The Ptolemaic system of the universe, with the earth at the center,
had held sway since antiquity as authoritative in philosophy,
science, and church teaching. Following his observations of the
heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the
geocentric system for a heliocentric model, with the sun at the
center. His remarkable work, On the Revolutions of Heavenly
Spheres, stands as one of the greatest intellectual revolutions of
all time, and profoundly influenced, among others, Galileo and Sir
Isaac Newton.
The year is 2007, the fiftieth anniversary of the Space Age. Space
shuttle Discovery is about o dock at the first permanent U. S.
space station, which author Dick Lattimer called Friendship. In all
but name, the space station depicted in these pages is based on
NASA plans. To help you project yourself on board, Lattimer has
created a fictional crew, including three rookie crew
members-doctoral candidates who have been chosen to do special work
on their theses. By viewing the space station through their eyes,
you'll learn about the important work to be done there. Friendship
reflects existing technology and projected plans. As part of his
extensive research, Lattimer, along with his son, illustrator
Michael Lattimer, had the unique opportunity to spend several
different days aboard the space station mockup at Huntsville,
Alabama. Inevitably, there will be design modification. But life
aboard out first permanent space station will probably resemble
life on space station Friendship. In these pages you'll v
Time, it has been said, is the enemy. In an era of harried lives,
time seems increasingly precious as hours and days telescope and
our lives often seem to be flitting past. And yet, at other times,
the minutes drag on, each tick of the clock excruciatingly drawn
out. What explains this seeming paradox? Based upon a full decade's
empirical research, Michael G. Flaherty's new book offers
remarkable insights on this most universal human experience.
Flaherty surveys hundreds of individuals of all ages in an attempt
to ascertain how such phenomena as suffering, violence, danger,
boredom, exhilaration, concentration, shock, and novelty influence
our perception of time. Their stories make for intriguing reading,
by turns familiar and exotic, mundane and dramatic, horrific and
funny. A qualitative and quantitative tour de force, A Watched Pot
presents what may well be the first fully integrated theory of time
and will be of interest to scientists, humanists, social scientists
and the educated public alike. A Choice Outstanding Academic Book.
An adventure in scientific discovery Pluto, the farthermost planet
in the solar system, some 3,673 million mites from the Sun, was
discovered by Clyde Tombaugh at the Lowell Observatory in 1930. The
fiftieth anniversary of Pluto's discovery will be celebrated in
1980 and OUT OF THE DARKNESS: THE PLANET PLUTO tells the exciting
scientific story of the twenty-five year search for a planet X
beyond Neptune, and its discovery-the only planet found in the
twentieth century. The planets Mercury, Venus. Mars, Jupiter, and
Saturn were all known since antiquity. Then Sir William Herschel
discovered Uranus in 1781, and 65 years later, in 1846, Johann
Calle and Urbain le Verner discovered Neptune. Variations in
orbital perturbations of the planets and theoretical astronomy were
responsible for predicting and discovering the three outermost
planets (Uranus, Neptune, and Pluto) and so Pluto's story is also,
to some extent, the story of its planetary neighbors. What kind of
world is Pluto? Much is still a mystery (its
This book describes how and why the early modern period witnessed
the marginalisation of astrology in Western natural philosophy, and
the re-adoption of the cosmological view of the existence of a
plurality of worlds in the universe, allowing the possibility of
extraterrestrial life. Founded in the mid-1990s, the discipline of
astrobiology combines the search for extraterrestrial life with the
study of terrestrial biology - especially its origins, its
evolution and its presence in extreme environments. This book
offers a history of astrobiology's attempts to understand the
nature of life in a larger cosmological context. Specifically, it
describes the shift of early modern cosmology from a paradigm of
celestial influence to one of celestial inhabitation. Although
these trends are regarded as consequences of Copernican cosmology,
and hallmarks of a modern world view, they are usually addressed
separately in the historical literature. Unlike others, this book
takes a broad approach that examines the relationship of the two.
From Influence to Inhabitation will benefit both historians of
astrology and historians of the extraterrestrial life debate, an
audience which includes researchers and advanced students studying
the history and philosophy of astrobiology. It will also appeal to
historians of natural philosophy, science, astronomy and theology
in the early modern period.
This thesis focuses on the very high Mach number shock wave that is
located sunward of Saturn's strong magnetic field in the continuous
high-speed flow of charged particles from the Sun (the solar wind).
The author exploits the fact that the Cassini spacecraft is the
only orbiter in a unique parameter regime, far different from the
more familiar near-Earth space, to provide in-situ insights into
the unreachable exotic regime of supernova remnants. This thesis
bridges the gap between shock physics in the Solar System and the
physics of ultra-high Mach number shocks around the remnants of
supernova explosions, since to date research into the latter has
been restricted to theory, remote observations, and simulations.
The authors of this volume have been intimately connected with the conception of Big Bang model since 1947. They present a picture of what is now believed to be state-of-the-art knowledge about the evolution of the expanding universe and delineate the story of the development of the Big Bang model as they have seen and lived it from their own unique vantage point.
In his PhD dissertation Martin Bo Nielsen performs observational
studies of rotation in stars like the Sun. The interior rotation in
stars is thought to be one of the driving mechanisms of stellar
magnetic activity, but until now this mechanism was unconstrained
by observational data. NASA's Kepler space mission provides
high-precision observations of Sun-like stars which allow rotation
to be inferred using two independent methods: asteroseismology
measures the rotation of the stellar interior, while the brightness
variability caused by features on the stellar surface trace the
rotation of its outermost layers. By combining these two techniques
Martin Bo Nielsen was able to place upper limits on the variation
of rotation with depth in five Sun-like stars. These results
suggest that the interior of other Sun-like stars also rotate in
much the same way as our own Sun.
This monograph traces the development of our understanding of how
and where energetic particles are accelerated in the heliosphere
and how they may reach the Earth. Detailed data sets are presented
which address these topics. The bulk of the observations are from
spacecraft in or near the ecliptic plane. It is timely to present
this subject now that Voyager-1 has entered the true interstellar
medium. Since it seems unlikely that there will be a follow-on to
the Voyager programme any time soon, the data we already have
regarding the outer heliosphere are not going to be enhanced for at
least 40 years.
NASA Gemini Owners' Workshop Manual 1965-1966 (all missions, all
models) An insight into NASA's Gemini spacecraft, the precursor to
Apollo and the key to the Moon David Woods and David M. Harland
NASA's Gemini space flight programme followed on from the
pioneering Mercury missions which put the first US astronauts into
space. The Gemini spacecraft was an agile flying machine for
fighter pilots, which gave the US the tool it needed to fly into
space, and in doing so prepared NASA to travel to the Moon. In a
breathless series of 10 manned flights spread across only 20 months
of 1965 and 1966, Gemini propelled NASA from being a tentative,
inexperienced space agency to a tough, competent and confident
organisation that could send astronauts to another world. This
Manual celebrates this important spacecraft with a thorough look at
the technologies and techniques that were developed for the
programme during its heyday.
This thesis describes the physics and computational aspects of an
end-to-end simulator to predict the performance of a Space-based
Far Infrared Interferometer. The present thesis also includes, the
science capabilities and instrumental state-of-the art. The latter
is the ambitious next step which the Far-Infrared Astrophysical
community needs to take to improve in anyway on the results of the
most recent and current space telescopes in this wavelength region.
This thesis outlines the requirements involved in such a mission
and describes the most promising technique to capture most of the
astrophysical information by combining spectroscopy to spatial
interferometer. The simulation of such a system is extremely
complex requiring multiple Fourier transforms each of which is
subject to instrument non-idealities and appropriate optimization
techniques. As a conclusion, the thesis provides an example of the
basic performance achievable with such an instrument when targeting
a young star formation region.
This book addresses a variety of topics within the growing
discipline of Archaeoastronomy, focusing especially on
Archaeoastronomy in Sicily and the Mediterranean and Cultural
Astronomy. A further priority is discussion of the astronomical and
statistical methods used today to ascertain the degree of
reliability of the chronological and cultural definition of sites
and artifacts of archaeoastronomical interest. The contributions
were all delivered at the XVth Congress of the Italian Society of
Archaeoastronomy (SIA), held under the rubric "The Light, the
Stones and the Sacred" - a theme inspired by the International Year
of Light 2015, organized by UNESCO. The full meaning of many
ancient monuments can only be understood by examining their
relation to light, given the effects that light radiation produces
in "interacting" with lithic structures. Moreover, in addition to
manifestations of the sacred through the medium of light
(hierophanies), there are many ties between temples, tombs,
megalithic structures, and the architecture of almost all ages and
cultures and our star, the Sun. Readers will find the book to be a
source of fascinating insights based on synergies between the
disciplines of archaeology and astronomy.
This book uses new data from the very low radio frequency telescope
LOFAR to analyse the magnetic structure in the giant radio galaxy
NGC6251. This analysis reveals that the magnetic field strength in
the locality of this giant radio galaxy is an order of magnitude
lower than in other comparable systems. Due to the observational
limitations associated with capturing such huge astrophysical
structures, giant radio galaxies are historically a poorly sampled
population of objects; however, their preferential placement in the
more rarefied regions of the cosmic web makes them a uniquely
important probe of large-scale structures. In particular, the
polarisation of the radio emissions from giant radio galaxies is
one of the few tools available to us that can be used to measure
magnetic fields in regions where the strength of those fields is a
key differentiator for competing models of the origin of cosmic
magnetism. Low frequency polarisation data are crucial for detailed
analyses of magnetic structure, but they are also the most
challenging type of observational data to work with. This book
presents a beautifully coupled description of the technical and
scientific analysis required to extract valuable information from
such data and, as the new generation of low frequency radio
telescopes reveals the larger population of giant radio galaxies,
it offers a significant resource for future analyses.
This thesis presents a pioneering method for gleaning the maximum
information from the deepest images of the far-infrared universe
obtained with the Herschel satellite, reaching galaxies fainter by
an order of magnitude than in previous studies. Using these
high-quality measurements, the author first demonstrates that the
vast majority of galaxy star formation did not take place in
merger-driven starbursts over 90% of the history of the universe,
which suggests that galaxy growth is instead dominated by a steady
infall of matter. The author further demonstrates that massive
galaxies suffer a gradual decline in their star formation activity,
providing an alternative path for galaxies to stop star formation.
One of the key unsolved questions in astrophysics is how galaxies
acquired their mass in the course of cosmic time. In the standard
theory, the merging of galaxies plays a major role in forming new
stars. Then, old galaxies abruptly stop forming stars through an
unknown process. Investigating this theory requires an unbiased
measure of the star formation intensity of galaxies, which has been
unavailable due to the dust obscuration of stellar light.
Of Clocks and Time takes readers on a five-stop journey through the
physics and technology (and occasional bits of applications and
history) of timekeeping. On the way, conceptual vistas and
qualitative images abound, but since mathematics is spoken
everywhere the book visits equations, quantitative relations, and
rigorous definitions are offered as well. The expedition begins
with a discussion of the rhythms produced by the daily and annual
motion of sun, moon, planets, and stars. Centuries worth of
observation and thinking culminate in Newton's penetrating
theoretical insights since his notion of space and time are still
influential today. During the following two legs of the trip, tools
are being examined that allow us to measure hours and minutes and
then, with ever growing precision, the tiniest fractions of a
second. When the pace of travel approaches the ultimate speed
limit, the speed of light, time and space exhibit strange and
counter-intuitive traits. On this fourth stage of the journey,
Einstein is the local tour guide whose special and general theories
of relativity explain the behavior of clocks under these
circumstances. Finally, the last part of the voyage reverses
direction, moving ever deeper into the past to explore how we can
tell the age of "things" - including that of the universe itself.
In contrast to other publications this work discusses Nanoscience
strictly at the ultimate level where the properties of atomic
matter emerge. The renowned author presents an interdisciplinary
approach leading to the forefront of research of
quantum-theoretical aspects of time, selforganizing nanoprocesses,
brain functions, the matter-mind problem, behaviour research and
philosophical questions.
This book comprises a fascinating collection of contributions on
the Merz telescopes in Italy that collectively offer the first
survey on historical large refracting telescopes in the country,
drawing on original documents and photographs. It opens with a
general introduction on the importance of Merz telescopes in the
history of astronomy and analyses of the local and international
contexts in which the telescopes were made. After examination of an
example of the interaction between the maker and the astronomer in
the construction and maintenance of these refractors, the history
of the Merz telescopes at the main Italian observatories in the
nineteenth century is described in detail. Expert testimony is also
provided on how these telescopes were successfully used until the
second half of the twentieth century for research purposes, thus
proving their excellent optical qualities.
Origins of the Earth, Moon, and Life: An Interdisciplinary Approach
presents state-of-the-art knowledge that is based on theories,
experiments, observations, calculations, and analytical data from
five astro-sciences, astronomy, astrobiology, astrogeology,
astrophysics, and cosmochemistry. Beginning with the origin of
elements, and moving on to cover the formation of the early Solar
System, the giant impact model of the Earth and Moon, the oldest
records of life, and the possibility of life on other planets in
the Solar System, this interdisciplinary reference provides a
complex understanding of the planets and the formation of life.
Synthesizing concepts from all branches of astro-sciences into one,
the book is a valuable reference for researchers in astrogeology,
astrophysics, cosmochemistry, astrobiology, astronomy, and other
space science fields, helping users better understand the
intersection of these sciences.
