Melvyn Bragg and guests discuss the 19th century mathematician Ada Lovelace. Deep in the heart of the Pentagon is a network of computers. They control the US military, the most powerful army on the planet, but they are controlled by a programming language called Ada. It’s named after Ada Lovelace, the allegedly hard drinking 19th century mathematician and daughter of Lord Byron. In her work with Charles Babbage on a steam driven calculating machine called the Difference Engine, Ada understood, perhaps before anyone else, what a computer might truly be. As such the Difference Engine is the spiritual ancestor of the modern computer.Ada Lovelace has been called many things - the first computer programmer and a prophet of the computer age – but most poetically perhaps by Babbage himself as an ‘enchantress of numbers’.With Patricia Fara, Senior Tutor at Clare College, Cambridge; Doron Swade, Visiting Professor in the History of Computing at Portsmouth University; John Fuegi, Visiting Professor in Biography at Kingston University.

Melvyn Bragg and guests discuss King Lear. Around the turn of 1606, a group of London theatre-goers braved the plague to take in a new play by the well-known impresario, Mr William Shakespeare. Packed into the Globe Theatre, they were treated to a tale of violence, hatred and betrayal so upsetting that it thereafter languished among Shakespeare’s less popular plays.The story of Lear – of a man who divides up his property and loses the love of a daughter - is an ancient and ultimately happy one. But in the hands of William Shakespeare it became a shocking and violent vision of a broken family in a godless universe. So shocking that after the playwright’s death it was shunned and rewritten with a happy ending. Only in the 19th and 20th centuries did Shakespeare’s bleak, experimental and disorientating drama attain the status it has now. But why did Shakespeare take a story from the deep history of Britain and make it so shockingly his own and when, from the Civil War to the Second World War, did this powerful and confusing tragedy emerge as Shakespeare’s greatest?

Melvyn Bragg and guests will be leaving the studio, the planet and indeed, the universe to take a tour of the Multiverse. If you look up the word ‘universe’ in the Oxford English Dictionary you will find the following definition: “The whole of created or existing things regarded collectively; all things (including the earth, the heavens, and all the phenomena of space) considered as constituting a systematic whole.” That sounds fairly comprehensive as a description of everything, but for an increasing number of physicists and cosmologists the universe is not enough. They talk of a multiverse – literally many universes – to explain aspects of their theory, the character of the universe and the riddle of our existence within it. Indeed, compared to the scope and complexity of the multiverse, the whole of our known reality may be as a speck of sand upon a beach.The idea of a multiverse is still controversial, some argue that it isn’t even science, because it is based on an idea that we may never be able to prove or even see. But what might a multiverse be like, why are physicists and cosmologists increasingly interested in it and is it really scientific to discuss the existence of universes we may never know anything With Martin Rees, President of the Royal Society and Professor of Cosmology and Astrophysics at the University of Cambridge; Fay Dowker, Reader in Theoretical Physics at Imperial College; Bernard Carr, Professor of Mathematics and Astronomy at Queen Mary, University of London
