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.
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.
This book argues that while the historiography of the development
of scientific ideas has for some time acknowledged the important
influences of socio-cultural and material contexts, the significant
impact of traumatic events, life threatening illnesses and other
psychotropic stimuli on the development of scientific thought may
not have been fully recognised. Howard Carlton examines the
available primary sources which provide insight into the lives of a
number of nineteenth-century astronomers, theologians and
physicists to study the complex interactions within their
'biocultural' brain-body systems which drove parallel changes of
perspective in theology, metaphysics, and cosmology. In doing so,
he also explores three topics of great scientific interest during
this period: the question of the possible existence of life on
other planets; the deployment of the nebular hypothesis as a theory
of cosmogony; and the religiously charged debates about the ages of
the earth and sun. From this body of evidence we gain a greater
understanding of the underlying phenomena which actuated
intellectual developments in the past and which are still relevant
to today's knowledge-making processes.
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.
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.

NASA SP-2011-4234. This book presents the history of planetary
protection by tracing the responses to the concerns on NASA's
missions to the Moon, Mars, Venus, Jupiter, Saturn, and many
smaller bodies of our solar system. The book relates the extensive
efforts put forth by NASA to plan operations and prepare space
vehicles that return exemplary science without contaminating the
biospheres of other worlds or our own. To protect irreplaceable
environments, NASA has committed to conducting space exploration in
a manner that is protective of the bodies visited, as well as of
our own planet.
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.
