In this classic text, a Nobel Prize-winning astrophysicist presents the theory of stellar dynamics as a branch of classical dynamics--a discipline in the same general category as celestial mechanics. His method offers the advantages of clarifying the theory's fundamental issues and defining its underlying motivations. S. Chandrasekhar investigates two areas. The first concerns problems in which the time of relaxation of a stellar system is central. His method consists of analyzing the effects of stellar encounters in terms of the two-body problem of classical dynamics and applying this theory to the dynamics of star clusters. The second area investigates problems centering around Liouville's theorem and the solutions of the equation of continuity; here, the author discusses the dynamic implications of the existence of a field of differential motions, which appears to be the most striking kinematic feature of the galaxy and the extragalactic systems. This edition includes two papers by the author that were published after Principles of Stellar Dynamics and that have been studied and quoted extensively: "New Methods in Stellar Dynamics" (originally published in the Annals of the New York Academy of Sciences) and "Dynamical Friction" (originally published in The Astrophysical Journal).
What a splendid book! Reading it is a joy, and for me, at least, continuing reading it became compulsive. . . . Chandrasekhar is a distinguished astrophysicist and every one of the lectures bears the hallmark of all his work: precision, thoroughness, lucidity."—Sir Hermann Bondi, Nature The late S. Chandrasekhar was best known for his discovery of the upper limit to the mass of a white dwarf star, for which he received the Nobel Prize in Physics in 1983. He was the author of many books, including The Mathematical Theory of Black Holes and, most recently, Newton's Principia for the Common Reader.
In this monograph a leading modern astrophysicist explores a problem basic to stellar dynamics: What is the relationship between loss of energy, mass, and radius of stars in the steady state? The monograph is divided into two distinct parts. In chapters i-iv, Chandrasekhar presents the "classical" background necessary to his argument: the laws of thermodynamics (from Carathéodory's rigorous axiomatic standpoint), adiabatic and polytropic laws, and the work of Ritter, Emden, Kelvin, and others who developed the applied mathematics of stellar structure. Chapters v-xii discuss modern results: the formal theory of radiation, the equations of radiative equilibrium, the luminosity formula, the theory of stellar envelopes, Gibbs statistical mechanics (the quantum mechanical version), white dwarfs, etc. The closing chapter outlines some general trends in current investigations of the problem. Appendixes cover physical and astronomical constants; the masses of light atoms; the masses, luminosities, and radii of the stars, derived hydrogen contents, central densities and central temperatures, and tables of white dwarf functions. "Extremely interesting. It reaches the highest level of scientific merit." — Bulletin, American Mathematical Society.
This is a new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals, first published in 1977. The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications. This book presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals - the three classical types, nematic, cholesteric and smectic, and the newly discovered discotic type. Included is a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behaviour under external fields. The basic principles underlying the major applications of liquid crystals in display technology and in thermography are also discussed. This book will be of great value to advanced students and researchers in condensed matter physics, chemical physics, materials science and technology with an interest in the physics, chemistry and applications of liquid crystals.
Expanding upon the ideas first proposed in his seminal book Cosmical Magnetic Fields, Eugene N. Parker here offers the first in-depth treatment of the magnetohydrodynamic theory of spontaneous magnetic discontinuities. In detailing his theory of the spontaneous formation of tangential discontinuities (current sheets) in a magnetic field embedded in highly conducting plasma, Parker shows how it can be used to explain the activity of the external magnetic fields of planets, stars, interstellar gas clouds, and galaxies, as well as the magnetic fields in laboratory plasmas. Provocative and fascinating, Spontaneous Current Sheets in Magnetic Fields presents a bold new theory that will excite interest and discussion throughout the space physics community.
Temporal Bone Histology and Radiology Atlas provides a user-friendly approach to understanding both microscopic and radiographic anatomy of the temporal bone. It examines horizontal and vertical histologic sections and correlates them to the more commonly seen radiographic images, primarily on CT and also on MR. This enables the reader to "see" (by visualizing) much more when they look at radiographs than they otherwise would. This text is easy to use and can be referred to in detail as well as briefly and frequently in the course of otolaryngology or radiology practice, and can be digested comfortably for maintenance of certification (MOC) and Boards preparation. Key Topics: * Anatomical relationships * Fetal and postnatal development * Concerns doctors should have regarding radiographic images * Special preparation techniques for electron microscopy and DNA extraction Special histology techniques Temporal Bone Histology and Radiology Atlas is designed for otolaryngologists and radiologists in all phases of their careers, from medical school to residency and fellowship training to Boards to MOC and in ongoing practice. Neuro-otologists and neuroradiologists will benefit from this centralized compilation of information as well.
I say that this is a dirty, filthy book, and the test of it is that no human being would allow that book on his table, no decently educated English husband would allow even his wife to have ità." Such was the uncompromising pronouncement of Sir Hardinge Gifford, Her Majesty's Solicitor General, who in 1877 prosecuted Charles Bradlaugh and Annie Besant for publishing Dr. Charles Knowlton's Fruits of Philosophy.Knowlton's work was the first American medical handbook on contraception. It had become an incredibly popular book among Britons who believed the neo-Malthusian dictum that the only solution to poverty in Britain was a limit on the growth of its population. They saw effective birth control measures as a way to make such a limit practicable. In 1877, its publisher was hauled into court and pleaded guilty to printing obscene material. Bradlaugh and Besant tested the right of official harassment by bringing out an edition of the Fruits of Philosophy that bore an introduction explaining their motives. The pair was arrested and charged with violating the Obscene Publications Act of 1857.Their arrest, trial, conviction, and eventual acquittal constitute a landmark in the history of the world birth control movement. The enormous publicity accorded the principals and their cause brought the subject of family planning into the homes of nearly every Briton who read the newspapers' sensational coverage. What followed thereafter is telling: a dramatic, steady decline in the English birthrate. By their simple act of publishing Knowlton's short book, Bradlaugh and Besant helped establish England's pioneering role in the dissemination, democratization, and implementation of birth control information.Sripati Chandrasekhar is an internationally respected demographer and social scientist. He is a former minister of health and family planning in India and was vice-chancellor of Annamalai University in South India. He is the author of numerous books and articles on population and family planning.
This study surveys the level, causes, and course of infant mortality in India during the last seventy years. Besides this historical survey, the book examines the implications of high and low infant mortality on the country's major problems of population growth and the current population policy designed to reduce the birth rate through family planning. Originally published 1972. A UNC Press Enduring Edition -- UNC Press Enduring Editions use the latest in digital technology to make available again books from our distinguished backlist that were previously out of print.

First published in 1954, this reissue deals with the problem of international tensions arising from demographic and fertility differences, with special reference to such heavily populated Asian countries as China, Japan and India.
This text is easy to read yet comprehensive and a very useful guide to state of the art treatment of common conditions encountered by neurologists, otolaryngologists, and general practitioners. Common but challenging pathologies are discussed in detail in respect to etiology, diagnosis, and current management. Appropriate illustrations and tables are utilized to enhance comprehension.
First published in 1972, this reissue deals with the crucial issue of population explosion, one of the most crucial problems facing the contemporary developing world. Written by a world-renowned demographer and family planning specialist, the book deals specifically with the Indian experience. Reviewing population change in India over the last century, Professor Chandrasekhar focuses on three key issues: the socioeconomic repercussions of reduced infant mortality in twentieth-century India; the rapid population growth from 1871 and its implications on India’s efforts to raise her standard of living; and finally India’s valiant efforts to promote family planning amongst her hundred million married couples.
