Like The Simpsons? Like maths? Or even a bit apathetic about maths but like geeky in-jokes? Then this event is for you.
It isn't happening until October but about half the seats are already gone, so we thought we'd better flag it up now. Simon Singh's written a book about the maths inside The Simpsons – it's not released until 29 October, but a week earlier he's at the Southbank Centre talking about it. You might not think there's much maths in the 25 series, but the references range from Maggie building "EMCSQU" with blocks to P versus NP in Treehouse of Horror VI. Why? Because several of the writers have hardcore maths (or "math") qualifications.
We'd tell you more, but Simon can probably explain it better.
Simon Singh: The Simpsons and Their Mathematical Secrets takes place on 22 October, 7.45pm, in The Purcell Room at Southbank Centre. Tickets are £10. To book see the Southbank Centre website.
