Welcome to the School of Physics
The search for a fundamental understanding and the drive towards technological development in areas such as computer hardware continue to pose fresh challenges to physicists. They are tackled with a combination of experiment, theory and computation. Our undergraduate degree courses combine all three of these elements, and prepare the student for a wide range of careers.

Tercentenary of Physics in Trinity
The Erasmus’ Smith Professorship of Natural and Experimental Philosophy was established in 1724 and marked the beginning of the formal teaching of the subject we now call Physics in Trinity College Dublin. There has been enormous growth and transformation in the School of Physics over the past three centuries. We are organising a series of events to celebrate the occasion, honouring the scientific achievements of past and current physicists, as well as the highlighting the importance of physics to the national technology landscape and economic prosperity.
