Murphy's Law is just Thermodynamics

I was sitting in my structural design class today, arguably the most intellectually challenging course I'm taking, and this thought pops into my head. Why it couldn't have chosen some time when I wasn't preoccupied I don't know. Murphy's Law is just thermodynamics. Allow me to explain...

The first law of thermodynamics says that the total quantity of energy in the universe remains constant. This is the principle of the conservation of energy. The second law of thermodynamics states that the quality of this energy is degraded irreversibly. This is the principle of the degradation of energy.

Essentially the second law is saying that without external influence, the disorder of any system will increase if left to itself. A cup of coffee on a table, for example, will cool down if left to its own devices - it will never spontaneously reheat.

When Murphy's law states "If anything can go wrong, it will go wrong", by 'wrong' it means 'not according to plan' or 'not as expected'. Plans and expectations, of course, are an imposition of order upon the world. Thus is should come as no surprise that their order will break down, as entropy increases.

Further to that, Murphy's law gains influence as systems increase in complexity. A round pebble, for example, is fairly simple, and Murphy's law is unlikely to have any effect on it so long as the plan is for it to remain a round pebble. Build a pyramid out of little round pebbles, however, and the chance of something going 'wrong' increases.
