MajorTeach is a Perl script with documentation that teaches the Major System, a Mnemonics system that allows you to remember (in your brain, without additional hardware) long lists of knowledge (100 to 100,000 items long) in order, as well as long numbers, like tax ID numbers, phone numbers, credit card numbers, etc.
EZ Reusable Objects (EZRO) is a Web application that can be used by non-technical staff to manage content as "objects." Content objects containing text, video, and audio can be shared, modified, and re-styled to appear via a traditional Web site, an on-line course, an innovative "Coach," or as a community of interest site. It is highly scalable and can be used for public Web sites, secure environments, and private intra/extranets.
Pulga is a program for numerical simulation of dynamical systems. It is designed to provide a way for students and researchers who study dynamical systems to model them on a computer and analyze them numerically without the difficulty of traditional computer programming languages.
Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.
OpticalRayTracer analyzes systems of lenses. It uses optical principles and a virtual optical bench to predict the behavior of many kinds of ordinary and exotic lens types. It includes an easy-to-use interface that allows the user to rearrange the optical configuration by simply dragging lenses around using the mouse. It fully analyzes lens optical properties, including refraction and dispersion. The dispersion display uses color-coded light beams to simplify interpretation of the results.
School Admin Project is a Web-based application to provide an interface to a school's registration process. It also allows parents to log in so that they can see the performance and other details of their children online. Attendance of children and teachers can also be viewed online so that management can keep vigil on what is actually happening in the schools.
Japanese Vocabulary is an application for studying Japanese vocabulary. It consists of a set of cards, each with the kanji spelling, kana reading, and the meaning in English (or another language). It uses the Leitner system for managing the cards, which means that you see the cards you know well less often than you see the ones that you don't know very well. This allows the learner to focus on learning those words with which they are having trouble. It comes with the JLPT 2, 3, and 4 vocabulary lists.
