*"Wolfram Research has just released Mathematica 6. That link, in addition to the usual 'dramatic breakthrough' material, has an amazing flash banner that simultaneously shows a thousand mathematical demonstrations all at once. The animations came from the Wolfram Demonstrations Project, a free service with 1200+ dynamically interactive examples of math, science, and physics, all with code. For the product itself, much is new or improved, with built-in math databases, improved visualizations, and more."*

However, I recently ran into one of those "top 10 reasons why proprietary software is annoying" situations. I hadn't used Mathematica in awhile, and wanted to go back to some old code and re-run some analysis. However in the meantime I had migrated from Windows to Linux. No problem--the install disk has the installer for Windows, Linux, and Mac all in one. Great. So I install it in Linux and then get the annoying "you must register this product to use it." (On Windows it gives you two weeks before locking out, but in Linux it won't open unless you enter the code, which changes with each new hardware installation.) The online automatic registration said I had to contact them via email. So I did. Eventually got the reactivation code. Turns out it didn't run properly on Linux. The controls were clunky and I couldn't get individuals block to execute (though I could re-execute an entire workbook.) Okay, no problem--I have a Mac laptop. So I load it up there. Then I have to go through the reactivation process again. Another email, more waiting. Eventually get it running.

My point is that I had alot of difficulty getting my (legitimately purchased) copy of Mathematica to actually work for me. I was in a hurry and just wanted to run some code quickly. This 10-minute operation turned into a 4-day ordeal, at the end of which I was very frustrated. It really reminded me the great advantages of programming in standards-based languages, that have open-source implementations. If the code had been written in python (using the Gnu Scientific Library), I would have been able to run it without hassles, and I could send the code to others, knowing that installing Python (on the OS of their choice) was always easy.

I don't want to turn this into a stereotypical OSS vs. proprietary rant... but this very recent experience with Mathematica has left a bad taste in my mouth--and I was previously very much a Mathematica evangelist!

I do science in the real world. I can safely say that's a patently ridiculous assertion. We rely on any software we can get to work. Often that's commercial software, because people who develop good software in science frequently take it commercial.

It's our results that need to be replicated, not our methods. Anyone can do the same thing and get the same result. Doing it by a different method and getting the same result is a much more rigorous validation. As long as it's a different box, it doesn't matter if one or both are black.

It's also to our benefit to use commercial software because it's cheaper to buy it, including (re)licensing fees and support, because it's cheaper than paying salary to a code hacker to keep things running. Maybe some have the spare time to hack their own code. I wish I did. But I've got more important things to do.

I've worked in a lab that at first had a EE doctoral student doing Matlab code, and then started using some hardware that required doing analysis in Code Warrior. We needed to get someone else. Not good for the first guy, and expensive in either case for us. I also started collaborating with a lab that used the only open source analysis software in our field (only one other lab used it; the one the lab director came from). I could do by myself what took them 3 people to do, and get it done faster. The collaboration didn't last long.

The accepted procedure in carrying out and publishing research is to reference the software manufacturers in the text and/or references section. If anyone wants to check the results by getting the same things and doing the samr things with them to check validity, they're welcome to. But they don't. They use what they have and compare results. If they really want to check the validity of results, they can get copies of the validity testing done on the software. Any decent software maker will have already done all the validity testing necessary and is glad to make that data available.

Mathematica has a killer engine (kernel), but a lousy UI, and it costs a shocking amount of money. Mathematica was one of the first pieces of software to scan your computer's MAC address and serial number while you entered the activation key, so it could not be installed on more than one computer (this after the $250-$1000 price tag). A student can get the castrated $250 version, but the real version is considerably pricier. Wolfram's treatment of his users is as distrustful as Micro-Suck.

Why can't the FOSS community beat Wolfram at this? Octave, Maxima, Yacas; they all fail miserably in comparison. The UI for Yacas is so idiotic that the function that transposes a matrix is

Transpose[], anine-characterentry for an operation that a real mathematician may use a few hundred times in a given program. At least Mathematica is smart enough to useT(or at least it was when I last used it, at 4.0). Why can't we do better than this?The best UI of any CAS was the UI for the built-in graphing calculator for Mac OS 9. The current version, NuCalc, is available for Mac and Windows, but it is proprietary, and there is no plan for a Linux/UNIX version. The FOSS community can put a UI like NuCalc over a Maxima engine, use MathML and/or LaTeX for the syntax (like LaTeX input, MathML output). Use code from GNU TeXmacs for the UI, but include the beautiful way that NuCalc simplifies fractions and radicals (and algebraic equations) by clicking on them with the mouse. Brilliant. And possible. Future generations of math and physics and engineering grad students will thank us.

They won't have the glitzy graphics or army of specialized packages Mathematica boasts, but they also don't cost $1500 and (theoretically) can be audited for correctness all the way down to their foundations. I regard the latter as very important for people trying to do scientific research with computer algebra tools, and what's more no commercial company is required for their survival (the story of Macsyma is a very good object lesson.)

Maxima is the more "engineering" oriented of the two systems and will probably make more sense to Mathematica inclined users - it can use gnuplot, run on Windows and has a decent GUI called wxMaxima: http://wxmaxima.sf.net./ [wxmaxima.sf.net] Axiom is more oriented towards being "strong" mathematically - it takes more getting used to and has very ambitious goals for long term mathematical research. It is attempting to become a literate program in the tradition of Knuth's TeX system. It doesn't currently have the interfaces to familiar tools the way Maxima does.

Both systems are already very powerful and while there are many bugs to work out progress is being made. If you're shopping around for a CAS and are interested in open source systems, I highly recommend checking them out.
