What is zero? How did it come about? Hannah Fry tells the story of how zero went from nothing to something.
Once upon a time, zero wasn’t really a number. Its journey to the fully fledged number we know and love today was a meandering one. Today, zero is both a placeholder, and tool, within our number system signifying an absence of a value, and as a number in its own right. Animated by Andrew Khosravani
