Galileo, Copernicus, Ptolemy. All known that the planets orbit the Sun.
But the teaching program "said" "the Sun orbits the Earth."
Not the teaching program in general, only some fairytale book from
the old ages that some people consider authoritative.
"Some people" consider the Fresnel's idea and Heaviside's equations as
authoritative.
"" In 1817, Young had proposed a small transverse component to light, while
yet retaining a far larger longitudinal component. Fresnel, by the year
1821, was able to show via mathematical methods that polarization could be
explained only if light was entirely transverse, with no longitudinal
vibration whatsoever.
From:
http://en.wikipedia.org/wiki/Fresnel
But some people know that Young is right and that: ""Light is the
oscillatory flow of electrons".
This small transverse component is because the light is radiated by dipole.
Radio waves radiated from monopole are the pressure waves (oscillatory
flow).
