I was watching an early episode of the British comedy series Cold Feet recently. In one episode one of the characters has an urgent need for a condom. He runs into the local pub and into the men's. For about a couple of seconds we see that one wall of the toilets is completely covered in mathematics. I didn't have time to register exactly what it was though the prevalence of psis made me think it was something involving the Schrodinger equation. Unfortunately I didn't get around to rewinding to check what it was. This is a pretty weird place to find a bunch of mathematics in a sitcom. Did anyone else spot this? Anyone know of any weirder sightings of mathematics on TV? Anyone out there at all?
