This method allows the complete theory to be constructed starting from a small number of assumptions, and is the most natural approach in modern theoretical physics. The book begins by reviewing Newtonian mechanics and Newtonian gravity with the Lagrangian formalism and the principle of least action, and then moves to special and general relativity. Most calculations are presented step by step, as is done on the board in class. The book covers recent advances in gravitational wave astronomy and provides a general overview of current lines of research in

The book presents all the fundamental results on linear averaging dynamics, proposing a unified and updated viewpoint of many models and convergence results scattered in the literature.Starting from the classical evolution of the powers of a fixed stochastic matrix, the text then considers more general evolutions of products of a sequence of stochastic matrices, either deterministic or randomized. The theory needed for a full understanding of the models is constructed without assuming any knowledge of Markov chains or Perron–Frobenius theory. Jointly with their analysis of the convergence of

While FMEA is indeed a powerful tool to forecast failures for both design and processes, it is missing methods for considering safety issues, catastrophic events, and their consequences. This new book focuses on risk and HAZOP as they relate to major catastrophic events, safety, and risk. Specifically it addresses the process and implementation as well as understanding the fundamentals of using a risk methodology in a

Part of that obscurity may come from often impenetrable psychoanalytic language itself. The complexity of the subject matter has leant itself to a confusion of tongues and yet, at base, psychoanalysis remains an earnest attempt to make sense of and ease human distress.
