S. Chandrasekhar – författare

Part of the reissued Oxford Classic Texts in the Physical Sciences series, this book was first published in 1983, and has swiftly become one of the great modern classics of relativity theory. It represents a personal testament to the work of the author, who spent several years writing and working-out the entire subject matter.The theory of black holes is the most simple and beautiful consequence of Einstein's relativity theory. At the time of writing there was no physical evidence for the existence of these objects, therefore all that Professor Chandrasekhar used for their construction were modern mathematical concepts of space and time. Since that time a growing body of evidence has pointed to the truth of Professor Chandrasekhar's findings, and the wisdom contained in this book has become fully evident.

Newton's Philosophiae Naturalis Principia Mathematica provides a coherent and deductive presentation of his discovery of the universal law of gravity. The Principia is, in fact, a model for all mathematical physics.Representing a decade's work from one of the world's most distinguished physicists, this major publication is, as far as is known, the first comprehensive analysis of Newton's Principia without recourse to secondary sources. Chandrasekhar analyses some 150 propositions which form a direct chain leading to Newton's formulation of his universal law of gravitation. In each case, Newton's proofs are arranged in a linear sequence of equations and arguments, avoiding the need to unravel the necessarily convoluted style of Newton's connected prose. In almost every case, a modern version of the proofs is given to bring into sharp focus the beauty, clarity, and breathtaking economy of Newton's methods. Chandrasehkar's work is an attempt by a distinguished practising scientist to read and comprehend the enormous intellectual achievement of the Principia. This book will stimulate great interest and debate among the scientific community, illuminating the brilliance of Newton's work under the steady gaze of Chandrasekhar's rare perception.

Newton's Philosophiae Naturalis Principia Mathematica provides a coherent and deductive presentation of his discovery of the universal law of gravitation. It is very much more than a demonstration that 'to us it is enough that gravity really does exist and act according to the laws which we have explained and abundantly serves to account for all the motions of the celestial bodies and the sea'. It is important to us as a model of all mathematical physics.Representing a decade's work from a distinguished physicist, this is the first comprehensive analysis of Newton's Principia without recourse to secondary sources.

Born in India, educated at the University of Cambridge in England, he served as Emeritus Morton D. Hull Distinguished Service Professor of Theoretical Astrophysics at the University of Chicago, where he has was based from 1937 until his death in 1996. His early research into the evolution of stars is now a cornerstone of modern astrophysics, and earned him the Nobel Prize for Physics in 1983. Later work into gravitational interactions between stars, the properties of fluids, magnetic fields, equilibrium ellipsoids, and black holes has earned him awards throughout the world, including the Gold Medal from the Royal Astronomical Society in London (1953), the National Medal of Science in the United States (1966), and the Copley Medal from the Royal Society (1984). His many publications include Radiative transfer (1950), Hydrodynamic and hydromagnetic stability (1961), and The mathematical theory of black holes (1983), each being praised for its breadth and clarity. Newton's Principia for the common reader is the result of Professor Chandrasekhar's profound admiration for a scientist whose work he believed is unsurpassed, and unsurpassable.

Conceived by Chandrasekhar as a supplement to his "Selected Papers", this volume begins with eight papers he wrote with Valeria Ferrari on the non-radial oscillations of stars. It then explores some of the themes addressed in "Truth and Beauty", with meditations on the aesthetics of science and the world it examines.

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.

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.

This book is based on two lectures given in Cambridge by Professor Chandrasckhar to mark the centenary of the birth of Arthur Stanley Eddington. The text describes Eddington's major contributions to astrophysics and to general relativity. The approach is not technical, although it will mainly be of interest to professionals in astronomy, applied mathematics and the history of modern astronomy.

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.

"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.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.

Asia's Population Problems (1967) features papers written by specialists – demographers, economists and sociologists – examining the various population issues facing different Asian countries in the decades following the Second World War. Population facts and policies, apart from affecting an individual’s happiness and security and a nation’s economic and social advancement, have come to play an important role in international relations. A proper understanding of demographic trends is key, and this volume aims to supply significant population facts and figures, and also provides the general national, economic and political framework of each country against which certain international demographic attitudes, approaches and policies may be understood.
