DESCRIPTION:The twistor approach to four-dimensional geometry has been\nver
y fruitful for physicists working in Minkowski space-time as well as\nfor m
athematicians working in Riemannian (positive definite signature)\ngeometry
. It also provides a framework for relating these two subjects\nvia analyt
ic continuation.\n\nThe way symmetries work in a quantum field theory chang
es significantly\nwhen one formulates such a theory in positive definite si
gnature. I'll\nargue that in this context the symmetries of twistor theory
match well\nthe symmetries of the Standard Model as well as a chiral formu
lation of\ngeneral relativity\, providing an intriguing possibility for a u
nified\ntheory.
