In the beginning all those who set their lives dedicated for acquisition of knowledge were called philosophers. Philosopher literally means “The lover of Knowledge”
The answers to the questions with “How” and “Why” led to the development of Physics as one of the wonderful subjects of all time. A Physicist is basically a problem solver. An expert in Physics is always found to be part of the solution. Wherever the Physics man is involved, either he solves the problem or offers a practical solution to the complex problems through logical reasoning and scientific method.
In the beginning Physics was basically Mechanics. But during the past few decades, Physics has grown to huge proportions and engulfed all fields through the applied side of the Physics principles.
