In the last post we talked about Time, specifically Arrows of Time and how they are different from each other. This post will be all about one of the directions of time or one of the arrows of time, that is: Thermodynamic arrow  of time. This is one of the Physics perspective of arrows of time. So let's get some basics out of the way: Entropy:  Entropy really helps us understand the Thermodynamic arrow of time. It is also often times really confusing  to understand entropy.  Entropy of any system is the measure of amount of energy which is unavailable to do work.  Two words that are important: Unavailability of energy and System. Let's look at them closely; Unavailability of    energy:  This just means unavailability of thermal energy or energy which can  be converted into work. This fits in perfectly with our topic "decay". As we go further into this it is  found that entropy of our universe increases (more on this later). Imagine ice w...
