With current interest in extraterrestrials at a peak, this book is a collection of original and reprinted articles advancing the latest scientific ideas as to the possible existence and nature of extraterrestrial intelligent life. Usually this subject is treated only in popular media, such as science fiction novels, movies, and television. Recently, however, scientists and researchers have begun to consider in earnest whether extraterrestrials really exist, whether they have evolved from simpler forms of life, whether they have evolved intelligence, and if so whether their modes of understanding the world are comparable to and congruent with our own. The contributors to this volume cover these topics, and also consider how we might communicate with aliens, and whether we would be able to understand the alien messages we might receive. Finally the authors, who include distinguished scientists, speculate whether the aliens might have a moral code, and what might be our moral obligations in the event any extraterrestrials were ever discovered.

This volume undertakes a detailed analysis of the latest generation of learners' dictionaries of English. It assembles the papers delivered at the eponymous symposium held at the University of Erlangen-Nürnberg in April 1997. There are a number of reasons why these dictionaries are of special lexicographic interest: 1. the type of learners' dictionary associated notably with the name of Hornby can look back on a long tradition in British lexicography; 2. competition between various publishers since the late 70s has given crucial impetus to the development of these dictionaries; 3. these new dictionaries are decisively marked by the evaluation of large-scale computer corpora. Central to the volume is the in-depth comparison of four dictionaries published in 1995: OALD5, LDOCE3, COBUILD2, CIDE. The aim is to exemplify specific differences of approach in the four dictionaries from a wide range of viewpoints (definitions, information on valency and collocations, policy on usage examples, political correctness, etc.). A number of articles also enlarge on the history of learners' dictionaries of English, the significance of corpus linguistics for lexicography, and perspectives for the future, notably in connection with the electronic media.

Physicians diagnose and treat a host of conditions. Everyone who understands the nature of health care will be better able to participate in their own and their family's care. The Nature of Clinical Care explains the concepts underlying medical care. It provides everybody, including students, professionals and patients, with the know-how to participate in their own care. Approachable, straightforward, and insightful, it fills a crucial gap by addressing the patient-doctor relationship, how people make diagnoses, the purposes, benefits and risks of interventions, and the art and science of Medicine. It is a vast collection of helpful resources. As such, this compendium augments our knowledge base enabling and empowering everyone who must interact with the care system and its professionals.

Whiting wrote three seminal articles on general and theoretical aspects of paremiology, the study of proverbs and related speech forms. Friends, students, and colleagues from the Harvard English Department offer these essential readings to a new generation of scholars and enthusiasts of "the wisdom of many, the wit of one."

This unique volume presents the scientific achievements of Nobel laureate Philip Anderson, spanning the many years of his career. In this new edition, the author has omitted some review papers as well as added over 15 of his research papers. As in the first edition, he provides an introduction to each paper by explaining the genesis of the papers or adding some personal history.The book provides a comprehensive overview of the author's work which include significant discoveries and pioneering contributions, such as his work on the Anderson model of magnetic impurities and the concept of localization; the study of spin glasses, the fluctuating valence problem and superexchange; his prediction of the existence of superfluidity in He3; his involvement in the discovery of the Josephson effect; his discovery of the “Higgs” mechanism in elementary particle physics; and so on.The new papers added to this edition include ”Pressure Broadening in the Microwave and Infrared Regions” — a condensation of most of the author's thesis; ”Ordering and Antiferromagnetism in Ferrites” — the best-known of the papers written by the author involving what are known as “frustrated” lattices; and ”Localized Magnetic States in Metals” — a paper mentioned in his Nobel Prize citation along with localization and superexchange; to name a few.A Career in Theoretical Physics is an essential source of reference for physicists, chemists, materials scientists and historians of science. It is also suitable reading for graduate students.
