Stories

• Russell's Paradox (Logic, 1901): The set of all sets that don't contain themselves. Does it contain itself?
• Schrödinger's Cat (Physics, 1935): A cat, a box, and a letter from Einstein. Alive and dead until you look.
• The Monty Hall Problem (Probability, 1990): Switch doors or stay? A game show puzzle that fooled a thousand PhDs.
• Hilbert's Infinite Hotel (Mathematics, 1924): Every room is full. A new guest arrives. No problem. Then a bus pulls up with infinitely many more.
• The Birthday Paradox (Probability, 1939): Put 23 people in a room and it's a coin flip that two share a birthday. Really.
• Galileo and the Falling Bodies (Physics, 1589): Does a bowling ball fall faster than a feather? Aristotle said yes. It took 2,000 years and a trip to the Moon to settle it.
• Eratosthenes Measures the Earth (Astronomy, c. 240 BC): Two sticks, one shadow, and the size of the planet, 2,200 years before satellites.
• Mendel's Peas (Biology, 1865): A monk, 28,000 pea plants, and a 3-to-1 ratio nobody noticed for 34 years.
• The Seven Bridges of Königsberg (Mathematics, 1736): Can you cross all seven bridges exactly once? A Sunday stroll that invented graph theory.
• Conway's Game of Life (Computer Science, 1970): Three rules, a grid of squares, and no players. Then it builds a computer.
