I was doing my MSc in the University of Madras in the year 2004-2006 and my M.Phil from 2006-2007 in the department of theoretical physics.
We got a splendid opportunity to learn physics from some the greatest mentor of that time. Prof Rajasekaran was one of them.
I attended his lectures on neutrino oscillation and string theory. It was an amazing lecture.
I still remember his classes, so vividly, he patiently clarified all my doubts.
Thank you Sir.
