[46] [47] If e γ is a rational number, then its denominator must be greater than 10 15000. [ 3 ] Euler's constant is conjectured not to be an algebraic period , [ 3 ] but the values of its first 10 9 decimal digits seem to indicate that it could be a normal number .

A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
±0.043 psi Lung air pressure difference moving the normal breaths of a person (only 0.3% of standard atmospheric pressure) [35] [36] 400–900 Pa 0.06–0.13 psi Atmospheric pressure on Mars, < 1% of atmospheric sea-level pressure on Earth [37] 610 Pa 0.089 psi Partial vapor pressure at the triple point of water (611.657 Pa) [38] [39] 10 3 Pa
Because of issues like this, template coders sometimes find themselves needing to distinguish between different combinations of three states: defined-and-non-blank, defined-and-blank, and undefined. This can be done in the following ways (the first positional parameter is used here, but named parameters work the same way).
Psi function can refer, in mathematics, to the ordinal collapsing function ψ ( α ) {\displaystyle \psi (\alpha )} the Dedekind psi function ψ ( n ) {\displaystyle \psi (n)}
Transition temperatures for the constituent elements have dashes ----- in the first column in a blank row, such as at 922 K, the melting point of Mg. Transition temperatures for the substance have two blank rows with dashes, and a center row with the defined transition and the enthalpy change, such as the melting point of MgCl 2 at 980 K. The ...
Feet of water is an alternative way to specify pressure as height of a water column; it is conventionally equated to 2,989.067 pascals (0.4335275 psi). [ 3 ] In North America , air and other industrial gases are often measured in inches of water when at low pressure.
