Melvyn Bragg and guests discuss random and pseudorandom numbers. Randomness will be familiar to anybody who’s bought a lottery ticket or shuffled a pack of cards. But there’s also a phenomenon known as pseudo-randomness –numbers which look random but aren’t. So why are these numbers useful and how can they be generated? Melvyn is joined by Marcus du Sautoy, Professor of Mathematics at the University of Oxford; Colva Roney-Dougal, Senior Lecturer in Pure Mathematics at the University of St Andrews; and Timothy Gowers, Royal Society Research Professor in Mathematics at the University of Cambridge.

George Dyson | Turing’s Cathedral: The Origins of the Digital Universe
In the 1940s and 1950s, a group of brilliant engineers led by John von Neumann gathered in Princeton, New Jersey with the joint goal of realizing Alan Turing’s theoretical universal machine-a thought experiment that scientists use to understand the limits of mechanical computation. As a result of their fervent work, the crucial advancements that dominated 20th century technology emerged. In Turing’s Cathedral, technology historian George Dyson recreates the scenes of focused experimentation, mathematical insight, and creative genius that broke the distinction between numbers that mean things and numbers that do things-giving us computers, digital television, modern genetics, and models of stellar evolution. Also a philosopher of science, Dyson’s previous books include Baidarka, Darwin Among the Machines, and Project Orion. (recorded 3/13/2012)

Adventures in Numberland
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.

Simple as Pi
Episode two of Five Numbers, the BBC radio series presented by Simon Singh.
Most people’s first slice of Pi is at school where it is generally made palatable as either 3.14 or the fraction 3 1/7. The memory of this number may be fuzzy for those propelled through their Maths GCSE by the power of Casio (where Pi was reduced to a button on the bottom row of the calculator), but the likelihood is they still recall that romanticised notion of a number whose decimal places randomly go on forever. At its simplest, Pi is the ratio of the circumference of a circle to its diameter. At its most complex, it is an irrational number that cannot be expressed as the ratio of two whole numbers and has an apparently random decimal string of infinite length.
