Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population.
double x = 1.000000000000001; // rounded to 1 + 5*2^{-52} double y = 1.000000000000002; // rounded to 1 + 9*2^{-52} double z = y-x; // difference is exactly 4*2^{-52} The difference 1.000000000000002 − 1.000000000000001 {\displaystyle 1.000000000000002-1.000000000000001} is 0.000000000000001 = 1.0 × 10 − 15 {\displaystyle 0.000000000000001 ...
In the International System of Units (SI), the coherent unit for molar concentration is mol/m 3. However, most chemical literature traditionally uses mol/dm 3, which is the same as mol/L. This traditional unit is often called a molar and denoted by the letter M, for example: 1 mol/m 3 = 10 −3 mol/dm 3 = 10 −3 mol/L = 10 −3 M = 1 mM = 1 ...
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
The stars in the innermost 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The Galactic Center is an intense radio source known as Sagittarius A*, a supermassive black hole of 4.100 (± 0.034) million solar masses.

[4] The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture , but not emissions from land use, land-use change and forestry . [ n 2 ] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 ...
