The title was made to be a bit enticing to the reader, the arrow of time we'll deal with in this post is the Psychological Arrow of Time . Imagine if the universe we lived in had no entropy at all. We wouldn't be subjected to the experience of the flow of time and grow old if we were in say Never-land, would we still have the ability to differentiate the past from the present? If everything seemed the same day in and day out? As a matter of fact, yes! Even in the hypothetical Never-land of ours, we'd be subjected to the experience of flow of time. This happens because of another interesting phenomenon called the Psychological arrow of time. This is how we inherently experience time, we differentiate between the past and the present because of things called Memories . They help us remember our actions in the past. Let's look at another interesting phenomenon, everyone knows we were once all babies, none of us remember most things about being one, hence that part of our p...

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...
