“Science and everyday life cannot and should not be separated.” Rosalind Franklin, Chemist and X-ray crystallographer

Humans have always relied on chemistry to shape the way we live – from metal work in the Copper Age 5000BC, to today’s digital innovation and emerging areas of science such as bioscience and nanoscience.

In the coming century, the real-world application of chemistry will be critical to key problems we face as a society, including sustainable energy, food security, medicine, managing our environment and providing clean air and water.


Chemistry opens up a whole world of opportunities for the future. It is required for a number of degrees courses, including: medicine, veterinary, forensic science, dentistry, physiotherapy, biological sciences, pharmacy and environmental science.

Studying chemistry also opens us career options in diverse sectors, including banking, education, law and business.
