  • The Harmony of the World Icon

    The Harmony of the World

    A fair attempt at the Keplerian tradition to explore the solar system

    Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. Features:audio, database, graphics Technologies: Telnet, .WAV audio, oggvorbis, other audio

  • Celestial Precomputation Icon

    Celestial Precomputation

    Sight Reduction for Air Navigation with Python

    This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!

  • MoonPlanner Icon


    Moon calendar: shows moon's phase, signs and relatives plant's part

    MoonPlanner is a Java calendar that allow to view moon's phases, moon's signs (constellations in which the moon is), and show the part of the plant corresponding to each sign (flower, fruit, leaf or root). For every calendar's day the user can attach notes (that are stored in a persistent database). At the startup the program will remind you if there will be notes for current day. Timezones and localizations (En, IT) are supported by the application. This calendar is usable between 1900 and 2020. This tool can be useful to plan gardening tasks or to view some astrology informations. References and requirements: - JRE/JDK version 1.5 or later must be installed on host computer. - UI are made using SWT by Eclipse (see - The software uses AstroLib library version 1.1.5 provided by Mark Huss to calculate Moon's phases ( - The software uses Apache Derby ( as embedded database.
