Physics

Physics is the natural science. It studies matter, light, wave, electricity and their fundamental constituents, principles and behavior through space and time, energy and force. It is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.  

Now, physics is widens from macro level to quantum level. Fundamental concepts of modern physics are Causality, Covariance, Action, Physical field, Symmetry, Physical interaction, Statistical ensemble, Quantum, Wave and Particle.   Pure physics is now expanded and there is deep inter-disciplinary relation between physics and other natural science, i.e. chemistry, biology, mathematics, astronomy, space etc.

Physics is still attracting under graduate and graduate students as career and study discipline.
