You know that you are at a party full of geeks when:
- The music goes off suddenly, because the network that was streaming music off the web goes down. Half a dozen PhD students dash to help to try and fix the network;
- The silence is punctured by the sound, from the next room, of half-a-dozen stoned physicists having a rambling argument about the theory of relativity;
- Meanwhile, two people are sat in front of me playing chess, and taking a swig from a bottle of vodka whenever a piece is taken.
