And a split second after delivering the punchline of my proof, when a deep idea suddenly becomes almost obvious, I actually saw the ‘light bulb’ go on in his head, and he got so excited that he fell off his chair. And, in a sense, that fleeting moment says it all. FURTHER READING [1] David Acheson (2010). 1089 and all that: A journey into mathematics. Oxford University Press (paperback edition).

The mathematics of messages | 9 CHAPTER 3 Decathlon: The art of scoring points john d. barrow T he decathlon consists of ten track and field events spread over two days. It is the most physically demanding event for athletes. On day one, the 100 metres, long jump, shot put, high jump, and 400 metres are contested. On day two, the competitors face the 110 metre hurdles, discus, pole vault, javelin, and, finally, the 1500 metres. In order to combine the results of these very different events – some give times and some give distances – a points system has been developed.

Now, the theorem is too quirky, I think, to be of any great significance for the future of the world, but it was still the most exciting 45 minutes of my mathematical life, and whenever I talk of that afternoon to young people I like to think that it spurs them on a bit.
