Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum mechanics to the entire universe using general relativity. Physical science is one of the oldest academic disciplines which over time have converged with several other scientific disciplines to form new branches viz. biophysics, robotics, astrophysics, etc. Modern physics intends to imply the classical physics? concepts towards the development of new and advanced methods and tools that can find practical applications in health, telecommunication and electronics industry.
