We have never had so much information at our fingertips, and yet most of us simply don't understand how our world really works. Professor Vaclav Smil is not a pessimist or an optimist, he is a scientist, and this book is a much-needed reality check on topics ranging from food production and nutrition, through energy and the environment, to globalisation and the future. For example, the carbon footprint of meat is well known, but did you know that the equivalent of five tablespoons of diesel fuel goes into the production of each greenhouse-grown, medium-size, supermarket-bought tomato?

When was the last time you read a grand statement, accompanied by a large number and wondered whether it could really be true? Statistics are vital in helping us tell stories - we see them in the papers, on social media and we hear them used in everyday conversation - and yet we doubt them more than ever.

Now, he wants to apply it to how we study everything else.
