    Mg] 2. Using equation 5, the formula can be simplified into the following form where the enthalpy of formation can be directly calculated: [v ⁠ ′ ′ ⁠ Mg] = exp (− ⁠ Δ f H / 2k B T ⁠ + ⁠ Δ f S / 2k B ⁠) = A exp (− ⁠ Δ f H / 2k B T ⁠), where A is a constant containing the entropic term.

  3. Evans balance - Wikipedia

    en.wikipedia.org/wiki/Evans_balance

    It can be measured using various devices that modify the shape of the magnetic field and measure resulting forces. [3] The Evans balance operates by measuring the force exerted on a magnet within a magnetic field shared with a sample as an indirect proxy for the magnetization of a sample, rather than by measuring the force exerted on the sample ...

    We can reduce the fractions to lowest terms by noting that the two occurrences of b on the left-hand side cancel, as do the two occurrences of d on the right-hand side, leaving =, and we can divide both sides of the equation by any of the elements—in this case we will use d —getting =.

    In the specific Gödel numbering used by Nagel and Newman, the Gödel number for the symbol "0" is 6 and the Gödel number for the symbol "=" is 5. Thus, in their system, the Gödel number of the formula "0 = 0" is 2 6 × 3 5 × 5 6 = 243,000,000.

    Simplification is the process of replacing a mathematical expression by an equivalent one that is simpler (usually shorter), according to a well-founded ordering. Examples include:

  8. Summation by parts - Wikipedia

    en.wikipedia.org/wiki/Summation_by_parts

    [2] Summation by parts is frequently used to prove Abel's theorem and Dirichlet's test. One can also use this technique to prove Abel's test: If is a convergent series, and a bounded monotone sequence, then = = converges. Proof of Abel's test.

  9. Degree of unsaturation - Wikipedia

    The formula for degree of unsaturation is: = + where n i is the number of atoms with valence v i. [2] That is, an atom that has a valence of x contributes a total of x − 2 to the degree of unsaturation. The result is then halved and increased by 1.
