Why should there be anything at all? Why, in particular, should a material world exist? Bede Rundle advances clear, non-technical answers to these perplexing questions. If, as the theist maintains, God is a being who cannot but exist, his existence explains why there is something rather than nothing. However, this can also be explained on the basis of a weaker claim. Not that there is some particular being that has to be, but simply that there has to be something or other. Rundle proffers arguments for thinking that that is indeed how the question is to be put to rest. Traditionally, the existence of the physical universe is held to depend on God, but the theist faces a major difficulty in making clear how a being outside space and time, as God is customarily conceived to be, could stand in an intelligible relation to the world, whether as its creator or as the author of events within it. Rundle argues that a creator of physical reality is not required, since there is no alternative to its existence. There has to be something, and a physical universe is the only real possibility. He supports this claim by eliminating rival contenders; he dismisses the supernatural, and argues that, while other forms of being, notably the abstract and the mental, are not reducible to the physical, they presuppose its existence. The question whether ultimate explanations can ever be given is forever in the background, and the book concludes with an investigation of this issue and of the possibility that the universe could have existed for an infinite time. Other topics discussed include causality, space, verifiability, essence, existence, necessity, spirit, fine tuning, and laws of Nature. Why There Is Something Rather Than Nothing offers an explanation of fundamental facts of existence in purely philosophical terms, without appeal either to theology or cosmology. It will provoke and intrigue anyone who wonders about these questions.

Durham and Purrington approach the history of the universe by exploring the frontiers of physics, while maintaining a long-standing interest in astronomy and cosmology. They stress that man can not fully understand himself until he understands the universe, of which he is a part.

A thrilling journey through the recent discoveries in astronomy that point to our cosmic significance In The Copernicus Complex, the renowned astrophysicist and author Caleb Scharf takes us on a cosmic adventure like no other, asserting that the age-old Copernican principle is in need of updating. When Copernicus proposed that the Earth was not the fixed point at the center of the known universe (and therefore we are not unique), he set in motion a colossal scientific juggernaut, forever changing our vision of nature. But the principle, Scharf argues, has never been entirely true-we do live at a particular time, in a particular location, under particular circumstances. By bringing together the latest discoveries in cutting-edge astronomy, Scharf shows how many aspects of our cosmic home are genuinely unique, and reveals what it means for our quest to determine whether we are alone in the universe.

This volume collects essays from prominent intellectuals and public figures based on talks given at the 2015 Darwin College Lectures on the theme of 'development'. The writers are world-renowned experts in such diverse fields as architecture, astronomy, biology, climate science, economy, psychology, sports and technology. Development includes contributions from developmental biologist and Nobel laureate John B. Gurdon, Olympic gold medallist Katherine Grainger, astronomer and cosmologist Richard Ellis, developmental psychologist Bruce Hood, former Met Office Chief Scientist Julia Slingo, architect Michael Pawlyn, development economist Ha-Joon Chang and serial entrepreneur Hermann Hauser. While their perspectives and interpretations of development vary widely, their essays are linked by a common desire to describe and understand how things change, usually in the direction of ever-increasing complexity. Written with the lay reader in mind, this interdisciplinary book is a must-read for anybody interested in the mechanisms underlying the changes we see in the world around us.

Galileo, Newton, Herschel, Huggins, Hale, Eddington, Shapley and Hubble: these astronomers applied ideas drawn from physics to astronomy and made dramatic changes to the world-pictures that they inherited. They showed that celestial objects are composed of the same materials as the earth and that they behave in the same way. They displaced successively the earth, the sun and finally the milky way galaxy from being the centre of the universe.
This book contains their biographies and outlines their greatest discoveries. Hard work, physical insight, desire for fame and a strong belief in the rightness of their own ideas were characteristics of all eight. Their often quirky personalities led them into bitter controversies with their contemporaries. But their successes arose from the outstanding clarity of their thoughts, their practical ability and their strong sense of direction in science.

Second edition, completely revised, of the only English translation of Kepler's 1609 masterpiece. A work of astonishing originality, Astronomia Nova stands, with Copernicus's De Revolutionibus and Newton's Principia as one of the founding texts of the scientific revolution. Kepler revolutionized astronomy by insisting that it be based upon physics rather than ideal geometrical models.

The ?eld of cosmology is currently undergoing a revolution driven by d- matic observational progress and by novel theoretical scenarios imported from particle physics. In particular, two most remarkable results were recently - tained from measurements of the angular spectrum of the ?uctuations in the Cosmic Microwave Background (CMB) radiation providing convincing e- dence that the Universe is nearly ?at and from the Hubble diagram of distant supernovae indicating an accelerating expansion rate, which implies the ex- tence of some dark energy as the dominant component of the Universe. Indeed, the next decade will bene't from high quality data on cosmology from diff- ent major experiments and observatories, with a particular important contri- tion from space missions such as WMAP, Planck Surveyor, XMM and SNAP among others. On one side, cosmologists believe they understand the origin of themain ingredients which allowacoherent description of theUniverse from its very earlyphase, namely in?ation, to the actual epoch which accounts for theoriginof theprimordial?uctuations, allowing predictions of their - prints inthe cosmicmicrowave skyandleading to the large scale structure of theUniverse as observed. Ontheother side, theexistence of a non-zero vacuum density is certainly one of the most astonishing results of modern f- damental physics. Understanding its nature andits originwill be one of the major directions of researchinthe following years. In view of the intensive current activity inthe ?eld, aSchoolfully dedicated to these both sides in cosmology was timely

Modern physics has revealed the universe as a much stranger place than we could have imagined. The puzzle at the centre of our knowledge of the universe is time. Michael Lockwood takes the reader on a fascinating journey into the nature of things. He investigates philosophical questions about past, present, and future, our experience of time, and the possibility of time travel. And he provides the most careful, lively, and up-to-date introduction to the physics of time and the structure of the universe.He guides us step by step through relativity theory and quantum physics, introducing and explaining the ground-breaking ideas of Newton and Boltzmann, Einstein and Schroedinger, Penrose and Hawking. We zoom in on the behaviour of molecules and atoms, and pull back to survey the expansion of the universe. We learn about entropy and gravity, black holes and wormholes, about how it all began and where we are all headed. Lockwood's aim is not just to boggle the mind but to lead us towards an understanding of the science and philosophy. Things will never seem the same again after a voyage through The Labyrinth of Time.

Space and time are the most fundamental features of our experience of the world, and yet they are also the most perplexing. Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Is change really possible? Could space and time exist in the absence of any objects or events? Are our space and time unique, or could there be other, parallel worlds with their own space and time? What, in the end, are space and time? Do they really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions, and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. His book is an invitation to think philosophically rather than a sustained argument for particular conclusions, but Le Poidevin does advance and defend a number of controversial views. He argues, for example, that time does not actually flow, that it is possible for space and time to be both finite and yet be without boundaries, and that causation is the key to an understanding of one of the deepest mysteries of time: its direction. Travels in Four Dimensions draws on a variety of vivid examples and stories from science, history, and literature to bring its questions to life. No prior knowledge of philosophy is required to enjoy this book. The universe might seem very different after reading it.

David Harland describes the historical development of particle physics, and explains, in a non-mathematical way, how particle physics has influenced the structure of the Universe from the very beginning of time. He demonstrates the close links between discoveries in particle physics and in cosmology up to the present. He describes how our understanding of the Universe has developed from the discovery that the Universe is expanding, to the idea that all matter originated in a hot, Big Bang, then explains the many subtle improvements to the basic theory that have been necessary to understand how the very smallest particles and earliest structures (the 'microscale') in the Universe evolved to produce the Universe as it is now (the 'macroscale'). The author also describes how scientists are attempting to develop a 'Theory of Everything' that would explain how an instant after the Big Bang a single primordial force was transformed into the four forces of nature that we observe today, which hitherto were believed to be 'fundamental'.

From the bestselling author of The Elegant Universe, Brian Greene's The Fabric of the Cosmos takes us on an irresistible and revelatory journey through the biggest of the big questions. What is reality? Could we exist without space and time? Can we travel to the past? What are the limits of the universe? Brian Greene has made the mysteries of space and time accessible to millions with his acclaimed writings and award-winning TV series. Now he reveals a world more beautiful and bizarre than we could have imagined, where 'dark matter' reigns, space warps and wiggles through eleven dimensions, minute particles dance, fizz and teleport across vast distances, everything is made of vibrating strings and, like an ant on a lily-pad, we may be floating on a sliver of spacetime. Revealing new layers of reality that lie just beneath the surface of our everyday lives, this grand tour of the universe will make you look at the world in a completely new way. 'A must-read' Sunday Times 'Greene takes us to the limits of space and time' Guardian 'Sends the reader's imagination hurtling through the universe on an astonishing ride' The New York Times Brian Greene is well known to many fans as a populariser of theoretical physics. He is the author of the bestselling books about string theory, The Elegant Universe, which was a finalist for the Pulitzer Prize for nonfiction, The Fabric of the Cosmos, and The Hidden Reality. Educated at Harvard and Oxford, he has taught at both Harvard and Cornell and has been Professor of Physics and Mathematics at Columbia University since 1996.

From the Nobel Prize-winning physicist, a personal meditation on the quest for objective reality in natural science A century ago, thoughtful people questioned how reality could agree with physical theories that keep changing, from a mechanical model of the ether to electric and magnetic fields, and from homogeneous matter to electrons and atoms. Today, concepts like dark matter and dark energy further complicate and enrich the search for objective reality. The Whole Truth is a personal reflection on this ongoing quest by one of the world's most esteemed cosmologists. What lies at the heart of physical science? What are the foundational ideas that inform and guide the enterprise? Is the concept of objective reality meaningful? If so, do our established physical theories usefully approximate it? P. J. E. Peebles takes on these and other big questions about the nature of science, drawing on a lifetime of experience as a leading physicist and using cosmology as an example. He traces the history of thought about the nature of physical science since Einstein, and succinctly lays out the fundamental working assumptions. Through a careful examination of the general theory of relativity, Einstein's cosmological principle, and the theory of an expanding universe, Peebles shows the evidence that we are discovering the nature of reality in successive approximations through increasingly rigorous scrutiny. A landmark work, The Whole Truth is essential reading for anyone interested in the practice of science.

This book summarizes and presents the scientific search for life in the universe, and the current level of scientific understanding of how life begins, grows, and becomes intelligent in our Solar System and beyond. This engaging book promises to appeal not only to the general reader but to scientists as well, many of whom strive to acquire an informed perspective on the search for extraterrestrial life in fields not their own.
