**Title: ***Towers of Babel: What do probability, computer learning, combinatorial geometry, model theory, and neural networks have in common?***Abstract**: This will be a rambling talk that highlights a very attractive, naturally occurring polynomial/exponential growth dichotomy that keeps getting discovered over and over in various fields of math and computer science. Absolutely no knowledge of any of the fields mentioned in the title is assumed.

**Short bio:** Chris Laskowski is a professor of mathematics at University of Maryland. He is primarily interested in model theory, broadly defined. In addition to mathematics, he has co-authored papers in computational geometry, economics, and protein chemistry.
