*Proofs and Confirmations*, and has been a Pólya Lecturer for the MAA. He is a recipient of Macalester's Jefferson Award. He has published over fifty research articles in number theory, combinatorics, and special functions. His other books include

*Factorization and Primality Testing*,

*Second Year Calculus from Celestial Mechanics to Special Relativity*,

*A Radical Approach to Real Analysis*(now in 2nd edition), and, with Stan Wagon

*, A Course in Computational Number Theory*. His latest book,

*A Radical Approach to Lebesgue's Theory of Integration*, is due out by the end of 2007.

David chairs the MAA special interest group, Teaching Advanced High School Mathematics. He has chaired the AP Calculus Development Committee and has served as Director of the FIPSE-sponsored program Quantitative Methods for Public Policy.
