Adelard of Bath
Adelard of Bath (; 1080 1152 AD) was a 12th-century English natural philosopher. He is known both for his original works and for translating many important Arabic and Greek scientific works of astrology, astronomy, philosophy and mathematics into Latin from Arabic versions, which were then introduced to Western Europe. He is known as one of the first to introduce the Arabic numeral system to Europe. He stands at the convergence of three intellectual schools: the traditional learning of French schools, the Greek culture of Southern Italy, and the Arabic science of the East.
Automobile model numbering system in the Soviet Union and Russia
The modern numbering system, documented as отраслевая нормаль (industry standard) ОН 025270-66, was first introduced in 1966 (but did not become effective immediately, so many vehicles that entered production before the mid-1970s still used the old numbering system; the first vehicle to use it was the all-new VAZ-2101, other plants switched to the new system later: Moskvitch - in 1976, Moskvitch 2140; GAZ - in 1982, GAZ-3102; and so on) and is still used in Russia, although not strictly adhered to by the manufacturers.
