I quite liked the summation of the Three Laws of Thermodynamics (can't remember by whom):

(for reference the three laws (paraphrased) are:

1. Energy cannot be created or destroyed
2. Entropy always increases over time
3. It is impossible to achieve absolute zero)


1. You can't win
2. You can't break even
3. You can't get out of the game

I'm perfectly calm. In fact, if I'm not calm, I may be slightly excited at the prospect of being able to claim some free money from the government :)

If you assert that nature tends to take things from order to disorder and give an example or two, then you will get almost universal recognition and assent. It is a part of our common experience. Spend hours cleaning your desk, your basement, your attic, and it seems to spontaneously revert back to disorder and chaos before your eyes. So if you say that entropy is a measure of disorder, and that nature tends toward maximum entropy for any isolated system, then you do have some insight into the ideas of the second law of thermodynamics.
