« on: June 22, 2022, 10:17:45 AM »Yeah, I am wondering how you claim that something cannot be adjacent to the infinite.Chapters 1 & 2I find it amusing that you fail to point to a direct reference to Ptolemy when laying claim as to what he believed, instead relying on the hearsay of others "to speak the truth," "you can trust us, this is what Ptolemy believed."
After describing triangulation, as used by surveyors and on which the author is particularly keen, he introduces the astronomers Hipparchus of Nicaea, Claudius Ptolemy of Alexandria, Nicolas Copernicus, Tycho Brahe, Johannes Kepler and Galileo Galilei. As astronomers, their opinions and theories formed the standard views of astronomy in their times and Copernicus and Kepler especially laid the foundations of modern astronomy, but the author believes they all made a fundamental mistake: beginning at Hipparchus they all held that “the heavenly bodies (the stars) are infinitely distant.” (page 3)
The author never says where this saying is recorded; he only insists it was Hipparchus’s conviction and that the others accepted it at face value. We can’t check Hipparchus’s own writings, they’re lost; we mostly know them from Ptolemy. So, if Ptolemy, author of the standard text on geocentric astronomy used for 1400 years (the famous Almagest), built his theory of the universe while accepting this, you’d expect to find it in his writings, but you’d be disappointed – the Almagest doesn’t mention it. In fact, Ptolemy claims the stars are just beyond the orbit of Saturn, 20,000 earth radii from Earth (from Ptolemy’s Planetary Hypotheses, Hamm, 2011, p202).
Nah, doesn't fly.
Yet when Hickson claims a direct quote of Hipparchus (i.e., "the heavenly bodies are infinitely distant," you offer nothing more than a statement a direct quote of Hipparchus or his work would be impossible, because we cannot check Hipparchus' writings.
You know you do not have access to them.
That's all.
Spare us the rest of the writing as it is rendered totally useless by this demonstration of your bias.
This demonstration indicates an inability to assess the printed material on a toothpaste tube, let alone a written work by a scientist.
I do beg your pardon, how remiss of me.QuoteTherefore, the greatest distance of Saturn, which is adjacent to the sphere of the fixed stars, is 19,865 earth radii, and its least distance is 14,187 earth radii.
…
If all the diameters subtended the same apparent angle at their mean distances, the ratio of one diameter to another would equal the ratio of their distances, because the ratio of the circumferences of circles, as well as of similar arcs, one to another, is equal to the ratio of their radii. In the measure in which the diameter of the Sun is 1,210, the diameter of the Moon is 48; the diameter of Mercury 115 the diameter of Venus 622½; the diameter of Mars 5,040; the diameter of Jupiter 11,504; and the diameter of Saturn 17,026. The diameter of the first magnitude stars in this measure, assuming that their (sphere) is adjacent to the furthest distance of Saturn, is 19,865, or about 20,000; and the amount is surely not less than 20,000. But the diameters do not subtend equal angles, for the diameter of the Moon subtends an angle 1 1/3 times that of the Sun, and the diameters of the planets subtend angles smaller than the Sun in the ratios mentioned. It is clear that in the measure where the diameter of the Sun is 1,210, the diameter of the Moon is 64 because it is 1⅓ times 48; the diameter of Mercury is 8 because it is about 1/15 of 115; the diameter of Venus is 62 which is about of 622½; the diameter of Mars is 252 which is 1/20 of 5,040; the diameter of Jupiter is 959 which is about 1/12 of 11,504; the diameter of Saturn is 946 which is about 1/18 of 17,026; the diameters of the first magnitude stars is 1,000 which is 1/20 of 20,000, and they are certainly not smaller.

Now perhaps you know of where Hickson gets his quotation, with a direct citation or reference? In turn, I find it slightly amusing Kings Dethroned is accepted as the trustworthy work of a scientist.
Finite is adjacent to infinite.
So, Ptolemy made no claim resembling your analysis.
