Our ability to perceive the world and learn from our perceptions relies on our five basic senses. But did you know that 70 percent of sensory receptors are located in the eyes alone? This talk will take you through a visual tour of the Santa Catalina Mountains, discuss the science behind the physical phenomena that creates the colors you see, and reveal how new research may allow us to see our world in even better resolution. This is second of the five-part Summerhaven Speaker Series, presented by UA Science-Mt. Lemmon SkyCenter, July-November 2018, at the Chuck Bowden Mount Lemmon Community Center (also known as Summerhaven Community Center). The talks are free and open to the public and take place on the last Thursday of every month, July-November 2018.
