Postulates of Quantum Mechanics: Observables & Operators

The video tutorial introduces the concept of observables and operators in physics, particularly in quantum mechanics. It explains how classical physical parameters like momentum and energy are used differently at the quantum level, involving operators. The tutorial covers the Heisenberg uncertainty principle, the role of operators in determining possible values of observables, and how operators perform mathematical operations on functions. Examples include using operators to calculate expectation values and practical applications in chemistry.
