a. on a macroscopic scale, a function of thermodynamic variables, such as temperature, pressure, or composition that is a measure of the energy that is not available for work during a thermodynamic process. A closed system evolves toward a state of maximum entropy.
b. in statistical mechanics, a measure of the randomness of the microscopic constituents of a thermodynamic system. Symbol: S
2) In Data Transmission and Information Theory: a measure of the loss of information in a transmitted signal or message.
3) In Cosmology: a hypothetical tendency for the universe to attain a state of maximum homogeneity in which all matter is at a uniform temperature (i.e. heat death).
4) a doctrine of inevitable social decline and degeneration.
The classic proof of First Cause is true: the caused cannot cause itself. Therefore, to observe, not only the self-initiated return to a former state, but an improvement in that state is an evidence of something truly supernatural. The resurrection of Jesus Christ is such a circumstance. Not only did he come back from death, he came back better--more powerful and not subject to death again.
One could dismiss such an occurrence because he or she was not there to see it. But for those who cannot shake eyewitness testimony, nor the need to explain the rise of Christianity in a hostile, pagan world, Christ's entropy-defying defeat of death and his return, not to zombie life but to eternal life, becomes the central event in human existence. Even more than that, it becomes the window to heaven and the gate to eternal life. Open up the shade and crack open the door, the world may offer zombiism at best, but light and life await you in Christ.
