In Our Time Folgen

After 27 years, Melvyn Bragg has decided to step down from the In Our Time presenter’s chair. With over a thousand episodes to choose from, he has selected just six that capture the huge range and depth of the subjects he and his experts have tackled. In this fifth of his choices, we hear Melvyn Bragg and his guests discuss a key figure from quantum mechanics.Their topic is the life and ideas of Wolfgang Pauli (1900-1958), whose Exclusion Principle is one of the key ideas in quantum mechanics. A brilliant physicist, at 21 Pauli wrote a review of Einstein's theory of general relativity and that review is still a standard work of reference today. The Pauli Exclusion Principle proposes that no two electrons in an atom can be at the same time in the same state or configuration, and it helps explain a wide range of phenomena such as the electron shell structure of atoms. Pauli went on to postulate the existence of the neutrino, which was confirmed in his lifetime. Following further development of his exclusion principle, Pauli was awarded the Nobel Prize in Physics in 1945 for his 'decisive contribution through his discovery of a new law of Nature'. He also had a long correspondence with Jung, and a reputation for accidentally breaking experimental equipment which was dubbed The Pauli Effect.With Frank Close Fellow Emeritus at Exeter College, University of OxfordMichela Massimi Professor of Philosophy of Science at the University of EdinburghandGraham Farmelo Bye-Fellow of Churchill College, University of CambridgeProducer: Simon TillotsonSpanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Melvyn Bragg and expert guests explore the characters, events and discoveries that have shaped our world

Melvyn Bragg and guests discuss Katsushika Hokusai (1760-1849), the Japanese artist whose views of Mt Fuji such as The Great Wave off Kanagawa (pictured) are some of the most iconic in world art. He worked as Japan was slowly moving towards greater contact with the outside world, trading with China and allowing two Dutch ships to dock each year. From these ships he picked up new synthetic colours and illustrations with Western compositions, which he incorporated in his traditional wood block prints. The quality of his images helped drive demand for prints among the highly literate Japanese public, particularly those required to travel to Edo under feudal obligations and who wanted to collect all his prints. As well as the quality of his work, Hokusai's success stems partly from his long life and career. He completed some of his most memorable works in his 70s and 80s and claimed he would not reach his best until he was 110.With Angus Lockyer Lecturer in Japanese History at SOAS University of LondonRosina Buckland Senior Curator of Japanese Collections at the National Museum of ScotlandAnd Ellis Tinios Honorary Lecturer in the School of History, University of LeedsProducer: Simon Tillotson.

Melvyn Bragg and guests discuss what is often called one of the most significant battles in history. In 480BC in the Saronic Gulf near Athens, between the mainland and the island of Salamis, a fleet of Greek allies decisively defeated a larger Persian-led fleet. This halted the further Persian conquest of Greece and, at Plataea and Mycale the next year, further Greek victories brought Persian withdrawal and the immediate threat of conquest to an end. To the Greeks, this enabled a flourishing of a culture that went on to influence the development of civilisation in Rome and, later, Europe and beyond. To the Persians, it was a reverse at the fringes of their vast empire but not a threat to their existence, as it was for the Greek states, and attention turned to quelling unrest elsewhere.With Lloyd Llewellyn-Jones Professor in Ancient History at Cardiff UniversityLindsay Allen Lecturer in Greek and Near Eastern History, King's College LondonandPaul Cartledge Emeritus Professor of Greek Culture and AG Leventis Senior Research Fellow at Clare College, University of CambridgeProducer: Simon Tillotson.
