The Evolution of Crocodiles

Melvyn Bragg and guests discuss The Battle of Lincoln on 20th May 1217, when two armies fought to keep, or to win, the English crown. This was a struggle between the Angevin and Capetian dynasties, one that followed Capetian successes over the Angevins in France. The forces of the new boy-king, Henry III, attacked those of Louis of France, the claimant backed by rebel Barons. Henry's regent, William Marshal, was almost seventy when he led the charge on Lincoln that day, and his victory confirmed his reputation as England's greatest knight. Louis sent to France for reinforcements but in August these, too, were defeated at sea, at the Battle of Sandwich. As part of the peace deal, Henry reissued Magna Carta, which King John had granted in 1215 but soon withdrawn, and Louis went home, leaving England's Anglo-French rulers more Anglo and less French than he had planned.

Melvyn Bragg and guests discuss the text and context of The Book of the Dead, also known as the Book of Coming Forth by Day, the ancient Egyptian collections of spells which were intended to help the recently deceased navigate the underworld. They flourished under the New Kingdom from C16th BC until the end of the Ptolemaic era in C1st BC, and drew on much earlier traditions from the walls of pyramids and on coffin cases. Almost 200 spells survive, though no one collection contains all of them, and one of the best known surrounds the weighing of the heart, the gods' final judgement of the deceased's life.With John Taylor Curator at the Department of Ancient Egypt and Sudan at the British MuseumKate Spence Senior Lecturer in Egyptian Archaeology at Cambridge University and Fellow of Emmanuel Collegeand Richard Parkinson Professor of Egyptology at the University of Oxford and Fellow of the Queen's CollegeProducer: Simon Tillotson.

The 13th-century English philosopher Roger Bacon is perhaps best known for his major work the Opus Maius. Commissioned by Pope Clement IV, this extensive text covered a multitude of topics from mathematics and optics to religion and moral philosophy. He is also regarded by some as an early pioneer of the modern scientific method. Bacon's erudition was so highly regarded that he came to be known as 'Doctor Mirabilis' or 'wonderful doctor'. However, he is a man shrouded in mystery. Little is known about much of his life and he became the subject of a number of strange legends, including one in which he allegedly constructed a mechanical brazen head that would predict the future.

Melvyn Bragg discusses the life and times of Rosa Luxemburg (1871-1919), 'Red Rosa', who was born in Poland under the Russian Empire and became one of the leading revolutionaries in an age of revolution. She was jailed for agitation and for her campaign against the Great War which, she argued, pitted workers against each other for the sake of capitalism. With Karl Liebknecht and other radicals, she founded the Spartacus League in the hope of ending the war through revolution. She founded the German Communist Party with Liebknecht; with the violence that followed the German Revolution of 1918, her opponents condemned her as Bloody Rosa. She and Liebknecht were seen as ringleaders in the Spartacus Revolt of 1919 and, on 15th January 1919, the Freikorps militia arrested and murdered them. While Luxemburg has faced opposition for her actions and ideas from many quarters, she went on to become an iconic figure in East Germany under the Cold War and a focal point for opposition to the Soviet-backed leadership.With Jacqueline Rose Co-Director of the Birkbeck Institute for the Humanities, Birkbeck, University of LondonMark Jones Irish Research Council fellow at the Centre for War Studies, University College Dublinand Nadine Rossol Senior lecturer in Modern European History at the University of EssexProducer: Simon Tillotson.

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.

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.

Melvyn Bragg and guests discuss the high temperatures that marked the end of the Paleocene and start of the Eocene periods, about 50m years ago. Over c1000 years, global temperatures rose more than 5 C on average and stayed that way for c100,000 years more, with the surface of seas in the Arctic being as warm as those in the subtropics. There were widespread extinctions, changes in ocean currents, and there was much less oxygen in the sea depths. The rise has been attributed to an increase of carbon dioxide and methane in the atmosphere, though it is not yet known conclusively what the source of those gases was. One theory is that a rise in carbon dioxide, perhaps from volcanoes, warmed up the globe enough for warm water to reach the bottom of the oceans and so release methane from frozen crystals in the sea bed. The higher the temperature rose and the longer the water was warm, the more methane was released. Scientists have been studying a range of sources from this long period, from ice samples to fossils, to try to understand more about possible causes.
