One of my lecturers in Signal Processing recently made the rather interesting
statement that : "if you can calculate a correlation matrix for a stochastic
process, then you know everything about that process".

An n by n correlation matrix contains the autocorrelations (dependencies)
of n stochastic processes.  An autocorrelator can be very easily constructed
from simple electronic components (integrator/threshold).

If anyone wants an alternative to the current "Can Machines Think"
argument, then they might like to develop the idea of the (human) brain
as a large autocorrelator of stochastic processes sourced from the senses,
noting that the autocorrelations between processes only become valid
as the number of observations made tens to infinity.
