This course, Quantum Mechanics I, introduces the fundamental principles governing the behavior of matter at the atomic and subatomic levels. It begins with a review of essential mathematical concepts, including vector spaces and operators. The course explores the inadequacies of classical mechanics, leading to the introduction of the Schroedinger equation and postulates of quantum mechanics. Students will learn to solve time-independent Schroedinger equations for various potentials, including infinite and finite potential wells, and the harmonic oscillator.
