In Our Time With Melvyn Bragg Folgen

Melvyn Bragg and guests discuss the study of earthquakes. A massive earthquake in 1755 devastated Lisbon, and this disaster helped inspire a new science of seismology which intensified after San Francisco in 1906 and advanced even further with the need to monitor nuclear tests around the world from 1945 onwards. While we now know so much more about what lies beneath the surface of the Earth, and how rocks move and crack, it remains impossible to predict when earthquakes will happen. Thanks to seismology, though, we have a clearer idea of where earthquakes will happen and how to make some of them less hazardous to lives and homes.WithRebecca Bell Senior lecturer in Geology and Geophysics at Imperial College LondonZoe Mildon Lecturer in Earth Sciences and Future Leaders Fellow at the University of PlymouthAnd James Hammond Reader in Geophysics at Birkbeck, University of LondonProducer: Simon Tillotson

Melvyn Bragg and guests discuss the ancient Sanskrit text the Arthashastra, regarded as one of the major works of Indian literature. Written in the style of a scientific treatise, it provides rulers with a guide on how to govern their territory and sets out what the structure, economic policy and foreign affairs of the ideal state should be. According to legend, it was written by Chanakya, a political advisor to the ruler Chandragupta Maurya (reigned 321 – 297 BC) who founded the Mauryan Empire, the first great Empire in the Indian subcontinent. As the Arthashastra asserts that a ruler should pursue his goals ruthlessly by whatever means is required, it has been compared with the 16th-century work The Prince by Machiavelli. Today, it is widely viewed as presenting a sophisticated and refined analysis of the nature, dynamics and challenges of rulership, and scholars value it partly because it undermines colonial stereotypes of what early South Asian society was like.

Melvyn Bragg and guests discuss the Russian prince who became a leading anarchist and famous scientist. Kropotkin (1842 - 1921) was born into privilege, very much in the highest circle of Russian society as a pageboy for the Tsar, before he became a republican in childhood and dropped the title 'Prince'. While working in Siberia, he started reading about anarchism and that radicalised him further, as did his observations of Siberian villagers supporting each other without (or despite) a role for the State. He made a name for himself as a geographer but soon his politics landed him in jail in St Petersburg, from which he escaped to exile in England where he was fêted, with growing fame leading to lecture tours in the USA. His time in Siberia also inspired his ideas on the importance of mutual aid in evolution, a counter to the dominant idea from Darwin and Huxley that life was a gladiatorial combat in which only the fittest survived. Kropotkin became such a towering figure in public life that, returning to Russia, he was able to challenge Lenin without reprisal, and Lenin in turn permitted his enormous public funeral there, attended by 20,000 mourners.With Ruth Kinna Professor of Political Theory at Loughborough UniversityLee Dugatkin Professor of Biology at the University of LouisvilleAndSimon Dixon The Sir Bernard Pares Professor of Russian History at University College London
