Paper: Project-based introduction to scientific computing for physics majors (Jennifer Klay)

This is the first draft of the paper for my SciPy talk.  It still needs some work.  I will finish the final draft later this week after finals are graded and exams are submitted.  Let me know if you have any questions.  Thanks!
I don't think I would consider MATLAB to be a computer algebra system (Maple and Mathematica though). If you want to include both of these I would use the phrase "interactive computing environment".
