A summary of work done in collaboration with K. Rajagopal and E. Shuryak. We
show how heavy ion collision experiments, in particular, event-by-event
fluctuation measurements, can lead to the discovery of the critical point on
the phase diagram of QCD.Comment: 4 pages. Summary of work done in collaboration with K. Rajagopal and
E. Shuryak (hep-ph/9903292). To be published in the proceedings of Quark
