The Number Seven

Episode two of Another Five Numbers, the BBC radio series presented by Simon Singh.

Picture a gambler. Is it George Clooney, tuxedo ruffled after an all-nighter at a Vegas Black Jack table, or your old Aunt Doris putting down her yearly quid-on-the-nose for the Grand National? Recent research would suggest that it’s neither. Your inveterate gambler is far more likely to be sporting leather patches at their elbows, an unhealthy appetite for corduroy, and a penchant for M-Series rather than Martinis, shaken or stirred. Some mathematicians are putting their mathematical theory where their mouth is and are betting the shirts, stuffed or otherwise, off their backs.

  1. The Number Four

    Episode one of Another Five Numbers, the BBC radio series presented by Simon Singh.

    Simon Singh’s journey begins with the number 4, which for over a century has fuelled one of the most elusive problems in mathematics: is it true that any map can be coloured with just 4 colours so that no two neighbouring countries have the same colour? This question has tested some of the most imaginative minds — including Lewis Carroll’s — and the eventual solution has aided the design of some of the world’s most complex air and road networks.

  2. A Countdown to Zero

    Episode one of Five Numbers, the BBC radio series presented by Simon Singh.

    What’s 2 minus 2? The answer is obvious, right? But not if you wore a tunic, no socks and lived in Ancient Greece. For strange as it sounds, ‘nothing’ had to be invented, and then it took thousands of years to catch on.

  3. 1 — The Most Popular Number

    Episode one of A Further Five Numbers, the BBC radio series presented by Simon Singh.

    Literally, the most popular number, as it appears more often than any other number. More specifically, the first digit of all numbers is a 1 about 30% of the time, whereas it is 9 just 4% of time. This was accidentally discovered by the engineer Frank Benford. It works for all numbers – mountain heights, river lengths, populations, etc.
