The book also discusses future directions and perspectives in the various fields of nuclear astrophysics research. In addition, it also includes a limited number of section of more general interest on double beta decay and dark matter.
Key features: Complete introductory overview of cosmic ray physics Covers the origins, acceleration, transport mechanisms and detection of these particles Mathematical and technical detail is kept separate from the main text
The review papers in this volume provide an in-depth examination of complex astrophysical phenomena of star formation via multi-wavelength observations and modeling. Among the fundamental issues discussed in the book are: The role of gravity and magnetized turbulence in the formation and evolution of molecular clouds The stellar feedback (supernovae, HII regions, winds, cosmic rays) in regulating star formation The origin of the stellar initial mass function and its universality across various environments Jets, magnetic fields and high energy particles in stellar clusters The origin of the first stars and black holes The goal of these papers is to review the major processes governing star formation and to investigate how they are interlinked. In doing so, they provide an in-depth look at the tremendous theoretical and observational progress that has been made in the recent past and also outline future perspectives. Previously published in Space Science Reviews in the Topical Collection "Star Formation"
Here is an accurate and readable translation of a seminal article by Henri Poincare that is a classic in the study of dynamical systems popularly called chaos theory. In an effort to understand the stability of orbits in the solar system, Poincare applied a Hamiltonian formulation to the equations of planetary motion and studied these differential equations in the limited case of three bodies to arrive at properties of the equations' solutions, such as orbital resonances and horseshoe orbits. Poincare wrote for professional mathematicians and astronomers interested in celestial mechanics and differential equations. Contemporary historians of math or science and researchers in dynamical systems and planetary motion with an interest in the origin or history of their field will find his work fascinating.
This book is a collection of lectures given in August 2006 at the
Les Houches Summer School on Particle Physics and Cosmology: the
Fabric of Spacetime . It provides a pedagogical introduction to the
various aspects of both particle physics beyond the Standard Model
and Cosmology of the Early Universe, covering each topic from the
basics to the most recent developments.
R.N. Wilson's two-volume treatise on reflecting telescope optics has become a classic in its own right. It is intended to give a complete treatment of the subject, addressing the professional in research and industry as well as students of astronomy and amateur astronomers. This first volume, Basic Design Theory and its Historical Development, is devoted to the theory of reflecting telescope optics and systematically recounts the historical progress. The author's approach is morphological, with strong emphasis on the historical development. The book is richly illustrated including spot-diagrams analysing special systems in modern form. In this second edition, the historical section has been revised. Various improvements to the text have been made and new systems such as the 4-lens corrector of Delabre and the LADS corrector are now covered in this volume. The concluding part II treats Manufacture, Testing, Alignment, Modern Techniques.
Discusses recent advances and new problems in the exploration of the Sun's interior structure, solar dynamics and dynamo, mechanisms of sunspot and active regions formation, sources of solar irradiance variations and links between the subsurface dynamics, flaring and CME activity. NASA's Solar Dynamics Observatory (SDO) mission has provided a large amount of new data on solar dynamics and magnetic activities during the rising phase of the current and highly unusual solar cycle. These data are complemented by the continuing SOHO mission and by ground-based observatories that include the GONG helioseismology network and the New Solar Telescope. Also, the observations are supported by realistic numerical simulations on supercomputers. This unprecedented amount of data provides a unique opportunity for multi-instrument investigations that address fundamental problems of the origin of solar magnetic activity at various spatial and temporal scales. This book demonstrates that the synergy of high-resolution multi-wavelength observations and simulations is a key to uncovering the long-standing puzzles of solar magnetism and dynamics. This volume is aimed at researchers and graduate students active in solar physics and space science. Originally published in Solar Physics journal, Vol. 287/1-2, 2013.
What if life isn't just a part of the universe . . . what if it determines the very structure of the universe itself? The theory that blew your mind in Biocentrism and Beyond Biocentrism is back, with brand-new research revealing the startling truth about our existence. What is consciousness? Why are we here? Where did it all come from-the laws of nature, the stars, the universe? Humans have been asking these questions forever, but science hasn't succeeded in providing many answers-until now. In The Grand Biocentric Design, Robert Lanza, one of Time Magazine's "100 Most Influential People," is joined by theoretical physicist Matej Pavsic and astronomer Bob Berman to shed light on the big picture that has long eluded philosophers and scientists alike. This engaging, mind-stretching exposition of how the history of physics has led us to Biocentrism-the idea that life creates reality-takes readers on a step-by-step adventure into the great science breakthroughs of the past centuries, from Newton to the weirdness of quantum theory, culminating in recent revelations that will challenge everything you think you know about our role in the universe. This book offers the most complete explanation of the science behind Biocentrism to date, delving into the origins of the memorable principles introduced in previous books in this series, as well as introducing new principles that complete the theory. The authors dive deep into topics including consciousness, time, and the evidence that our observations-or even knowledge in our minds-can affect how physical objects behave. The Grand Biocentric Design is a one-of-a-kind, groundbreaking explanation of how the universe works, and an exploration of the science behind the astounding fact that time, space, and reality itself, all ultimately depend upon us.
The Golden Oldies series of the journal General Relativity and Gravitation reprints important papers in general relativity theory that were published 30 or more years ago and are either hard to get hold of, or were originally printed in a language other than English. They play a key part in making these important papers readily accessible today, in the language that has now become the lingua franca of scientific publication. The value of this reprinting is enhanced by an accompanying editorial note for each paper, which briefly explains the significance of the work and where it has subsequently led to, together with a biographical note about the author or authors. This volume presents a selection of 14 rarities among the Golden Oldies grouped in the three categories "Basic results in differential geometry and general relativity," "Discussion of physical effects" and "Basic exact solutions and their interpretation." Researchers in the field will appreciate having these important papers collected in one book for the first time. Reprinted from the journal General Relativity and Gravitation.
The nature of dark matter remains one of the preeminent mysteries in physics and cosmology. It appears to require the existence of new particles whose interactions with ordinary matter are extraordinarily feeble. One well-motivated candidate is the axion, an extraordinarily light neutral particle that may possibly be detected by looking for their conversion to detectable microwaves in the presence of a strong magnetic field. This has led to a number of experimental searches that are beginning to probe plausible axion model space and may reveal the axion in the near future. These proceedings discuss the challenges of designing and operating tunable resonant cavities and detectors at ultralow temperatures. The topics discussed here have potential application far beyond the field of dark matter detection and may be applied to resonant cavities for accelerators as well as designing superconducting detectors for quantum information and computing applications. This work is intended for graduate students and researchers interested in learning the unique requirements for designing and operating microwave cavities and detectors for direct axion searches and to introduce several proposed experimental concepts that are still in the prototype stage.
Originally published in 1995, Creation and Evolution in the Early American Scientific Affiliation is the tenth volume in the series, Creationism in Twentieth Century America, reissued in 2021. The volume comprises of original primary sources from the American Science Affiliation, a group formed following an invitation from the president of the Moody Bible Institute in Chicago, in answer to the perceived need for an academic society for American Evangelical Scientists to explicate the relationship between science and faith. The society confronted the debate between creation and evolution head on, leaving a paper trail documenting their thoughts and struggles. This diverse and expansive collection includes 53 selections that appeared during the organisation’s first two decades and focuses on the encounter between science and American evangelicalism in the twentieth century, in particular the debates surrounding the ever-increasing preference for evolutionary theory. The collection will be of especial interest to natural historians, and theologians as well as academics of philosophy, and history.

The Optical Society of America Conference on Applications of High Fields and Short Wavelength Sources, held in Santa Fe, New Mexico, USA, from March 20-22, 1997, was an exceptionally exciting conference. This conference was the seventh in a series of topical con ferences, held every two years, which are devoted to the generation and application of high field and short wavelength sources. The meeting was truly international in scope, with equal participation from both within and outside of the US. In the past two years, there has been dramatic progress in both laser and x-ray coher ent sources, both fundamental and applied. The 1997 meeting highlighted these advances, which are summarized in sections 1 and 2 of this volume. Terawatt-class lasers are now avail able in the UV or at high repetition rates. Michael Perry (LLNL) presented a keynote talk on petawatt class lasers and their applications in inertial confinement fusion, while Jorge Rocca (Colorado State University) presented a keynote talk on tabletop soft-x-ray lasers. Genera tion and measurement techniques are becoming very sophisticated throughout the UV and x ray region of the spectrum, and coherent sources have been extended to wavelengths below 30A. Phase control in the x-ray region is also now possible, and new phase-matching schemes in the UV have been experimentally demonstrated. It is clear that a new field of x-ray nonlin ear optics will deveiop rapidly over the next few years."
Written for amateur physicists, "SlipString Drive" takes you through the basics of string and M-theories so that you can embark on a "faster than light" voyage without violating physics. By using gravity waves to completely isolate volumes of spacetime from the rest of the universe, author Andrew L. Bender proposes a method of travel-similar to going through a wormhole-that could be possible within fifty years. He also details a unique engine design for producing the gravity waves necessary to travel in such a manner. In "SlipString Drive," Bender describes how ships using this method of propulsion would appear to those outside of the ship's partially "gravitationally isolated" region of space while maneuvering at slow speeds. Bender also discusses novel uses for such a vessel, such as saving humanity from comets to supernovae. Bender also offers a "Membrane Theory of Gravity." A modification of M-theory, this new theory unifies all forces, and predicts dark matter and energy. It also theorizes how the acceleration of our universe will change over time, along with other predictions that could prove modified M-theory correct observationally-a feat no other cosmologist has yet achieved. Finally, Bender hypothesizes how the universe will end, and how our descendants could survive that fateful occurrence.
This book focuses on the characteristics of optical radiation, or a spectrum, emitted by various plasmas. In plasma, the same atomic species can produce quite different spectra, or colors depending on the nature of the plasma. This book gives a theoretical framework, by which a particular spectrum can be interpreted correctly and coherently. The uniqueness of the book lies in its comprehensive treatment of the intensity distribution of spectral lines and the population density distribution among the atomic levels, in plasma. It is intended to provide beginners with a good perspective of the field, laying out the physics in an extremely clear manner, starting from an elementary level. A very useful feature of the book is the asterisked sections and chapters which can be skipped by readers, who only wish to gain a quick and basic introduction to plasma spectroscopy. It will also be very useful to researchers working actively in the field, acting as a guide for carrying out experiments and interpreting experimental observations.

As in the days following Skylab, solar physics came to the end of an era when the So lar Maximum Mission re-entered the earth's atmosphere in December 1989. The 1980s had been a pioneering decade not only in space- and ground-based studies of the solar atmosphere (Solar Maximum Mission, Hinotori, VLA, Big Bear, Nanc;ay, etc.) but also in solar-terrestrial relations (ISEE, AMPTE), and solar interior neutrino and helioseismol ogy studies. The pace of development in related areas of theory (nuclear, atomic, MHD, beam-plasma) has been equally impressive. All of these raised tantalizing further questions about the structure and dynamics of the Sun as the prototypical and best observed star. This Advanced Study Institute was timed at a pivotal point between that decade and the realisation of Yohkoh, Ulysses, SOHO, GRANAT, Coronas, and new ground-based optical facilities such as LEST and GONG, so as to teach and inspire the up and coming young solar researchers of the 1990s. The topics, lecturers, and students were all chosen with this goal in mind, and the result seems to have been highly successful by all reports."

The Sun as a Guide to Stellar Physics illustrates the significance of the Sun in understanding stars through an examination of the discoveries and insights gained from solar physics research. Ranging from theories to modeling and from numerical simulations to instrumentation and data processing, the book provides an overview of what we currently understand and how the Sun can be a model for gaining further knowledge about stellar physics. Providing both updates on recent developments in solar physics and applications to stellar physics, this book strengthens the solar-stellar connection and summarizes what we know about the Sun for the stellar, space, and geophysics communities.
Based on 3D smoothed particle hydrodynamics simulations performed with unprecedented high resolution, this book examines the giant impacts that dominate many planets' late accretion and evolution. The numerical methods developed are now publicly available, greatly facilitating future studies of planetary impacts in our solar system and exoplanetary systems. The book focuses on four main topics: (1) The development of new methods to construct initial conditions as well as a hydrodynamical simulation code to evolve them, using 1000 times more simulation particles than the previous standard. (2) The numerical convergence of giant impact simulations -- standard-resolution simulations fail to converge on even bulk properties like the post-impact rotation period. (3) The collision thought to have knocked over the planet Uranus causing it to spin on its side. (4) The erosion of atmospheres by giant impacts onto terrestrial planets, and the first full 3D simulations of collisions in this regime.
Dust and molecules are found in a large variety of astrophysical environments, in particular in the circumstellar material ejected by evolved stars. This book brings together the leading astronomers and astrophysicists in the field of molecular astrophysics and stellar physics to discuss the important issues of dust and molecular formation, the role of solids in circumstellar environments, molecules as probes of circumstellar parameters, the stellar contribution to the enrichment of the Galaxy, and the latest observational data in various wavelength domains, in partiular in the infrared with results from the Infrared Space Observatory. The astrophysical senarios include late-type stars, novae, Wolf-Rayet stars, Luminous Blue Variables and supernovae. Audience: Researchers and graduate students in the fields of stellar physics, stellar evolution and astrochemistry.
The question of the existence of other worlds and other living beings has been present in the human quest for knowledge since as far as Epicurus. For centuries this question belonged to the fields of philosophy and theology. The theoretical problem of the formation of the Solar System, and hence of other planetary systems, was tackled only during the 18th century, while the first observational attempts for a detection started less than one hundred years ago. Direct observation of an extra-solar planetary system is an extraordinarily difficult problem: extra-solar planets are at huge distances, are incredibly faint and are overwhelmed by the bright light of their own stars. With virtually no observational insight to test their models, theoreticians have remained for decades in a difficult position to make substantial progress. Yet, the field of stellar formation has provided since the 1980s both the the oretical and observational evidences for the formation of discs at the stage of star birth and for debris materials orbiting the very young stellar systems. It was tempting to consider that these left-overs might indeed later agglomerate into planetary systems more or less similar to ours. Then came observational evidences for planets outside the Solar System."
Stellar magnetism is the study of the magnetic field of the Sun and other stars and is a rapidly developing field of astrophysics. This book, an authoritative account with broad astronomical scope, has grown out of the lifelong work of an outstanding researcher in the subject.
Our concepts of the sun have been altered by four new developments--the discovery of apparent global solar oscillations, an unsettled and unsettling deficit of neutrinos from the center of the sun, a new elucidation of the role of solar wind, and some disturbing historical facts that shake old concepts of solar constancy and regularity. This volume brings together summaries of these four developments in solar physics, written by the four scientists whose work has prompted our new assessment of the sun.
