Alex Bellos has made another documentary for BBC Radio 4, this time about the number zero. It’s a pleasant bit of numerical tourism, as Alex travels to India to find the source of the number zero in a small shrine, with a diversion to talk about Vedic maths along the way.
You can listen to Nirvana by Numbers on the BBC iPlayer. It looks like it’s available indefinitely. If Alex has whetted your appetite for historical zeroes, the book Zero: The Biography of a Dangerous Idea by Charles Seife is a cracking read.
