Murphy's Law and the Analogies of Physics

Murphy's Law is an adage that states: "anything that can go wrong will". It might be used as a muse or sometimes, given a sufficiently long time, an event which is possible will almost surely take place. Sometimes Murphy's Law is used in conjunction with thermodynamics (e.g. Second Law of Thermodynamics) which demands an understanding of the concept of entropy. Entropy is sometimes used in information science to describe the amount of information, for example, in a string of binary digits, but in thermodynamics describes number of ways a system may be rearranged (similar concept) but in the latter case, often taken to mean a measure of disorder. Ice melting is a classic example of entropy increasing.
