What is Science?

Science is making critical contributions to conservation and the new world economy, and to our health and welfare. Scientific knowledge had been used to develop modern medicine, the mobile phone, the worldwide web, and new ways to save and generate energy. There is much to learn and much more to be discovered. Discoveries made by scientists have changed our world. We have a deep understanding of how the natural world works. We know much about how the physical world evolved from the Big Bang 13 billion years ago, how our planet evolved from stellar debris and how modern man diverged from other hominids in the last 150,000 years. We know the structure of DNA and the genetic code of a human being, the TB bacterium, of rice and many other organisms.

Why study Science at Trinity?

Science is diverse, progressive and exciting. It provides students with a broad foundation in Science (student choose 3-4 subjects for their first two years), followed by the opportunity to specialise in one of 16 areas for their final two years. Graduates of this course have excellent career prospects across the whole spectrum of the sciences. The Science course in Trinity offers:

  • Outstanding teaching by scientists and mathematicians who are at the forefront of their field worldwide.
  • Research-led teaching by world leaders in their fields.
  • Excellent laboratory facilities.
  • Field and laboratory work supported by many subjects.
  • Continuously updating and revising course structures ensuring excellent qualifications.
  • Opportunities for study abroad before and after graduation.
  • Opportunities to carry out research as part of your course.
  • Excellent career prospects in Ireland and abroad.

What will I study?

A key feature of the first year in Science at Trinity is that you don’t have to choose your modules before you start. On your first day you will meet with scientists who will advise you on your options. Courses in the first two years are designed to introduce you to and train you in the fundamental sciences. By the end of the second year you will have moved far beyond the extent of science as it is taught at school and will understand better where your real interests lie. At this point you have the opportunity to focus on one of sixteen specialist areas for your final two years.


Choose modules to the value of 60 credits for the year (30 per semester) from the following subjects:
Biology (20), Chemistry (20), Geography (20), Geology (10), Mathematics (20), Physics (20), Foundation Physics (10).

Graduate Profile

Ciara Maguire
First Year Science Student and Intel Women in Technology Scholar
I have always had a keen interest in science and a curiosity for the world around us. The general science course at Trinity is perfect for me. I have the opportunity to explore a variety of scientific fields before specialising. I chose Trinity as its science departments are internationally renowned and it is a college at the forefront of scientific discoveries. I relished the thought of such a challenging and inspiring atmosphere.
In addition to the academic elements of College life I am also enjoying and embracing all that the College has to offer. Each week presents new, interesting and exciting events.
Coming to Trinity has opened a window of opportunities, the many societies and clubs have allowed me to learn new skills as well as meet new and interesting people. The vibrant and inclusive atmosphere on campus reassures me that I have made the right choice coming to Trinity.
