There’s no such thing as a silly question

Here is a silly question-and-answer book, fact-checked by world-leading experts from across the University of Cambridge. Did you know that there’s no set number of bones in the human body? Most babies are born with around 300 bones, but by the time they’ve grown up, they usually have between 206 and 213. Covering a range of subjects from science, technology, engineering and mathematics to evolution, zoology, social history and more, this hilarious yet clever book expertly answers 213 of the most unusual and interesting questions you never thought to ask about the world – one for at least every bone in your body!
