Matt Parker (in addition to organising the next MathsJam) has just published a column in the *Guardian* about How to win a million dollars with maths.

This is the first column in Matt's series on the seven Millennium Prize Problems posed by the Clay Institute. It's an excellent introduction to the Riemann Hypothesis and he also reveals the intriguing fact: All prime numbers (greater than five) squared are one more than a multiple of 24. Hmmm...

We're looking forward to the next column in the series! And in the meantime you can also read more about the Millennium Prize Problems and the Riemann Hypothesis on *Plus*.
