This is just one of the questions that Honours (Pure Maths) student Peter Ayre was subjected to in his interview. We get the scoop on his highlights – and challenges – of doing Honours, his plans for after uni, and why maths continues to engage and motivate him.

An exponential sum is obtained by adding up certain types of complex numbers. Such sums are used in the solution of various problems in number theory. When the sums are plotted in the complex plane, the resulting plot can be very intricate and beautiful.

This article explores some features of exponential sums and their graphs... just for fun.
