Joel Franklin is a Professor in the Physics Department of Reed College, Oregon. His work focuses on mathematical and computational methods with applications to classical mechanics, quantum mechanics, electrodynamics, general relativity, and modifications of general relativity. He is author of two previous titles: Advanced Mechanics and General Relativity (Cambridge, 2010) and Computational Methods for Physics (Cambridge, 2013).
'The style of the book is quite informal … but the computations appear to be correct, complete and suitable to the scope of the book. … The appendices about mathematical methods can be a good refresher for what was learnt in math courses and will suffice for understanding the mathematics in the different sections.' Giovanni Rastelli, Zentralblatt MATH
