I've been a professor of mathematics at The University of North Carolina - Asheville since 1997. I've been using Mathematica since I started graduate school in mathematics at Ohio State in 1989. At that time, we used version 1.1 (as I recall) to teach calculus in our Calculus and Mathematica classes. I've used it pretty much continuously in my teaching and research since then.

In addition to my posts on SE, you can find some of my papers, teaching notebooks and other Mathematica based oddities strewn throughout my website.

In recent years, I've also worked as a part-time consultant to Wolfram Research focusing on development of mathematical content for WolframAlpha.

comment Module function corrupts string?
+1 @TraceKira This code is much more idiomatic and easily readable by anyone who is familiar with Mathematica. This style of programming is also much more efficient in Mathematica, as I've tried to illustrate in my edit.

@B.Lee An accept is ample and you're welcome. Maybe Beli could bounty it, as he has 64K these days. :)

comment Graphs Plotting Discontinuous
Much faster, in fact! I actually considered that but didn't try it as I figured it would be very slow as Eigenvalues is evaluated with each and every step. Evidently, the list Root objects take longer to evaluate than Eigenvalues, which might very well be evaluated numerically in this context. Looks worth a +1!

comment Graphs Plotting Discontinuous
But now, all the plots are the same color. Worse, the standard tricks involving Evaluate, With, or the Evaluated option all bring the discontinuities back, as Chop applied to non-numeric expressions just returns the expressions. I was only able to resolve this by generating the data and using ListPlot.
