**Proving Prime Patterns**

The sequence of primes begins 2, 3, 5, 7, 11, 13, 17, 19… and seems at first somewhat irregular, even random. But looking at lists of thousands of primes some patterns seem to appear, such as the persistence of twin primes (pairs of primes differing by just 2). Are there really any persistent patterns? Is there a formula for the primes?

In this talk we will review some of what is known and what most mathematicians believe but none can prove. We will also discuss some wild speculations. Finally, I will explain how to apply some of the latest and most exciting discoveries to prove that a few of the apparent patterns are indeed persistent.
