Looking back, I now feel astonished at the immense patience with which he guided me when I first joined the lab with my embarrassing lack of knowledge about circuit design. Over the years, our discussions, ranging from circuit theory to Sartre and Hesse, have become a dear part of my life. In years to come, I will remember and cherish all our animated conversations, the joyous parties at his home, and Savita ma’am’s wonderful company.
