# MTH480: Introductory Quantum Mechanics

## Objective

The physical principles and mathematical formalism of quantum theory, with emphasis on applications to atomic, molecular, and many-body physics; scattering phenomena; and electromagnetism (photon physics).

It is intended to supplement the discussion of hydrogen and many-electron orbitalâ€™s commonly found in general chemistry text books with a deeper understanding of the underlying physical principles. The relationship between classical and quantum mechanics is explored to illustrate how physical objects can be viewed both as a particle and a wave.
