Subject Description

This subject will provide students with:

• comprehension of how physics problems are formulated, analysed and solved using a wide range of theoretical methods;

• an ability to apply these methods to a wide range of physical situations;

• a grounding in relevant theoretical methods for those with an experimental orientation.

This subject provides an introduction to:

• Linear systems: time and frequency representation, natural modes of coupled systems, Fourier, Laplace, Mellin and Hankel transform techniques. Stability and causality.

• Symmetry in physical systems: Group theory and physical applications - angular momentum, isospin, crystallography.

• Potential theory for electrostatics, magnetostatics and gravitation in 2 and 3 dimensions: solution by functions of a complex variable, Bessel and Legendre functions, Green functions. Integral equations.

• Waves and diffusion in 1, 2 and 3 dimensional continuous and discrete spaces: strings, lattices, drum skins, acoustics and heat conduction.

Assessment

A 2.5 hour end-of-semester written examination, plus tests and/or assignments, set during the semester, which may account for up to 20% of the final mark.
