Friday Geeky T-Shirt Blogging: Entropy. It Ain't What it Used to Be

I think of all my geeky t-shirts, this one is my favorite. For me these eight little words are not just chuckle-worthy, they say so much more than what is apparent.What is entropy? Without going into a thermodynamic treatise on usable and unusable energy, I will say that entropy is simply the disorder or randomness in a system. The higher the entropy the more disorder there is. Without adding anymore energy, the entropy of a system will increase but not decrease. For example, if I knock over a glass and it shatters on the floor, the entropy has increased. The glass is very disordered laying on the floor in a bunch of pieces. The glass will never spontaneously reassemble. That would require a decrease in entropy. The only way to decrease the entropy of the glass is to add energy: the energy required to collect all the pieces and glue the glass back together.The Second Law of Thermodynamics states the entropy of the universe is increasing. As time goes on, the universe is becoming more and more disordered. Hence the "Entropy. It ain't what it used to be."But entropy has theological implications. If the universe is becoming more disordered, then at some point, in the beginning, it was infinitely ordered. In the beginning. Perfect order. I don't know about you, but to me that screams, "Creator!"Dr. Robert Jastrow, in his book God and the Astronomers, wrote:"Theologians generally are delighted with the proof that the universe had a beginning, but astronome...
