It's almost as puzzling as Georg Cantor's Barber Puzzle!  If you are interested in reading more about the set theory behind the Barber Puzzle, please visit me at www.MathScienceHistory.com !  And while you're there, please feel free to buy me a cup of coffee, because every cup of coffee keeps my podcast up and running!  To purchase Hypatia: The Sum of Her Life, visit https://a.co/d/eU41Uun  Until next week, Carpe Diem!!
