Dennis Wildfogel first taught calculus over forty years ago. He received his Ph.D. from the University of California, Santa Barbara under the direction of Prof. Ky Fan.
In case you’ve seen my “How Big Is Infinity?” video, thought I’d tell you a bit about my personal connection to that topic. As mentioned in the video, I first heard about the idea of matching different infinite sets when I was in fourth grade. I certainly did not get it all then. As a senior in high school, I had a class that went through this material and I was gratified to finally be able to understand it. More amazingly, that summer, 1963, I read in the newspaper about Paul J. Cohen’s work, which had just been published – right after I had learned about this stuff (right up to but, of course, not including his work)! Then five years later, as a graduate student, I had a class from Prof. Cohen and had the good fortune of being able to speak with him on several occasions.
