An interesting read, especially given the substantial coverage of twistor space. However, the description of twistors has left me none the wiser, so I've had to order formal textbooks on the topic. Moreover, the author treats certain physical assumptions as facts (e.g. he states repeatedly that neutrinos have zero rest mass, which is now known to be false).
