0( 95−15) μs
0 (zero) is a number representing an empty quantity. In place-value notation such as the Hindu–Arabic numeral system, 0 also serves as a placeholder numerical digit, which works by multiplying digits to the left of 0 by the radix, usually by 10. As a number, 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and other algebraic structures. Common names for the number 0 in English are ''zero'', ''nought'', ''naught'' (), ''nil''. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as ''oh'' or ''o'' (). Informal or slang terms for 0 include ''zilch'' and ''zip''. Historically, ''ought'', ''aught'' (), and ''cipher'', have also been used. Etymology The word ''zero'' came into the English language via French from the Italian , a contraction of the Venetian form of Italian via ''ṣafira'' or ''ṣifr''. In pre-Islamic time the word (Arabic ) had th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O Mark
An O mark, also known as Marujirushi () in Japan and Gongpyo (, ball mark) in Korea, is the name of the symbols "◯" or "⭕" used to represent affirmation in East Asia, similar to its Western equivalent of the tick (check mark), checkmark. Its opposite is the X mark ("✗") or ("×"). Hanamaru The is a variant of the O mark used in Japan, written as . It is typically drawn as a spiral surrounded by rounded flower petals, suggesting a flower. It is frequently used in praising or complimenting children, and the motif often appears in children's characters and logos. The hanamaru is frequently written on tests if a student has achieved full marks or an otherwise outstanding result. It is sometimes used in place of an O mark in grading written response problems if a student's answer is especially good. Some teachers will add more rotations to the spiral the better the answer is. It is also used as a symbol for good weather. Unicode Unicode provides various related symbols, inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radix
In a positional numeral system, the radix or base is the number of unique digits, including the digit zero, used to represent numbers. For example, for the decimal/denary system (the most common system in use today) the radix (base number) is ten, because it uses the ten digits from 0 through 9. In any standard positional numeral system, a number is conventionally written as with ''x'' as the string of digits and ''y'' as its base, although for base ten the subscript is usually assumed (and omitted, together with the pair of parentheses), as it is the most common way to express value. For example, (the decimal system is implied in the latter) and represents the number one hundred, while (100)2 (in the binary system with base 2) represents the number four. Etymology ''Radix'' is a Latin word for "root". ''Root'' can be considered a synonym for ''base,'' in the arithmetical sense. In numeral systems In the system with radix 13, for example, a string of digits such as 398 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anemoi
In ancient Greek religion and myth, the Anemoi (Greek: , 'Winds') were wind gods who were each ascribed a cardinal direction from which their respective winds came (see Classical compass winds), and were each associated with various seasons and weather conditions. They were the progeny of the goddess of the dawn Eos and her husband Astraeus. Etymology The earliest attestation of the word in Greek and of the worship of the winds by the Greeks, are perhaps the Mycenaean Greek word-forms , , , , i.e. 'priestess of the winds'. These words, written in Linear B, are found on the KN Fp 1 and KN Fp 13 tablets. Mythology The Anemoi are minor gods and are subject to the god Aeolus. They were sometimes represented as gusts of wind, and at other times were personified as winged men.
