  2. 4Pi microscope - Wikipedia

    en.wikipedia.org/wiki/4Pi_Microscope

    A 4Pi microscope is a laser scanning fluorescence microscope with an improved axial resolution.With it the typical range of the axial resolution of 500–700 nm can be improved to 100–150 nm, which corresponds to an almost spherical focal spot with 5–7 times less volume than that of standard confocal microscopy.

  4. Littelmann path model - Wikipedia

    en.wikipedia.org/wiki/Littelmann_path_model

    There is a directed arrow from one path to another labelled by the simple root α, if the target path is obtained from the source path by applying f α. The Littelmann graphs of two paths are isomorphic as coloured, directed graphs if and only if the paths have the same end point. The Littelmann graph therefore only depends on λ.

    The value 4π×10 −7 N·A −2 is exact. There is only really one experimentally determined constant in electromagnetism, that being the speed of light. The permeability of free space is fixed at exactly 4π×10 −7 N·A −2 and any uncertainty is carried by the permittivity of free space.70.253.89.209 16:45, 17 September 2008 (UTC)
