Smart answers to silly questions: Randall Munroe reveals all

PRAISE FOR WHAT IF? 2

Randall Munroe [is] the guru of absurd science questions . . . What If ?2 is stuffed with questions that are fanciful in the asking, but perfectly - and playfully - informative in the answering. The questions throughout are equal parts brilliant, gross, and wonderfully absurd and the answers are thorough, deeply researched, and great fun. Do you need any of this information? No. Are you happy - indeed, delighted - to have it? Almost certainly yes. Science isn't easy, but in Munroe's capablehands, it surely can be fun. (Jeffrey Kluger)

One of my favourite books of the year. (Tim Harford)

Head-scratching . . . seemingly simple conundrums lead to the most fascinating of rabbit holes.

*Staff's Favourite Books of 2022* A dense litany of thoroughly researched explanations of intensely silly hypotheticals. Perfect if you enjoy it when stuffy figures of authority crack a smile. Or if you like it when black holes form. That happens a lot.
