Question

What is main reason for choosing physics as main subject..........?

Answer 1

The reason that I chose it as a main subject is because the fundamental questions of the universe seem to be able to be derived through physics. From the largest macroscopic scales to the smallest microscopic scales, physics is dominant. It provides a framework for us to be able to explain why the universe acts the way it does. Do we know the answer why yet? No of course not. We have to figure out what makes it that way before anything else. Do we know what makes it that way? That's a no as well. There is so much to figure out that your curiosity towards what makes everything run the way it does makes you helpless against the allure of the awe and wonder that is physics.

Answer 2

The secrets are within nature. The key to unlock them is mainly physics.
The reason I chose physics is... It's very simple, actually. So simple.
You can never know if it's true! Ever
