Melvyn Bragg and guests discuss the culture of the Baroque. What do the music of Bach, the Colonnades of St Peter’s, the paintings of Caravaggio and the rebuilding of Prague have in common? The answer is the Baroque – a term used to describe a vast array of painting, music, architecture and sculpture from the 17th and 18th centuries.Baroque derives from the word for a misshapen pearl and denotes an art of effusion, drama, grandeur and powerful emotion. Strongly religious it became the aesthetic of choice of absolute monarchs. But the more we examine the Baroque, the more subtle and mysterious it becomes. It is impossible to discuss 17th century Europe without it, yet it is increasingly hard to say what it is. It was coined as a term of abuse, denounced by thinkers of the rational Enlightenment and by Protestant cultures which read into Baroque the excess, decadence and corruption they saw in the Catholic Church.

Melvyn Bragg and guests discuss Vitalism, an 18th and 19th century quest for the spark of life. On a dreary night in November 1818, a young doctor called Frankenstein completed an experiment and described it in his diary: “I collected the instruments of life around me, that I might infuse a spark of being into the lifeless thing that lay at my feet…By the glimmer of the half-extinguished light, I saw the dull yellow eye of the creature open…”Frankenstein may seem an outlandish tale, but Mary Shelley wrote it when science was alive with ideas about what differentiated the living from the dead. This was Vitalism, a belief that living things possessed some spark of life, some vital principle, perhaps even a soul, that distinguished the quick from the dead and lifted them above dull matter. Electricity was a very real candidate; when an Italian scientist called Luigi Galvani made dead frogs twitch by applying electricity he thought he had found it. Vitalists aimed at unlocking the secret of life itself and they raised questions about what life is that are unresolved to this day.

Melvyn Bragg and guests discuss an iconic piece of 20th century maths - Gödel’s Incompleteness Theorems. In 1900, in Paris, the International Congress of Mathematicians gathered in a mood of hope and fear. The edifice of maths was grand and ornate but its foundations, called axioms, had been shaken. They were deemed to be inconsistent and possibly paradoxical. At the conference, a young man called David Hilbert set out a plan to rebuild the foundations of maths – to make them consistent, all encompassing and without any hint of a paradox. Hilbert was one of the greatest mathematicians that ever lived, but his plan failed spectacularly because of Kurt Gödel. Gödel proved that there were some problems in maths that were impossible to solve, that the bright clear plain of mathematics was in fact a labyrinth filled with potential paradox. In doing so Gödel changed the way we understand what mathematics is and the implications of his work in physics and philosophy take us to the very edge of what we can know.With Marcus du Sautoy, Professor of Mathematics at Wadham College, University of Oxford; John Barrow, Professor of Mathematical Sciences at the University of Cambridge and Gresham Professor of Geometry and Philip Welch, Professor of Mathematical Logic at the University of Bristol.
