Our Universe is amazing. This is its story, told in simple
language. The story tells how the Universe came to be what it is
today. It starts with the Big Bang and describes how stars, black
holes, and our solar system developed. It explores the evolution of
life on Earth and investigates the possibility of extra-terrestrial
life. It peers into the future and wonders about the Universe's
likely old age and death, or whatever else may be its end. The
challenge the book takes up is to explain all of this, including
some of the astonishing concepts we have in science, such as
Einstein's theories of Relativity and Quantum Mechanics, using
virtually no mathematics and without dumbing-down. All are
described narratively and explained using examples and anecdotes.
The book is written for young people with a thirst for learning
about the science of space, as well as for 'grown-ups' who want a
better understanding of this fascinating subject.
In On Both Sides of the Strait of Gibraltar Julio Samso studies the
history of medieval astronomy in al-Andalus (Muslim Spain), the
Maghrib and the Christian kingdoms of the Iberian Peninsula. He
proves that the Arabic, Latin, Hebrew, Castilian and Catalan
sources belong to the same tradition whose origin can be dated in
the 11th century due to the changes in Ptolemy's astronomical
theory introduced by the Toledan astronomer Ibn
al-Zarqalluh/Azarquiel. The book also analyses the role of
al-Andalus and the Iberian Peninsula in the transmission of Islamic
astronomy to Europe and justifies the fact that Eastern Islamic
works published after ca. 950 CE were not accessible to medieval
European scholars because they had not reached al-Andalus.
Visual Astronomy introduces the basics of observational astronomy,
a fundamentally limitless opportunity to learn about the universe
with your unaided eyes or with tools such as binoculars,
telescopes, or cameras.
Ensuring a Sustainable World
We are on the cusp of a 21st century Age of Discovery - about the
Earth, about the solar system, about ourselves and our place in the
cosmos - with new opportunities to address age-old challenges, as
well as to meet emerging ones. While advancing into space is not
the answer to these challenges, it can be a significant and vital
part of an answer, providing benefits that other answers cannot.
With a thoughtful program of space activities we can ensure a
sustainable world with abundant energy and resources, a high
standard of living, and unprecedented opportunity for all. However,
to become a widely held vision that we must pursue now, rather than
just interesting ideas for some distant time, we need to see space
as integral to addressing societal issues. This book shows a way to
do that.
There are abundant opportunities in space, but the only way to
utilize them is to go there. As our ancestors crossed thresholds to
inhabit the Earth, we can cross the threshold to become a
space-faring civilization, and realize the benefits of those
efforts. Space is only 100 km (62 miles) away, you just need to
look up.
What people are saying:
"Crossing the Threshold is a carefully considered, insightful
narrative that should interest anyone and everyone who cares about
the future of spaceflight." - Homer Hickam, author of Rocket
Boys/October Sky
"Crossing the Threshold is a NASA veteran's thoughtful and
considered look at the value of space travel and exploration, not
only for satisfying humanity's seemingly unquenchable thirst for
adventure and knowledge but also for preparing and positioning us
technically to begin to solve some of the greatest problems facing
us on Earth." - Henry Petroski, Aleksandar S. Vesic Professor of
Civil Engineering and Professor of History, Duke University, author
of The Essential Engineer: Why Science Alone Will Not Solve Our
Global Problems
Crossing the Threshold "is very impressive for the range of ideas
and technical specifics." - Felix Godwin, author of The Exploration
of the Solar System.
A glass is disordered material like a viscous liquid and behaves
mechanically like a solid. A glass is normally formed by
supercooling the viscous liquid fast enough to avoid
crystallization, and the liquid-glass transition occurs in diverse
manners depending on the materials, their history, and the
supercooling processes, among other factors. The glass transition
in colloids, molecular systems, and polymers is studied worldwide.
This book presents a unified theory of the liquid-glass transition
on the basis of the two band model from statistical quantum field
theory associated with the temperature Green's function method. It
is firmly original in its approach and will be of interest to
researchers and students specializing in the glass transition
across the physical sciences.
Structure and Evolution of Single Stars: An introduction is
intended for upper-level undergraduates and beginning graduates
with a background in physics. Following a brief overview of the
background observational material, the basic equations describing
the structure and evolution of single stars are derived. The
relevant physical processes, which include the equation of state,
opacity, nuclear reactions and neutrino losses are then reviewed.
Subsequent chapters describe the evolution of low-mass stars from
formation to the final white dwarf phase. The final chapter deals
with the evolution of massive stars.
Stonehenge was not an observatory used by druidical
astronomer-priests. It was, instead, a monument in which the moon
and the sun and the dead were joined together. In this book the
author explains how people in the British Isles, four thousand or
more years ago, identified life and death with the cycle of
midwinter and midsummer and with the risings and settings of the
sun and moon. This is why so many megalithic monuments have
astronomical sightlines built into them. This book describes how
astronomical customs developed in the British Isles. Unlike other
works about 'megalithic astronomy' technical explanations about
azimuths and declinations are kept to their simplest. The emphasis
here is upon people rather than pertrubations and eclipses.
Join the crew of space shuttle Enterprise as they prepare to take
the first step into the twenty-first century. Step aboard the
world's first reusable space vehicle with science writer Robert M.
Powers for a cockpit view of a launch, orbit, re-entry, and return
to earth. Preview the scheduled NASA shuttle missions in hundreds
of line drawings and photographs of the crew at work in orbit. The
shuttle system is the key to unlocking the next era of technology
and the forerunner of space transportation systems of tomorrow: The
world's first spaceship, the Enterprise, is here!
The diverse planetary environments in the solar system react in
somewhat different ways to the encompassing influence of the Sun.
These different interactions define the electrostatic phenomena
that take place on and near planetary surfaces. The desire to
understand the electrostatic environments of planetary surfaces
goes beyond scientific inquiry. These environments have enormous
implications for both human and robotic exploration of the solar
system. This book describes in some detail what is known about the
electrostatic environment of the solar system from early and
current experiments on Earth as well as what is being learned from
the instrumentation on the space exploration missions (NASA,
European Space Agency, and the Japanese Space Agency) of the last
few decades. It begins with a brief review of the basic principles
of electrostatics.
Following one of the most inspiring and fascinating stories linked
to the Royal Observatory, Greenwich, this book centres on the life
and achievements of John Harrison - designer and builder of the
first accurate marine chronometers. Inspired by the official prize
offered in 1714 to anyone who could solve the problem of finding
longitudinal position at sea, Harrison produced his four famous 'H'
timepieces. In doing so, he helped revolutionise sea travel, saving
many thousands of lives. John Harrison and the Quest for Longitude
is the intriguing account of one man driven by the need to solve
one of the greatest practical problems of his time.
The history of cosmology is often understood in terms of the
development of modern science, but Asian cosmological thought and
practice touched on many aspects of life, including mathematics,
astronomy, politics, philosophy, religion, and art. Because of the
deep pervasion of cosmology in culture, many opportunities arose
for transmissions of cosmological ideas across borders and
innovations of knowledge and application in new contexts. Taking a
wider view, one finds that cosmological ideas traveled widely and
intermingled freely, being frequently reinterpreted by scholars,
ritualists, and artists and transforming as they overlapped with
ideas and practices from other traditions. This book brings
together ten diverse scholars to present their views on these
overlapping cosmologies in Asia. They are Ryuji Hiraoka, Satomi
Hiyama, Eric Huntington, Yoichi Isahaya, Catherine Jami, Bill M.
Mak, D. Max Moerman, Adrian C. Pirtea, John Steele, and Dror Weil.
