The scalar-tensor theory of gravitation moved into the limelight in recent years due to developments in string theory, M-theory and "brane world" constructions. This book introduces the subject at a level suitable for both graduate students and researchers. It explores scalar fields, placing them in context with a discussion of Brans-Dicke theory, covering the cosmological constant problem, higher dimensional space-time, branes and conformal transformations.
