Color Physics @Hampshire, Day 13

On day 13, a guest speaker, Prof. John Castorino gave a lecture on the biology of color vision.  His presentation included an introduction to the anatomy of the eye, the placement of rods and cones, their response to the sensory input, the mechanism behind trichromacy of color vision, the biological basis for color blindness, and many more (I am certainly missing a number of topics). It was great for students to be able to ask biology-related questions and get a straight answer.
