Paper: Scientific Computing with SciPy for Undergraduate Physics Majors (Bill Baxter)

Paper for SciPy2014 proceedings.  I'm a GitHub and rst novice so this should be interesting!  I'm having two issues: first, I don't see how to get my figure file onto GitHub.  Second, I'm clearly doing the reference labels for tables and figures incorrectly.  Hopefully someone can point me in the right direction!
That is a concern.  There are going to be instances where lack of understanding leads to confusion.  One place this happens is in fitting.  If the initial choice of parameters is too far wrong, then the fit never converges and students wonder why?   Fitting becomes a 'black art'.  If you look at my resources which I am in the process of putting online, I don't completely ignore the numerical process though I don't make the technique the emphasis.  I figure students have to start somewhere.  So why not learn some useful tools before you dig deeply into the technique.
