Polar Diagrams We now come to the circular or polar representations of the “P” (not to be confused with “polarity” as a value-form). Here there are three different elementary possibilities: 1) the simple circular form of the “P”, in which the right- or oblique-angled coordinate grid is converted into polar coordinates; 2) the division of the circle (either of the circumference or the angle at the center) according to the measure of the partial-tone ratios; and 3) the transformation of these ratios, i.e. the “P”, into vectors (angles), while simultaneously notating them as distances from the center or the generator-tone circle.

Figure of the heavenly bodies — An illustration of the Ptolemaic geocentric system by Portuguese cosmographer and cartographer Bartolomeu Velho, 1568 (Bibliothèque Nationale, Paris) In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system) is a description of the cosmos where Earth is at the orbital center of all celestial bodies.

Geocentric model

This model served as the predominant cosmological system in many ancient civilizations such as ancient Greece including the noteworthy systems of Aristotle (see Aristotelian physics) and Ptolemy. As such, they assumed that the Sun, Moon, stars, and naked eye planets circled Earth.[1] Two commonly made observations supported the idea that Earth was the center of the Universe. The first observation was that the stars, the sun, and planets appear to revolve around Earth each day, making Earth the center of that system. Heliocentrism.

Heliocentrism

Heliocentrism, or heliocentricism,[1] is the astronomical model in which the Earth and planets revolve around a relatively stationary Sun at the center of the Solar System. The word comes from the Greek (ἥλιος helios "sun" and κέντρον kentron "center"). Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center.

The notion that the Earth revolves around the Sun had been proposed as early as the 3rd century BC by Aristarchus of Samos,[2] but at least in the post-Ancient world Aristarchus's heliocentrism attracted little attention – possibly because of the loss of scientific works of the Hellenistic Era[3] – until Copernicus revived and elaborated it.[4] House (astrology) Most horoscopic traditions of astrology systems divide the horoscope into a number (usually twelve) of houses whose positions depend on time and location rather than on date.

House (astrology)

In Hindu astrological tradition these are known as Bhāvas. The houses of the horoscope represent different spheres of life, described in terms of physical surroundings as well as personal life experiences. This 18th-century Icelandic manuscript drawing shows the twelve astrological houses with signs for the planetary rulership or maybe planetary joy. The houses are divisions of the ecliptic plane (a great circle containing the Sun's orbit as seen from the earth), at the time and place of the horoscope in question. They are numbered counter-clockwise from the cusp of the first house.

Discovery and exploration Andreas Cellarius's illustration of the Copernican system, from the Harmonia Macrocosmica (1660) For many thousands of years, humanity, with a few notable exceptions, did not recognize the existence of the Solar System.

Solar System

People believed Earth to be stationary at the centre of the universe and categorically different from the divine or ethereal objects that moved through the sky. Although the Greek philosopher Aristarchus of Samos had speculated on a heliocentric reordering of the cosmos,[11] Nicolaus Copernicus was the first to develop a mathematically predictive heliocentric system.[12] His 17th-century successors, Galileo Galilei, Johannes Kepler and Isaac Newton, developed an understanding of physics that led to the gradual acceptance of the idea that Earth moves around the Sun and that the planets are governed by the same physical laws that governed Earth.

Astrology. People who study Astrology are called an astrologer, astrologist or a mathematicus.

Astrology

Astrology is considered as a form of divination and is different from the study of astronomy. The word Astrology stems from the Greek. The belief in astrology is that the positions of certain celestial bodies either influence or correlate with a persons personality trait.
