Sarabhai, pursuing his studies at Cambridge when WWII broke out, returned to India to work with CV Raman at IISc, where he also met Homi J Bhabha. In these excerpts from her […]
KP Sinha, a versatile physicist whose association with IISc stretches back almost fifty years, will turn 90 in July 2019 KP Sinha is an unusual man. Getting one PhD is hard work, but he chose to do two. And rare though it is for theoretical physicists to work in more than one field, Sinha mastered […]
Amogh Kinikar, who did his Master’s in Physics at IISc, on why graphene is a fascinating material In 2012, I found myself in the Department of Physics at IISc, holding a five-and-a-half feet tall, extremely top-heavy object called a dip stick. It was a long narrow vacuum chamber that could be inserted into vessels containing […]
