Quantum mechanics is a fundamental physics subject that studies the phenomena at the atomic and subatomic scales. A general formalism of quantum mechanics can be elucidated based on several basic postulates. We choose to introduce the basic postulates of quantum mechanics via presenting the mathematical framework in which these postulates can be properly formulated. The physics interpretation of these postulates are only very briefly discussed. ...
