The usual English proper name for Earth's natural satellite is simply Moon, with a capital M. [19] [20] The noun moon is derived from Old English mōna, which (like all its Germanic cognates) stems from Proto-Germanic *mēnōn, [21] which in turn comes from Proto-Indo-European *mēnsis 'month' [22] (from earlier *mēnōt, genitive *mēneses) which may be related to the verb 'measure' (of time).
In May 2006, Snowden wrote in Ars Technica that he had no trouble getting work because he was a "computer wizard". [39] Snowden was sent to the CIA's secret school for technology specialists, where he lived in a hotel for six months while studying and training full-time.
Workers were paid in grain; a simple laborer might earn 5 + 1 ⁄ 2 sacks (200 kg or 400 lb) of grain per month, while a foreman might earn 7 + 1 ⁄ 2 sacks (250 kg or 550 lb). Prices were fixed across the country and recorded in lists to facilitate trading; for example a shirt cost five copper deben, while a cow cost 140 deben. [ 78 ]
An autoclave is a machine used to carry out industrial and scientific processes requiring elevated temperature and pressure in relation to ambient pressure and/or temperature. Autoclaves are used before surgical procedures to perform sterilization and in the chemical industry to cure coatings and vulcanize rubber and for hydrothermal synthesis .
Silicone caulk can be used as a basic sealant against water and air penetration. In organosilicon and polymer chemistry, a silicone or polysiloxane is a polymer composed of repeating units of siloxane (−O−R 2 Si−O−SiR 2 −, where R = organic group).
The laws describing the behaviour of gases under fixed pressure, volume, amount of gas, and absolute temperature conditions are called Gas Laws.The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Simon was a relay-based electromechanical computer, described by Edmund Berkeley in a series of thirteen construction articles in Radio-Electronics magazine, from October 1950. Intended for the educational purpose of demonstrating the concept of a digital computer, it could not be used for any significant practical computation since it had only ...
