Hello List Readers!

As my introduction, I think I'll just describe myself as a paleomechanic
and then leap into the fray. My understanding of entropy has always been
that it is very much a global concept rather than a local one. True, the
laws of thermodynamics predict a universal increase in the level of
entropy but at the local level of our planet, because of the flow of
energy through the system, you actually get an increase of order
(reduction in entropy) mostly due to the activities of life. Of course
this energy flow won't continue forever. When the sun eventually fades
away, then the true course of the universe should re-assert itself.

However, if you subscribe to the oscillating universe theory, once the
Universe contracts back in on itself, we get lots of energy flowing
through systems again and plenty of chance for more increases in order -
so we won't permanently be out of jobs :->.
