In general, a common fraction is said to be a proper fraction if the absolute value of the fraction is strictly less than one—that is, if the fraction is greater than −1 and less than 1. [14] [15] It is said to be an improper fraction, or sometimes top-heavy fraction, [16] if the absolute value of the fraction is greater than or equal to 1 ...
The absolute value of this quantity ( … ) corresponds to the length ratio taken in reverse order (shorter segment length over longer segment length, / ). This illustrates the unique property of the golden ratio among positive numbers, that 1 φ = φ − 1 , {\displaystyle {\frac {1}{\varphi }}=\varphi -1,}
The numeric values on the International Chronostratigrahpic Chart are represented by the unit Ma (megaannum, for 'million years'). For example, 201.4 ± 0.2 Ma, the lower boundary of the Jurassic Period, is defined as 201,400,000 years old with an uncertainty of 200,000 years.
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.
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
[254] [255] A 2014 analysis of the carbon footprint literature by the Intergovernmental Panel on Climate Change (IPCC) reported that the embodied total life-cycle emission intensity of nuclear power has a median value of 12 g CO 2 eq/kWh, which is the lowest among all commercial baseload energy sources.
A one percent expansion of volume typically requires a temperature increase on the order of thousands of degrees Celsius. In contrast, the density of gases is strongly affected by pressure. The density of an ideal gas is ρ = M P R T , {\\displaystyle \\rho ={\\frac {MP}{RT}},}
From 1871 to 1913, "the average U.S. tariff on dutiable imports never fell below 38 percent [and] gross national product (GNP) grew 4.3 percent annually, twice the pace in free trade Britain and well above the U.S. average in the 20th century," notes Alfred Eckes Jr, chairman of the U.S. International Trade Commission under President Reagan.
