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.

You can also do h[u_] = pol1^2 - pol2^2 /. x -> u in your definition of h, i.e. Set, rather than SetDelayed.

comment Simple derivative not working
Glad it helped! Markdown in comments is somewhat different than markdown in a post, I believe.

comment Problem With NDsolve trying to simulate n-body-gravity problem
You might be interested in this notebook, which contains code to deal with a fairly large number of objects specified in {mass,pos,vel} form. When two objects collide, however, a singularity arises and you simply cannot expect to integrate past that point. You can use InterpolatingFunctionDomain to deal with it gracefully but that's about it.

comment Solution given by Wolfram Alpha but not _Mathematica_
The WolframAlpha result can be produced with Reduce[Log[x] == Log[j, Log[j, x]], j, Reals]. In general, you should not assume that Mathematica commands typed into WolframAlpha will be executed verbatim on the server side.
