The first and second pilots of The Big Bang Theory were directed by, who did not continue with the show.

We worked hard to get all the science right.' David Saltzberg, who has a Ph.D. In physics, has served as the science consultant for the show for six seasons and attends every taping.
He saw early versions of scripts which needed scientific information added to them, and he also pointed out where the writers, despite their knowledge of science, have made a mistake.

Single cover for 'Big Bang Theory Theme' by (2007)The Canadian band wrote and recorded the show's theme song, which describes the history and formation of the universe and the Earth. Co-lead singer was asked by Lorre and Prady to write a theme song for the show after the producers attended one of the band's concerts in Los Angeles.
By coincidence, Robertson had recently read 's book, and at the concert improvised a freestyle rap about the origins of the universe. Lorre and Prady phoned him shortly thereafter and asked him to write the theme song. Having been asked to write songs for other films and shows, but ending up being rejected because producers favored songs by other artists, Robertson agreed to write the theme only after learning that Lorre and Prady had not asked anyone else. On October 9, 2007, a full-length (1 minute and 45 seconds) version of the song was released commercially.
Although some unofficial pages identify the song title as 'History of Everything,' the cover art for the single identifies the title as 'Big Bang Theory Theme.' A music video also was released via special features on The Complete Fourth Season DVD and Blu-ray set. The theme was included on the band's greatest hits album, released on September 27, 2011.

The duo, who were looking to have salary parity with Parsons, Galecki, and Cuoco, signed their contracts after the studio and producers threatened to write the characters out of the series if a deal could not be reached before the start of production on season eight.
