After the lecture, when all of us students went to shake hands with him, something happened that I will remember the rest of my life. He spoke to ME! But, Alas!, not on anything technical. I had worn a shirt with a big Ferrari logo. When it was my turn to shake hands with him, he said looking at my shirt: "You have a Ferrari?"
I said, "No , Sir..."
"Well.... Win the Nobel prize and you can buy one!"
(Pauses for a while) "Oh! You cant buy a Ferrari with that! You'll have to kill the other two laureates!"
Well, I would be prouder, if we spoke on something else. But, If at all I DO win the Nobel Prize, I will certainly quote this incident in my Nobel speech.
