This module shows how trends in chemical properties can be related to the structure of the Periodic Table and rationalise descriptive inorganic chemistry. 

To provide a fundamental understanding of the basics of organic chemistry, including nomenclature, molecular structure and bonding, stereochemistry and the chemical reactivity of common functional groups and reaction types through an understanding of their electronic properties. 

To provide an introduction to fundamental physical aspects of chemistry, which underpins all areas of Chemistry - emphasis will be placed on being able to apply knowledge, especially in solving problems. 

To introduce a range of chemical techniques appropriate to the study of inorganic, organic and physical chemistry at first year level, which will act as a foundation for more advanced work in subsequent years.

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

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 covers the mathematical background required for the majority of undergraduate-level study of physics and astronomy. It will complement the material studied in other first-year physics degree modules.

The structure of the module has been designed to ease students into the level of maths required for the early stages of your degree. 

The topics covered in this module are:

• Complex numbers
• Differentiation and Taylor Series representations
• Stationary points of two-dimensional functions
• Integration techniques for functions of single and multiple variables
• Partial derivatives of functions of multiple variables
• Conic sections in plane geometry
• Fourier representation of functions and the Fourier transform
• Matrices and eigenvalue problems

• Solving homogeneous and inhomogeneous linear constant coefficient ODEs

In this module you’ll look at green chemistry in its broadest sense, covering the fundamental concepts and chemistry involved in making chemical processes cleaner and more environmentally benign.

You’ll spend one hour per week in lectures, seminars and workshops over the whole year studying this module.

This module will introduce you to selected topics at the forefront of current research in chemistry from a physical chemistry perspective.

In this module you'll study  the physical principles underlying chemical phenomena, with emphasis on energy, quantum mechanics and spectroscopy. You'll also be introduced to solid-state chemistry, including the structure, characterisation, energetics and the band theory of solids.  

You’ll attend two hours of lectures each week in this module. 

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.

The notes, videos, and simulations for the first semester of The Quantum World are all publicly available and freely accessible. Check out the notes online, which include embedded links to the videos and interactive simulations.

You’ll study:

• Quantum vs classical states
• Fourier series and transforms: translating from position to momentum space
• The Heisenberg uncertainty principle (particularly from a Fourier perspective)
• The time-dependent and time-independent Schrödinger equation
• Bound and unbound states, scattering and tunnelling
• Wavepackets
• The subtleties of the particle in a box
• Operators, observables, and the thorny measurement problem
• Matrix mechanics and Dirac notation
• The quantum harmonic oscillator
• Conservation and correspondence principles
• Angular momentum
• Stern-Gerlach experiment
• Spin
• Zeeman effect, Rabi oscillations
• 2D and 3D systems
• Degeneracies
• Hydrogen atom and the radial Schrödinger equation
• Entanglement and non-locality
• ... and, of course, that ever-frustrating feline...

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:

• The fundamental principles and techniques of vector calculus, and methods to visualise and calculate the properties of scalar and vector fields
• The application of vector calculus to fluid flow problems
• Maxwell’s equations of electrodynamics, and their applications in electrostatics, magnetic fields and electromagnetic waves.

In this module students will receive:

• an introduction to the the basic techniques and equipment used in experimental physics
• training in the analysis and interpretation of experimental data
• a basic practical introduction to geometrical and physical optics
• opportunities to observe phenomena discussed in theory modules
• training in the skills of record keeping and writing scientific reports

You’ll be introduced to the principles of analytical chemistry, including the principal types of instrumentation used and the statistical treatment of analytical results.

You’ll attend two lectures each week studying this module.

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 covers material related to developing a more sustainable approach to chemistry. You will learn what constitutes sustainable chemistry, the significance of new technologies such as synthetic biology, and recognise the problems in achieving sustainability.
