You will carry out a project drawn from one of several areas of physics. The project may be experimental or theoretical in nature. Many of the projects reflect the research interests of members of academic staff. You will work in pairs and are expected to produce a plan of work and to identify realistic goals for your project. Each pair has a project supervisor responsible for setting the project. You will also be required to maintain a diary/laboratory notebook throughout.
Occasionally the work from these projects is used in scientific publications, and the students involved are named as authors on those publications.
Depending upon the type of project that you decide to do, you will design and carry out your own experiments, theoretical calculations or computational work and use them to generate what are often new and interesting results. The project culminates in your writing a scientific report which is submitted for assessment along with your laboratory notebook.
Introduction to Solid State Physics
Solid state physics underpins almost every technological development around us, from solar cells and LEDs to silicon chips and mobile phones.
The aim of this module is to introduce to you the fundamental topics in solid state physics. We start by looking at why atoms and molecules come together to form a crystal structure. We then follow the electronic structure of these through to interesting electronic, thermal and magnetic properties that we can harness to make devices.

Principles of Dynamics
This module will introduce you to the mathematical language behind the classical mechanics describing our universe. You will learn about Lagrangians and Hamiltonians, the starting place from which we can determine the dynamics of complicated systems, like pendula and planets orbiting the sun, as well as the origin of conserved quantities such as energy and momentum.
This is a fun module. At school you learnt Kepler’s Laws, Newton’s Law of Gravity, and F=ma, but how can you derive these amazing results? Where do they come from?
Here you will find out, as we introduce you to the mathematical language behind the classical mechanics describing our universe. You will learn about Lagrangians and Hamiltonians, the starting place from which we can determine the dynamics of complicated systems, like pendula and planets orbiting the sun, as well as the origin of conserved quantities such as energy and momentum. For two hours a week we will take you into the mathematics and ideas of giants like Newton, Euler, Lagrange, Noether and Hamilton.
Among many exciting things, you will study:
- Newton’s Laws and deriving the orbits predicted by Kepler
- Lagrangians and Hamiltonians, the building blocks behind classical mechanics
- The Euler-Lagrange equations describing the dynamics behind classical systems
- Rigid bodies – introducing moments of inertia, centre of mass and more so that we can apply these results to many particle rigid systems, like pendulums and even you
- Constraints – how to determine the dynamics of a system where it is constrained, for example, the motion of an explorer constrained to be on the surface of the earth
- The motion of charged particles, like electrons in an electromagnetic field
- Hamilton’s equations as an alternative way to determine the dynamics of a system, particularly useful when we are searching for conserved quantities like angular momentum
- Spinning tops – what? You heard right, the vital roles of gyroscopes in our life are understood by 5-year-olds, but the mathematics certainly is not. Thanks to this course, now you can understand that as well.
This module aims to provide you with the skills necessary to use computational methods in the solution of non-trivial problems in physics and astronomy. You’ll also sharpen your programming skills through a three hour computing class and one hour of lectures per week.
From Accelerators to Medical Imaging
Science is the cornerstone of modern healthcare. For example, in the UK’s National Health Service (NHS) more than 80% of clinical decisions are informed by scientific analysis.
In this module, we will explore some of the critical technologies that underpin these decisions. The course begins by exploring particle accelerators, and how they are used to create, for example, high energy photons or anti-matter particles. We will then see how these are used to either diagnose or treat illnesses such as cancer.
We will look closely at medical imaging techniques such as X-ray computed tomography (the CT scan), exploring the mathematics of how high-definition images of the body can be formed. We will cover nuclear medicine – how radiation can be used to track the function of organs in the body – and how advanced mathematical models feed into diagnostic decisions.
Understanding the dynamics of quantum systems is crucial, not just for describing the fundamental physics of atoms, but also for the development of exciting new quantum-based technologies. This module will equip you with the key theoretical concepts and methods needed to explore how quantum systems evolve with time.
- Connections between the dynamics of quantum systems and that of more familiar classical ones
- When (and how) to use approximations that allow complex problems to be made much simpler

Enterprise for Chemists
Students will learn about the factors that lead to successful innovation, including evaluation and management of an idea/concept.
In addition, students will consider the factors required to extract the value from a product/concept (e.g. market awareness) and the potential routes to market available from both an academic and industrial viewpoint.
Functional Medical Imaging
The techniques for magnetic resonance imaging (MRI) and spectroscopy (MRS) are explored. The course aims to introduce the brain imaging technique of functional magnetic resonance imaging (fMRI), giving an overview of the physics involved in this technique. The electromagnetic techniques of electroencephalography (EEG) and magnetoencephalography (MEG) will then be outlined, and the relative advantages of the techniques described.
Symmetry and Action Principles in Physics
Symmetry plays a central role in physics. Most of the fundamental Laws of modern physics have been formulated using symmetry principles. Symmetry is also expected to guide for further understanding and development of theories of physical phenomena.
Through a combination of lectures, engagement sessions and workshops, this module equips you with:
- the key concepts of symmetry
- the correspondence between symmetries and conservation laws
- the derivations of physics laws from the action principles
- and the consequences of symmetry breaking.
- Symmetries of space and phase space using classical mechanics
- Symmetries of spacetime and in electromagnetism using special relativity
- Main symmetry groups of modern physics laws
- How structures in nature are results of symmetry breaking.
Force and Function at the Nanoscale
We will study some of the fundamental forces at the nanoscale and look at the role of key concepts such as entropy. We will also learn how we can visualise and measure the nanoscale structures that form.
The nanoscale world is very different from our regular experience. Thermal energy pushes and pulls everything towards a state of disorder whilst nanoscale forces allow for materials to resist this and stay together. We will study some of the fundamental forces at the nanoscale and look at the role of key concepts such as entropy. We will also learn how we can visualise and measure the nanoscale structures that form.
While the forces we will study operate over distances as small as 1 nanometre we will explore how these concepts are responsible for phenomena in our everyday world we often don’t even think about:
- Why is a droplet spherical?
- What is going on when you scramble an egg?
- How can a gecko walk across a perfectly smooth ceiling?
- Why do you use soap when you wash?
- Why don’t oil and water mix?
