From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

These simple statements hold huge implications about how the universe must operate if it was truly infinite rather than finite, as is commonly thought. In one sense, this book, Universal Cycle Theory, may seem radical because it postulates that the universe operates in ways that are dramatically different from what we are taught. Yet, this new theory is conventional in the sense that it closely conforms to virtually all existing laws, equations, and observations. There are only two elements that make the Universal Cycle Theory radical cycles and infinity. Other than that, much of what you read in this book will seem familiar and conventional. Cycles are crucial because they are reflections of how matter behaves in an infinite universe: as vortices and waves. A vortex forms when matter rotates, producing circular cycles. A wave forms when colliding matter compresses and decompresses, producing linear cycles. Infinity is crucial because it explains the extent and structure of the universe. We assume that matter is infinitely divisible in the microscopic direction and infinitely integrable in the macroscopic direction. We assume that time was infinite in the past and will be infinite in the future. This concept of infinity is unique, having never been employed in a model of the universe before. It resolves many of the paradoxes and contradictions currently riddling physics and cosmology.

Contributions by three authors treat aspects of noncommutative geometry that are related to cyclic homology. The authors give rather complete accounts of cyclic theory from different points of view. The connections between (bivariant) K-theory and cyclic theory via generalized Chern-characters are discussed in detail. Cyclic theory is the natural setting for a variety of general abstract index theorems. A survey of such index theorems is given and the concepts and ideas involved in these theorems are explained.

The theory of algebraic function fields over finite fields has its origins in number theory. However, after Goppa`s discovery of algebraic geometry codes around 1980, many applications of function fields were found in different areas of mathematics and information theory. This book presents survey articles on some of these new developments. The topics focus on material which has not yet been presented in other books or survey articles.

In the last twenty years, cosmology has unexpectedly emerged as one of the most exciting and dynamic fields of modern science. From astoundingly precise measurements of the cosmic microwave background to the ongoing mysteries of dark energy and dark matter, modern cosmology is unquestionably in the midst of its Golden Age. And yet, one of the most eminent mathematical physicists of our age, Roger Penrose is convinced that there is one fundamental problem that is consistently being overlooked: why did our universe begin in such a particular state of extremely low entropy? His Conformal Cyclic Cosmology (CCC) is an attempt to directly address that question. This extensive conversation between Howard Burton and Roger Penrose, co-recipient of the 2020 Nobel Prize in Physics and Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute at the University of Oxford, explores his motivation to come up with this theory in the first place and provides detailed insights into his groundbreaking research. This carefully-edited book includes an introduction, A Hidden Audience, and questions for discussion at the end of each chapter: I. Inadvertent Success - An inside look at a mysterious publishing phenomenon II. Considering Entropy - Minimum, maximum and both at the same time III. Mysteries and False Explanations - Dark issues and inflationary hyperbole IV. Conformal Geometry - Reinterpreting the end and the beginning V. CCC: The Basic Idea - Matching beginnings and ends, conformally VI. Light Cones - Photons vs. massive particles VII. Massive Headaches - And how we might make them disappear VIII. Necessary Conditions - Dark energy, dark matter and information loss in black holes IX. Cosmic Imprints? - Searching for evidence of past aeons X. Battling Onwards - Challenges of an irrepressibly independent thinker About Ideas Roadshow Conversations Series: This book is part of an expanding series of 100+ Ideas Roadshow conversations, each one presenting a wealth of candid insights from a leading expert through a focused yet informal setting to give non-specialists a uniquely accessible window into frontline research and scholarship that wouldn't otherwise be encountered through standard lectures and textbooks.

This book is a comprehensive study of cyclic homology theory together with its relationship with Hochschild homology, de Rham cohomology, S1 equivariant homology, the Chern character, Lie algebra homology, algebraic K-theory and non-commutative differential geometry. Though conceived as a basic reference on the subject, many parts of this book are accessible to graduate students.

This book presents new data and additional questions regarding the linguistic cycle. The topics discussed are the pronoun, negative, negative existential, analytic-synthetic, distributive, determiner, degree, and future/modal cycles. The papers raise questions about the length of time that cycles take, the interactions between different cycles, the typical stages and their stability, and the areal factors influencing cycles. The languages and language families that are considered in depth are Central Pomo, Cherokee, Chinese, English, French, Gbe, German, Hmong-Mien, Maipurean, Mayan, Mohawk, Mon-Khmer, Niger-Congo, Nupod, Quechuan, Sino-Tibetan, Tai-Kadai , Tuscarora, Ute, and Yoruboid. One paper covers several of the world’s language families. Cyclical change connects linguists working in various frameworks because it is exciting to find a reason behind this fascinating phenomenon.
