This brilliantly innovative textbook is intended as a first introduction to quantum mechanics and its applications. Townsend's new text shuns the historical ordering that characterizes so-called Modern Physics textbooks and applies a truly modern approach to this subject, starting instead with contemporary single-photon and single-atom interference experiments. The text progresses naturally from a thorough introduction to wave mechanics through applications of quantum mechanics to solid-state, nuclear, and particle physics, thereby including most of the topics normally presented in a Modern Physics course. Examples of topics include blackbody radiation, Bose-Einstein condensation, the band-s...

Inspired by Richard Feynman and J.J. Sakurai, A Modern Approach to Quantum Mechanics allows lecturers to expose their undergraduates to Feynman's approach to quantum mechanics while simultaneously giving them a textbook that is well-ordered, logical and pedagogically sound. This book covers all the topics that are typically presented in a standard upper-level course in quantum mechanics, but its teaching approach is new. Rather than organizing his book according to the historical development of the field and jumping into a mathematical discussion of wave mechanics, Townsend begins his book with the quantum mechanics of spin. Thus, the first five chapters of the book succeed in laying out the fundamentals of quantum mechanics with little or no wave mechanics, so the physics is not obscured by mathematics. Starting with spin systems it gives students straightfoward examples of the structure of quantum mechanics. When wave mechanics is introduced later, students should perceive it correctly as only one aspect of quantum mechanics and not the core of the subject.
Revised and updated from the original, this honest and forthwright look at families of all shapes and sizes will help you down the path of healing (whether you know you need it or whether you're just not sure). Unlocking Your Family Patterns combines decades worth of counseling wisdom and pastoral care insights into this one practical resource. Your past may hurt, and your family's patterns may have left emotional scars, but your future has not been laid in stone yet. There is hope for healing, there are lessons to learn, and there are paths toward family health. Using clinical, biblical and practical examples to help you uncover the patterns your family has lived in, this book might lead you toward the family u-turn you've been looking for.
Button-pushers come in all shapes and sizes, but they have one thing in common: Their behavior drives us crazy and makes us dream of ways to escape the mess we're in. The person who pushes your buttons is likely someone who matters to you – a spouse, a parent, a boss, a fellow church member. Almost always this difficult person is connected to you by blood, love, faith, or money, so you can't just end the relationship without causing pain and upheaval in your life. Our friends and today's culture will often advise us to abandon such relationships quickly – to end this unpleasant chapter and get on with our lives. Psychologist and author Dr. John Townsend disagrees, "Your button-pusher is ...
"The Baskerville family has been haunted for generations by a fearsome hound - a phantom beast with blazing eyes and dripping jaws. Surely it is just a legend? Then Sir Charles is found mysteriously dead in the grounds of Baskerville Hall. It is time to bring in Sherlock Holmes and Doctor Watson, to discover the truth about the family curse."--BOOK JACKET.
People Fuel outlines the twenty-two relational nutrients we all need to cultivate good relationships that provide energy, focus, and the support to be all you were meant to be. Just as good nutrition is necessary for a healthy body and physical energy, so the right kinds of relationships are critical to living a successful and confident life. If we don't take enough iron, we can develop anemia. Too little calcium leads to bone disease. In the same way, we need the twenty-two relational nutrients essential to a healthy, energized, and productive life. In People Fuel, Dr. John Townsend--psychologist, leadership consultant, and coauthor of the New York Times bestselling Boundaries--shows you ho...
Abandoned by their uncle and aunt, Kevin and Sandra run away to Gumble's Yard, a deserted row of cottages on the canal bank. But the cottages are not as empty as they thought. Strange people come and go, mysterious boxes keep arriving, and the children soon find themselves caught up in a dangerous chain of events. * This book was unique when it was first published and over the years has come to be recognized as one of the ground-breaking books of the millenium. * John Rowe Townsend is a significant author, without whom writers such as Robert Cormier and Judy Blume might not have been recognized. * This gripping story has stood the test of time in the way the children are left alone to become completely self-reliant. * John Rowe Townsend lives in Cambridge.
