# Modern Physics

Every physical system can be characterized by its size and length of time it taken for processes occurring within it to evolve. This is as true of the electrons circulating about the nucleus of an atom as it is of a chain of mountains rising up over the ages.

## What is Modern Physics?

Back to Top
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

Back to Top
Modern physics is basically the concepts 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. Speed of light is considered here. Albert 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 given by him. He also formulated the Einstein’s equation,

$E$ = $mc^{2}$

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.

## Particle Physics

Back to Top
This branch of science basically deals with the particles that make up matter. The interaction between these particles and their existence is studied in particle physics. The standard model is the latest model that describes the existence of particles that make up matter any some fundamental interaction amongst them. These are the strong, weak as well as electromagnetic interactions. It states the existence of 24 fundamental particles. It also predicts the existence of Higgs Boson. Particle physics’ aim is to develop fundamental models, conduct experiments etc. for the discovery of new fundamental particles that make up matter.
The main future aim is to develop and research beyond the “standard model” so that further revolutions can be made. There are Collider and non Collider experiments for the same.

## Nuclear Physics

Back to Top
The branch of science that deals with the fundamental particle namely nucleus is called Nuclear Physics. Nuclear physics basically deals with the structure and components of nucleus. The properties like radius mass etc are dealt with and studied. Various models related to the nucleus and their development by various scientists,their experiments, theories etc. are the part of Nuclear Physics.
