Harmonical mean (Arith. & Alg.), certain relations of numbers and quantities, which bear an analogy
to musical consonances. Harmonic motion, the motion of the point A, of the foot of the perpendicular
PA, when P moves uniformly in the circumference of a circle, and PA is drawn perpendicularly upon a
fixed diameter of the circle. This is simple harmonic motion. The combinations, in any way, of two or
more simple harmonic motions, make other kinds of harmonic motion. The motion of the pendulum bob
of a clock is approximately simple harmonic motion. Harmonic proportion. See under Proportion.
Harmonic series or progression. See under Progression. Spherical harmonic analysis, a
mathematical method, sometimes referred to as that of Laplace's Coefficients, which has for its object
the expression of an arbitrary, periodic function of two independent variables, in the proper form for a
large class of physical problems, involving arbitrary data, over a spherical surface, and the deduction of
solutions for every point of space. The functions employed in this method are called spherical harmonic
functions. Thomson & Tait. Harmonic suture (Anat.), an articulation by simple apposition of
