The railways have a name for the peak-hour state of a Mumbai local: Super Dense Crush Load, sixteen people standing on every square metre of floor. The network carries about 7.5 million people a day, and between 2005 and 2024 more than 51,000 of them died on it. The fixes have been known for years. Most of them involve doors.

The Stockton and Darlington Railway opened on 27 September 1825 and is remembered as the birth of the steam railway. It was mostly a road. Anyone who paid the toll could put a wagon on it, most of the traffic was pulled by horses, and the steam engine nearly fell out of the Act of Parliament.

After water, sand is the most extracted material on earth, and we take fifty billion tonnes of it a year, faster than rivers make it. The awkward part is that the deserts are no use. Wind rounds the grains and rounded grains will not lock together, so the countries with the most sand still buy the sand they build with.

The first message across the Atlantic took sixteen hours to send. Three weeks later the cable was dead, and the electrician who killed it has carried the blame ever since. The cable he was handed had been manufactured in six months.

The mark on the side of a ship is named after a Member of Parliament who was ordered out of the Commons for calling other members villains. The Act that put it there let the shipowner choose how high up the hull to paint it, and that lasted fourteen years.

The shipping container was not invented in 1956, and the famous story of how a truck driver dreamed it up on a New Jersey pier is almost certainly something he made up in old age. What actually happened was slower, duller and far more consequential, and it went through a war and a committee before it reached anyone's shop.

The railway is about a century older than the locomotive. What got invented in the coalfields was the road, not the engine, and the width of that road was settled by colliery wagons in Northumberland. Britain made it law on 18 August 1846, having first been told in writing that the rival gauge was better. India spent thirty-three years and most of a network undoing the same kind of decision.

Cities replace their buildings every few decades and almost never replace what those buildings sit on. The street lines, the plot boundaries, the drains and the made ground survive everything, including fire, which is why the layer that fails is always the oldest one. Mumbai's engineers wrote the fix for its drains in 1993 and the city waited twelve years and 944 millimetres of rain before anyone acted on it. The reason is not corruption. It is that you cannot renovate a going concern from the foundations.

No country has ever announced its arrival on the world stage with a pamphlet. It builds something enormous instead. For a hundred and forty years, the surest way for a city or a country to tell the rest of the planet it had made it has been to put up the tallest building anyone has ever seen, and the story of how that habit started, in a burned-out patch of Chicago in 1885, explains almost everything about why skylines still work as a scoreboard today.

Every civilization has faced the same unglamorous problem: what to do with dirty water once a lot of people live close together. A handful of ancient cities solved it so completely, four and five thousand years ago, that parts of their work are still standing. Plenty of modern cities, with all the concrete and computing power in the world, still flood every time it rains hard.

Two of the worst industrial accidents of the last century were nuclear, and yet support for nuclear power is rising, more than thirty countries have pledged to triple it, and tech giants are switching old reactors back on. This is what the numbers actually say, which fears are real, and how the mood turned around.

Washington's fire crews reached Baltimore in thirty one minutes, the fastest run the railway had ever made. Their hoses did not fit the hydrants. The thread was incompatible on purpose, because incompatibility was how hydrant manufacturers kept competitors out.
