    The Harmony of the World

    The Harmony of the World

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

    ...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. ...

    Set Theory Relations in Java

    Java classes implementing set theory relation concepts

    Simple java classes implementing basic concepts of relations as defined in set theory. A relation is a set of ordered pairs. A relation can have properties, including that it is reflexive, symmetric, or transitive. The classes enable some ordered pairs to be stated, and will deduce all the other related ordered pairs implied by the relation's properties. There are implementations of transitive, reflexive-and-transitive, and symmetric-reflexive-and-transitive (equivalence) relations using...
