Quantum mechanics is a physical science dealing with the behaviour of matter and energy on the scale of atoms and subatomic particles or waves. The term "quantum mechanics" was first coined by Max Born in 1924.
That theory is known as quantum mechanics, and it is now the basic framework for understanding atomic, nuclear, and subnuclear physics, as well as condensed-matter (or ”solid-state”) physics.

tried to explain how classical mechanics emerges from quantum mechanics. Classical mechanics is about movement and change, while the strong empha-sis on stationary states in traditional quantum courses makes the quantum world seem static and irreconcilably different from the world of every-day experience and intuition.
Derive the Heisenberg equations of motion for the creation and annihilation operators in the simple harmonic oscillator and show that their solution is. a(t) = a(0)e i!t ; ay(t) = ay(0)ei!t : (370) From these, obtain equations of motion for the position and momentum operators.
