PUBLIC TALK: Mathematics and Statistics Colloquium

Followed by Cheese and wine in Maths Common Room

Abstract: We all have our doubts off and on if life is really so wonderful. But that is not what I want to address here. Watching the Jimmy Stewart movie with this title, there was one scene which captured my imagination: the Guardian Angel shows George Bailey how the world would have been without him. Personally, I never had much need to know how the world would have looked without me. However, all other things equal, how would life have been if I had lived in a different time and place, would be something of interest to me! This is the stuff of movies and fairy tales. But at least it is possible to play this as an intellectual game. I was born and raised in Germany before WW II. After getting my Ph.D. in 1962, I married a fellow mathematician and we immigrated to the US one year later, where we taught at a university until our retirements, first at Ohio State and then at Binghamton University. What would life have been if I stayed in Germany, did not get married, were born fifty or one hundred years earlier, or were born in another country? Looking at actual and potential role models over the centuries helped me answer some of these questions. In essence, it got me back to the roots of what shaped my life.
