Cafe Scientifique: Stephan Meyer, "Measuring the Big Bang: Still Confused After All These Years"
March 28, 2007 | 7:00 PM | The Map Room 1949 N. Hoyne
Website

Since its discovery 40 years ago, the fossil radiation from the Big Bang has been used unlock the secrets of the universe: how it came to look like it does today and what it is made of. As the measurements have gotten better, the picture has become clearer but not necessarily more understandable. Some of what we have learned is surprising and may be pointing to the fact that there is much yet to be learned (e.g., new physics). We will discuss the nuts and bolts of how cosmology measurements are made, what they tell us about the universe, and where this may be leading us.

Bruce Winstein, Panofsky Prize Talk: "Measurements of Direct CP Violation in the Decays of Neutral Kaons at Fermilab"
April 15, 2007 | 3:15 PM | 2007 APS April Meeting, Jacksonville, Florida
Website

For many years after its discovery, CP Violation appeared to be a phenomenon isolated from the rest of physics. The first goal was to see if tCP violation was due to a "superweak" interaction in neutral kaon mixing ("indirect" CP violation) or if there were a "direct" effect which would be manifest in the kaon decays themselves. For years, it seemed to be an interaction of the former kind, one that might not have any additional manifestations. A few years after the discovery, Sakharov realized that CP Violation in the very early Universe, in particular direct CP Violation, could lead to the matter-antimatter imbalance. A key development was the Kobayashi-Maskawa model which provided a framework in which to think about the problem, connecting it to quark mixing. This motivated a series of 2nd, 3rd, and 4th generation experiments to isolate the predicted direct effect. This talk will review how the problem was addressed in 3 Fermilab- based experiments spanning a 20 year period which culminated in a definitive detection of the effect by KTeV. The motivation and technical approaches to isolate this tiny effect with good control of systematic uncertainty will be reviewed together with the results and future prospects.

John Carlstrom, "The South Pole Telescope"
June 1, 2007 | 6:00 PM | LASR, 933 East 56th St, Chicago
Join us for a slideshow by Professor John Carlstrom, S. Chandrasekhar Distinguished Service Professor in Astronomy & Astrophysics and the College, about the telescope his team recently built at the South Pole. His research involves looking for clues in the cosmic microwave background that will unravel the mysteries of the nature and origin of dark energy.

South Pole Telescope Exploratorium Web cast
December 7, 2007 - January 18, 2008 | 10:00 AM
South Pole Telescope project collaborates with the Exploratorium to bring Live Web-Casts from the South Pole.

Dec 21, 2007: Join us as we talk with scientists working on the South Pole Telescope. In today's program, we'll learn about the various projects and teams of people on the project, how they work together, and how they analyze the data they receive.

Jan 18, 2008: In our final talk with the South Pole Telescope staff, we'll learn about data collection. We'll focus on the receiver, a very precise instrument that is a sensitive, state-of-the-art data collector with a thousand "eyes" pointed to the distant universe. We'll also meet the scientists who will be wintering over at the South Pole for eight cold, dark months.

Cafe Scientifique: Clem Pryke, "The Biggest Map in the Universe - the Afterglow of the Big Bang"
December 17, 2007 | 7:00 PM | Map Room, 1949 N. Hoyne, Chicago
Come and hear how scientists at the South Pole are making maps of the ancient Universe 80 billion light years across. These enormous maps are of incredibly cold light that once was too hot to handle, the Cosmic Microwave Background (CMB). The CMB is a faint radio hiss left over from a time when the entire Universe was hotter than the sun. Carefully mapping this now cold glow gives us a baby picture of the universe that reveals both its history and fate.
