What does perturbation mean?
1 : the action of perturbing : the state of being perturbed. 2 : a disturbance of motion, course, arrangement, or state of equilibrium especially : a disturbance of the regular and usually elliptical course of motion of a celestial body that is produced by some force additional to that which causes its regular motion.

Who invented perturbation theory?
Paul Dirac
These well-developed perturbation methods were adopted and adapted to solve new problems arising during the development of quantum mechanics in 20th century atomic and subatomic physics. Paul Dirac developed quantum perturbation theory in 1927 to evaluate when a particle would be emitted in radioactive elements.
What is perturbation theory and why we use this theory?
Perturbation theory is a method for continuously improving a previously obtained approximate solution to a problem, and it is an important and general method for finding approximate solutions to the Schrödinger equation. We discussed a simple application of the perturbation technique previously with the Zeeman effect.
What is the purpose of perturbation theory?
There is a general method of calculating these errors; it is called perturbation theory. One of the most important applications of perturbation theory is to calculate the probability of a transition between states of a continuous spectrum under the action of a constant (time-independent) perturbation.
Is Discompose a word?

What is the principle of perturbation theory?
The principle of perturbation theory is to study dynamical systems that are small perturbations of `simple’ systems. Here simple may refer to `linear’ or `integrable’ or `normal form truncation’, etc. In many cases general `dissipative’ systems can be viewed as small perturbations of Hamiltonian systems.
