The Measurement Problem in Physics

Melvyn Bragg and guests discuss one of the deepest problems in contemporary physics. It’s called the measurement problem and it emerged from the flurry of activity in the early 20th century that gave rise to Quantum Mechanics. If the most famous fruit in physics is an apple, the most famous animal in physics is a cat. Schrödinger’s cat is named after Edwin Schrödinger, a theoretical physicist who in the early 20th century helped to develop the radical theories of Quantum Mechanics. The cat does not actually exist – it is the subject of a thought experiment – in which the rules of quantum mechanics make it appear both dead and alive at the same time.The problem of a cat that is both dead and alive illustrates the challenges of quantum physics and at the heart of this apparent absurdity is a thing called the measurement problem.The measurement problem arises because we don’t really understand how the atoms that constitute our world behave. They are fundamentally mysterious to us, even shocking, and they defy our attempts to measure and make sense of them. Possible solutions range from the existence of multiple realities to the rather more mundane possibility of an error in our mathematics - but a solution, if found, could transform our understanding of reality. With Basil Hiley, Emeritus Professor of Physics at Birkbeck, University of London, Simon Saunders, Reader in Philosophy of Physics and University Lecturer in Philosophy of Science at the University of Oxford; Roger Penrose, Emeritus Rouse Ball Professor of Mathematics at the University of Oxford

The Observatory at Jaipur

Melvyn Bragg and guests discuss the Observatory in Jaipur with its vast and beautiful instruments built to make astronomical measurements of the stars. Commissioned in the early 18th century by the Rajput prince and child prodigy, Jai Singh, it was at the centre of attempts to marry hundreds of years of Indian and Persian astronomical tradition. The Observatory was also at the very centre of the city which was laid out according to astrological principles. Jai Singh’s observatory was the cutting edge of Indian astronomy but also a repository for aeons of Hindu and Islamic intellectual life. The instruments were extraordinarily accurate for the time but used no lenses and were built of masonry, not metal. They helped to develop astrological tables, immensely important in Hindu Society, and come down to us as a record of Indian astronomy on the cusp of colonialism. With Chandrika Kaul, Lecturer in Modern History at the University of St Andrews; David Arnold, Professor of Asian and Global History at the University of Warwick; Chris Minkowski, Professor in Sanskrit at the University of Oxford

The Brothers Grimm

Melvyn Bragg discusses the fairy tales of the Brothers Grimm with Juliette Wood, Marina Warner and Tony Phelan. The German siblings who in 1812 published a collection of fairy tales including Rapunzel, Hansel and Gretel, Cinderella and Rumpelstiltskin. But the Grimm versions are surprisingly, sometimes shockingly, different. Cinderella has no fairy godmother, her ugly sisters are not ugly but they do have their eyes pecked out by pigeons. Sleeping Beauty does not have an evil stepmother, Rapunzel is pregnant and Frog Princes do not get kissed but thrown against walls. They may not be the fairy tales as we know them, but without the Brothers Grimm we might not know them at all. But why did two respectable German linguists go chasing after fairy stories, what do the stories tell us about German culture and romantic nationalism at the time and why do these ever-evolving tales of horror, wonder and fantasy continue to hold us in thrall?With Juliette Wood, Associate Lecturer in Folklore at Cardiff University; Marina Warner, Professor in the Department of Literature, Film and Theatre Studies at the University of Essex; Tony Phelan, Professor in German at Keble College, Oxford.
