Learning Outcomes

On successful completion of this module students should be able to:

1. Outline the basic features of quantum mechanics.
2. Define basic notions from quantum theory and recognise their occurrence and relevance in applied problems.
3. Demonstrate the ability to perform simple computations relevant to introductory quantum theory and solve specific problems from quantum physics formulated in the appropriate theoretical terms.
4. Demonstrate an understanding of the basic principles of special relativity.
5. Produce special relativity parameters in graphical format and in mathematical notation.
6. Solve simple problems in special relativity.

Aims

Quantum mechanics underpins a significant proportion of theory in physics. This first-year module provides an introduction to the field. The module also provides an introduction to the theory of special relativity. These introductions prepare student for use of both topics in the more advance modules of Part 2.

Brief description

Quantum theory is essential to describe the interaction between matter and radiation at the atomic scale. It is however a radical departure from classical physics. This module will introduce the key areas in which classical and quantum mechanics differ, examine the experimental evidence, and develop the core principles of quantum mechanics. Special relativity is another field which departs from the classical approach of Newtonian mechanics. The concepts and basic equations of special relativity are introduced through discussions of key experiments.
