Their age
The idea stays. The evening changes.
You pick five or eighteen. Younger chairs get more lessons, shorter ones, a picture they can mark. The older chair gets a longer step and the same bar: can you do it.
Household year
A printable lesson: one idea, their age, a picture they look at first, a check they must pass. The year opens the courses already waiting. Then you can turn a talk, a chapter, or words you wrote into a lesson of your own.
You do not invent a curriculum on night one. Leonardo’s notebooks, a civic year, Western civ from the Greeks to 2000 — those are already written.
The promise
You are not buying a different product. You are pointing Lumen at talks and books you have the right to adapt.
Their age
You pick five or eighteen. Younger chairs get more lessons, shorter ones, a picture they can mark. The older chair gets a longer step and the same bar: can you do it.
The picture
Every lesson opens on a grey picture that is a question, not a poster. Then a short body, a check they must pass, mixed practice, and a pack you can print.
The return
One day, three, seven, twenty-one. Not a streak. The paper is what they bring to a kitchen, a backpack, or a week with no wifi.
Will this source work?
If you may copy and adapt the words, Lumen can make a lesson. Public domain, Creative Commons Attribution, CC0, or something you wrote. ShareAlike, no-derivatives, and “for non-commercial use only” will not do — a lesson is a derivative.
A lecture marked for adaptation. Blacksmithing, birds, a historian who released the words. Paste the transcript. Set the age.
A public-domain book, a CC BY textbook, a page you already have the right to use. One chapter becomes a lesson. A book becomes a year.
Your notes. A grandparent’s story typed up. A museum walk you wrote down. A recipe with a history. If you may adapt it, Lumen can teach it.
The canal, the hostel, the ceiling. Write what they saw. The lesson is the idea, not the photograph. The photograph can stay in the album.
Proof
These household courses are assembled from books and talks we may adapt. A year opens them. Pick one tonight. Bring your own later.

A household course from Herodotus to the year 2000. Primary texts in the public domain, Robinson and Van Loon as the survey spine, one CC BY international-relations survey for expansion and after, Civil Rights and Liberties (CC BY) for the unfinished American fights, and U.S. government speeches for 1941–2000.

A full household course on Leonardo from his own notebooks, the Treatise, Vasari’s Life, and one short public-domain biography. Later critics (Pater) are one sitting, not the spine.

A full household course on Michelangelo Buonarroti: the ruined marble, the Sistine vault as work, the Last Judgment, the sonnets from the scaffolding. Vasari and Condivi, then his own poems.

The Vatican is first a hill inside Rome: graves, a circus, a basilica, a palace, then a tiny sovereign city in 1929. Public-domain books carry the ground through 1870. The last sitting uses the Lateran Treaty as public law.

Galileo’s spyglass notes, not a poster of space. The moon is ground. Jupiter has attendants. You copy what he saw, then you look.

Newton’s first law in a kitchen: ice, a ball, a planet. The lecture is a household letter, not a textbook chapter.

Faraday’s six Christmas lectures. The flame is chemistry if you will sit with it.

Menabrea’s sketch of Babbage’s engine, then Lovelace’s notes. The machine is not a metaphor.

Mill on harm, Kant on a maxim you could will for everyone. Ethics as a real subject. No winner. The skill is naming the cost.

Ruskin’s first practice: the world is patches of grey. The picture is the problem, not the decoration.

FitzRoy’s barometer: the look of the sky lies, the column less often. Weather as a warning, not a vibe.

Vitruvius: a wall is a job, not a style. Carry it down to solid ground. Choose the stuff. Then it stands.

Agricola’s mine is a machine against rock, water, and air. Fire opens a vein. Fumes kill. The pump is the other half of the job.

Carnot: an engine is not a furnace. Heat must go from hot to cold. Steam is one way to carry it. Cold is the other half of the machine.

Kempe’s lecture: a ruler cheats. A circle does not. Watt almost draws a straight line. Peaucellier’s seven bars actually do.

Watt on a Sunday walk: stop cooling the cylinder. Send the steam to another vessel. The condenser is the invention.

Brunel’s Thames Tunnel: the shield is the machine. The river wants the hole. Journals, not a hero picture.

Chanute: add a second surface, then truss it. Lilienthal flew two thousand times and died of a wobbly joint. Equilibrium before a motor.

Morse at the packet-ship table: if electricity can be made visible anywhere on a wire, a sentence can travel. The mark is the invention.

Franklin: lightning is a household problem. Give the cloud a pointed rod and a path to wet ground. Do not hunt the spark.

Household course · 6 lessons
Faraday’s ring: one winding, another winding, a galvanometer. The neighbour feels the current. That is induction. Not a spark for show.

Maxwell’s elementary treatise: the work happens in the space around the body. Tubes, shells, a region. Faraday’s method, written so a Cavendish student can hold it.

Babbage’s Economy, not Note G. Tools add power, save time, and turn waste into a product. A tray that sorts needles is already an engine.

Telford’s Menai: a road hung from chains rooted in rock. Road-making was thought beneath an engineer. He did it anyway.

Smeaton’s Eddystone: Winstanley was a show, Rudyerd was wood, Smeaton wants stone. The sea is the load. The wedges are the joint.

Humboldt’s Cosmos: nature is a unity in diversity, not a stack of school subjects. The ocean, the plant, the star, and the hill share a page.

Marsh’s problem: wherever he plants his foot, the harmonies of nature are turned to discords. Not a sermon. A local inventory of what a person has moved.

White’s Selborne: one parish, letters, dates, and a worm that would make a lamentable chasm. A place is data if you will sit still.

James’s problem: consciousness does not appear chopped up in bits. It flows. Habit is the fly-wheel. Psychology is a subject, not a mood.

Dewey’s problem: thought starts when the road forks. Five steps, not a gift. Reflective thought is a habit you can practice at a table.

Jenner’s problem: a dairymaid’s cow-pox, a boy, two later tests. The body can be taught. You follow the cases. You do not reenact them.

Snow’s problem: cholera is in the water, and a map can say so. Broad Street. One handle. The picture is the argument.

Nightingale’s problem: a death in childbed is a calamity, not a percentage you shrug at. Tables first. The sickroom later, as a place you can still count.

Petty’s problem: you may count a city from its burials and its houses. Political arithmetic is a method, not a vibe about population.

Malthus’s problem: two rates that do not match. Population, when unchecked, doubles; food does not. Hold the ratios. Do not adopt his politics.

Archimedes as three pictures: a crown in water, a bar that moves the earth, a sphere inside a cylinder. Heath’s short book is the household spine.

Descartes puts a length on a line and a letter on the length. Geometry becomes something you can calculate without leaving the page.

Boole writes xx = x and means a class taken twice is the same class. Logic becomes a page you can calculate.

De Morgan’s Budget: a paradox is a claim apart from general opinion. Some are Copernicus. Some are circle-squarers. You catch them by drawing the error.

Poincaré: some hypotheses are conventions, not arbitrary, like a prince who consults. Geometry is a tool you can put down. Draw a triangle on a globe.

Dürer’s compass and rule: an A lives in a square of tenths. Measure first. The letter is the proof that you measured.

Goethe: colours are acts of light. An after-image is data. Yellow next to brightness, blue next to dark. The eye is the experiment.

Chevreul’s simultaneous contrast: two stripes in contact change each other. The picture is the experiment. Grey on a colour is not grey.

Reynolds to the Academy: nothing comes of nothing. Invention is a new combination of what you have stored. Copy first, then combine.

Raphael’s Vatican rooms are a commission, a relative’s letter, a shop. Vasari’s Life of Raffaello is a different problem from Leonardo or the Sistine: painting as employment.

Cellini dictates a life while he works. A goldsmith’s day is the plot. The Perseus is a cast, not a temperament.

Ruskin’s Stones of Venice, not the Elements of Drawing. A wall is a veil. Gothic is six characters of a builder. Seeing architecture is the problem.

Morris: have nothing in your houses that you do not know to be useful or believe to be beautiful. The lesser arts are everyone’s job.

Aristotle’s Poetics: a whole has a beginning, a middle, and an end. Rhetoric is not on Gutenberg/SE/OTL in English, so the arts sitting is a story that lands. Draw the plot as three boxes.

Hooke's glass on a needle, cork, and a flea. The small is built. You copy the plate before you believe the paragraph.

Gilbert's terrella, not a poster of poles. A small globe of loadstone stands in for the planet. The needle is the argument.

Newton's shutter and prism, not a rainbow poster. The image on the wall is oblong. Colour is in the ray, not in the glass. The falling-apple course is a different object.

Boyle in a garden, doubting fire-air-water-earth and salt-sulphur-mercury. An element is what you cannot take apart. The sitting is the doubt.

Lavoisier weighs the air that burning takes. Mercury calx gives the vital part back. The candle course watches a flame; this one keeps the books.

Priestley at a brewery, then a mint in a jar. Fixed air puts a candle out. A plant puts a candle back. The names are still half wrong. The facts are not.

Darwin's Beagle journal, not Origin. Fossils on a beach, tortoises that differ by island, corals that cannot live deep. The voyage is the problem.

Wallace's strait is fifteen miles. Bali has woodpeckers; Lombock has cockatoos. The map is a fight about old oceans, not a colouring sheet.

Pasteur's beer, not a hospital poster. Heat one bottle. Leave the other. The sediment grows strangers. Ferment is a plant, not a decay.

The ask
The parent pays. The child does not sign in. The tools and the courses you write stay on that household.
The catalog stays free. Cancel any month. If a lesson is wrong for the chair, pick another age and print again.
P.S. You remain the teacher. Lumen is not a school of record. We do not sell the MIT lectures.
