The growing number of scientific and technological applications of
plasma physics in the field of Aerospace Engineering requires that
graduate students and professionals understand their principles.
This introductory book is the expanded version of class notes of
lectures I taught for several years to students of Aerospace
Engineering and Physics. It is intended as a reading guide,
addressed to students and non-specialists to tackle later with more
advanced texts. To make the subject more accessible the book does
not follow the usual organization of standard textbooks in this
field and is divided in two parts. The first introduces the basic
kinetic theory (molecular collisions, mean free path, etc.) of
neutral gases in equilibrium in connection to the undergraduate
physics courses. The basic properties of ionized gases and plasmas
(Debye length, plasma frequencies, etc.) are addressed in relation
to their equilibrium states and the collisional processes at the
microscopic level. The physical description of short and long-range
(Coulomb) collisions and the more relevant collisions (elementary
processes) between electrons' ions and neutral atoms or molecules
are discussed. The second part introduces the physical description
of plasmas as a statistical system of interacting particles
introducing advanced concepts of kinetic theory, (non-equilibrium
distribution functions, Boltzmann collision operator, etc). The
fluid transport equations for plasmas of electron ions and neutral
atoms and the hydrodynamic models of interest in space science and
plasma technology are derived. The plasma production in the
laboratory in the context of the physics of electric breakdown is
also discussed. Finally, among the myriad of aerospace applications
of plasma physics, the low pressure microwave electron multipactor
breakdown and plasma thrusters for space propulsion are presented
in two separate chapters.
Galileo's groundbreaking dialogues are a summation of three decades
of scientific work he had undertaken in the fledgling field of
physics. This edition includes the diagrams crucial for
understanding the text. Writing these dialogues in 1638, the
elderly Galileo had a life of achievements behind him. Despite
attempts at suppression of his writings by the Roman Inquisition,
his ideas were successfully communicated across Europe. The motion
of objects and resistance to such motion, the concept of velocity,
and the laws of gravity are merely a few of the topics covered in
these detailed dialogues. At the outset, we are introduced to the
three conversation partners: Salviati, Sagredo and Simplicio. These
three Venetians embark on a scientific discussion, hoping to
explain the curiosities of things such as speed and movement. Over
the course of four days, their meetings grow in complexity and
scope as they strive to explain physical phenomena.
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.
The development of man's understanding of planetary motions is the
crown jewel of Newtonian mechanics. This book offers a concise but
self-contained handbook-length treatment of this historically
important topic for students at about the third-year-level of an
undergraduate physics curriculum. After opening with a review of
Kepler's three laws of planetary motion, it proceeds to analyze the
general dynamics of 'central force' orbits in spherical
coordinates, how elliptical orbits satisfy Newton's gravitational
law, and how the geometry of ellipses relates to physical
quantities, such as energy and momentum. Exercises are provided,
and derivations are set up in such a way that readers can gain
analytic practice by filling in the missing steps. A brief
bibliography lists sources for readers who wish to pursue further
study on their own.
Many physical properties of our universe, such as the relative
strength of the fundamental interactions, the value of the
cosmological constant, etc., appear to be fine-tuned for existence
of human life. One possible explanation of this fine tuning assumes
existence of a multiverse, which consists of a very large number of
individual universes having different physical properties.
Intelligent observers populate only a small subset of these
universes, which are fine-tuned for life. In this book we will
review several interesting metamaterial systems, which capture many
features of important cosmological models and offer insights into
the physics of many other non-trivial spacetime geometries, such as
microscopic black holes, closed time-like curves (CTCs) and the
Alcubierre warp drive.
Cosmology is the study of the origin, size, and evolution of the
entire universe. Every culture has developed a cosmology, whether
it be based on religious, philosophical, or scientific principles.
In this book, the evolution of the scientific understanding of the
Universe in Western tradition is traced from the early Greek
philosophers to the most modern 21st century view. After a brief
introduction to the concept of the scientific method, the first
part of the book describes the way in which detailed observations
of the Universe, first with the naked eye and later with
increasingly complex modern instruments, ultimately led to the
development of the "Big Bang" theory. The second part of the book
traces the evolution of the Big Bang including the very recent
observation that the expansion of the Universe is itself
accelerating with time.
This book is based on a set of 18 class-tested lectures delivered
to fourth-year physics undergraduates at Grifi th University in
Brisbane, and the book presents new discoveries by the Nobel-prize
winning LIGO collaboration. The author begins with a review of
special relativity and tensors and then develops the basic elements
of general relativity (a beautiful theory that unifies special
relativity and gravitation via geometry) with applications to the
gravitational deflection of light, global positioning systems,
black holes, gravitational waves, and cosmology. The book provides
readers with a solid understanding of the underlying physical
concepts; an ability to appreciate and in many cases derive
important applications of the theory; and a solid grounding for
those wishing to pursue their studies further. General Relativity:
An Introduction to Black Holes, Gravitational Waves, and Cosmology
also connects general relativity with broader topics. There is no
doubt that general relativity is an active and exciting field of
physics, and this book successfully transmits that excitement to
readers.
All matter, including galaxy clusters, galaxies, and their
constituents follow orbits and flows driven by the net attraction
of near and distant masses. The book presents the development of
studies of peculiar motions along with discoveries in large-scale
structure, the cosmic microwave background, baryonic oscillations,
gravity waves, and their relation to current work on gravitation
and dark matter.The results of peculiar motion measurements in the
late 20th century are described as they were used to search for the
dipole of the galaxy motions, a determination of cosmic density,
and to compare with the cosmic microwave dipole, which led to the
discovery of galactic flows and the Great Attractor. Newer detailed
measurements from surveys in the 21st century have helped resolve
the nature of these structures. Some prospects for future
investigations are discussed.
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.
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.
This is an in-depth look at baryon number violation in the Standard
Model including the necessary background in finite temperature
field theory, plasma dynamics and how to calculate the out of
equilibrium evolution of particle number densities throughout a
phase transition. It is a self-contained pedagogical review of the
theoretical background to electroweak baryogenesis as well as a
summary of the other prevailing mechanisms for producing the
asymmetry between matter and antimatter using the Minimal
Supersymmetric Standard Model as a pedagogical tool whenever
appropriate.
This book presents a brief compilation of results from nearly a
century of research on the globular star clusters in the Andromeda
Galaxy (M31). It explores the techniques and limitations of the
observations, the successes and challenges of the models, and the
paradigm for the formation of M31 that has gradually emerged. These
results will eventually be superseded by new data, better analysis
techniques, and more complex models. However, the emphasis of this
book is on the techniques, thought processes, and connections with
other studies.
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.
The book is an introduction to the subject of fluid mechanics,
essential for students and researchers in many branches of science.
It illustrates its fundamental principles with a variety of
examples drawn mainly from astrophysics and geophysics as well as
from everyday experience. Prior familiarity with basic
thermodynamics and vector calculus is assumed.
