Theoretical Physics (TR035)

Theoretical Physics is a four year honours degree course combining modules in physics and mathematics. The programme emphasises the theoretical side of physics but includes experimental aspects. It also includes a range of modules in pure and applied mathematics and an introduction to computing. Topics include condensed matter physics, quantum mechanics, computational physics, particle physics, relativity, cosmology and astrophysics. All Trinity Physics degree courses are accredited by the Institute of Physics, which is the professional body for physicists in Ireland and the UK. Holders of accredited degrees can follow a route to Institute of Physics Membership and the 'Chartered Physicist' (CPhys). professional qualification.

What is Theoretical Physics?

Theoretical physics explores the natural world at its most fundamental level, using mathematical theories guided by experimental investigation. It can be the foundation for an academic career in mathematics or physics or the basis for a career in industry, medicine, law, finance or computing. Theoretical Physics graduates from Trinity are in high demand for their technical skills and versatility.

Theoretical Physics is taught jointly by the Schools of Physics and Mathematics and is an excellent course for those with good mathematical ability, who wish to acquire a deeper physical and mathematical knowledge of the world. In the first two years the course comprises 40 credits in Mathematics and 20 credits in Physics and includes both computational and experimental laboratory classes. In the third and fourth years students take 30 credits in Physics and 30 credits in specialist mathematics and Theoretical Physics modules in the School of Mathematics. Students also carry out a short computational Physics project in their final year.
