This book discusses in detail all the relevant numerical methods for the classical N-body problem. It demonstrates how to develop clear and elegant algorithms for models of gravitational systems, and explains the fundamental mathematical tools needed to describe the dynamics of a large number of mutually attractive particles. Particular attention is given to the techniques needed to model astrophysical phenomena such as close encounters and the dynamics of black hole binaries. The author reviews relevant work in the field and covers applications to the problems of planetary formation and star cluster dynamics, both of Pleiades type and globular clusters. Self-contained and pedagogical, this book is suitable for graduate students and researchers in theoretical physics, astronomy and cosmology.

A powerful new approach to natural, intuitive whole-body healing. The Body Code is a truly revolutionary method of holistic healing. Dr. Bradley Nelson, a globally renowned expert in bioenergetic medicine, has spent decades teaching his powerful self-healing method and training practitioners around the globe, but this is the first time his system of healing will be available to the general public in the form of The Body Code. The Body Code is based on the simple premise that the body is self-healing and knows what it needs in order to thrive and flourish. The Body Code method allows readers to tap into this inner knowing, and find imbalances in 6 key areas—Energies, Circuits and Systems, Toxicity, Nutrition and Lifestyle, Misalignments, and Pathogens—that are the root causes of our physical, mental and emotional issues. By identifying and releasing these imbalances, readers become empowered to activate their body's innate healing power. Featuring a foreword from George Noory, host of Coast to Coast AM, and filled with powerful first-hand accounts of healing, hundreds of color illustrations, and concrete, actionable steps, The Body Code is a road map to healing based in deep study of the human body, time-proven ancient practices, and the unlimited power of the subconscious mind.

In this classic text, a Nobel Prize-winning astrophysicist presents the theory of stellar dynamics as a branch of classical dynamics--a discipline in the same general category as celestial mechanics. His method offers the advantages of clarifying the theory's fundamental issues and defining its underlying motivations. S. Chandrasekhar investigates two areas. The first concerns problems in which the time of relaxation of a stellar system is central. His method consists of analyzing the effects of stellar encounters in terms of the two-body problem of classical dynamics and applying this theory to the dynamics of star clusters. The second area investigates problems centering around Liouville's theorem and the solutions of the equation of continuity; here, the author discusses the dynamic implications of the existence of a field of differential motions, which appears to be the most striking kinematic feature of the galaxy and the extragalactic systems. This edition includes two papers by the author that were published after Principles of Stellar Dynamics and that have been studied and quoted extensively: "New Methods in Stellar Dynamics" (originally published in the Annals of the New York Academy of Sciences) and "Dynamical Friction" (originally published in The Astrophysical Journal).

"I believe that the discoveries in this book can change our understanding of how we store emotional experiences and in so doing, change our lives. The Emotion Code has already changed many lives around the world, and it is my hope that millions more will be led to use this simple tool to heal themselves and their loved ones."—Tony Robbins In this newly revised and expanded edition of The Emotion Code, renowned holistic physician and lecturer Dr. Bradley Nelson skillfully lays bare the inner workings of the subconscious mind. He reveals how emotionally-charged events from your past can still be haunting you in the form of "trapped emotions"—emotional energies that literally inhabit your body. These trapped emotions can fester in your life and body, creating pain, malfunction, and eventual disease. They can also extract a heavy mental and emotional toll on you, impacting how you think, the choices that you make, and the level of success and abundance you are able to achieve. Perhaps most damaging of all, trapped emotional energies can gather around your heart, cutting off your ability to give and receive love. The Emotion Code is a powerful and simple way to rid yourself of this unseen baggage. Dr. Nelson’s method gives you the tools to identify and release the trapped emotions in your life, eliminating your “emotional baggage,” and opening your heart and body to the positive energies of the world. Filled with real-world examples from many years of clinical practice, The Emotion Code is a distinct and authoritative work that has become a classic on self-healing.

An introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. This book offers both an introduction to the laws of celestial mechanics and a step-by-step guide to developing software for direct use in astrophysics research. It bridges the gap between conventional textbooks, which present a rigorous and exhaustive exposition of theoretical concepts, and applying the theory to tackle real experiments. The text is written engagingly in dialogue form, presenting the research journey of the fictional Alice, Bob, and Professor Starmover. Moving Planets Around not only educates students on the laws of Newtonian gravity, it also provides all that they need to start writing their own software, from scratch, for simulating the dynamical evolution of planets and exoplanets, stars, or other heavenly bodies.

Computer simulation of systems has become an important tool in scientific research and engineering design, including the simulation of systems through the motion of their constituent particles. Important examples of this are the motion of stars in galaxies, ions in hot gas plasmas, electrons in semiconductor devices, and atoms in solids and liquids. The behavior of the system is studied by programming into the computer a model of the system and then performing experiments with this model. New scientific insight is obtained by observing such computer experiments, often for controlled conditions that are not accessible in the laboratory. Computer Simulation using Particles deals with the simulation of systems by following the motion of their constituent particles. This book provides an introduction to simulation using particles based on the NGP, CIC, and P3M algorithms and the programming principles that assist with the preparations of large simulation programs based on the OLYMPUS methodology. It also includes case study examples in the fields of astrophysics, plasmas, semiconductors, and ionic solids as well as more detailed mathematical treatment of the models, such as their errors, dispersion, and optimization. This resource will help you understand how engineering design can be assisted by the ability to predict performance using the computer model before embarking on costly and time-consuming manufacture.

Published under the auspices of the Royal Astronomical Society, this volume contains a set of extensive school tested lectures, with the aim to give a coherent and thorough background knowledge of the subject and to introduce the latest developments in N-body computational astrophysics. The topics cover a wide range from the classical few-body problem with discussions of resonance, chaos and stability to realistic modelling of star clusters as well as descriptions of codes, algorithms and special hardware for N-body simulations. This collection of topics, related to the gravitational N-body problem, will prove useful to both students and researchers in years to come. 1) Published under the auspices of the Royal Astronomical Society.
