Scientific Cosmology and International Orders shows how scientific
ideas have transformed international politics since 1550. Allan
argues that cosmological concepts arising from Western science made
possible the shift from a sixteenth-century order premised upon
divine providence to the present order centred on economic growth.
As states and other international associations used scientific
ideas to solve problems, they slowly reconfigured ideas about how
the world works, humanity's place in the universe, and the meaning
of progress. The book demonstrates the rise of scientific ideas
across three cases: natural philosophy in balance of power
politics, 1550-1815; geology and Darwinism in British colonial
policy and international colonial orders, 1860-1950; and
cybernetic-systems thinking and economics in the World Bank and
American liberal order, 1945-2015. Together, the cases trace the
emergence of economic growth as a central end of states from its
origins in colonial doctrines of development and balance of power
thinking about improvement.
High time-resolution astrophysics (HTRA) involves measuring and
studying astronomical phenomena on timescales of seconds to
milliseconds. Although many areas of astronomy, such as X-ray
astronomy and pulsar observations, have traditionally required high
time-resolution studies, HTRA techniques are now being applied to
optical, infrared and gamma-ray wavelength regimes, due to the
development of high efficiency detectors and larger telescopes that
can gather photons at a higher rate. With lectures from eminent
scientists aimed at young researchers and postdoctorate students in
observational astronomy and astrophysics, this volume gives a
practical overview and introduction to the tools and techniques of
HTRA. Just as multi-spectral observations of astrophysical
phenomena are already yielding new scientific results, many
astronomers are optimistic that exploring the time domain will open
up an important new frontier in observational astronomy over the
next decade.
This book covers solar energy and the use of solar radiation in
connection with lighting. It provides a detailed introduction to
solar energy, photovoltaic (PV) solar energy conversion, and solar
lighting technologies, while also discussing all of these elements
in the context of the Balkan Peninsula. In the context of solar
energy, the book covers a range of elements, from the structure of
the sun, to PV solar plants. It subsequently addresses the status
quo of solar technologies in Bulgaria, Serbia and the Republika
Srpska and analyses the development of these technologies over the
years, including their economic status, and how these aspects have
shaped their current status. Undergraduate and graduate students,
researchers and professionals, particularly those based in the
Balkans, will find this book both informative and interesting.
This open access book serves as textbook on the physics of the
radiation belts surrounding the Earth. Discovered in 1958 the
famous Van Allen Radiation belts were among the first scientific
discoveries of the Space Age. Throughout the following decades the
belts have been under intensive investigation motivated by the
risks of radiation hazards they expose to electronics and humans on
spacecraft in the Earth's inner magnetosphere. This textbook
teaches the field from basic theory of particles and plasmas to
observations which culminated in the highly successful Van Allen
Probes Mission of NASA in 2012-2019. Using numerous data examples
the authors explain the relevant concepts and theoretical
background of the extremely complex radiation belt region, with the
emphasis on giving a comprehensive and coherent understanding of
physical processes affecting the dynamics of the belts. The target
audience are doctoral students and young researchers who wish to
learn about the physical processes underlying the acceleration,
transport and loss of the radiation belt particles in the
perspective of the state-of-the-art observations.
Astrobiology not only investigates how early life took hold of our
planet but also life on other planets - both in our Solar System
and beyond - and their potential for habitability. The book take
readers from the scars on planetary surfaces made by space rocks to
the history of the Solar System narrated by those space rocks as
well as exoplanets in other planetary systems. But the true
question is how life arose here or elsewhere. Modern comparative
genomics has revealed that Darwin was correct; a set of highly
conserved genes and cellular functions indicate that all life is
related by common ancestry. The Last Universal Common Ancestor or
LUCA sits at the base of the Tree of Life. However, once that life
took hold, it started to diversify and form complex microbial
communities that are known as microbial mats and stromatolites. Due
to their long evolutionary history and abundance on modern Earth,
research on the biological, chemical and geological processes of
stromatolite formation has provided important insights into the
field of astrobiology. Many of these microbialite-containing
ecosystems have been used as models for astrobiology, and NASA
mission analogs including Shark Bay, Pavilion and Kelly Lakes.
Modern microbialites represent natural laboratories to study
primordial ecosystems and provide proxies for how life could evolve
on other planets. However, few viral metagenomic studies (i.e.,
viromes) have been conducted in microbialites, which are not only
an important part of the community but also mirror its
biodiversity. This book focuses on particularly interesting sites
such as Andean lake microbialites, a proxy of early life since they
are characterized by very high UV light, while Alchichica and
Bacalar lakes are characterized by high-salt and oligotrophic
waters that nurture stromatolites. However, it is only the oasis of
Cuatro Cienegas Basin in Mexico that stored past life in its marine
sediments of the Sierra de San Marcos. This particular Sierra has a
magmatic pouch that moves the deep aquifer to the surface in a
cycle of sun drenched life and back to the depths of the magmatic
life in an ancient cycle that now is broken by the overexploitation
of the surface water as well as the deep aquifer in order to
irrigate alfalfa in the desert. The anthropocene, the era of human
folly, is killing this unique time machine and with it the memory
of the planet.
Analysis of the orbital motion of the Earth, the Moon and other
planets and their satellites led to the discovery that all bodies
in the Solar System are moving with the first cosmic velocity of
their proto parents. The mean orbital velocity of each planet is
equal to the first cosmic velocity of the Protosun, the radius of
which is equal to the semi-major axis of the planet s orbit. The
same applies for the planets satellites. All the small planets,
comets, other bodies and the Sun itself follow this law, a finding
that has also been proven by astronomical observations. The
theoretical solutions based on the Jacobi dynamics explain the
process of the system creation and decay, as well as the nature of
Kepler s laws.
This well-documented and fascinating book tells how, over the
centuries, a series of visionaries, scientists, technologists, and
politicians fostered the involvement of Italy in space exploration.
The lives of these pioneers was often far from easy, yet they
persevered. The fruits of their efforts can today be witnessed in
Italy's success within the cutting-edge space sector. Italy's
history in space started at the end of the fourteenth century and
continued with the development of fireworks. Later, the nineteenth
century marked the beginning of research into rockets in a more
scientific way. After World War II, rocket technology was advanced
with the aid of German scientists, and in the 1960s Luigi Broglio,
the father of Italian space exploration, designed the San Marco
satellite. In 1979 the first Italian Space Plan was launched, but
it was the foundation of the Italian Space Agency in 1988 that
kick-started a program of exploration in various fields of cosmic
research. The outcome was construction of the Vega launcher and
collaboration in the International Space Station. Now the Italian
space industry stands ready to play an important role in the
Gateway orbital station. All of this history, and more, is explored
in this riveting book.
The COSPAR Colloquium on Solar-Terrestrial Magnetic Activity and
Space Environment (STMASE) was held in the National Astronomy
Observatories of Chinese Academy of Sciences (NAOC) in Beijing,
China in September 10-12, 2001. The meeting was focused on five
areas of the solar-terrestrial magnetic activity and space
environment studies, including study on solar surface magnetism;
solar magnetic activity, dynamical response of the heliosphere;
space weather prediction; and space environment exploration and
monitoring. A hot topic of space research, CMEs, which are widely
believed to be the most important phenomenon of the space
environment, is discussed in many papers. Other papers show results
of observational and theoretical studies toward better
understanding of the complicated image of the magnetic coupling
between the Sun and the Earth, although little is still known
little its physical background. Space weather prediction, which is
very important for a modern society expanding into out-space, is
another hot topic of space research. However, a long way is still
to go to predict exactly when and where a disaster will happen in
the space. In that sense, there is much to do for space environment
exploration and monitoring. The manuscripts submitted to this
Monograph are divided into the following parts: (1) solar surface
magnetism, (2) solar magnetic activity, (3) dynamical response of
the heliosphere, (4) space environment exploration and monitoring;
and (5) space weather prediction. Papers presented in this meeting
but not submitted to this Monograph are listed by title as
unpublished papers at the end of this book.
In this, the first history of artifical satellites and their uses, Helen Gavaghan shows how the idea of putting an object in orbit around the earth changed from science fiction to indespensible technology in the twinkling of an eye. Thanks to satellites, we can now send data and images anywhere in the world in an instant. The satellite-based navigational system can pinpoint your exact location anywhere in the world; it is so precise that, from outer space, it can detect the sag on an airplane's wing. Focusing on three major areas of development - navigational satellites, communications, and weather observation and forecasting - Gavaghan tells the remarkable inside story of how obscure men and women, often laboring under strict secrecy, made the extraordinary scientific and technological discoveries needed to make these miracles happen. Written by a science journalist with support from the Sloane Foundation, the book describes the birth of the modern scientific era in the twentieth century, with creation of satellite technology. The narrative is part history - beginning with the Russian-U.S. contest with the launch of Sputnik; part politics, as scientists and visionary engineers compete for scarce funding that will bring their dreams to reality; partly the story of the singular and fascinating individuals who were present at the creation of our modern technological era.
An invaluable resource for working programmers, as well as a fount
of useful algorithmic tools for computer scientists, astronomers,
and other calendar enthusiasts, The Ultimate Edition updates and
expands the previous edition to achieve more accurate results and
present new calendar variants. The book now includes coverage of
Unix dates, Italian time, the Akan, Icelandic, Saudi Arabian Umm
al-Qura, and Babylonian calendars. There are also expanded
treatments of the observational Islamic and Hebrew calendars and
brief discussions of the Samaritan and Nepalese calendars. Several
of the astronomical functions have been rewritten to produce more
accurate results and to include calculations of moonrise and
moonset. The authors frame the calendars of the world in a
completely algorithmic form, allowing easy conversion among these
calendars and the determination of secular and religious holidays.
LISP code for all the algorithms is available in machine-readable
form.
This book introduces the modern field of 3+1 numerical relativity.
The book has been written in a way as to be as self-contained as
possible, and only assumes a basic knowledge of special relativity.
Starting from a brief introduction to general relativity, it
discusses the different concepts and tools necessary for the fully
consistent numerical simulation of relativistic astrophysical
systems, with strong and dynamical gravitational fields. Among the
topics discussed in detail are the following: the initial data
problem, hyperbolic reductions of the field equations, gauge
conditions, the evolution of black hole space-times, relativistic
hydrodynamics, gravitational wave extraction and numerical methods.
There is also a final chapter with examples of some simple
numerical space-times. The book is aimed at both graduate students
and researchers in physics and astrophysics, and at those
interested in relativistic astrophysics.
We have arrived at the third volume of this useful series on
Organiza tions and Strategies in Astronomy (OSA). It contains
seventeen articles on a wide range of topics, from virtual
observatories, astronomy organizations in various communities
(Czech Republic, Slovak Republic, South Africa), and the role of
ground stations in space observatories, to quality assurance in UK
higher education. In this foreword, I shall give some views on
ideas expressed in this volume, in particular from my personal
experience when I was project officer for the Canada-France-Hawaii
Telescope (CFHT). Let me first remind readers that present and
future astronomy is in creasingly dependent on high-level
management. Not everybody knows that the scheduling of the Hubble
Space Telescope is performed by a neural network software called
SPIKE, described in the stimulating workshop New Observing Modes
for the Next Centuryl, partly reported in OSA Volume II by 1.
Robson. New observing facilities, in space or on the ground, are so
complex that they need highly qualified engineers and rigorous
management procedures. Each observing hour on the Very Large
Telescope (VLT) fa cility is worth about EUR 7,000, including the
amortization of the capital expenses over 30 years. This does not
leave much room for amateurism, neither in the time allocation
procedures, nor in the daily telescope control.
For over 35 years, radio astronomical techniques have made an
impressive series of advances in our understanding of solar
phenomena. However, although the subject has been partially
discussed in "Paris Symposium on Radio Astronomy" in 1958,
NASA-GSFC Symposium on "Physics of Solar Flares" in 1963, and the
lAU Symposium No. 57 on "Coronal Disturbances" in 1973, there has
not been a major international meeting dedicated to "Radio Physics
of the Sun." This is the first major symposium on the subject held
under the auspices of the International Astronomical Union. It was
jointly spon sored by lAU Commission 40, Radio Astronomy, and by
lAU Commission 10, Solar Activity. It was also sponsored by the
Solar Physics Division of the American Astronomical Society. Thig
volume contains the proceedings of this meeting, lAU Symposium No.
86 on "Radio Physics of the Sun" that was held in College Park,
Maryland, August 7-10, 1979. The Scientific Organizing Committee of
the Symposium consisted of M. R. Kundu (chairman), G. A. Dulk, O.
Hachenberg, M. Kuperus, D. J. McLean, D. Melrose, M. Pick, J. L.
Steinberg, T. Takakura, A. Tlamicha and V. V. Zheleznyakov. The
topics and speakers were chosen in order to emphasize the current
observational material with particular reference to centi meter
wavelength observations of a few arc-second resolution, fast
two-dimensional pictures of the sun at meter-decameter wavelengths
and the recent advances in plasma and radiation theory."
Based on a Simons Symposium held in 2018, the proceedings in this
volume focus on the theoretical, numerical, and observational quest
for dark matter in the universe. Present ground-based and satellite
searches have so far severely constrained the long-proposed
theoretical models for dark matter. Nevertheless, there is
continuously growing astrophysical and cosmological evidence for
its existence. To address present and future developments in the
field, novel ideas, theories, and approaches are called for. The
symposium gathered together a new generation of experts pursuing
innovative, more complex theories of dark matter than previously
considered.This is being done hand in hand with experts in
numerical astrophysical simulations and observational
techniques-all paramount for deciphering the nature of dark matter.
The proceedings volume provides coverage of the most advanced stage
of understanding dark matter in various new frameworks. The
collection will be useful for graduate students, postdocs, and
investigators interested in cutting-edge research on one of the
biggest mysteries of our universe.
Traditionally, solar and stellar physics have been two separate
branches of astronomy, which independently of each other have
developed their own scientific goals and methods. During the last
decade, however, we have witnessed a gradual convergence of these
two areas: The solar physicists realize more and more that the sun
has to be seen as a special case in a large family of stars of
various properties. A more complete understanding of the sun can
only be achieved by considering it in this broader context. The
stellar physicists on the other hand have become aware that the
detailed knowledge of the physical processes that the solar
physicists have reached has a more general significance and can be
applied to a variety of other astrophysical objects. Observational
techniques developed in solar work can frequently be adapted for
other stars as well. This unified approach to solar and stellar
physics is often called the "solar-stellar connection". One main
goal of this approach has been to understand the general nature and
causes of stellar activity. The pioneering and visionary program to
search for activity cycles on other stars started by Olin Wilson at
the Mount Wilson Observatory 16 years ago has born fruit: in his
sample of 91 stars, cyclic behaviour similar to that of the sun is
found to be quite common, but many stars also show irregular
activity fluctua.tions of large amplitude.
Astrometry has historically been fundamental to all the fields of
astronomy, driving many revolutionary scientific results. ESA's
Gaia mission is astrometrically, photometrically and
spectroscopically surveying the full sky, measuring around a
billion stars to magnitude 20, to allow stellar distance and age
estimations with unprecedented accuracy. With the complement of
radial velocities, it will provide the full kinematic information
of these targets, while the photometric and spectroscopic data will
be used to classify objects and astrophysically characterize stars.
IAU Symposium 330 reviews the first 2.5 years of Gaia activities
and discusses the scientific results derived from the first Gaia
data release (GDR1). This significant increase in the precision of
the astrometric measurements has sharpened our view of the Milky
Way and the physical processes involved in stellar and galactic
evolution. To many, the Gaia revolution heralds a transformation
comparable to the impact of the telescope's invention four
centuries ago.
One of the most spectacular discoveries of molecular astronomy has
been the detection of maser emission. The same radiation that is
generated in the laboratory only with elaborate, special equipment
occurs naturally in interstellar space. This intense radiation
probes the smallest structures that can be studied with radio
telescopes. By a fortunate coincidence maser radiation is generated
in both star forming regions and the envelopes of late-type stars.
The early and late stages in the life of a star are considered to
be the most interesting phases of stellar evolution. Maser emission
has also been detected in external galaxies. This book provides an
extensive coverage of the interstellar maser phenomenon. A
precondition for maser action is departure from thermal
equilibrium. The book therefore starts with a detailed coverage of
the basic background concepts required for an understanding of line
formation and radiative transfer. It goes on to describe the
theoretical and phenomenological aspects of interstellar masers,
their formation sites and the inversion mechanisms. The book will
interest active researchers in astronomy and astrophysics as well
as in other areas of physics. It is suitable as a textbook in a
graduate course and will enable a graduate student to embark on
research projects in this exciting area in particular, and
molecular radio astronomy in general.
Leading specialists in various disciplines were first invited to
a multidisciplinary workshop funded by ICSU on the topic to gain a
better appreciation and perspective on the subject of
comet/asteroid impacts as viewed by different disciplines. This
volume provides a necessary link between various disciplines and
comet/asteroid impacts.
This book provides a systematic introduction to the observation and
application of kinetic Alfven waves (KAWs) in various plasma
environments, with a special focus on the solar-terrestrial
coupling system. Alfven waves are low-frequency and long-wavelength
fluctuations that pervade laboratory, space and cosmic plasmas.
KAWs are dispersive Alfven waves with a short wavelength comparable
to particle kinematic scales and hence can play important roles in
the energization and transport of plasma particles, the formation
of fine magneto-plasma structures, and the dissipation of turbulent
Alfven waves. Since the 1990s, experimental studies on KAWs in
laboratory and space plasmas have significantly advanced our
understanding of KAWs, making them an increasingly interesting
subject. Without a doubt, the solar-terrestrial coupling system
provides us with a unique natural laboratory for the comprehensive
study of KAWs. This book presents extensive observations of KAWs in
solar and heliospheric plasmas, as well as numerous applications of
KAWs in the solar-terrestrial coupling system, including solar
atmosphere heating, solarwind turbulence, solar wind-magnetosphere
interactions, and magnetosphere-ionosphere coupling. In addition,
for the sake of consistency, the book includes the basic theories
and physical properties of KAWs, as well as their experimental
demonstrations in laboratory plasmas. In closing, it discusses
possible applications of KAWs to other astrophysical plasmas.
Accordingly, the book covers all the major aspects of KAWs in a
coherent manner that will appeal to advanced graduate students and
researchers whose work involves laboratory, space and astrophysical
plasmas.
This edited volume discusses how even small nation states can make
a significant difference in the future of space governance. The
book is divided into three main sections covering political theory,
case studies, and space technology and applications. Key topics of
discussion include planetary defense, space mining, and high-power
systems in space. Through these timely subjects, the book presents
strategies for developing a truly global governance framework in
space, based on the concept of a responsible cosmopolitan state.
Authored by a multidisciplinary group of researchers from the Czech
Republic, the volume will appeal to other scientific teams and
policymakers looking to become pioneers of cosmopolitan space
policies at a national and global level.
Multiply charged ions have always been in the focus of atomic
physics, astrophysics, plasma physics, and theoretical physics.
Within the last few years, strong progress has been achieved in the
development of ion sources, ion storage rings, ion traps, and
methods to cool ions. As a consequence, nowadays, experiments with
ensembles of multiply charged ions of brilliant quality are
performed in many laboratories. The broad spectrum of the
experiments demonstrates that these ions are an extremely versatile
tool for investigations in pure and applied physics. It was the aim
of this ASI to bring together scientists working in different
fields of research with multiply charged ions in order to get an
overview of the state of the art, to sound out possibilities for
fruitful cooperations, and to discuss perspectives for the future.
Accordingly, the programme of the ASI reached from established
areas like QED calculations, weak interactions, x-ray astronomy,
x-ray lasers, multi photon excitation, heavy-ion induced fusion,
and ion-surface interactions up to the very recently opened areas
like bound-beta decay, laser and x-ray spectroscopy, and
spectrometry of ions in rings and traps, and the interaction of
highly charged ions with biological cells. Impressive progress in
nearly all of the fields could be reported during the meeting which
is documented by the contributions to this volume. The theoretical
understand ing of QED and correlation effects in few-electron heavy
ions is rapidly developing."
