Most of the laws of physics are expressed in the form of
differential equations; that is our legacy from Isaac Newton. The
customary separation of the laws of nature from contingent boundary
or initial conditions, which has become part of our physical
intuition, is both based on and expressed in the properties of
solutions of differential equations. Within these equations we make
a further distinction: that between what in mechanics are called
the equations of motion on the one hand and the specific forces and
shapes on the other. The latter enter as given functions into the
former. In most observations and experiments the "equations of
motion," i. e., the structure of the differential equations, are
taken for granted and it is the form and the details of the forces
that are under investigation. The method by which we learn what the
shapes of objects and the forces between them are when they are too
small, too large, too remote, or too inaccessi ble for direct
experimentation, is to observe their detectable effects. The
question then is how to infer these properties from observational
data. For the theoreti cal physicist, the calculation of observable
consequences from given differential equations with known or
assumed forces and shapes or boundary conditions is the standard
task of solving a "direct problem. " Comparison of the results with
experiments confronts the theoretical predictions with nature."
