- I think it is unreasonable to teach mathematics under the pretext that it
- is useful and NOT to also teach the proper use of computational tools that
- they are likely to need when actually putting mathematics to use. As a
- numerical analyst it would be hard for me to lose sight of the fact that
- some problems cannot be solved analytically. Even when analytical
- solutions are possible, evaluating them may be far less efficient and
- reliable than a numerical solution. That numerical solutions may be
- "incorrect" hardly needs comment.
-
- This question pops up from time to time, and the strongest reactions
- occur when someone suggests a total abandonment of hand calculation
- or a total abandonment of modern computational tools (in the context
- of education). Either extreme is a poor choice IMO. Why must we
- go to an extreme?
