The Wikipedia list is very long. For anyone who's specifically interested in OSS that runs on Linux, here are some of my impressions:

Maxima- In my experience, it's very mature and bug-free. It's only suitable for interactice use; e.g., if you do certain integrals, it will ask you whether a particular constant occurring in the integrand is positive.Yacas- Unlike Maxima, is designed to be suitable for both interactive and noninteractive use. Somewhat buggy, and fails more often than Maxima does.Axiom- Has a complete implementation of the Risch algorithm [wikipedia.org], so it can do some integrals that other programs can't. E.g., it can integrate 1/(x^4-8*x^3+8*x^2-8*x+7), and so can Maxima, but Yacas can't.Sage- Pros: Sage lets you program in python, so if you want to mix in some general-purpose programming, python libraries, etc., you can. Sage implements arbitrary-precision arithmetic much more efficiently than programs that use the GMP library. (E.g., sage computes (2^123456789-1)%(2^12345678-1) in about 10 s, whereas ordinary python takes longer to evaluate (2**123456789-1)%(2**12345678-1) than I was willing to wait.) Cons: It's basically a hairball of other math packages, and the interface to other packages often doesn't seem to be very good. It's not packaged properly for debian/ubuntu. The tutorial shows you how to do lots of fancy things using examples from abstract algebra, but doesn't tell you ordinary, useful things, like how to integrate x^a.## Re: (Score:2, Insightful)

As much as Adobe would like to sell it as the tool for EVERY purpose under the sun - Photoshop is not really aimed at mathematical/scientific image processing. It was originally aimed at pre-press as a complement to PostScript and Illustrator, and later diversified to web production, etc.

Photoshop has a severe case of feature creep - resulting in a product that, instead of doing one thing well (it always was the leader in print production), does too many things less well.

> High-Impact Adaptive Visualization

It's got graphics now.

> Automated Computational Aesthetics

You don't have to graph things out by hand.

> Fully Automated Graph Layout

You don't have to graph things out by hand.

> Real-Time 3D Graphics

If you change your equation, the graph changes too.

> Automated Table Layout

Shows you the points they graphed.

> Dynamic Interactivity

It's got a GUI.

> Integrated Geometric Computing

Runs on a computer following Moore's law, hence "geometric" advancement.

> Combinatorial Optimization

Solve the Travelling Salesman problem by something other than brute force.

> Equational Theorem Proving

Okay, that could be cool... if the previous versions didn't have it already.

It can use numbers now?

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"...

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 certainly don't know what it takes to program a scientific program. It's not your "usual" large-scale application. It's far more involved than you think it is. You cannot simply have some mad programming skills to make it. You also need to have some mad math skills to make some REAL optimizations.
