What do sunglasses, barcodes, and Blue-Ray discs all have in common? Lasers and Optics! Lasers and optics are all around us. The University of Nebraska State Museum will host a Sunday with a Scientist program for children and families to learn about light, lasers, and optics from 1:30-4:30 p.m. March 20 at Morrill Hall. Scientists in the UNL Department of Electrical Engineering will provide fun, hands-on activities and demonstrations to help visitors learn how lasers and optics work and impact our lives.
