Disaster Management is relatively a new discipline in our country. Truly speaking, a few decades ago, the administration and the government machinery in India had no clear concept of Disaster Management, leave alone its execution and implementation of corrective measures.

Ironically, it was the alarm given by natural calamities like cyclones and earthquakes which awakened our authorities and policy planners. However, now concern, regarding the problem and related matters. Obviously, there is a dearth of good books on the subject. This research based and authentic work should fill the bill.

This encyclopaedia covers all aspects of Science, from definitions of technical terms to characterization of different fields. This volume provides wide-ranging exposure of biology, chemistry, physics, earth sciences, astronomy and all other fields of science. Entries include areas such as astronomy, earth sciences, solar system, genetically modified organisms, plastics, electronics, cell biology, and theory of science, history of science, sociology of science, scientific metering, and economics of science, mathematical and cybernetic methods of analysis information, system analysis, scientific institutions and methods of scientific forecasting. Articles on leading scientists are also covered. From the basic elements of theory to the most cutting-edge technology, all is explained in this volume.

A number of reference works have been published in recent years that include, but are not restricted to, biographical information about scientists. This volume is designed differently and is intended to meet several specific needs. It provides personal and professional information concerning scientists, including some whose accomplishments are undeservedly obscure. We have included scientists from Academics and laypersons, professionals and amateurs, all are figured in this volume.

This Encyclopaedic Dictionary of Science is an effort to keep pace with continuing rapid developments and expanding vocabularies in various branches of science. This dictionary has been encyclopaedic in its contents and style of representation. Throughout the process of compilation and editing the volumes, the main effort was to make the dictionary serve as a ready reference for undergraduate and postgraduate students of science and for those appearing for competitive examinations, research scholars, teachers and authors. The entries have been written in a clear and explanatory style to provide both straight forward definitions and invaluable background information. This approach, combined with an extensive cross-reference system, enables the reader to place the each entry into a broader scientific context. At certain appropriate places, the diagrams have been included whenever the meaning of a word can be best understood by means of a diagram. The presentation throughout has been aimed at sustaining the interest of readers while enriching their vocabulary and comprehension of technical terms and expressions of various branches of science. This encyclopaedic dictionary will be of immense value to the students of science and to scientists and research scholars working on science projects.
