Who Is the Father of Modern Physics?
Albert Einstein is known as the father of modern physics. He was a 20th-century scientist, who came up with the most important ideas. One of the important works 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…

What Is Modern Physics?
Modern physics is a branch of physics that deals with the post-Newtonian concepts in the world of physics. It is based on the two major breakthroughs of the twentieth century: Relativity and Quantum Mechanics.Quantum effects typically involve distances related to atoms. On the other hand, relativistic effects typically involve velocities compared to the speed of light.
