Consisting of black and white pebbles and a grid-work playing board, the ancient Asian game of go appears much simpler than chess, but it continues to stump the most sophisticated supercomputers. Teach Yourself Go explains the rules of the game and, using step-by-step illustrations, helps you acquire a solid understanding of how go is played. You also learn about the origins of the game, its long history, and the body of legend, rituals, art, and literature that it has inspired.

This book is about my journey as well as the stories of several other seemingly unathletic, sedentary middle-aged people who, by discovering their own Ageless Athletes inside of them, were able to learn the power of athleticism and its ability to improve how they live their lives. It is a book not only of hope and inspiring stories but also a basic and clear guide on how to discover your own Ageless Athlete, train him or her to achieve athletic goals that you set, and change your entire self-image and way of thinking about life.

Vector calculus is the fundamental language of mathematical physics. It pro vides a way to describe physical quantities in three-dimensional space and the way in which these quantities vary. Many topics in the physical sciences can be analysed mathematically using the techniques of vector calculus. These top ics include fluid dynamics, solid mechanics and electromagnetism, all of which involve a description of vector and scalar quantities in three dimensions. This book assumes no previous knowledge of vectors. However, it is assumed that the reader has a knowledge of basic calculus, including differentiation, integration and partial differentiation. Some knowledge of linear algebra is also required, particularly the concepts of matrices and determinants. The book is designed to be self-contained, so that it is suitable for a pro gramme of individual study. Each of the eight chapters introduces a new topic, and to facilitate understanding of the material, frequent reference is made to physical applications. The physical nature of the subject is clarified with over sixty diagrams, which provide an important aid to the comprehension of the new concepts. Following the introduction of each new topic, worked examples are provided. It is essential that these are studied carefully, so that a full un derstanding is developed before moving ahead. Like much of mathematics, each section of the book is built on the foundations laid in the earlier sections and chapters.

The verses of Psalm 119, 1 Thessalonians 5:15, and Ephesians 6:1-4 set to music

What is the universe? What does that mean? I will try to explain to those persons who want to know. The universe is the large emptiness we see all around and parts we do not see yet. It is easy for us to see through it and reach out, and we touch nothing. The universe does exist because there are things that we can touch and feel. There is space around everything; this empty space. It did not exist before any parts or trees, grass, animals, people, so there was emptiness. This is called es or ethrea and exists millions and billions of years ago. There was a super intelligent being, whom we call Jehovah, and Jehovah looked all over this empty space and found no other being or no other part or thing in this emptiness that exists. He called it ethrea; he found nothing existed besides him. So he thought and thought for quite some time and decided he would create a being called animal, but there was nothing to be like him. It does not need to look like me. Nothing can be like me. It must have a place to move and a part that helps it move. It must have legs and feet to touch something to move on. So Jehovah discovered that he could speak and lots of stuff would come into existence. Now how can make this stuff form into balls, or better, Ill call it a planet or nebula. If I make it go around like a whirlwind, it will come to a center. So he caused the stuff to go round and round, and he discovered it got hot with friction. When it cooled down, it became a large ball, and he called it the sun. Some of the spinning stuff became smaller balls, and he could call those the planets and the smaller ones as moons. There were so many of these planets and moons. What could he do with them? He could make grass and trees and animals and people that could be companions. It would take many years of experiments to do this, and he had so many planets to cause to grow and many years to make the animals able to talk, and they will need to be able to eat.

This book describes the mathematical underpinnings of algorithms used for molecular dynamics simulation, including both deterministic and stochastic numerical methods. Molecular dynamics is one of the most versatile and powerful methods of modern computational science and engineering and is used widely in chemistry, physics, materials science and biology. Understanding the foundations of numerical methods means knowing how to select the best one for a given problem (from the wide range of techniques on offer) and how to create new, efficient methods to address particular challenges as they arise in complex applications. Aimed at a broad audience, this book presents the basic theory of Hamiltonian mechanics and stochastic differential equations, as well as topics including symplectic numerical methods, the handling of constraints and rigid bodies, the efficient treatment of Langevin dynamics, thermostats to control the molecular ensemble, multiple time-stepping, and the dissipative particle dynamics method.
