This BBC video above "Colorful Notions" from 1985 first summarizes the classical theory of color vision and follows with the ideas of Edwin Land who personally explains and demonstrates his experiments. It can be viewed as an introduction to this work.

Fastest Movie in the World Recorded: Method to Film Nanostructures Developed

A news item from SCIENCE DAILY today : Fastest Movie in the World Recorded: Method to Film Nanostructures Developed
This new capability seems to make it possible using pulses of x-rays to film motion in the sub-micron and femtosecond time domains. These are the spatial and temporal characteristics of the mechanism that I propose exists in the interaction of light with individual nano-antenna light detection sites at the plane of receptor outer segments on the retina of the eye. Specifically, this interaction involves: a.) the initial femtosecond light interaction event with the nano–antenna formed by the the apposition between two receptor outer segments, b.) a ”short term memory” or thermalization function provided by phononic (or what I believe to be solitonic) transport of the absorbed energy along the lipid membrane within the receptor, to, finally, c.) the isomerization event of the retinal molecule within the rhodopsin complex (that is known to occur in femtoseconds).
A diagram that I have used to illustrate the sequence of events in the nano-antenna ”quantized interaction” light absorption event:
One wonders if this near field femtosecond interaction might acutally be filmed? GCH Ojai,CA 1.14.11
