The efficiency of the proposed device for controlling speed changes by means of a differential transmission with a closed hydraulic system via the solar gear, in the case where the driving link is the carrier and the driven one is the epicycle, appears as follows
These spurious effects, "dark energy", "dark matter", and "accelerating expansion", are reminiscent of Ptolemy's epicycles when an incorrect model of the solar system was forced to fit the data, rather than using the data to test different models of the solar system.
The exemption clause specified by infinity shades adds an ungraceful epicycle to the standard selection rule.
Barfield points out that "Greek and medieval astronomers were not at all disturbed by the fact that the same appearances could be saved by two or more quite different hypotheses, such as an eccentric or an epicycle, or, particular]y in the case of Venus and Mercury, by supposed revolution round the earth or supposed revolution round the sun.
73) As is well-known, Ptolemy proposes that a planet's motion may be represented geometrically either by an eccentric circle (falak kharij) possessing a center other than the earth's center; or, if the earth's center is to be retained, an epicycle (falak tadwir) must be added to the circumference of the deferent circle (falak hamil); or finally, some combination of eccentric and epicyclec circles could be employed.
14) Doing this will add another epicycle to the already doubly subjunctive response-dependence theory (being disposed to have a sentiment means being disposed to be disposed to feel an emotion).
Blake iconically alludes to Milton's lines on the mystery of the skies in the spiraling lines that wildly spread in circles across the plate of Milton 30/38, indicative of a Time-Space manifold--reflecting Book Eight of Paradise Lost (76-84), where the circling "Fabric of the Heav'ns" is "scribbl'd o'er, / Cycle and Epicycle, Orb in Orb," signifying the "quaint Opinions" of those that attempt to "frame" a "model" of the universe.
For the problem that had vexed many interpreters of Giordano Bruno is that in his Cena de le ceneri he maintains to possess the correct interpretation of the Copernican system through reading his diagram of che planets as though the earth and the moon formed an epicycle on a virtual orbit around the sun.
before protecting it, but that seems like an unnecessary epicycle.
Eventually, the pattern of epicycle adjustments became exceedingly complex, and the evidence against the Ptolemaic model became so overwhelming, that the Earth-centered Ptolemaic view was replaced by the sun-centered Copernican view.
7) Thapar points out that according to some scholars, the number 432,000 could be of Babylonian origin, combined with the Greek epicycle theory (15).
Calmeta manages, while blowing on his pipes, also to sing about the phases of the moon, its epicycle, equant, and deferant, the rules and attributes of the planets ("del rosseggiante Marte, del temperato Giove e del pigro Saturno" Filocolo 5.
Also, if we allow the center of the epicycle to move at a constant angular speed around a third point on the opposite side of the deferent, one can predict the positions of the planets much more accurately.
The scientist does not observe the system "perched on the epicycle of Mercury" (Skinner, 1974 p.
The correction applied to the mean motion in order to find the true position is represented by the planet's position on the epicycle (the true position may be ahead of or behind the center of the epicycle as shown in the mean position) and is called the motion in anomaly.
