Civilization101Blueprint

Health & Medicine

Most of the gain comes early and costs little: clean hands, soap, clean births, oral rehydration and enough of the right food. Bleeding is stopped with hard, uninterrupted pressure; a burn gets 20 minutes of cool running water; a contaminated wound is left open. Germ theory and the microscope (level 3) turn those habits into a discipline. Anaesthesia, antibiotics and vaccines follow only once sterility and a cold chain exist. The science under all of it, from the cell and the anatomy of the body to immunity and epidemics, is in biology.

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.

First aid and surgery

Stop the bleeding, clean the wound, splint the break, and later operate under anaesthesia.

Everything in Health & Medicine

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 0
Wound care and first aid

Without antibiotics, a cut is a slow emergency and a deep bite is a fast one. What saves people is mostly pressure, water, and knowing which wounds must be left open.

 Level 1
The body's numbers

Normal pulse, breathing, temperature and blood pressure; the signs that mean danger in a child; and how much water a body needs.

 Level 1
Poisons

The poisonings a rebuilding community is most likely to meet: where each comes from, how it shows, and the first thing to do.

 Level 3
Biology

Life from the cell up: the human body, microbes and immunity, inheritance and epidemics. Each result with what it lets you do and who first found it.

 Level 3
Micro-organisms

The two dozen that decide who lives where there is no doctor: what each does, how it spreads, what kills it and which step stops it.

 Level 3
Essential medicines

The basic set from the WHO list: what each treats, what it is made from, and the earliest tier that can make it. No doses, on purpose.

 Level 0
Sanitation and disease

The distance between a latrine and a well, a bar of soap, and a covered pit prevent more deaths than every hospital on the ladder combined.

 Level 3
Chemistry

What matter is made of and how it changes: amounts, gases, acids, the energy and speed of reactions, electrochemistry, and the reactions every industry on the ladder runs on.

 Level 3
The sciences

Fourteen branches, each with the handful of results a civilization cannot rebuild without, and where to learn the rest.

Builds

Inside a sawdust latrine — seat, chute, and the bin of cover material that makes the system work.
Level 1
Twin-vault composting latrine

Break the faecal–oral route and return the nutrients — the highest lives-saved-per-effort structure a settlement can build.
A replica of a Leeuwenhoek microscope, about 5 cm tall: the tiny glass lens sits in the hole at the top of the brass plate, the specimen goes on the point just behind it, and the screws move the point to focus. The eye goes right up against the plate.
Level 3
Bead microscope

A glass bead the size of a pinhead magnifies 150–350 times: enough to see yeast, blood cells and the larger bacteria that cause disease.
