Topological solitons occur in many nonlinear classical field theories. They are stable, particle-like objects, with finite mass and a smooth structure. Examples are monopoles and Skyrmions, Ginzburg-Landau vortices and sigma-model lumps, and Yang-Mills instantons. This book is a comprehensive survey of static topological solitons and their dynamical interactions. Particular emphasis is placed on the solitons which satisfy first-order Bogomolny equations. For these, the soliton dynamics can be investigated by finding the geodesics on the moduli space of static multi-soliton solutions. Remarkable scattering processes can be understood this way. The book starts with an introduction to classical field theory, and a survey of several mathematical techniques useful for understanding many types of topological soliton. Subsequent chapters explore key examples of solitons in one, two, three and four dimensions. The final chapter discusses the unstable sphaleron solutions which exist in several field theories.

What you have here is a book about Christian Ethics, which may sound daunting, but it''s not. Christian Ethics is just the technical name for how we live a Christian life. In this case, we’ll be working your way through the Lord''s Prayer. Not many people think about the Lord''s Prayer as a guide— it''s a prayer.Several years ago, as I went through my daily prayers, I had a Blazing Glimpse of the Obvious: Jesus said, "Pray then like this," and gave us the Lord''s Prayer. Ok, says I to myself, if that''s how Jesus wants me to pray, then I guess I had best pray that way. I also began to meditate on what each of the parts of the prayer meant.This book is not technical. Oh, sure, there are a couple of Greek words here and there, but that''s just so you get an idea that no matter how it''s translated into English, we miss something. Don''t worry about it; you don''t need to know Greek. There are also a couple of interesting historical bits. I find them fascinating, but you will have to judge for yourself.
