## MicroSim spec
### Parameters (tunable controls)
- `Ring radius` · 50–250 · radius of the rotating habitat (m, scaled)
- `Spin rate` · 0–5 · angular velocity setting artificial gravity
- `Test mass` · 0–10 · object whose centrifugal weight is shown
### What animates
A rotating ring spins and a test mass presses against the outer rim under centrifugal force.
### Learning objective
Show how a habitat's spin rate and radius set the artificial gravity felt inside.

## Concept summary
The Stanford torus is a proposed NASA design for a space settlement capable of housing 10,000 permanent residents. It is a type of rotating wheel space station, consisting of a ring with a diameter of about 1.8 km (1.1 mi), its rotation providing about 1.0 g of artificial gravity.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to Systems Engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Stanford torus
const ARTICLE = "Stanford_torus";
let p1, p2, p3;
function setup() {
createCanvas(720, 520);
pixelDensity(2);
// physics-dynamics sim — create the three sliders described above:
// Ring radius (50–250), Spin rate (0–5), Test mass (0–10).
// TODO: build labelled sliders in the control region (below the drawing region).
}
function draw() {
background(248);
// TODO: read p1/p2/p3; render the physics-dynamics in the drawing region and respond live.
// TODO: HUD — title + en.wikitube.io/wiki/Stanford_torus + control hints + live readouts.
}
```
