Описание:
The aim of this book is to present a self-contained, reasonably modern account of tensor analysis and the calculus of exterior differential forms, adapted to the needs of physicists, engineers, and applied mathematicians. In the later, increasingly sophisticated chapters, the interaction between the concept of invariance and the calculus of variations is examined. This interaction is of profound importance to all physical field theories. Beginning with simple physical examples, the theory of tensors and forms is developed by a process of successive abstractions. This enables the reader to infer generalized principles from concrete situations -- departing from the traditional approach to tensors and forms in terms of purely differential-geometric concepts. The treatment of the calculus of variations of single and multiple integrals is based ab initio on Carath odory's method of equivalent integrals. Subsequent material explores the effects of invariance postulates on variational principles, focusing ultimately on relativistic field theories. Other discussions include: - integral invariants - simple and direct derivations of Noether's theorems - Riemannian spaces with indefinite metrics The emphasis in this book is on analytical techniques, with abundant problems, ranging from routine manipulative exercises to technically difficult problems encountered by those using tensor techniques in research activities. A special effort has been made to collect many useful results of a technical nature, not generally discussed in the standard literature. The Appendix, newly revised and enlarged for the Dover edition, presents a reformulation of the principal concepts of the main text within the terminology of current global differential geometry, thus bridging the gap between classical tensor analysis and the fundamentals of more recent global theories.

Описание:
One of the greatest of all philosophical works, covering knowledge, imagination, emotion, morality, and justice. -- Baroness Warnock, The List Published in the mid-18th century and received with indifference (it fell dead-born from the press, noted the author), David Hume's comprehensive three-volume A Treatise of Human Nature has withstood the test of time and has had enormous impact on subsequent philosophical thought. Hume -- whom Kant famously credited with having interrupted my dogmatic slumber and gave my investigations in the field of speculative philosophy a quite new direction -- intended this work as an observationally grounded study of human nature. He employed John Locke's empiric principles, constructing a theory of knowledge to serve as a foundation for the evaluation of metaphysical ideas. Reprinted here in one volume, the Treatise begins with an examination of the nature of ideas: their origins and connections, modes and substance, and abstract qualities. The work's considerations of existence, knowledge, and identity explore the ways in which people use these concepts as a basis for firm but unproven beliefs. The second part surveys the passions, from pride and humility to contempt and respect, analyzing their roles in human choices and actions. The book concludes with a meditation on morals and an in-depth explanation of the perceived distinctions between virtue and vice. One of philosophy's most important works and a key to modern studies of 18th-century Western thought, A Treatise of Human Nature is essential reading for all students of philosophy and history.
Описание: A highly influential figure in the Age of Enlightenment in England and France, whose works helped inspire the Declaration of Independence and the U.S. Constitution, John Locke was one of the most important political theorists in Western history. In The Second Treatise of Government, a major contribution to the principles underlying modern democracies, he achieved two objectives: refuting the concept of the divine right of monarchy, and establishing a theory of government based on the ultimate sovereignty of the people. In A Letter Concerning Toleration, composed as early as 1667 but not published for political reasons until 1689 -- after the Glorious Revolution -- Locke pleaded for religious tolerance on grounds similar to his argument for political freedom, i.e., that all men are by nature free, equal, and independent, and are entitled to freedom of thought, freedom of speech, and freedom of worship. To help guarantee the latter freedom, Locke called for separation of church and state. The basis of social and political philosophy for generations, these works laid the foundation of the modern democratic state in England and abroad. Their enduring importance makes them essential reading for students of philosophy, history, and political science.
