Q1298Engineers working on the Harvard Mark II traced a fault to a moth caught in a relay and taped it into the logbook, noting the 'first actual case of bug being found'. The word for a glitch was already old, but the story stuck.
Q1299Once used mainly by merchants to mean 'at the rate of', the @ sign was nearly forgotten. In 1971 Ray Tomlinson chose it to separate a user from a host in the first network email — and gave it a second life.
Q1300The wireless standard's dull official name is IEEE 802.11. A branding firm coined 'Wi-Fi' simply because it sounded friendly and hinted at 'hi-fi' — it was never short for 'wireless fidelity', despite the popular myth.
Q1327Long before video games, Fusajiro Yamauchi opened a small shop in Kyoto in 1889 selling handmade 'hanafuda' flower cards. Nintendo made playing cards for decades, dabbling in taxis, instant rice and love hotels before finding its future in electronic games in the 1970s. It still prints playing cards in Japan today — a company that has quietly outlived most of the industries it was born alongside.
Q1328Two engineers sealed two shower curtains together, trapping air in bubbles, hoping to sell it as a trendy 3D wallpaper. It flopped. They next pitched it as greenhouse insulation — also a flop. Only when IBM began shipping delicate computers did its true calling appear: protective packaging. A product can fail at everything it was designed for and still become indispensable at something no one imagined.
Q1345Printed in Korea in 1377, Jikji is the oldest surviving book printed with movable metal type. Gutenberg transformed Europe, but metal-type printing has a wider world history, and Korea belongs at the center of that story.
Q1370Her compiler work helped make software less like wiring a machine and more like writing instructions. That shift made computing more teachable, scalable and human.
Q1371The Event Horizon Telescope linked radio observatories across the planet to see the shadow of the black hole in galaxy M87. It was less a single camera than a global act of precision and patience.
Q1373Used for astronomy, timekeeping, navigation and prayer, astrolabes travelled from ancient Greek science through the Islamic world into Europe. They show technology as both calculation and beauty.
Q1381Researchers have shown that some mounds act like living lungs, using day-night temperature swings to move air and flush out carbon dioxide. Good design does not always add power; sometimes it studies what already works.
Q1387Toyota's jidoka principle gives people and machines permission to stop when an abnormality appears. It sounds inefficient until you see the deeper logic: a hidden defect is more expensive than a paused line.
Q1388Spencer Silver at 3M developed a low-tack adhesive; Art Fry later saw its use as a bookmark that would not damage pages. Innovation is often not a straight line from problem to solution. Sometimes the solution waits years for the right problem.
Q1390Before containerization, cargo was often loaded piece by piece: crates, sacks and barrels handled slowly by armies of workers. Standard boxes cut friction from the journey, lowering cost and reshaping ports, factories and supply chains. Much of modern life arrives inside an object designed to be almost invisible.
Q1398A MIDI message can say which note was played, how hard and for how long, while another device produces the sound. That made electronic instruments easier to connect, edit and control. A cheap shared standard opened music production far beyond large studios.
Q1400Foley is the craft of performing everyday sounds in sync with the image: footsteps on gravel, a coat sleeve moving, a cup placed on a table. If it works, the viewer forgets it was made. The invisible craft makes the fiction feel solid.
Q1402Launched in Kenya in 2007, M-Pesa let people move money through mobile phones and local agents, even where bank branches were distant or impractical. It showed that financial infrastructure can be a handset, a trusted shop and a network people already use.
Q1403The curb cut is a small slope in the pavement, but its history is political as well as practical. It came from disabled people demanding the right to move through public space. Its afterlife is a design lesson: when a city removes one barrier honestly, the benefit often travels farther than the original brief.
Q1404Sam Farber watched his wife Betsey struggle with a traditional metal peeler because of arthritis. The result was not a medical gadget, but better everyday tools: peelers, knives and utensils with bigger, non-slip handles. Designing for limited grip made the kitchen easier for many hands.
Q1408DENSO WAVE introduced the QR code in 1994. It could hold more information than a barcode and be read fast from different angles. A humble label for manufacturing later became a bridge between posters, tickets, payments, menus and the web.
Q1410It is not a style of house, but a performance standard. Thick insulation, airtight construction, strong windows and heat-recovery ventilation keep indoor temperature comfortable with far less heating or cooling. The climate work begins before the appliance is switched on.
Q1411Used in hot, dry regions such as Yazd in Iran, windcatchers work with shade, pressure and air movement rather than electric machinery. They remind us that old architecture can carry climate knowledge in its very shape.
Q1418A dabba is a lunchbox. The special part is coordination: one meal may be collected at home, sorted by hand, moved by train, delivered to the right desk, then sent back empty the same day. Long before delivery apps, reliability came from timing, trust, repeated routes and readable marks on boxes.
Q1419Developed in India, it uses affordable materials and a flexible form suited to everyday movements that expensive prosthetics can overlook. The lesson is not only price; it is respect. Good design begins by asking how people actually live, sit, work, pray and walk.
Q1422Print already had footnotes and references, but the web made the jump immediate. One underlined phrase could move a reader from a document to an archive, from a claim to a source, from one mind to another. The hyperlink is small enough to miss, yet it changed reading from a line into a landscape.
