PHYS2055/PHYS1304 Introduction To Relativity

Topics include: "Common-sense" concepts of space and time versus Einstein's conceptions of space and time, examples of time dilation and space contraction, paradoxes of relativity including the famous twin paradox and the "pole-in-the-barn", four vectors and Lorentz invariant.

**Learning Outcomes**

On successful completion of this course, students should be able to:

- Recall the setup and significance of Michelson-Morley experiment.
- State the basic postulates and the spacetime concept of special relativity.
- Explain time dilation and length contraction.
- Describe Lorentz transformation and its applications.
- State the resolution of the twin and pole-in-the-barn paradoxes.

- The graded Assignment 1, 2, 3, Test and
