Q0574During the First World War Marie Curie built mobile X-ray units, driving them to the front herself so surgeons could find bullets and shrapnel — her science put directly to saving lives.
Q0575In 1905, his 'miracle year', Einstein published papers that reshaped physics — all while working as a clerk in a Swiss patent office, doing science in his spare time.
Q0577Fibre is the part of plant food the body cannot fully digest, and that is exactly what makes it useful: it feeds gut bacteria, slows digestion and helps everything move through. Because it exists only in plants, a day with no fruit, veg, beans or wholegrains is usually a day with almost no fibre.
Q0602In his own lifetime Bach was admired more as a brilliant organist and keyboard player than as a composer — fame as a great composer came largely after his death.
Q0603Britannica notes Bach wrote over 1,000 works. The sheer volume matters: mastery on this scale came from relentless daily craft, not sudden bursts of genius.
Q0604Today Bach is treated as a colossus, but in his own time he was valued as a working church musician, quietly turning out masterpieces as part of the weekly job.
Q0605The Library of Congress notes about 180 Gutenberg Bibles were printed around 1455 — a small run by modern standards, yet each copy helped begin the print age.
Q0606Of roughly 180 Gutenberg Bibles, most were printed on paper and a few dozen on more luxurious vellum — even at the dawn of printing, there were premium editions.
Q0607The Van Gogh Museum notes we don't know exactly how many paintings Van Gogh sold in his life — the famous 'only one' story is likely too neat — but recognition came mostly after his death.
Q0608The Red Vineyard is the painting most clearly documented as sold in Van Gogh's lifetime — one confirmed sale from an artist now among the most beloved in the world.
Q0609Britannica describes Artemisia Gentileschi as one of the first women to win real fame as a painter — a Baroque master who painted bold, powerful women in an age that rarely allowed it.
Q0610The Smithsonian notes that Leonardo, who was left-handed, wrote much of his notes in mirror script — right to left, readable in a mirror — perhaps out of habit, privacy or both.
Q0611Leonardo's notebooks are less like tidy papers and more like a working laboratory on the page: muscle studies, flying machines, war devices, plant observations and painting problems sit side by side. For him, drawing was not just a way to record the world; it was a method for understanding it.
Q0614Van Gogh's lifetime sales are often exaggerated into a single sad statistic, but the deeper truth holds: value and recognition can arrive long after the work is made.
Q0616Bach's music is often described as the summit of the Baroque — its intricate counterpoint and balance so complete that later composers studied it as a model of the craft.
Q0617Bach had no modern studios or recording industry, yet composed prolifically for the resources at hand — proof that creativity works within limits, not despite them.
Q0619The decree honours the young pharaoh Ptolemy V. Its three parallel scripts — hieroglyphic, Demotic and Greek — turned the Rosetta Stone into the key that unlocked ancient Egyptian writing in 1822.
Q0620National Geographic notes the Great Pyramid is the only one of the Seven Wonders of the ancient world still standing — the sole survivor of a legendary list.
Q0621National Geographic notes the Great Pyramid was the tallest human-made structure on Earth for nearly 4,000 years — a record no building broke until the modern age.
Q0622After selling his roadside restaurant, Colonel Sanders drove the country in his sixties, pitching his fried-chicken recipe to owner after owner — persistence, not luck, built KFC.
Q0624The first Wright flight was brief, but crucially it was powered, controlled and sustained — the three things that separate true flight from a mere glide or hop.
Q0625Found in 1799 near Rashid (Rosetta) in Egypt and now in the British Museum, the Rosetta Stone records a priestly decree of 196 BC honouring Ptolemy V. Because the Greek version could be read, it became the key: Jean-François Champollion used it to crack hieroglyphs in 1822, reopening three thousand years of Egyptian writing.
Q0626The Gutenberg Bible was printed with movable type, yet some copies were finished on vellum and hand-decorated — a hybrid of mechanical printing and manuscript tradition.
Q0627Voyager launched in 1977, long before the first web server in 1990 — so a probe was leaving the Solar System before the web that now spans Earth even existed.
