Srinivasa Ramanujan's life, discoveries, and verified quirks: divine formula dreams, the taxi-cab number 1729, near-starvation in Cambridge, and dying at 32.

Not all infinities are equal. Georg Cantor proved that some infinite sets are larger than others — a discovery so strange it drove mathematicians mad.

Prime numbers seem like a curious curiosity from school math. They're actually the foundation of every secure transaction on the internet — and one of the deepest mysteries in mathematics.

A margin note scribbled in the 1630s baffled the world's greatest mathematicians for 358 years. Here's how it was finally cracked.

The largest known prime number has 41,024,320 digits. Finding it took a rented cloud of data-center GPUs and a decades-old search project. But what is the point of a number nobody will ever write out?
