A mathematician finds another proof for Fermat's last theorem

**David Acheson**? The truth, he says, is that most of them have never been anywhere near it, and that mathematicians could do more to change this perception - perhaps by emphasising the element of surprise that so often accompanies mathematics at its best.

**Navier-Stokes equations**.

**Robert Hunt**concludes our Origins of Proof series by asking what a proof really

*is*, and how we know that we've actually found one. One for the philosophers to ponder...
