The consensus of Earth and planetary scientists regards the chemical, i.e. rare-earth, isotopic, and bulk composition evidence as decisively demonstrating that tektites are derived from terrestrial crustal rock, i.e. sedimentary rocks, that are unlike any known lunar crust. [3] [10] [31]
The term First Temple is customarily used to describe the Temple of the pre-exilic period, which is thought to have been destroyed by the Babylonian conquest. It is described in the Bible as having been built by King Solomon and is understood to have been constructed with its Holy of Holies centered on a stone hilltop now known as the Foundation Stone which had been a traditional focus of ...
According to the Bible, Boaz (Hebrew: בֹּעַז , romanized: Bōʿaz) and Jachin (Hebrew: יָכִין , romanized: Yāḵīn) were two copper, brass or bronze pillars which stood on the porch of Solomon's Temple, the first Temple in Jerusalem. [1] They are used as symbols in Freemasonry and sometimes in religious architecture. They ...
In archaeology, space archaeology is the research-based study of various human-made items found in space, their interpretation as clues to the adventures humanity has experienced in space, and their preservation as cultural heritage.
Hypaethral is in contradistinction to cleithral, a term applied to a covered temple. [1] The hypaethros or hypaethral opening is the term Vitruvius (iii. 2) used for the opening in the middle of the roof of temples, an example being found in Athens in the temple of Jupiter Olympius, which is octastyle. There was no example in Rome. [2]
The structural theories of glass formation only consider the relative ease of glass formation. Materials which form glasses under a moderate cooling rate are called good glass formers, those that require a rapid cooling rate are called poor glass formers and those that require extreme cooling rates are referred to a non-glass formers.
The tendency for a material to form a glass while quenched is called glass-forming ability. This ability can be predicted by the rigidity theory . [ 13 ] Generally, a glass exists in a structurally metastable state with respect to its crystalline form, although in certain circumstances, for example in atactic polymers, there is no crystalline ...
In chemistry, the term chemically inert is used to describe a substance that is not chemically reactive.From a thermodynamic perspective, a substance is inert, or nonlabile, if it is thermodynamically unstable (positive standard Gibbs free energy of formation) yet decomposes at a slow, or negligible rate.
