The Mathematical Association of America (MAA) sponsors a slew of terrific talks and events each year, and recently they have begun to place digital versions of these online. This particular talk features observations from Google research scientist Kevin McCurley. In this talk from November 2009, McCurley focuses his presentation on the mathematics used to generate good search results and the more difficult task of coming up with "similar" results. Visitors to this site can read a brief description of the talk, and then listen to the complete lecture. Along the way, McCurley uses some illustrative examples, including discussing the results of a Google search on "mathematics". The site is rounded out by an interview with McCurley conducted by Ivars Peterson.
