Science and illustration have always walked hand in hand, and not only the scientific community but the general public as well have used images since early history to understand natural phenomena. Moreover, from Galileo to Einstein, our modern history has been written with the key support of art and with all the insights it contributes. This XL-sized book collects more than 300 graphic works that range from original sketches to technical drawings, and from meticulous hand illustrations to computer-generated images.
