# SPECIAL RELATIVITY - 2021/2

Module code: PHY3038

## Module Overview

An FHEQ Level 6 course on Einstein’s theory of Special Relativity in a rigorous four vector and tensor approach. Postulates and principles are reviewed. The course then develops relativistic dynamics of point-particles and waves and the relativistic treatment of electromagnetic and electrodynamics phenomena

## Assessment Strategy

The __assessment strategy__ is designed to provide students with the opportunity to demonstrate

understanding of the concepts of Special Relativity; the ability to apply these concepts to problems in the physics of particle and wave mechanics; an understanding of the links between Special Relativity and Electromagnetism; the ability to tackle problems linking these two areas.

Thus, the__summative assessment__for this module consists of:

• Coursework; a written report on a conceptual aspect of Special Relativity; 30%, 1000 words (addresses learning outcome 4)

• 2.0 hour examination at the end of the semester (70%), with a section A of compulsory questions and a section B with 2 questions chosen from 3. In Part A answer all questions (20 points); In Part B answer two questions out of three (20-points each). If all three questions in Part B are attempted only the best two will be counted. (addresses learning outcomes 1, 2, 3, and 4)

__Formative assessment__

Problem sets are issued during the course, and some of the class time (1h in even weeks) will be devoted to problem-solving tutorials.

__Feedback__

Students will receive detailed feedback on the coursework assignment; oral feedback is given in tutorial sessions on the problem sets. One problem set will be marked and returned as a kind of mock exam paper.

## Module aims

- develop the theory and conceptual understanding of special relativity and space-time from first principles, using four-vector and tensor notations, providing applications of the theory from the dynamics of point particles through to electrodynamic phenomena.

## Learning outcomes

## Methods of Teaching / Learning

The __learning and teaching__ strategy is designed to:

Enable students to understand the physics concepts involved in Special Relativity, how they interlink with Electromagnetism, and to equip students with the formal methods necessary to enable them to tackle a wide range of applications and problems in Special Relativity and guide further study.

The __learning and teaching__ methods include:

3 hours of lectures/tutorials per week x 11 weeks. Problem sets will be issued throughout the course to give practice at problem-solving.

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
