To provide a broad understanding of string theory, and its utilization as a theory that unifies all of the known fundamental matter and interactions.

After completing the module the students should:

- be familiar with the properties of the classical string.
- be familiar with the basic structure of modern particle physics and how it may arise from string theory.
- be familiar with the basic properties of first quantized string and the implications for space-time dimensions.

- be familiar with string toroidal compactifications and T-duality.
