On September 6th, Tina Sarawgi’s
Light and Sound class visited the Natural Science Center of Greensboro. Rather than having a typical lecture day, we got our weekly lecture from Rick Betton, the Director of Exhibits and Programs at the center. We were able to experience the center’s “OmniSphere Theater” and a few of its other attractions. Rick talked with us a lot about the science of light and how light can be mixed in different ways. He showed us how any color can be produced by combining a red laser, a green laser, and a blue laser; and if the laser moves across the screen fast enough, it can trick the brain into thinking that there is a solid image on the screen rather than just three different colored dots. A lot of the things Rick talked about related back to what we have been learning in class, such as the different effects and colors that can be produced by mixing light. It was interesting to hear about a different take on lighting from what we are used to and to view it from a scientific perspective.
