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 study:

• Medical physics: the physics of sound and hearing; radioactivity in medicine; magnetic resonance imaging

The physics of waves features in our everyday lives. Waves are important phenomena. They include:

• electromagnetic waves that we know as light
• communication via radio and microwaves
• surface waves on water
• shock waves in earthquakes

Understanding light and how it can be manipulated leads to important technical applications such as optics and cameras in mobile phones, telecommunication and the internet or even quantum computers.

This module will cover the wave description of light; geometrical optics and imaging, 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.

You’ll study:

In this module we will learn how physicists can harness the health benefits of using radiation, as well as measuring and controlling levels of radiation in the environment or therapy.

Radiation is a term which can cover many different phenomena and a wide range of energies (acoustic, electromagnetic, ionizing). It can come from a wide range of sources (natural or manufactured). In the public eye radiation can often be seen as a danger e.g. location of mobile phone masts.

This module explores how physics-based techniques are used to gain insight into complex molecular systems of biological relevance. In studying the physics underpinning this area of research where chemistry, biology and physics all overlap, we will draw on principles derived from quantum mechanics and statistical physics to develop a better understanding of the biomolecular world.

Physics has made significant contributions in our efforts to understand the underlying molecular principles of life. For instance, physics plays an important role in the development of sophisticated methods that make it possible to measure the complex structure of biological molecules and their mutual interactions and dynamics. Two important groups of such biomolecules that will be discussed in the module are proteins and deoxynucleic acids (DNA).

• How can molecular forces and distances be measured between individual molecules.

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. 

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.

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.

This module explores the physical processes involved in the most extreme environments known in the Universe. Among the objects studied are neutron stars, black holes, supernova explosions, and active galactic nuclei.

The invention of the scanning tunneling microscope (STM) in the 1980s has led to a revolution in the imaging of surfaces and has provided an enormous stimulus for the development of nanoscience. The operation of a scanning probe microscope relies on the interaction between a local probe and a surface. A family of techniques has been derived from the STM which exploit a range of different forces and other interactions for image formation. The most widely-used of these techniques is atomic force microscopy which, unlike, STM, can be used to image insulating samples. In this module the focus will be on the development of physical models to describe the interaction between a local point-like probe and a surface. The operation of the STM will be considered in detail together with design considerations which are common across all scanning probe microscopes. In the second half of the course, forces between the tip and sample will be considered and methods for measuring these interactions will be discussed. The probe-surface interaction can also be used to modify the surface with a specificity which can result in placement of single atoms and molecules and these patterning processes will be discussed. Throughout the course images from the current research literature will be introduced to inform students of the range of possible applications of this these techniques.

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.
• How energy is generated inside stars through nuclear fusion, and how it is transported to the surface to make stars shine.
• How to write the equations that describe the structure of stars, and how to use them to build mathematical models that explain their properties and evolution.
• How stars are born, how they evolve with time, how long they live, how they die, and what remnants they leave behind. You will be able to understand, for instance, how supernovae explode and how some black holes form.

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.

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.

• 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.
