What is ‘Physics’?


What is ‘Physics’?

We are just going to begin a long journey through what we call ‘Physics’ as Advanced Level students. Actually, ‘WHAT IS PHYSICS?

What is the first thing that comes into your head when you hear the word ‘Physics’? Is it something like a force or an engine? Or else is it some sort of a high-tech super computer or a space lab orbiting around our Earth in outer space? Maybe, let me think, is it a nano robot travelling through your blood stream to kill cancer cells or is it the unreachable helium core of the Sun where that amazing proton – proton cycle is always functioning, giving the entire solar system life and energy? Is it a simple toy in your nursery or a steam engine?

Whatever which comes into your head first, there is always ‘something’ which is familiar to us that uses the fundamental principles and theories of physics. So, simply physics is a branch of science which answers the questions on natural phenomena ranging from the production of RNA and DNA and their collaboration within the nucleus and the cytoplasm of your cells to produce proteins to the exact timing of orbiting of the Earth around the Sun due to the gravitational attraction between the two which keeps us all alive.

Physics, as stated above, may seem to you as if related only to ‘Natural Sciences’. Then what about all the amazing creations of digital instruments such as your wrist watch or your calculator and the microprocessors that shrink the gigantic world into the size of a pin head? All these technical achievements are elaborate steps taken by the humans; more precisely; if you agree with me, by ‘Physicists’, emerging from the ordinary people like you and me.

All in all, physics is the fundamental study of natural phenomena based on force and energy, their interaction and the effective use of these abstract quantitative and qualitative aspects around us to bring about concrete, visible and reachable inventions to uplift the life standards of the human beings.
