Hello....

I'm that "student" by the way.....and actually I'm 61 years old.....I 
decided to go back to school and take a course in Electromagnetics 
especially now that I had a tool like Mathematica to work with.......I write 
this reponse because I wonder why you wrote  "proudly 
proclaimed"...?......as if I should be criticized for what I had done.....as 
if the enjoyment that I get from using Mathematica, in whatever way I can to 
help me improve my work and , actually, to enjoy it all the more, deserves 
some kind of criticism, especially this  idea of the glory of 'pencil and 
paper'....in fact, now I have this 'beautiful' Notebook with all my 
calculations, clear as a bell.....which I can use over and over again 
whenever I need ....which I can re-read easily.....and soon I will take the 
second sequence in the course........I've worked with a theorist at 
work...and I've watched him write pages and pages of 'pencil and 
paper'....and often to find a mistake on the first page....and then have to 
re-do all the other pages...it took me years of coaxing and convincing to 
get him to use Mathematica.....and that's because , like you, he believed in 
this assinine idea of "a fool with a tool is a fool"....he just didnt get 
it.....now he finally uses Mathematica ....and has learned that when he 
makes a mistake on the first page, he only has to correct that, re-run his 
program and then get 'correct' results....took me 5 years of continual 
persuasion to get him to use Mathematica......."No, a fool who wants to be a 
fool  , remains a fool....a fool who finds a tool and works hard at it  and 
learns how to use it and learns from a group like Mathgroup how to use it 
correctly is no longer a fool or, at least, he's much less of a 
fool"....and, as far as Mathematica goes, I find myself a very happy 
scientific fool....

I think you really misunderstand the nature of the average scientist and 
engineer....he wants to improve his technical skill at all 
costs.....Mathematica and Mathgroup have helped me enormously to improve my 
technical skills.....and by the way, I always use a calculator to add 
numbers and fractions....always....because I hate that idiotic and tedious 
procedure....and when I do it by hand, I invariably come up with the wrong 
result.....much better to be a fool and use a calculator and get the right 
result...

Let me ask this....if using Mathematica is so easy, so straight forward, and 
so on, then why is there Mathgroup at all??...

And the answer is really very simple.....it's not....and knowing the math 
and how to use it is not straight forward....and the number of interesting 
and enlightening comments by the people in Mathgroup who are very  astute at 
mathematics  and who explain the math behind the commands is very 
enlightening......

I have learned that those people who know only the Mathematica Command 
structure will not really get very far with Mathematica.....and that only 
those people with 'in depth' comprehension will ever get the full benefits 
of Mathematica....I am not mathematically astute....so I have to have 
Mathematica help me....but I always try to learn from it....in any way that 
I can....it and Mathgroup have helped me in countless ways to understand 
mathematics better.....and since I'm a physicist this learning has been 
invaluable to help me understand physics much better...hence, the final 
result, that is, much more enjoyment in the work that I do....which is 
really the bottom line, for me anyway.....
