Despite callousness of society and political apathy, you continue your work with dedication, sincerity and determination. You endure hardships and make sacrifices for the sake of your work, simply because you are convinced that the only way to social betterment and nation building is through scientific knowledge and spirit. Heartfelt regards and salutations to all my friends who are striving hard to build a scientific India. Best compliments to all of you on the occasion of Vikram Jayanti!






I have always wondered whether the English word ‘nano’ has its origin in the Gujarati word nanu (નાનું = small) — the similarity is indeed remarkable. To explore the idea further, I opened the Merriam Webster dictionary and found that it is not so. The English word ‘nano’ has its origin in the Greek word nanos, meaning ‘small’ or ‘dwarf’.
My laboratory is situated in an isolated corner of the institute campus. Whenever I have to stay there in night time for some work, one or the other of the security guards turns up to check if everything is fine. That routine visit starts a scientific discussion and I find myself talking to him about lidar, sunphotometer, aerosols, dust, smoke and so on.
