The Day the Universe Changed

The Day the Universe Changed: A Personal View by James Burke is a British documentary television series written and presented by science historian James Burke, originally broadcast on BBC1 from 19 March until 21 May 1985 by the BBC. The series' primary focus is on the effect of advances in science and technology on western society in its philosophical aspects. 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. In the United States, the ten-week hour-long series was broadcast from 13 October to 15 December 1986, on PBS and was rebroadcast on The Learning Channel in 1993.A 1985 companion book of the same title, also written by Burke, presenting the same general premise of the television series in expanded detail. Burke read from the book for an abridged audiocassette and compact disc set available from Macmillan Audio.
