CHFM Skyspace Presents a Talk by Phil Nelson, Ph.D.

Philip Nelson is a Professor of Biophysics at the University of Pennsylvania. His stimulating talk will focus on the intersection of physical light and retinal perception. While this is not a talk about the Skyspace, experiencing it has led many of us to wonder more deeply about visual perception. Dr. Nelson will explore how the question, "What is light?" leads us to deeper understanding of how we see, and also to some powerful new ways to see things. Dr Nelson is a widely published authority in his field who also wins kudos as a teacher able to make his subject relatable to the lay public. This is a speaker presentation / fund raiser.
