Recent Changes

The world's first jet airliner, the [[de Havilland Comet]], had square windows that caused disaster. Pressurization cycles concentrated stress at the corners, causing [[metal fatigue]] cracks; in 1954 two Comets broke apart mid-air, killing dozens. Every airliner window since has been oval.

At the 2026 [[Asian Games|Aichi-Nagoya Asian Games]], the video game [[Puyo Puyo]] was a full medal [[Esports|esport]]. In the final, 11-year-old Japanese player Yuki Kurihara beat South Korea's Kang Dong Shin 10-2 for gold, becoming the youngest athlete in Japan's Asian Games history.

[[Chuseok|Chuseok's]] [[Full Moon|full moon]] isn't always perfectly full. The lunar calendar sets day 1 at the new moon, but the Moon's elliptical orbit makes it move at uneven speed, so the true full moon often misses day 15 — in 2026 it lands two days after Chuseok, on September 27.

On September 18, 2026, a 3.5 m [[shark]] entered a canal at North Port Waterfront Park in [[Busan]] and circled for days, unable to get out. Warned that forcing it out could make it aggressive, the coast guard backed off. Nicknamed "Bukangi," the shark drew about 30,000 sightseers in one weekend.

Starting with the 2026 [[FIFA World Cup]], covering your mouth during a confrontation can draw a red card. The rule followed [[Vinícius Júnior]] accusing a Benfica opponent of racial abuse—but the opponent had covered his mouth, so UEFA couldn't gather evidence.

On U.S. [[Yu-Gi-Oh!]] cards, [[Dark Magician Girl]]'s chest pentagram was erased and replaced with a red gem. Localizer 4Kids scrubbed pentagrams and other religious symbols from card art to dodge the 1990s American 'Satanic Panic'—even though the franchise has no real link to Satanism.

400,000-year-old [[Homo erectus]] teeth from China carry an enamel protein mutation once thought exclusive to [[Denisovan]]s. A 2026 study using new fossil-protein analysis found the same mutation in some modern Southeast Asian and Oceanian people, linking all three groups genetically.

[[Oreo]] creme sticks to the same wafer about 80% of the time, however you twist it. MIT engineers twisted 1,000+ cookies in 2022 and traced the cause to manufacturing, not habit: on the line, creme lands on the first wafer before the second is added, giving it extra bonding time.

Many 2026 [[FIFA World Cup]] stadiums are [[NFL]] venues that normally use turf. Since FIFA requires real grass, sod grown for months at farms is cut, trucked in, and relaid weeks before matches. [[MetLife Stadium]] got an entirely new grass field shipped from a North Carolina farm.

In May 2024 an impact carved a fresh [[Crater|crater]] on the [[Moon]]'s near side, bigger than the Roman Colosseum — yet no telescope on Earth caught it happening. It sat unnoticed in [[NASA]]'s Lunar Reconnaissance Orbiter image archive until spotted by chance in August 2025.

[[Instant noodles]] are yellow because of added [[vitamin]] B2. In the 1980s, ramen companies began adding vitamin B2 to address nutritional concerns. The alternate name for vitamin B2, "riboflavin," contains "flavin"—derived from the Latin word "flavus," meaning yellow.

[[Dizzy Dean]], a [[National Baseball Hall of Fame]] inductee who retired at 31, became a commentator known for relentlessly criticizing players. His team eventually put him on the mound to prove his words. At 37, six years after retirement, Dean pitched four scoreless innings.

In [[Pokémon]] Red and Blue, the [[Old man|old man]] blocking the road out of [[Viridian City]] was passed out drunk in the Japanese original. Western versions changed it to 'grumpy without his morning coffee' — but his sprite still has the original's flushed cheeks.

According to Lanchester's square law, when 500 soldiers fight 1,300 under equal conditions, the 500 kill only about 100 before being wiped out. Numerical inferiority is far deadlier than simple subtraction suggests, making [[divide and conquer]] the key strategy in disadvantaged battles.

In March 2026, [[One Piece]] hit 600 million copies sold, so creator [[Eiichiro Oda]] wrote the series' true secret on paper, tore it in half, ran the top half in newspapers, and sank the answer half—sealed in a chest—651 meters into the sea, to be raised only when the story ends.

In [[Greek mythology]], [[Artemis]] was the goddess of both the [[moon]] and childbirth. When a child was born, Greeks offered round [[cake]]s shaped like the moon to thank Artemis — believed to be the origin of eating cake on [[birthday]]s.

[[Moon]] [[Dust|dust]] is razor-sharp. Earth's sand is worn smooth by water and wind, but lunar dust has never been weathered, leaving it jagged like broken glass. Apollo astronauts' suits were visibly abraded within days. Dust control is now a key challenge for [[Artemis program|Artemis]].

In 18th-century Europe, the 'musical [[Dice|dice]] game' (Musikalisches Würfelspiel) was a fad: roll dice to chain written bars into [[Procedural generation|procedurally generated]] [[Music|music]]. 'KV 516f', attributed to [[Wolfgang Amadeus Mozart|Mozart]], can produce about 1.3×10^29 pieces.

[[Piano]] keys were originally reversed from todays layout. In the era of [[Wolfgang Amadeus Mozart|Mozart]] and [[Beethoven]], the wide keys were black and the narrow keys were white. This was likely because [[ivory]], used for white keys, was more expensive than ebony used for black keys.

In [[Switzerland]], owning one [[Guinea pig|guinea pig]] is illegal. A 2008 [[law|animal welfare law]] treats them as social animals and requires at least two. When one dies, businesses even rent out a temporary companion so the survivor isn't left alone.
