At UCD, Theoretical Physics puts emphasis on the mathematical description of physical phenomena, providing a unified picture of the fundamental laws of nature. It is ideally suited to students who enjoy studying Mathematics and Physics in secondary school. Insights from Theoretical Physics are driving our understanding of nature at all scales, from the origin of large-scale structures in the universe to the Planck scale, where our current understanding of space and time breaks down. The degree subject comprehensively covers Theoretical Physics, while developing your knowledge and expertise in problem solving, using analytical and computational techniques, which have wide application in, for example, biophysics, social physics, quantum physics, relativity and nanoscience.
