- You are certainly correct, they'll get you flamed. Could you show us some
- evidence?
-
- Ok, let's take Simon a few steps further (and get myself flamed, too). All
- Mathematica is is a tool. Just like the decimal number system. Would you have
- us give up our positional number system for something else like Roman numerals?
-
- I don't believe you understand the purpose of tools.
-
- How are we to stand on the shoulders of those before us (as Newton said) with
- people spouting rhetoric like this?
-
- I would guess that using tools like Mathematica to derive tedious results will
- be viewed much the same way in 50 years as we view grabbing a handheld
- calculator to do square roots today. It won't be given a second thought.
-
- Simon, do you still force your students to figure square roots by hand? Do you
- force them to learn to figure them by hand before allowing them to use a
- handheld calculator? Do you believe that your students understand what a
- square root is without having to go through the fun and excitement of figuring
- them by hand? (I should say at this point that I found it very interesting
- when I learned how to figure square and cube roots by hand, but I'm just not
- that interested in doing it every time I need to take a root.)
-
- Well, let me remind you that people used to go to college to master the art of
- multiplication and division, things which we gripe about if they aren't
- mastered in junior-high-school today. In the same spirit, we will take
- symbolic manipulation software for granted someday.
-
- If your curriculum isn't compatible with today's technology, then maybe you
- need to change the content of your courses. Technology certainly will not stop
- falling into the hands of the next generation simply because you and a few
- others want it to stop.
-
- People like this should dedicate their lives to safeguarding the past instead
- of preventing the next generation from moving on into the future.
