Go Figure: Things You Didn't Know You Didn't Know brings together for the first time the very best explainers and charts, written and created by top journalists to help us understand such brain-bending conundrums as why almost half the population of Korea has one of two surnames, how bitcoin mining works, and the seasonal distribution of dog poo on the streets of New York. Subjects both topical and timeless, profound and peculiar, are explained with The Economist trademark wit and verve.
