The latest edition in the Economist Explainer series, edited and introduced by Deputy Editor Tom Standage

The more we ponder, the odder the world can seem. How do footballers get their shirt numbers? Why does having daughters make couples more likely to divorce? How do you move a horse from one country to another? What counts as a journey into space? The keen minds at The Economist contemplate all these questions and more in their quest for the globe's most extraordinary quandaries and conundrums, with bizarre facts and headscratchers that show the world is even stranger than we might have thought. From plant-based milk and supermoons to the next Dalai Lama and what really happened at the storming of the Bastille, this collection of the oddest and most mindboggling explanations will amaze and delight in equal measure.
