Input: Read this: Another theory describes its derivation from a non-Slavic warrior class,:42, 6466 forming a distinct element known as the Lechici/Lekhi (Lechitow):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern Indiaan aristocracy of equalitysettled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
Question: WHat caste system does the hindu society have?

The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J. de Solla Price. It was designed to calculate astronomical positions. It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The Antikythera mechanism was thought to be the first computer according to whom?
Ah, so.. Derek J. de Solla Price.

Question: Greek surnames were widely in use by the 9th century supplanting the ancient tradition of using the father's name, however Greek surnames are most commonly patronymics. Commonly, Greek male surnames end in -s, which is the common ending for Greek masculine proper nouns in the nominative case. Exceptionally, some end in -ou, indicating the genitive case of this proper noun for patronymic reasons. Although surnames in mainland Greece are static today, dynamic and changing patronymic usage survives in middle names where the genitive of father's first name is commonly the middle name (this usage having been passed on to the Russians). In Cyprus, by contrast, surnames follow the ancient tradition of being given according to the father's name. Finally, in addition to Greek-derived surnames many have Latin, Turkish and Italian origin.

Context and question: As in the Scheiner system, speeds were expressed in 'degrees'. Originally the sensitivity was written as a fraction with 'tenths' (for example "18/10 DIN"), where the resultant value 1.8 represented the relative base 10 logarithm of the speed. 'Tenths' were later abandoned with DIN 4512:1957-11, and the example above would be written as "18 DIN". The degree symbol was finally dropped with DIN 4512:1961-10. This revision also saw significant changes in the definition of film speeds in order to accommodate then-recent changes in the American ASA PH2.5-1960 standard, so that film speeds of black-and-white negative film effectively would become doubled, that is, a film previously marked as "18 DIN" would now be labeled as "21 DIN" without emulsion changes.
What replaced the American ASA PH2.5-1960 standard?
