  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  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  more  simple  harmonic  motions,  make  other  kinds  of  harmonic 
  motion.  The  motion  of  the  pendulum  bob  of  a  clock  is 
  approximately  simple  harmonic  motion.

  {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
