Quantum mechanics is a fundamental branch of theoretical physics that replaces Newtonian mechanics and classical electromagnetism at the atomic and subatomic levels.
It is the underlying framework of many fields of physics and chemistry, including condensed matter physics, quantum chemistry, and particle physics.
Along with general relativity, it is one of the pillars of modern physics.
