Janos.....

I regard this as such an excellent example.....it shows that young people 
can become very curious about the possibilities with Mathematica.....I get 
the impression that Mathematics is now , in fact, much more interesting for 
your boys.....they can do things....and see things......suddenly mathematics 
comes alive for them in ways that perhaps were not possible in any other 
way.....and I'll wager that they will work much harder at mathematics then 
they ever did before.....all because now, thanks to Mathematica, it is much 
more interesting to them....I see them potentially exploring the 
fundamentals of mathematics with much more depth and intensity then, 
perhaps, they would have before.....is there anyone out there who really 
thinks that mathematics is that interesting to the average young person and 
that we dont have to do something, anything, to make it interesting for 
them???

So I think that another important element of this issue of using Mathematica 
for Education is simply this......what is the interest factor for a 
student?.....will students work , perhaps, twice as hard when given the 
opportunity to use Mathematica because of all the possibilities  for 
"exploration"  (to use Paul Abbott's word)???

I certainly think so....an unequivocal YES to the question as far as I'm 
concerned......
