For the past twenty years, Infinity Foundation based in Princeton, USA, has pioneered many areas of research concerning India?s civilization. Among these has been the 20 volume series on the History of Indian Science and Technology, of which this volume is a part. It policy has been to work with world class scientists, archaeologists and historians to produce works at the highest standards. India has a glorious past in various spheres of social and economic development. Indians have been the pioneers in Mathematics, Astronomy, Medicine, Neuroscience, Taxonomy, Yoga, Architecture, Water Management and a number of similar areas. However, most of that has been either misrepresented or has remained shrouded under a well-thought strategy of those who were inimical to the India?s glorious past. What is being ignored is the well-documented corpus of India?s significant contributions in fields of Science and Technology.
