The history of cartography is usually told through its errors, and four mapmakers illustrate why.

A. Gerardus Mercator's 1569 projection solved the navigator's hardest problem: how to steer a constant compass bearing across an ocean along a straight line. To achieve it he stretched the far latitudes, and Greenland grew to the size of Africa. Sailers forgave the distortion; schoolchildren, staring at wall maps four centuries later, inherited a planet that never existed.

B. Abraham Ortelius, an Antwerp engraver, did something quieter. In 1570 he assembled existing maps into the first modern atlas, the Theatrum Orbis Terrarum, and in doing so standardised the look of geography for a century. His own contribution was less the drawing than the editing: he compared sources, discarded the least reliable, and credited them in a list at the back.

C. The Venetian monk Fra Mauro worked a generation earlier, around 1450, and his circular world map reads today like a database. Some 3,000 inscriptions record what sailors and merchants told him, with contradictory accounts faithfully preserved side by side. Where authorities disagreed, Fra Mauro refused to choose, an honesty that makes his map useless for navigation and invaluable to historians.

D. Captain James Cook's charts of the Pacific, drawn between 1768 and 1779, were accurate enough that some remained in commercial use into the 1990s. His precision came from method rather than genius: latitude from sextant, longitude from lunar tables, coastlines surveyed boat by boat. He mapped the east coast of Australia and, in passing, ended the theoretical continent geographers had placed there for two centuries.

The stories of three researchers trace how vaccination moved from folklore to laboratory.

A. Edward Jenner noticed what dairy workers knew before him: those who caught cowpox from infected udders seemed spared the deadly smallpox that swept the country each year. In 1796 he tested the folk observation directly, inoculating a boy with cowpox matter and later with smallpox, which the boy resisted. Jenner called the procedure vaccination, from vacca, the cow, and spent his remaining decades campaigning for it, distributing lymph to any physician who asked.

B. Louis Pasteur approached immunity from the chemistry of germs rather than the folklore of farms. His breakthrough came from a laboratory accident: chicken cholera cultures left over summer lost their force, and the chickens injected with the weakened germs survived, later resisting fresh cultures. Pasteur saw the principle, weakening organisms deliberately, and honoured his predecessor by extending the word vaccine to cover the whole method.

C. Maurice Hilleman worked in a different world, the pharmaceutical industry, where his laboratory produced more than forty vaccines across a career. When mumps struck his young daughter in 1963, he swabbed her throat that night, cultured the virus, weakened it, and the resulting vaccine was given to a million children within four years. He never won the public fame of the earlier pioneers, partly because he worked inside a company and partly because he distrusted press attention.

D. Katalin Kariko spent decades pursuing an idea her funders abandoned, that laboratory-made messenger RNA could instruct cells to build their own defences. Demoted and grantless through the 1990s, she kept refining the technique with a single collaborator, and the modified RNA chemistry they developed became the backbone of the vaccines deployed against the 2020 pandemic, arriving forty years after her first experiments.

A. Vinyl's survival is the strangest story in recorded sound. Declared dead by 1990, pressed by a handful of specialist plants by 2005, it re-emerged as the format that buyers wanted to own rather than stream, and by the 2020s new pressing plants were opening to meet demand that exceeded capacity. Its appeal is partly ritual, the large sleeve, the deliberate act of playing, and partly honest economics: a vinyl sale pays artists several times what the same listening streams.

B. The compact cassette taught the world to make its own recordings. Cheap, recordable and rugged, it turned teenagers into curators of mixtapes and, in much of the world, into distributors, since cassette duplication built the first pirate music industries of West Africa and South-East Asia. Its Western decline with the CD was so complete that the format's current niche revival depends on a single remaining factory supplying tape to a nostalgia market.

C. The compact disc arrived as the first perfect format: digital, silent between tracks, allegedly immortal. It sold music twice, as owners replaced collections, and its crash after 2000 taught the industry a lesson it learned too well, that convenience beats fidelity. The CD's residual market, cars and Japan aside, is now classical and jazz, genres whose listeners still buy physical objects and full albums.

D. Streaming is the format that is not a format, no object, no ownership, a library negotiated monthly. It solved piracy by making legal listening easier than stealing, and it reversed the industry's revenue collapse, while quietly resetting the economics: payment by play favours tracks over albums and playlists over artists, and the back catalogue, bought cheaply by labels, now outearns most new releases.
