"How Big is Space and How Do We Know?" On Saturday, Nov. 15, at 7 pm, the Guilford College Physics Department will offer a public open house. Prof. Don Smith will share a multimedia presentation in our Joseph M. Bryan Jr. '60 planetarium dome and afterwards, if weather allows, we will ascend to the rooftop J. Donald Cline '78 Observatory for celestial viewing. A comet or two may still be visible! No tickets are required for this free event. Families are welcome. Handicapped accessibility is great for the planetarium, but limited for the observatory.
