Secrets of Mental Math

Speaker: 

Professor Arthur Benjamin

Institution: 

Harvey Mudd College

Time: 

Thursday, January 12, 2012 - 12:00pm

Location: 

UCI Student Center, Pacific Ballroom C

The Mathematics Department at UCI, with the support of NSF RTG grant DMS-1044150, is proud to present "Secrets of Mental Math," a breathtaking show by the great mathemagician Dr. Arthur Benjamin.

The event is part of a math seminar series for undergraduates and will take place on January 12th from 12 to 1 p.m. in Pacific Ballroom C, at the UCI Student Center. The event is free and open to the public.

Dr. Arthur Benjamin is both a professor of mathematics and a magician. He has combined his skills to create a dynamic presentation called "Mathemagics", suitable for all audiences, where he demonstrates and explains his secrets for performing rapid mental calculations faster than a calculator. Dr. Benjamin has presented his high energy talk for thousands of groups throughout the world, including many colleges and universities. He has appeared on many television shows and radio programs, including: The Today Show, CNN, The Colbert Report, and National Public Radio. He has been profiled in The New York Times, Los Angeles Times, USA Today, Scientific American, Discover Magazine, Omni Magazine, Esquire Magazine, People Magazine, Wired and Reader's Digest.

Dr. Benjamin received a standing ovation when he presented part of his show at the TED 2005 meeting. Since the talk went online, it has been viewed over a million times. Reader's Digest calls him "America's Best Math Whiz".

Solving an inverse obstacle problem for the wave equation by using the boundary control method

We consider boundary measurements for the wave equation on a bounded domain $M \subset \R^2$ or on a compact Riemannian surface, and introduce a method to locate a discontinuity in the wave speed. Assuming that the wave speed consist of an inclusion in a known smooth background, the method can determine the distance from any boundary point to the inclusion. In the case of a known constant background wave speed, the method reconstructs a set contained in the convex hull of the inclusion and containing the inclusion. Even if the background wave speed is unknown, the method can reconstruct the distance from each boundary point to the inclusion assuming that the Riemannian metric tensor determined by the wave speed gives simple geometry in $M$. Computationally the method consists of solving a sequence of linear equations. We present some numerical results.
