Abstract

A brief history of quantum gravity will be reviewed in this talk. Various aspects of quantum gravity ranging from the failure of perturbative treatments to the alternative formulations of quantum gravity such as supergravity and superstrings will be discussed at an informal level. The main emphasis of this review will be on the loop representation of non-perturbative quantum gravity.
