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

THE PHOTON CARD · light in quanta: E = hf

WAKES WHEN someone asks about a wavelength, a colour, a photon's energy or a spectral line

THE LOOP

  1. photon <value> <unit> · all three
  2. hydrogen <series> · the lines
  3. count <W> <nm> · photons a second
  4. name the band it falls in
  5. say vacuum or air wavelength

NEVER

  • Mix vacuum and air wavelengths unsaid
  • Give a photon of zero wavelength
  • Treat colour names as exact edges

IT MAKES photon — wavelength, frequency, energy and band; hydrogen — the lines and the series limit; count — photons a second.

THE STANDARD h is exact; three faces of one thing; vacuum wavelengths; the reduced mass; colour names are bands; refused, not guessed.

CITE THIS CARDTHE PHOTON CARD, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=photon-card. Punch 0AF2A42E8555AA1CC7ABED9C. Retrieved 2026-10-11.

What it is.

Works out light as quanta, E = hf, with h = 6.62607015 × 10⁻³⁴ J s exact: photon turns a wavelength, frequency or energy into the other two and names the band (ultraviolet, green, infrared, radio); hydrogen gives the lines of hydrogen's series from the Rydberg formula with the reduced mass, in vacuum wavelengths; count gives the photons a second in a beam of a given power.

It carries a machine that shows its working: photon — wavelength, frequency, energy and band; hydrogen — the lines and the series limit; count — photons a second — 8 checks in its selftest, every command on the record. It will never mix vacuum and air wavelengths unsaid; never give a photon of zero wavelength; never treat colour names as exact edges. 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.

H IS EXACT6.62607015 × 10⁻³⁴ J s since the 2019 redefinition of the kilogram.
THREE FACES OF ONE THINGWavelength, frequency and energy are the same photon said three ways; the card gives all three.
VACUUM WAVELENGTHSHydrogen's lines are given in vacuum; in air they are about 0.03% shorter, and the card says so.
THE REDUCED MASSThe Rydberg constant for hydrogen, not the infinite-mass one, so Balmer alpha comes out 656.47 nm.
COLOUR NAMES ARE BANDSWhere green ends and cyan begins is a convention; the numbers are not.
REFUSED, NOT GUESSEDZero or negative values and unknown units are refused.

What rides in the card.

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

THE GUIDEreferences/THE-LAWS.md
THE MACHINEphoton.py · three commandsphoton — wavelength, frequency, energy and band; hydrogen — the lines and the series limit; count — photons a second. 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.

  • photon Wavelength, frequency, energy and band
  • hydrogen The lines and the series limit
  • count Photons a second
  • On the record A green laser's 532 nm photon carries 2.33 eV; 2.4 THz is far infrared; the Balmer lines from 656.47 nm; a 5 mW red pointer sends 1.6 × 10¹⁶ photons a second.

What it will never do.

It will never mix vacuum and air wavelengths unsaid; never give a photon of zero wavelength; never treat colour names as exact edges. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.

Hydrogen only, without fine structure (THE FINE-STRUCTURE CARD gives that); other atoms need measured tables. The bands are approximate. It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

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 1122 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?

Photon <value> <unit> · all three. It asks first for a wavelength, a frequency or an energy with its unit; or a series; or a power and a wavelength.

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. Hydrogen only, without fine structure (THE FINE-STRUCTURE CARD gives that); other atoms need measured tables. The bands are approximate.

What will it never do?

It will never mix vacuum and air wavelengths unsaid; never give a photon of zero wavelength; never treat colour names as exact edges. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
