# Meaning of 'Harmonic'

February 7th Fact-of-the-DayThe term 'harmonic'
has several meanings in science and mathematics, some of which
have little or no obvious relationship to each other. Ask a radio engineer
what a harmonic is and you probably will be told it is a frequency that
is an integer multiple of a fundamental frequency. Ask a scientist or
mathematician and you might be told it is the frequency resulting from
simple harmonic motion which also is called harmonic oscillation (a fundamental
sinusoidal frequency), or you might be told that a harmonic range is a
set of four collinear points arranged in a certain way along a ling segment,
or you might be told about harmonic means which have nothing to do with
sinusoidal frequency. The term 'harmonic' probably originated in music
theory where it refers to notes having small integer frequency ratios
that harmonize when played together. *©2005 Martek International All
