ACCORDING to Prof. Newcomb, for instance, the distance of the sun is about 380 times the distance of the moon — as determined by triangulation.(1) But upon page 22, Popular Astronomy, Newcomb tells of another demonstration, with strikingly different results — as determined by
A split god.
The god Triangulation is not one undivided deity.
The other method with strikingly different results is the method of Aristarchus. It cuts down the distance of the sun, from 380 to 20 times the distance of the moon. When an observer upon this earth sees the moon half-illuminated, the angle at the moon, between observer and sun, is a right angle; a third line between observer and sun completes a triangle. According to Aristarchus, the tilt of the third line includes an angle of 86 degrees, making the sun-earth line 20 times longer than the moon-earth line.
"In principle," says Newcomb, "the method is quite correct, and very ingenious, but it can not be applied in practice." He says that Aristarchus measured wrong; that the angle between the moon-earth line and the earth-sun line is almost 90 degrees and not 86 degrees. Then he says that the method can not be applied because no one can determine this angle that he said is of almost 90 degrees. He says a something that is so incongruous with the inflations of astronomers that they'd sizzle if their hypnotized readers could read and think at the same time. Newcomb says that the method of Aristarchus can not be applied because no astronomer can determine when the moon is half-illumined.(3)
We have had some experience.
Does anybody who has been through what we've been through suppose that there is a Prof. Keeler in the world who would not [65/66] declare that trigonometrically and spectroscopically
and micrometrically he had determined the exact moment and exasperating, or delightful, decimal of a moment of semi-illumination of the moon, were it not that, according to at least as
good a mathematician as he, determination based upon that demonstration does show that the sun
is only 20 times as far away as the moon?(4) But suppose we agree that this simple thing can not
Then instantly we think of some of the extravagant claims with which astronomers have stuffed supine credulities. Crawling in their unsightly confusion that sickens for simplification, is this
offense to harmony:
That astronomers can tell under which Crusade, or its decimalated moment, a shine left a star, but cannot tell when a shine reaches a line on the moon —
Glory and triumph and selectness and inflation — or that we shall have renown as evangelists, spreading the homely and wholesome doctrine of humility. Hollis, in Chats on Astronomy, tells us that the diameter of this earth, at the equator, is 41,851,160 feet.(5) But blessed be the meek,
we tell him. In the Observatory, 19-118, is published the determination, by the astronomer Brenner, of the time of rotation of Venus, as to which other astronomers differ by hundreds of days.(6) According to Brenner, the time is 23 hours, 57 minutes, and 7.5459 seconds. I do note that this especial refinement is a little too ethereal for the Editor of the Observatory: he hopes Brenner will pardon him, but is it necessary to carry out the finding to the fourth decimal place of a second? However, I do not mean to say that all astronomers are as refined as Brenner, for
instance. In the Jour. B.A.A., 1-382, Edwin Holmes, perhaps coarsely, expresses some views.(7)
He says that such "exactness" as Captain Noble's in writing that the diameter of Neptune is 38,133 miles and that of Uranus is 33,836 miles is bringing science into contempt, because very little is known of these planets; that according to Neison, these diameters are 27,000 miles and 28,500 miles. Macpherson, in A Century's Progress in Science, quotes Prof. Serviss: that the average parallax of a star, which is an ordinary astronomic quantity, is "about equal to the apparent distance between two pins, place one inch apart, and viewed from a distance of one hundred and [66/67] eighty miles."(8) Stick pins in a cushion, in New York — go to Saratoga and
look at them — be overwhelmed with the more than human powers of the scientifically anointed — or ask them when shines half the moon.
The moon's surface is irregular. I do not say that anybody with brains enough to know when he had half a shoe polished should know when the sun had half the moon shined.(9) I do say that if this simple thing can not be known, the crowings of astronomers as to enormously more difficult
determination are mere barnyard disturbances.
Triangulation that, according to his little priests, straddles orbits and on his apex wears a star — that he's a false Colossus; shrinking, at the touch of data, back from the stars, deflating below the sun and moon; stubbing down below the clouds of this earth, so that the different stories that he told to Aristarchus and to Newcomb are the conflicting vainglories of an earth-tied squatter —
The blow that crumples a god:
That, by triangulation, there is not an astronomer in the world who can tell the distance of a thing only five miles away.
Humboldt, Cosmos, 5-138:(10)
Height of Mauna Loa: 18,410 feet, according to Cook; 16,611, according to Marchand; 13,761, according to Wilkes — according to triangulation.
In the Scientific American, 119-31, a mountain climber calls the Editor to account for having
written that Mt. Everest is 29,002 feet high.(11) He says that, in his experience, there is always an
error of at least ten per cent, in calculating the height of a mountain, so that all that can be said is that Mt. Everest is between 26,100 and 31,900 feet high. In the Scientific American, 102-183,
and 319, Miss Annie Peck cites two measurements of a mountain in India: they differ by 4000 feet.(12)
The most effective way of treating this subject is to find a list of measurements of a mountain's height before the mountain was climbed, and compare with the barometric determination, when the mountain was climbed. For a list of 8 measurements, by triangulation, of the height of Mt. St. Elias, see the Alpine Journal, 22-150: they vary from 12,672 to 19,500 feet.(13) D'Abruzzi [67/68] climbed Mt. St. Elias, Aug. 1, 1897. See a paper in the Alpine Journal, 19-125.(14) D'Abruzzi barometric determination — 18,092 feet.
Suppose that, in measuring, by triangulation, the distance of anything five miles away, the error is, say, ten per cent. But, as to anything ten miles away, there is no knowing what the error would
be. By triangulation, the moon has been "found" to be 240,000 miles away. It may be 240 miles or 240,000,000 miles away.(15)

3. "During the seventeenth century the eclipse method for determining the distance and parallax of the Sun fell from favor owing to its inherent inaccuracy. For a brief period, the lunar dichotomy method was revived and applied with the help of the telescope. Determining the exact moment of dichotomy was not, however, made easier by the telescope; if anything, it became more difficult. Furthermore, like the eclipse method, the lunar dichotomy method is inherently inaccurate, for a small error in measurement results in a much larger error in the final result. Albert Van Helden.

Contrary to Brenner's determination of a rapid rotational period of Venus in 1895 by means of observations of its surface markings, V. Cerulli had determined in the same year a rotation period of 224.7 days from the linear markings
he observed on Venus, (similar to those observed on Mars by Schiaparelli and Lowell), in the same year. V. Cerulli. "Le ombre di Venere." Astronomische Nachrichten, no. 3310, 365-8.
According to Lowell: "Mercury and Venus rotate once on their axes in a revolution around the sun." "Mittheilungen vom Lowell Observatory, Flagstaff, Arizona." Astronomische Nachrichten, no. 3384, 423-4. Jean Domenique Cassini had previously claimed a rotational period of 23 hours and 21 minutes, based upon a bright spot and several dusky spots that he had traced upon the planet in April of 1667. In 1726 and 1727, Bianchini was able to draw a map of the three oceans
and two spots on Venus; but, as stated by Webb, he "gave a wrong rotation of 24d 8h." Watching
the cusps, Schröter also obtained a rotation period of 23 hours 21 minutes, between 1788 and 1793; and, in 1842, De Vico refined this measure to 23 hours 21 minutes 22 seconds, after rediscovering and observing a series of markings, or spots, which had first been discovered by Bianchini, (which Webb says were "found, save in the omission of one one small spot, remarkably exact"), which were measured 11,800 times by his assistant Palomba.

7. Edwin Holmes. "Accuracy or inaccuracy." Journal of the British Astronomical Association, 1, 382-5. Correct quote: "...extreme accuracy." The modern measures given for the diameters of Uranus and Neptune are 31,567 miles (50,800 kilometers) and 30,200 miles (48,600 kilometers), respectively. Halley also displayed such traits in A Synopsis of the Astronomy of Comets: "Times of perihelion passage are quoted to the nearest minutes when they are at most accurate to the nearest 120 minutes. Halley happily quotes perihelion distances to an accuracy of about 1 part in 50,000 — when he is working at best only to an accuracy of 1 in 700! It is obvious that Halley enjoyed using six-figure logarithms and did not like losing figures when quoting his results, even when these figures were far from significant. David W. Hughes.
