From the beginning of civilization, curious people have attempted to reduce our world to its simplest components. This search led scientists to discover the electron and culminated in the recent detection of the Higgs boson.

Our current model of the particle world is stunningly successful in describing the Universe as we know it. Yet we do not understand many of the underlying principles that shape the natural world. The nature of mysterious things such as dark matter and dark energy are as yet unknown to us.

At 3:30 p.m. Wednesday (March 8), Elliott Cheu will deliver a lecture entitled A Myriad of Particles in which he will describe the journey that has culminated in our current understanding of our Universe, while pointing to the discoveries that are yet to be made.

Elliott Cheu

The lecture is part of the Arizona Senior Academy’s encore presentation of the University of Arizona College of Science’s evening lecture series entitled Rethinking Reality. The Academy is pleased that Cheu, a Distinguished Professor of Physics as well as the Interim Dean of UA’s Honors College, has agreed to come to the ASA to give a reprise of his talk.

Cheu is a graduate of Stanford University who received his PhD from Cornell. In 2010 he received the Leon Blitzer Excellence in the Teaching of Physics Award. His current research is focused on use of the Atlas detector at the Large Hadron Collector to search for Supersymmetry and the physics beyond the Standard Model.
