What is Science?

Science is about knowledge: the generation of knowledge through research and its acquisition through learning. Scientific investigation allows us to understand the world around us: how the physical world has evolved and changed since the Big Bang and how life has advanced into complex, diverse forms. The application of scientific knowledge has led to world changing developments such as modern medicine, the mobile phone and efficient methods of energy production. As we acquire new knowledge, our understanding of the world changes which in turn leads to new and better applications. There is still much to discover and new applications to be developed. Do you want to contribute?

Is Science the course for you?

Science at Trinity is offered through four different entry routes leading to an Honours degree following four years of study. We offer students opportunities to choose from four entry streams:

  1. Biological and Biomedical Sciences.
  2. Chemical Sciences.
  3. Geography and Geoscience.
  4. Physical Sciences.

These four entry routes lead to one of 20 exit routes. The programme will offer students a detailed knowledge and thorough understanding of the scientific method. Students will learn scientific skills while developing an understanding of the role and Influence of science on society
