All those who like to have a constructively critical look at science and all its activities and all those who dearly expect science to be human and holistic in all its endeavours, I hope, will find this journey inspiring and informative. Main features of this book are as follow: (i) to show that science is neither the paradigm of absolute knowledge, rational and objective to the core, nor an enterprise where 'anything goes', with no rationality, no stability, no methodology and no objectivity; (ii) to show that both the rational and the non-rational models of science don't give the actual picture of science, as it is revealed and substantiated by the recent historians of science; (iii) to show the need to go beyond the traditional accounts of rationality in order to have an adequate of understanding of what happens in the realm of science, including the issues of rationality in science; (iv) to explicate some features of the notion of reasonableness and show how these factors, especially the notion of Consensus in the Scientific Community, which are usually neglected in the traditional accounts of science, need to be earnestly considered to arrive at an integrated understanding of rationality in science in terms of reasonableness; and (v) to bring out some of the implications of taking reasonableness seriously in the Cotemporary Science and Society.

2. Each chapter opens with necessary definitions and complete proofs of the standard theorems and results. These in turn are followed by solved examples which have been classified in various types and methods. This classification will help the students to revise the subject matter at the time of examination without losing any confidence. 3. Care has been taken not to omit even a minor step so that the students can understand everything without the guidance of a teacher. Hence even an average student will be able to grasp the subject matter easily. Furthermore, the problems have been graded in every chapter to instill confidence in the students. 4. Up-to-date yearwise reference of various examination papers have been given throughout the book. 5. At the end of each chapter objective type questions have been given in keeping with the latest trend of question papers. 6. This book serves as a suitable textbook, help book, reference book and question bank for all examinations.

that it is difficult for us to realize that their general acceptance in the transactions of commerce is a matter of only the last four centuries, and that they are unknown to a very large part of the human race today. It seems strange that such a laborsaving device should have struggled for nearly a thousand years after its system of place value was perfected before it replaced such crude notations as the one that the Roman conqueror made sustantially universal in Europe. Such, however, is the case, and there is probable no one who has not at least some slight passing interest in the story of this struggle. To the mathema tician and the student of civilization the interest is generally a deep one; to the teacher of the elements of knowlendge the interest may be less marked. This story has often been told in part, but it is a long time since any effort has been made to bring together the fragmentary narrations and to set forth the general problem of the origin and development of these numerals. In this little work the author has attempted to state the history of these forms in small compass, to place before the student materials for the investigation of the problems involved, and to express as clearly as possible the results of the labors of scholars who have studied the subject in different parts of the World.

Yet, many aspects about Earth's satellite remain unknown, and With an can keep scientists busy for years. In this book, S.K. Das sets out to explain some of them. How was the moon formed? Is the moon just a barren, rocky piece of land? Does it contain minerals that humans can use in the future? What does the dark side of the moon look like? India's maiden moon mission, Chandrayaan 1, set out to find the answers to some of these questions, among others. How did the Indian Space Research Organization go about planning for the mission; why did India need to go to the moon; are there going to be more space explorations by Indian scientists? Mission Moon is filled with lively descriptions of many little known facts and myths about the Moon. It also includes details of the Chandrayaan 1 project, including the recent, exciting discovery of water made on the Moon. Accompanied by photos from Chandrayaan 1's cameras, this book is for all young space enthusiasts and avid star gazers.

Publisher's Note: Products purchased from Third Party sellers are not guaranteed by the publisher for quality, authenticity, or access to any online entitlements included with the product. A cell phone's roaming feature allows the user to get service when traveling beyond the boundaries of his/her service provider. Wireless service providers make approximately 30% of their operating profit from roaming. But despite being a major source of income, roaming suffers from a number of technological problems in the handoff between networks. Signal strength is wildly variable, calls are frequently dropped, and quality of service is poor. Based upon training courses the author teaches at Agilent and Hewlett-Packard, this is the first book to give communications engineers the know-how to faultlessly design and manage roaming services.
