Tribute to Vikram Sarabhai

When I was very young, I remember people doing balloon experiments in the Indian Institute of Science campus, Bangalore. It was young Sarabhai with Homi Bhabha carrying out cosmic ray experiments. Vikram Sarabhai officially had registered for the Ph D degree of Cambridge University under the supervision of C. V. Raman, but his immediate guide was Homi Bhabha. Though I could not have known him at that time, I got in touch with him in 1961 when he was the President of the Physics Section of the Indian Science Congress. He had invited me to give a talk on Spectroscopy in Chemistry. After that meeting, we became good friends and met each other on different occasions.
