The second law of thermodynamics states that all natural processes proceed from law entropy to high entropy. So we only see an item drop to the floor from the table, instead of the same item flying upward. Of course if you'd argue with me that from the notion of statistical thermodynamics that we haven't yet seen it happen just because its probability of occurring is so low that we'd have to wait millions or even billions of years to witness all the consituent particles of that item flying above simultaneously. In etymology, "entropy" means "change inside." Therefore the word by itself doesn't indicate an idea of randomness. It only introduces us from macroscopic measures such as Energy(Q), Temperature(T)--those we can measure--to microscopic dynamics which we cannot perceive. If you still don't understand, let me cite an example from a real life scenario. A teacher gives some candies to a group of children, ordering them to distribute homogeneously. In other words the teacher intends every kid on the class to enjoy, without hierarchical difference. So you can imagine under normal circumstances, every kid will decide if he wants to impart some candies to the next kid based on whether he has more or not--if the next kid has more candies than you have, then it's he who should donate, instead of you. But what if certain anomaly emerges--a kid somehow accumulate, or hoard many candies? Initially we don't know why, but if we wish to explore the reasons, first we'd have to designate a measure with which to relate the "anomalous" kid to certain properties that is immanent or inherent to himself. That concept is exactly what causes the noun "entropy." The basic foundation of thermodynamics, or the zero-th law is heat always transfers from high temperature to low temperature. So if for each unit of temperature, some material can absorb ortransfer different units of energy, it is a property inside of itself! Now cut to the chase. Why some people can see ghost, or the so-called UFO-Unidentified Flying Object? Normally, we see things because those things exist first, then the light refracted from them is transmitted into our eyes , not the reverse. But for those who see unnatural phenomenon, the sequence is reversed--a apparition first appears inside their mind, and then projects onto the outside world! Can we explain this accident within the realm of physical science? Or we have to resort to the metaphysical? Assume that the ghost existence is an emergent property throughout the evolutionary process. It's not impossible but requires a long period of time to evolve. So you can see, our universe has evolved for billions of years, and only after living, conscious creatures appear, do this kind of highly improbable incident happens. (To be continued) --
