Sigma Xi lecturer to discuss the structure of matter April 5

Learn more about the structure of matter at the annual Tennessee Tech University Sigma Xi lecture set for Thursday, April 5, at noon in Clement Hall 212.

This lecture is free and open to the public.

Discussing "The Level Structure of Matter" will be Ronald E. Mickens, the Distinguished Fuller E. Callaway Professor of Physics at Clark Atlanta University. He received his Ph.D. in theoretical physics from Vanderbilt University and has held postdoctoral positions at the Center for Theoretical Physics-MIT, The Joint Institute for Laboratory Astrophysics, and Vanderbilt University.

Science is possible because the various phenomena of the physical universe, to a very good approximation, can be compartmentalized," explained Mickens. "Thus, phenomena in a given compartment can be studied essentially independently of those in other compartments. These compartments are generally conceptual in nature and are associated with particular space and time scales."

Mickens's current research interests include such topics as the mathematical modeling of periodic diseases and the history/sociology of African Americans in science. He has published more than 200 research papers, written five books, and edited five volumes.

Professor Mickens serves on the editorial boards of several research journals including the Journal of Difference Equations and Applications. His professional memberships include the American Mathematical Society, the American Physical Society (for which he is an elected Fellow), the National Society of Black Physicists and the Society for Mathematical Biology.

The national organization of Sigma Xi was founded in 1886 as an honor society for science and engineering. Today, it is an international research society whose programs and activities promote the health of the scientific enterprise and honor scientific achievement.

There are more than 80,000 Sigma Xi members in over 500 chapters at colleges and universities, industrial research centers and government laboratories. The Society has its headquarters in Research Triangle Park, North Carolina.
