The canonical spine of [[Physics]]: the full tree-verified child structure of the discipline that studies [[Matter|matter]], [[Motion|motion]], [[Energy|energy]], [[Space|space]] and [[Time|time]], running from [[Classical_mechanics|classical mechanics]] and [[Thermodynamics|thermodynamics]] through [[Electromagnetism|electromagnetism]], [[Optics|optics]] and [[Acoustics|acoustics]] to [[Quantum_mechanics|quantum mechanics]], [[General_relativity|general relativity]], [[Condensed_matter_physics|condensed matter]], [[Particle_physics|particle physics]] and [[Physical_cosmology|cosmology]]. Every entry below is a child of this hub's live Wikipedia article, publishable to Obsidian as the scaffold for route objects (microsims, songs, semiotics, cardsets, games, streams, transcripts) keyed to this hub.

> **Permissions to request up front (house rule, MTN 2026-09-22).** Any agent that works this page — its spine, the worklists at its foot, or its shard — states before its first tool call every permission the run will need and asks for all of them in one round: (1) browser-pane site access, scope *site*: en.wikipedia.org (title and oldid verification), wikitube-3d-microsims.netlify.app (200-checks of players), cdn.jsdelivr.net (library pins), and gutenberg.org / archive.org / ntrs.nasa.gov only if a book is re-fetched; (2) folder access to the vault root (`en.wikitube.io/`) and, for a deploy pass, to `_3d_deploy_stage/`; (3) no `WT!` authorization is needed for this page — it is an ordinary portal — but touching `WT!Space_Mining_In_Minnesota` or its `PORTAL_WT!` page needs MTN's (WIKI_RULES §1, §11); (4) no delete permission — everything here is append-only; (5) production deploy is MTN's: the run stages into `_3d_deploy_stage/<set>/` and hands over the deploy script. Nothing else.
**Physics in service of the apex.** Orbits and gravity, the rotating frame, the inverse-square and fourth-power laws, and the electromagnetism that runs the magnets, the coils and the cells — in service of Space Mining in Minnesota. This second spine sits beside the page's own: thirty sections chosen for what they supply to [[WT!Space_Mining_In_Minnesota]], one three.js microsim per section, and a hero — **The Joule Line**, an instance of the Master Portal Hero — with the two worklists at the foot. Apex: [[PORTAL_WT!Space_Mining_In_Minnesota]] · hub: [[PORTAL_Centers_of_Excellence]]. Files of this spine: plan `_registry/plans/PHYSICS_IN_SERVICE_SECTIONS.md` (beside the page's own `PHYSICS_SECTIONS.md`), shard `Style Guide and Worklist/PORTAL_Physics.worklist.md`, record `Style Guide and Worklist/worklists/PORTAL_Physics/jobs.json`, pack `specs/portals/PORTAL_Physics.pack.json`, set `physics/`.

*The Joule Line (PHY-HERO, `physics/Joule_Line.html`, built and gated SHIP 2026-09-22, 43 URL states walked headless with an empty console; the player goes live with MTN's next production publish): one noon hour of sunlight walked through collect, convert, store, transmit, work, radiate, account on six surfaces. Every section below is a stage or a component of it, and a child article embeds the hero locked on its own state (`?body=<id>&stage=<id>&embed=1`) until its section sim ships.*

### Notes (in service)
1. **What this page is.** The Physics spine *in service of* [[PORTAL_WT!Space_Mining_In_Minnesota]]: thirty sections chosen for what they supply to the apex, each with its Main article, its See-also children, a one-line sim brief with the equation the sim runs and the apex sections it serves. It is a skeletal outline by design (MTN, 2026-09-22): less advanced models populate the child articles and their sims from the two worklists at the foot, with the hero as the model of the house pattern.
2. **Slugs.** Every article slug is the exact current English Wikipedia title, resolved through the API on 2026-09-22 (redirects followed to their targets, disambiguation and non-existent titles dropped before the spine was fixed); `rev:` on every worklist row pins the revision.
3. **Build state.** The hero `physics/Joule_Line.html` is built and gated SHIP (rendered, zero console, sweep clean, 11 draw calls; `tools/gate.sh`, 2026-09-22) and its 43 URL states were walked headless; it is staged, not deployed — production is MTN's (style guide §12.10: a player replaces a placeholder only after a 200-check). Of the thirty section sims, 9 reuse a player a portal page already carries (Newton's_law_of_universal_gravitation on Physics, Kepler's_laws_of_planetary_motion on Physics, Conservation_of_energy on Physics, Momentum on Physics, Friction on Engineering, Black-body_radiation on Physics, Heat_transfer on Engineering, Faraday's_law_of_induction on Physics, Lorentz_force on Physics), 0 reuse the apex spine's (none), and the other 21 are queued as specs of their own.
4. **One article, several portals.** A section whose Main article is also an apex Main article is a *reuse* row: the apex owns the article and the sim, this portal adds membership (shared contract §1); the same holds for See-also titles the apex already carries. Available reads 0 on this page for the same reason as on the apex: nothing is verified live yet.
5. **Append-only.** This block was appended to the existing `PORTAL_Physics` page on 2026-09-22 under its own markers; nothing above the markers was edited. The in-service spine is a second spine on the page, not a replacement of the first.
6. **Worklist mechanics.** Rows are claimed, heart-beaten and closed only through the queue tool on the shard (`Style Guide and Worklist/PORTAL_Physics.worklist.md`); a row turns ✅ only with a live URL. The two lists here, the shard and `worklists/PORTAL_Physics/jobs.json` are projections of one record, regenerated together by `build_portals9.py` (kept with the item-9 checkpoint).

## Microsim libraries and worklists
Coverage: complete within declared bounds — the 30 sections and 93 See-also associations of this portal's spine (123 distinct titles), not a crawl of Wikipedia. Examined: every title against the English Wikipedia API on 2026-09-22 (redirects followed, missing and disambiguation titles dropped before the spine was fixed), the apex spine's rows (for shared articles), the three existing portal pages (for players already carried), the framework's `specs/sims/` (the hero built) and the run's book shelf. Pending/failed: the live 200-check of the hero and of the existing players is not performed — production deploy is MTN's and the sim host was not in this run's approved browser-pane sites (item 10). Last evaluated: 2026-09-22 (this run). Stopping rule: the spine's rows; no title outside them was scored.
Published assets and pending work are counted separately. Unknown coverage is not zero opportunity.

## Microsim Worklist
> **Permissions to request up front:** see the block at the head of this page — ask for all of them in one round before the first tool call (browser-pane sites, vault folder, no WT! scope needed here, no deletes, deploy is MTN's).
Row grammar (style guide §11.1): ``- [ ] [[Slug]] — engine · pattern · `equation` · what the viewer does · id · prio · type · rev``. Lifecycle markers (§11.2) are appended, never edited into the row. `type:` is `hero` (the Master Portal Hero instance), `section sim` (a spec of its own in `specs/sims/`, set `physics/`), `existing sim` (a player one of the portal pages already carries — the row names which — to re-verify), `reuse` (a section whose article and sim belong to the apex spine `WT!Space_Mining_In_Minnesota` — this portal adds membership, never a second build), `variant` (a See-also article's sim, `extends` the section's spec) and, on the Computation page, `brief` (a reviewer-sourced brief with book locators). `serves:SMM n` names the apex sections the row is in service of. The canonical record is `worklists/PORTAL_Physics/jobs.json`; this list and the shard `Style Guide and Worklist/PORTAL_Physics.worklist.md` are projections of it, regenerated together by `build_portals9.py`.

## Article Worklist
> **Permissions to request up front:** see the block at the head of this page — ask for all of them in one round before the first tool call (browser-pane sites, vault folder, no WT! scope needed here, no deletes, deploy is MTN's).
Row grammar: `- [ ] [[Slug]] — action · vault state · rev (bytes) · sim · id · prio · type`. `action` is `mint` (no page in `wiki/` on the 2026-09-22 scan of the vault), `densify` (a page exists below wt-article density: bring it up, append-only), or `place` (a dense page exists, or the article is owned by the apex spine: add this portal's membership and the sim by generator block, no rewrite). Every article follows style guide §2–§6 and §13: slug = the verified Wikipedia title, `oldid` pinned to `rev:`, the H2 skeleton mirrored from that revision, a lead that defines in bold and names the microsim, every figure footnoted to the shelf, a `Wikipedia : Wikitube` section, and a registry row. `WT!` pages sit outside this list.
