The point was in response to the idea that the secondary school
curriculum should somehow include some of the "new mathematics
developed since world war II". I know a portion of that math, and have
a passing familiarity with a lot more (and am quite ignorant of somem
I'll confess -- but this is true of most mathematicians, I think), and
I doubt that much of it has any role in the secondary math curriculum.

I don't remember getting that impression in my English or history classes,
but no matter.

In any case, while one can quibble at the details, the fact remains:
there is an enormous core of mathematics that is pretty rock-solid. A
vague awareness of those hammering away at the frontiers of knowledge
is fine -- but what specifically do you want to teach about those

Of course, actuarial science is ALSO a dynamic, growing field -- even
in its pure mathematical components. How much of a problem is/was it to you
that you feel otherwise?

Actually, I doubt many students graduate high school even knowing what
actuaries do. So perhaps your condition was an improvement over the

Isn't the study of latin also constantly evolving, etc.? But I can
agree with this, up to a point. I certainly think it's useful to
stress that the math in the textbook wasn't made all at once and just
for the purpose of filling a textbook. Historical context in its
development and refinement can give a broader sense of the power and
dynamism of math -- in the sense that one sometimes applies ones tools
to a problem and sometimes one first has to craft the tools
themselves. I could also see including all the false starts and errors
in the history of math that tend to drop out of the finished textbook
and give too pat an impression.

(I'm not sure that spending time in math class talking about Greek
drama is such a good idea -- kids may pick up the wrong message from
the desire of a teacher to talk about something other than the subject
he or she is supposed to be enamored of.)

Still, ultimately, the speed which with math will be forgotten may
have more to do with whether you can make students see either the
power, utility or beauty of what they learn, quite apart from whether
they think it was discovered last week or two thousand years ago.
