Dr Field and Brush Mower

An accessible, comprehensive reference to modern quantum mechanics and field theory. In surveying available books on advanced quantum mechanics and field theory, Franz Gross determined that while established books were outdated, newer titles tended to focus on recent developments and disregard the basics. "Relativistic Quantum Mechanics and Field Theory" fills this striking gap in the field. With a strong emphasis on applications to practical problems as well as calculations, Dr. Gross provides complete, up-to-date coverage of both elementary and advanced topics essential for a well-rounded understanding of the field. Developing the material at a level accessible even to newcomers to quantum mechanics, the book begins with topics that every physicist should know quantization of the electromagnetic field, relativistic one body wave equations, and the theoretical explanation of atomic decay. Subsequent chapters prepare readers for advanced work, covering such major topics as gauge theories, path integral techniques, spontaneous symmetry breaking, and an introduction to QCD, chiral symmetry, and the Standard Model. A special chapter is devoted to relativistic bound state wave equations an important topic that is often overlooked in other books. Clear and concise throughout, "Relativistic Quantum Mechanics and Field Theory" boasts examples from atomic and nuclear physics as well as particle physics, and includes appendices with background material. It is an essential reference for anyone working in quantum mechanics today.

In 1963, just three years out of veterinary school, Dr. John McCormack moved his wife and kids to Choctaw County, Alabama, to start his first practice. Choctaw folk never had a licensed vet before, and, with few exceptions, they welcomed the red-headed doctor and the tireless care he gave their animals. Fields and Pastures New is the heartwarming story of young Dr. McCormack's first years in this deeply rural country, where mule-drawn wagons still bumped down dirt roads . . . where the local barbershop was the best place to catch up on the news . . . and where nobody ever let Doc forget his most embarrassing moments. "I am proud to say that my closest friendships, outside my family, have been with my clients," Dr. McCormack writes. "I hope readers will get to know some of the workings of the small family farm, and how these down-to-earth people confront their hardships and disappointments with so much good humor.
