Notes briefly introducing the basic definitions of twistor theory, which might provide an "elegant formalism for both general relativity and quantum theory. Roger Penrose was first led to the concept of twistors in his investigation of the structure of spacetime, and it was he who first saw the wide range of applications for this new mathematical construct. Yet 30 years later, twistors remain a relatively obscure and unfashionable research area in mathematical physics." Introduction; spinors; electromagnetism in spinor notation; twistors; quantization; Klein correspondence; and classical fields.
