Relativistic Quantum Mechanics. Wave Equations concentrates mainly on the wave equations for spin-0 and spin-1/2 particles. Chapter 1 deals with the Klein-Gordon equation and its properties and applications. The chapters that follow introduce the Dirac equation, investigate its covariance properties and present various approaches to obtaining solutions. Numerous applications are discussed in detail, including the two-center Dirac equation, hole theory, CPT symmetry, Klein's paradox, and relativistic symmetry principles. Chapter 15 presents the relativistic wave equations for higher spin (Proca, Rarita-Schwinger, and Bargmann-Wigner). The extensive presentation of the mathematical tools and the 62 worked examples and problems make this a unique text for an advanced quantum mechanics course. This third edition has been slightly revised to bring the text up-to-date.
This book is dedicated to the study of structure and transport of deep and bottom waters above and through underwater channels of the Atlantic Ocean. The study is based on recent observations, analysis of historical data, and literature reviews. This approach allows us to understand how water transport and water mass prop- ties have changed over the last years and decades. The focus of our study is on the propagation of bottom waters in the Atlantic Ocean based on new field data at key points. At the end of the 1920s, the first integral study of water masses and bottom topography of the Central and South Atlantic was carried out from the German - search vessel Meteor. This German Atlantic Expedition was one of the first cruises equipped with the newly developed echo sounder (fathometer): an obligatory p- requisite for the investigation of bottom morphology in the deep sea on an - erational base. The results of the expedition were published by Wüst, Defant, and colleagues in the multivolume METEOR publication series starting with the cruise report by the ship’s commander (Spiess 1928, 1932). Historically, this series of p- lications, intermittently interrupted by World War II, was the basis for many years of research into the development of modern concepts about Atlantic water masses and their circulation schemes.
As the Cold War began to wind down in the early '90s, former colonies were besieged by a string of humanitarian crises that killed millions of people and forced many more to leave their homes and livelihoods. This book shows how the international community, led by the U.S., responded to ten humanitarian crises.
Includes 8 illustrations. Field Marshal Horatio Kitchener, 1st Earl of Khartoum still stands as one of the great generals produced by Britain. His career was marked by great deeds, and great controversies. The son of a military family, he trained at the Royal Military Academy in Woolwich before his first trip to the Middle East surveying in Palestine in 1874. He joined the newly formed Egyptian Army in 1883, which was in reality controlled by the British, and embarked on campaign in Sudan. He was part of the failed Gordon relief expedition in 1884, and learned a great deal of the area, its people and the military problems of fighting in the arid desert. By 1892 he was Sirdar, head of the Egyptian army, he was given command of the expedition to crush the self-appointed Mahdi who had taken control of large parts of Sudan. It was during this campaign that he gained public and Royal attention after the victories of Atbara and Omdurman that crushed the revolt of the Mahdi. He served as Lord Robert’s second in command during the Boer War and served with distinction and much success, although his institution of concentration camps caused great outrage and awful civilian distress. Perhaps his greatest services were during the First World War, as Secretary of State for War, fashioning a great civilian army to fight the militarised hordes of Germany in France and Flanders. He may have gained even greater fame, but was tragically lost at sea when the H.M.S. Hampshire was torpedoed in 1916. An excellent short biography.
An examination of the Georgian city's complicated and sometimes turbulent development Savannah in the New South: From the Civil War to the Twenty-First Century, by Walter J. Fraser, Jr., traces the city's evolution from the pivotal period immediately after the Civil War to the present. When the war ended, Savannah was nearly bankrupt; today it is a thriving port city and tourist center. This work continues the tale of Savannah that Fraser began in his previous book, Savannah in the Old South, by examining the city's complicated, sometimes turbulent development. The chronology begins by describing the racial and economic tensions the city experienced following the Civil War. A pattern of oppression of freed people by Savannah's white civic-commercial elite was soon established. However, as the book demonstrates, slavery and discrimination, harassment, intimidation, and voter suppression galvanized the African American community, which in turn used protests, boycotts, demonstrations, the ballot box, the pulpit—and sometimes violence—to gain rights long denied. As this fresh, detailed history of Savannah shows, economic instability, political discord, racial tension, weather events, wealth disparity, gang violence, and a reluctance to help the police continue to challenge and shape the city. Nonetheless Savannah appears to be on course for a period of prosperity, bolstered by a thriving port, a strong, growing African American community, robust tourism, and the economic and historical contributions of the Savannah College of Art and Design. Fraser's Savannah in the New South presents a sophisticated consideration of an important, vibrant southern metropolis.
