Abstract: In 1997, J Maldacena proposed a correspondence
between gravitational theories near black holes in the bulk of anti-de Sitter (AdS) spacetimes and conformally invariant gauge field theories (CFT's) on the boundaries.

The AdS/CFT correspondence is by now regarded as one of the deepest insights into physical theory, and with almost 10,000 citations, Maldacena's paper is one of the most cited papers of all time.

Recently, J Rasmussen brought to my attention the fact that there are examples of AdS/CFT where the CFT's are of the same nature as those used to describe surface critical phenomena.

The limited aim of this talk is to outline a derivation of Cardy's formula for the entropy of a conformal field theory and to explain its role in this very vast subject.
