Mathematics and physics are closely interlinked subjects, with each providing many fascinating insights into the other. Students on this programme receive a thorough mathematical training and may also take modules in UCL Physics & Astronomy, as well as more widely across both UCL and the University of London. In the first year and a half of the BSc you will receive a thorough grounding in pure mathematics and mathematical methods following the same modules as the single-subject Mathematics students except that Quantum Mechanics can be taken in place of Algebra 3. The programme then follows relevant pure and applied mathematics options in the second half of the second year and in the third year, supplemented by physics modules given by UCL Physics & Astronomy.Possible options include: Atomic and Molecular Physics (UCL Physics & Astronomy) Mathematical Physics (King's College London) Quantum Mechanics (UCL Physics & Astronomy).
