Part III

If you are thinking about a career in research, you should consider taking the optional Part III, which leads to the degree of MSci.

At this level you will be studying your subject at the edge of what is known. You will be reading research papers published by experts in the field from all over the world and attending lectures given by members of staff actively researching the topics covered. The emphasis on self-directed learning increases. You will be given the opportunity to gain highly specialised knowledge and considerable research experience, with support and guidance. A wide choice is offered so that you can follow up lines of work in which you are particularly interested.

Students who wish to continue their studies to a fourth year take one subject from:

• Astrophysics
• Biochemistry
• Chemistry
• Earth Sciences
• History and Philosophy of Science
• Materials Science
• Physics
• Systems Biology
• Quantitative Climate and Environmental Science

These subjects have entry requirements, often a class 2.1 or above in a relevant Part II subject.

The course is enriched by a vibrant seminar programme but the highlight, for many, is the Easter field trip to southeast Spain. Seminars offer a window into cutting-edge research and professional practice, while the field trip provides hands-on geological experience. Throughout, you’re encouraged to engage deeply; to ask questions, take notes, and explore topics beyond the syllabus. This rigorous programme leads to a fully accredited honours geology degree, ideal for careers or further study in Earth Sciences.

History and Philosophy of Science

Explore the big questions behind science. Dive into the deeper questions behind how science works, how it shapes society and how it has evolved over time. You’ll explore the philosophical, historical and social dimensions of science, while developing advanced research and writing skills and gaining expertise tailored to your interests.

At the heart of the course are weekly seminars, where you’ll engage with peers and academics, culminating in two assessed essays. You’ll also write two substantial research papers, present your ideas in academic settings, and take part in the department’s vibrant programme of seminars and reading groups. The year builds towards your major dissertation project – a chance to showcase your original research and contribute meaningfully to the field.

Placing a strong emphasis on independent learning, critical analysis and original research, Part III HPS is ideal for those aiming for a PhD, a career in science communication, policy or education, or those who simply want to understand science in a deeper, more critical way.
