Looking: Examines the way we see and the influence it has on what we understand. By tracing the development of Galileo’s telescope and using compelling demonstrations, Morrison shows how instruments have been central to the development of scientific theories through the ages.

For just as the naked eye can be tricked, so too can the sophisticated instruments we develop to amplify the power of our unaided senses.
