  2. Pythagorean tuning - Wikipedia

    en.wikipedia.org/wiki/Pythagorean_tuning

    The purpose of this adjustment is to move the 12 notes within a smaller range of frequency, namely within the interval between the base note D and the D above it (a note with twice its frequency). This interval is typically called the basic octave (on a piano keyboard, an octave has only 12 keys).

  3. Musical tuning - Wikipedia

    en.wikipedia.org/wiki/Musical_tuning

    In just intonation, the frequencies of the scale notes are related to one another by simple numeric ratios, a common example of this being ⁠ 1 / 1 ⁠, ⁠ 9 / 8 ⁠, ⁠ 5 / 4 ⁠, ⁠ 4 / 3 ⁠, ⁠ 3 / 2 ⁠, ⁠ 5 / 3 ⁠, ⁠ 15 / 8 ⁠, ⁠ 2 / 1 ⁠ to define the ratios for the seven notes in a C major scale, plus the return to the ...

  4. Scale analysis (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Scale_analysis_(mathematics)

    Scale analysis rules as follows: Rule1-First step in scale analysis is to define the domain of extent in which we apply scale analysis. Any scale analysis of a flow region that is not uniquely defined is not valid. Rule2-One equation constitutes an equivalence between the scales of two dominant terms appearing in the equation. For example,

  5. Non-dimensionalization and scaling of the Navier–Stokes equations

    en.wikipedia.org/wiki/Non-dimensionalization_and...

    In addition to reducing the number of parameters, non-dimensionalized equation helps to gain a greater insight into the relative size of various terms present in the equation. [1] [2] Following appropriate selecting of scales for the non-dimensionalization process, this leads to identification of small terms in the equation. Neglecting the ...

  6. 12 equal temperament - Wikipedia

    en.wikipedia.org/wiki/12_equal_temperament

    12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).

  7. Scale parameter - Wikipedia

    en.wikipedia.org/wiki/Scale_parameter

    This scale factor is defined as the theoretical value of the value obtained by dividing the required scale parameter by the asymptotic value of the statistic. Note that the scale factor depends on the distribution in question. For instance, in order to use the median absolute deviation (MAD) to estimate the standard deviation of the normal ...

  8. Renormalization group - Wikipedia

    en.wikipedia.org/wiki/Renormalization_group

    A change in scale is called a scale transformation. The renormalization group is intimately related to scale invariance and conformal invariance, symmetries in which a system appears the same at all scales (self-similarity), [a] where under the fixed point of the renormalization group flow the field theory is conformally invariant.

  9. Friedmann equations - Wikipedia

    en.wikipedia.org/wiki/Friedmann_equations

    The term Friedmann equation sometimes is used only for the first equation. [3] In these equations, R(t) is the cosmological scale factor, is the Newtonian constant of gravitation, Λ is the cosmological constant with dimension length −2, ρ is the energy density and p is the isotropic pressure.
