A few things I’m working on.

I’m QING. I work with mathematical structures, models, and small tools. This is where I keep what I find.

Q₄ / A change of view4D → 2D

Move the slider, or focus it and use the arrow keys. This changes a rotation in four dimensions before the shape is projected onto this flat screen.

16 vertices. 32 edges. Crossings in this view do not add connections. Every vertex always has four neighbours.

An illustration of a four-dimensional hypercube, separate from the research below. No automatic movement.

Research notebooks.

01 / Research notebook

Menger Sponge × Hypercube

Constructions, counterexamples, and a change of metric: can another coordinate system preserve every shortest-path distance?

Twenty retained cubes of a first-stage Menger sponge beside its face-adjacency graph; four edges are highlighted in gold.Enlarge ↗
Twenty retained cubes, and the graph of their face-to-face connections.

Bladeless Turbine

A small mathematical study of when a disc turbine can start, and how resistance limits useful power.

Cutaway illustration of a nine-disc turbine assembly with a shaft, bearings, housing, and blue flow-direction lines.Enlarge ↗
A disc turbine opened up: disc gaps, shaft, bearings and a suggested flow path.

Metal Growth, Two Causes

The same increase in metal mass can hide very different balances of deposition and dissolution.

An intricate gold-coloured metallic tree with visible roots and fine branches inside a sectioned transparent glass vessel.Enlarge ↗
Concept illustration inspired by Newton’s notes on metallic trees and vegetation in glass, Dibner MS 1031 B, f.1r. The gold colour, tree geometry and vessel are artistic choices, not an experiment reconstruction or evidence of making gold.

Quantum Eraser

Why interference can appear in selected groups while the combined detection probability stays unchanged.

Read the full research ↗
A path-polarization interferometer with H and V arm markers, a diagonal marker analyzer, two conditional fringe curves, and a constant unsorted marginal.Enlarge ↗
Ideal model: p=q=1/2 and coherence η=1. The two marker-conditioned probabilities have opposite fringes; their equally weighted total is 1/2. Both output ports must be retained for normalization. The instrument layout is conceptual and the traces are analytic, not measurements.
QING in blue and gold, with misty mountains, a moon and still water. Texts to explore, not answers to accept.
Warm yellow commission notice with a study folio and geometric drawing. Complete service text follows.
