Twistor Theory II: More Recent Developments. General Relativity, High-Energy Physics, Twistor Strings An obstruction to developing twistor theory into a full-blown framework for physics has been the incorporation of right-handed helicities (the "googly problem") into the non-linear interactions of Eintstein and Yang-Mills theory, the left-handed ones being already described in elegant twistor terms. Some recent progress will be described, as will developments in simplifying calcuations in high-energy physics which followed from ideas introduced by E. Witten and others, where concepts from string theory are united with those of twistor theory.
