BSc Physics with Theoretical Physics
About this course
Physics with Theoretical Physics is a degree for those who want to understand the deepest principles governing the natural world. Where experimental physics engages closely with what can be measured and tested in the laboratory, theoretical physics works at the level of mathematical frameworks: constructing and refining the models that explain phenomena from the behaviour of subatomic particles to the large-scale structure of the cosmos. The two approaches are inseparable in practice, and together they define one of humanity's most sustained and successful intellectual projects. At Imperial College London, this three-year full-time degree is taught within one of the world's leading physics departments. You will cover classical and quantum mechanics, electromagnetism, thermodynamics, and special and general relativity, building a comprehensive foundation in the fundamental laws of nature. The theoretical strand deepens this with a stronger emphasis on the mathematical structures that underlie physical laws, including quantum field theory and the methods used to model systems that cannot be solved exactly. Problems in physics span phenomena on gigantic scales, such as the evolution of the cosmos, and minutely small ones, such as the interactions of quarks and leptons, and the theoretical physicist's task is to find the frameworks that describe them all with consistency and precision. You will develop exceptional problem-solving ability, deep mathematical fluency, and the capacity to reason carefully about complex systems under uncertainty. These skills are among the most transferable in any scientific training, and physics graduates from institutions like Imperial are recognised as such by employers across a wide range of sectors. Graduates from physics with theoretical physics programmes pursue careers in academic research, finance and quantitative analysis, engineering, data science, technology development, and scientific computing. Doctoral study is a common route for those who wish to remain in academic or industrial research. The rigour and depth of a degree from Imperial opens doors well beyond physics itself, and many graduates find their careers take them into fields where analytical thinking and mathematical modelling are valued most highly.
