Query: What is the Scale of Supersymmetry Breaking   For a long time, it has been widely assumed that if the underlying laws of
nature are supersymmetric, supersymmetry is broken at a scale intermediate
between the weak scale and the Planck mass. The construction of realistic
models of dynamical supersymmetry breaking in which supersymmetry is broken at
a much lower scale, as well as a growing appreciation of the supersymmetric
flavor problem has reopened this question. After reviewing some ideas for
understanding the microscopic origin of the soft breaking parameters in the
context of string theory, I turn to low energy breaking. Independent of the
details of the underlying theory, events with photons and missing energy, like
the CDF $e^+e^-\gamma \gamma \not{E}_T$ event, are likely signals of low energy
breaking. I briefly review the predictions of the simplest model of low energy
supersymmetry breaking for the soft breaking parameters (MGM), and then ask
what sorts of generalizations are possible. It turns out that if all couplings
are weak, there are only a limited number of ways to modify the model.
