John Nash and me: In memory of John Nash, Jr. (June 13, 1928 – May 23, 2015)

In the world of mathematics, everybody knows the name of John Nash, the 1994 Nobel Memorial Prize Winner in Economic
Sciences. I watched the movie 'A Beautiful Mind' in 2002. For most part of the movie, I almost believed that it was a real
story that he could decode the secrets of the military of formal Soviet Union before realized he had mental illness (paranoid schizophrenia).
I visited Princeton University in 2003 and found his office but not him.

Between AUGUST 26 - 27, 2005, I was invited to the "Workshop in Celebration of Bjorn Engquist's 60th Birthday: International
Forum on Multiscale Methods and Partial Differential Equations" at IPAM, UCLA. John Nash was an honorable guest in the
workshop as a colleague of Bjorn Engquist who moved from UCLA to Princeton. I met John Nash and his wife in person and
had a pleasant time and conversation for two days. He was a very nice, quiet, and polite person without too many words.  His wife
was much more talkative on the other hand. I was very glad to help him to log on to a UCLA computer to check his e-mails. John Nash
gave a public lecture about Game Theory during the workshop with the large auditorium completely occupied by the students and faculty of
UCLA, and other notables.
