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."
"[It] is designed to make Mathematica as invaluable for scientific research as it is for mathematics." Cut down the advertising please. Or at least advertize some free software. It's been a while since I needes a computer algebra system. How are the free alternatives coming along? Any recommendations?
A slashvertisment suggestion for tomorrow:
"The Pirate Bay also Releases Mathematica 7"
This just seems like its got so bloated that it will likely be priced beyond the budget of most students.
I don't see why we have to have these all encompassing suites anyway, what's wrong with small tools at low cost which work together?
Its most likely that students who want but can't afford this will hit the torrent trackers, which isn't really what we want.

Much handwaving, little meat, astonishing arrogance.
Sounds more like his masturbation habits.
Maple 4 was released in April 1986. You should really consider upgrading.
Well.. maybe. Or Maybe not. But Definitely not sort of.
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.
The closest thing to a free alternative I've been able to find is Sage: http://www.sagemath.org/ Compared to MatLab, Maple, and Mathematica (yes I know MatLAB is differently purposed than the other two) the usability of Sage blows. It's pretty powerful sure, but when even Maple is easier to use then you've got a problem. I may give the new Mathematica a try. Integration with Word will make some of my lab writeups go a bit faster. Well, maybe as long as Mathematica doesn't take too long to figure out. Too bad our University doesn't sell it to students for $5 a pop anymore.
Maple 12 life!
Maxima is released under the GPL.
Octave is a free version of Matlab, practically all your Matlab code will work in Octave.

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.
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?

What do you actually mean by "easier to use", regarding a computer algebra system for doing heavy math? Clicketyclicking around without having to actually learn to use it? This easy to use mem may actually have some validity in desktop environments and generall consumer leisure apps, but I'm wondering to actually see such unwillingness to learn from people doing _MATH_, which are, by definition, required to be curious into how things work and not just clicking around and rotating colorful 3D surfaces the whole day.
Mathematica 7 is so powerful, Linux runs on it
try { do() || do_not(); } catch (JediException err) { yoda(err); }
does it matter that it's open source or not?
It does if you don't have $2400 to spend on a copy of Mathematica.
"Not an actor, but he plays one on TV."
I have found one problem with open source toolchans - producing good quality graphics. At the end of the day you have to present the data, and gnuplot just isn't cutting it anymore.
I've used Maple, Mathematica, and SAS, among other products, for mathematical and/or statistical analysis. From a programming/features perspective, each has its own strengths--and weaknesses.
I'll only briefly mention cost. These things are expensive because it's not like any random programmer can build this kind of software. Especially with Mathematica, these are heavily-researched algorithms that are nontrivial to implement. Also, the market is small for such a specialized and sophisticated application. Your average person isn't ever going to be able to use something like this. They barely know what the quadratic formula is. (They should, but that's an entirely different story.) You think they need to invert a 20x20 matrix? Or compute the Galois group of a quintic? Or even do a simple hypothesis test?
As for the image manipulation stuff, I think that comparisons to Photoshop are a bit naive. Clearly, it's not supposed to be for people who want to do red-eye reduction on their family photos. It's not even for graphic designers or photographers. It's for scientists who want an algorithmic approach to adjusting their images, either for research or for purposes of publication. Could you do these things in Photoshop? Sure. Could you then say what formula or algorithm was applied to the image to produce that specific result? No. And conversely, you wouldn't do layer composition, masking, or on-the-fly tonal adjustments with Mathematica.
FWIW I hate the copy protection on it too. It's infuriating and a burden to legitimate users while doing little to deter piracy.
Uhh...

Since this is a list of "New Features", previous versions of Mathematica could not be used for these purposes. All you could do was show a fellow math geek how that humanities major had a really nice set of 80085.
> Unification of Graphics, Text & Controls
In previous versions, you were lucky if what you wrote or clicked resembled anything like the output! Now, when when you type in "y=x", you actually get a straight diagonal line, instead of one of the spirally partial differential functions we like to put on the cover of the manual!
> Language for Data Integration
There's now its own scripting language. Whoa, Mathematica never had *that* before!
> Dynamic Graphical Input
Use symbols you never thought possible! Like that squiggly "integrate" symbol, or that lambda derive-like thingy. Even use that upside-down "U" for set theory!
> Instant Multimedia Programming
Uses both Video and Audio! Include a Youtube video in your equations of Stephen himself telling you how wrong your equation is!
> Real-Time Code Annotation
Add "comments" whenever and wherever you want! No other language has the ability to "comment" on your code!
> Instant High-Level Debugging
Be able to step through your code and set break points! Stephen is the first person to think of it! No other programming IDE has ever done anything so revolutionary!
> Integrated Graphics Editing & Drawing
Did your equations predict that the Mars Lander was going to crash and burn? Use the Graph Editor to change the equation output, and show your fellow engineers a perfect atmospheric re-entry! Then re-sell those high-risk equations to an over-leveraged engineer who does care! You'll be long gone by the time they realize what you've done! This feature brought to you by the Lenders Association of US Banks.
> HID Support
You may now use a mouse and keyboard in this version, instead of simply shouting at the screen, hoping it'll do something!
> Streamlined Presentation Framework
Use an overhead projector instead of a video monitor to show your results!
> New Documentation Framework Dynamic Interactivity
We'd like to call it "Google"...
