The final level is just the average of the four initial stock values, since there is no
loss from the system.
This is a simple but profound view of the long-term processes of thermodynamics. While the system starts with low entropy (high differentiation), it ends with its
highest possible entropy (no differentiation). Show that with delays, this system can
be kept from this zero entropy state. The delays in a real system require an external
input of energy and this is the root cause of the system’s apparent reluctance to
dissipate.
Remove the two internal and one of the external flows. Does this truncated
system show the same result? Why? Compare the two systems through time.
