SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility. SciDAVis runs on GNU/Linux, Windows and MacOS X; possibly also on other platforms like *BSD, although this is untested.SciDAVis is similar in its field of application to proprietary Windows applications like Origin and SigmaPlot as well as free applications like QtiPlot, Labplot and Gnuplot.What sets SciDAVis apart from the above is its emphasis on providing a friendly and open environment (in the software as well as the project) for new and experienced users alike. Particularly, this means that we will try to provide good documentation on all levels, ranging from user’s manual over tutorials down to and including documentation of the internal APIs We encourage users to share their experiences on our forums and on our mailing lists.More information, including screenshots, reviews, current contributors can be found on the SourceForge project webpage.

Advertisement: This package contains only TexLive, a spell checker (Hunspell) and a version control. Via addons you can add support for LilyPond, Sweave and Knitr. After installation you must reconfigure, Tools-&gt;ReconfigureLyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. A broad array of ready, well-designed document layouts are built in.LyX is for people who want their writing to look great, right out of the box. No more endless tinkering with formatting details, “finger painting” font attributes or futzing around with page boundaries. You just write. On screen, LyX looks like any word processor; its printed output — or richly cross-referenced PDF, just as readily produced — looks like nothing else.

KAlgebra is an application that can replace your graphing calculator. It has numerical, logical, symbolic, and analysis features that let you calculate mathematical expressions on the console and graphically plot the results in 2D or 3D. KAlgebra is rooted in the Mathematical Markup Language (MathML); however, one does not need to know MathML to use KAlgebra.

      wxMaxima is a graphical user interface for the computer algebra system Maxima:
      a program that solves mathematical problems by manipulating
      equations (and outputting the resulting formula), instead of just
      calculating a number. wxMaxima eases the use of Maxima by making
      most of its commands available through a menu system and by
      providing input dialogs for commands that require more than one
      argument. It also implements its own display engine that outputs
      mathematical symbols directly instead of depicting them with
      ASCII characters.
    
      
      wxMaxima also features 2D and 3D inline plots, simple animations,
      mixing of text and mathematical calculations to create documents,
      exporting of input and output to TeX, document structuring and a
      browser for Maxima's manual including command index and full text
      searching.

Genius is a general purpose calculator program similar in some aspects to BC, Matlab, Maple or Mathematica. It is useful both as a simple calculator and as a research or educational tool. The syntax is very intuitive and is designed to mimic how mathematics is usually written. GEL is the name of its extension language, it stands for Genius Extension Language, clever isn't it? In fact, many of the standard genius functions are written in GEL itself.What can it do?Arbitrary precision integers, multiple precision floats.Complex numbers, stored in Cartesian coordinates as usual.Math-like-looking expressions, tries to be as much a what-you-mean-is-what-Genius-understands, up to a limit of course.Matrix calculations / Linear Algebra, with many related functions.Number theory.Calculus, numerical and even very limited symbolic calculations.Statistics, all the basic statistical functions.Numerical equation solving, polynomial roots, etc...Combinatorics.Most common elementary / trigonometric functions.Modular arithmetic, including inversions and modular arithmetic on matrices.A complete programming language, with automatic typing. In fact large part of Genius standard library is written in GEL.2D Function line plots, standard 2D graphs of up to 10 functions at once, with possibility to export to EPS or PNG.Parametric plots, with possibility to export to EPS or PNG.3D Function surface plots, with possibility to export to EPS or PNGSlopefield/Vectorfield plotting.GUI IDE where you can edit and run/test your programs.Can output matrices in LaTeX, Troff (eqn) or MathML, this is I think a very cool feature that allows you to copy stuff directly from Genius to a document in LaTeX, troff or MathML.

Blinken is based on an electronic game released in 1978, which challenges players to remember sequences of increasing length. On the face of the device, there are 4 different color buttons, each one with their own distinctive sound. These buttons light up randomly, creating the sequence that the player must then recall. If the player is successful in remembering the sequence of lights in the correct order, they advance to the next stage, where an identical sequence with one extra step is presented. If they are incorrect, the game is lost, and the player must start again from the beginning. The goal is to get a high score - each step in the sequence is worth one point, so correct entry of a sequence of 8 lights is worth 8 points on the high score table.

Denemo is a music notation program that lets you rapidly enter notation. Music can be typed in at the PC-Keyboard, or played in via MIDI controller. The typesetting is done in the background by LilyPond while you work, and is generally flawless publication quality. Any final tweaks to can be done on the final typeset score with the mouse if needed. This represents an enormous practical improvement over the most programs which require you to re-position colliding notation constantly as you enter the music.Unique to Denemo are methods to enter music in a musical, rather than mechanical, manner. You play in a phrase or two of the music using the number keys to indicate the note durations. Audible feedback lets you hear what you have entered; playing the phrase a second time on a real instrument adds the pitches to the rhythm. Again, Denemo gives you audible feedback so that you don’t enter E-flat when you meant D-sharp etc.Another great feature is the ability to put links in the score to the original source document that you transcribed from. Clicking on such a link opens the document for you and highlights the bar you are looking at. You can use this to continue work from where you left off, or for looking back at the source to check a doubtful bar.
