Q1487

WonderArt

Fine white porcelain was made in China for around a thousand years before anyone in Europe could reproduce it — which is why fine tableware is still simply called 'china'.

The secret was a particular white clay, kaolin, fired at very high temperatures, and it was guarded so well that European makers spent generations and fortunes failing to copy it, finally cracking the recipe around 1708. A material can carry a whole trade empire inside it: pots so prized that nations chased their formula like a state secret.

The oldest surviving photograph, made by Joseph Nicéphore Niépce around 1826, needed an exposure of several hours — long enough that the sun moved across the sky and lit the courtyard's buildings from more than one side.

The blurry rooftop view, captured on a polished pewter plate coated with light-sensitive bitumen, is faint and strange, but it is the first time a real scene fixed itself onto a surface without a human hand drawing it. Every photograph since — every selfie, every satellite image — descends from that patient, hours-long stare out of a French window.

The Vera C. Rubin Observatory released its first images in June 2025 — capturing roughly 10 million galaxies and spotting more than 2,000 previously unknown asteroids in about ten hours of looking.

Perched on Cerro Pachón in Chile with an 8.4-metre mirror and the largest digital camera ever built, Rubin is designed to photograph the entire southern sky every few nights for ten years. That time-lapse of the universe — the Legacy Survey of Space and Time — should catalogue billions of galaxies and reveal anything that moves or flickers.

WonderTechnology

In 2025 scientists used artificial intelligence to design the genomes of working viruses that attack bacteria — the first time AI had written a complete viral genome that then functioned in the lab.

The targets were bacteriophages — harmless-to-humans viruses that infect bacteria. An AI model trained on natural genomes proposed new ones; in the lab, 16 of these designs assembled into phages that could kill their bacterial hosts. It is an early, carefully bounded step towards designing biology, and it arrives with real questions about how such power should be governed.

The US Army ran a secret unit of artists, designers and sound engineers who fought the Second World War with inflatable tanks, recorded troop noise and fake radio traffic. They staged more than twenty deceptions and are thought to have saved thousands of lives.

Roughly 1,100 men, many recruited from art schools and advertising, could impersonate a division of 30,000. They inflated rubber tanks and lorries, played recordings of armoured columns through enormous speakers audible for miles, and sent radio chatter to be intercepted. Fashion designer Bill Blass and painter Ellsworth Kelly served among them. The work stayed classified for decades; the unit finally received the Congressional Gold Medal in 2024, by which time only a handful of its members were alive to accept it.

In 1983 an Air Canada jet ran out of fuel at 12,500 metres because someone had calculated the load in pounds instead of kilograms. The pilots glided it down and landed on a disused runway that had become a racetrack.

Canada had recently gone metric, and the fuelling sum was done with the old conversion factor, leaving the aircraft with about half the fuel it needed. Both engines stopped mid-flight. Captain Bob Pearson happened to be an experienced glider pilot; first officer Maurice Quintal remembered a former airbase at Gimli, Manitoba. It was now a drag-racing strip, with a race meeting under way. They landed the airliner on it, nose gear collapsed, and stopped short of the crowd. Nobody was seriously hurt.

After a walk in the Alps in 1941, George de Mestral grew curious about the burrs stuck to his dog. Under a microscope he found tiny hooks catching in loops of fur — and spent the next decade turning that into Velcro.

Most people pull the burrs off and think no more about it. De Mestral, a Swiss engineer, looked closer and saw a fastening system nature had already solved. It took years to work out how to mass-produce hooks and loops in nylon; textile manufacturers thought the idea absurd. He named it from velours and crochet — velvet and hook. It is one of the founding examples of biomimicry, the practice of copying nature's engineering, and it went to the Moon on Apollo spacesuits.

In 1913 a Sheffield metallurgist was trying to make gun barrels last longer. His experiment failed and the samples went on the scrap pile — where he noticed weeks later that one of them had not rusted.

Harry Brearley left school at twelve and taught himself chemistry in the evenings. Adding chromium to steel had not solved the erosion problem he was hired to fix, so the offcuts were discarded. Passing the heap later, he saw one sample still bright while the rest had gone brown — chromium forms an invisible oxide film that seals the surface. He saw at once that it belonged in cutlery rather than artillery. Sheffield called it 'rustless steel' at first, and the world eventually settled on stainless.

In 1905 Frank Epperson left a cup of fruit soda on his porch overnight with the stirring stick still in it. San Francisco froze, and he came out to find the first ice lolly. He patented it eighteen years later.

He was eleven. He showed it to friends, kept making them, and only in 1924 filed a patent for 'frozen confection on a handle', originally selling them as Epsicles. His children reportedly preferred 'Pop's 'sicles' — hence popsicle. The company was sold during the Great Depression and became a global business. It is the tidiest example of the general rule that many inventions are simply an accident somebody bothered to notice twice.

In 1903 a French chemist knocked a glass flask off a shelf. It cracked but held its shape — a film of dried plastic inside had kept the pieces together. Car windscreens have worked that way ever since.

The flask had held cellulose nitrate, which had evaporated and left a clear lining. Bénédictus thought little of it until he read newspaper accounts of drivers badly cut by flying windscreen glass in the new motor cars. He went back to the flask, patented laminated glass, and the motor industry — initially reluctant about the cost — adopted it once the accident figures became impossible to ignore. The same sandwich of glass and plastic is in the windscreen of every car on the road today.

In 1938 Douglas Corrigan was refused permission to fly the Atlantic. He took off from New York saying he was going to California, and landed 28 hours later in Dublin, claiming he had misread his compass. Nobody believed him, and nobody minded.

Corrigan had helped build Lindbergh's Spirit of St Louis and had been applying for years to make his own crossing; his patched-up aircraft was repeatedly judged unfit. So he filed for a transcontinental flight, pointed the nose east into the cloud, and turned up in Ireland. Officials suspended his licence for precisely the length of his voyage home. America adored him — he got a ticker-tape parade bigger than Lindbergh's — and he maintained the compass story, straight-faced, for the rest of his life.

In 1943 a naval engineer was designing springs to steady instruments on rough seas. One fell off a shelf and walked itself end over end across the floor. His wife found the name in a dictionary: Slinky.

James watched the spring tumble gracefully instead of clattering, and realised he had a toy rather than an instrument mount. Betty James found 'slinky' — meaning sleek and graceful — in a dictionary. The first 400 sold out in ninety minutes at a Philadelphia department store in 1945. Betty went on to run the company for decades after Richard left. Hundreds of millions have been sold, and NASA has taken Slinkys into orbit to demonstrate how springs behave without gravity.

Play-Doh began life as a putty for rubbing coal smoke off wallpaper. When homes switched to gas heating the business was dying — until a teacher mentioned children liked modelling with it.

Kutol of Cincinnati made a doughy compound that lifted soot from wallpaper without water. As coal fires gave way to gas and vinyl wallpaper arrived, demand collapsed. Kay Zufall, a nursery school teacher, read that the putty made good modelling clay and told her brother-in-law at the company. They removed the detergent, added colour and almond scent, and relaunched it as a toy in 1956. More than three billion cans have sold since — a cleaning product saved by children finding the better use for it.

A chemist searching for clear gun sights in 1942 kept producing a compound that stuck to everything and ruined his equipment. He set it aside twice. Only years later did he realise the sticking was the product.

Cyanoacrylate bonded instantly to anything faintly damp — including skin and lab glass — which made it useless for the optics work Coover was doing. He rediscovered it in 1951 while developing heat-resistant aircraft canopies, and this time recognised what he had: an adhesive needing no heat or pressure. It reached shops in 1958. Field surgeons in Vietnam used a spray version to close wounds fast enough to get men to hospital, and medical-grade cyanoacrylate still seals surgical incisions today.

Before Apollo 11 landed, the White House quietly prepared a statement to be read if Armstrong and Aldrin were stranded on the Moon. It was never delivered, and stayed unknown for thirty years.

There was no way to rescue a crew stuck on the lunar surface; if the ascent engine failed they would simply have run out of air. Speechwriter William Safire drafted the contingency address, which begins by saying the men who went to the Moon to explore in peace will stay to rest in peace, and instructs that contact be cut before Mission Control closes with a version of a burial at sea. The memo surfaced in 1999. It is the finest thing ever written that nobody had to hear.

For 84 years a mechanical figure in Turkish dress toured Europe beating chess champions, Benjamin Franklin and Napoleon. Inside the cabinet, hidden behind sliding machinery, sat a human player.

Wolfgang von Kempelen built it for the Habsburg court, and the illusion was in the cabinet: doors were opened one at a time to show gears while the operator slid quietly into the cleared space. A series of strong players took the seat over the decades. Edgar Allan Poe wrote an essay arguing correctly that a human must be inside. It burned in a Philadelphia fire in 1854. Amazon later borrowed the name for a service where humans quietly do the tasks software cannot — the joke intended.

Hundreds of Roman scrolls carbonised by Vesuvius are too fragile to unroll — touching them turns them to dust. Researchers now scan them and let AI read the writing inside, without opening them at all.

The scrolls come from a villa at Herculaneum, the only library to survive from the ancient world. Brent Seales's team at Kentucky developed a way to X-ray a scroll, digitally unwrap the layers and train machine learning to spot the faint texture of carbon ink on carbon paper. A global prize competition followed: the first word recovered, in 2024, was πορφύρας — 'purple'. By 2026 an entire scroll had been read end to end. Hundreds more remain, and no one knows what is in them.

In 1942 the actress Hedy Lamarr and composer George Antheil patented a way to stop radio-controlled torpedoes being jammed, by hopping the signal across frequencies. The same principle underlies wifi, GPS and Bluetooth.

Lamarr was billed as the most beautiful woman in the world and was bored by the parts she was given; she kept an inventing table at home. The frequency-hopping idea came with a mechanism synchronised by piano rolls — Antheil's contribution — and the US Navy filed the patent away unused. It expired before it earned either of them anything. Related techniques became fundamental to secure and shared wireless communication, and she was finally inducted into the National Inventors Hall of Fame in 2014, fourteen years after her death.

When an oxygen tank exploded 320,000 km from Earth, three astronauts sheltered in a lunar module built for two. Engineers on the ground had to make its square air filters fit round sockets, using only what was aboard.

Carbon dioxide was climbing towards lethal levels. A team at Mission Control was handed a duplicate of every item on the spacecraft and told to build an adapter from it — the answer used plastic bags, cardboard from a flight manual, tape and a sock, read up to the crew step by step over the radio. It worked. The lunar module, never designed as a lifeboat, kept three men alive for four days, and all three came home. NASA called it a successful failure.

In 1938 a chemist opened a cylinder of gas that weighed full but released nothing. He sawed it open and found the gas had turned itself into a white, slippery powder that almost nothing would stick to: Teflon.

Plunkett was working on refrigerants at DuPont. The tetrafluoroethylene had polymerised on the cylinder walls into PTFE, a substance so unreactive that acids do not touch it and so slippery it is among the lowest-friction solids known. Its first serious use was in the Manhattan Project, sealing equipment against ferociously corrosive uranium compounds. Frying pans came much later, after a French engineer's wife suggested putting it on cookware. Plunkett always described it plainly as an accident.

John Goodenough co-created the rechargeable battery that runs phones, laptops and electric cars. He received the Nobel Prize in 2019 at the age of 97 — the oldest person ever to be given one — and kept going into the lab afterwards.

He did not begin studying physics until after serving in the Second World War, and was told he was starting too late. He was 57 when he made the breakthrough that gave lithium batteries enough voltage to be useful. He never earned significant royalties from it. In his nineties he was still publishing, still chasing a safer solid-state battery, and reportedly said that he had no intention of retiring while he could still be useful. He died at 100.

When Volvo's engineer designed the three-point seatbelt in 1959, the company made the patent freely available to every other manufacturer rather than keep the advantage. It is credited with saving more than a million lives.

Earlier belts held only the lap, which in a serious crash could do severe internal damage. Bohlin, who had previously designed ejector seats for aircraft, worked out a Y-shaped belt that restrained chest and hips at once and could be fastened with one hand — the detail that made people actually use it. Volvo published the patent openly. Rarely does a company hand a rival its main safety advantage; it is among the clearest cases of a commercial decision made on the arithmetic of lives rather than sales.

Tim Berners-Lee built the World Wide Web at a physics laboratory, then persuaded his employer to release it into the public domain in 1993 with no fee and no patent. He could have owned the doorway to the internet.

He wrote the first browser, the first server and the language pages are still written in, to solve a mundane problem: physicists at CERN could not easily share documents. His argument for giving it away was practical as much as moral — a web that anyone had to pay or ask permission to build on would simply not have grown. Competing systems of the era charged licence fees, and are forgotten. He has since spent much of his career arguing that the thing he built has become too centralised.

James Dyson spent five years making prototype after prototype of a vacuum cleaner with no bag. The 5,127th worked. Every British manufacturer turned it down, so he manufactured it himself.

The idea came from a sawmill, where large cyclones spun dust out of the air. Dyson reasoned the same physics could replace the bag that clogs and loses suction. Manufacturers were not interested — the industry made steady money selling replacement bags, and a machine that needed none threatened that. He launched in Japan first, then in Britain, where it became the best-selling vacuum within a few years. He has since said the failures were the education, and that he learned nothing from the one that worked.
