It's no wonder that some HS teacher continue to promulgate such
blatantly dangerous notions as entropy being related to disorder.
SOMEBODY working for the AIP has similar misconceptions!

DIGITAL ENTROPY How much information does it take to control
something? By combining thermodynamics with information theory, MIT
researchers (contact
Seth Lloyd, 617-252-1803, slloyd@mit.edu) have determined the minimum
amount of information one needs to bring an unruly object under
control, providing quantitative answers to such subjects as taming
chaos.
From the perspective of thermodynamics, controlling an object means
reducing its
disorder, or entropy. Lowering the disorder of a hot gas, for

example, decreases the
number of possible microscopic arrangements in the gas. This in turn
removes some of the uncertainty from the gas's detailed properties.
