Wheel And Axle
The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other. The wheel and axle can be viewed as a version of the lever, with a drive force applied tangentially to the perimeter of the wheel, and a load force applied to the axle supported in a bearing, which serves as a fulcrum. History The Halaf culture of 6500–5100 BCE has been credited with the earliest depiction of a wheeled vehicle, but this is doubtful as there is no evidence of Halafians using either wheeled vehicles or even pottery wheels. One of the first applications of the wheel to appear was the potter's wheel, used by prehistoric cultures to fabricate clay pots. The earliest type, known as "tournettes" or "slow wheels", were known in the Middle East by the 5th millennium BCE. One of the earliest examples was discovered at Tepe Pardis, Iran, and dated to 5200–4700 BCE. These were ...

Near East
The ''Near East''; he, המזרח הקרוב; arc, ܕܢܚܐ ܩܪܒ; fa, خاور نزدیک, Xāvar-e nazdik; tr, Yakın Doğu is a geographical term which roughly encompasses a transcontinental region in Western Asia, that was once the historical Fertile Crescent, and later the Levant region. It also comprises Turkey (both Anatolia and East Thrace) and Egypt (mostly located in North Africa, with the Sinai Peninsula being in Asia). Despite having varying definitions within different academic circles, the term was originally applied to the maximum extent of the Ottoman Empire. According to the National Geographic Society, the terms ''Near East'' and ''Middle East'' denote the same territories and are "generally accepted as comprising the countries of the Arabian Peninsula, Cyprus, Egypt, Iraq, Iran, Israel, Jordan, Lebanon, Palestinian territories, Syria, and Turkey". In 1997, the Food and Agriculture Organization of the United Nations, Food and Agriculture Organization (FAO) ...

Baden Culture
The Baden culture was a Chalcolithic archaeological culture, culture from 3520–2690 BC. It was found in Central Europe, Central and Southeast Europe, and is in particular known from Moravia (Czech Republic), Hungary, southern Poland, Slovakia, northern Croatia and eastern Austria. Imports of Baden pottery have also been found in Germany and Switzerland (Arbon, Arbon-Bleiche III). History of research The Baden culture was named after Baden bei Wien, Baden near Vienna by the Austrian prehistorian Oswald Menghin. It is also known as the Ossarn group or Pecel culture. The first monographic treatment was produced by J. Banner in 1956. Other important scholars are E. Neustupny, Ida Bognar-Kutzian and Vera Nemejcova-Pavukova. Baden has been interpreted as part of a much larger archaeological complex encompassing cultures at the mouth of the Danube (Ezero culture, Ezero-Cernavoda III) and the Troad. In 1963, Nándor Kalicz had proposed a connection between the Baden culture and Tr ...

Prehistoric Pile Dwellings Around The Alps
Prehistoric pile dwellings around the Alps are a series of prehistoric pile dwelling (or stilt house) settlements in and around the Alps built from about 5000 to 500 BC on the edges of lakes, rivers or wetlands. In 2011, 111 sites located variously in Switzerland (56), Italy (19), Germany (18), France (11), Austria (5) and Slovenia (2) were added to the UNESCO World Heritage Site list. In Slovenia, these were the first World Heritage Sites to be listed for their cultural value. Excavations conducted at some of the sites have yielded evidence regarding prehistoric life and the way communities interacted with their environment during the Neolithic and Bronze Ages in Alpine Europe. These settlements are a unique group of exceptionally well-preserved and culturally rich archaeological sites, which constitute one of the most important sources for the study of early agrarian societies in the region. Contrary to popular belief, the dwellings were not erected over water, but on nearby ma ...

Standard Deviations
In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. Standard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lower case Greek letter σ (sigma), for the population standard deviation, or the Latin letter '' s'', for the sample standard deviation. The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data. The standard deviation of a popul ...

Ljubljana Marshes Wooden Wheel
The Ljubljana Marshes Wheel is a wooden wheel that was found in the Ljubljana Marsh some south of Ljubljana, the capital of Slovenia, in 2002. Radiocarbon dating, performed in the VERA laboratory (Vienna Environmental Research Accelerator) in Vienna, showed that it was approximately 5,100-5,350 years old, which makes it the oldest wooden wheel yet discovered. It was discovered by a team of Slovene archeologists from the Ljubljana Institute of Archaeology, a part of the Research Center at the Slovene Academy of Arts and Sciences, under the guidance of Anton Velušček. The archaeological site Remains of pile dwellings were discovered in the Ljubljana Marsh as early as in 1875. Since 2011, the site has been protected as a UNESCO World Heritage Site as an example of prehistoric pile dwellings around the Alps, a special form of dwellings in areas with lakes and marshes. The archaeologists at the excavation site identified over one thousand piles in the bed of the Iška River, near ...

Funnelbeaker Culture
The Funnel(-neck-)beaker culture, in short TRB or TBK (german: Trichter(-rand-)becherkultur, nl, Trechterbekercultuur; da, Tragtbægerkultur; ) was an archaeological culture in north-central Europe. It developed as a technological merger of local neolithic and mesolithic techno-complexes between the lower Elbe and middle Vistula rivers. These predecessors were the Lengyel-influenced Stroke-ornamented ware culture (STK) groups/Late Lengyel and Baden-Boleráz in the southeast, Rössen groups in the southwest and the Ertebølle-Ellerbek groups in the north. The TRB introduced farming and husbandry as a major source of food to the pottery-using hunter-gatherers north of this line. The TRB techno-complex is divided into a northern group including modern northern Germany and southern Scandinavia (TRB-N, roughly the area that previously belonged to the Ertebølle-Ellerbek complex), a western group in the Netherlands between the Zuiderzee and lower Elbe that originated in the Swifte ...

Bronocice Pot
The Bronocice pot is a ceramic vase incised with one of the earliest known depictions of what may be a wheeled vehicle. It was discovered in the village of Bronocice near the Nidzica River in Poland. Attributed to the Funnelbeaker archaeological culture, radiocarbon tests dated the pot to the mid-fourth millennium BCE. Today it is housed at the Archaeological Museum of Kraków in southern Poland. Discovery The pot was discovered between 1974 and 1976 during the archaeological excavation of a large Neolithic settlement in Bronocice, ca. 50 km to north east of Kraków. The excavations were carried out between 1974 and 1980 by the Institute of Archaeology and Ethnology, Polish Academy of Sciences and the State University of New York at Buffalo (United States). Sarunas Milisauskas, one of several archaeologists who worked on Bronocice excavation project wrote: "The 1974 field season yielded data beyond our expectations. An incised wagon motif was found on a Funnelbeaker ve ...
