The science of ballistics has a long history and starts with one question: How does a projectile move through the air? Even before physicists worked that one out, military engineers had been tinkering with ballistic devices for centuries. The trebuchet of the Middle Ages has given way to rocket power, and the science of ballistics has evolved to match the technology. Mark Denny's survey covers this dynamic subject from prehistory to the weapons of tomorrow.

Taking the bang-whiz-thud approach, Denny first talks about internal ballistics--Bang --from before gunpowder to the development of modern firearms. External ballistics--Whiz --are next, with discussions about short- and long-range trajectories. Denny's lesson ends with a Thud --an explanation of terminal ballistics.

Throughout, Denny conveys applicable physics principles in a way that will appeal to technology buffs and ballistics enthusiasts alike. His fun and factual explanations are free of complicated equations; notes cover the key aspects of ballistics physics for the more technically inclined.

Denny has perfected this engaging balance of science and story. For study or hobby, "Their Arrows Will Darken the Sun" is an entertaining guide to the world of ballistics.

The book consists of two parts: A summary and critical examination of chemical theory as it developed from early beginnings through the dramatic events of the twentieth century, and a reconstruction based on a re-interpretation of the three seminal theories of periodicity, relativity and quantum mechanics in chemical context.

Anticipating the final conclusion that matter and energy are special configurations of space-time, the investigation starts with the topic of relativity, the only theory that has a direct bearing on the topology of space-time and which demonstrates the equivalence of energy and matter and a reciprocal relationship between matter and the curvature of space.

Re-examination of the first quantitative model of the atom, proposed by Bohr, reveals that this theory was abandoned before it had received the attention it deserved. It provided a natural explanation of the Balmer formula that firmly established number as a fundamental parameter in science, rationalized the interaction between radiation and matter, defined the unit of electronic magnetism and produced the fine-structure constant. These are not accidental achievements and in reworking the model it is shown, after all, to be compatible with the theory of angular momentum, on the basis of which it was first rejected with unbecoming haste.

The Sommerfeld extension of the Bohr model was based on more general quantization rules and, although more successful at the time, is demonstrated to have introduced the red herring of tetrahedrally directed elliptic orbits, which still haunts most models of chemical bonding. The gestation period between Bohr and the formulation of quantum mechanics was dominated by the discovery and recognition of wave phenomena in theories of matter, to the extent that all formulations of the quantum theory developed from the same classical-mechanical background and the Hamiltonian description of multiply-periodic systems. The reasons for the fierce debates on the interpretation of phenomena such as quantum jumps and wave models of the atom are discussed in the context of later developments. The successful, but unreasonable, suppression of the Schrodinger, Madelung and Bohm interpretations of quantum theory is shown not to have served chemistry well. The inflated claims about uniqueness of quantum systems created a mystique that continues to frighten students of chemistry. Unreasonable models of electrons, atoms and molecules have alienated chemists from their roots, paying lip service to borrowed concepts such as measurement problems, quantum uncertainty, lack of reality, quantum logic, probability density and other ghostlike phenomena without any relevance in chemistry. In fact, classical and non-classical systems are closely linked through concepts such as wave motion, quantum potential and dynamic variables.

The second part of the book re-examines the traditional concepts of chemistry against the background of physical theories adapted for chemistry. An alternative theory is formulated from the recognition that the processes of chemistry happen in crowded environments that promote activated states of matter. Compressive activation, modelled by the methods of Hartree-Fock-Slater atomic structure simulation, leads to an understanding of elemental periodicity, the electronegativity function and covalence as a manifestation of space-time structure and the golden ratio. Molecular structure and shape are related to orbital angular momentum and chemical change is shown to be dictated by the quantum potential. The empirical parameters used in computer simulations such as molecular mechanics and dynamics are shown to derive in a fundamental way from the relationship between covalence and the golden ratio, which also explains the physical basis of Pauli s exclusion principle for the first time."

Pilots must be provided explanations, predictions, factors of safety and control for high density altitude environments. Anytime a higher than standard temperature exists at a departure airport, improper planning and/or a lack of knowledge may lead to a fatal outcome. Attempting takeoff without a thorough knowledge and understanding of high density altitude takeoff parameters are known to be contributing factors in general aviation takeoff accidents. A critical ethnographic study was conducted to reveal cultural differences among the general aviation community, air carrier, and commuter and on demand operators. Takeoff distance, velocity, and time can be presented as a function of aircraft weight and provide a practical basis for other reliable information. Participants provide an unintended and unanticipated zero-rate condition encountered in an aviation operation. This study expands on participant's zero-rate concerns with ratio level measurements and graphs.

This is a book on how to design, build, and fly hydrofoil boats. It begins with the history and theory of hydrofoils, and continues with an explanation of flight characteristics, such as; stability, control, lift, drag, cavitation, and ventilation. Foil configurations, weight and balance, flying height, and roll management are covered as well as calculations of stress, hull configuration, and wing sizing. One section demonstrates methods for comparing designs, and explores specific design ideas for motorized, human powered, and sail powered hydrofoils. Piloting and trouble shooting are followed by a bibliography and index. This very complete book includes over 270 illustrations, charts and tables on the subject of creating hydrofoil boats. Because hydrofoils fly like airplanes, except in a denser fluid, the book's subject could be described as aerodynamics adapted to hydrofoils. It is the best book available for hydrofoil enthusiasts. There is no other book like it.

Geared toward advanced undergraduates and graduate students, this outstanding text surveys aeroelastic problems, their historical background, basic physical concepts, and the principles of analysis. It has also proven highly useful to designers and engineers concerned with flutter, structural dynamics, flight loads, and related subjects.

Despite the ongoing preventive actions, supervision failure remains the most serious contributor to aircraft accidents in the Brazilian Air Force (FAB). The Organizational Accidents Theory, introduced by James Reason (1997), focuses on the preexisting conditions that result from fallible decisions made by top management. Squadron Commanders are the managers who deal directly with frontline operations in the FAB, becoming the last managerial barriers to counteract flaw top-down decision-makings. The purpose of this study aims to assess squadron commanders' perceptions regarding the theory of Organizational Accidents to improve FAB's safety performance. Three research hypotheses have been formulated and answered. Surveys were sent to squadron commanders and 20 responded to them. Despite the basic understanding of aviation safety, the results show that squadron commanders need more education in advanced safety models as well as the theory of Organizational Accidents. Squadron Commanders also need a better decision-making process tailored for their managerial decisions.

The manipulation of light at the nanometer scale is highly pursued for both fundamental sciences and wide applications. The diffraction limit of light sets the limit for the smallest size of photonic devices to the scale of light wavelength. Fortunately, the peculiar properties of surface plasmons in metal nanostructures make it possible to squeeze light into nanoscale volumes and enable the manipulation of light and light-matter interactions beyond the diffraction limit. Studies on surface plasmons have led to the creation of a booming research field called plasmonics. Because of its various scientific and practical applications, plasmonics attracts researchers from different fields, making it a truly interdisciplinary subject. Nanophotonics: Manipulating Light with Plasmons starts with the general physics of surface plasmons and a brief introduction to the most prominent research topics, followed by a discussion of computational techniques for light scattering by small particles. Then, a few special topics are highlighted, including surfaceenhanced Raman scattering, optical nanoantennas, optical forces, plasmonic waveguides and circuits, and gain-assisted plasmon resonances and propagation. The book discusses the fundamental and representative properties of both localized surface plasmons and propagating surface plasmons. It explains various phenomena and mechanisms using elegant model systems with well-defined structures, is illustrated throughout with excellent figures, and contains an extensive list of references at the end of each chapter. It will help graduate-level students and researchers in nanophotonics, physics, chemistry, materials science, nanoscience and nanotechnology, and electrical and electronic engineering get a quick introduction to this field.

Plasmonic resonators, composed of metallic micro- and nanostructures, belong to the category of excited-state physics on resonances from gigahertz to petahertz. Dynamical physics is in contrast to ground-state physics, which includes thermal states, and is connected to diverse applications to enhance existing photo-induced effects and phenomena such as plasmon-enhanced photoluminescence and Raman scattering. This book has three main aims: to provide fundamental knowledge on plasmonic resonators, to explain diverse plasmonic resonators, and to stimulate further development in plasmonic resonators. Plasmon-related studies, which are sometimes called plasmonics and include a substantial portion of metamaterials, have shown significant development since the 1980s. The piled-up results are too numerous to study from the beginning, but this book summarizes those results, including the history (past), all the possible types of plasmonic resonators (present), and their wide range of applications (future). It provides the basics of plasmons and resonant physics for undergraduate students, the systematic knowledge on plasmonic resonators for graduate students, and cutting-edge and in-depth information on plasmon-enhancement studies for researchers who are not experts in plasmonics and metamaterials, thereby benefitting a wide range of readers who are interested in the nanotechnology involving metallic nanostructures.

Lukas Pehle beschaftigt sich mit der transienten thermischen und strukturmechanischen Analyse einer 19-stufigen Mitteldruck-Dampfturbine. Dafur errechnet und bewertet er Zeitdauern und auftretende Spannungen, um ein breites Spektrum an Vorwarm-Szenarien beschreiben zu koennen. Das dabei verwendete und weiterentwickelte Festkoerpermodell wird an experimentellen Daten kalibriert, um im Anschluss eine Parameterstudie durchfuhren zu koennen. Mithilfe des untersuchten Konzepts des Vorwarmens von Dampfturbinen koennen thermisch induzierte Spannungen beim Kraftwerksstart verringert werden. Dieses Buch leistet aufgrund der dadurch flexibleren Kraftwerke einen wichtigen Beitrag zur Versorgungssicherheit nach der Energiewende, also fur den UEbergang von fossilen Energietragern und der Kernenergie zu einer nachhaltigen Energieversorgung mittels erneuerbarer Energien.

Applied Computational Physics is a graduate-level text stressing three essential elements: advanced programming techniques, numerical analysis, and physics. The goal of the text is to provide students with essential computational skills that they will need in their careers, and to increase the confidence with which they write computer programs designed for their problem domain. The physics problems give them an opportunity to reinforce their programming skills, while the acquired programming skills augment their ability to solve physics problems. The C++ language is used throughout the text. Physics problems include Hamiltonian systems, chaotic systems, percolation, critical phenomena, few-body and multi-body quantum systems, quantum field theory, simulation of radiation transport, and data modeling. The book, the fruit of a collaboration between a theoretical physicist and an experimental physicist, covers a broad range of topics from both viewpoints. Examples, program libraries, and additional documentation can be found at the companion website. Hundreds of original problems reinforce programming skills and increase the ability to solve real-life physics problems at and beyond the graduate level.

The role of thermodynamics in modern physics is not just to provide an approximate treatment of large thermal systems, but, more importantly, to provide an organising set of ideas. Thermodynamics: A complete undergraduate course presents thermodynamics as a self-contained and elegant set of ideas and methods. It unfolds thermodynamics for undergraduate students of physics, chemistry or engineering, beginning at first year level. The book introduces the necessary mathematical methods, assuming almost no prior knowledge, and explains concepts such as entropy and free energy at length, with many examples. This book aims to convey the style and power of thermodynamic reasoning, along with applications such as Joule-Kelvin expansion, the gas turbine, magnetic cooling, solids at high pressure, chemical equilibrium, radiative heat exchange and global warming, to name a few. It mentions but does not pursue statistical mechanics, in order to keep the logic clear.
