Relativity :The special and the General theory
Albert Einstein is the unquestioned founder of modern physics. His theory of relativity is the most important scientific idea of the modern era. In this book Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory which has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einsteins immense contribution to human knowledge.In this work Einstein intended, as far as possible, to give an exact insight into the theory of relativity to those readers who, from a general and scientific philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. The theory of relativity enriched physics and astronomy during the 20th century.
Mysteries of the Universe [ASTRONOMY MUST-HAVE]
Answerable and Unanswerable Questions Does alien life exist? Is time travel possible? How did the Universe begin and how will it end? Is the future pre-determined? These are just some of the fascinating questions posed in this book which stretches across physics, the life sciences and cosmology. Each chapter considers a separate question and ends with either an answer or, if there is insufficient evidence, a ‘best guess’ answer. For every question addressed here—be it time travel, multiple universes, intergalactic travel, or the end of the world—the author has tried to exhaust all possibilities before arriving at a conclusion. Everyone will have their own opinion but one thing is certain— Mysteries of the Universe will fascinate, educate, and stimulate. DR PETER ALTMAN trained as a biochemist and now works as a science writer and speaker. His areas of special interest include cosmology, biochemistry and photography. He is the Founder and Chairman of the Bricket Wood Science Group and a member of the Magic Circle in London. I really like the premise of this book… The questions are just those that a lay person wants the answers to and the division into answerable and unanswerable makes a distinction that is not always apparent.

Industrial Electronics and Control
The third edition of the book on Industrial Electronics and Control including Programmable Logic Controller is aimed at providing an explicit explanation of the mode of operation of different electronic power devices in circuits and systems that are in wide use today in modern industry for the control and conversion of electric power. The book strives to fulfil this need for a fundamental treatment that allows students to understand all aspects of circuit functions through its neatly-drawn illustrations and wave diagrams. Several colour diagrams are included to explain difficult circuits and waveforms. This approach will help students in assimilating the operation of power electronics circuits with more clarity. Same as in previous editions, the book commences with a discussion on rectifiers, differential amplifiers, operational amplifiers, multivibrators, timers and goes on to provide in-depth coverage of power devices and power electronics circuits such as silicon controlled rectifiers (SCRs), inverters, dual converters, choppers, cycloconverters and their applications in the control of ac/dc motors, and heating and welding processes. The book also presents an overview of the modern developments in the field of optoelectronics and fibre optics. Finally, the book ends with a discussion on Programmable Logic Controller (PLC). The book has an added advantage of multiple-choice questions, true/false statements, review questions and numerical problems at the end of each chapter, designed to reinforce the student’s understanding of the concepts and mathematical derivations introduced in the text. The book is intended as a textbook for polytechnic students pursuing courses in electrical engineering, electronics and communication engineering, and electronics and instrumentation engineering. This tailor-made book with its exhaustive explanations of circuit operations and its student-friendly approach should prove to be a boon to the students and teachers alike. AUDIENCE: Polytechnic Students - pursuing courses in Electr
