"ऐसा हो सकता है कि हम-तुम अब वर्षों दूर रहेंगे, लेकिन, याद रहे, उसी स्त्रोत - पिंड भास्कर से दोनों ऊर्जित - सिंचित रहेंगे।" - Words from Prof. Sameer Khandekar's Poem "Kaal Chakra Pravah"
The first day I met him, he fit well into my typical impression of a Professor (thanks to Albert Einstein). His approach towards life was simple, "do whatever you like, but once you decide the path, follow it confidently & tirelessly". His words were always reassuring to a student who was often found anxious about his research results in the lab. An artist within, he had a deep interest in Indian Classical Music, & could often be found sitting in the front row during the SPIC MACAY performances in the IIT Kanpur auditorium. His keen observation & fascination with visually appealing symmetries often pushed the student to put in some extra effort to learn & convey dense information through beautiful & easy-to-understand schematics.
My experience of him has enriched my life with the idea of a true Professor and an ideal supervisor. He taught me 'Heat & Mass Transfer' in my 3rd year. At the start of every lecture, the whole batch of ME used to wait for "what prototype is he going to bring in the class today". As a true experimentalist, there was hardly any lecture of that course in which he did not bring any apparatus/specimen - in the hope that at least a few of the students could have "ignited minds" by the end of the course. I do remember a few things that created ripples in my technological subconscious- the thermochromatic liquid crystal films, the specimen of gold thermal protection shield used in rockets, and an experiment to justify the lumped system model in heat transfer. Even during the COVID days, as the instructor of 'Refrigeration & Air Conditioning', he used to give continuous motivation through his unconventional mails (invoking the 'jawans at the border' several times) for the demotivated us.
As the dust of COVID started settling down & the campus started opening up, my excitement to meet him in his new role - as my supervisor - made me restless. Once we started going along, his perspectives & methodology made me awestruck. The lab he nurtured was perhaps one of the best in the whole of IIT Kanpur, not just in terms of the facilities & equipment, but also in terms of the culture. It is often said that a team is the reflection of its leadership. And here was a leader who knew no obstacles when it came to experimental research. His out-of-the-box ideas of conducting experiments could often beat the creativity of any young mind. His work ethic was unparalleled, & the amount of hard work he put into any of his commitments was exceptional. In the middle of one of the nights, when I was busy conducting experiments in the Phase Change Thermal Systems Laboratory, I found him hustling into the lab at around 12.30 am to complete his commitment towards, probably, a book. While I continued with my experiments throughout the night, I was awe-struck by the level of dedication shown by him. He was awake for the whole night, going back to his home at around 4 am, only to come back to the office & take lectures at 10 am that morning.
As a Teaching Assistant in his course, his trust in me to sort things out made me realize that gaining trust is, perhaps, the most important virtue that lies at the foundations of any human endeavour. Often the students had diverse views on issues of academic importance, but his accommodative & understanding nature was yet another defining feature of him. Rightly so, he was much concerned about the degrading student-teacher relationship as a universal phenomenon across the nation. He was firmly against the rising student perception of their teacher as just a 'service provider'. His concern continues to be serious in the present times, where the commodification of anything & everything is raging across the world, not even leaving the purest of the professions - the academia. He used to give me a lot of guidance not just on the technical aspects, but also on life. Whenever my experiment & simulation results did not come as expected, he was always there to give me a pep talk.
On one of my last days with him in the lab, he asked me whether I had enjoyed whatever I did in the lab or did it seem like a load. My answer was the former, & the contentment on his face (perhaps, owing to his yet another success in his definition of 'supervisor') was clearly discernible. He was my Professor and will always remain so.
May Maa Saraswati give Pradnya ma'am & my friend Pravah the courage to bear this tragic loss. May we continue getting inspired by his attitude towards mechanical engineering, technology, nation, & life as a whole. Om Shanti!
