The mathematical mistake at the centre of Kate Bush song ‘Pi’I don’t know, I just think that if you’re going to make an entire song about maths, you should probably get the maths right, Kate Bush. Bush dedicating an entire song to a number isn’t all that wild. In her track, ‘Pi’, Bush rounds it up to around 200 or so, though, for the sake of the song. In place of a chorus, she merely reels off the numbers, singing, “3.14159 26535897932 3846 264 338 3279…” The song isn’t just a flex of her mathematical recall, though. To her, it’s a love song.
