Being a student of science in general and physics in particular, I tend to be one of the laziest persons professionally. I mean, I am serious! A theoretical physicist spends most of the time in his life reading, listening to songs, watching movies, gaming and most importantly sleeping. And oops I missed a vital point – discussing (read gossiping) with peers. And hence following the trend, I too spend a significant portion of my life thinking of useless issues (and posting them here).

One of the most fundamental questions that haunted me since I chose the field of physics was: why physics? And the most satisfying answer was its structure which made it so beautiful. By its definition itself (my version although) it tries to explain the most basic ways in the universe works. The most basic laws which make the universe the way it is. In a way it does a very vital job very simplistically. Let me explain my point with an example.

Consider the early ages, when man first started understanding the world around him. For him the world was full of facts and rules. That the sun rises from the east and sets in the west; that anything released from top falls downward; that periodically something (or someone) covers the sun so as to create night like conditions during the day were a few of them. Life was good for them but for a couple of problems. Firstly there were too many of laws to govern their lives (which is not too good if you think about it). Secondly, there was no way they could use nature to their benefit. This aspect was necessary for humans, because physically they were not in a position save themselves from the other animals or the disasters of nature. Here is where science (or physics) enters the scenes. People start realizing that day and night, falling objects and the solar eclipse are manifestations of the same law. This was a great discovery. A great reduction in the number of laws: from three (or presumably more) to a single one. Fabulous!

This in fact is an example of the way physics works. It seeks the simplest way in which to explain the working of nature. Today physics has advanced a great deal. With the help of mathematics it has simplified the structure of nature. But the goal remains the same: reducing the number of laws (or assumptions) that are needed to explain the nature of universe.

It would be very likely that the world around us would be very different than what is now. Why is the world the way it is? There has be a law which underlies the very existence of the form of nature. A law which superposes every other law. One law to rule them all…
