84-to-2 Dimensionality Collapse (Hacı Osman)
A system's death is not an instantaneous silence but a progressive mathematical collapse of its dimensions, mirroring how optimizing algorithms inevitably strip away high-complexity, low-frequency variants.
Dimensionality reduction flattens 84 Ubykh acoustic waveforms into smooth marble slabs. · motion: Progressive collapsing of complex waveform ridges into perfectly flat planes.
wall text
Before dying in 1992 as the last speaker of Ubykh, Tevfik Esenç recorded the language's extraordinary phonology: 84 distinct consonants mapped against just two phonemic vowels. This installation transposes Georges Dumézil's archival field recordings into an 84-dimensional vector space. Through principal component analysis (PCA) and eigenvalue thresholding, the lowest-variance acoustic features—the hyper-rare pharyngealized ejectives—are systematically stripped away. The resulting dimensional attrition is milled into concentric marble stelae surrounding Esenç's grave. As the PCA truncation deepens, the complex CNC waveforms physically erode into featureless flat planes, framing linguistic extinction not as sudden silence, but as algorithmic optimization.

anchor facts used
- Tevfik Esenç, the last native speaker of Ubykh, died on October 7, 1992, and is buried in Hacı Osman village.
- The Ubykh language possessed an extreme phonological inventory consisting of 84 distinct consonants and only 2 phonemic vowels.
- French linguist Georges Dumézil made extensive baseline magnetic tape recordings of Esenç to preserve the phonetic data before his death.
mechanism
- High-Dimensional Vector Space Embedding — Digitizing Georges Dumézil’s field tapes of Tevfik Esenç and mapping the acoustic spectrograms of all 84 distinct Ubykh consonants into a continuous 84-dimensional feature space.
1. Data Ingestion and Embedding - Covariance Matrix Computation — Calculating the acoustic variance across Esenç’s continuous speech to quantify the statistical distance between the hyper-rare pharyngealized ejectives and the two dominant phonemic vowels.
2. Variance Quantification - Eigenvalue Thresholding / Truncation (PCA) — Systematically dropping eigenvectors with the lowest variance, mathematically erasing the most delicate, complex consonants first, and projecting the speech data into progressively lower dimensions until only the two vowels remain.
3. Algorithmic Erasure - CNC Subtractive Milling — Translating the structurally flattened, dimensionality-reduced acoustic data into G-code to mill 84 physical marble stelae, each exhibiting progressively smoother surfaces as phonetic data is lost.
4. Forensic Materialization

curatorial qa (machine verdict, unedited)
SCORE 4/5 after 2 attempt(s)
READS: The concentric marble blocks surrounding Tevfik Esenç's gravestone visibly flatten their milled acoustic waveforms into smooth planes, clearly demonstrating the progressive loss of dimensional complexity.
FAILS: The direct mathematical correspondence between specific Ubykh phonetic classes (pharyngealized ejectives down to two vowels) and individual stone coordinates requires the external PCA ledger to be understood.
