Randy and Jim about the perspectival nature of quanta, the Unruh effect, which says that for highly accelerated systems, additional particles and temperature will be seen.

  • Leonhardt, U. and Philbin, T., Geometry and Light: The Science of Invisibility (2010). This is a textbook on using the methods of general relativity in the behavior of light in nonlinear materials that I quite enjoyed when I read it. It starts off with an old favorite, variational principles, like Fermat's principle of least time, and passes through a short course on differential geometry, before mixing light and geometry with Maxwell's equations. After that, he discusses optical analogs of black holes, the optical Aharonov-Bohm effect, and other topics -- like "cloaking at a distance:" invisibility! It has full color illustrations, which helps with differential geometry, and better, it's a Dover book so its cheap! [Amazon].
