Summary  This course is designed for prehonours direct entry physics students. It provides an introduction to classical dynamics, waves, special relativity and quantum physics. It serves both as a preparation for further study in physicsbased degree programmes, and as a standalone course for students of other disciplines, including mathematics, chemistry, geosciences, computer science and engineering.
The course consists of lectures to present new material, and workshops to develop understanding, familiarity and fluency.

Learning Outcomes
On completion of this course, the student will be able to:
 State the basic principles of classical dynamics, special relativity and elementary quantum mechanics and the regimes in which the different theories apply.
 Apply these principles in conjunction with elementary mathematical techniques to solve simple problems in classical, relativistic and quantum mechanics.
 Present a solution to a physics problem in a clear and logical written form.
 Assess whether a solution to a given problem is physically reasonable.
 Locate and use additional sources of information (to include discussion with peers where appropriate) to facilitate independent problemsolving.
