“The title comes from the philosophical idea that the universe essentially only exists as one perceives it through what one knows; therefore, if one changes one’s perception of the universe with new knowledge, one has essentially changed the universe itself. To illustrate this concept, James Burke tells the various stories of important scientific discoveries and technological advances and how they fundamentally altered how western civilization perceives the world. The series runs in roughly chronological order, from around the beginning of the Middle Ages to the present.” —Wikipedia
