Mathematical Physics (MMath)

Mathematics is the fundamental language of physics. Physics uses maths to make predictions, and many mathematical areas have been developed to solve physical problems. This degree explores mathematical topics and how they appear throughout theoretical physics. You'll study particle physics, astrophysics and quantum field theory. You’ll graduate with technical skills sought by employers across science, industry and research.

This course is run by the School of Mathematical Sciences. It's taught jointly by Mathematical Sciences and Physics and Astronomy, through the STAG (Southampton, Theory, Astronomy and Gravitation) research centre. STAG is a leader in the latest research in theoretical particle physics, astronomy, general relativity and string theory.

The mathematical part of this course begins with the fundamental areas of calculus, linear algebra, vector calculus and partial differential equations.

The physics part includes the key ideas of relativity, cosmology and astrophysics, applications of laser technology, atomic and particle physics, and optoelectronics.

As part of this course you’ll:

• Identify the key areas of physics theory relevant to a given problem

• Construct mathematical models for physical situations

• Choose to specialise in areas such as particle physics, astrophysics or condensed matter

• Use our student centre, a dedicated learning and social space, exclusively for maths students

• Use mathematical and computational packages such as Python and the statistics package 'R'

The programme will take you to the frontier of knowledge in this exciting field, allowing you to study as an undergraduate, material that would normally be taught at MSc level.

Southampton mathematics graduates are in great demand. Many employers look for graduates with strong problem-solving skills who can develop sound analytical arguments. Depending on your degree specialism, a wide range of career destinations are available including mathematician, statistician, actuary and financial analyst. Our graduates are employed by organisations including Deloitte, British Airways, IBM, Amazon UK and Formula 1 racing teams and earn on average £36,700 with over 97% in employment or further study within 15 months of graduating (Graduate Outcomes 2022-23, published 2025).
