    The Harmony of the World

    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...

    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...
