TEXT B Computer programmers often
remark that computing machines, with a perfect lack of discrimination, will do
any foolish thing they are told to do. The reason for this lies, of course, in
the narrow fixation of the com puting machine’s "intelligence" on the details of
its own perceptions its inability to be guided by any large context. In a
psychological description of the computer intelligence, three related adjectives
come to mind: single- minded, literal-minded, and simple-minded. Recognizing
this, we should at the same time recognize that this single-mindedness,
literal-mindedness, and simple-mindedness also characterizes theoretical
mathematics, though to a lesser extent. Since science tries to
deal with reality, even the most precise sciences normally work with more or
less imperfectly understood approximations toward which scientists must maintain
an appropriate skepticism. Thus, for instance, it may come as a shock to
mathematicians to learn that the Schrodinger equation for the hydrogen atom is
not a literally correct description of this atom, but only an approximation to a
somewhat more correct equation taking account of spin, magnetic dipole, and
relativistic effects; and that this corrected equation is itself only an
imperfect approximation to an infinite set of quantum field theoretical
equations. Physicists, looking at the original Schrodinger
equation, learn to sense in it the presence of many invisible terms in addition
to the differential terms visible, and this sense inspires an entirely
appropriate disregard for the purely technical features of the equation. This
very healthy skepticism is foreign to the mathematical approach. Mathematics
must deal with well-defined situations. Thus, mathematicians depend on an
intellectual effort outside of mathematics for the crucial specification of the
approximation that mathematics is to take literally. Give mathematicians a
situation that is the least bit ill-defined, and they will make it well-defined,
perhaps appropriately, but perhaps inappropriately. In some cases, the
mathematicians’ literal-mindedness may have unfortunate consequences. The
mathematicians turn the scientists’ theoretical assumptions, that is, their
convenient points of analytical emphasis, into axioms, and then take these
axioms literally. This brings the danger that they may also persuade the
scientists to take these axioms literally. The question, central to the
scientific investigation but intensely disturbing in the mathematical context
what happens if the axioms are relaxed--is thereby ignored. The
physicist rightly dreads precise argument, since an argument that is convincing
only if it is precise loses all its force if the assumptions on which it is
based are slightly changed, whereas an argument that is convincing though
imprecise may well be stable under small perturbations of its underlying
assumptions. (419) The author suggests that a mathematician asked to solve a problem in an ill-defined situation would first at-tempt to ______.
A.identify an analogous situation B.simplify and define the situation C.vary the underlying assumptions of a description of the situation D.determine what use would be made of the solution provided
