will give us a complete description of nature. In Einstein's Unfinished Revolution, Lee Smolin brings us a step closer to resolving one of the greatest scientific controversies of our age.

    Jim Carter, the Einstein of outsiders, has developed his own complete theory of matter and energy and gravity that he demonstrates with experiments in his backyard,-with garbage cans and a disco fog machine he makes smoke rings to test his ideas about atoms. Captivated by the imaginative power of his theories and his resolutely DIY attitude, Wertheim has been following Carter's progress for the past decade.Centuries ago, natural philosophers puzzled out the laws of nature using the tools of observation and experimentation. Today, theoretical physics has become mathematically inscrutable, accessible only to an elite few. In rejecting this abstraction, outsider theorists insist that nature speaks a language we can all understand. Through a profoundly human profile of Jim Carter, Wertheim's exploration of the bizarre world of fringe physics challenges our conception of what science is, how it works, and who it is for.

    Their quest: to be the first to detect gravitational waves, infinitesimal quakes that stretch and compress space-time and could add a brand-new dimension to our universal knowledge-allowing us to hear a sun going supernova, black holes colliding, and perhaps one day, the remnant rumble of the Big Bang itself...

    In the late 1920s, astronomers defeated this assumption with a startling new discovery. From Earth, the light of distant galaxies appeared to be red, meaning that those galaxies were receding from us. This led to the revolutionary realization that the universe is expanding. The Red Limit is the tale of this discovery, its ramifications, and the passionately competitive astronomers who charted the past, present, and future of the cosmos.

    

    You'll discover how the sun shines, why light is both a wave and a particle, the certainty of the Uncertainty Principle, Schrodinger's Cat, Einstein's spooky action, how to build a quantum computer, and why quantum mechanics drives even its experts completely crazy.

    Professor Weil introduces you to masterpieces such as Tolstoy's War and Peace, Dostoevsky's Crime and Punishment, Pushkin's Eugene Onegin, Gogol's Dead Souls, Chekhov's The Seagull, Pasternak's Doctor Zhivago, and many other great novels, stories, plays, and poems. In all, you plunge into more than 40 works by a dozen writers, from Aleksandr Pushkin in the 19th century to Aleksandr Solzhenitsyn in the 20th century. You also investigate the origin of Russian literature itself, which traces its lineage back to powerful epic poetry and beautiful renderings of the Bible into Slavic during the Middle Ages. All of these works are treated in translation, but Professor Weil does something very unusual in the literature-in-translation arena. For almost every passage that he quotes in English, he reads an extract in the original Russian, with a fluent accent and an actor's sense of drama.

    Robinson Crusoe. Harry Potter. What do these memorable characters have in common? Why do we turn to certain stories again and again? And what impact have they made on world history? These 24 eye-opening lectures give fresh insight into some of the greatest heroes in world literature, from warriors such as Beowulf and Odysseus to unexpected heroes such as Uncle Tom and Sancho Panza.Professor Shippey gives you an inside glimpse into the writer's process. Learn how authors "write into the gap" to flesh out-or, in some cases, reimagine altogether-old stories, making them new for new readerships with different values. By examining what makes these heroes such compelling characters, you'll see how they provide a window to better understand ourselves.From the beginnings of world literature through today's bestsellers, look at what makes characters successful-and how they reflect our changing cultural mores. For instance, after the horrors of global war in the 20th century, the world was waiting for a hero like Frodo Baggins, J.R.R. Tolkien's meek hobbit hero, someone called to duty rather than born strong and fearless.You'll also examine ways that great heroes have changed the course of history, defining nations and redefining our sense of self and our relationships. From the mythical journey of Aeneas to Jane Austen's country dances, you'll survey a wealth of memorable stories and consider why such heroes were necessary-and how they continue to influence our lives today.

    But there is a method for avoiding such pitfalls of human nature, and it's called skepticism. By using rational inquiry and seeing subjects from a scientific perspective, we can approach even the most sensitive claims with clear eyes to ultimately arrive at the truth. During 18 lectures that will surprise, challenge, and entertain you, you will learn how to think, not just what to think-and you'll come to understand why extraordinary claims require extraordinary evidence.You'll discover how skepticism can help differentiate between real science and pseudoscience, as well as between "scientific" history and pseudohistory-distinctions that have serious educational and political implications.Fascinating case studies illustrate how you can apply the methods of skepticism to detect specious claims and faulty logic in any scenario you encounter such as:•The methodology employed by Holocaust deniers•Arguments made by proponents of creationism•The biology of near-death experiences and the sensed-presence effect•Psychic abilities and other "paranormal" phenomena.As you learn how our brains work to form beliefs, you'll examine the classic fallacies of thought that lead us to experience mistakes in thinking and to form bad arguments in favor of our beliefs.Is there a God? Is there life after death? Is there a basis for morality without God? Skepticism 101 doesn't shy away from controversial questions, nor does it give final answers. What it offers are methods and hard evidence for rationally evaluating various claims and positions, and an opportunity to understand why you believe what you believe.Listening Length: 9 hours and 10 minutes

    Consider the following:Although Judaism is defined by its worship of one God, it was not always a pure monotheism. In I Kings 8, King Solomon addresses the Lord by saying, "There is no God like You," suggesting that the Israelites recognized the existence of other gods.The practice of Judaism was focused on animal sacrifice until the destruction of the Second Temple by the Romans in the 1st century, which forced a radically new approach to worship.The political emancipation of the Jews in 18th-century Europe transformed a 1,000-year-old style of Jewish life. "You can’t find an expression of Judaism today that is just like [the way] Jews lived 300 years ago," says Professor Shai Cherry.Yet for all it has changed, Judaism has maintained unbroken ties to a foundation text, an ethnicity, a set of rituals and holidays, and a land.A Journey of Religious DiscoveryIn these 24 lectures, Professor Cherry explores the rich religious heritage of Judaism from biblical times to today.He introduces you to the written Torah, and you learn about the oral Torah, called the Mishnah (which was also later written down), and its commentary, the Gemara. And you discover how the Mishnah and Gemara comprise the Talmud, and how they differ from another form of commentary called Midrash.He teaches you about the three pillars of the world defined more than 2,000 years ago by Shimon the Righteous: Torah, worship, and deeds of loving kindness.He takes you through the calendar of Jewish holidays, from the most important, the Sabbath, to the key holidays of Rosh Hashanah, Yom Kippur, Passover, and Pentecost (Shavuot); and to historically minor celebrations such as Channukah, which is now a more visible holiday.You also learn about the origins and attributes of the different Jewish movements that formed in the wake of Emancipation in the late 1700s and the resulting full emergence of Judaism into Western society. These include the Reform, Conservative, Modern Orthodox, and Reconstructionist movements."Although Jewish history is not one long tale of travails," says Professor Cherry, "there have been several catastrophes that powerfully shaped the Jewish consciousness." He includes discussions of the impact on Jewish thought of the Babylonian exile and the destruction of the Second Temple in antiquity, and the Holocaust in the 20th century."We will see that for every topic that we cover we have a multiplicity of responses and a multiplicity of answers," says Professor Cherry, noting that this course could just as easily be called "An Introduction to Judaisms."What’s in a Name?Judaism’s sacred text is the Bible, also called the TaNaKH, the Torah, the Hebrew Bible, and, by Christians, the Old Testament. As Professor Cherry points out, these terms have different implications:TaNaKH: This is the Hebrew acronym for the three sections of the Bible—the Torah (the first five books, known as the Pentateuch), Nevi’im (Prophets), and Ketuvim (Writings).Torah: The word torah means "a teaching," and it can refer to the Pentateuch, the entire TaNaKH, or even the whole corpus of Jewish thought.Hebrew Bible: This is a religiously neutral term used by scholars for the TaNaKH. Professor Cherry notes that his expertise is in the TaNaKH, not the Hebrew Bible, since he approaches the text from the Jewish interpretive tradition.Old Testament: Christians refer to the TaNaKH as the Old Testament, since in their eyes it has been superseded by the New Testament. For Catholics, the Old Testament has a number of books that are not included in the TaNaKH.Interpreting the ScripturesJews and Christians not only have different names for the Bible, they understand it very differently. For example, Christianity takes an episode that is relatively minor in Jewish tradition—the temptation of Adam and Eve—and extracts from it the doctrine of original sin.Similarly, early rabbis took the repeated phrase, "And there was evening and there was morning," in the enumeration of the six days of creation and concluded that the day begins in the evening, which is why Jews start the celebration of their holidays at sundown.As a case study in interpretation, Professor Cherry delves deeply into the prohibition against seething (boiling) a kid in its mother’s milk, mentioned in Exodus and Deuteronomy, which led to the kosher practice of strict separation of meat and milk products. Recently, a scholar pointed out that the original Hebrew could be interpreted to mean fat instead of milk.A prohibition against seething a kid in its mother’s fat makes more sense, because it is another way of saying that the mother and offspring should not be slaughtered on the same day, in accord with the biblical injunction against killing two generations of the same species on the same day.But the rabbis had very good reasons to read the passage as they did, says Professor Cherry, who shows the theological logic that has resulted in the dietary separation of meat and milk, a practice observed by traditional Jews today.Unlocking Mysteries of Jewish Thought and Ritual"Let’s unpack this," Professor Cherry says often during these lectures, as he takes a concept, a biblical passage, or an episode from history and explores its meaning in Jewish thought and ritual.In doing so, he is following the footsteps of the acknowledged master of this form of analysis, the medieval Jewish philosopher Moses Maimonides, who figures prominently throughout the course and is treated in depth in Lecture 14.There, Professor Cherry focuses on Maimonides’s Guide of the Perplexed and its discussion of creation, prayer, and the reasons for the commandments. Maimonides is filled with insights into how Judaism evolved as it did, noting, for example, that the practice of ritual animal sacrifice in early Judaism was God’s way of taking a pagan rite that the Israelites had learned from the Egyptians and redirecting it.In a subsequent lecture, Professor Cherry shows how Maimonides’s success at putting Judaism on a logical footing set the stage for a reaction that produced the Jewish mystical system called the Kabbalah.Professor Cherry unlocks other mysteries, such as why the first day of the seventh month (Tishrei) is the Jewish New Year (Rosh Hashanah). It seems likely, he says, that "this was the time of the Babylonian New Year. So when the Jews were exiled to Babylonia, they saw that the Babylonians celebrated their New Year on that day, and said, ‘We’ve got some sacred occasion where we blow the trumpets, so let’s make that our New Year, too.’"He also explores different concepts of the Messiah, profiling two controversial candidates. The first is Shabbatai Tzvi, who was proclaimed Messiah by followers in 1665, and whose travels across Eastern Europe eventually landed him in Turkey, where he converted to Islam to avoid execution by the authorities.The other candidate is Rebbe Menachem Mendel Scheersohn, a charismatic leader of the Lubavitch Chassidim in Brooklyn, who died in 1994. Rebbe Scheersohn’s widely touted messianic credentials created intense debate and division in the Ultra-Orthodox community.From the Decalogue to Fiddler on the RoofFrom the first lecture on the Torah to the last on the Jews as the Chosen People, this course is packed with fascinating information, including:Jews use the term Decalogue, instead of Ten Commandments because there are actually more than 10 commandments in the Decalogue. For instance, "On six days you shall work and the seventh day shall be a Sabbath to you." Usually that counts as one: that you should have a Sabbath on the seventh day. But there is also, "On six days you shall work."The prophets in the biblical period served the same function as today’s free press. They tell the king what he doesn’t want to hear.When people die in the TaNaKH, everyone goes to the same place, Sheol—a shadowy underworld that is neither heaven nor hell.After crushing the Bar Kochvah revolt of the Jews in the 2nd century, the Romans changed the name of the land of Israel and Judaea to echo the Israelites’ ancient enemies, the Philistines. This is how the region came to be called Palestine.Today, the designation "Temple" on a Jewish house of worship is usually a sign that it is a Reform congregation because Reform Jews no longer look toward the dream of rebuilding the Jerusalem Temple.Orthodox Judaism is just as much a product of modernity as is Reform because several varieties of Orthodoxy emerged in the 19th century as a response to Emancipation, the Enlightenment, and the founding of the Reform movement.In addition, Professor Cherry devotes several lectures to complex issues such as the problem of evil and suffering, the Zionist movement, the place of women in the Jewish world, and how Judaism understands Christianity.Throughout, Professor Cherry is articulate, engaging, and passionate, with a gift for making a point by means of a memorable cultural reference. He calls attention to an echo of Jewish mystic Rav Kook in a Joni Mitchell song; to the Kabbalistic nature of "the force" and "the dark side" in George Lucas’s Star Wars; and to the Sabbath lesson given by Gene Wilder as an Old West rabbi in The Frisco Kid, when he dutifully dismounts his horse at sundown, risking capture by bandits.Professor Cherry notes that when he teaches introductory Judaism at Vanderbilt University, he asks his students to see two films: Fiddler on the Roof, for its picture of the breakdown of tradition as Jews confront modernity; and Woody Allen’s Crimes and Misdemeanors, for its treatment of secular Jews grappling with contemporary issues of faith and ethics. Both films repay viewing in light of the lessons you’ll learn in this course.In his final lecture, Professor Cherry sums up: "The Judaisms we’ve examined in this course reflect the ongoing struggles of the Jewish people from their ancient life as a sovereign nation, to the travails of exile, to the opportunities of acculturation in modernity, and finally to the re-establishment of the state of Israel. Hearing God’s words anew—receiving Torah every day—has meant reinterpreting the tradition, creatively rereading the words of the past, whether they relate to core ideas like the notion of evil and the notion of the Chosen People, or mitzvot such as the prohibition of idolatry, or the laws of marriage and divorce. Even the basis for reinterpreting the tradition, the claim that God’s words do not cease, is itself a rereading of Torah."
