### Our First Visiting Speaker for 2018-2019: Dr. Dennis Marks

Dr. Dennis W. Marks, Professor and Department Chair Emeritus at the Department of Physics, Astronomy, and Geosciences at Valdosta State University, will be giving a talk in our department on Friday, September 7. His talk, titled “Quantum Elements of Space and Time,” will be given from 2-4pm in 185 McCain Hall. His abstract is as follows:

Geometric algebras use matrices to describe space-times of any number of spatial dimensions and any number of temporal dimensions. Higher dimensions can be generated recursively (as matrices of matrices) from an element S of space and an element T of time. The properties of T show that time necessarily has an arrow of time. The element S is a quantum bit (qubit). A bit is a unit of information in one of two states, whereas a qubit could be in either state. Space is necessarily quantized, and quantum mechanics can be geometrized. Although relativity and quantum mechanics have different geometries, in 2-d they have the same geometric algebra, which serves as the foundation of all of physics. The Laws of Nature emerge as consequences of the uniformity of space-time. The uniformity of space-time is a consequence of its recursive generation.

We hope to see you there!
