Morgan is in the final crunch of finishing her dissertation draft, so

Chris's brother Steve Webber joins us for a special "nerdout":analyzing the dual nature of fuzzy vs crisp systems! From physics tobiology, from programming languages to human languages, the duality offuzzy and crisp is everpresent.

Yes, this really is what Chris and Steve sound like whenever they get

together...

  back in the day (but maybe it was?) but here's a more math'y breakdown of
  some of the ideas, To Dissect a Mockingbird: A Graphical Notation for the Lambda Calculus with Animated Reduction

• Duality (mathematics)

• Fuzzy and crisp sets

• Neats and scruffies

  (see also our previous episode about machine learning)
