It was a pretty incredible gift to be able to work with Kurt on this episode. His work spans decades and it took multiple tries to understand it in a way that could be put together in a narrative. I am very grateful for all of his time, warmth and generosity. I had to leave many, many wonderful pieces of research and factoids out due to time constraints but I would urge any of you that are interested to dive deeper into his work.
His colleagues Dr. William G. Ryerson, Ms. Amanda E. Hewes and
Ms. Sara Horwitz contributed a great deal to some of the research that I mentioned.
Dr. Margaret Rubega (rubegalab.uconn.edu/) deserves thanks for introducing me to Kurt in the first place.

  • I have been so happily watching these for the last, oh, year or two...but I just saw that little "are you human" ted talk and, surprisingly, teared up at one of them (something along the lines of "have you ever looked at someone you thought was totally ordinary and realized they were far more than that"), and then a few that followed....bravo.

  • I’m so glad you’re here to provide us with “True Facts,” zefrank; you’re a refreshing breath of fresh air after having listened to so many millions of ballsaques creating and posting “false facts,” “bad facts,” “untrue facts,” and other undesirable “non-facts.” And I love the way you do it with one of the most pompous, over-the-top fat-headed voices I’ve ever heard. I think you’d be a total blast to hang with, unless you speak in that voice all the time. I frequently imagine your wife trying not to drop anvils and other crazy-heavy objects on your head because you’ve driven her insane with your silly fake pompous voice. Thanks for everything you do; I love laughing while learning very cool (and true!) facts!
