23: Nerdout! Fuzzy and crisp systems
44:52 Share

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 to biology, from programming languages to human languages, the duality of fuzzy and crisp is everpresent.

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