The Shape of Nothing: How the Invention of ‘Zero’ Was a Linguistic and Mathematical Revolution
The concept of zero is more than just a number; it’s a profound linguistic and philosophical idea that had to be invented. This journey traces the word and symbol for zero from its origins as *śūnya* (“void”) in ancient India, through its translation to *ṣifr* in the Arab world, and into Europe where it became both “zero” and “cipher.” By giving a name and a shape to nothingness, we revolutionized mathematics and the very way we talk about absence and potential.
