What happened before the primordial fire of the Big Bang: a theory about the ultimate origin of the universe. In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. With quantum uncertainty its fundamental feature, this new picture of cosmic origins introduces the possibility that the origin of the universe was of a quantum nature. Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

When I looked up, I shivered. How many stars were in the sky? A million? A billion? Maybe the number was as big as infinity. I started to feel very, very small. How could I even think about something as big as infinity? Uma can't help feeling small when she peers up at the night sky. She begins to wonder about infinity. Is infinity a number that grows forever? Is it an endless racetrack? Could infinity be in an ice cream cone? Uma soon finds that the ways to think about this big idea may just be . . . infinite.

This is the tale of the many possible lives of Anastasia Valerie Stein which come to touch one another through a twist in the fabric of space-time: Ann, unhappy wife and mother in a world much like our own; Val, independent teacher in a timeline of scarcity; Stacey, a free spirit with two lovers, and Tasha, strangest of all, a professional sorceress in a world where the Third Reich rules England. Together they join to confront a force that manipulates all their worlds, and discover a truth that transcends their individual lives. Finch combines compelling, believable characters, the ancient magic of the Tarot, and quantum physics to weave a spellbinding tale of the infinite possibilities of space and time.

Philosophy, Science, and History: A Guide and Reader is a compact overview of the history and philosophy of science that aims to introduce students to the groundwork of the field, and to stimulate innovative research. The general introduction focuses on scientific theory change, assessment, discovery, and pursuit. Part I of the Reader begins with classic texts in the history of logical empiricism, including Reichenbach’s discovery-justification distinction. With careful reference to Kuhn’s analysis of scientific revolutions, the section provides key texts analyzing the relationship of HOPOS to the history of science, including texts by Santayana, Rudwick, and Shapin and Schaffer. Part II provides texts illuminating central debates in the history of science and its philosophy. These include the history of natural philosophy (Descartes, Newton, Leibniz, Kant, Hume, and du Châtelet in a new translation); induction and the logic of discovery (including the Mill-Whewell debate, Duhem, and Hanson); and catastrophism versus uniformitarianism in natural history (Playfair on Hutton and Lyell; de Buffon, Cuvier, and Darwin). The editor’s introductions to each section provide a broader perspective informed by contemporary research in each area, including related topics. Each introduction furnishes proposals, including thematic bibliographies, for innovative research questions and projects in the classroom and in the field.

In the bestselling tradition of Brene Brown’s Daring Greatly and Nick Vujicic’s Life Without Limits comes a rousing 7-step plan for living a life on fire, filled with hope and possibility—from an inspirational speaker who survived a near-fatal fire at the age of nine and now runs a successful business inspiring people all around the world. When John O’Leary was nine years old, he was almost killed in a devastating house fire. With burns on one hundred percent of his body, O’Leary mustered an almost unimaginable amount of inner strength just to survive the ordeal. The insights he gained through this experience and the heroes who stepped into his life to help him through the journey—his family, the medical staff, and total strangers—changed his life. Now he is committed to living life to the fullest and inspiring others to do the same. An incredible and emotionally honest account of triumph over tragedy, On Fire contains O’Leary’s reflections on being that little boy, the life-giving choices made then, and the resulting lessons he learned. O’Leary very clearly shares that without the right people providing the right guidance, at the right time, he never would have made it through those five months in the hospital, let alone the years that followed as he struggled to regain mobility, embrace his story, and ignite clarity of his life’s purpose. On Fire encourages us to seize the power to choose our path and transform our lives from mundane to extraordinary. Once we stop thinking solely on the big moments in our lives, we can begin to focus on those smaller opportunities that tend to pass us by. These are the events—the inflection points in our lives—that can determine how we feel about life now, where we are headed in the future, and how many lives we can impact along the way. We can’t always choose the path we walk, but we can choose how we walk it. Empowering, inspiring, remarkably honest, and heartfelt, O’Leary’s strength and incredible spirit shine through on every page.
