Not especially,. just illustrative.

I have no problem with physicists (etc) teaching each other programming, 
as long as they
don't think that they know "computer science" as a consequence of 
knowing a little FORTRAN.

I have met physical scientists who assume that a computer scientist 
knows LOTS of programming languages, not just FORTRAN.  I have seen programming languages designed by physicists who tried to learn by osmosis, but made some fundamental errors.

Microwave ovens can be fairly complicated, with power settings, times, and extra features like convection, buttons for defrost,  and "popcorn"....  But I would not confuse "how to use a microwave" with general knowledge of electromagnetism, signal generation and propagation in the microwave part of the spectrum, and  biological effects of such.  Anyway, that's the idea.

I hope it is not called Introduction to Computer Science.

So the course is something like  "Introduction to Mathematical Modeling 
in Material Science"
perhaps "... with an introduction to programming language X...".
That's fine.  There's a course at UC Berkeley in Engineering  E 7, which 
teaches simple numerical analysis,
  introduces modeling etc.   Its relation to the computer science 
curriculum tends to
evolve, partly because engineers think that their students don't need to 
know more
about computers than they do.

eh,sounds like E7 except last I heard, it didn't include symbolic 
algebra, but
made some fuss about object-oriented programming.

I think a microwave oven is indispensable too :)

I think that is justifiable, for some people.  Many mathematicians 
consider computers quite worthless
because to them, mathematics has to do with creating proofs, and 
computers (mostly) don't do this.

Some professional engineers lived their whole careers using tables in 
handbooks. Times change,
of course, but not all engineers do terribly novel things.

It is unlikely that an engineer will be called upon to write one, much 
less a collection, of
different sorting programs.  So a course on algorithms that provided 
such an experience would
seem to be, vocationally speaking, unnecessary.  Though the exercise 
might be intellectually enlightening

It is too late at night for me to figure this out, but I suspect we are 
agreeing, mostly..
