Input (English): The Wigner D-matrix satisfies a number of differential properties if space-fixed operators of this quantity are introduced and the summation of this quantity can be governed by using Clebsch-Gordon coefficients. In quantum mechanics, the spherical harmonics are eigenfunctions of this quantity and they obey a commutation relation equal to I times h-bar times this quantity in the mutually (*) orthogonal direction. The time derivative of this quantity is equal to torque and its conservation is demonstrated in Kepler's Second Law. Planck's constant has the dimensions of, FTP, what conserved quantity symbolized L and defined as the cross product of a position vector and linear momentum.
Output (English): Science
