You’ll study a selection of mathematical techniques that are used for analysing physical behaviour. Topics will include:

• complex numbers
• calculus of a single variable
• plane geometry
• differential equations
• calculus of several variables
• matrix algebra

You’ll spend around three hours per week in workshops and lectures studying this module.

In this module you will receive: an introduction to the basic techniques and equipment used in experimental physics; training in the analysis and interpretation of experimental data; opportunities to observe phenomena discussed in theory modules and training in the skills of record keeping and writing scientific reports.

This year-long module will train you in the mathematical modelling of physical processes. You’ll cover topics such as basic statistics and errors, dimensional analysis, curve sketching, orders of magnitude and estimates, and integrating problems in physics among others. You’ll have an hour per week of lectures plus a number of 90-minute workshops throughout the year to assist in your learning.

You’ll receive training in basic computing techniques using MatLab, and will be introduced to their use in solving physical problems.

You’ll spend three to four hours in computer classes and a one hour lecture each week. 

This module introduces you to major areas of physics beyond those encountered in the core modules, including those at the forefront of modern research. Particular focus is placed on introductions to astronomy, biophysics and nanoscience. Other topics include condensed matter physics, atomic and particle physics and the physics of the environment.

You will develop your knowledge of the various physical processes occurring in stars of different types. You’ll use this knowledge to build both mathematical models and your qualitative physical understanding of stellar structure and evolution will be enhanced. You’ll have two hours per week of lectures studying this module.

In this module you’ll be introduced to the mathematical language for discussing extreme problems. The formulations of mechanics due to Lagrange and Hamilton will be described and techniques for the solutions of the consequent equations of motion will be discussed. You’ll learn the underlying principles of dynamics and develop techniques for the solution of dynamical problems. You’ll have two hours per week of lectures studying this module.

Macroscopic systems exhibit behaviour that is quite different from that of their microscopic constituents studied in isolation. New physics emerges from the interplay of many interacting degrees of freedom. In this module you will learn about the important physical properties of matter and the two main approaches to their description. One, thermodynamics, treats macroscopically relevant degrees of freedom (temperature, pressure and so on) and find relations between these and the fundamental laws which govern them, independent of their microscopic structure. The other approach, statistical mechanics, links the macroscopically relevant properties to the microphysics by replacing the detailed microscopic dynamics with a statistical description. The common feature of both of these methods is the introduction of two macroscopic quantities, temperature and entropy, that have no microscopic meaning.

Many physical systems support the propagation of waves, from the familiar waves on the surface of water to the electromagnetic waves that we perceive as light. The first half of the module will focus on optics: the study of light. Topics to be covered will include: geometrical optics; wave description of light; interference and diffraction; optical interferometry. The second half of the module will introduce more general methods for the discussion of wave propagation, and Fourier methods.

This module will develop your current understanding of the various physical processes that dictate the formation, evolution and structure of galaxies. You’ll explore a number of topics including The Milky Way, The Dynamics of Galaxies, Active Galaxies and Galaxy Evolution among others. You’ll spend two hours per week in lectures studying this module.

This module will provide an introduction to the theory and elementary applications of quantum mechanics, a theory that is one of the key achievements of 20th-century physics.

Quantum mechanics is an elegant theoretical construct that is both beautiful and mysterious. Some of the predictions of quantum mechanics are wholly counter-intuitive and there are aspects of it that are not properly understood but it has been tested experimentally for over 50 years and, wherever predictions can be made, they agree with experiment.

In the module From Newton to Einstein, you learnt about the idea of a field a quantity which is defined at every point in space. In this module, the description of fields will be extended by introducing the mathematics of vector calculus.

The module will begin with an introduction to vector calculus, illustrated in the context of the flow of ideal (non-viscous) fluids.

The math­ematics will then be used to provide a framework for describing, understanding and using the laws of electromagnetism. We discuss how electric and magnetic fields are related to each other and to electrical charges and electrical currents. The macroscopic description of electric fields inside dielectric materials and magnetic fields inside magnetizable materials will be described, including the boundary conditions that apply at material interfaces.

The last section of the module will discuss Maxwells equations of electrodynamics and how they lead to the vector wave equation for electromagnetic waves.

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. 

This module will introduce students to the physics of atoms, nuclei and the fundamental constituents of matter and their interactions. The module will also develop the quantum mechanical description of these.

You’ll carry out a project within the areas of chemical and molecular physics, which may be experimental or theoretical in nature.

Spending around two hours per week in lectures and tutorials, you’ll work in pairs to plan your project under the guidance of a project supervisor.

In this module you will develop your knowledge of classical mechanics of simple linear behaviour to include the behaviour of complex nonlinear dynamics. You’ll learn about the way in which nonlinear deterministic systems can exhibit essentially random behaviour because of sensitivity relating to initial conditions. You’ll have two hours per week of lectures studying this module.

You’ll extend and develop your  knowledge of quantum theory with a particular emphasis on how quantum systems evolve over time. The module will focus on developing the mathematical formalism of quantum mechanics as well as introducing important physical models and calculational techniques.

This module provides an introduction to the modern theory of gravitation: Einstein's general theory of relativity. This module is based on a regular series of two one-hour lectures per week supplemented by a two-hour workshop once a fortnight.

This module develops a range of modern astronomical techniques through student-centered approaches to topical research problems. You’ll cover a range of topics related to ongoing research in astronomy and astrophysics, and will encompass theoretical and observational approaches. This module is based on individual and group student-led activities involving the solution of topical problems including written reports and exercises, and a project.

This module introduces you to the key ideas behind modern approaches to our understanding of the role of inflation in the early and late universe, in particular through the formation of structure, the generation of anisotropies in the cosmic microwave background radiation, and the origin of dark energy. You’ll study through a series of staff lectures and student-led workshops.
