3 great educational apps for Linux newbies.

One of the greatest things about Linux is that there is never a shortage of applications to meet virtually every need. Below are 3 very great educational applications that most newbie Linux users will find very useful.
FlightGear
This application is a cross platform flight simulator with lots of features you might not find in other similar applications. It is an open source application that  supports standard 3D model formats. Some of the features of this application include
  • Over 20,000 real world airports included in the full scenery set.
  • Correct runway markings and placement, correct runway and approach lighting.
  • Taxiways available for many larger airports (even including the green center line lights when appropriate.)
  • Sloping runways (runways change elevation like they usually do in real life.)
  • Directional airport lighting that smoothly changes intensity as your relative view direction changes.
  • World scenery fits on 3 DVD’s. (I’m not sure that’s a feature or a problem!) But it means it has a pretty detailed coverage of the entire world.
  • Accurate terrain worldwide, based on the most recently released SRTM terrain data. 3 arc second resolution (about 90m post spacing) for North and South America, Europe, Asia, Africa, and Australia.
  • Scenery includes all vmap0 lakes, rivers, roads, railroads, cities, towns, land cover, etc.
  • Nice scenery night lighting with ground lighting concentrated in urban areas (based on real maps) and headlights visible on major highways. This allows for realistic night VFR flying with the ability to spot towns and cities and follow roads.
  • Scenery tiles are paged (loaded/unloaded) in a separate thread to minimize the frame rate hit when you need to load new areas. 
This application really has an impressive array of features that will blow you away. On Ubuntu, FlightGear can be installed via the synaptic package manager and other distro users can  download and install here.
Sakai CLE
This application, according to the site, is “[a] free and open source Courseware Management System. It features a set of software tools designed to help instructors, researchers and students collaborate online in support of their work–whether it be course instruction, research or general project collaboration.
“For coursework, Sakai provides features to supplement and enhance teaching and learning. For collaboration, Sakai has tools to help organize communication and collaborative work on campus and around the world. Using a web browser, users choose from Sakai’s tools to create a site that meets their needs. To use Sakai, no knowledge of HTML is necessary.
“But the product vision reaches beyond teaching and learning applications. Many Sakai deployments include as many or more project and research collaboration sites. In addition, the Open Source Portfolio e-Portfolio system is a core part of the Sakai software. Finally, the Sakaibrary project links library resources to Sakai.”
You can find the  download instructions of Sakai  here.
Sage
This is a free Open Source mathematics software written in python. The mission of sage is to create a viable, free and open source alternative to Magma, Maple, Mathematica and Matlab.
Sage can be used to study general and advanced, pure and applied mathematics. This includes a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, exact linear algebra and much more. It combines various software packages and seamlessly integrates their functionality into a common experience. It is well suited  for education, studying and research.  There is also a liveCD that you can directly run Sage from to get a feel of it. You can also download it for a full installation on your system.
