Objects that differ from their mirror images, such as the left and right hands, play an important role in physics at all lengths scales, from elementary particles to macroscopic systems. The handedness, or chirality, of molecules in liquid crystals has a remarkable influence on the macroscopic physical properties of these systems, including the appearance of new phases. Indeed, the majority of optical applications of liquid crystals is due to chiral structures, namely the thermochromic effect of cholesteric liquid crystals, the optical activity in twisted nematic liquid crystal displays, and the ferroelectric and antiferroelectric switching of smectic liquid crystals.This book describes the main aspects of chirality in liquid crystals, and points out some of the open questions of current research. The chapters, each by an expert in the field, review the highlights of the important topics and representative questions in the field of chiral liquid crystals.

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.

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.

"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 ita." 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 volume contains the writings of Charles Knowlton and Annie Besant on reproductive physiology and birth control and an account of the Bradlaugh-Besant trial. Included also are two of Besant's own pamphlets on birth control, and a comprehensive introductory essay that establishes a context for understanding neo-Malthusianism and the advocacy of birth control in nineteenth-century England. One of a small handful of books that helped stimulate a women's movement in the West, it will interest sociologists and gender studies specialists as well as the general reader interested in the history of birth control.

Describes the main aspects of chirality in liquid crystals, and points out some of the open questions of current research. The chapters review the highlights of the important topics and questions.

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 new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals (1977) presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals--the three classical types, nematic, cholosteric and smectic, composed of rod-shaped molecules, and the newly discovered discotic type composed of disc-shaped molecules. The coverage includes a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behavior under external fields. The basic principles underlying the major applications of liquid crystals in display technology (for example, the twisted and super-twisted nematic devices, the surface stabilized ferroelectric device, etc.) and in thermography are also discussed.

Professor Chandrasekhar's work is an attempt by a distinguished practising scientist to read and comprehend the enormous intellectual achievement of the Principia without recourse to secondary sources. This text has stimulated great interest and debate among the scientific community, illuminating the brilliance of Newton's work under the gaze of Chandrasekhar's rare perception.

This is the third of six volumes collecting significant papers of the distinguished astrophysicist and Nobel laureate S. Chandrasekhar. His work is notable for its breadth as well as for its brilliance; his practice has been to change his focus from time to time to pursue new areas of research. The result has been a prolific career full of discoveries and insights, some of which are only now being fully appreciated.
Chandrasekhar has selected papers that trace the development of his ideas and that present aspects of his work not fully covered in the books he has periodically published to summarize his research in each area.
This volume is divided into four sections. The first, on dynamical friction and Brownian motion, includes papers written after Chandrasekhar published his 1942 monograph "Principles of Stellar Dynamics," Also in this section is "Stochastic Problems in Physics and Astronomy," one of the most cited papers in the physics literature, as well as papers written jointly with John von Neumann that have been given impetus to recent research. As Chandrasekhar notes, the papers in the second section, on statistical problems in astronomy, were influenced by Ambartsumian's analysis of brightness in the Milky Way. A third section on the statistical theory of turbulence addresses issues still unresolved in fluid dynamics, and the last section is devoted to hydromagnetic problems in astrophysics that are not discussed in Chandrasekhar's monographs.

This text provides a concise yet comprehensive review of common neurologic disorders. The pathophysiology, presentation, diagnosis, and management of these entities is discussed in detail in a clear, easy to understand format. The focus is on patients presented with vertigo, disequilibrium, hearing loss, pulsatile and non-pulsatile tinnitus, facial nerve weakness, and complications of the otitis media. Vascular tumors and anomalies, trauma to the temporal bone, Meniere's disease, as well as cerebellopontine lesions such as vestibular schwannoma and meningioma will be discussed with special emphasis on clinical applications. The appropriate diagnostic work up and treatment options as well as controversies will be discussed in the context of evidence-based medicine and "best practice" approach. Judicious use of MRI/CT scanning and audio-vestibular testing relevant for each pathology is discussed in detail. Appropriate illustrations and tables will summarize algorithms and protocols for managing these disorders making this text an easy- to-digest medical resource. A comprehensive reference list is provided.

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.

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.
