real-number constant
51Class number problem — In mathematics, the Gauss class number problem (for imaginary quadratic fields), as usually understood, is to provide for each n ≥ 1 a complete list of imaginary quadratic fields with class number n. It is named after the great… …
52De Bruijn–Newman constant — The De Bruijn–Newman constant, denoted by Λ and named after Nicolaas Govert de Bruijn and Charles M. Newman, is a mathematical constant defined via the zeros of a certain function H(λ, z), where λ is a real parameter and z is a complex… …
53Boltzmann constant — For the constant pertaining to energy of black body radiation see Stefan–Boltzmann constant Values of k[1] Units 1.3806488(13)×10−23 J K−1 8.617332 …
54Azimuthal quantum number — The azimuthal quantum number (or orbital angular momentum quantum number, second quantum number) symbolized as ℓ (lower case L) is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the… …
