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 These results will eventually be superseded by new data, better analysis techniques, and more complex models.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 will benefit a reader with a background in physical sciences and applied mathematics interested in the mathematical models of genetic evolution. In the first chapter, we analyze several thought experiments based on a basic model of stochastic evolution of a single genomic site in the presence of the factors of random mutation, directional natural selection, and random genetic drift. In the second chapter, we present a more advanced theory for a large number of linked loci. In the third chapter, we include the effect of genetic recombination into account and find out the advantage of sexual reproduction for adaptation. These models are useful for the evolution of a broad range of asexual and sexual populations, including virus evolution in a host and a host population.

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.

Active geophysical monitoring is an important new method for studying time-evolving structures and states in the tectonically active Earth's lithosphere. It is based on repeated time-lapse observations and interpretation of rock-induced changes in geophysical fields periodically excited by controlled sources. In this book, the results of strategic systematic development and the application of new technologies for active geophysical monitoring are presented. The authors demonstrate that active monitoring may drastically change solid Earth geophysics, through the acquisition of substantially new information, based on high accuracy and real-time observations. Active monitoring also provides new means for disaster mitigation, in conjunction with substantial international and interdisciplinary cooperation.

In this book we will look at what planetary nebulae are, where they come from and where they go. We will discuss what mechanisms cause these beautiful markers of stellar demise as well as what causes them to form their variety of shapes. How we measure various aspects of planetary nebulae such as what they are made of will also be explored. Though we will give some aspects of planetary nebulae mathematical treatment, the main points should be accessible to people with only a limited background in mathematics. A short glossary of some of the more arcane astronomical terms is at the end of the book to help in understanding. Included at the end of each chapter is an extensive bibliography to the peer reviewed research on these objects and I would encourage the reader interested in an even deeper understanding to read these articles.

The Lunar Reconnaissance Orbiter (LRO) was successfully launched on June 18, 2009 and joined an international eet of satellites (Japan's SELENE/Kaguya, China's Chang'E, and India's Chandrayaan-1) that have recently orbited the Moon for scienti c exploration p- poses. LRO is the rst step to ful ll the US national space goal to return humans to the Moon's surface, which is a primary objective of NASA's Exploration Systems Mission - rectorate (ESMD). TheinitialLROmissionphasehasaone-yeardurationfullyfundedunder ESMD support. LRO is expected to have an extended phase of operations for at least two additional years to undertake further lunar science measurements that are directly linked to objectives outlined in the National Academy of Science's report on the Scienti c Context for Exploration of the Moon (SCEM). All data from LRO will be deposited in the Planetary Data System (PDS) archive so as to be usable for both exploration and science by the widest possible community. A NASA Announcement of Opportunity (AO) solicited proposals for LRO instruments with associated exploration measurement investigations. A rigorous evaluation process - volving scienti c peer review, in combination with technical, cost and management risk assessments, recommended six instruments for LRO development and deployment. The competitively selected instruments are: Cosmic Ray Telescope for the Effects of Rad- tion (CRaTER), Diviner Lunar Radiometer Experiment (DLRE), Lyman-Alpha Mapping Project (LAMP), Lunar Exploration Neutron Detector (LEND), Lunar Orbiter Laser - timeter (LOLA), and Lunar Reconnaissance Orbiter Camera (LROC).

This book is intended to be a course about the creation and evolution of the universe at large, including the basic macroscopic building blocks (galaxies) and the overall large-scale structure. This text covers a broad range of topics for a graduate-level class in a physics department where students' available credit hours for astrophysics classes are limited. The sections cover galactic structure, external galaxies, galaxy clustering, active galaxies, general relativity and cosmology.

This book is the Second Edition of the ground-breaking book on faster-than-light travel Bright Stars, Bright Universe: Advancing Civilization by Colonization of the Solar System and the Stars using a Fast Quark Drive which described a new approach to spacecraft propulsion that could enable Mankind to travel to the stars, and beyond, to the galaxies of the known universe. In this edition we add Appendices to the original edition (together with a few minor changes to the First Edition) on Seeing and Navigating through the Cosmos on superluminal starships; Complex Thrust using Braided Accelerators; Suspended Animation to keep the biological clocks of starship occupants in sync with earth time; Engineering very long life starship and life support components; Robot guidance and robot exploratory starships; and Fuel consumption on starships. At the time of this writing the United States appears headed towards a deficit of ten or eleven trillion dollars over the next ten years. It appears that a likely cost for starship R&D would be of the order of half a trillion dollars spread over perhaps thirty years - a small amount relative to the projected US deficit - with an enormous reward for success. On a yearly basis this expense averages to about seventeen billion dollars per year. Since the NASA budget is eighteen billion dollars a year, the cost of the starship program is comparable and quite affordable. The formation of an international consortium would further reduce the per country costs. If the United States paid sixty per cent of the costs then its share would be about ten billion dollars per year. It is a venture of great significance to the future of Mankind. The cost is relatively small; the benefits are potentially enormous! In a series of recent books we explored the theoretical importance of superluminal (faster-than-light) particles called tachyons in the derivation of the form of the Standard Model of Elementary Particles. We also showed some of the remarkable features of superluminal particles such as reverse fission, length dilation, and time contraction - quite the opposite of sublight phenomena. In this book we examine the possibility of superluminal starship propulsion for interstellar exploration and colonization. We begin the book with a statement of the earth's present condition and the need to expand into space or face a slow decline into a cultural and social miasma. Then we develop a new plan for the exploration and colonization of this solar system since it appears that current announced plans have missed the mark and do not have an overall long-term approach. Since this solar system lacks enough planets that are congenial for human life we consider the possibility of colonizing planets around other stars. Many plans have been proposed for interstellar spaceships - starships. But they are usually impractical for some good reason(s). In this book we will consider superluminal (beyond light speed) starships based on tachyon dynamics. They provide a practical means of starship propulsion although much R&D must be done before the proposed starships can be built. Once built they will support speeds up to 5,000 to 30,000 times the speed of light and beyond making the universe Mankind's backyard. Travel times to other galaxies could be as short as a few months. Superluminal starships open the door to a vast expansion of humanity into the universe in the large! As world population grows, and human social needs also grow, the capacity of the world to mount a major space effort will diminish. So a major space initiative with a well-thought out game plan is required now, while we still have the resources.
