Mathematician Marcus Du Sautoy, not surprisingly has a fascination with numbers, and he has unleashed the hidden power of them on his amateur football team, Recreativo Hackney. Eight years after noticing that all of Real Madrid's better players wore prime-number shirts ("Carlos was number 3, Zidane number 5, Raoul number 7, and Beckham number 7" he told the Daily Telegraph) he persuaded Recreativo Hackney to do the same.
The next season with shirts ranging from No2 to No 43 they were promoted, proving that that even maths professors have lucky numbers - Du Sautoy wore number 17.
