Physics is a branch of natural sciences that can boast of having the greatest, strongest and beyond imagination contribution to the development of scientific temper and new kind of philosophy to unravel the mysteries of life and cosmos that has always been a prime focus of interest by past as well as present civilization on Earth. Since it is a book about a very brief introduction to the basic postulates and principles of physics leading to the latest cutting edge scientific and technical developments, so it is not very much exhaustive. The aim here is not to explain each and every concept of physics but to systematically correlate some crucial aspects to provide a glimpse of what can be achieved using the power of physics.
