Sometimes the most innocent questions are the hardest to answer. Is the earth really round? Did Christopher Columbus really discover America? Does three plus eight always make eleven? How do you know? How do you know anything? This is a light-hearted, stimulating and provocative journey through the jungles of fact and fiction, knowledge and wisdom, and an invitation for you to learn to think for yourself. Are you the victim of other people's thinking? How can you be sure?

This is a wonderful non-fiction book from the Cold Fusion series, which offers deep insights to inquiring minds in a way that is simple yet not patronising. Light-hearted, stimulating and entertaining, this book will answer at least some of the questions that a curious child wants to know the answers to. .
