Egyptian pyramids

Also, they did not share the same basic design function. The Egyptian pyramids were private tombs meant to separate the pharaoh s remains from the mainstream of society and protect him for eternity, while the pyramids of Mesoamerica were primarily public temples of ritual and celebration. [Pg.126]

In ancient cases like the construction of the Egyptian pyramids, muscle power did not have a competing mechanical alternative. [Pg.4]

Which mathematical models or designing procedures were used to build the Egyptian pyramids or the gothic cathedrals Since the ancient times, geometric scaling-up procedures have been used. These rules are based on similitude laws, which are still used today. [Pg.527]

People have been using cementing materials for thousands of years. The stones in the Egyptian pyramids are held together by a mixture of sand and the mineral compound gypsum, which is calcimn sulfate dihydrate. When this dihydrate is heated, water evaporates, forming a compound with one water molecule per two calcimn sulfate formula units. Today, we know this binding material as plaster of paris. [Pg.167]

What do apiece of wood from an Egyptian pyramid, a bone tool from an archaeological dig, and the Dead Sea Scrolls have in common They all contain carbon from dead organisms. Thus, archaeologists can determine the objects ages by the carbon-14 method. [Pg.754]

How do scientists determine the ages of artifacts from archaeological excavations If someone tried to sell you a manuscript supposedly dating from 1000 B.C., how could you be certain of its authenticity Is a mummy found in an Egyptian pyramid really three thousand years old Is the so-called Shroud of Turin truly the burial cloth of Jesus Christ The answers to these and other similar questions can usually be found by applying chemical kinetics and the radiocarbon dating technique. [Pg.527]

Genesis 50 deals with the death of Joseph and the dispatch of his bones to rest with his ancestors in Jerusalem. So perhaps the Knights Templar found Joseph s Egyptian mummy under the Temple in Jerusalem. This explanation is consistent with Shugborough s inscription and the additional ossuary with its Egyptian pyramid top. [Pg.373]

At first people used only native copper but later rising demand led to the processing of copper ores. It is comparatively simple to smelt the metal from ores with high copper content. As early as the third millenium B.C. copper was widely used for manufacturing various tools. The Egyptian Pyramid of Cheops was built with gigantic stone blocks each of which was hewn with copper tools. [Pg.30]

Two requirements must be met to obtain biologically-mediated mineralization of a polymer it must be exposed to a biotic environment conducive to degradation and its chemical structure must be amenable to breakdown by the available set of microbial enzymes in that environment. Thus, even the inherently biodegradable starch in grains (barley and wheat) found in Egyptian pyramids was preserved over millennia because of the dry and dark environment they were stored in. [Pg.146]

As a rock, gypsum has been found as stone ashlars and statues in the Ancient Mesopotamia [1]. However, one of the most important uses of gypsum was conglomerate material as mortar manufacturing. Archaeological studies reported the use of gypsum mortars from the Egyptian pyramids, 4 ka BP [2]. [Pg.132]

Iron objects are depicted in the wall paintings of the Egyptian pyramids and always with a blue color. The butcher has a blue grinding tool hanging at his hip, the carpenter has blue tools for woodworking. The metal iron was called benipe, a word that probably has the meaning metal from heaven, a reason for the blue color [8.4]. [Pg.175]
