A Sampling of its Most …. Unusual Discoveries

the Premier Astronomy-History Journal

And challenging said premiership to compile a catalog of DIO-Generated Mis-Scholarship Even 1/10 as Extensive.

The Catalog:

1981: ** JHA** review
(by N.Swerdlow) misunderstands purpose —
even the unambiguous TITLE — of the book being reviewed.

Consistency.

1981: Swerdlow misunderstands significance of
statistical results achieved when data do not permit desired precision
but do establish a lack of demonstrated inconsistency with theory.

** DIO 1.1** [1991]

1981: Debut of
MacArthur-genius-to-be N.Swerdlow's
ineducability
(** DIO 20** [2012]
‡2 §B [pp.7-9])
regarding the potential accuracy of ancient solstices,
as he supposes equinoxes to be more accurate.

in the

S.Solstice accuracy within ordmag 1h was achieved by Kallippos & Hipparchos:

But Hoskin has never forgiven DR for the Longstreetian crime of being right. (

by confusedly-mixing epoch 1950.0 and epoch-of-date orbits

1987: James Evans
climb-assisted his way to
his current Editorship of the ** JHA** by publishing
a massive two-part 64pp alibi-fest (both sections run as Pb papers)
attempting to obscure the success of Ptolemy skeptics R.Newton & DR.
Among other contributions, the paper showed
how to acquire admiration for one's writing style, by publishing
without quotation-marks a couple of passages from J.Dreyer's 1890 book.

1987: Putative referees for the paper let pass the ** JHA**'s
pioneering abbreviation “Sag” for the constellation Sagittarius,
which actual astronomers abbreviate “Sgr”.

1987: The Evans paper tries
to alibi Ptolemy's lack of low stars
by pointing to Tycho missing some dim low summer stars,
unaware of
the fact that in summer it doesn't get completely dark in Denmark.

** DIO 2.1** [1992]
‡4 §F2 [pp.43-44].

1987: An even more imaginative alibi
suggests that there might have been
a 6°-high pile of rocks south of the alleged *observatory*
of Ptolemy (who astronomers have known for centuries wasn't an observer).
The Magnitude-Split test shows
that the rocks were entirely in the ** JHA**'s head.

1987: Same Evans paper tries showing how dumb
Ptolemy-skeptics are, since they allegedly over-estimate
ancient observational accuracy. To make his point, Evans adduces his own
1981 observations of the eclipsed Moon vs the star λSgr
and Hipparchos' two discordant 2nd-century-BC
observations of Spica, all of which displayed errors of ordmag 1°.
But DR showed that the Hipparchan incompatibility was not from
errors of observation but of wrong-signed parallax-correction: when this muff
is corrected, both Spica cases' errors drop from ordmag 1° to ordmag 1',
and same for Hipparchos' −140/1/27 Regulus observation,
likewise that of Evans' own 1981 bungled math,
when his identically wrong-signed parallax-correction is set straight.

** DIO 1.3** [1991]
n.288 [p.173];

1987: While trying to evade DR's
unevadable absent-error-waves proof
that Ptolemy stole the Ancient Star Catalog, the ** JHA**
sloughed over a huge 63° phase-difference that gutted its argument,
just saying that the phase is “not exactly right”.

1987: Same paper's unplumbed opacity-formula
turns out to demand that Tycho observed 8th magnitude stars.

This farce occurred because the author neglected to compute
post-extinction magnitudes by his own formula.

** DIO 2.1** [1992]
‡4 §H7 [pp.47-49].

1987: Weirder yet, the paper claims that star ζCMa
would be visible from Bergen, though at 10th magnitude by the paper's
own formula.

** DIO 2.1** [1992]
‡4 n.65 [p.48];

1987: The same paper's preferred atm opacity
produces 11 magnitudes of brightness-loss at the horizon.
Ptolemy says he observed 1st magnitude stars there.

[*Planetary Hypotheses* 1.2.6. See sardonic discussion at

§L8 and n.93.]

Thus, the

1989: Fabricated positions of Venus are
called (by Noel Swerdlow) “required” positions.
No one is *required* to fake data.

** DIO 11.3** [2002]
‡6 n.20 [p.74].

1989: Eyepopping
allegation in Swerdlow's Ptolemy-alibifest MacArthur-Award paper
that since (near maximum) Venus' elongation changes only
1°/12 in 6d, “in no way could Ptolemy estimate the time” of
greatest elongation, an astoundingly irrelevant (and laughably
misunderstood) point
upon which ** JHA** Board-member Swerdlow persists
in ignorance. Here, his delusion is used to try alibiing
the hilarity that Ptolemy self-contradictorily gives
(at

[How seriously the history-of-astronomy clique should be taken could not possibly be more ironically gauged than by the spectacle that its awe of brain-kissing expertise would lead it to recommend its grandest MacArthur for a completely straight-faced (and incompetent [not a word

Swerdlow's face must still hurt from the strain of not guffawing out loud at Ptolemy, the

1989: The misunderstanding
essential to this ** MacArthur Award**-winning paper's
claim that minuscule motion in 6d proves
Ptolemy couldn't determine the time of Venus' elongation is
depressingly parallel to the author's prior ironically-arrogant ignorance
of the method of equal altitudes:

Consistency.

In both cases, one simply measures two equal values of elongation at sufficient distance from maximum — one before, the other after — for accuracy (but not so great as to cause trouble from non-quadraticity) and take the two times' mean as the time of maximum.

(They teach this stuff in high school.

But not, apparently, at the institutions that voted a MacArthur to this artfully careerist paper.)

1989: The foregoing incomprehensions lead to
Swerdlow's claim (to alibi Ptolemy's fakes):
“the selection of a particular date for true greatest elongation
would be arbitrary in any case.” I.e.,
the ** JHA**, which makes up behind-the-back
fantastic smears at will, naturally
isn't bothered if a scientist just makes up data the same way.

1991: ** JHA** discovers the Winter Equinox.

Paralleling an equally eminent Muffioso's discovery of the Autumnal Solstice.

Both discoveries compared in magnificence to Winnie-the-Pooh's discovery of the East Pole of the Earth:

1991: New-arithmetic 128° − 65° = 65°.

(This is not a mere typo, as contingent math shows.)

** DIO 1.2** [1991]
§§G7&G9 [pp.121-122].

1991: Equating 67d2/3 with 67°2/3
(which is consistent with Velikovsky's 360d year:

unfittable by orbits, though these data
obviously can be described by the usual elements.

At Curtis Wilson's behest, the

weights are needed for measuring the great-circle size
of celestial longitude differentials.

0°.2 great-circle waves in the Ancient Star Catalog
would be undetectable.

1992: Same paper eyeballs fit to Peters longitude-error curve
(instead of using least-squares), with seriously false result.

** DIO 2.3** [1992]

1992: In so doing, the author forgets to remove
the large 11'-amplitude error-wave due to Ptolemy's known false obliquity,
which muddles the phase and amplitude
of the error-wave that actually needs explaining.

thus omitting the heart of the theory.

eclipse calculations (from his era back to 747BC)
with a non-existent 600y cycle.

** DIO 6** [1996]
‡1 §K [pp.26-27].

2001: In a last-ditch attempt
to salvage Ptolemy's claim of observership of the Ancient Star Catalog,
** JHA** again extensively attacked DR's
1982 paper (published in a refereed science journal)
proving Hipparchos observed the Catalog through a statistical argument
dependent upon assuming a clear atmosphere.

Highly expert analyses by K.Pickering and D.Duke ended this chauvinist nonsense quickly.

modern skies' daylight-sky opacity to ancient night-time best-clarity skies.
The

(In 2005, the 2001 author rather switched over to Hipparchos' side. In 2013, he sorta switched to the middle, still unable to admit having prominently and slanderously taken the wrong side in this ex-debate.)

2001: The most obvious factor overlooked by
the ** JHA** attack (and everyone else) was that
if ancient sky-opacity (not long-suspected plagiarism) had accounted for
the unique 6° gap between Ptolemy's horizon and his lowest stars,
then we would find a similar gap in Hipparchos'

2001: As part of his argument for dense sky-opacity,
the paper's author argued
(along with the whole history of astronomy establishment)
that Ptolemy's *arcus visionis* data were not on the horizon,
despite Ptolemy's statement and diagram claiming they were.
** DIO** challenged this in correspondence, pointing out
that Ptolemy's opposite data, acronychal risings,
cannot even be defined other than on the horizon. These unambiguous data
proved the existence of a clear ancient atmosphere
(which thereby requires [from atm-opacity consistency]
that Ptolemy's

Actually it's about 1/4 of a magnitude — an error of 10%.

2013: The same article provides (p.73) a formula for atmospheric refraction as a function of true zenith distance which is actually a function of apparent zenith distance. At the horizon this formula (and the author's odd atmospheric opacity) will predict a star to be 40 times too dim. Error = 4000%.
