TOPICS IN THEORETICAL PHYSICS - 2024/5

Module Overview

This 15-credit M-Level module introduces important topics and techniques in theoretical physics that have a wide range of applications in many areas physics and engineering and which the students will not have met before. Both the mathematical techniques and their applications are covered at a level appropriate for Masters level students coming to the end of their degree and who should be able to pull many different ideas in theoretical physics together.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate their understanding of mathematical techniques, their derivation (bookwork), their applications in physical examples, both of a type they have encountered in lectures and in the process of solving the examples in problem sheets and more original problems not encountered.

Thus, the summative assessment for this module consists of:

• A Coursework submission to be completed during the semester. 


• A written end of semester Examination (Final Unit of Assessment)), two hours long, in which the student must answer 3 from 4 questions covering all areas of the course.

Formative assessment and feedback

Regular feedback on previously taught material at the beginning of a lecture and discussion of problems and issues encountered in working through the problem sheets. These sheets will be discussed during the tutorial sessions. Model solutions to all problem sheet questions are made available after the students have had sufficient time to tackle them themselves. A revision class is set at the end of the module to go through past examination papers.

Module aims

• To provide a sound grounding two important topics mathematical physics: Complex Variable Theory and Calculus of Variations. In particular, the basic theorems, methods and applications of functions of a complex variable, a range of advanced integration techniques and theorems and their applications in a range of physical examples and variational principles in classical mechanics leading to both Lagrangian and Hamiltonian formulations.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to teach students the practical and problem solving skills required to tackle mathematical physics questions.  As such the teaching strategy places equal importance on lecture content and practical skills. For each topic covered in lectures there is an equivalent tutorial session, in which students will have further learning opportunities to develop their hands-on skills on the topics discussed in the lectures.

The learning and teaching methods include:

• lectures
• tutorial sessions
• hours of self-study

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.

Other information

The School of Mathematics and Physics is committed to developing graduates with strengths in Employability, Digital Capabilities, Global and Cultural Capabilities, Sustainability, and Resourcefulness and Resilience. This module is designed to allow students to develop knowledge, skills, and capabilities in the following areas:

Resourcefulness & resilience:

The mathematical content and methodology of the module forces students to develop problem solving skills in Physics and encourages critical thinking and reflection. Further to the more standard assessment in the form of a final year exam, students are also assessed on a coursework component, where they are given 3 to 4 topics to investigate on, with the aim to analyse them more in depth by performing some dedicated research. Students take up this extra challenge very well, and show a high degree of commitment, resourcefulness and resilience.

Employability:

By enhancing the mathematical and problem-solving skills of the students, the module offers large scope for increased employability. The general methodologies reviewed in the module will serve as a solid basis for making predictions in terms of theoretical modelling of different phenomena, not only in the physical sciences, but also in other disciplines. The coursework component of the module also offers scope for independent research work, to be compiled into a professional report, thereby helping student to enhance their written presentation skills.
