Math Department ranking -- a dramatic increase!
The US National Academies periodically conduct a Data-Based Assessment of Research-Doctoral Programs. The ranking of Penn State's Department of Mathematics has risen dramatically. According to the previous assessment, in 1995, we were rated 37th nationally. The current assessment rates us approximately 10th or 11th! The detailed report is available at http://www.nap.edu/rdp/. (The new ratings are expressed in terms of confidence intervals. With 90 percent confidence, we are somewhere between 5th and 16th.) This dramatic increase reflects our efforts and accomplishments in research and graduate education.

Levi and Tabachnikov receive MAA grant for highschool math enrichment.
Professors Mark Levi and Sergei Tabachnikov have received the M. Dolciani Mathematical Association of America (MAA) grant. This grant is for projects designed to develop mathematical enrichment programs for talented students in middle schools or high schools. The goal of the program is to interest students who are ready for more challenges in the study of mathematics and encourage them to further their mathematical studies. Levi and Tabachnikov, in collaboration with G. Summers, a State High teacher, will run a biweekly mathematical physics club in the State College Area High School. The club's goals are to show student connections of mathematics with other sciences, primarily physics; to expose students to the unity of mathematics, exploring interrelations between algebra, calculus and geometry; and to demonstrate the beauty of mathematics, in particular, by solving challenging problems.
