Inaccurate to say the least.In Maxwell's era they were already faced with the dilemma that these relativistic jokers say only surfaced in the early 20th century.Newton had already rejected the aether due to the influence of Roemer's insight and fell back on the geometric descriptions left by Kepler.The failure came later in attributing aether back into the Newtonian agenda and the dilemma of having the Sun attracting the Earth without an intermediary fluid while having the Sun illuminate the Earth with a medium. http://www.bodley.ox.ac.uk/cgi-bin/ilej/image1.pl?item=page&seq=9&size=1&id=bm.1843.10.x.54.336.x.425 Maxwell would have known the arguments but who was going to challenge Newton's legacy barely 100 years after Newton's disciples carved out an idealism which was more political than any seen before.

You all appear to watch the straws float by and not dive for the pearls.Feynman has Roemer having confidence in Newton's gravitation laws even though Roemer's insight has no gravitational elements and was discovered decades before the Principia.It is like watching a puppet show where historical characters and their insights can be moved like pushing equations around the page.

This is just warmed over Bacon.Start with doubts,do experiments and remove all the doubts and you are left with certainty,works for a while but this is where Newton failed.Elliptical planetary motion would be conditioned by a larger rotation of the solar system about the Milky Way axis,Newton treated the solar system as an isolated system and conditioned all planetary motion to the attraction of the Sun and the influences of planets on each other.Unfortunately he created the sidereal universe to frame it in and reviewing the 1844 text reaffirms this.They still think that day follows night because the Sun rises when the Copernican insight is that the Earth rotates out of its orbital shadow and you wonder why they found themselves in a dilemma. > As an example I would mention Newton's equations.

Making things go faster and imagining things would be different was a desperate attempt to break the Newtonian mold,it would just be easier to step up to galactic rotation and its axis and determine that influence on the solar system and planetary motion.Too late !,1923 and the damage was done.

No,much simpler than that and back to basics.Astronomers noted retrograde motion of Mars as seen from Earth and remedied the situation by using the Sun as a focal point to descriminate the orbital motion of the Earth from the orbital motion of Mars,retrograde motion being a product of comparative orbital motions rather than any mean distance from the Sun. As the sidereal format is a product of Flamsteed from 1677,the previous astronomers would have used the Equation of Time correction without any 'time' correspondence between Mars and the background stars.Astronomers became cataloguers after Flamsteed which is partly the reason no objection was raised to Newton's formulations based on Roemer's actual use of the Equation of Time and Flamsteed's erroneous stellar circumpolar/axial rotational equivalency. http://www.astro.wisc.edu/astro104/Copernicus_Mars.gif > On the other hand, as I already said, the phenomenological conception > without mathematics is doomed.

Do experiments all you wish but foisting them on celestial observation as predictions without taking into account how rotations generate illusions is quite a feat,it is just chanting the same mantra as the supposed opposition.Mathematics in the wrong hands burns all ahead of it and nobody but nobody will ever say otherwise even when it is advantageous to leave astronomical concerns aside.You have cataloguers who call themselves astronomers when their association is more akin to astrology with its attendent celestial sphere structure and the constellations which are a product of men's imagination,basically image collectors for theorists and I have to watch as the great astronomers and their insights are dragged into the mess.
