Adam Spencer is a famous Australian media personality and public mathematician. He likes to describe himself as “nowhere near Australia’s best mathematician – but possibly it’s best known”. Adam was completing a PhD in Pure Mathematics at the University of Sydney when he won a national Raw Comedy championship with Triple J, Australia’s youth radio station. He then went to become one of Australia’s most respected, wittiest and thought provoking breakfast radio commentators across Triple J and later ABC 702. His dexterity at being both mathematical – he has authored 7 best-selling books for talented maths students – and verbal – he was voted best debater in the world at the 1996 World Championships – makes him a curious customer indeed. Adam is currently the Ambassador for Science and Mathematics at the University of Sydney, and his next book, Maths 101, for Dumb Dads and Desperate Mums, was released in December 2021 by Hardie Grant.
