What is Quantum Mechanics?
Quantum mechanics is a tool or theory in physics that is used to describe the state of the world or a system at the subatomic level. The theory depends on states of the system, observables, measurements and evolution evolution of the system. These are used in building a mathematical model to study quantum mechanics.
In classical mechanics, Newton's laws are used to study physical systems whose behaviour are visible to the human eye. These laws do not apply to systems with quantum effect (this is an effect that cannot be described by classical physics) such as quantum entanglement, radioactive decay and wave particle duality. Such systems are called quantum systems (examples are atoms, molecules, particle on a pendulum etc). Schroedinger equation is one of the tools used in describing such systems.
Schroedinger equation is an equation that describes a systems that has significant of quantum effect. It is a partial differential equation whose solution is a wave function . This is used to study the evolution of the system as time goes by.
