BSc Theoretical Physics
About this course
Theoretical physics addresses the deepest questions about the structure of the natural world through rigorous mathematical reasoning rather than primarily through experiment. Where experimental physics tests ideas against observation, theoretical physics develops the frameworks, models, and formalisms that give physical phenomena their most fundamental description. The great achievements of the discipline, including quantum mechanics, general relativity, and quantum field theory, have transformed our understanding of matter, energy, space, and time, and the questions that remain open are among the most challenging and profound that human beings have ever pursued. At Queen's University Belfast this three-year full-time programme provides a solid grounding in all aspects of physics while placing particular emphasis on its mathematical and theoretical dimensions. In your first two years you will study mechanics, applied mathematics, and computational physics alongside the core experimental and theoretical content of a physics degree. As you progress into your third year, a significant proportion of experimental laboratory work gives way to lecture courses and project work in theoretical topics, allowing you to engage more deeply with areas such as quantum theory, electromagnetic theory, and tensor field theory. The programme develops the mathematical fluency and physical intuition needed to construct and analyse theoretical models, and builds the computational skills that are increasingly central to theoretical research. Physics graduates, particularly those with strong mathematical and theoretical training, are among the most versatile in the academic and professional job market. Careers in research, both academic and industrial, are a natural destination, as are roles in data science, quantitative finance, software engineering, consultancy, and the technology sector, where the analytical rigor of theoretical physics is highly valued. Many graduates continue to postgraduate study in theoretical physics, applied mathematics, cosmology, or related fields, while others bring their problem-solving skills to careers in industries where complex quantitative reasoning is at a premium.
