They have paid considerably less attention to sciences such as chemistry and nanoscience, where not only are the subjects distinct, but the very aims differ: chemistry and nanoscience center around synthesis. Methods associated with synthesis do not fit well with description, explanation, and prediction that so dominate aims in philosophers' paradigm sciences. In order to synthesize a substance or material, scientists need different kinds of information than they need to predict, explain, or describe. Consequently, they need different kinds of models and theories. Specifically, chemists need additional models of how reactions will proceed. In practice, this means chemists must model surface structure and behavior, because reactions occur on the surfaces of materials. Physics, and by extension much of philosophy of science, ignores the structure and behavior of surfaces, modeling surfaces only as \boundary conditions" with virtually no influence on material behavior. Such boundary conditions are not seen as part of the physical laws that govern material behavior, so little consid- eration has been given to their roles in improving scientists' understanding of materials and aiding synthesis.
