MPhys Theoretical Physics
About this course
Theoretical physics is physics pursued at its most mathematically rigorous and conceptually ambitious. Where experimental physics tests theories against measurement, theoretical physics constructs and explores the mathematical frameworks that describe the fundamental laws of nature, from quantum mechanics and quantum field theory to general relativity, string theory, and the statistical mechanics of complex systems. It is one of the most intellectually demanding disciplines in all of science, requiring command of advanced mathematics alongside a deep physical intuition about how the universe works, and it is a degree that genuinely tests the limits of what is known. At the University of Durham, this four-year full-time programme is one of the most well-regarded theoretical physics degrees in the UK. Durham has exceptional research strength in theoretical physics, particularly in cosmology, quantum field theory, string theory, and soft matter physics, and students studying here are working within a department that pushes at the frontiers of the discipline. You will study classical mechanics, electromagnetism, and special relativity in the early stages of the degree before progressing to quantum mechanics, statistical mechanics, quantum field theory, and general relativity, with optional specialisation in areas of theoretical physics research where the department is particularly strong. The mathematical training is exceptionally rigorous. You will develop fluency with differential equations, complex analysis, linear algebra, group theory, differential geometry, and many other areas of mathematics as tools for theoretical physics, and this level of mathematical sophistication is precisely what distinguishes the graduate profile of theoretical physicists and makes them sought after far beyond academia. Many theoretical physics graduates pursue academic research, either in physics or in mathematical sciences, through postgraduate study at masters or doctoral level. Others move into the financial sector, where quantitative skills of the highest order are valued in derivatives pricing, risk management, and quantitative trading. Data science, software engineering, and technology companies also recruit theoretical physicists. The intellectual formation that this degree provides opens doors across the full spectrum of quantitative careers.
