This book is a historical account of how natural philosophers and scientists have endeavoured to understand the universe at large, first in a mythical and later in a scientific context. Starting with the creation stories of ancient Egypt and Mesopotamia, the book covers all the major events in theoretical and observational cosmology, from Aristotle's cosmos over the Copernican revolution to the discovery of the accelerating universe in the late 1990s. It presents cosmology as a subject including scientific as well as non-scientific dimensions, and tells the story of how it developed into a true science of the heavens. Contrary to most other books in the history of cosmology, it offers an integrated account of the development with emphasis on the modern Einsteinian and post-Einsteinian period. Starting in the pre-literary era, it carries the story onwards to the early years of the 21st century.
In each generation, scientists must redefine their fields: abstracting, simplifying and distilling the previous standard topics to make room for new advances and methods. Sethna's book takes this step for statistical mechanics--a field rooted in physics and chemistry whose ideas and methods< br> are now central to information theory, complexity, and modern biology. Aimed at advanced undergraduates and early graduate students in all of these fields, Sethna limits his main presentation to the topics that future mathematicians and biologists, as well as physicists and chemists, will find< br> fascinating and central to their work. The amazing breadth of the field is reflected in the author's large supply of carefully crafted exercises, each an introduction to a whole field of study: everything from chaos through information theory to life at the end of the universe.
The book begins with a brief review of supersymmetry and the construction of the minimal supersymmetric standard model and approaches to supersymmetry breaking. General non-perturbative methods are also reviewing leading to the development of holomorphy and the Affleck-Dine-Seiberg superpotential as powerful tools for analyzing supersymmetric theories. Seiberg duality is discussed in detail, with many example applications provided, with special attention paid to its use in understanding dynamical supersymmetry breaking. The Seiberg-Witten theory of monopoles is introduced through the analysis of simpler N=1 analogues. Superconformal field theories are described along with the most recent development known as "a-maximization." Supergravity theories are examined in 4, 10, and 11 dimensions, allowing for a discussion of anomaly and gaugino mediation, and setting the stage for the anti-de-Sitter/conformal field theory correspondence. This book is unique in containing an overview of the important developments in supersymmetry since the publication of "Supersymmetry and Supergravity" by Wess and Bagger. It also strives to cover topics that are of interest to both formal and phenomenological theorists.
Our vast Universe is filled with an enormous amount of matter and energy, which are the source of large gravitational potentials affecting all physical phenomena. Because this fact about the size and contents of the Universe was not known when our fundamental theories of dynamics and relativity were completed by the 1920s, the current theories - based as they are in empty space - fail to incorporate cosmic gravity. Though the current theories are consistent with the majority of empirical facts, there are some crucial discrepancies, which demand a drastic shift to a cosmic gravitational paradigm for the theories of relativity and dynamics. The book is a detailed and widely accessible account of this paradigm, called Cosmic Relativity, supported by ample empirical evidence. It is established that all motional relativistic effects are cosmic gravitational effects. The new theory of Cosmic Relativity solves and answers all outstanding questions and puzzles about dynamics and relativity.
'Witty, approachable and captivating' - Robin Ince 'A fascinating exploration of how we learned what matter really is' - Sean Carroll 'A delightfully fresh and accessible approach to one of the great quests of science' - Graham Farmelo 'Lays out not just what we know, but how we found out (and what is left to be discovered' - Katie Mack 'If you wish to make an apple pie from scratch, you must first invent the universe' - Carl Sagan Inspired by Sagan's famous line, How To Make An Apple Pie From Scratch sets out on a journey to unearth everything we know about our universe: how it started, how we found out, and what we still have left to discover. Will we ever be able to understand the very first moments of the world we inhabit? What is matter really made of? How did anything survive the fearsome heat of the Big Bang? In pursuit of answers, we meet the scientists, astronomers and philosophers who brought us to our present understanding of the world - offering readers a front-row seat to the most dramatic journey human beings have ever embarked on. Harry Cliff's How To Make An Apple Pie From Scratch is an essential, fresh and funny guide to how we got to where we are now - and what we have to come.
Manolis Plionis & Spiros Cotsakis plionis@sapfo. astro. noa. gr skot@aegean. gr Since the dawn of human civilisation natural phenomena have been subject to observation and investigation by the humans who initially ascribed to them 'divine' powers. Gods of 'good' and 'evil' werecreatedaccording to the useful- ness or notofsuch unexplained, atthetime, phenomena. Astheir understanding of the world developed and deepened, the divine powers, religious beliefs, su- perstitions and mysticism gave their place to the knowledge, limited that it may be, of physical reality. However, many issues have been and still are out of grasp of human understanding. These issues have always been at the center of philosophical, theological, and more recently, scientific debate. It is to us incredible that many of the conclusions concerning the true scientific explanation of the external world, to which the ancient Greeks arrived purely on the basis of abstract thought, came so near to modem scientific ideas and also form the basis of modem science. We cannot but stand with amazement at the original thoughts of Archimedes who, among his many extraordinary achieve- ments in mathematics and physics, calculated (cf. TheSandReckoner) the mass density of the observable universe and came up with a figure that is in complete agreement with current estimates coming from observational cosmology.
Covering the origins of life on Earth and our search for life elsewhere in the Universe, examining what life could look like, the ways scientists are looking for it and what we expect to find.
This text, written by two leading experts, reviews the historical observations of supernova explosions in our Galaxy over the past two thousand years and discusses modern observations of the remnants of these explosions at radio and other wavelengths.
Methods and Materials for Remote Sensing: Infrared Photo-Detectors,
Radiometers and Arrays presents the basic principles and the

Cosmology has become a very active research field in the last decades thanks to the impressing improvement of our observational techniques which have led to landmark discoveries such as the accelerated expansion of the universe, and have put physicists in front of new mysteries to unveil, such as the quest after the nature of dark matter and dark energy. These notes offer an approach to cosmology, covering fundamental topics in the field: the expansion of the universe, the thermal history, the evolution of small cosmological perturbations and the anisotropies in the cosmic microwave background radiation. Some extra topics are presented in the penultimate chapter and some standard results of physics and mathematics are available in the last chapter in order to provide a self-contained treatment. These notes offer an in-depth account of the above-mentioned topics and are aimed to graduate students who want to build an expertise in cosmology.
Extensively revised and updated, this new edition of David A. Rothery's acclaimed geological guide to the outer solar system includes results and close-up color and black and white images from the 1995-1999 Galileo mission to Jupiter and from the Voyager space probe. Rothery, a noted planetary scientist, explains the geological aspects of the major satellites of the outer bodies, from Jupiter and Neptune to the Pluto-Charon system. Rothery discusses their similarities and differences, and reveals how they resemble Earth-like planets. This fascinating book is written in an introductory style ideal for first or second year degree courses. Amateur geologists and astronomers will also find its insights rewarding. Reviews of the First Edition: 'The depth and authority of the treatment of physical geological processes makes this a good introduction to the outer satellites for undergraduate students, while the clarity of the text ensures that things do not become too complicated for less expert readers.' Lionel Wilson, Times Higher Education Supplement 'Rothery brings these satellites to life.' David Hughes, New Scientist
Introduction to Cosmology provides a rare combination of a solid foundation of the core physical concepts of cosmology and the most recent astronomical observations. The text is designed for advanced undergraduates or beginning graduate students and assumes no prior knowledge of general relativity. An emphasis is placed on developing the students' physical insight rather than losing them with complex math. An approachable writing style and wealth of fresh and imaginative analogies from "everyday" physics are used to make the concepts of cosmology more accessible.
Don Handelman's groundbreaking work in anthropology is showcased in this collection of his most powerful essays, edited by Matan Shapiro and Jackie Feldman. The book looks at the intellectual and spiritual roots of Handelman's initiation into anthropology; his work on ritual and on "bureaucratic logic"; analyses of cosmology; and innovative essays on Anthropology and Deleuzian thinking. Handelman reconsiders his theory of the forming of form and how this relates to a new theory of the dynamics of time. This will be the definitive collection of articles by one of the most important anthropologists of the late 20th Century.
'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, author of Something Deeply Hidden 'If you wish to make an apple pie from scratch, you must first invent the universe.' - Carl Sagan We probably all have a vague idea of how to make an apple pie: mix flour and butter, throw in some apples and you're probably most of the way there, right? Think again. Making an apple pie from scratch requires ingredients that definitely aren't available in the supermarket, ovens that can reach temperatures of trillions of degrees, and a preparation time of 13.8 billion years. Inspired by Sagan's famous line, Harry Cliff ventures out in search of the ultimate apple pie recipe, tracing the ingredients of our universe through the hearts of dying stars and back in time to a tiny fraction of a second after our universe began. Along the way, he confronts some really big questions: What is matter really made of? How does the stuff around us 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 pursuit of answers, Cliff 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 this stuff of science fiction is manufactured daily (and we're close to knowing whether it falls upwards). And he reveals what the latest data from the Large Hadron Collider may be telling us about the fundamental ingredients of matter. Along the way, Cliff illuminates the history of physics, chemistry, and astronomy that brought us to our present understanding 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 origins of our world, How to Make an Apple Pie from Scratch doesn't just put the makeup of our universe under the microscope, but the awe-inspiring, improbable fact that it exists at all.
How would Saturn’s rings look from a spaceship sailing just above them? If you were falling into a black hole, what’s the last thing you’d see before your spaghettification? What would it be like to visit the faraway places we currently experience only through high-powered telescopes and robotic emissaries? Faster-than-light travel may never be invented, but we can still take the scenic route through the universe with renowned astronomer and science communicator Philip Plait. On this lively, immersive adventure through the cosmos, Plait draws ingeniously on the latest scientific research to transport readers to ten spectacular sites, from our own familiar Moon to the outer reaches of our solar system and far beyond. Whether strolling through a dust storm under Mars’ butterscotch sky, witnessing the birth of a star or getting dizzy in a technicolour nebula, Plait is an illuminating, entertaining guide to the most otherworldly views in our universe.
Quantum cosmology has gradually emerged as the focus of devoted research, mostly within the second half of last century. As we entered the 21st century, the subject is still very much alive. The outcome of results and templates for investigation have been enlarged, some very recent and fascinating. Hence this book, where the authors bequeath some of their views, as they believe this current century is the one where quantum cosmology will be fully accomplished.Though some aspects are not discussed (namely, supersymmetry or loop structures), there are perhaps a set of challenges that in the authors' opinion remain, some since the dawn of quantum mechanics and applications to cosmology. Others could have been selected, at the readers' discretion and opinion. The authors put herewith a chart and directions to explore, some of which they have worked on or aimed to work more, in the twilight of their current efforts. Their confidence is that someone will follow in their trails, venturing in discovering the proper answer, by being able to formulate the right questions beforehand. The authors' shared foresight is that such discoveries, from those formulations, will be attained upon endorsing the routes within the challenges herewith indicated.
'Cosmic Paradoxes' was an outcome of a Conference-Summer Course on 'Astrophysical Cosmology: Frontier Questions' held at El Escorial, Madrid, on August 16-19, 1993. The Scientific Directors were John C Mather, Director of NASA's COBE (Cosmic Background Radiation Explorer), and Jose M Torroja, Secretary of the Spanish Academy of Sciences. Julio A Gonzalo, UAM, was in charge of coordinating the event. The first speaker was Ralph A Alpher, one of the pioneers who predicted very early the CBR (Cosmic Background Radiation). The CBR was observed by A Penzias and R Wilson, Bell Telephone Labs, in 1965. Thereafter it was measured with unprecedented precision by the COBE in 1989, characterizing the Planck spectral distribution of the CBR (J C Mather) and detecting its minute anisotropies (G Smoot). In 2003 the WMAP, NASA's satellite successor of the COBE, confirmed COBE's results, and gave an excellent quantitative estimate of the 'age' of the universe as 13.7 +/- 0.2 Gyrs, in support of the Big Bang theory of cosmic origins.In the Third Edition of this book, almost coincident with the launch reports of NASA's James Webb Space Telescope (JWST), includes recent work discussing evidence in favor of an open finite universe. A further discussion of the Heisenberg-Lemaitre time (Appendix D) takes into consideration that the cosmic expansion velocity at very early times is R(yHL) c and reviews in more detail the thermal history of the universe.

The growth of cosmology into a precision science represents one of the most remarkable stories of the past century. Much has been written chronicling this development, but rarely has any of it focused on the most critical element of this work-the cosmic spacetime itself. Addressing this lacuna is the principal focus of this book, documenting the growing body of evidence compelling us-not only to use this famous solution to Einstein's equations in order to refine the current paradigm, but-to probe its foundation at a much deeper level. Its excursion from the smallest to largest possible scales insightfully reveals an emerging link between the Universe we behold and the established tenets of our most fundamental physical theories. Key Features: Uncovers the critical link between the Local Flatness Theorem in general relativity and the symmetries informing the spacetime's metric coefficients Develops a physical explanation for some of the most unpalatable coincidences in cosmology Provides a sober assessment of the horizon problems precluding our full understanding of the early Universe Reveals a possible explanation for the origin of rest-mass energy in Einstein's theory In spite of its technical layout, this book does not shy away from introducing the principal players who have made the most enduring contributions to this field. Anyone with a graduate level foundation in physics and astronomy will be able to easily follow its contents.

Nanohertz Gravitational Wave Astronomy explores the exciting hunt for low frequency gravitational waves by using the extraordinary timing precision of pulsars. The book takes the reader on a tour across the expansive gravitational-wave landscape, from LIGO detections to the search for polarization patterns in the Cosmic Microwave Background, then hones in on the band of nanohertz frequencies that Pulsar Timing Arrays (PTAs) are sensitive to. Within this band may lie many pairs of the most massive black holes in the entire Universe, all radiating in chorus to produce a background of gravitational waves. The book shows how such extra-Galactic gravitational waves can alter the arrival times of radio pulses emanating from monitored Galactic pulsars, and how we can use the pattern of correlated timing deviations from many pulsars to tease out the elusive signal. The book takes a pragmatic approach to data analysis, explaining how it is performed in practice within classical and Bayesian statistics, as well as the numerous strategies one can use to optimize numerical Bayesian searches in PTA analyses. It closes with a complete discussion of the data model for nanohertz gravitational wave searches, and an overview of the past achievements, present efforts, and future prospects for PTAs. The book is accessible to upper division undergraduate students and graduate students of astronomy, and also serves as a useful desk reference for experts in the field. Key features: Contains a complete derivation of the pulsar timing response to gravitational waves, and the overlap reduction function for PTAs. Presents a comprehensive overview of source astrophysics, and the dynamical influences that shape the gravitational wave signals that PTAs are sensitive to. Serves as a detailed primer on gravitational-wave data analysis and numerical Bayesian techniques for PTAs.
