| understanding our universe 2nd edition: The End of Everything Katie Mack, 2020-08-04 A NEW YORK TIMES NOTABLE BOOK * AN NPR SCIENCE FRIDAY BOOK CLUB SELECTION* NAMED A BEST BOOK OF THE YEAR BY THE WASHINGTON POST, THE ECONOMIST, NEW SCIENTIST, PUBLISHERS WEEKLY, and THE GUARDIAN From the cohost of the podcast The Universe with John Green and one of the most dynamic stars in astrophysics, an “engrossing, elegant” (The New York Times) look at five ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology. We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now? Dr. Katie Mack has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant. This revelation set her on the path toward theoretical astrophysics. Now, with lively wit and humor, she takes us on a mind-bending tour through five of the cosmos’s possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know. |
| understanding our universe 2nd edition: Our Place in the Universe Sun Kwok, 2017-04-22 If you have ever wanted to understand the basic principles of astronomy and celestial movements, you should read this book. Using pictures of the sky observed from different places on Earth, as well as drawings of ancient astronomical methods and tools, Prof. Sun Kwok tells this story in an entertaining and fascinating way. Since the beginning of human civilization, people have wondered about the structure of the cosmos and our place in the Universe. More than 2,000 years ago, our ancestors knew that the seasons were unequal, the Earth was an unattached object floating in space, and stars existed that they could not see. From celestial observations, they concluded that the Earth was round. Using simple tools and mathematics, ancient astronomers accurately determined the sizes of the Earth and Moon, the distance to the Moon, and the lengths of the months and year. With a clever device called the armillary sphere, Greek astronomers could predict the times of sunrise and sunset on any day of the year, at any place on Earth. They developed sophisticated mathematical models to forecast Mars’ motions hundreds of years into the future. Find out how ancient observers achieved these remarkable feats. With minimal use of mathematics, this book retraces the footsteps of our ancestors, explains their intellectual journeys in simple terms, and explores the philosophical implications of these discoveries. |

| understanding our universe 2nd edition: Before the Beginning Martin J. Rees, 2002 The experimental and theoretical successes of cosmology in recent years offer the most dramatic enlargement of our concept of the universe since astronomers first realised the Sun's true place among the stars. In this groundbreaking, thought-provoking and accessible book Professor Sir Martin Rees argues that our universe is just one element in an infinite ensemble, a cosmic archipelago where impassable barriers prohibit communication between the islands. Our 'home universe' is an exceptional member of this ensemble, however, not least because it contains creatures able to observe it and contemplate its nature, past and future. One of these is Rees himself: one of the most creative and original of contemporary scientists, and a wonderful guide to the mysteries of the cosmos. |

Fascinating from first to last—this is a book that has already prompted the attention and admiration of some of the most prominent scientists and mathematicians. |
| understanding our universe 2nd edition: Foundations for Moral Relativism J. David Velleman, 2015-11-23 In this new edition of Foundations for Moral Relativism a distinguished moral philosopher tames a bugbear of current debate about cultural difference. J. David Velleman shows that different communities can indeed be subject to incompatible moralities, because their local mores are rationally binding. At the same time, he explains why the mores of different communities, even when incompatible, are still variations on the same moral themes. The book thus maps out a universe of many moral worlds without, as Velleman puts it, moral black holes”. The six self-standing chapters discuss such diverse topics as online avatars and virtual worlds, lying in Russian and truth-telling in Quechua, the pleasure of solitude and the fear of absurdity. Accessibly written, this book presupposes no prior training in philosophy. |
| understanding our universe 2nd edition: The New Cosmic Story John F. Haught, 2017-01-01 A foremost thinker on science and religion argues that an adequate understanding of cosmic history requires attention to the emergence of interiority, including religious aspiration Over the past two centuries scientific advances have made it clear that the universe is a story still unfolding. In this thought-provoking book, John F. Haught considers the deeper implications of this discovery. He contends that many others who have written books on life and the universe--including Stephen Hawking, Stephen Jay Gould, and Richard Dawkins--have overlooked a crucial aspect of cosmic history: the drama of life's awakening to interiority and religious awareness. Science may illuminate the outside story of the universe, but a full telling of the cosmic story cannot ignore the inside development that interiority represents. Haught addresses two primary questions: what does the arrival of religion tell us about the universe, and what does our understanding of the cosmos as an unfinished drama tell us about religion? The history of religion may be ambiguous and sometimes even barbarous, he asserts, but its role in the story of cosmic emergence and awakening must be taken into account. |

| understanding our universe 2nd edition: Peace Operations Paul F. Diehl, 2013-08-26 Peacekeeping has gradually evolved to encompass a broad range of different conflict management missions and techniques, which are incorporated under the term peace operations. Well over 100 missions have been deployed, the vast majority within the last twenty years. This book provides an overview of the central issues surrounding the development, operation, and effectiveness of peace operations. Among many features, the book: Traces the historical development of peace operations from their origins in the early 20th century through the development of modern peacebuilding missions. Tracks changes over time in the size, mission, and organization of peace operations. Analyses different organizational, financial, and troop provisions for peace operations, as well as assessing alternatives. Lays out criteria for evaluating peace operations and details the conditions under which such operations are successful. As peace operations become the primary mechanism of conflict management used by the UN and regional organizations, understanding their problems and potential is essential for a more secure world. Drawing on a wide range of examples from those between Israel and her neighbors to more recent operations in Somalia and the Congo, this book brings together the body of scholarly research on peace operations to address those concerns. It will be an indispensable guide for students, practitioners and general readers wanting to broaden their knowledge of the possibilities and limits of peace operations today. |

| understanding our universe 2nd edition: How to Make an Apple Pie from Scratch Harry Cliff, 2021-08-10 NAMED A BEST SCIENCE BOOK OF 2021 BY KIRKUS * An acclaimed experimental physicist at CERN takes you on an exhilarating search for the most basic building blocks of our universe, and the dramatic quest to unlock their cosmic origins. A fascinating exploration of how we learned what matter really is, and the journey matter takes from the Big Bang, through exploding stars, ultimately to you and me. (Sean Carroll) Carl Sagan once quipped, “If you wish to make an apple pie from scratch, you must first invent the universe.” But finding the ultimate recipe for apple pie means answering some big questions: What is matter really made of? How did it escape annihilation in the fearsome heat of the Big Bang? And will we ever be able to understand the very first moments of our universe? In How to Make an Apple Pie from Scratch, Harry Cliff—a University of Cambridge particle physicist and researcher on the Large Hadron Collider—sets out in pursuit of answers. He ventures to the largest underground research facility in the world, deep beneath Italy's Gran Sasso mountains, where scientists gaze into the heart of the Sun using the most elusive of particles, the ghostly neutrino. He visits CERN in Switzerland to explore the Antimatter Factory, where the stuff of science fiction is manufactured daily (and we're close to knowing whether it falls up). And he reveals what the latest data from the Large Hadron Collider may be telling us about the fundamental nature of matter. Along the way, Cliff illuminates the history of physics, chemistry, and astronomy that brought us to our present understanding—and misunderstandings—of the world, while offering readers a front-row seat to one of the most dramatic intellectual journeys human beings have ever embarked on. A transfixing deep dive into the origins of our world, How to Make an Apple Pie from Scratch examines not just the makeup of our universe, but the awe-inspiring, improbable fact that it exists at all. |

Specific kinds of blogs discussed include political blogs, citizen journalism, confessional blogs and commercial blogs. |
| understanding our universe 2nd edition: Cosmology for the Curious Delia Perlov, Alex Vilenkin, 2024-10-03 This book is a gentle introduction for all those wishing to learn about modern views of the cosmos. Our universe originated in a great explosion – the big bang. For nearly a century cosmologists have studied the aftermath of this explosion: how the universe expanded and cooled down, and how galaxies were gradually assembled by gravity. The nature of the bang itself has come into focus only relatively recently. It is the subject of the theory of cosmic inflation, which was developed in the last few decades and has led to a radically new global view of the universe. Students and other interested readers will find here a non-technical but conceptually rigorous account of modern cosmological ideas - describing what we know, and how we know it. One of the book's central themes is the scientific quest to find answers to the ultimate cosmic questions: Is the universe finite or infinite? Has it existed forever? If not, when and how did it come into being? Will it ever end? The book is based on the undergraduate course taught by Alex Vilenkin at Tufts University. It assumes no prior knowledge of physics or mathematics beyond elementary high school math. The necessary physics background is introduced as it is required. Each chapter includes a list of questions and exercises of varying degree of difficulty. This new edition includes hints for answering the questions and exercises, as well as extensions to the discussions on dark matter, quantum cosmology. A new chapter summarizing the standard cosmological model has also been added. |
| understanding our universe 2nd edition: The Cosmic 21-cm Revolution Andrei Mesinger, 2019-12-23 The redshifted 21-cm signal is set to transform astrophysical cosmology, bringing a historically data-starved field into the era of Big Data. Corresponding to the spin-flip transition of neutral hydrogen, the 21-cm line is sensitive to the temperature and ionization state of the cosmic gas, as well as to cosmological parameters. Crucially, with the development of new interferometers it will allow us to map out the first billion years of our Universe, enabling us to learn about the properties of the unseen first generations of galaxies. Rapid progress is being made on both the observational and theoretical fronts, and important decisions on techniques and future direction are being made. The Cosmic 21-cm Revolution gathers contributions from current leaders in this fast-moving field, providing both an overview for graduate students and a reference point for current researchers. |
| understanding our universe 2nd edition: Elementary Cosmology James J Kolata, 2015-12-01 Cosmology is the study of the origin, size, and evolution of the entire universe. Every culture has developed a cosmology, whether it be based on religious, philosophical, or scientific principles. In this book, the evolution of the scientific understanding of the Universe in Western tradition is traced from the early Greek philosophers to the most modern 21st century view. After a brief introduction to the concept of the scientific method, the first part of the book describes the way in which detailed observations of the Universe, first with the naked eye and later with increasingly complex modern instruments, ultimately led to the development of the Big Bang theory. The second part of the book traces the evolution of the Big Bang including the very recent observation that the expansion of the Universe is itself accelerating with time. |
| understanding our universe 2nd edition: The Accidental Universe Alan Lightman, 2014-01-14 The bestselling author of Einsteins Dreams explores the emotional and philosophical questions raised by recent discoveries in science with passion and curiosity. He looks at the dialogue between science and religion; the conflict between our human desire for permanence and the impermanence of nature; the possibility that our universe is simply an accident; the manner in which modern technology has separated us from direct experience of the world; and our resistance to the view that our bodies and minds can be explained by scientific logic and laws. Behind all of these considerations is the suggestion--at once haunting and exhilarating--that what we see and understand of the world is only a tiny piece of the extraordinary, perhaps unfathomable whole. |
| understanding our universe 2nd edition: The Beginning of Infinity David Deutsch, 2011-07-21 The New York Times bestseller: A provocative, imaginative exploration of the nature and progress of knowledge “Dazzling.” – Steven Pinker, The Guardian In this groundbreaking book, award-winning physicist David Deutsch argues that explanations have a fundamental place in the universe—and that improving them is the basic regulating principle of all successful human endeavor. Taking us on a journey through every fundamental field of science, as well as the history of civilization, art, moral values, and the theory of political institutions, Deutsch tracks how we form new explanations and drop bad ones, explaining the conditions under which progress—which he argues is potentially boundless—can and cannot happen. Hugely ambitious and highly original, The Beginning of Infinity explores and establishes deep connections between the laws of nature, the human condition, knowledge, and the possibility for progress. |
| understanding our universe 2nd edition: The Five Ages of the Universe Fred C.

'Nature of Science' and 'Detectives on the Case' sections in each chapter encourage students to take on the role of a scientist and so develop an understanding of how scientific progress is made, leading students through a chain of arguments of forming and testing hypotheses, in the context of specific astronomical topics. By focusing on key topics, the student is able to develop a deeper understanding of the core areas of astronomy. Math is used to make intuitive points and kept simple by using a two-track system to first describe the logic of the calculation followed by a more detailed example. Simple illustrations support the text and step students through concepts visually. |

| understanding our universe 2nd edition: The Tyranny of Science Paul K. Feyerabend, 2011-05-06 Paul Feyerabend is one of the greatest philosophers of science of the 20th century and his book Against Method is an international bestseller. In this new book he masterfully weaves together the main elements of his mature philosophy into a gripping tale: the story of the rise of rationalism in Ancient Greece that eventually led to the entrenchment of a mythical ‘scientific worldview’. In this wide-ranging and accessible book Feyerabend challenges some modern myths about science, including the myth that ‘science is successful’. He argues that some very basic assumptions about science are simply false and that substantial parts of scientific ideology were created on the basis of superficial generalizations that led to absurd misconceptions about the nature of human life. Far from solving the pressing problems of our age, such as war and poverty, scientific theorizing glorifies ephemeral generalities, at the cost of confronting the real particulars that make life meaningful. Objectivity and generality are based on abstraction, and as such, they come at a high price. For abstraction drives a wedge between our thoughts and our experience, resulting in the degeneration of both. Theoreticians, as opposed to practitioners, tend to impose a tyranny on the concepts they use, abstracting away from the subjective experience that makes life meaningful. Feyerabend concludes by arguing that practical experience is a better guide to reality than any theory, by itself, ever could be, and he stresses that there is no tyranny that cannot be resisted, even if it is exerted with the best possible intentions. Provocative and iconoclastic, The Tyranny of Science is one of Feyerabend’s last books and one of his best. It will be widely read by everyone interested in the role that science has played, and continues to play, in the shaping of the modern world. |

| understanding our universe 2nd edition: Just Six Numbers Martin Rees, 2014-03-20 Astronomer Royal Martin Rees shows how the behaviour and origins of the universe can be explained by just six numbers. How did a single genesis event create billions of galaxies, black holes, stars and planets? How did atoms assemble - here on Earth, and perhaps on other worlds - into living beings intricate enough to ponder their origins? This book describes the recent avalanche of discoveries about the universe's fundamental laws, and the deep connections that exist between stars and atoms - the cosmos and the microscopic world. Just six numbers, imprinted in the big bang, determine the essence of our world, and this book devotes one chapter to explaining each. |
