A Blog for Dallas Area Catholics Encyclopedia Coptica: The Christian Coptic Orthodox Church Of Egypt The Christian Coptic Orthodox Church Of Egypt Encyclopedia Coptica is Courtesy of The word Copt is derived from the Greek word Aigyptos, which was, in turn, derived from "Hikaptah", one of the names for Memphis, the first capital of Ancient Egypt. The modern use of the term "Coptic" describes Egyptian Christians, as well as the last stage of the ancient Egyptian language script. Also, it describes the distinctive art and architecture that developed as an early expression of the new faith. The Coptic Church is based on the teachings of Saint Mark who brought Christianity to Egypt during the reign of the Roman emperor Nero in the first century, a dozen of years after the Lord's ascension. Although fully integrated into the body of the modern Egyptian nation, the Copts have survived as a strong religious entity who pride themselves on their contribution to the Christian world. The contributions of the Coptic Church to Christendom are many. Last Updated: January 2006 References: Translations:
Atomic Rocket main page Your imagination has been captured by the roaring rockets from Heinlein's SPACE CADET or the Polaris from TOM CORBETT, SPACE CADET. But are such rockets possible? How does one go about defining the performance of these atomic-powered cruisers? This document gives some hints and equations that will allow back-of-the-envelope calculations on such matters. Though horribly simplistic, they are far better than just making up your figures. This site was mainly intended for science fiction authors who wanted a little scientific accuracy so they can write SF "the way God and Heinlein intended" (Arlan Andrews's Law). The engine and the torchship pages explain how easily do some of the calculations using Nomograms. . While this site originally focused on rocketry equations, as you can see it has grown to encompass other topics of interest to SF authors and game designers.
