Cosmology is now a precision science due, in part, to results from the Wilkinson Microwave Anisotropy Probe (WMAP) satellite, launched in 2001, designed to measure the cosmic microwave background. The full sky photograph produced by the WMAP provides a detailed image of the universe at the point in its history when it first became visible. WMAP has measured the age, geometry, mass and energy content of the universe with high accuracy. We are now beginning to determine what happened in the first fraction of a second after the Big Bang, and a new generation of experiments should give us a detailed view of cosmic inflation. Dr. Tucker, a member of the NASA team carrying out this investigation, will present us with a current update on its findings. [Reception at 3:30 p.m. in CSB Lounge 110.]
