In this set of lectures, Jeremy Nathans explores the molecular mechanisms within the retina that mediate the first steps in vision. The first lecture focuses on the structure of the light sensing receptors, the intracellular signals that are triggered by light absorption, and the ways in which the retina extracts information from a complex scene.

WSM is used to mean the concept of matter really being fully explicable as spherical standing wave structures. By studying the possible actual structure forms we can understand how de Broglie's results make perfect sense and be in the company of de Broglie and Shroedinger who held to this view rather than one based only on probabilities.
