Wolfram Research Releases Mathematica 7

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."

      does it matter that it's open source or not? Open source is not inherently better than closed source.

      Being able to show exactly which steps a CAS went through to arrive at a solution can be important. With Mathematica, you have to trust that the methods they use, which you can't see, are legitimate and don't introduce any unforeseen error.
      I don't mean to pooh-pooh Mathematica; it's an excellent program. But being able to show 100% of your work has intrinsic value.

      And you can use Mathematica, Matlab, Maple, Magma, Maxima, etc from inside Sage if you have those programs available.

      Absolutely.

      I work on pretty much a daily basis with computer algebra systems. In my work, I am using CAS systems to perform integrals on what would be otherwise an unmanageable amount of equations, in order to generate some nice neat, but still quite large matrices. Despite its obvious technical inferiority, I'm using Maxima to do this. A lot of this has to do with running Mathematica and the like on Linux, which is a painful process, but the peer reviewable nature of an open source system is another major factor.

      I've said this before, but essentially Mathematica is the modern mathematical Oracle at Delphi; arcane, totally inscrutable, and regarded by almost everyone as infallible. You cannot use its results professional for anything other than integral tables or the like. At least, not in mathematics. Maybe physicists use it, but I'd have my doubts. (Engineers? ... well they're a heathen lot anyway...)

      True, Mathematica is useful. But it's closed source nature, combined with its almost universal presence in scientific research is very troubling.

    The student version is cheap (free at most decent universities). The Wolfram folk are great if you need a deviation on the license for student stuff (running on a multi-processor machine before multiple kernel executions were included in the default license); just ask. As a long-time student, Mathematica is the greatest tool out there, and is the only software out there where I'm consistently excited about no versions, and /always/ find ways to incorporate at least a few of the new features in my existing notebooks. With Mathematica 6, Manipulate[] was an absolute game changer. With Mathematica 7, I'm betting ParallelTable[] and the new charting features will be just as big a deal, for me.

    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 - 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.
