In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and guests discuss the life and work of John Ruskin. He was the most brilliant art critic of his age, perhaps the most brilliant that Britain has ever produced, but he was much more than that. A champion of Turner and an enemy of Whistler, he placed the study of art and architecture at the heart of a moral assault on Victorian life. In the stone work of a Gothic cathedral, Ruskin saw all that was right about medieval society and all that was wrong about his own capitalist age.But why was Ruskin so critical of his own time? What deep currents of thought infused his ideas? And how much does our thinking, about society, the environment, art and work owe to this unusual man?With Dinah Birch, Professor of English, Liverpool University; Keith Hanley, Professor of English Literature and Director of the Ruskin Programme, Lancaster University; Stefan Collini, Professor of Intellectual History and English Literature, University of Cambridge.

Melvyn Bragg and guests discuss the heavenly host of Angels. George Bernard Shaw made the observation that "in heaven an angel is nobody in particular", but there is nothing commonplace about this description of angels from the Bible's book of Ezekiel:"They had the likeness of a man. And every one had four faces, and every one had four wings. And their feet were straight feet; and the sole of their feet was like the sole of a calf's foot: and they sparkled like the colour of burnished brass.... As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle." With angels like that, it is easy to see why they have caused so much controversy over the centuries.What part have angels played in western religion? How did they get their halos and their wings? And what are they really: Gods or men?With Martin Palmer, theologian and Director of the International Consultancy on Religion, Education and Culture; Valery Rees, Renaissance Scholar at the School of Economic Science; John Haldane, Professor of Philosophy, University of St Andrews.

Melvyn Bragg and guests discuss 'dark energy'. Only 5% of our universe is composed of visible matter, stars, planets and people; something called 'dark matter' makes up about 25% and an enormous 70% of the universe is pervaded with the mysteriously named 'dark energy'. It is a recent discovery and may be only a conjecture, but it has been invoked to explain an abiding riddle of the cosmos: if the expansion of the universe is powered by the energy of the Big Bang, then why isn't the expansion slowing down over time as the initial energy runs down and the attractive force of gravity asserts itself? Scientists had predicted a Big Crunch as the logical opposite of the Big Bang, but far from retracting, the expansion of the universe is actually accelerating...it's running away with itself.How do we know that the universe is behaving like this and what's causing it? If dark energy is the culprit, then what is this elusive, though omnipresent entity?With Sir Martin Rees, Astronomer Royal and Professor of Cosmology and Astrophysics, Cambridge University; Carolin Crawford, Royal Society University Research Fellow at the Institute of Astronomy, University of Cambridge; Sir Roger Penrose, Emeritus Rouse Ball Professor of Maths at Oxford University.
