Patterns, Symmetry, and Crystallography topic of Science Colloquia

In the second lecture of the Fall 2009 Division of Science Colloquia, Dr. Daniel Litvin, Professor of Physics, will present "Patterns, Symmetry, and Crystallography" on Oct. 30, from 1-2:30 p.m. in Luerssen 123.

As the saying goes, no two snowflakes are identical-but snowflakes do share a symmetrical shape. Dr. Litvin will discuss how symmetry is the basis for the classification of crystal structure. The concepts of symmetry and groups of symmetry will be discussed in the context of two-dimensional Escher patterns and extend to the classification of two and three-dimensional non-magnetic crystals. A brief history of magnetic groups will also be given. Litvin will discuss his involvement in the classification of magnetic crystallographic structures and in the development of the scientific, pedagogical, and cultural aspects of the international crystallography community.

The Division of Science Colloquia features Penn State Berks faculty and visiting professors who conduct research on a wide variety of topics. Topics are of broad and general interest and are accessible to the non-expert.

Students, faculty, and members of the Penn State Berks and surrounding community are encouraged attend. This event is free and light refreshments will be served.
