Notas del episodio

Remember that dreaded figure your teacher scrawled on the margin of your math test paper? It’s the hero of this episode.

Our much-villainised zero has a fascinating history. The Babylonians, as we discovered in Episode 1 (Babylon), may have arrived at a placeholder for zero, but the actual symbol did not enter convention until the 7th century in the Indian subcontinent. It later became a foundational element of mathematical concepts during the Islamic Golden Age (the word algebra has Arabic roots). Later, it was adopted in Europe by Renaissance mathematicians.

Long story short: Zero has come full circle.

In this episode, Divakaran and Shraddha host you through the evolution of zero through the ages.
