Abstract: Science is concerned with describing the world. Mathematics is an important tool. One can use Mathematics to write equations for how a system will change over time. To get manageable equations, the usual procedure is to suppress some of the parameters which play a part in the system. This simplifies the Mathematical equations. It is important to ask whether the Mathematical results still describe the situation accurately. In this paper, we will investigate rigorously whether one can recover precise results when one suppresses some variables. We will do this in the case of one dimensional complex dynamics, where the exact theory is highly developed.
