I am preparing a presentation on the Equation of Time and have been trying
to find a clear description, preferable with diagrams, of the adjustment
due to obliquity.

The explanation at the National Maritime Museum
http://www.nmm.ac.uk/server/show/conWebDoc.351 only makes sense if you
already know the answer

The best I could find was the page at
http://www.wallingfordclock.talktalk.net/Sidereal%20Time.htm but I still
find it inadequate.

The example of the bus going down the incline is good to show the slowdown
but I cannot find anything appropriate to explain the speeding up.

Has anyone seen and better presented explanations?

Does this have what you're looking for
http://www.analemma.com/
?

Thanks - that looks very interesting.

I have to laugh,many look down at the Americans with the minority of
creationists who live there whereas on this side of the ocean there
are those who are full blown astrologers -

The Equation of Time is a global correction applied to the total
length of the natural noon cycle,to believe that there is some sort of
hemispherical variable axial inclination involved,hence the analemma
hoax, is basically to be on intellectual par with a flat Earther.The
analemma must be some sort of eccentric English joke ,in which
case,it is not funny anymore but I would'nt spend too long trying to
convince the English on it insofar as the treatise of Huygens on the
Equation of Time and what it does sets the standard against which any
alternative view can be compared.

For goodness sake,what is it that makes people believe in an
astrological framework with a value for axial rotation through 360
degrees in 23 hours 56 minutes 04 seconds !!!,Does anybody here
understand that it is even below the level of creationist thinking or
rather,do they noit understand the basic transfer of the 24 hour day
to the axial cycle as a constant but not as an observance as the
solar/sidereal ficvtion has it -

This is not the first time you lot disgraced your nation,the King had
to intervene in the matter of Harrison's rightful resolution for
determination of longitudes using his clock (which of course involves
the Equation of Time principles) but now the situation is far,far
worse.I do not mind that you fraks betray your natiion,if you wish to
believe in the solar/sidereal fiction above then that is either
madness or eccentricity however that type of reasoning places an
incredible obstacle to productive work due to its astrological
foundations.
