Starchart There is a sky. There are things in the sky. This program draws maps of things in the sky. The things in the sky include stars, planets, nebulae, clusters of stars, and galaxies. For thousands of years, people have grouped the stars in the sky into patterns, and constellations. More recently, the sky has been divided into areas based on these constellations. For hundreds of years, astronomers have used a latitude-longitude grid for defining the locations of
celestial objects. The longitude is usually referred to as right ascension or RA, the latitude is the declination or DEC. Through the year, the sun follows a path in the sky, called the Ecliptic, which is the plane of the earth's orbit. Other planets in the solar system are roughly in this plane. This program displays all these elements on various display and printer devices. The locations of stars, nebulae, clusters, and galaxies have been tabulated for hundreds of years. This program uses computerized forms of such databases.

Stars may be viewed (or ignored) by spectral class and absolute magnitude. Other features include support for both celestial and galactic coordinate systems, the ability to display extended non-stellar objects, and a pop-up Hertzsprung-Russell diagram. StarPlot is also packaged with starconvert, a utility which converts line-oriented stellar data records to StarPlot format. Most star data files available on the Internet can be converted this way if a short file describing the original file format is provided to starconvert.

Tkgeomap is a set of extensions to Tcl/Tk for displaying and interacting with geographic data...Tkgeomap is not a full featured geographical information system. For example, calculations assume the Earth is a sphere, and data is stored in internal data structures at single precision, giving a resolution of about 10 meters. This is good enough for my work (meteorology). If you need more accuracy, you should probably use a GIS, such as GRASS. All of the data in Tkgeomap is vectorized, which is to say information is stored in arrays and tables of latitudes and longitudes. It does not display or manipulate rasterized images. Hopefully, Tkgeomap will provide others with useful geographic data access and insight with minimal spin up time.

VPython Package for simple 3D programing in Python 2.2
From the VPython web page:
While a sophomore in computer science at Carnegie Mellon University,
David Scherer created a 3D graphics module for Python, called
"Visual," that is exceptionally easy to use. A program can create 3D
objects (such as spheres, curves, etc.) and position them in 3D space.
Visual, running in a separate thread, automatically updates a 3D scene
many times per second, to reflect the current positions of the
objects. The programmer does not need to deal with display management,
but can focus on the computational aspects of the program. The user
can navigate in the 3D scene by using the mouse to zoom and rotate
while the program is running. Visual supports full vector algebra. (Generic Open Source)

Because the Montessori bells are a lovely and extremely expensive piece of equipment to buy, we have made a software equivalent of the first few activities usually done with the bells. We suggest that parents and teachers present and supervise the activities as they would the real bells. We think it will be worthwhile for adults to spend a bit of time familiarising themselves with our bells themselves before presenting them to a child, in order to avoid frustrating the child with any confusion. We suggest that the bells be introduced at a stage when the child is showing interest in music or singing.
