The book focuses on the study of the temporal behavior of complex
many-particle systems. The phenomenon of time and its role in the
temporal evolution of complex systems is a remaining mystery. The
book presents the necessity of the interdisciplinary point of view
regarding on the phenomenon of time.The aim of the present study is
to summarize and formulate in a concise but clear form the trends
and approaches to the concept of time from a broad
interdisciplinary perspective exposing tersely the complementary
approaches and theories of time in the context of thermodynamics,
statistical physics, cosmology, theory of information, biology and
biophysics, including the problem of time and aging. Various
approaches to the problem show that time is an extraordinarily
interdisciplinary and multifaceted underlying notion which plays an
extremely important role in various natural complex processes.
What does it take to consider a planet potentially habitable? If a
planet is suitable for life, could life be present? Is life on
other planets inevitable? Searching for Habitable Worlds answers
these questions and provides both the general public and astronomy
enthusiasts with a richly illustrated discussion of the most
current knowledge regarding the search for extrasolar planets.
Nearly everyone wants to know if we are alone in the universe. This
book might not have the answers, but shows where we should look.
This book is a fun and accessible book for everyone from middle
schoolers to amateur astronomers of all ages. The use of
non-technical language and abundant illustrations make this a quick
read to inform everyone about the latest movement in the search for
other planets that we might be able to inhabit. After a brief
discussion on why humans are hard-wired to be curious, and to
explore the unknown, the book describes what extrasolar planets
are, how to detect them, and how to pin down potential targets. In
addition, a data-driven list of the best candidates for
habitability is profiled and the next generation of
exoplanet-hunting scientific instruments and probes are identified.
On Earth, lakes provide favorable environments for the development
of life and its preservation as fossils. They are extremely
sensitive to climate fluctuations and to conditions within their
watersheds. As such, lakes are unique markers of the impact of
environmental changes. Past and current missions have now
demonstrated that water once flowed at the surface of Mars early in
its history. Evidence of ancient ponding has been uncovered at
scales ranging from a few kilometers to possibly that of the Arctic
ocean. Whether life existed on Mars is still unknown; upcoming
missions may find critical evidence to address this question in
ancient lakebeds as clues about Mars' climate evolution and its
habitability potential are still preserved in their sedimentary
record. Lakes on Mars is the first review on this subject. It is
written by leading planetary scientists who have dedicated their
careers to searching and exploring the questions of water, lakes,
and oceans on Mars through their involvement in planetary
exploration, and the analysis of orbital and ground data beginning
with Viking up to the most recent missions. In thirteen chapters,
Lakes on Mars critically discusses new data and explores the role
that water played in the evolution of the surface of Mars, the past
hydrological provinces of the planet, the possibility of heated
lake habitats through enhanced geothermal flux associated with
volcanic activity and impact cratering. The book also explores
alternate hypotheses to explain the geological record. Topographic,
morphologic, stratigraphic, and mineralogic evidence are presented
that suggest successions of ancient lake environments in Valles
Marineris and Hellas. The existence of large lakes and/or small
oceans in Elysium and the Northern Plains is supported both by the
global distribution of deltaic deposits and by equipotential
surfaces that may reflect their past margins. Whether those
environments were conducive to life has yet to be demonstrated but
from comparison with our planet, their sedimentary deposits may
provide the best opportunity to find its record, if any. The final
chapters explore the impact of climate variability on declining
lake habitats in one of the closest terrestrial analogs to Mars at
the Noachian/Hesperian transition, identify the geologic,
morphologic and mineralogic signatures of ancient lakes to be
searched for on Mars, and present the case for landing the Mars
Science Laboratory mission in such an environment.
The study of dark matter, in both astrophysics and particle
physics, has emerged as one of the most active and exciting topics
of research in recent years. This book reviews the history behind
the discovery of missing mass (or unseen mass) in the Universe, and
ties this into the proposed extensions to the Standard Model of
Particle Physics (such as Supersymmetry), which were being proposed
within the same time frame. This book is written as an introduction
to these problems at the forefront of astrophysics and particle
physics, with the goal of conveying the physics of dark matter to
beginning undergraduate majors in scientific fields. The book goes
onto describe existing and upcoming experiments and techniques,
which will be used to detect dark matter either directly on
indirectly.
The universe is pervaded by particles with extreme energies,
millions of times greater than we can produce on Earth. They have
been a mystery for over a century. Now, current and future
experiments in particle astrophysics are leading us to answers to
the most fundamental questions about them. How does nature
accelerate the highest energy particles in the universe? Do new
interactions between them occur at such extreme energies? Are there
unknown aspects of spacetime that can be uncovered by studying
these particles?This book brings together three fields within
'extreme astronomy': ultra-high-energy cosmic ray physics, neutrino
astronomy, and gamma-ray astronomy, and discusses how each can help
answer these questions. Each field is presented with a theoretical
introduction that clearly elucidates the key questions scientists
face. This is followed by chapters that discuss the current set of
experiments - how they work and their discoveries. Finally, new
techniques and approaches are discussed to solve the mysteries
uncovered by the current experiments.
Does science deny God? Did the Universe and life appear by chance
or is there evidence of a bigger scheme of thing behind them? In
this context, I am concerned with answering these questions. This
problem is addressed using knowledge in cosmology, physics and
biology. The initial part describes the stages of the 'Genesis'
according to physical cosmology from the Big Bang to the appearance
of life on Earth. It will touch on problems of why the universe is
dominated by matter, the theory of inflation, the limits of our
knowledge on the early Universe, the lack of a theory that can
allow us to study the phases immediately after the Big Bang, the
relation between the concepts of quantum mechanics and the
existence of God. It shows how the Universe is finely regulated,
that is, the physical constants have been chosen so that life
appears in the Universe. The regulation is so strong that we are
forced to think the existence of a great designer who has created a
particular Universe like the one we are observing. This conclusion
can be avoided only if there is an infinity of universes, a
multiverse. We ask ourselves if science can create the Universe
from nothing and using the same arguments of cosmologists such as
Krauss (author of The Universe from Nothing). It is now known that
the current science does not allow the creation of a Universe from
absolutely nothing. Physics and cosmology do not deny God. Indeed,
the argument of the fine adjustment of constants is strongly
indicative of the existence of a great designer. Other evidence
confirming this comes from biology. Thousands of experiments in
recent decades highlight the impossibility of generating life in
the laboratory. There is an intrinsic order in life encoded in DNA
that is not present in experiments. Simple calculations show that
the 'blind and aimless' evolution described by neo-Darwinists such
as Dawkins does not allow the generation of life.

This book is the fruit of the first ever interdisciplinary
international scientific conference on Matthew's story of the Star
of Bethlehem and the Magi, held in 2014 at the University of
Groningen, and attended by world-leading specialists in all
relevant fields: modern astronomy, the ancient near-eastern and
Greco-Roman worlds, the history of science, and religion. The
scholarly discussions and the exchange of the interdisciplinary
views proved to be immensely fruitful and resulted in the present
book. Its twenty chapters describe the various aspects of The Star:
the history of its interpretation, ancient near-eastern astronomy
and astrology and the Magi, astrology in the Greco-Roman and the
Jewish worlds, and the early Christian world - at a generally
accessible level. An epilogue summarizes the fact-fiction balance
of the most famous star which has ever shone.
This book discusses analogies between relativistic cosmology and
various physical systems or phenomena, mostly in the earth
sciences, that are described formally by the same equations. Of the
two independent equations describing the universe as a whole, one
(the Friedmann equation) has the form of an energy conservation
equation for one-dimensional motion. The second equation is fairly
easy to satisfy (although not automatic): as a result, cosmology
lends itself to analogies with several systems. Given that a
variety of universes are mathematically possible, several analogies
exist. Analogies discussed in this book include equilibrium beach
profiles, glacial valleys, the shapes of glaciers, heating/cooling
models, freezing bodies of water, capillary fluids, Omori's law for
earthquake aftershocks, lava flows, and a few mathematical
analogies (Fibonacci's sequence, logistic equation, geodesics of
various spaces, and classic variational problems). A century of
research in cosmology can solve problems on the other side of an
analogy, which in turn can suggest ideas in gravity. Finding a
cosmic analogy solves the inverse variational problem of finding a
Lagrangian and a Hamiltonian for that system, when nobody thought
one exists. Often, the symmetries of the cosmological equations
translate in new symmetries of the analogous system. The book
surprises the reader with analogies between natural systems and
exotic systems such as possible universes.
