🔺️ Today is March 14 (3.14) and it's Pi Day! The π is the irrational number that describes the relationship between a circle’s circumference and its diameter. No matter the size of the circle, that ratio is always about 3.14.
What makes π fascinating is that its digits go on forever without repeating. Because of this, mathematicians call π a transcendental number, meaning it cannot be neatly expressed using ordinary algebra.
For centuries, mathematicians tried to solve a famous puzzle called “squaring the circle”—drawing a square with exactly the same area as a circle using only a compass and straightedge. In 1882, mathematicians proved that this task is mathematically impossible, because π is transcendental.
Sometimes mathematics doesn’t just give answers, it tells us which questions cannot have one.
