Speaker: J. Wehrley Chapman, Professor Emeritus of Physics (U-M Physics)

Professor Chapman will present the development of the ATLAS detector at CERN and the discovery of the Higgs particle. The experiment may be the largest scientific endeavor ever attempted with a total of 3000+ scientists and engineers engaged in building a massive detector which produces vast amounts of data. Professor Chapman will define the features of the detector, the volume of data, and the sifting of data to extract the long sought Higgs particle. We will see the pictorial view of sub-nuclear particles to illustrate how physicists view the world.
