Engineering & Te`chnology
Ever since the fabrication of the first laser in 1960, research and development in the area of optics has grown with tremendous rapidity. Optics has now become an extremely important area of study in schools, colleges and universities. Furthermore, because of numerous applications of optics, the United Nations General Assembly has proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015). There will be yearlong festivals associated with the International Year of Light. The present book (written primarily to enthuse young students to study more about light) is a part of the celebration of the International Year of Light.
About the Author:
Ajoy Ghatakdid his B.Sc., from Agra College, M.Sc., from University of Delhi, India and Ph.D. from Cornell University and was a Research Associate at Brookhaven National Laboratory. He joined IIT Delhi in 1966 and has recently retired from there as Professor of Physics. He is recipient of several awards including the 2008 SPIE Educator award, the 2003 OSA Beller award & the 1979 CSIRSS Bhatnagar award. He now spends his time writing books and doing guest lectures at schools, colleges and universities. He is author of several books including his undergraduate text on Optics which has been translated into Chinese and Persian. His other recent books are: Albert Einstein: A Glimpse of his Life, Philosophy and Science and Einstein and the Special Theory of Relativity [with DVD] – both published by VIVA Books in New Delhi.
