Board 2 · the game

Rock, paper, scissors,
lizard, Spock.

Five hands, ten rules, ten real places. Sheldon explains the game on the show; Sam Kass and Karen Bryla invented it. Whichever rule wins picks where you go next.

UCLA

David Saltzberg, a UCLA physics professor, was the show’s science consultant from 2007: he checked the whiteboards and filled script gaps marked “Insert Science Here”. In 2015 the cast and crew created the first scholarship endowment at UCLA made by a television series; by 2019 the show had raised $5.5 million. A $24.5 million pledge from the Chuck Lorre Family Foundation later grew it into the UCLA Chuck Lorre Scholars Program.

Royal Swedish Academy of Sciences

On 8 October 2019 the academy opened its physics prize announcement with a nod to the show’s theme song, which academy member Ulf Danielsson quoted. Its secretary general, Göran Hansson, called the show a fantastic achievement for bringing science to viewers round the world. The finale, that May, had Sheldon and Amy win the Nobel Prize in physics.

Vasquez Rocks

In “The Bakersfield Expedition” the four stop at Vasquez Rocks in Star Trek: The Next Generation uniforms on the way to a comic convention, and their car is stolen. SCV News reported in January 2013 that the scene was shot on Stage 5 at Warner Bros. in Burbank, and that the episode drew 19.78 million viewers. Joyn’s guide tells it differently: the four actors left the studio for an outdoor shoot at the park. The 945-acre county park has been used in many films, television shows and commercials.

A county park of 945 acres: walk among the rocks; the interpretive centre has water during its opening hours.

The city it borrowed.

Pasadena references run all through the scripts. The show was taped down the road in Burbank; Pasadena gave it a day, an alley and, at the end, a free screening.

Big Bang Theory Alley

Pasadena dedicated a street to the show in Old Pasadena: Big Bang Theory Alley, parallel to Raymond Avenue and Arroyo Parkway between Holly Street and Green Street. The city made 25 February “The Big Bang Theory Day” in 2016, for the 200th episode. Councilmember Andy Wilson read the proclamation on 20 February 2016, with the seven stars and Chuck Lorre, Steven Molaro and Bill Prady there.

Caltech campus

Caltech describes the show as centred on a group of Caltech physicists who are friends and roommates. The campus covers 124 acres; Visit Pasadena says it was planned as a mix of architectural styles, from Mediterranean to Brutalist. Volunteer tours walk it on Thursday 22 October and Thursday 19 November 2026, at 10.30am.

An open campus: walk in, keep to the paths, and leave labs and student houses alone.

The Athenaeum, Caltech

Caltech says “The Hawking Excitation”, in season five, was filmed at the Athenaeum. Visit Pasadena calls it a Mediterranean-style landmark on the corner of California and Hill; access is generally for members and their guests. Caltech’s volunteer history and architecture tours start at its entrance, 551 South Hill Avenue.

Hollywood Walk of Fame

Kaley Cuoco’s star, the 2,532nd, is at 6621 Hollywood Boulevard near Whitley Avenue; she asked for it to sit near John Ritter’s. Jim Parsons received star number 2,545 in March 2015, with Chuck Lorre at the ceremony. Kaley Cuoco and Johnny Galecki came to see Parsons get his; Lorre told him he had done something beyond imagination.
