As our department name suggest, we do physics here for national development and of course for a living too. So what is physics to the ordinary man?
A good dictionary would define physics as the “study of matter, energy and the interaction between them” The word ‘Physics’ comes from the Greek ‘Knowledge of nature’ and in general, the field aims to analyze and understand the natural phenomena of the universe. It is sometimes referred to as natural science. Scientist of all disciples makes use of the ideas of physics, from chemists who study the structure of molecules to paleontologist who try to reconstruct how dinosaurs walked. It’s the foundation and superstructure of all engineering and technology of today. No engineer could design any kind of practical device without first understanding the basic principles of physics involve, To design a spaceship or a mouse trap, one has to understand the basic laws of physics.
