Robert McCloskey's _One Morning in Main_ is a charming story about a young girl
who looses her first tooth.  She runs around interpreting everything that she
sees in terms of her new experience.  Beautiful example of egocentrism.

Even adults have this problem.  Recently I read an article in Nature (February
23, 1995)  Pathway of processive ATP hydrolysis by kinesin by Gilbert, Webb,
Brune, and Johnson.  I am very interested in opponent-process.  Gilbert et al
reports that myosin and kinesin are binary switching in the microtubules.
These dimer actions I naturally see as opponent-process.  So the data curve
results in the classical values expected in the equation of the absolute
value of A process - B process equals the output.  The goal in opponent-process
is balance.  The data curve supports this with a ossilation of 50/50 hook up
of the myosin/kinesin system to the microtubules.  It is important to note
that there is considerable interest in the microtubules because the dimers
support quantum interactions and therefore the possibility exist for quantum
thought as suggested by Penrose and Hammeroff.
