Emma Maria Rossini appears to be the luckiest girl in the world. She's the daughter of a beautiful and loving mother, and her father is one of the most famous film actors of his generation. She's also the granddaughter of a rather eccentric and obscure Italian astrophysicist. But as her seemingly charmed life begins to unravel, and Emma experiences love and tragedy, she ultimately finds solace in her once-derided grandfather's Theorem on the universe. The Space Between Time is humorous and poignant and offers the metaphor that we are all connected, even to those we have loved and not quite lost.
In principle, the elements of space and time cannot be measured. Therefore, the following question arises: How are reality and space-time related to each other? In this book, it is argued on the basis of many facts that reality is not embedded but projected onto space and time. We can never make statements about the actual reality outside (basic reality), but we can “only” form pictures of it. These are pictures of the same reality on different levels. From this point of view, the “hard” objects (matter) and the products of the mind are similar in character.
In his introduction to a revolutionary theory of the cosmos, Martin Bojowald shows how the big bang theory may give way to the big bounce theory, which describes our universe as an eternal series of expansions and contractions, with no beginning and no end. In 2000, Bojowald, then a twenty-seven-year-old postdoctoral student at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology, or LQC, was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.
One of TIME’s Ten Best Nonfiction Books of the Decade "Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." --The Sunday Times From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, Helgoland, and Anaximander comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where at the most fundamental level time disappears. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of time.
In new regional history, national states are not seen to play a special role. Regions are understood as evolutionary processes in which time and space—history and geography—are connected in research questions. To illustrate the entanglement of time and space in various forms and ages, this volume explores regional history from around the globe. The editor’s review of the various works written under the heading of regional history serves as an introduction to this theme. This volume shows how historical events and changes have influenced the reproduction of regions in Czechia; it will also highlight how regional identities were manifested in a cultural form in romantic operas of post-Napoleonic Europe. The historically rich West Wits Line gold-mining region in the West Rand of South Africa is also examined within a regional-history framework with the broad theme of ecohealth and well-being. Through case studies, the volume also explores the history of governance and planning in New Zealand’s largest city-region, Auckland, as well as the recent economic history of the State of Mato Grosso in Brazil. Finally, it also brings the idea of regional history to the most personal level of historical consciousness, by examining the experiential shaping of home in the broader meaning of Heimat, as a question of belonging somewhere – both in time and in space.
An invigorating tour of topics that brings together dozens of essays that offer a sweeping account of the author's explorations about science, philosophy, and religion. 34 line illustrations.
Technology Differences over Space and Time looks at how countries use their productive resources—such as workers, skills, equipment and structures, and natural resources. Francesco Caselli develops methods to assess the efficiency with which productive inputs are used, and how these efficiencies vary across countries and over time. Caselli finds that richer countries use skilled workers relatively more efficiently than unskilled workers, and equipment and structures relatively more efficiently than natural resources. They also are relatively more efficient users of labor than of capital. Technological change tends to make countries particularly efficient at using skills and less efficient at using capital. Technical change also favors experienced workers. In order to interpret and understand these findings, Caselli presents a theory of technology choice. In this theory, firms pick technologies that make the most efficient use of the most abundant production factors when these factors are good substitutes for the less abundant factors. Firms pick technologies that make the most of less abundant factors when other suitable factors are not available for substitution. For example, rich countries, where skilled workers are abundant, use skilled workers efficiently, as these are good substitutes for unskilled workers. This flexible framework can be applied to other pairs of inputs, over time, and across countries. Technology Differences over Space and Time has significant implications not only for the theoretical understanding of development and technological innovation, but also for government formulation of industrial policy and multinationals making decisions about what to invest in and where to make those investments.
INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.
Some structural features of languages predict others, some remain unchanged in daughter languages, others have an areal consistency; in establishing typologically, historically and geographically stable features in the worlds languages, examples are included from Kayardild, Djingili, Dyirbal, Mangarayi, Maung, Ngiyambaa.
Rudolf Steiner discovered that, in addition to "ordinary" space, negative space, or "counterspace," also exists, leading to a more holistic worldview. Steiner suggested that it was important to understand counterspace as a necessary supplement to the conventional approach. Science between Space and Counterspace relates the phenomena of our world to both space and counterspace, which leads to a new scientific understanding. If counterspace actually exists, then the resulting interplay between counterspace and "ordinary" space must be significant. This concept is applied to gravity, liquids, gases, heat, light, chemistry, and life. Each aspect involves a separate investigation, whereas the various threads begin to interweave and become a unified whole. A new concept of time, and indications for a new approach to relativity and quantum physics begin to emerge. Note: Science between Space and Counterspace contains advanced mathematical and scientific proofs that the nonspecialist, general reader may find overly difficult.
