What is modern physics?
Modern physics is a branch of physics which deals with the post-Newtonian concepts in world of physics. It is based on the two major breakthroughs of twentieth century: Relativity and Quantum Mechanics.
Modern physics often involves advance description of nature through new theories which were different from the classical descriptions and involves elements of quantum mechanics and Einsteinian relativity. For instance, quantum effects typically involves distances related to atoms. On the other hand, relativistic effects typically involve velocities compared to the speed of light.
Albert Einstein is known as the father of modern physics. He was a 20th century scientist, who came up with most important ideas. One of the important work of Albert Einstein is the theory of relativity and the famous equation E=mc2.
He was awarded the Nobel Prize for physics in 1921 for his achievements in theoretical physics, particularly discovering the laws of photoelectric effect
