QUANTUM MECHANICS

 BASIC TERMINOLOGY  Quantum:- It is the smallest entity which is required to define the properties of existence of anything.      Physics:- It is a natural science that studies about matter,its motion  and behavior through space and time, and the related entities of energy and force.     Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.   Mechanics:- Mechanics is the branch of Physics dealing with the study of motion when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. There are two sub disciplines Classical Fields and Quantum Fields    Classical Mechanics:-  Classical mechanics deals with the question of how an object moves when it is subjected to various forces, and also with the question of what forces act on an object which is not moving. The word “classical” indicates that we are not discussing situations in which an object moves with a velocity
