  2. Scaling (geometry) - Wikipedia

    en.wikipedia.org/wiki/Scaling_(geometry)

    The scaling is uniform if and only if the scaling factors are equal (v x = v y = v z). If all except one of the scale factors are equal to 1, we have directional scaling. In the case where v x = v y = v z = k, scaling increases the area of any surface by a factor of k 2 and the volume of any solid object by a factor of k 3.

  3. Stretched exponential function - Wikipedia

    en.wikipedia.org/wiki/Stretched_exponential_function

    The compressed exponential function (with β > 1) has less practical importance, with the notable exceptions of β = 2, which gives the normal distribution, and of compressed exponential relaxation in the dynamics of amorphous solids. [1] In mathematics, the stretched exponential is also known as the complementary cumulative Weibull distribution.

  4. Shear mapping - Wikipedia

    en.wikipedia.org/wiki/Shear_mapping

    In this case, the displacement is horizontal by a factor of 2 where the fixed line is the x-axis, and the signed distance is the y-coordinate. Note that points on opposite sides of the reference line are displaced in opposite directions. Shear mappings must not be confused with rotations.

  5. Liouville's equation - Wikipedia

    en.wikipedia.org/wiki/Liouville's_equation

    Liouville's equation appears in the study of isothermal coordinates in differential geometry: the independent variables x,y are the coordinates, while f can be described as the conformal factor with respect to the flat metric. Occasionally it is the square f 2 that is referred to as the conformal factor, instead of f itself.

  6. Pauli equation - Wikipedia

    en.wikipedia.org/wiki/Pauli_equation

    Pauli's equation is derived by requiring minimal coupling, which provides a g-factor g=2. Most elementary particles have anomalous g -factors, different from 2. In the domain of relativistic quantum field theory , one defines a non-minimal coupling, sometimes called Pauli coupling, in order to add an anomalous factor

  7. Length contraction - Wikipedia

    en.wikipedia.org/wiki/Length_contraction

    [2] [3] Although both FitzGerald and Lorentz alluded to the fact that electrostatic fields in motion were deformed ("Heaviside-Ellipsoid" after Oliver Heaviside, who derived this deformation from electromagnetic theory in 1888), it was considered an ad hoc hypothesis, because at this time there was no sufficient reason to assume that ...

    Overall, you can lose between 1 to 3 inches in height as you age, per Medline Plus. While age-related height loss is normal, there are times when it's a sign of an underlying health condition.

  9. Prandtl–Glauert transformation - Wikipedia

    en.wikipedia.org/wiki/Prandtl–Glauert...

    The interest in compressibility research emerged after the WWI, when the aircraft propeller tips started to reach M=0.8. Ludwig Prandtl had taught the transformation in his lectures about 1922, however the first rigorous proof was published in 1928 by Hermann Glauert. [5]
