Eratosthenes

In 1993, Jacques Dutka shared information about the Greek mathematician Eratosthenes, reportedly nicknamed “’New Plato’” (Fisher, 1982, p. 803).  Dutka said, “About 230 B.C., Eratosthenes of Cyrene (275-194 B.C.) made a measurement of the circumference of the Earth, assumed spherical in form” (Dutka, 1993, p. 55). Dutka goes on and describes that “His method was based on a remarkably simple proportion relating the difference between the latitudes of two stations on the same meridian, obtained from celestial observations, and their terrestrial distance apart” (Dutka p. 55). Having said that, Eratosthenes had a career. Specifically, Kelly Trumble mentioned that Eratosthenes, held the prestigious job of Librarian at the Library of Alexandria (Trumble, 2003 p. 24).

Centuries after Eratosthenes lived, the Apostle Paul said, “He was delivered over to death for our sins and was raised to life for our justification” (NIV, Rom 4:25). God does not remember the sins of the justified, though man records history for His or man’s purposes. With that in mind, the library’s total contents have been under contention. Roger S. Bagnall shared the state of research in the year 2002. Bagnall said, “Moreover, if we are to give any credence to these numbers, why should we not be consistent in our credulity and believe that Demetrios of Phaleron already had amassed 200,000 volumes in the first decade of the third century B.C. as Pseudo-Aristeas says” (Bagnall, 2002, p.). According to Daniel Heller-Roazen, the Library of Alexandria may have burned down in “the fourth century” (Heller-Roazen, 2002, p. 149) BC.

With growing interest in astronomy and the mathematical sciences as a computer science major, my extracurricular activities are increasingly involving observance of the heavens and sacred spheres of thought. During this experience, the more technology improves, the more I seek fundamental understanding.

Coordinate Systems: Inputs and Outputs

With the various coordinate systems involved in mathematical deduction such as Cartesian, Polar, Cylindrical, and Spherical, the correctness of system application depends on the applicability of human work utilizing any or all of them for morally good results. For example, when building a house, a Psalm begins with the truth that says, “Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain” (Ps 127:1). Therefore, Rene Descartes’ famous statement may be analyzed. Descartes said: “cogito ergo sum: I think therefore I am” (Web 1). In saying this, the inventor of the Cartesian coordinate system was asserting that his mind gives him substance. I believe that more accurate is mihi virtutem Dei ergo sum: God gives me strength therefore I am. This is supported by the Biblical Scriptures. The anonymous writer (KJV) of the Book of Hebrews wrote, “For every house is builded by some man; but he that built all things is God” (3:4). The first act that the Most High did, creation, was viewed by Him as good (Ge 1:31). In following His eternally supreme standard, I think that choosing a coordinate system is therefore supported by a truly good purpose for utilizing it. Examples are Cartesian for building a contemporary rectangular home for the homeless (Pro 21:13), Cylindrical for a ship required for national defense and protecting marginalized groups (Ex 22:21-23), and Spherical for determining the shortest distance between two points on the ocean with longitude known so that demanded food suppliers perform their obligations in their appointed time (Ecc 3:1-8).
