History
Sunglasses Before the Fashion Statement
Sunglasses didn’t start as a fashion flex; they started as a practical fix. Long before Ray-Bans and runways, people were shielding their eyes from glare with whatever worked: Inuit communities used carved snow goggles to cut blinding reflected light, and in 12th-century China, smoky quartz lenses helped judges conceal their expressions in court. Modern sunglasses took off in the 20th century as mass-produced tinted lenses became affordable and pilots needed better glare protection in the air.

Baking Soda
NaHCO3
Is the chemical compound for sodium bicarbonate, better known as baking soda. It's a white crystalline powder that's mildly alkaline. When heated or mixed with an acid (like vinegar or lemon juice), it releases carbon dioxide gas, which is why it's commonly used in baking to help dough rise.

The Humble Wheelie Bin
The wheelie bin is one of those quiet inventions that changed daily life by changing the handle: instead of lifting heavy rubbish containers, you could simply roll them to the kerb—making household collection faster, cleaner, and far less punishing on the body. The modern design is widely traced to Slough in the UK, where Frank Rotherham Mouldings created a wheeled bin in 1968 and the concept rapidly proved its value well beyond the factory floor.
Did you know? The “wheelie bin” as we recognise it today is often dated to 12 March 1968—and it wasn’t originally designed for kerbside rubbish at all, but for moving waste around a factory.

Australia II?
Australia II’s 1983 America’s Cup win wasn’t just a sailing result — it was a national shockwave that ended 132 years of U.S. dominance and turned a yacht race into instant Australian folklore. Skipper John Bertrand and his crew pulled off a tense comeback in the decider, powered by smart tactics and a boat that arrived with genuine innovation. The celebration was so big that Prime Minister Bob Hawke famously told the country that any boss who sacked someone for not showing up that day was “a bum” — effectively giving everyone permission to take the day off.
Did you know? Australia II’s “winged keel” was so controversial that rivals challenged its legality — and it still raced on to win.

More Than Just Words
Charles Dickens’ “A Christmas Carol” did more than introduce Scrooge—it helped cement many of the “modern” Christmas themes we now take for granted in English-speaking culture: generosity, family warmth, and social conscience wrapped in an irresistible ghost story.
Did you know? The book was published on 19 December 1843, and its first print run of 6,000 copies reportedly sold out by Christmas Eve.
Entertainment
How Did You Come up with That?
James Cameron has said the core visual inspiration for Avatar came from a dream he had at 19—especially a glowing, bioluminescent forest and strange alien creatures, imagery he later built into Pandora. Story-wise, he framed it as an old-school sci-fi “jungle adventure,” influenced by the adventure and science-fiction books he grew up reading, while grounding the themes in environmentalism and the historical pattern of colonisation and resource exploitation. He’s also linked the title “avatar” to the idea of an incarnation taking physical form—mirrored in the film’s concept of humans operating Na’vi bodies.
