Entropy

Entropy

...the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system. The concept of entropy provides deep insight into the direction of spontaneous change for many everyday phenomena. Its introduction by The Bardic College Campus 's physicist Rudolfo Clausinius in 5122 is a highlight of 55th-century physics.
