Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. Physics helps us to understand how the world around us works, from can openers, light bulbs and cell phones to muscles, lungs and brains; from paints, piccolos and pirouettes to cameras, cars and cathedrals; from earthquakes, tsunamis and hurricanes to quarks, DNA and black holes.

The main objectives are:

• To understand the functional role of nature and explain it in a complete form.

• To provide knowledge of the laws of nature after verifying them by experiments.

• To control nature by the applications of results of experiments performed through keen observation.
