    Philip McCord Morse (August 6, 1903 – 5 September 1985), was an American physicist, administrator and pioneer of operations research (OR) in World War II. [1] He is considered to be the father of operations research in the U.S.

  6. Prolate spheroidal coordinates - Wikipedia

    en.wikipedia.org/wiki/Prolate_spheroidal_coordinates

    Prolate spheroidal coordinates μ and ν for a = 1.The lines of equal values of μ and ν are shown on the xz-plane, i.e. for φ = 0.The surfaces of constant μ and ν are obtained by rotation about the z-axis, so that the diagram is valid for any plane containing the z-axis: i.e. for any φ.

  7. Parabolic coordinates - Wikipedia

    en.wikipedia.org/wiki/Parabolic_coordinates

    The scale factors for the parabolic coordinates (,) are equal = = + Hence, the infinitesimal element of area is = (+) and the Laplacian equals = + (+) Other differential operators such as and can be expressed in the coordinates (,) by substituting the scale factors into the general formulae found in orthogonal coordinates.

    Figure 2: Plot of the oblate spheroidal coordinates μ and ν in the x-z plane, where φ is zero and a equals one. The curves of constant μ form red ellipses, whereas those of constant ν form cyan half-hyperbolae in this plane.

  9. Feshbach resonance - Wikipedia

    en.wikipedia.org/wiki/Feshbach_resonance

    In physics, a Feshbach resonance can occur upon collision of two slow atoms, when they temporarily stick together forming an unstable compound with short lifetime (so-called resonance). [1] It is a feature of many-body systems in which a bound state is achieved if the coupling(s) between at least one internal degree of freedom and the reaction ...
