How does the world really work?

We’ll take you from Newton’s mechanics, the pinnacle of the scientific revolution and the foundation of our understanding of modern physics, right through to our current understanding of physics with Einstein’s theory of relativity and quantum mechanics.

This module will underpin your entire physics degree. It contains all the ideas and principles that form the basis of our modern world. As you’ll find out, some of these ideas are very strange indeed.

You’ll study:

• Newton’s laws of mechanics
• The physics of waves and oscillations
• Electricity and magnetism
• Quantum mechanics and the foundations of modern physics
• Einstein’s relativity

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 module will cover major areas at the forefront of modern research, beyond those encountered in the core modules. You’ll be introduced to cutting-edge topics in medical physics, nanoscience, and astronomy by experts in each of these fields.

The frontiers of knowledge in physics are constantly changing. This module will cover major areas at the forefront of modern research, beyond those encountered in the core modules. You’ll be introduced to cutting-edge topics in medical physics, nanoscience, and astronomy by experts in each of these fields.

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

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

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

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.

In this module you will learn how the same physics that works on Earth – gravity, electromagnetism, thermodynamics, optics, quantum physics, atomic and nuclear physics – is used to understand stars. You will explore the most important physical processes occurring in stars of different types. You will then use this knowledge to build mathematical models of stars and to understand their internal structure, their formation, evolution, and death.

You’ll study:

• How astronomers measure the most important properties of stars such as their mass, size, distance, brightness, temperature, chemical composition and age. This module will then teach you how physics is able to explain these properties.

• Macroscopic characterisation of matter, for example how liquid nitrogen is made and understood
• Statistical formulation, linking micro and macro systems
• Quantum statistics, providing a theory for everything!

In this module you will explore the concepts of scalar and vector fields. You will learn the mathematics of vector calculus, which give us a powerful tool for studying the properties of fields and understanding their physics.

You will then study its application in two important and contrasting areas of physics: fluid dynamics, and electromagnetism. We use examples such as water draining from a sink or wind in a tornado to provide intuitive illustrations of the application of vector calculus, which can then help us to understand the behaviour of electric and magnetic fields.

You’ll study:

This module will develop your current understanding of the various large-scale physical processes that dictate the formation, evolution and structure of galaxies, from when the Universe was in its infancy to the present day.

You’ll explore a range of topics, starting with the fundamentals of observational techniques used by astronomers for understanding the structure of our own galaxy, the Milky Way. We will then look at the more sophisticated ways of unpicking the physics that drives the complexity we see throughout the population of galaxies in the Universe.

Specifically, in this module, you will study:

This module provides an introduction to the theory and elementary applications of quantum mechanics, a theory that is one of the key achievements of 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. Nonetheless, it has been thoroughly tested empirically for nearly a century and, wherever predictions can be made, they agree with experiment.

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.

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?

This module will introduce you to the mathematical language behind the classical mechanics describing our universe.

Electronic devices such as transistors and light emitting diodes are the basic building blocks of the technology that underpins all aspects of the modern world.

Previous modules on Solid State Physics and Semiconductor Physics should have given you a good understanding of how these devices work. The move to make these building blocks ever smaller leads us into regimes where we have to treat the quantum nature of electrons in solids much more seriously.
