The ideas, experiments and inventions of great scientists have revolutionised our understanding of the world. Think of theories such as gravity, evolution by natural selection and the Big Bang, or technologies such as brain scanning and electric motors. This book tells the extraordinary story of 40 of the greatest pioneers of modern science – from Copernicus to Watson and Crick. Organised thematically, it begins at the largest scale, the universe, and moves progressively through smaller spheres – the Earth, molecules and the atom. Beautifully designed and illustrated, The Scientists will intrigue anyone curious to discover how we came to understand the world around us.
