We are honored to announce our 2017 Keynote Speaker is Dr. Colin Bischoff.
Dr. Bischoff is a faculty member of the University of Cincinnati’s Physics Department studying Cosmic Microwave Background (CMB) using the BICEP telescopes at the Amundsen–Scott South Pole Station. CMB radiation was emitted shortly after the Big Bang. Dr. Bischoff hopes to detect a signal of primordial gravitational waves that are predicted by inflation, our leading theory of the conditions that produced the Big Bang.

The day is broken down into three parts:
displays by leading science, astronomy and technology providers, talks for novice and expert, tours of the historic buildings, safe solar viewing, telescope vendors, meteorites, kids’ activities, advice on buying and using telescopes, and more door prizes than you can imagine. Previous year’s exhibitors included iSpace, Stratus Helicopters, Tesla Motors, hands on science demos by UC Physics, Crystal Clear Science, Blue Chip Solar, Cincinnati Parks, Cincinnati Museum Center, the Cincinnati Astronomical Society and more.
Admission is Free. No reservations required.
