Globe Deconstruction Review — a reference check on the paper behind the perspective argument: what it contains, who wrote it, and which of its evidence survives inspection.

Where this lands
The claim. At p. 127, beside the QR code numbered 42, the book says: “If you have any doubt that our vision is globular, read through this technical paper from Vortexpuppy (PhD in mathematics).” One paper, one named author, one credential.
The finding. The file is five documents concatenated. The six-page monograph the argument rests on has no author; Vortexpuppy is named on p. 46, over a different and better part. The monograph’s references are real and its experimental detail is not: light-emitting diodes, which date from 1962, in a 1902 and a 1913 experiment; a sub-pixel table at sensor rows up to 3,900 credited to a 1966 paper, three years before the image sensor existed.
The reference is genuine, and the data attributed to it is not.
What this licenses. One thing: the monograph’s empirical claims cannot be relied on. It licenses nothing about Miller, who cites the document rather than presenting it as his own; citing a bad source is an ordinary failure that no review of this length is immune to. Nor does it touch the physics response, kept on its own page so that it leans on nothing here: the paper’s own page 5 refutes the use it is put to, whoever wrote it.
The PDF restarts its internal page numbering five times. The parts share no typography, argument, sourcing conventions or failure modes, and treating them as one work flatters the weakest by association with the strongest.

The item cited as “the technical paper” is the six-page monograph at the front — paper 1, as the physics page calls it. The Euclidean treatise that follows is the better work: careful classical geometry, applied correctly and then extended past what it can carry, when results about how things appear become claims about what can be hidden — a step that is not in Euclid. The book may simply be describing the file by its one visible byline, but a reader following its sentence arrives at an unattributed document believing it has an author and a doctorate behind it.
The citation skeleton is genuine: Hillebrand 1902, Luneburg 1947, Brown 1966, Koenderink & van Doorn 1992, Pepperell and colleagues 2018, Hertzmann 2024 all exist and are real work in this area. What does not survive inspection is the experimental detail attached to them.
The text attributes the alley experiments — the classic visual-space test in which an observer in a dark room sets two rows of lights so that they look parallel — to “Franz Hillebrand (1902) and Steel Blumenfeld (1913).” Its own reference list gives “Blumenfeld, W.”, and the literature agrees: W. Blumenfeld, Untersuchungen über die scheinbare Grösse im Sehraume, Zeitschrift für Psychologie 65 (1913), 241–404, alongside F. Hillebrand (1902). The prose and the reference list of the same six pages disagree about a researcher’s name; the reference list is right.
The monograph describes the 1902 and 1913 alley apparatus as “24 point-source green LED lamps mounted on bilateral motorized transverse tracks”, with dimensions and a fixation rig quoted to two decimal places. Practical visible light-emitting diodes date from 1962, and green ones later still. The historical experiments used flames and rods. This matters beyond the anachronism: a quantitative result — a hyperbolic-cosine law for alley separation — is attributed to the same studies, and a description this far from the real apparatus cannot be relied on to have preserved a real number.
The natural reply is that the anachronism is cosmetic, because the alley experiments did find something real: settings that look parallel are not physically parallel, and Luneburg (1947) modelled visual space as hyperbolic to explain it. Both parts are true; the second is still argued, and Erkelens (2015), cited below, proposes a different geometry. But that is a result about judgments of parallelism across a few metres of dark room. Whether the monograph’s hyperbolic-cosine formula follows from the historical data we cannot say, since it is attached to measurements that were never made; and nothing in the alley literature concerns whether a distant object can be hidden below a horizon, the use the book puts it to.
The “empirical optical bench proof” presents a table of measured sub-pixel deflections at sensor rows running to 3,900 px, credited to Duane Brown’s 1966 lens-calibration work.
There was no image sensor in 1966. The charge-coupled device was invented at Bell Labs on 17 October 1969 — three years after the paper. The first experimental CCD, built in 1970, was an eight-bit linear array; the first two-dimensional imaging CCD, in 1971, was 100 × 100 pixels. A sensor with 3,900 rows is a device of the mid-2000s, roughly forty years downstream. A table of deflections indexed by sensor row and quoted to sub-pixel precision cannot have come from a 1966 publication by anyone.
That argument runs on the calendar alone, and Brown’s paper, read in full, settles the same point directly: a star-field calibration of two surveying cameras (phototheodolites) on glass plates measured by hand under a microscope, every error quoted in microns. The words pixel, sensor, digital, electronic and charge-coupled do not occur in its nineteen pages; neither of its two tables is indexed by position across a detector; and its subject is not the barrel and pincushion distortion the monograph names (straight lines bowing outward or inward) but the decentering residue, the few microns of error a slightly misaligned lens element adds (method notes). The paper is real and foundational — the Brown–Conrady model named for him is the standard treatment of lens distortion in camera calibration today — which is exactly what makes the citation persuasive.
No named author anywhere in the lead document. A “CONFIDENTIAL & PROPRIETARY — ACADEMIC RESEARCH MONOGRAPH” footer on a file distributed by public link. A section headed “The 10/10 Unassailable Physics”. A “Plain-English Translation” block after each equation. An abstract that says “definitively refutes”. Each is a style choice; with the three checked indicators they describe a document assembled around real references rather than written from them. One testable hypothesis fits — genuine citations carrying details that are not in them, and a paraphrase after each equation, are characteristic of machine-generated text — and it is named as a hypothesis only; nothing here establishes how the document was made, and nothing needs to.
A credit line can be loose without being false. If the monograph means only that its bench used Brown’s method, and the numbers are its own measurements on a modern camera, the anachronism does not bite as described. We think the plain reading of “empirical optical bench proof” attached to a named 1966 source is that the data comes from the source; on the looser reading the finding changes shape rather than disappearing, since the table would then have no stated apparatus, operator or date at all.
We identified no institution, which is not the same as none existing. The affiliation on the lead monograph returned nothing we could confirm; absence of a search result is weak evidence.
We are reading one distributed copy. The file’s embedded metadata gives an August 2026 creation date and a macOS PDF pipeline. If a different copy carries a byline, that changes the first finding.
Nineteen pages, nine figures, two tables (full citation under Sources). The experiment is a stellar calibration of a pair of Pth 60 phototheodolites, 600 mm focal length and 17° × 17° field, photographing the same star field side by side. The recording medium is given in one sentence:
“Kodak Microflat glass plates coated with 103 F emulsion were employed. The plates were photographically processed together and were measured on a calibrated Mann comparator by the same operator on different days.”
A Mann comparator is a hand-operated measuring microscope for plates. The plates were glass, 6 mm thick and 190 × 215 mm, wet-processed, then measured by hand: 155 star images per plate, two settings on each. The scale bars on the residual-vector figures read “0 5 10 microns”. Table 1 gives mean errors for the two cameras under three adjustment cases — six numbers; Table 2 gives two calibrated decentering parameters per camera. Neither is indexed by position across a detector or runs to thousands of rows. Brown’s first paragraph defines decentering as tangential distortion plus an asymmetric radial component and gives its scale: suppressing it physically “to a value not exceeding five microns over the plate format” takes “appreciable skill and patience” from the optical technician, and getting below two microns “calls for luck in addition to skill and patience.” Five microns across a 215 mm plate is two parts in a hundred thousand: the size of the phenomenon the deflection table is credited to.
