In the 3rd century BCE, Archimedes proved the sharp inequalities 223 ⁄ 71 < π < 22 ⁄ 7, by means of regular 96-gons (accuracies of 2·10 −4 and 4·10 −4, respectively). [ 15 ] In the 2nd century CE, Ptolemy used the value 377 ⁄ 120 , the first known approximation accurate to three decimal places (accuracy 2·10 −5 ). [ 16 ]
Also confidence coefficient. A number indicating the probability that the confidence interval (range) captures the true population mean. For example, a confidence interval with a 95% confidence level has a 95% chance of capturing the population mean. Technically, this means that, if the experiment were repeated many times, 95% of the CIs computed at this level would contain the true population ...
A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface.
The term myriometer (abbr. mom, equivalent to 100 micrometers; frequently confused with the myriameter, 10 kilometers) [98] is deprecated; the decimal metric prefix myrio-[99] is obsolete [100] [101] [102] and was not included among the prefixes when the International System of Units was introduced in 1960. 100 μm – 1/10 of a millimeter
The octal representation is formed by the quotients, written in the order generated by the algorithm. For example, to convert 125 10 to octal: 125 = 8 2 × 1 + 61 61 = 8 1 × 7 + 5 5 = 8 0 × 5 + 0. Therefore, 125 10 = 175 8. Another example: 900 = 8 3 × 1 + 388 388 = 8 2 × 6 + 4 4 = 8 1 × 0 + 4 4 = 8 0 × 4 + 0. Therefore, 900 10 = 1604 8.

World map of total annual healthcare expenditure by country as a share of GDP. [1]This article includes 2 lists of countries of the world and their total expenditure on health as a percent of national gross domestic product (GDP).
Viscosity is a measure of a fluid's rate-dependent resistance to a change in shape or to movement of its neighboring portions relative to one another. [1] For liquids, it corresponds to the informal concept of thickness; for example, syrup has a higher viscosity than water. [2]
