## Our paper inspires equations appearing in hit TV series, Rick and Morty

Rick tells Morty, “That book has everything they need to create snake time travel” set to a backdrop containing markings reminiscent of odd hieroglyphics on a chalkboard. These markings are actually redrawn from diagrammatic equations appearing in Jacob Biamonte’s book, Quantum Tensor Networks. For reasons described in the book, certain classes of equations admit a formal diagramatic calculus. The equations appearing on the board prove what is known as the “snake equation”. This is fitting since Rick and Morty, Season 4: Episode 5, “Rattlestar Ricklactica” was centred around snakes that invent time travel. When asked about the situation, Biamonte said: “So what if they copied the equations down wrong, Rick and Morty is the best thing to[…]
