Well it was first year calculus and transformations of X and Y axis as I tried to place city names on a map after a multidimensional scaling of city to city distances. Ah euclidean space now there's a thing.

I just today read John Nash's auto-biography on the Nobel prize web site. I don't see myself as a gifted in your face with my arrogant work type of paranoid schizophrenic. I am much more modest and just continue to produce my best. I am too beaten down by my science education from the 1970's that only featured male scientists and it is really my science education and socialization in the late 1990's and early 2000's that has brought a more gender balanced and racially balanced approach to the social world of science doing.
