Entropy and Time, by Sir'tyvaz Trisvaria
Have you ever wondered why time flows in only one particular direction in the material plane and many other planes of existence? To most of us this seems intuitive, time just is and it flows in one direction questioning it doesn't make much sense, if any at all. No one excepts a broken piece of glass to reconstruct it self without any outer influence, and I dare say no one has. Yet when we examine the laws of nature none of them dictates a particular direction for time explicitly, so how do we have such a strong intuition about that's always correct?
The answer is entropy. When you ask your local wizard about entropy he/she will say it's a quantity related to the number of possible states for a system and by observing it's change it's possible to conclude that change was spontaneous or not. Although this is correct it provides a very limited understanding to entropy. It is known for a isolated system entropy can't decrease, hence if we measure entropy of a system at random times, we can sort our measurements from past to the future giving us a direction for time! Change in Entropy is unique in that regard, it's the only law of nature we are aware that dictates a direction for time, it's an important concept not for only wizards and alchemists but for all of us, we are all bound to the flow of time.
