# Maths visit by University Professor

On Tuesday 7 June Professor David Bryant from the University of Otago gave an interactive talk about mathematical modelling to 15 interested students.

With David's assistance, students tackled problems such as, *How thick is cling film? How long is the spaghetti in a tin of spaghetti? *and the age old problem of *How long is a piece of string (in the world's largest ball of string)?* Instead of using complicated mathematics, students were encouraged to use the simplest mathematics possible to find a reasonable approximation of the answer to these questions. And so armed with a raspberry spring roll, a tin of spaghetti tipped out on a plate, and formulae for the area of a circle, the area of a rectangle, the volume of a cylinder, and the volume of a sphere, students successfully solved these problems in under an hour!
