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.
Translations of the Yi jing into western languages have been biased towards the yili ('meaning and pattern') tradition, whereas studies of the xiangshu ('image and number') tradition - which takes as its point of departure the imagery and numerology associated with divination and its hexagrams, trigrams, lines, and related charts and diagrams - has remained relatively unexplored. This major new reference work is organised as a Chinese-English encyclopedia, arranged alphabetically according to the pinyin romanisation, with Chinese characters appended. A character index as well as an English index is included. The entries are of two kinds: technical terms and various other concepts related to the 'image and number' tradition, and bio-bibliographical information on Chinese Yi jing scholars. Each entry in the former category has a brief explanation that includes references to the origins of the term, cross-references, and a reference to an entry giving a more comprehensive treatment of the subject.
From a star theoretical physicist, a journey into the world of
particle physics and the cosmos -- and a call for a more just
practice of science. In The Disordered Cosmos, Dr. Chanda
Prescod-Weinstein shares her love for physics, from the Standard
Model of Particle Physics and what lies beyond it, to the physics
of melanin in skin, to the latest theories of dark matter -- all
with a new spin informed by history, politics, and the wisdom of
Star Trek. One of the leading physicists of her generation, Dr.
Chanda Prescod-Weinstein is also one of fewer than one hundred
Black American women to earn a PhD from a department of physics.
Her vision of the cosmos is vibrant, buoyantly non-traditional, and
grounded in Black feminist traditions. Prescod-Weinstein urges us
to recognize how science, like most fields, is rife with racism,
sexism, and other dehumanizing systems. She lays out a bold new
approach to science and society that begins with the belief that we
all have a fundamental right to know and love the night sky. The
Disordered Cosmos dreams into existence a world that allows
everyone to experience and understand the wonders of the universe.
The previous Saas-Fee Advanced Course dedicated to the interstellar
medium took place in 1972. The tremendous scientific advances that
have occurred in this field since then, in particular owing to the
availabihty of receivers working at completely unexplored
wavelength bands, fuUy justified a new set of lectures. As a
consequence, the members of the Swiss Society for Astrophysics and
As tronomy voted that "The Galactic Interstellar Medium" should be
the subject of the 1991 course. The 21st Saas Fee Advanced Course
took place in Les Diablerets from 18 to 23 March 1991, gathering
together about 80 participants from all over the world, but mostly
from Europe. According to a rule that has proved to lead to
success, but also to chal lenge the lecturers' energy, the format
of a Saas-Fee Advanced Course consists traditionally of 28 lectures
of 45 minutes which take place in the morning and late afternoon,
leaving ample time for discussions, self-study, hiking or skiing.
Despite the inordinate work load imposed, this year's lecturers
felt that the subject was sufficiently dense to increase the
lecture time by 1/3! This proved judicious and left more time for
questions and discussions during the lectures.
The Short Story of the Universe is a new introduction to the
subject of the universe. Covering 130 key components that make it
up - from dwarf galaxies and spiral arms to red giants and the
planets of the solar sytem - and linking these to the universe's
structure and the theories that help us understand it, this book
simplifies this riveting yet mind-boggling subject, telling the
story of how it came into being and how it will eventually be no
more. Accessible and concise, generously illustrated throughout,
and with all the essential information presented without jargon,
readers are given all the tools they need to enjoy the fascinating
history of the deepest depths of the universe.
Dynamical systems theory is especially well-suited for determining
the possible asymptotic states (at both early and late times) of
cosmological models, particularly when the governing equations are
a finite system of autonomous ordinary differential equations. In
this book we discuss cosmological models as dynamical systems, with
particular emphasis on applications in the early Universe. We point
out the important role of self-similar models. We review the
asymptotic properties of spatially homogeneous perfect fluid models
in general relativity. We then discuss results concerning scalar
field models with an exponential potential (both with and without
barotropic matter). Finally, we discuss the dynamical properties of
cosmological models derived from the string effective action. This
book is a valuable source for all graduate students and
professional astronomers who are interested in modern developments
in cosmology.
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.
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.

This manuscript, Mortal Grounding, has a simple thought in mind. To
bring together our modern cosmological knowledge with our
understanding of what is consciousness. It is something of a task
to unite these two styles of comprehension about our existence, as
much as it is to join quantum physics with general and special
relativity. The idea is that both want to reach the source, the
source of what is cosmological and what is consciousness. It seems
simple enough. Cosmology studies the creation, searching for the
creator of it all, whatever that may be. Consciousness seems to
look more at what is the creator in order to understand creation.
They are parallel and reversed, but both seek to understand,
re-link, comprehend or unite with the Mystery. This Universe's
Given Moment of reaching, of conscious mortal becoming, grounded on
Earth, for the brief moment, life to death, yet in and as a rare
something more, the rarest star stuff circling back as
consciousness that is able to grasp its origin, without a direction
transposed as time's beginning. This would be one idea of mortal
grounding. Some of the subjects taken up in this endeavor of
unification are Pure Gravity, Spacetime Fluid, the Superclustering
of Universes, Wave Cosmology, Non-Local Independent Consciousness,
the question, is this Logical or Mystical. The text also leans
heavily on Tantra's explanations, examining the myriad layers of
consciousness and their psychological weight, the intriguing erotic
energy, the hidden secrets that are rarely discussed and the nature
of freedom according to the belief system of Tantra.

This book describes some of the frontier problems of cosmology: our
almost total ignorance of what the Universe is made up of, the
mystery of its origin and its end. The book starts with a
description of the historical events that led to the construction
of the Big Bang model together with the stages that transformed the
Universe from a very hot place to a very cold one, full with the
structures that we observe today. These structures (stars,
galaxies, etc.) constitute only 5% of the contents of the Universe.
Concerning the remaining 95%, dubbed dark matter and dark energy,
we know very little, and we have only indirect evidence of their
existence. The text describes the story and the protagonists who
showed the need for the existence of this 'missing matter', the
observations, and puzzles they had to solve to understand that dark
matter was not ordinary matter. The book describes the hunt for
dark matter, carried out with instruments operating in space, on
the Earth's surface, and in laboratories built in the bowels of the
Earth. It also describes dark energy, which manifests itself in the
accelerated expansion of the Universe, and appeared only a few
billions of years ago. The book discusses why dark energy must
exist and what its existence implies, especially for the future and
the end of our Universe.
This fourth edition of Boerner´s The Early Universe is practically a new book, not just an updated version. In particular, to meet the wishes of many readers, it is now organized so as to make it more useful as a textbook. Problem sections are appended, too. In the center are the connections between particle physics and cosmology: the standard model, some basic implications of quantum field theory, and the questions of structure formation. A special feature of the book is the comparison of theoretical predictions with observations, separating "facts from fiction". Special emphasis is given to the observed anisotropies of the cosmic microwave background and the consequences drawn for cosmology and for the structure formation models. Nuclear and particle physicists and astrophysicists, researchers and teachers as well as graduate students will welcome this new edition of a classic text and reference.
This volume takes up the idea of 'multiplicity' as a new common
ground for international theory, bringing together 10 scholars to
reflect on the implications of societal multiplicity for areas as
diverse as nationalism, ecology, architecture, monetary systems,
cosmology and the history of political ideas. International
relations (IR), it is often said, has contributed no big ideas to
the interdisciplinary conversation of the social sciences and
humanities. Yet this is an unnecessary silence, for IR uniquely
addresses a fundamental fact about the human world: its division
into a multiplicity of interacting social formations. This feature
is full of consequences for the very nature of societies and for
social phenomena of all kinds. And in recent years a research
programme has emerged within IR to theorise these 'consequences of
multiplicity' and to trace how the effects of the international
dimension extend into other fields of social life. This book is a
powerful indication of the contribution that IR may yet make to the
human disciplines. The chapters in this book were originally
published as a special issue of Globalizations.
This volume provides a comprehensive and coherent introduction to
modern quantum cosmology - the study of the universe as a whole
according to the laws of quantum mechanics. In particular, it
presents a useful survey of the many profound consequences of
supersymmetry (supergravity) in quantum cosmology. After a general
introduction to quantum cosmology, the reader is led through
Hamiltonian supergravity and canonical quantization and quantum
amplitudes through to models of supersymmetric mini superspace and
quantum wormholes. The book is rounded off with a look at exciting
further developments, including the possible finiteness of
supergravity. Ample introductory material is included, ensuring
this topical volume is well suited as a graduate text. Researchers
in theoretical and mathematical physics, applied maths and
cosmology will also find it of immediate interest.
