Former child prodigy Terence Tao has become one of the world’s greatest living mathematicians. At 24 he became the youngest person ever appointed full professor at UCLA, and at the tender age of 31 he was awarded mathematics’ highest honour, the Fields Medal.
Back in his childhood home of Australia, he visited the ANU to deliver this fascinating talk about one of his favourite subjects, prime numbers.

Episode one of Another Five Numbers, the BBC radio series presented by Simon Singh.
Simon Singh’s journey begins with the number 4, which for over a century has fuelled one of the most elusive problems in mathematics: is it true that any map can be coloured with just 4 colours so that no two neighbouring countries have the same colour? This question has tested some of the most imaginative minds — including Lewis Carroll’s — and the eventual solution has aided the design of some of the world’s most complex air and road networks.

An ancient Egyptian papyrus from around 1550 BC, used to train scribes. It contains 84 different calculations to help with various aspects of Egyptian life, from pyramid building to working out how much grain it takes to fatten a goose. Neil MacGregor, Director of the British Museum, looks at man’s early experiments with numbers and discovers how the Egyptians’ understanding of mathematics enabled them to build a state machine, which could manage food supplies and even compute the flood levels of the Nile.

Episode four of Five Numbers, the BBC radio series presented by Simon Singh.
The imaginary number takes mathematics to another dimension. It was discovered in sixteenth century Italy at a time when being a mathematician was akin to being a modern day rock star, when there was ‘nuff respect’ to be had from solving a particularly ‘wicked’ equation. And the wicked equation of the day went like this: "If the square root of +1 is both +1 and -1, then what is the square root of -1?"

Melvyn Bragg is joined by Roger Penrose, Basil Hiley and Simon Saunders to discuss the bizarre nature of atoms and the conundrum at the heart of quantum physics
The measurement problem arises because we don’t really understand how the atoms that constitute our world behave. They are fundamentally mysterious to us, even shocking, and they defy our attempts to measure and make sense of them. Possible solutions range from the existence of multiple realities to the rather more mundane possibility of an error in our mathematics - but a solution, if found, could transform our understanding of reality.

Join author and journalist Alex Bellos for a surprising and entertaining look at the world of mathematics.
By bringing together history, reportage and mathematical proofs, and covering subjects from adding to algebra, from set theory to statistics, and from logarithms to logical paradoxes, Alex Bellos reveals how mathematical ideas underpin just about everything in our lives.
Join Alex Bellos at the RSA to discover the beauty of mathematical patterns in nature, the peculiar predictability of random behaviour, how to win at the casino, the deep connections between maths, religion and philosophy, and why the best Scrabble players are mathematicians.
Speaker:Alex Bellos, writer, broadcaster and author of Futebol, the Brazilian Way of Life (Bloomsbury, 2002) and Alex’s Adventures in Numberland (Bloomsbury, 2010).
Chair:Matthew Taylor, chief executive, RSA.
