A contemporary look at the Equation of Time

Every single heliocentric astronomical insight depends on the ability
to isolate axial rotation from orbital motion,the original insight of
Copernicus in isolating the orbital motion of the Earth against the
common heliocentric motion of the other planets is based on demolishing
the notion that the Sun moves around the Earth as a daily occurence.

As the main interest of the late 17th and 18th centuries in celestial
observation was the determination of terrestial longitudes through
celestial means,the proponents of the celestial sphere method returned
to a geocentric position on the motion of the Sun and rendered the
Equation of Time principles based on axial tilt -

The childish analemma emerged from such poor astronomical rendering of
the Equation of Time ,based on the hemisphericaly plotted position of
the Sun against the Equator using an equable 24 hour clock,the entire
astronomical significance of the original Equation of Time correction
became lost,even the two step process which links the pre-Copernican
equable 24 hour day to its heliocentric adaption.

This is a terrible wrong on all counts,historically,technically and
more importantly it infects the ability to intellectually and
intuitively work with productive astronomical principles for such
things as climatology and geology.

Being incorrect by 3 minutes 56 seconds Each Day for the value for
axial rotation must be the biggest festering sore ever,it is so
important to restore the correct value in order to appreciate
heliocentricity or orbital motion in isolation as it is for restoring
axial rotation in isolation for pragmatic purposes such as Earth
sciences.
