This series based on a simple premise, the universe is essentially only how you yourself perceive it. If you change what you know about the universe, then to you, you have essentially changed the universe itself. In this series, James Burke explores nine key moments in the history of the Western world when the introduction of new knowledge and/or technology has led to profound changes in how the West thinks. These include things like the introduction of Guttenberg's printing press, Copernicus's sun centered universe model and Darwin's publishing of his theory of evolution.
