In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and guests discuss the largest and arguably the most astonishing religious structure on Earth, built for Suryavarman II in the 12th Century in modern-day Cambodia. It is said to have more stone in it than the Great Pyramid of Giza, and much of the surface is intricately carved and remarkably well preserved. For the last 900 years Angkor Wat has been a centre of religion, whether Hinduism, Buddhism or Animism or a combination of those, and a source of wonder to Cambodians and visitors from around the world.WithPiphal Heng Postdoctoral scholar at the Cotsen Institute and the Programme for Early Modern Southeast Asia at UCLAAshley Thompson Hiram W Woodward Chair of Southeast Asian Art at SOAS University of LondonAndSimon Warrack A stone conservator who has worked extensively at Angkor WatProducer: Simon Tillotson

Melvyn Bragg and guests discuss the celebrated Welsh poet, Dylan Thomas (1914 - 1953). He wrote some of his best poems before he was twenty in the first half of his short, remarkable life, and was prolific in the second half too with poems such as those set in London under the Blitz and reworkings of his childhood in Swansea, and his famous radio play Under Milk Wood (performed after his death). He was read widely and widely heard: with his reading tours in America and recordings of his works that sold in their hundreds of thousands after his death, he is credited with reviving the act of poetry as performance in the 20th century.WithNerys Williams Associate Professor of Poetry and Poetics at University College DublinJohn Goodby Professor of Arts and Culture at Sheffield Hallam UniversityAndLeo Mellor The Roma Gill Fellow in English at Murray Edwards College, University of CambridgeProducer: Simon Tillotson

Melvyn Bragg and guests discuss the abrupt transformation of stars after shining brightly for millions or billions of years, once they lack the fuel to counter the force of gravity. Those like our own star, the Sun, become red giants, expanding outwards and consuming nearby planets, only to collapse into dense white dwarves. The massive stars, up to fifty times the mass of the Sun, burst into supernovas, visible from Earth in daytime, and become incredibly dense neutron stars or black holes. In these moments of collapse, the intense heat and pressure can create all the known elements to form gases and dust which may eventually combine to form new stars, new planets and, as on Earth, new life.The image above is of the supernova remnant Cassiopeia A, approximately 10,000 light years away, from a once massive star that died in a supernova explosion that was first seen from Earth in 1690WithMartin Rees Astronomer Royal, Fellow of Trinity College, CambridgeCarolin Crawford Emeritus Member of the Institute of Astronomy and Emeritus Fellow of Emmanuel College, University of CambridgeAndMark Sullivan Professor of Astrophysics at the University of SouthamptonProducer: Simon Tillotson
