Weakly emergent properties are characteristic of complex systems in nature. See also: System dynamics.
The equations we choose often reflect a compromise between what we think best describes the phenomena and computational tractability. Whether or not the pendulum's inner fulcrum is held fixed a fact which will determine whether the relevant model is analytically solvable has no bearing on the semantics of the elements of the model.
A defense of the epistemic power of simulations against Morgan's argument could come in the form of a defense of the identity thesis, or in the form of a rejection of the epistemological dependency thesis.
Computer simulation in education
The concepts of verification and validation has drawn some criticism from philosophers. Interactive: Learners work interactively with a simulation's model to input information and then observe how the variables in the simulation change, based on this output. The idea of a model organism in biology makes this idea perspicuous. Take the fable of the grasshopper and the ant. Hacking, I. Bedau, M. He noted the gap between human and chimpanzee intelligence, despite the fact that we share more than 98 percent of our DNA. Of course, this view about experiments is not uncontested. Frigg, R. Stochastic models use random number generators to model chance or random events; A discrete event simulation DES manages events in time. And there are other reasons to think we might be virtual.
Validation, on the other hand, deals with physics and addresses the appropriateness of the model in reproducing experimental data.
We have good reason to think, in other words, that there are model equations out there that enjoy better empirical support, in the abstract.
Silogen atoms are fictions.
Reference Terms from Wikipedia, the free encyclopedia Computer simulation A computer simulation or a computer model is a computer program that attempts to simulate an abstract model of a particular system. But Purves takes this failure of PI to be constitutive of a fiction, rather than merely symptomatic of them. However, psychologists and others noted that humans could quickly perceive trends by looking at graphs or even moving-images or motion-pictures generated from the data, as displayed by computer-generated-imagery CGI animation. These kinds of multiscale models, in other words, cobble together the resources of theories at different levels of description. A two-dimensional model might be used to simulate the drag forces on the cross-section of an aeroplane wing. One can emphasize the degree to which experimental targets are always chosen as surrogates for what's really of interest. It is unlikely that there are very many real examples of computer simulations that meet their strict standards.
Nonetheless, as the average humidity increases, average cloudiness will also increase—hence there could be a parameter linking average cloudiness to average humidity inside a grid box.
Because digital computer mathematics is not perfect, rounding and truncation errors multiply this error, so it is useful to perform an "error analysis"  to confirm that values output by the simulation will still be usefully accurate.
Thus, he wants to find an intrinsic characterization of a scientific fiction.
