Q0947Identified by Kahneman and Tversky, it shapes how we gamble, invest and hold on to things. We'll often work harder to avoid losing than to gain the same amount.
Q0948Building a shelf, editing a document or cooking a meal can make the result feel more valuable because effort enters the object's story. The attachment can motivate care, but it can also make flawed work harder to judge. Effort gives meaning; meaning can tilt judgement.
Q0950The 'banana equivalent dose' helps explain that tiny radiation exposures are nothing to fear: one banana delivers roughly a ten-thousandth of a chest X-ray. You'd need to eat a wildly impossible number in one sitting to be harmed — and your own potassium-rich body is faintly radioactive too.
Q0952Stars, planets, bodies and phones are made of ordinary matter, but cosmology suggests they are a minority of the cosmic budget. Dark matter helps explain gravitational behaviour, while dark energy is linked to the universe's accelerating expansion. This matters globally because science is honest about what it cannot yet see directly. The lesson: reality is larger than the visible part.
Q0953Ultraweak photon emission is linked to ordinary metabolic processes, not a mystical aura. Sensitive instruments can detect tiny changes, while human vision cannot. This matters because the body is chemically active even when it looks still. The so-what: wonder does not need exaggeration; the real biology is already strange enough.
Q0954Earth's atmosphere scatters shorter wavelengths and changes how sunlight looks from the ground, especially near sunrise or sunset. In space, without that filtering, the Sun's visible light is closer to white. This matters because perception depends on where you stand. The lesson: even the most familiar object changes with context.
Q0955Soil is not dead dust. Bacteria, fungi, archaea and tiny animals help cycle nutrients, build structure and support plant life. The exact count varies by soil, but the scale can be enormous. This matters globally because food systems begin underfoot. The lesson: what looks ordinary may be the infrastructure of life.
Q0957Alexander Bain's design could send images over wires long before voices could travel the same way. The idea simply waited for the world to catch up.
Q0958The label compresses a long series of conflicts over crowns, land and power into one memorable name. It was not one continuous battle for exactly a century. This matters because names make history easier to remember but can blur the shape of events. The lesson: a title is a handle, not the whole story.
Q0959A doctor promoted tomatoes as a cure for ailments, and 'tomato pills' briefly boomed. The fad faded, but the sauce stayed.
Q0960Shipped across the Atlantic in over 200 crates, it was assembled in New York Harbour as a symbol of friendship and freedom.
Q0961Behind glass and crowds, the famous portrait is roughly the size of a large poster. Its power is in subtlety, not scale.
Q0962He worked slowly and sold little, fading into obscurity for two centuries before being rediscovered. Each surviving work is now treasured.
Q0963One of its panels, stolen in 1934, has never been recovered. The masterpiece has survived wars, thefts and even Nazi looting.
Q0966Today it loosely means 'to devastate', but its root is the Latin for a tenth. The original was a literal, grim arithmetic.
Q0967The vivid image captures how a cutting comment is meant to wound. Language often hides such violent origins in everyday words.
Q0968Edison is said to have championed 'hello' as the way to answer a call, over Bell's preferred 'ahoy'. The phone reshaped how we greet each other.
Q0969Filmed in front of the elephants, it was posted by a co-founder. From that humble clip grew the world's biggest video platform.
Q0970It hopped between early networked machines printing 'I'm the creeper, catch me if you can'. A program called 'Reaper' was written to remove it.
Q0971Over time it made rubber boots and cables before moving into electronics and phones. Few companies have reinvented themselves so completely.
Q0973In Plato's Apology, Socrates says this while on trial in Athens in 399 BC, accused of impiety and corrupting the young. He refuses to stop questioning, arguing that self-examination is not a hobby but the condition of a genuinely human life.
Q0975A real circle is always slightly flawed, yet we grasp the idea of a perfect circle. For Plato, those ideals were more real than the physical world.
Q0977He said a writer should not let himself be turned into an institution, and refused all official honours. The committee awarded it anyway.
Q0978Modern dictionaries are usually institutional projects, but Johnson's leaned heavily on one man's reading, definitions and chosen quotations. It didn't freeze English so much as shape how people understood it — a reminder that order itself can be a creative act.
