I have been reading about quantum mechanics, which I do not pretend or presume
to "understand". I have been thinking about eye movements, in the experimental
study of which I was involved for about 6 months in a joint project of MIT and
Mass. Eye and Ear Infirmary. In retrospect I now consider that project to have
been fraudulent, frivolous and scurrilous. 

However, even today I remember some of the phenomena I learned about eye 
movements. The anatomic location and the functional focus of human vision
is the retinal fovea, which is a circumscribed locality of the central retina
which has a high concentration of sensory cells (cones, Netzhautkegel, 
Netzhautstab)
momentum-location
motion-place
time-space
The fovea is the only spot (section, portion, location) of the retina capable 
of imaging a pattern of small, closely spaced structures. The peripheral,
virtually spherical retina serves as a hemispheric scanning device which
merely ascertains the existence of objects and stimulates the rotation
or repositioning of the eye so that the object of interest falls on the fovea.
