Approximations

... you have is that species is a taxonomic approximation. An owl defines an organism with a certain similar phenotype. They are unique and DEFINABLE. Approximations are used in chemistry also. One example is in stoichiometry. Moles are approximations of the number of atoms or molecules for an element ...

... of numbers and logic. To apply mathematics to the real world, you need to assess which factors are important to your model and make appropriate approximations. So, consider the ideal gas law which is a purely mathematical model of gas behavior(assuming molecules are tiny and have no affinity ...

... entropies. With the revolution in computer power continuing, these problems are ripe for study but require the judicious choice of algorithms and approximations. We provide a critical evaluation of several numerical approaches to the thermodynamic decomposition of free energies and summarize applications ...
