From: Vladimir Trifonov Subject: SCI: Color-Vision Spacetime Date: Sun, 02 Jun 1996 17:35:44 -0400 Message-ID: <31B20930.3995@ix.netcom.com> Organization: MAA; Gamma Systems Research Group, Inc. Human Color-Vision "spacetime" is 1+3 dimensional (3 receptor types are responsible for the pattern formation, 1 - for its changing in time). A standard physiological fact (the identity of the neural mechanisms of vision and imagination in humans) makes one wonder if there is (research on) any connection with the "purely physical" concept of spacetime, the general concept of manifold, and, for that matter, the difficulties most humans experience trying to visualize higher-d structures.
