Time The Physical Magnitude

In an age characterized by impersonality and a fear of individuality this book is indeed unusual. It is personal, individualistic and idiosyncratic - a record of the scientific adventure of a single mind. Most scientific writing today is so depersonalized that it is impossible to recognize the man behind the work, even when one knows him. Costa de Beauregard's scientific career has focused on three domains - special relativity, statistics and irreversibility, and quantum mechanics. In Time, the Physical Magnitude he has provided a personal vade mecum to those problems, concepts, and ideas with which he has been so long preoccupied. Some years ago we were struck by a simple and profound observa tion of Mendel Sachs, the gist of which follows. Relativity is based on very simple ideas but, because it requires highly complicated mathe matics, people find it difficult. Quantum mechanics, on the other hand, derives from very complicated principles but, since its mathematics is straightforward, people feel they understand it. In some ways they are like the bourgeois gentilhomme of Moliere in that they speak quantum mechanics without knowing what it is. Costa de Beauregard recognizes the complexity of quantum mechanics. A great virtue of the book is that he does not hide or shy away from the complexity. He exposes it fully while presenting his ideas in a non-dogmatic way.

Time decays form the basis of a multitude of important and interesting phenomena in quantum physics that range from spectral properties, resonances, return and approach to equilibrium, to quantum mixing, dynamical stability preperties and irreversibility and the "arrow of time." This monograph is devoted to a clear and precise, yet pedagogical account of the associated concepts and methods.

Featuring an exciting new chapter on several aspects of speech acoustics by Raymond D. Kent, PhD! With a new chapter, the classic textbook, Introduction to Sound: Acoustics for the Hearing and Speech Sciences, is back in a fifth edition and continues its aim to teach fundamental concepts of acoustics to students in communication sciences and disorders and related disciplines. Students of speech-language-hearing science must have a thorough understanding of the elements of acoustics before they can successfully embark on more advanced study of both normal and disordered human communication. The text is known for how acoustical concepts have been made understandable for all students, not just those who are already grounded in mathematics and physics. Coverage includes the nature of sound waves, simple harmonic motion, acoustic impedance, scales of measure, logarithms and antilogarithms, sound intensity and pressure, complex waves, resonance and filtering, distortion, sound transmissions, speech acoustics, and room acoustics. Key Features: * Summaries, Notes, and Practice Problems end each chapter * Bolded key terms throughout with end-of-book glossary * Alphabetical listing of selected equations * The numerous equations are displayed in blue for easier reading New to the Fifth Edition: * A new chapter, Basic Principles of Speech Acoustics, written by Raymond D. Kent, PhD * A special emphasis on editing the content throughout for increased readability and comprehension Please note: Ancillary content such as practice problems and acoustic animations are not included as in the original print version of this work.
