One pupil, Tom Whitmore, 15, from Brighton, acknowledged that Big Bang Theory had contributed to his decision, with a number of classmates, to consider physics at A-level, and in causing the subject to be regarded as “cool”. “The Big Bang Theory is a great show and it’s definitely made physics more popular. And disputes between classmates now have a new way of being settled: with a game of rock, paper, scissors, lizard, Spock,” he said.

Experts at the Institute of Physics (IoP) also believe the series is playing a role in increasing the number of physics students. Its spokesman, Joe Winters, said: “The rise in popularity of physics appears to be due to a range of factors, including Brian’s public success, the might of the Large Hadron Collider and, we’re sure, the popularity of shows like The Big Bang Theory.”
