In this volume, 12 eminent scientists and philosophers engage in fundamental, perennial questions about time: Does time exist? Is 'time' a single or multiple entity? Is it possible to reconcile contradictory notions of time, such as subjective and objective, metaphysics and physics, McTaggart's A series and B series, or presentism and eternalism? Does the Special Theory of Relativity dictate a static, deterministic account of reality ('block universe') or does it allow for 'free will'? How did the concept of geologic time originate and what are the limits of its knowledge? How is the Anthropocene defined? Each author examines these questions from the point of view of their own specialties, but without ignoring the metaphysical importance of the issue, nor the possibility that scientific advances might enforce revisions of our brain intuitive judgments.

Time and matter are the most fundamental concepts in physics and in any science-based description of the world around us. Quantum theory has, however, revealed many novel insights into these concepts in non-relativistic, relativistic and cosmological contexts. The implications of these novel perspectives have been realized and, in particular, probed experimentally only recently.In the papers in this proceedings, these issues are discussed in a truly interdisciplinary fashion from philosophical and historical perspectives. The leading contributors, including Nobel laureates T W Hänsch and G t' Hooft, address both experimental and theoretical issues.

Prominent scientists and philosophers of science address contemporary debates on the nature of Time. Their contributions freely discuss its unity and reality, its compatibility with the orders of classical philosophy (present, past and future) and with the disputed idea of free will (Volume 1). They also present a detailed and updated state of the role of Time in the so-called exact sciences: biology — or more precisely genetics, evolution, neurosciences, natural and artificial intelligence (Volume 2) , and physics — relativity, quantum mechanics and quantum gravity, and cosmology (Volume 3).

James Mussell reads nineteenth-century scientific debates in light of recent theoretical discussions of scientific writing to propose a new methodology for understanding the periodical press in terms of its movements in time and space. That there is no disjunction between text and object is already recognized in science studies, Mussell argues; however, this principle should also be extended to our understanding of print culture within its cultural context. He provides historical accounts of scientific controversy, documents references to time and space in the periodical press, and follows magazines and journals as they circulate through society to shed new light on the dissemination and distribution of periodicals, authorship and textual authority, and the role of mediation in material culture. Well-known writers like H. G. Wells and Arthur Conan Doyle are discovered in new contexts, while other authors, publishers, editors, and scientists are discussed for the first time. Mussell is persuasive in showing how his methodology increases our understanding of the process of transformation and translation that underpins the production of print and informs current debates about the status of digital publication and the preservation of archival material in electronic forms. Adding to the book's usefulness are an extended bibliography and a discussion of recent debates regarding digital publication.

Few fields have changed as rapidly as the science of exercise. New research suggests that exercise can increase your life expectancy and stave off cognitive decline more than anything else you do. The best part? You may not need to do as much of it as experts once thought. In this TIME special edition, readers will learn:exactly why exercise is the best anti-ager„and how it changes nearly every part of the bodyeffective ways to squeeze tiny amounts of exercise into your daystrategies for lasting weight loss through exercise in conjunction with the right dietthe best exercises for every goal, whether itÍs stress reduction, better skin, a stronger stomach or a healthier heart

The present volume of Time and Science series is devoted to Physical Sciences and Cosmology. Today more than ever, the question 'is Time an ontological property, a necessary ingredient for the physical description of the world, or a purely epistemological element, relative to our situation in the world?' worry physicists and cosmologists alike. For many of them, Relativity (and particularly General Relativity), as well as its reconciliation with quantum mechanics in the elaboration of a quantum theory of gravitation, points to a negative answer to the first alternative, and leads them to deny the objective reality of time. For others, the answer is nuanced by the evidence of an emerging temporal property when one climbs the scales of the complexity of systems and/or the applicability of the statistical laws of thermodynamics. But for some, the illusion of the unreality of time comes from certain confusions that they denounce, and plead for the re-establishment of time at the heart of physical theories.
