Summary  This is an introductorylevel course, giving an overview of a range of topics, including thermal physics, waves, elementary quantum mechanics, properties of matter, nuclear and particle physics, and astrophysics. The course is designed for those with qualifications in physics and mathematics at SCE Higher level or equivalent. It serves both as a preparation for further study in physicsbased degree courses, and as a standalone course for students of other disciplines, including (but not limited to) mathematics, chemistry, computer science and engineering. The course includes an experimental laboratory element.
