Like physicists, mathematicians have always been divided into theorists and experimentalists. And, as with the physicists, the two groups of mathematicians have not gotten along very well. Still, in physics, there has always been an understanding that both groups are necessary, whereas during the past century or so, it has been possible to pretend that theorists are the only “real” mathematicians. I think this is a shame, and I hope both groups will try harder to get along.
