THE FINE-STRUCTURE CARD — the LSC-1 face
THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE FINE-STRUCTURE CARD · how strongly light and matter hold

WAKES WHEN someone asks about 1/137, the strength of electromagnetism, or hydrogen's levels

THE LOOP

  1. alpha · the number, from the constants
  2. levels · the energy ladder
  3. bohr · orbit sizes and speeds
  4. split <n> · the fine structure
  5. say what the simple model leaves out

NEVER

  • Claim α is exactly 1/137
  • Give levels for atoms of many electrons
  • Treat the orbits as paths seen

IT MAKES alpha — α and 1/α; levels — the levels, or one line; bohr — orbit sizes and speeds; split — the fine-structure spread.

THE STANDARD a pure number; not exactly 1/137; one electron only; the reduced mass; orbits are a model; the split is the name.

CITE THIS CARDTHE FINE-STRUCTURE CARD, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=fine-structure-card. Punch 4E54D6966B4F62FE63C519F9. Retrieved 2026-10-11.

What it is.

Works out the fine-structure constant α = e²/(4π ε₀ ħ c), about 1/137.036, a number without units: alpha computes it from the constants; levels gives the energy levels of hydrogen and hydrogen-like ions with the reduced mass, and the line between any two; bohr gives the simple atom's orbit sizes and electron speeds; split gives the fine-structure splitting of a level, the small α² correction the constant is named for.

It carries a machine that shows its working: alpha — α and 1/α; levels — the levels, or one line; bohr — orbit sizes and speeds; split — the fine-structure spread — 8 checks in its selftest, every command on the record. It will never claim α is exactly 1/137; never give levels for atoms of many electrons; never treat the orbits as paths seen. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.

Six laws, written into the card.

They are in the card itself, so the AI follows them.

A PURE NUMBERα has no units, so every system of measures gets the same value: 0.0072973525693.
NOT EXACTLY 1/1371/α = 137.035999…; the card never rounds it to the whole number.
ONE ELECTRON ONLYHydrogen, He⁺ and Li²⁺; atoms with more electrons need more than this formula.
THE REDUCED MASSThe nucleus moves too; the card includes it, which is why hydrogen's ground state is −13.598 eV and not −13.606.
ORBITS ARE A MODELThe radii are the most likely distances, not tracks an electron is seen to follow.
THE SPLIT IS THE NAMELevels with the same n split by about α² of their energy: the fine structure.

What rides in the card.

In the card’s own voice, with a machine that shows its working.

THE GUIDEreferences/THE-LAWS.md
THE MACHINEalpha.py · four commandsalpha — α and 1/α; levels — the levels, or one line; bohr — orbit sizes and speeds; split — the fine-structure spread. Every command prints its working and refuses a bad input; 8 checks in its selftest, every command on the record.

What it does once your AI has it.

  • alpha Α and 1/α
  • levels The levels, or one line
  • bohr Orbit sizes and speeds
  • split The fine-structure spread
  • On the record α = 1/137.036; hydrogen's ladder from −13.598 eV; the 3 → 2 line at 656.47 nm; the ground orbit 52.9 pm at 2,188 km/s; the n = 2 level split by 45 µeV.

What it will never do.

It will never claim α is exactly 1/137; never give levels for atoms of many electrons; never treat the orbits as paths seen. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.

Leaves out the Lamb shift, hyperfine structure and the nucleus's size; good to about one part in a million for hydrogen's levels, not for precision spectroscopy. It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →

Nº 1125 PROPOSED — LAUNCHING SOON

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.

A TERM, NOT A SUBSCRIPTION: NOTHING RENEWS ITSELF AND NOBODY IS CHARGED AGAIN. WHEN A TERM ENDS THE FILES STAY ON YOUR COMPUTER AND STAY READABLE — FREEZE, NOT LOSS.

QUESTIONS AT THE TABLE

Asked before the wire.

What does it need from me?

Alpha · the number, from the constants. It asks first for nothing for α; a level or two, and Z (1 to 3), for the atom.

Does it send anything anywhere?

No. The machine is a standard-library Python program that runs on your own computer and sends nothing anywhere; the words run wherever an AI reads Markdown. No server, no account, no key.

What is on the record?

The self-test (8/8) and every command run on real example inputs, pasted into WITNESS.md as they printed; the punch on the face is the SHA-256 of SKILL.md, so a downloaded copy can be checked against this room.

Can it be wrong?

Yes — it is an AI reading a text file. Leaves out the Lamb shift, hyperfine structure and the nucleus's size; good to about one part in a million for hydrogen's levels, not for precision spectroscopy.

What will it never do?

It will never claim α is exactly 1/137; never give levels for atoms of many electrons; never treat the orbits as paths seen. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
