摘要:Mankind took many spectacular strides in the 20th century in the field of science and technology. Sending satellites to space without and with living beings, landing of man on the moon, mind boggling growth of information technology, experimentation in animal cloning, some extraordinary surgical techniques in transplantation of human organs, etc. It is said that many more new avenues are being explored in the 21st century. Nanotechnology is one of them. In some ways this technology has already made an entry in human life. The author of this article has tried to explain the changes that are likely to occur in living conditions of humankind. In fact this technology may usher in another major revolution in the lives of the human beings. Ishani experiences a sense of pride in publishing this article written by a distinguished Professor who has also been assigned with a special role in the field of Nanotechnology. The author of this article, Professor D.C. Kothari is Professor of Physics and coordinator of Nano Technology Centre in Bombay University. He also has many other feathers in his cap. We are mentioning some significant achievements in the biographical note given at the end of this article. Incidentally, it may be mentioned that Professor Kothari was one of the six recipients of a special cash reward of Rs 50,000 for best performance in academics and profession rendered to the University. Only a few months back, i.e., in the month of April 2008, this award was handed over at a special ceremony with the Chairman of Atomic Energy Commission, Professor Anil Kakodkar, as the chief guest. He handed over the awards to all the six recipients.
