What is Physics?

Physics is the study of the natural or material world and natural phenomena around us, including the fundamental particles of nature and their interactions, properties of atomic nuclei, atoms, molecules, gases and solid matter. It covers fields such as astrophysics, cosmology, and physics of materials. The laws of physics are the laws which govern electricity and magnetism in modern devices such as mobile phones, computers, the internet, radio and television broadcasts, the mechanics of aviation and space flight, quantum mechanics underlying magnetic resonance imaging in medicine etc.

Is this the right course for you?

If you like doing experiments and working in the lab, if you are interested in how the universe began and evolved, or if you enjoy physics, technology, computing, maths and solving problems then you should consider studying Physics or Physics and Astrophysics.

Why study Physics at Trinity?

Physics at Trinity enjoys a worldwide reputation, and provides an exceptionally stimulating environment for study and for subsequent postgraduate work. This course offers you the opportunity to study with world-leading experts in the School of Physics, with modules designed to provide you with a flexible qualification for employment across a range of research and industrial settings.

What will you study?

Students follow the Science (TR071) course in their first two-years and must take the prescribed modules in Physics and Mathematics in both years, which will include Introductory Astrophysics, Thermodynamics, Electricity, Sound and Optics, Nuclear Physics and Quantum Physics. Students spend three hours per week in the experimental or computer laboratories.

In Junior Sophister (third) year, Physics and Physics and Astrophysics students spend one day per week in the experimental laboratory. Students study a wide variety of specialised modules tailored to their chosen course as well as receiving training in communication and presentation skills. All third year students have the opportunity to meet with past graduates of the School of Physics through the ‘Wild Geese’ programme where they receive guidance on building a career in physics.

During the fourth year, students carry out a research project in either an academic or industrial research laboratory, the duration and the topic of which is also tailored to their specific course. Many students carry out their final year project abroad, mainly across Europe, Canada and America. This unique opportunity allows our students to develop their practical skills in a research environment, while learning about different countries and cultures.


Quantum Mechanics, Electromagnetism, Condensed Matter Physics, Atomic and Nuclear Physics, Stellar and Galactic Structure, Statistical Mechanics, Dynamical Systems, Practical in Physics.


Quantum Physics, High Energy Physics, Condensed Matter, Nanoscience, Electromagnetic Interactions, Modern Optics, Advanced Topics in Physics and Practical in Physics.

Study abroad

Physics students may undertake their nine-week fourth year project at a university in the EU or further afield, provided they attain a sufficient standard in the third year examinations. In recent years, students have worked at the Belgian Nuclear Research Centre, at the Universities of Potsdam and Regensburg in Germany, at the NASA Goddard Space Flight Center in the United States and at the European Space Agency in Madrid.

The Trinity physics degrees are all recognised by the Institute of Physics, which is the professional body for physicists in Ireland and the UK, as qualifications for the professional title ‘Chartered Physicist’ (CPhys). Physics graduates are always in high demand in Ireland and abroad in modern high-technology industries, as well as in teaching. You may also find a career in academic institutions, government and industrial research organisations and production facilities or in the meteorological service. There are diverse opportunities in electronics, telecommunications, biophysics, hospital and health physics, automation and computing. Your degree course will give you the opportunity to acquire problem solving skills which will be valued by your future employer. It could also give you useful primary training for a legal, managerial or actuarial career, where a technical background is attractive.

Graduate Profile

Michael Byrne

After four great years studying Physics at Trinity, I headed to Oxford for an M.Sc. degree in applied mathematics before beginning a PhD in climate science at MIT.

I spend most of my time running climate simulations under the supervision of another Trinity Physics graduate, Paul O’Gorman. This involves extensive use of the coding skills I honed in the undergraduate computer lab practicals in the School of Physics. Research questions I’m working on include: Why, under global warming, do land temperatures increase more than ocean temperatures? How will the terrestrial water cycle change in the future? What effects do land surface properties have on monsoon circulations?

Graduate profile

Patrick Kenny, Chief Physicist at the Mater Misericordiae University Hospital since 1998.

"I graduated from Trinity in 1982 with an honours degree in Experimental Physics. My Master degree (Physical Sciences in Medicine) is also from Trinity, and I hold a PhD in physics from UCD. At the Mater I am responsible for ensuring that medical physics support services provided by our 9 hospital physicists safe, high quality and cost-effective.

Coming from a basic rural background, my access to a university education was hindered by ignorance of university entrance requirements. Trinity was the only university in Ireland in which I could study my favourite school subject, physics, to degree level.

University learning is about much more than just attending lectures and passing exams (although that's quite important too!). It's about developing and testing skills required throughout life. The compact nature of Trinity's campus encouraged interactions and appreciation of people from diverse backgrounds. At Trinity I studied hard and played hard - in my third year I was vice-captain of the Athletics Club.

My appreciation of the true value of my physics degree and the scientific problem-solving skills it imbues continues to grow. Modern Medicine involves many sophisticated physics applications for diagnosis and treatment of illness, e.g., CT x-ray machines. Basic physics principles learned at undergraduate level in Trinity are applied to understand and optimise such complex and potentially hazardous systems."
