                     Unit 10 – Special Theory of Relativity
1.   Newtonian    mechanics,      Kinetic        theory   and   Maxwell’s   theory   of
     electromagnetism were the product of classical physics. They were very
     successful in explaining a wide range of natural phenomena. Newtonian
     mechanics beautifully explained the motion of objects on Earth and in the
     heavens. Furthermore, it formed the basis for successful treatment of fluids,
     wave motion and sound. Kinetic theory explained the behavior of gases and
     other materials. Maxwell’s theory of electromagnetism not only brought
     together and explained electric and magnetic phenomena, but it predicted
     the existence of electromagnetic (EM) waves that would behave in every
     way just like light – so light came to be thought of as an electromagnetic
     wave. Indeed, it seemed that the natural world, as seen through the eyes of
     physics, was very well explained with the exceptions of a few puzzles.
        The theory of relativity and the quantum theory were introduced by
     modern physics.
2. The special theory of relativity and the quantum theory are the two theories
     underlying the tremendous progress of physics during the last hundred
     years. Albert Einstein’s general relativity provides a theoretical framework
     for understanding the universe on the largest of scales: stars, galaxies,
     clusters of galaxies, and beyond to the immense expanse of the universe
     itself. The other is quantum mechanics, which provides a theoretical
     framework for understanding the universe on the smallest of scales:
     molecules, atoms and all the way down to subatomic like electrons and
     quarks. Through years of research, physicists have experimentally
     confirmed to almost unmanageable accuracy virtually all predictions made
     by each of these theories.
