BSc Theoretical Physics
About this course
Theoretical physics addresses the deepest questions in natural science: what is matter made of at the most fundamental level, how does spacetime behave under extreme conditions, and what are the mathematical structures underlying the laws that govern the universe? Unlike experimental physics, which investigates nature through measurement and observation, theoretical physics constructs mathematical frameworks that explain and predict physical phenomena, from the quantum behaviour of subatomic particles to the large-scale structure of the cosmos. The discipline demands formidable mathematical ability alongside physical intuition, and it attracts students who want to understand how everything works at the most fundamental level. At Swansea University, this three-year full-time programme develops the analytical and mathematical skills needed to engage with the central ideas of theoretical physics, including classical mechanics, quantum mechanics, electromagnetism, statistical mechanics, and the theory of relativity. You will develop proficiency in the mathematical language that physics uses, from differential equations and linear algebra to group theory and complex analysis, using it as the primary tool for understanding physical systems. The programme explores how theoretical models are built, tested against experimental results, and extended to new regimes, developing the capacity for abstract reasoning and problem-solving that is the hallmark of a trained theoretical physicist. With a typical entry tariff of 104 UCAS points, this programme is accessible to students with strong mathematical and scientific aptitude who are committed to a rigorous analytical education. Graduates are well equipped for careers in physics research, scientific computing, financial mathematics, data science, quantitative analysis, engineering, and technology. The mathematical and problem-solving skills developed in theoretical physics are transferable to almost any quantitative field, and physics graduates are consistently among the most versatile in the job market. Many continue to postgraduate study in physics, mathematics, or related disciplines, and some pursue doctoral research.
