  Or one can emphasize similarity in the opposite way. One can emphasize the degree to which experimental targets are always chosen as surrogates for what’s really of interest.  Morrison, 2009 is probably the most forceful defender of emphasizing this aspect of the similarity of experiment and simulation.  She argues that most experimental practice, and indeed most measurement practice, involve the same kinds of modeling practices as simulations.  In any case, pace Peschard, nothing but a debate about nomenclature—and maybe an appeal to the ordinary language use of scientists; not always the most compelling kind of argument—would prevent us from saying that the epistemic target of a storm simulation is the computer, and that the storm is merely the epistemic motivation for studying the computer.
