One Thousand and One Conjectures

Guido of Arezzo's staff notation — the 11th-century invention that fixed pitches on lines rather than leaving them to memory-jogging squiggles — is here treated as an error-correcting code, and its effect on transmission is claimed to be discontinuous rather than gradual.…

Information theory meets Homer: the stock formulas of oral epic — the swift-footed heroes and wine-dark seas — are here interpreted as redundancy bits, the padding a noisy channel needs to protect its payload. In transmission over fallible human memory, the hard-to-recover…

Two transmission technologies for Sanskrit ran side by side for centuries: the mnemonic machinery of Vedic recitation — interlocking recitation modes and error-checking permutations built to preserve the Rigveda syllable-perfect — and ordinary manuscript copying, which carried texts like the Mahābhārata. Philologists…

The Byzantine empire ran a fire-signal chain that could relay news of Arab raids from the Cilician frontier to Constantinople within hours — a communication channel in the exact information-theoretic sense, and one operating under noise, since fog and haze could blind…

This joins medieval fiscal instruments to information theory. An Exchequer tally was a wooden stick notched with a debt's value and then split lengthwise, creditor and debtor each keeping half; the split's matching grain already authenticated the pair. The conjecture claims the…

Hebrew poets in al-Andalus wrote muwashshah-style strophic poems to fit existing Arabic melodies, often naming the model song in a heading. This conjecture claims the named tune functioned as a quality-control device with measurable force: poems whose headings cite a melodic model…

A potsherd is a fixed, curved, often small writing surface, and that geometry should discipline the text written on it: line lengths truncated at sherd width, and — the sharper effect — abbreviation and symbol rates rising to squeeze standard formulas into…

Javanese charters date themselves with what looks like absurd redundancy — a single day fixed by tithi, several concurrent week-cycles, the lunar mansion, and more, where one system would do. Join this to information theory: redundancy is exactly what error-detecting codes are…

Writing a Bantu language in Arabic script is lossy: the letters underdetermine Swahili's vowels and several consonants, so a prose sentence admits many readings. Verse repairs the channel: the fixed syllable counts and rhymes of the utendi forms constrain decoding, so meter…

Maya codices carry a phonetic-logographic script packed into block grids; Mixtec codices carry pictographic narrative on open, red-ruled pages read along a winding path. These are two engineering solutions to the same problem — putting court knowledge onto bark and hide —…

The Andean khipu — knotted cords encoding by knot type, knot position, cord color, and ply — and the Maya glyph block are the Americas' two great non-alphabetic information carriers, and they can be compared on equal terms with the plainest of…

A minority of catalogued khipus violate the standard decimal place-value knot grammar established for Inka accounting cords; whether these anomalous khipus are narrative, mnemonic, ritual, or something else remains contested. The structural conjecture sidesteps the decipherment fight entirely: if the anomalous class…

The Masoretes surrounded the biblical text with a lattice of counts and marginal notes — how many times a rare spelling occurs, which word marks a book's midpoint — that modern readers often treat as pious scholasticism. Functionally, it is error-detecting code:…

Marginal masoretic notes are not spread evenly over the biblical text; they thicken around rare spellings, look-alike sequences, and places where one verse could contaminate a near-twin. Copying errors are not spread evenly either — scribes slipped at characteristic traps like repeated…

The Homeric epics are built from formulas — prefabricated metrical phrases like 'swift-footed Achilles' — and their manuscript witnesses disagree with one another in thousands of places. The surprising connection is that the formula system itself was the variant factory: a line…

The Vedic padapatha (a word-by-word recitation kept beside the continuous samhita), the Masoretic apparatus around the Hebrew Bible, and the Qur'anic qira'at reading traditions are all famous as fidelity machines; information theory says any such machine is an error-correcting code, and every…

Many Dunhuang popular narratives carry a second layer of small user-added marks — punctuation dots, highlights, corrections. The surprising connection is that in performance texts this layer is a cueing system rather than a reading aid: a reciter who knows the patter…

Oral epic loves verbatim repetition — the messenger delivers the message in the very words we already heard — because for a listener repetition is structure, confirmation, and rest. For a reader it is redundancy, and the surprising connection is that written…
