This year's Euler Lecturer is William Dunham the Truman Koehler Professor of Mathematics at Muhlenberg College. Bill's talk is titled Euler in Three Acts.
Abstract: In this talk, we recognize Euler's tercentenary with a three-part examination of his remarkable output.
Act I provides an overview of his work to suggest the depth and diversity of his life's achievement. Act II considers the 1737 derivation of the "Euler product-sum formula" and its use in proving the divergence of the reciprocals of the primes - arguably the birth of analytic number theory. Finally, in Act III we see Euler's evaluation of a non-trivial integral in which he cleverly enlisted the aid of two illustrious predecessors.
Taken together, these results indicate why Euler's 300th birthday is so worthy of a mathematical celebration.
