Award winners to present McCoy Distinguished Lectures Nov. 19
WEST LAFAYETTE, Ind. Two Purdue University researchers in physics and mathematics will present this year's McCoy Distinguished Lectures on Tuesday (11/19).
Roberto Colella, professor of physics, will speak on "Multiple Bragg Scattering and the Phase Problem: Applications to Quasicrystals and Resonant Scattering" at 1:30 p.m. in Fowler Hall, Stewart Center. Alexandre Eremenko, professor of mathematics, will follow at 3:30 p.m. with his presentation, entitled "Meromorphic Functions and Intrinsic Geometry of Surfaces." Between the two talks, at 2:30 p.m., there will be a reception for Colella and Eremenko in Stewart Center, Room 218 C-D.
The lectures and reception are free and open to the public.
Colella and Eremenko are the winners of the 2002 Herbert Newby McCoy Award, generally presented to one Purdue student or faculty member for outstanding contributions to science. This year Purdue elected to recognize two researchers for their independent contributions to their respective fields.
The award was established in 1964 by Ethel Terry McCoy in memory of her husband, a Purdue alumnus. The winner is nominated by colleagues and selected by faculty representatives and the president of the university.
"The McCoy award is the most prestigious research award given by Purdue," said Charles Rutledge, interim vice provost for research and director of Discovery Park.
Colella's talk will concern methods of obtaining data on phase information in quasicrystals, materials that are neither amorphous nor crystalline in the traditional sense. It also will address resonant scattering, a new technique used to get information about the orientation of chemical bonds.
Eremenko's talk will concern meromorphic functions, which include most functions usually encountered in applications of mathematics to physics and engineering. Eremenko will discuss his success with Mario Bonk of the University of Michigan in solving an old problem about meromorphic functions that dates to 1935.
