model can be used at the top level of the hierarchy. Within each level, blocks can contain foreign domains. Ptolemy uses the object-oriented principles of polymorphism and information hiding to achieve modular interoperability. This hierarchical heterogeneity is quite different from the simulation ...
Ptolemy advanced the geocentric model of our solar system (alternatively termed the Ptolemaic model) which, along with most of his other theories, influenced scientific thought in this field until the Copernican revolution. The widespread speculations among his contemporaries (the most famous being the...
Until the appearance of Copernicus’ De revolutionibus orbium coelestium (On the Revolutions of Heavenly Spheres), the Almagest remained the unsurpassed model exposition of the whole of astronomical knowledge. It was of exceptional practical importance for navigation and the determination of geographic ...
His Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres,[23] in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an avera...
Before the invention of a telescope, Tycho Brache developed his geocentric model of the Universe. Some of the historical contingencies are discussed in a c... Y Jeong - 《International Journal of Applied Science & Engineering Review》 被引量: 0发表: 2022年 ...
They are to be established as a result of further investigations. Formally the modification of geometry is very slight, as far as the distortion D is a small correction to the Minkowski world function. Nevertheless at the transition from (1.1) to (1.2) the space-time model changes qualitat...
Ptolemy was an astronomer, mathematician, and geographer who lived during the 2nd century CE. He is known for his geocentric (Earth-centred) model of the universe.
