Re: speed and specificity of enzymes

[Jerry Zhu <***>]

Tim,

You already give evidence that illustrates both
position and velocity measurements. You probably could
give more along this line.

Velocity measurement in 2nd order autopoietic system
has, in my mind, some to do with interactions between
neurons which I say second temporal symmetry breaking.
The first one is 2nd law of thermodynamics.  Is there
a third temporal symmetry breaking? yes. that is the
topic of 3rd autopoietic systems.
