Join Dr Tom Crawford on a tour through the real-world maths behind science fiction and fantasy. Drawing on a decade's research at some of the world's leading universities, he answers all the most bamboozling maths questions raised by Lord of the Rings, Harry Potter, Star Wars and more: from calculating Frodo Baggins' life insurance premium for his journey to destroy the One Ring in the fires of Mount Doom, to establishing how rich Mario would be after he'd collected all those coins. The result is both a dizzying compendium of 'did you know?' facts and a guide to the mathematics of life, the universe and everything. 'The maths teacher we all wish we’d had.'
