# Modern Physics

Modern physics is a branch of physics in which matter and energy are not separate, but instead are alternate forms of one another. The term modern physics refers to the study of facts and theories developed in this century that concern the interactions of matter, space and time. There have been enormous advances in physics, and some of these advances have brought into question, or have directly contradicted, certain theories that had seemed to be strongly supported by the experimental evidence.

## What is Modern Physics?

Modern physics is a rich field including decisive experiments conducted in the early part of the twentieth century and most recent research that has given us a deeper understanding of fundamental process in nature. In conjunction with our growing understanding of the physical world, a burgeoning technology has led to the development of lasers, solid state devices, and many other innovations. This  section will give more idea about modern physics.

## Father of Modern Physics

Modern physics is a branch of physics existing after Newton. The classical physics was not enough to solve and explain the existing problems and hence modern physics came into existence. Einstein is called the father of modern physics. He was the one who came up with most of the concepts of modern physics. For example the theory of relativity was developed by him. Albert Einstein turned the scientific world on its head when he figured out E=mc2, the formula that said that energy and mass were actually the same thing i.e. the ability to do work and the material to do work with.
Einstein’s equation,

$E$ = $mc^{2}$

Einstein changed the way we think about space, time and matter. His contribution to theoretical physics was significant enough to award him with Nobel Prize. So he is rightly justified as the Father of Modern Physics.
