After reading Umesh article, I do recall many things, but it may need several volumes of books to write. Because, I was with him for the past 13 years and I can say it as a healthy and truthful relationship that I never had even with my age group friends. KSK is my model in personal and professional life. He made me explore science in conventional as well as unconventional ways. He is a good artist and nature lover. The name Krishnan was apt to him as he was always surrounded by a group of 2nd generation people for his pioneering thoughts. I could not bear his absence, but hope to continue my research following his ways. Missing him a lot...
