The Big Bang Theory
CBS has a physics professor on the set of The Big Bang Theory to proofread and fact-check the scripts. In addition to making sure everything is scientifically accurate, he sometimes adds some humor to the whiteboard that sits in Leonard and Sheldon’s apartment. For instance, in the episode “The Jiminy Conjecture,” two of the characters get into an argument about a cricket. In the background, the whiteboard features Dolbear’s law, a formula that explains the relationship between temperature and the rate at which crickets chirp. The information on the board doesn’t get referenced much; it’s mostly for science enthusiasts to enjoy.
