I can honestly say that this book changed my life and the way I think about both maths and physics. If you’re a science wannabe like me, this book is gentle enough that you can grasp the big concepts. But if you’re a bit more hardcore, you’ll be glad it doesn’t baby the more difficult ideas.
However, the reason I most love this book is that it’s also a book full of love. Love for Turing, love for the beauty of nature but also love of love itself. Inevitably, it is tragic in parts but overall, it’s a celebration of the life of a brilliant gay man who helped defeat world fascism and whose ideas define huge parts of the world we live in now.
