A fascinating collection of the most significant plans, sketches, drawings and illustrations that have changed the way we think about the world. From primitive cave paintings to the complicated DNA double helix drawn by Crick and Watson, they chart dramatic breakthroughs in our understanding of the world and its history. This fascinating book encompasses everything from the triple spirals found on prehistoric megalithic tombs dating right up to the drawings sent out on the side of space exploration probes. Discover Leonardo da Vinci's beautiful technical drawings, pre-empting the invention of manned flight, Copernicus's bold diagrams that dared to tell us that Earth was not at the centre of the Universe, as well as the history of the more everyday diagrams that we now take for granted. Every diagram is clearly illustrated and placed into context with very accessible text even for the lay reader.
