Query: Les Houches Lectures on Fields, Strings and Duality   Notes of my 14 `lectures on everything' given at the 1995 Les Houches school.
An introductory course in topological and conformal field theory, strings,
gauge fields, supersymmetry and more. The presentation is more mathematical
then usual and takes a modern point of view stressing moduli spaces, duality
and the interconnectedness of the subject. An apocryphal lecture on BPS states
and D-branes is added.
