This is a companion volume to our introductory work Spinors and space-time, Volume 1: two-spinor calculus and relativistic fields. There weattempted to demonstrate something of the power, utility and elegance of2-spinor techniques in the study of space-time structure and physical fields,and to advocate the viewpoint that spinors may lie closer to the heart of(even macroscopic) physical laws than the vectors and tensors of thestandard formalism. Here we carry these ideas further and discuss someimportant new areas of application. We introduce the theory of twistorsand show how it sheds light on a number of important physical questions,one of the most noteworthy being the structure of energy-momentum/angular momentum of gravitating systems. The illumination that twistortheory brings to the discussion of such physical problems should lendfurther support to the viewpoint of an underlying spinorial structure inbasic physical laws.
