Physics is crucial to understanding the world around us, the world inside us, and the world beyond us. It challenges our imaginations with concepts like relativity and quantum mechanics, and has provided the foundations for many new technologies that have changed our lives: mobile phones, the internet, and MRIs are only a few examples of the physics-based technological developments that have revolutionized our world. Many physicists work as engineers, bringing with them unique insights and perspectives resulting from their training in physics.

Accredited degree courses on offer in the School of Physics encompass the study of the universe from the largest galaxies to the smallest subatomic particles and include topics ranging from the atmosphere and environment to medical physics. However, the importance of physics isn't limited to the "hard sciences". Increasingly, physicists are turning their talents to diverse fields such as molecular biology, archaeology, medicine, the arts and even the world of finance. In Galway, we have a strong tradition of providing "hands-on" degrees in Physics and our graduates are much in demand - you don't need to take our word for it: click here to meet the graduates!

Teaching in the School of Physics is strongly influenced by programs of advanced research and graduate education. These programs are based on our research clusters: Applied Optics & Laser Applications; Atmospheric and Environmental Physics; and the Centre for Astronomy. Access to the expertise and facilities of these clusters can be made available to industrial partners.

So physics is interesting, relevant, and it can prepare you for great jobs in a wide variety of places. Why not pursue a physics degree with us here in NUI, Galway and let us share our knowledge and enthusiasm with you? You can join this fascinating journey at any point in your career, please explore further by clicking on any of the options above
