Jmol is a Free, Open Source molecule viewer and editor. It is a collaboratively developed visualization and measurement tool for chemical scientists. Jmol is an active project, and there are new features being added to it on a daily basis. Users are encouraged to modify it to fit their needs and to contribute their changes to the project.
Omnitux aims to provide various educational activities based on multimedia elements (images, sounds, and text). Possible activity types are associations, puzzles, counting activities, etc. There is support for multiple languages and multiple screen resolutions (by using SVG vector graphic files and high quality bitmap files). Omnitux activities are described in XML files, so it is possible to create new activities without modifying the program.
OpenCards is flashcard learning software. The basic idea of OpenCards is to use PowerPoint presentations (*.ppt) as flashcard sets. Slide titles are considered questions and the slide contents their answers. Based on state-of-the-art memorization and scheduling algorithms, OpenCards will help you learn any set of flashcards.
Sugar provides a simple yet powerful means of engaging young children in the world of learning that is opened up by computers and the Internet. With Sugar, even the youngest learner will quickly become proficient in using the computer as a tool to engage in authentic problem-solving. It promotes sharing, collaborative learning, and reflection, developing skills that help children in all aspects of life.
TheCurves is an application that plots a parameterized family of curves based on algebraic formulas specified by the user. It is meant as an educational tool for mathematics, physics, and engineering. When the program is run as an applet in a Web page, the plot parameters and formulas are configurable by HTML and dynamically scriptable, so that the applet can be initialized to present a specific plot when the page is opened or to change plots when the user clicks on a control in the Web page.
X-Plane is a flight simulator that reads in the geometric shape of any aircraft and then figures out how that aircraft will fly. It does this via an engineering process called "blade element theory", which involves breaking the aircraft down into many small elements and then finding the forces on each little element many times per second. These forces are then converted into accelerations, which are then integrated to velocities and positions. This gives X-Plane the most realistic flight model available for personal computers.
