PHYSICS INTRODUCTION

WHAT IS PHYSICS ?

             Physics has been derived from the Ancient Greek word " phusikḗ " which means " knowledge of nature "  . Physics is the study of nature. The way things connects one another.  These connection are underlined by concepts. and those concepts are beautifully expressed in mathematically.

             Each and everything happen in our real world has a secret behind it. Like we wake up and see sun light is all over and when day passes it vanishes and the same thing happen next day , how?  We see some flowers are looking red some are white, how? When we push a thing it moves away, when we pull thing it comes towards, why? If we go nearer to sun we feel mot hot, but at the top of the mountain we feel cold, as the mountain is more close to sun than ground. why? A rocket falls down but satellite does not why? There is a secret behind everything happen in our universe. 

           " The universe is full of magical things patiently waiting for our wits to grow sharper. Physics is the gateway to those magical things. "

             Consider a smart phone.Physics describes how electricity interacts with the various circuits inside the device. This knowledge helps engineers select the appropriate materials and circuit layout when building the smart phone. Next, consider a GPS system. Physics describes the relationship between the speed of an object,the distance over which it travels, and the time it takes to travel that distance. When you use a GPS device in a vehicle, it utilizes these physics equations to determine the travel time from one location to another.

IS IT REALLY IMPORTANT TO LEARN PHYSICS?

            

             Assume you and your mom watching a base ball match, you are really enjoying the match , and your mom feeling bore as she has no idea about the rules of the match. So your mom did not appreciate the match. To enjoying something or to appreciate something you must know the rule behind it. And physics is the rule of nature. If you know the rule of nature you will alive what is going around you. Physics will help you to appreciate the world more.

Life is physics.Every truth, known or unknown, is physics. The best illusion, the most awe-inspiring phenomenon, is physics. It is the foundation on which every one of our achievement, our understanding is built on. After all, the universe is physics! 

 In the beginning i ask " what is Physics? " I was wrong.  The real question is "what is not physics?" . Every thing is all about physics .
