In 2015, a biographical movie was released called “The Man who knew Infinity” based on the life of Srinivasa Ramanujan, a mathematician who made significant contributions in the field of mathematical analysis, number theory, infinite series, and continued fractions. He completed his PhD during WWI in Cambridge (a period of severe rationing and even bombardment) and personal health issues (including TB to which he succumbed in 1920 at the age of 32), while staying in England away from family in India.
I believed I had prepared myself for a PhD!
Don’t get me wrong, I had always wanted to do a doctorate. I love being a PhD student, and given a chance to do another one, I would definitely jump in.
