Memories - a beautiful campus and an abstract - 27 years ago

I vividly remember that talk. 

People were great! Added bonus: the campus and the nature were amazing. 

I could recover my abstract from https://scholarworks.umt.edu/mathcolloquia/7/

 

So... about 27 years years ago:

 

Presentation Date 10-23-1997 

Abstract A classical problem considered by Davenport asks for the number of occurrences of a certain pattern of quadratic residues and nonresidues among the set of integers modulo a prime p. We will take this problem as a starting point of an itinerary revealing the interplay between quasirandom structures over finite fields, definable subsets of finite fields, character sums and coding theory.

The eternal paradox of neuroscience

"If the human brain were so simple that we could understand it, we would be so simple that we couldn't."
