Economy & Trade

Debt precedes coin by millennia: the first financial instrument is a tally of who owes what. Double entry makes an enterprise checkable by a stranger, and credit moves purchasing power across time, which the factory and the railway need and otherwise have no way to fund. The chain runs from the tally through the verified weight, the coin tested in public, the company that pools capital under disclosure, to a central bank that holds the price level.

Tracks

Each track is one line of development climbing the eight levels. A cell holds the step written at that level; cross-listed steps have their home in another sector and are shown here because this subject depends on them. Dashed cells are planned and not yet written; blank ones have nothing planned.

Money, credit and capital

Obligations recorded, weighed, coined, audited and lent.

Everything in Economy & Trade

Gathered from the steps above: the guides and builds that serve them, the reference sheets those carry, and every book the steps, guides and builds cite.

Field guides

Level 3
Mathematics

The results every other science and machine is built on, in the order each needs the last: the formula, what it states, what it lets you do, and who first found it.

 Level 0
Institutions: what to found, and how to run them

Every public institution an advanced civilisation runs, in the order a rebuilding one can found them: what each is for, when it becomes possible, and the rules that keep it honest, useful and no bigger than its job.

 Level 3
Calculating by hand

Four-figure logarithms and trigonometry, square roots by Newton's method, and the two instruments that did the world's arithmetic before electronics.
