Wolfram Research Releases Mathematica 7 234
mblase writes "Wolfram Research has released the seventh version of Mathematica, and it does a lot more than symbolic algebra. New features range from things as simple as cut-and-paste integration with Microsoft Word's Equation Editor to instant 3D models of mathematical objects to the most expensive clone of Photoshop ever. Full suites of genome, chemical, weather, astronomical, financial, and geodesic data (or support for same) is designed to make Mathematica as invaluable for scientific research as it is for mathematics."

Much handwaving, little meat, astonishing arrogance.
One of the most overhyped books I've ever actually been suckered into buying.
I found particularly offputting W's treatment of important parts of his own thesis (computational completeness of some automata) as commercial secrets

Wolfram does not want you to work with any competitor's product. He wants you to raise a mortgage in order to be able to pay for his "complete solution".

Except it really is what most of us want. Why shouldn't it?
Fuck Mathematica (Score:4, Informative)
and fuck Matlab too, while we are at it. I got a free hit of Matlab in university and then found out how much they charge for licenses only after I was an addict (had a pile of useful code that I didn't want to throw away). I am not going to keep paying for the privilege of running my own code and am busily learning Python.
Mathematica code belongs to Wolfram Research, Matlab code belongs to the Mathworks, but Python code can be MINE! (and yours too, if I want to give it to you.)
I don't buy into the virtual machines they are pushing now either; they might be free as in beer, but it is only a short-term solution and is nothing more than "free hits" to generate more addicts that need licenses.

You mean, as amazing as the amount of skill and know how required for practically every large scale application?

You can any time start looking at and learning from completely free systems like GNU Octave, Sage or SciLab.

You don't have to throw that code away or port it to an entirely different language (though Python rocks, and I wish my day-to-day job let me use more of it) Try GNU Octave [gnu.org] - that's what I used to back in college because my department didn't have licensed copies of MATLAB installed/available, so-called student versions were insanely impossible and expensive to get hold of (Indian students can't afford $100), and I didn't want to pick a pirated one like the rest of the class.
Possible the first open-spurce software I practically used (except playing with Linux).
Code was very cross-compatible between Octave and MATLAB, except say constants like "e" and "exp" (and of course the MATLAB-specific toolkits). The toughest part at that time was explaining to the professor (who had no idea what "open-source" was) that I did *not* use MATLAB, but it would run on MATLAB fine if he wanted to check that my assignments work fine.
API sucks (Score:5, Informative)
I had to write some code using the Mathematica API once, and it hurt. It provides a pipe of tokens, but if you ask for the wrong token, it hangs. You can peak at the front of the queue, but it's still the case that every time you want to read in a token you have to write code to expect any of a million different types of token for all the crazy error messages you never knew you might get.
Also, the GUI is awful. That notebook metaphor just does not work. You want to remove a buggy line of code somewhere but it might be attached to another block so it's really hard to get hold of it. The navigation keys (pg up, end and so on) don't work as you'd expect in an editor so you become very mouse reliant, which is awful for anybody used to working in a programming environment.
In my experience, Matlab is far superior although as others have pointed out, I'd still rather be working in Python. Numpy anybody?

No advertising here, just a happy math nerd who was recently investigating alternatives like Maxima and SciLab himself recently, and was impressed that the new version of Mathematica leapfrogged them all by doing much more instead of just doing what it does faster.
(This despite the fact that Mathematica is, and nearly always has been, far more number-crunching power than I've ever needed in my academic or professional career.)

It does if you don't have $2400 to spend on a copy of Mathematica.

Mathematica is truly one of the most impressive programs I have used. (Unlike other large scale programs like Office, Matlab, Labview, etc, it contains a lot of code that I just wouldn't know how to even start rewriting if I had to....stuff like Solve[] or Integrate[])
That being said, Mathematica 6 really annoyed me. They completely changed the way MultipleListPlot[] works, which broke a lot of my older notebooks. (The old way was not very good, but backwards compatibility is crucial.)
Re:Maxima (Score:1, Informative)
This is a development version of Maxima. The function bug_report() provides bug reporting information.
Yeah, I know, it's not a real excuse - they probably could do with some improvements to their automated pre-release testing, even for development versions.
But then, it IS a development version, not a stable one, so things like this aren't entirely unexpected, either. And you really shouldn't use development versions for production, anyway: you actually got lucky that you just got a segfault. It might just as well have been the wrong result, without any indication that anything went wrong.

Octave is a great program (I switched from MATLAB too, after my bought-and-paid-for copy of MATLAB was broken by a simple OS X upgrade). But Octave is not a symbolic computer algebra system like Mathematica, Maple, Maxima, etc., so it cannot properly be called a Mathematica alternative.
