Q0433Before the telegraph, a message could travel only as fast as a body carrying it. Electric signals changed that: news, prices and instructions could cross long distances in minutes instead of days or weeks. Every modern instant message descends from that break. Once information escaped transport, the world started feeling smaller.
Q0434A written report asks you to imagine. A photograph puts a face, street or wound in front of you. From family portraits to war images, photography gave ordinary people and global events a new kind of evidence. The so-what is moral as much as technical: visibility can change what societies are willing to notice.
Q0435Before anaesthesia, surgery meant speed and agony. Ether and chloroform in the 1840s made operations survivable and calm — turning a last resort into real medicine.
Q0437Radio let a single voice reach millions of homes at once — carrying music and news, but also propaganda, and giving the 20th century a powerful new instrument of persuasion.
Q0438Early television looked small and experimental, but the medium later carried elections, moon landings, wars, football matches and everyday entertainment into living rooms. It mattered globally because millions could watch the same moment at once. Your phone inherited that habit of shared attention. The screen did not just show culture; it helped organise it.
Q0439The Manhattan Project built the first nuclear weapons during the Second World War, ending it and opening the atomic age — science that permanently changed global politics.
Q0441The 1986 Chernobyl disaster showed the cost of secrecy and flawed design: a reactor explosion spread radiation across Europe and shook trust in official reassurances.
Q0442A smartphone can replace a camera, map, music player, notebook, bank branch, newspaper and ticket machine. That compression matters globally because the same small object now mediates work, money, memory and relationships. It is useful, powerful and exhausting. The lesson is that convenience also concentrates dependency.
Q0443On 16 December 1947 Bell Labs built the first transistor — a tiny switch that replaced bulky vacuum tubes and made possible every computer and phone that followed.
Q0444In 1965 Gordon Moore noticed transistor counts on a chip doubling about every two years. 'Moore's Law' became a self-fulfilling target that drove the whole computing age.
Q0445On 29 October 1969 ARPANET sent its first message; the system crashed after two letters of 'LOGIN', so the first word online was simply 'LO' — a humble internet birth.
Q0446Ray Tomlinson sent the first network email in 1971 and picked '@' to separate the user from the host — reviving a near-forgotten symbol that is now everywhere.
Q0447IBM's RAMAC 350 in 1956 was the first commercial hard drive, storing 5 MB in a cabinet the size of a wardrobe — a phone today holds thousands of times more in a pocket.
Q0448In 1958–59 Jack Kilby and Robert Noyce independently invented the integrated circuit — packing many components onto one chip, the leap that made modern electronics possible.
Q0449Intel's 4004 in 1971 was the first commercial microprocessor — a whole computer's brain on one chip with 2,300 transistors, ancestor of the billions in today's phones.
Q0450Linux began in 1991 as a student's hobby, freely shared. Today it quietly runs most of the world's servers, phones and supercomputers — open collaboration at planetary scale.
Q0451In 1975 Kodak engineer Steven Sasson built the first digital camera — a toaster-sized box shooting 0.01-megapixel images to tape. Kodak feared it would threaten its film business.
Q0452A message can leave your phone, pass through cables under streets and seas, and arrive as light-guided data far away. Fibre optics matter because they give the internet enormous capacity without needing signals to crawl through copper alone. The global lesson is hidden infrastructure: the cloud still needs a physical world underneath it.
Q0453The first barcode scan, on 26 June 1974, rang up a pack of chewing gum in Ohio — a tiny beep that would go on to reorganise shops, supply chains and global trade.
Q0454Ethernet, developed at Xerox PARC in 1973, set the standard for wiring computers into local networks — the quiet plumbing that still links much of the connected world.
Q0455First demonstrated in 1960, the laser was famously 'a solution looking for a problem' — now it cuts steel, reads discs, performs surgery and carries the internet's light.
Q0456Bluetooth is named after Harald 'Bluetooth' Gormsson, a 10th-century Danish king who united tribes — as the tech unites devices. Its logo even blends his initials in runes.
Q0457The first website went live on 6 August 1991, and it simply explained what the World Wide Web was — a page about pages, the seed of everything online that followed.
Q0458IBM's Simon (1992) is widely seen as the first smartphone — a touchscreen phone with apps, email and a calendar, arriving fifteen years before the iPhone.
