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.
