- Hmmm. This is one opinion, but it is not shared by all mathematicians or
- scientists.
-
- Mathematicians are engaged in the study of phenomena. The phenomena --
- mathematical entities -- may not be "hard" material objects like rocks,
- planets or biological organisms, but they are phenomena nevertheless:
- they exist in some way because we can perceive (or conceive of) them.
- The science of mathematics includes the quantitative analysis of these
- mathematical entities, and it uses the same scientific method as the
- other branches of science, namely observation, hypothesis, logic and
- experiment.
-
- A mathematician may make a conjecture about a certain mathematical
- object, which is then made the subject of experimental study. If the
- experiments turn up anything which contradicts the conjecture, then it
- is rejected or modified. If no contradictory evidence is found, then --
- just as in other branches of science -- the conjecture can be regarded
- as SUPPORTED by the evidence, although not PROVEN by it.
-
- Or, a mathematician may arrive at a conclusion about a certain
- mathematical object by directly reasoning from accepted principles. In
- that case -- just as in the other branches of science -- the conclusion
- can be regarded as PROVEN, given that the accepted principles are true.
-
- Viewed in this way, mathematics can be seen as a branch of science. We
- are all familiar with the famous statements of Gauss and others about
- the standing of mathematics as a science. They had good reason to make
- those statements. Of course, one can get carried away by
- compartmentalization, in which case one might say that mathematics is
- mathematics and science is science. But this tendency to divide
- everything into categories often obscures issues. In fact, the secret of
- scientific achievement is to be expert at seeing how two superficially
- things are really manifestations of one principle.
-
- Mathematical objects and physical objects are both components of
- reality, they are both perceivable (or at least conceivable) by the
- mind, and they can both be studied under the same scientific method.
-
- Sincerely,
- Kalki Dasa
