Lecture notes

When I'm preparing new lecture courses I frequently find it very useful to consult notes that other lecturers have put on their web pages for their students. So with absolutely no guarantee and in the hope that they will be useful here are some of mine.

• Equations of motion in electrodynamics This is my tribute to the late Professor Alessandro De Vita.
• Fields and Waves First year physics course, taught at King's College 2014-2017. Mostly oscillations, resonance, electrostatics and magnetostatics in vacuum.
• Solid State Physics Third year course taught at Queen's University Belfast, 2007-2012.
• Electronic Structure Graduate lectures, mostly density functional theory.
• Elastic and inelastic scattering of electrons.
• Lecture notes on Steel delivered at Imperial College, 2015-2018
• A jolly lecture on quench and tempering.
• The complete lecture notes and lecture slides.
• Notes on solid state diffusion.
• Notes on solubility products in microalloy steel. (With Vivian Tong, now at NPL I fear)
• For electrochemistry notes, see QuantumCorrosion.org
