    In the hands of one of today’s hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself, a period modern cosmology of which Einstein never dreamed. Increasingly, though, physicists are going out into realms that make the theory of relativity seem like child’s play. Carroll’s scenario is not only elegant, it’s laid out in the same easy-to- understand language that has made his group blog, Cosmic Variance, the most popular physics blog on the Net. From Eternity to Here uses ideas at the cutting edge of theoretical physics to explore how properties of spacetime before the Big Bang can explain the flow of time we experience in our everyday lives. Carroll suggests that we live in a baby universe, part of a large family of universes in which many of our siblings experience an arrow of time running in the opposite direction. It’s an ambitious, fascinating picture of the universe on an ultra-large scale, one that will captivate fans of popular physics blockbusters like Elegant Universe and A Brief History of Time.

    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?

    Indeed, without religion, our lives are left without meaning and are likely to degenerate into moral chaos. In this Very Short Introduction, philosopher Stephen Law explains why these claims are false and why humanism--though a rejection of religion--nevertheless provides both a moral basis and a meaning for our lives. Indeed, Law shows that humanism is a quite positive alternative to religion. The humanist is not simply one who denies the truth of religious belief, but one who believes we can enjoy meaningful, purposeful, and good lives without religion. And far from embracing moral nihilism, humanists are often deeply committed people, to be found at the forefront of many important ethical campaigns. Law goes on to show how the term humanism is used in a variety of ways. Marx described himself as a humanist but the Pope has also expressed support for what he calls humanism. Law argues for humanism as it is most commonly understood--as a positive, moral form of atheism.

    Someday, we know, we will all die. And, we know, so too will the universe itself.Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed.Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning.Let us embark.

    But how much do we really know about its origins? Who were the people who actually wrote the sacred texts that became part of the Christian Bible? The New Testament: A Very Short Introduction authoritatively addresses these questions, offering a fresh perspective on the underpinnings of this profoundly influential collection of writings. In this concise, engaging book, noted New Testament scholar Luke Timothy Johnson takes readers on a journey back to the time of the early Roman Empire, when the New Testament was written in ordinary Greek (koine) by the first Christians. The author explains how the Gospels, Acts of the Apostles, and Revelation evolved into the canon of sacred writings for the Christian religion, and how they reflect a reinterpretation of the symbolic world and societal forces of first-century Greco-Roman and Jewish life. Equally important, readers will find both a positive and critical reading of the New Testament--one that looks beyond its theological orientation to reveal an often-surprising diversity of viewpoints. This one-of-a-kind introduction engages four distinct dimensions of the earliest Christian writings--anthropological, historical, religious, and literary--to provide readers with a broad conceptual and factual framework. In addition, the book takes an in-depth look at compositions that have proven to be particularly relevant over the centuries, including Paul's letters to the Corinthians and Romans and the Gospels of John, Mark, Matthew, and Luke. Ideal for general readers and students alike, this fascinating resource characterizes the writing of the New Testament not as an unknowable abstraction or the product of divine intervention, but as an act of human creativity by people whose real experiences, convictions, and narratives shaped modern Christianity.

    Yet Vikings were also traders, settlers, and farmers, with a complex artistic and linguistic culture, whose expansion overseas led them to cross the Atlantic for the first time in European history. Highlighting the latest archaeological evidence, Julian Richards reveals the whole Viking world: their history, their culture, and their legacy of overseas expansion for trade, colonization, and plunder. Viking identity is explored through what we have learned about their towns, art, shipbuilding, and religious rituals. Here the Viking story is brought up to the present, from the tales of adventure found in medieval Icelandic sagas, to their exploitation as a symbol of nationalism in the nineteenth century by Wagner, and later by Hitler and the Nazi party. The author also highlights their impact and influence on the history and people of Northern Europe. Vikings, a fascinating new look at a people and culture that have been reinvented throughout history, will take readers closer to discovering who they really were.

    Fifty years ago, a few Americans became the first to do the reverse--and shared with Earth-bound audiences the view of their own planet hanging in the sky instead.Recently, the connection has been discovered to be even closer: a fragment of the Earth's surface was found embedded in a rock brought back from the Moon. And astronauts are preparing to return to the surface of the Moon after a half-century hiatus--this time to the dark side.Oliver Morton explores how the ways we have looked at the Moon have shaped our perceptions of the Earth: from the controversies of early astronomers such as van Eyck and Galileo, to the Cold War space race, to the potential use of the Moon as a stepping stone for further space exploration.Advanced technologies, new ambitions, and old dreams mean that men, women, and robots now seem certain to return to the Moon. For some, it is a future on which humankind has turned its back for too long. For others, an adventure yet to begin.

    Featuring fascinating insights into our scientific future born from the author’s provocative conversations with Nate Silver, David Chang, and Scott Derrickson, Knocking on Heaven’s Door is eminently readable, one of the most important popular science books of this or any year.

    Using examples from Byzantinearchitecture, art and literature, Sarris shows how their legacy was re-worked and re-invented in the centuries ahead, in the face of external challenges and threats. Charting the impact of warfare with the Persian and Islamic worlds to the east, Sarris explores the creativity of Byzantine statecraftand strategy, as well as the empire's repeated (but ultimately forlorn) attempts to enlist aid from the Christian powers of Western Europe to ensure its survival.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.
