Realism is a position that what science produces not only works and permits the production of accurate predictions but really does represent and/or describe the actual situation in nature as known by some omniscient entity. Of course, one of the central limitations of science is that the “true” nature of reality can never be known because there is no omniscient entity to ask. Science was invented, at least in part, to answer questions about the natural world and get as close to “the truth as possible, but no bell rings or light blinks to tell scientists that they have found the truth. Another philosophical precept is that as long as the scientific ideas function properly and are consonant with all of the evidence it does not matter whether they correspond with reality or not.

The ideas are useful and descriptive and that should be the end of it. With this distinction between realism and instrumentalism in mind we can now turn to the idea of a scientific model. Although no survey has ever been taken on this issue, it seems logical that scientists do believe that they are not just producing useful ideas but that their ideas and descriptions correspond to a reality external to the scientists themselves.
Certainly the average person believes this to be true. It is doubtful that anyone seriously questions the model suggested by the kinetic molecular theory of matter which pictures atoms and molecules as tiny discrete balls that have elastic collisions, thus explaining whole ranges of phenomena.
