Physics
Physics is the fundamental science that drives modern technologies; items such as smartphones, iPads, fibre-optics, lasers, GPS satellites, solid state drives, radiotherapy beams, smart sensors, medical imaging systems, are all applications of physics.
With regard to the environment, physicists are actively involved in research aimed at better understanding and protecting the natural world.
Knowledge of the physics that underpins modern technological developments allows us to conceive of previously unforeseen devices and applications.
If you are interested in how things work, and have an enquiring mind, then this could be the course for you.
