cooler that heats; Turing up a level? -Reply

... Incidentally, I am trying to revise my old tutorial posting on
entropy, putting it more in a control-system context. With luck, it
will result in a posting before long.

Looking forward to it.

Rick will think it is putting a theoretical cart into a place where
there are no horses, but then he doesn't see that the cart uses one
of M. Carnot's magic engines.

Rick sometimes forgets that one needs a well developed theory before
one can do The Test, and that if you _like_ to do The Test, you need
those theories.

Rick also tends to forget that theories, well developed or not, are
necessarily based upon observations; one might say that a theory is
an abbreviation, a succinct description, a cross-section of a number
of perceptual events. In that sense, every theory is grounded in
reality. And if interesting enough, worthy of our consideration.

But then much depends upon what we find interesting...

Greetings,
