2025 Cantrell Lecture 2

The Riemann zeta function and the Riemann hypothesis

In Talk 1, we learned about some strange patterns in the prime numbers.  In this talk, we try to explain where these strange patterns come from.  This leads us to the Riemann zeta function.  
We also introduce an important open question called the Riemann hypothesis, and discuss how it relates to prime numbers and why it is hard to prove.
