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.

This should probably do it.

You should certainly indicate what version and OS you're working with for this type of question. The code works fine for me in version 9.0.0 on Mac OSX 10.7.4.

comment Handling Overflow
It would be nice to have more details about what you are doing. If you're iterating a polynomial, for example, there's a simple bound on the absolute value of the iterate, beyond which, you are guaranteed the orbit will diverge to Infinity. It's easy to incorporate this into a loop or a NestWhileList. One issue with Check is that the Overflow[] won't be detected until after it happens. That's way too late, if you're working with compiled code.

comment How to scrape the headlines from New York Times and Wall Street Journal?
@RodLm Yes, that is pretty awesome, isn't it. Mathematica's import/export is generally outstanding in two ways - the broad range of filetypes it works with and the way it consistently represents things in it's own language. You might also be interested in this question, which deals with importing HTML as XML.
