Q1593
WonderTechnology

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.

Q1595
WonderTechnology

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.

Q1599
WonderHistory

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.

Q1604
WonderTechnology

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.

WonderHistory

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.

Q1618
WonderTechnology

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.

Q1619
WonderTechnology

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.

Q1621
WonderTechnology

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.

Q1670
DriveTechnology

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.

Q1671

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.

Q1679

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.

Q1680

Margaret Hamilton led the team that wrote the flight software for the Moon landings, and insisted on error-handling everyone told her was unnecessary. Three minutes before touchdown, that code saved the landing.

As the lunar module descended, alarms fired: the computer was being overloaded by a radar left switched on. Hamilton's software was built to recognise overload, shed low-priority tasks and keep the critical ones running — so instead of freezing, it kept flying the spacecraft. Mission Control gave the go. She had argued for that protection against colleagues who said astronauts would never make mistakes. She is also widely credited with coining the term 'software engineering', at a time when writing code was not regarded as engineering at all.

Q1682
DriveTechnology

While a well-funded rival with government money crashed his machine into a river, two brothers who repaired bicycles for a living flew theirs. Their advantage was not money but a wind tunnel and a bicycle-maker's grasp of balance.

Samuel Langley had substantial public funding and built for power. The Wrights, running a bicycle shop in Ohio, understood that the hard part was not lifting a machine but controlling it once up — the same problem as staying upright on a bicycle. They built a wind tunnel, tested over two hundred wing shapes because the published lift tables were wrong, and invented a way to warp the wings to steer. Langley's aircraft failed twice that year. The Wrights flew for twelve seconds on 17 December, and kept flying.

Nintendo was founded in Kyoto in 1889 to make hand-painted playing cards. Before it found video games it also tried instant rice, a taxi firm and a chain of love hotels, and nearly went under.

For most of its first century it sold cards, including a licensed range that did well but went nowhere. Under Hiroshi Yamauchi the company threw itself at anything that might work — a vacuum-powered toy hand, a photocopying business, packaged food — and lost heavily. Electronic toys and then arcade machines finally landed in the 1970s. The company is older than the aeroplane, the radio broadcast and the Nobel Prize, which makes it a useful reminder that most long-lived businesses are on their second or third idea.

Q1684
DriveTechnology

Ships could not work out how far east or west they were, and thousands died for it. A self-taught carpenter named John Harrison spent forty years building a clock accurate enough at sea to solve it — against astronomers who insisted the answer lay in the stars.

Latitude was easy; longitude required knowing the exact time at a reference port, and no pendulum clock could keep time on a rolling, damp, temperature-swinging ship. Harrison, a Lincolnshire carpenter with no formal training, built a series of increasingly refined machines, ending with a watch about the size of a large pocket watch that lost only a few seconds on a voyage to Jamaica. The Board of Longitude, dominated by astronomers backing a rival method, withheld the prize for decades. He was eventually paid after appealing to the king.

Q1714
WonderLanguage

In 1999 Shigetaka Kurita designed 176 emoji on a 12-by-12 grid, giving early mobile messages a way to carry weather, tone and feeling.

Kurita's original emoji were tiny, practical drawings for Japanese phones and pagers: hearts, clouds, trains, faces, symbols. MoMA later acquired the set because design does not have to be large to change behaviour. Those little squares made text feel less bare. They reminded digital messages that a body, a mood and a raised eyebrow were missing.

Q1718
WonderLanguage

Morse code gives the shortest signals to frequent letters: E is one dot, T one dash. It turned language into a design problem measured in time.

The brilliance is compression. A rare letter can afford a longer pattern; a common one cannot. Alfred Vail studied type cases and newspaper frequency while shaping the code, so ordinary English could move faster over wire. Before data compression had a name, telegraphers were already asking the modern question: what do people say most often, and how do we spend fewer signals saying it?

Q1725
WonderArt

In 2018 Banksy's Girl with Balloon passed through a shredder hidden in its frame seconds after auction, becoming the work Love is in the Bin.

The stunt worked because it attacked the exact room that had just priced the object. But the market absorbed the attack, certified it, named it and sold it again. That is the sharper joke. Destruction did not end the artwork; it became its provenance. Contemporary art often asks whether the frame is part of the work. Banksy made the frame bite back.

Q1729
WonderArchitecture

Badgirs, or windcatchers, guide air down from roof towers to ventilate and cool buildings in hot, dry climates.

A windcatcher is architecture that behaves like a lung. Vents catch moving air above the roof and pull it down into rooms or cisterns; in still weather, warm air rising can draw cooler air through shaded spaces. The lesson feels newly old: comfort can be designed with climate instead of only against it. Before the switch and compressor, there was section, shade, pressure and patience.

Q1730
WonderEngineering

A qanat taps groundwater and carries it gently downhill through an underground tunnel, using gravity instead of machines.

From above, a qanat line looks like a trail of small craters crossing dry land. Below, it is a carefully sloped tunnel, maintained through vertical shafts, bringing aquifer water to fields and settlements. The technology is ancient but not crude. It requires surveying, communal rules and long-term restraint. A pump can take quickly. A qanat has to keep the future in the gradient.

Q1732
WonderClimate

The Svalbard Global Seed Vault stores duplicate seed samples at -18°C, an insurance policy for crop diversity and future food security.

The vault does not replace living farms or working seed banks. It backs them up. Boxes arrive under black-box conditions, owned by the depositors, and are stored deep inside rock above Longyearbyen. The quiet drama is that crop diversity is memory too: drought tolerance, disease resistance, local taste, old adaptation. A seed in a mountain is a promise that not every future has to start from scratch.

Q1742
WonderMigration

Polynesian navigators crossed open ocean without magnetic compasses, reading stars, sun, swells, birds and carefully remembered motion.

A star compass is not an object in the hand. It is a disciplined map in the mind. Traditional wayfinders tracked rising and setting stars, the feel of ocean swells, wind shifts, birds and the memory of speed and direction. This is technology in a deeper sense: not always metal, not always machine, but a trained relationship between attention and world.
