I am left, then, with this question of how many more epicycles will it take before the larger academic community recognizes that the earth is turning, and that such turning accounts for the spread of light across the land.

They were simply pessimists who couldn't imagine that anything as obviously complex as epicycles could be dramatically simplified with a simple model of planetary orbits.

Ptolemaic astronomy went on adding planetary epicycles to remove discrepancies; defenders of the phlogiston theory were driven to postulate negative chemical weights in order to maintain their paradigm.

As inflation caught on, however, some cosmologists grumbled about epicycles.

Most common people never even thought about it at all (not remotly relevant to farming or smithing etc.) The geocentric theory was actually mathematically «proven» by Ptolemy of Egypt, so belief in geocentrism was acceptable (it used epicycles where planets would make loops and such.

Trying to describe how the five planets in the night sky followed seemingly irregular paths, Ptolemy hit upon an idea he called epicycles.

There are observations that you could only understand by tinkering carefully with the theory; it sort of begins to look like [Ptolemaic] epicycles and I don't find it as attractive as the original simple picture, but that's a possibility.

According to Michael Wright, a former curator at London's Science Museum who has studied the mechanism longer than anyone, it modeled epicycles with trains of small gears riding around larger ones.

reminiscent of the medieval theologians arguments about how many angels could dance on the head of a pin... or the ever more complicated epicycles of the ptolemaic astronomers....

You're proposing new and ever - more elaborate epicycles as an alternative.

Seriously, isn't all this work on aerosols roughly equivalent to trying to plug in yet more epicycles to make the Ptolemaic model of the universe continue to work?

When observations failed to disclose such circular orbits, they retained their notions of essential order by supposing that the movements could be analyzed in terms of the Ptolemaic epicycles, i.e., circles on top of circles.

it reminds me of the epicycles and other complications used to explain the movement of the planets.

An epicycle in the arguments for the Alternative Vote in the coming UK referendum, it permits you to only vote once just like now!

He insisted that planetary orbits were circular (modified by secondary circles, the epicycles).

Closer examination showed that this didn't quite explain observations either, so the theorists added epicycles on top of epicycles until the model did work.

When Ptolemaic theorists discovered that the planets did not appear to be moving in a simple pattern around Earth, they added epicycles — tiny circular movements on top of the grand orbital circles.

Suddenly, planetary motions made sense without the complexity of epicycles, and the old theory was dropped.

Smolin and Woit believe that its recent absorption into a richer conjecture called M - theory has turned the former beauty of strings into mathematical structures as ugly as the epicycles Ptolemy invented to explain the orbits of planets as they circle the earth.

When you look at it this way, Primack's dismissal begins to sound rather like «Go away and let me work on my epicycles.

After all, the ancient geocentric universe of Ptolemy was able to account for the observed motion of the sun, moon and planets by using the complicated motion of epicycles — circles embedded within circles.

Among the data, he noticed something that startled him: Nothing supported the epicycle hypothesis.

That's what people wondered about is, you know, maybe, are we getting into some level of, you know, the epicycles, wheels within wheels within wheels; is there some other explanation that maybe makes more sense.

The Greeks explained this motion with «epicycles»: small circles superimposed on a larger orbit.

Ptolemy's ancient elaborate system of «epicycles» — a brilliant design to map out the heavens — falls just short, placing the earth at its center.

The sound work is Robert Huber's 2017 realization of the late Greek composer Jani Christou's Epicycle (1968), and the fact that it remains separate from the original is important here.
