A concise introduction to the greatest questions of modern cosmology. What came before the big bang? How will the universe evolve into the future? Will there be a big crunch? Questions like these have no definitive answers, but there are many contending theories. In A Little Book about the Big Bang, physicist and writer Tony Rothman guides expert and uninitiated readers alike through the most compelling mysteries surrounding the nature and origin of the universe. Cosmologists are busy these days, actively researching dark energy, dark matter, and quantum gravity, all at the foundation of our understanding of space, time, and the laws governing the universe. Enlisting thoughtful analogies and a step-by-step approach, Rothman breaks down what is known and what isn't and details the pioneering experimental techniques scientists are bringing to bear on riddles of nature at once utterly basic and stunningly complex. In Rothman's telling, modern cosmology proves to be an intricate web of theoretical predictions confirmed by exquisitely precise observations, all of which make the theory of the big bang one of the most solid edifices ever constructed in the history of science. At the same time, Rothman is careful to distinguish established physics from speculation, and in doing so highlights current controversies and avenues of future exploration. The idea of the big bang is now almost a century old, yet with each new year comes a fresh enigma. That is scientific progress in a nutshell: every groundbreaking discovery, every creative explanation, provokes new and more fundamental questions. Rothman takes stock of what we have learned and encourages readers to ponder the mysteries to come.
In Assembling Life, David Deamer addresses questions that are the cutting edge of research on the origin of life. For instance, how did non-living organic compounds assemble into the first forms of primitive cellular life? What was the source of those compounds and the energy that produced the first nucleic acids? Did life begin in the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars? The book provides an overview of conditions on the early Earth four billion years ago and explains why fresh water hot springs are a plausible alternative to salty seawater as a site where life can begin. Deamer describes his studies of organic compounds that were likely to be available in the prebiotic environment and the volcanic conditions that can drive chemical evolution toward the origin of life. The book is not exclusively Earth-centric, but instead considers whether life could begin elsewhere in our solar system. Deamer does not propose how life did begin, because we can never know that with certainty. Instead, his goal is to understand how life can begin on any habitable planet, with Earth so far being the only known example.
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. Among the new developments that occurred during this period was the introduction of a particular notion of 'quasi-local mass-momentum and angular momentum', the topic of Penrose's Royal Society paper. Many encouraging results were initially obtained but, later, difficulties began to emerge and remain today. Also, an extensive paper (with Eastwood and Wells) gives a thorough account of the relation between twistor cohomology and massless fields. This volume witnesses Penrose's increasing conviction that the puzzling issue of quantum measurement could only be resolved by the appropriate unification of quantum mechanics with general relativity, where that union must involve an actual change in the rules of quantum mechanics as well as in space-time structure. Penrose's first incursions into a possible relation between consciousness and quantum state reduction are also covered here.
Professor Sir Roger Penrose's work, spanning fifty years of science, with over five thousand pages and more than three hundred papers, has been collected together for the first time and arranged chronologically over six volumes, each with an introduction from the author. Where relevant, individual papers also come with specific introductions or notes. This sixth volume describes an actual experiment to measure the length of time that a quantum superposition might last (developing the Diosi-Penrose proposal). It also discusses the significant progress made in relation to incorporating the 'googly' information for a gravitational field into the structure of a curved twistor space. Penrose also covers such things as the geometry of light rays in relation to twistor-space structures, the utility of complex numbers in drawing three-dimensional shapes, and the geometrical representation of different types of musical scales. The turn of the millennium was also an opportunity to reflect on progress in many areas up until that point.
Present-day elliptical, spiral and irregular galaxies are large systems made of stars, gas and dark matter. Their properties result from a variety of physical processes that have occurred during the nearly fourteen billion years since the Big Bang. This comprehensive textbook, which bridges the gap between introductory and specialized texts, explains the key physical processes of galaxy formation, from the cosmological recombination of primordial gas to the evolution of the different galaxies that we observe in the Universe today. In a logical sequence, the book introduces cosmology, illustrates the properties of galaxies in the present-day Universe, then explains the physical processes behind galaxy formation in the cosmological context, taking into account the most recent developments in this field. The text ends on how to find distant galaxies with multi-wavelength observations, and how to extract the physical and evolutionary properties based on imaging and spectroscopic data.
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 deals with neutrino physics and astrophysics - a field in which some of the most exciting recent developments in particle physics, astrophysics and cosmology took place. The book is the most up-to-date, comprehensive and self-contained treatment of key issues in neutrino physics. It discusses all the topics vital to the understanding of the nature of neutrinos such as what they are, how to describe them, how they behave in nature, and the roles that neutrinos play in shaping our Universe. The book provides comprehensive discussions, both experimental and theoretical, with relevant mathematical details, on neutrino oscillations, extra-terrestrial as well as terrestrial neutrinos and the relic neutrinos. It also discusses many implications of current experimental data on reactor, accelerator, atmospheric, solar and supernova neutrinos with future perspectives. The book starts with an introduction to field theory and gauge theory which is accessible even to advanced undergraduate students, with helpful appendices, and it also provides pedagogical but sufficiently detailed reviews of supernova physics and cosmology, in particular the Cosmic Microwave Background Radiation. It aims to provide all the technical details necessary for the professionals in the field and to be an almost exhaustive reference for neutrino physicists with over 1000 references.
An Introduction to Modern Cosmology Third Edition is an accessible account of modern cosmological ideas. The Big Bang Cosmology is explored, looking at its observational successes in explaining the expansion of the Universe, the existence and properties of the cosmic microwave background, and the origin of light elements in the universe. Properties of the very early Universe are also covered, including the motivation for a rapid period of expansion known as cosmological inflation. The third edition brings this established undergraduate textbook up-to-date with the rapidly evolving observational situation. This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader s understanding and learning. Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology. Supplementary material, including full-colour images, updates and links for students and instructors, is available on the author s website: http://www.roe.ac.uk/~arl/.

This is a substantially revised and updates new edition of a classic introductory textbook. Although there are a wealth of cosmology texts at postgraduate level, Cosmology remains the classic introduction to modern cosmology for undergraduates. While designed as the main text for a course given at second or third year level, it is sufficiently self-contained for anyone with school science to understand. There is a strong emphasis on observational cosmology, with introductory chapters on the visible universe, our galaxy and other galaxies and the empirical basis for cosmological theory. After an account of the big bang model, there are chapters on the early stages of the big bang and galaxy formation. Finally, there are chapters on cosmological tests and on alternative theories. One feature of the book it its updated epilogue of twenty controversies on cosmology today. The latest results from the WMAP mission are included and a wealth of new material, including a stronger emphasis on the cosmological constant. It has an extensive glossary and the exercises have been substantially expanded. A stronger emphasis on the physical basis for cosmology is included throughout.
What is time? The Janus Point offers a ground-breaking solution to one of the greatest mysteries in physics. For over a century, the greatest minds have sought to understand why time seems to flow in one direction, ever forward. In The Janus Point, Julian Barbour offers a radically new answer: it doesn't. At the heart of this book, Barbour provides a new vision of the Big Bang - the Janus Point - from which time flows in two directions, its currents driven by the expansion of the universe and the growth of order in the galaxies, planets and life itself. What emerges is not just a revolutionary new theory of time, but a hopeful argument about the destiny of our universe. 'Both a work of literature and a masterpiece of scientific thought' Lee Smolin, author of The Trouble with Physics 'Profound...original...accessible to anyone who has pondered the mysteries of space and time' Martin Rees, Astronomer Royal 'Takes on fundamental questions, offering a new perspective on how the Universe started and where it may be headed' Science Magazine
Carl Sagan once noted that there is only one generation that gets to see things for the first time. We are in the midst of such a time right now, standing on the threshold of discovery in the young and remarkable field of X-ray astronomy. In The Restless Universe, astronomer Eric Schlegel offers readers an informative survey of this cutting-edge science. Two major space observatories launched in the last few years--NASA's Chandra and the European Newton--are now orbiting the Earth, sending back a gold mine of data on the X-ray universe. Schlegel, who has worked on the Chandra project for seven years, describes the building and launching of this space-based X-ray observatory. But the book goes far beyond the story of Chandra. What Schlegel provides here is the background a nonscientist would need to grasp the present and follow the future of X-ray astronomy. He looks at the relatively brief history of the field, the hardware used to detect X-rays, the satellites--past, present, and future--that have been or will be flown to collect the data, the way astronomers interpret this data, and, perhaps most important, the insights we have already learned as well as speculations about what we may soon discover. And throughout the book, Schlegel conveys the excitement of looking at the universe from the perspective brought by these new observatories and the sharper view they deliver. Drawing on observations obtained from Chandra, Newton, and previous X-ray observatories, The Restless Universe gives a first look at an exciting field which significantly enriches our understanding of the universe.
#1 NEW YORK TIMES BESTSELLER - The world-famous cosmologist and author of A Brief History of Time leaves us with his final thoughts on the biggest questions facing humankind. "Hawking's parting gift to humanity . . . a book every thinking person worried about humanity's future should read."--NPR NAMED ONE OF THE BEST BOOKS OF THE YEAR BY Forbes - The Guardian - Wired Stephen Hawking was the most renowned scientist since Einstein, known both for his groundbreaking work in physics and cosmology and for his mischievous sense of humor. He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live. In later life he could communicate only by using a few facial muscles, but he continued to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe's greatest mysteries but also believed science plays a critical role in fixing problems here on Earth. Now, as we face immense challenges on our planet--including climate change, the threat of nuclear war, and the development of artificial intelligence--he turns his attention to the most urgent issues facing us. Will humanity survive? Should we colonize space? Does God exist? These are just a few of the questions Hawking addresses in this wide-ranging, passionately argued final book from one of the greatest minds in history. Featuring a foreword by Eddie Redmayne, who won an Oscar playing Stephen Hawking, an introduction by Nobel Laureate Kip Thorne, and an afterword from Hawking's daughter, Lucy, Brief Answers to the Big Questions is a brilliant last message to the world. Praise for Brief Answers to the Big Questions "[Hawking is] a symbol of the soaring power of the human mind."--The Washington Post "Hawking's final message to readers . . . is a hopeful one."--CNN "Brisk, lucid peeks into the future of science and of humanity."--The Wall Street Journal "Hawking pulls no punches on subjects like machines taking over, the biggest threat to Earth, and the possibilities of intelligent life in space."--Quartz "Effortlessly instructive, absorbing, up to the minute and--where it matters--witty."--The Guardian "This beautiful little book is a fitting last twinkle from a new star in the firmament above."--The Telegraph
Can animals be persons? To this question, scientific and philosophical consensus has taken the form of a resounding, 'No!' In this book, Mark Rowlands disagrees. Not only can animals be persons, many of them probably are. Taking, as his starting point, John Locke's classic definition of a person, as "a thinking intelligent being, that has reason and reflection, and can consider itself the same thinking thing, in different times and places," Rowlands argues that many animals can satisfy all of these conditions. A person is an individual in which four features coalesce: consciousness, rationality, self-awareness and other-awareness, and many animals are such individuals. Consciousness-something that is like to have an experience-is widely distributed through the animal kingdom. Many animals are capable of both causal and logical reasoning. Many animals are also self-aware, since a form of self-awareness is essentially built into the possession of conscious experience. And some animals are capable of a kind of awareness of the minds of others, quite independently of whether they possess a theory of mind. This is not just a book about animals, however. As well as being fascinating in their own right, animals, as Claude Levi-Strauss once put it, are "good to think." In this seamless interweaving of the empirical study of animal minds with philosophy and its history, this book makes a powerful case for the idea that reflection on animals allows us to better understand each of these four pillars of personhood, and so illuminates what means for any individual-animal or human-to be conscious, rational, self- and other-aware.
1919 hat das Preussische Ministerium fur Wissenschaft, Kunst und Volksbildung die Akte "Einsteins Relativitatstheorie" angelegt. Der Autor, selbst Wissenschaftshistoriker, hat sie 1961 gefunden und zusammen mit anderen inzwischen identifizierten "Einstein"-Akten aus deutschen Archiven als Quellmaterial fur dieses faszinierende Buch gewahlt. Eingeteilt in drei Abschnitte: "Im Kaiserreich"-"In der Weimarer Republik"-"Das dritte Reich" zeichnet das Buch das Einsteinbild nach, zeigt auf, wie der Wissenschaftler immer starker durch die Ereignisse dieser turbulenten Jahre zu einer politischen Figur wurde und tragt Neues zum besseren Verstehen fur Einsteins rigorosen Bruch mit Deutschland bei. Damit fullt der Autor eine wichtige Lucke in der Einsteinliteratur. In der Neuauflage kommt noch ein Abschnitt hinzu, in dem der Autor bisher unbekanntes Material zu den FBI- und CIC-Berichten uber Einsteins angebliche Kontakte zur KPD und Komintern vorlegt. Des weiteren wird Einsteins Mitarbeit in der Volkerbundkommission erstmals in Tiefe behandelt."
Im Alter von 21 Jahren hat W. Pauli einen Handbuchartikel zur Relativitatstheorie verfasst, der bis heute gelesen und zitiert wird. Er ist wohl der beruhmteste Text zum Thema und wurde nicht zuletzt von A. Einstein begeistert gewurdigt. Die vorliegende Neuausgabe enthalt den Originalartikel sowie weitere, teilweise recht ausfuhrliche Erganzungen, die Pauli im Jahre 1956 fur die englische Ausgabe schrieb. Eine Reihe von Anmerkungen des Herausgebers dienen daruber hinaus als Lesehilfen und zeigen Verbindungen zu modernen Entwicklungen auf."
Obwohl der Mundigkeitsbegriff seine herausragende Stellung in der erziehungswissenschaftlichen Diskussion mittlerweile eingebusst hat, ist er immer noch als Erziehungsziel gegenwartig. Wer von Mundigkeit redet, meint - mal mehr, mal weniger explizit - das Verantwortung begrundende Freiheitsvermoegen, sich selbst regieren zu koennen. Angenommen, die moderne Hirnforschung hatte Recht und Freiheit ware tatsachlich nur eine Illusion, musste mit der Unmoeglichkeit von Freiheit und Verantwortung konsequenterweise auch der Mundigkeitsbegriff verworfen werden. Kants Idee der Freiheit zeigt, warum Freiheit trotz (neuronaler) Determination widerspruchsfrei gedacht werden kann. Diese Fundierung des Mundigkeitsbegriffs in der Idee der Freiheit schrankt zugleich auch die Bandbreite dessen ein, was Mundigkeit sein kann und nimmt dem Begriff so seine Beliebigkeit.
Der Glaube an die Gesetzmassigkeit der Natur, das Streben, allge- meine und universell gultige Gesetze zu finden, und die Hoffnung - oder sogar Erwartung -, der Wahrheit uber die Wirklichkeit naher zu kommen, haben ihren Grund in einer besonderen persoenlichen Welt- sicht, die tiefere Wurzeln als alle naturwissenschaftlichen Disziplinen und philosophischen Systeme hat. Der persoenliche Kontakt mit einem schoepferischen Geist ist anre- gend, er verstarkt den Drang nach Verstehen und vergroessert die Be- friedigung, wenn Aufklarung zuteil wurde. Wenn dies durch Mathema- tik oder eine theoretische Disziplin erfolgt, ist diese Befriedigung dem Vergnugen verwandt, das man an schoener Musik oder anderen wahren Kunstwerken empfindet. Es war mein grosses Gluck, an der Universitat Berlin studieren zu koennen, als Einstein, von Laue und Planck dort lehrten. Ihr Werk pragte mich stark und dauerhaft. Ich erhielt Einblick in ihr Denken, die ihnen eigenen Methoden und schliesslich in ihre Persoenlichkeit. Ich moechte einige meiner Erinnerungen in der Hoffnung wiedergeben, ihre Ansichten und ihre Persoenlichkeit fur die, die sie kannten, lebendig zu erhalten und fur alle anderen erstehen zu lassen.
Magnetic fields pervade the universe and play an important role in many astrophysical processes. However, they require specialised observational tools, and are challenging to model and understand. This volume provides a unified view of magnetic fields across astrophysical and cosmological contexts, drawing together disparate topics that are rarely covered together. Written by the lecturers of the XXV Canary Islands Winter School, it offers a self-contained introduction to cosmic magnetic fields on a range of scales. The connections between the behaviours of magnetic fields in these varying contexts are particularly emphasised, from the relatively small and close ranges of the Sun, planets and stars, to galaxies and clusters of galaxies, as well as on cosmological scales. Aimed at young researchers and graduate students, this up-to-date review uniquely brings together a subject often tackled by disconnected communities, conveying the latest advances as well as highlighting the limits of our current understanding.
'Mindblowing' Michael Pollan Why do we know so much more about the cosmos than our own consciousness? Are there limits to the scientific method? Why do we assume that only science, mathematics and technology reveal truth? The Flip shows us what happens when we realise that consciousness is fundamental to the cosmos and not some random evolutionary accident or surface cognitive illusion; that everything is alive, connected, and 'one'. We meet the people who have made this visionary, intuitive leap towards new forms of knowledge: Mark Twain's prophetic dreams, Marie Curie's seances, Einstein's cosmically attuned mind. But these forms of knowledge are not archaic; indeed, they are essential in a universe that has evolved specifically to be understandable by the consciousnesses we inhabit. The Flip peels back the layers of our beliefs about the world to reveal a visionary, new way of understanding ourselves and everything around us, with huge repercussions for how we live our lives. After all, once we have flipped, we understand that the cosmos is not just human. The human is also cosmic. |
