Melvyn Bragg and guests discuss the assassination of Tsar Alexander II. On 1st March 1881, the Russian Tsar, Alexander II, was travelling through the snow to the Winter Palace in St Petersburg. An armed Cossack sat with the coach driver, another six Cossacks followed on horseback and behind them came a group of police officers in sledges. It was the day that the Tsar, known for his liberal reforms, had signed a document granting the first ever constitution to the Russian people.But his journey was being watched by a group of radicals called 'Narodnaya Volya' or 'The People's Will'. On a street corner near the Catherine Canal, they hurled the first of their bombs to halt the Tsar's iron-clad coach. When Alexander ignored advice and ventured out onto the snow to comfort his dying Cossacks, he was killed by another bomber who took his own life in the blast.Why did they kill the reforming Tsar? What was the political climate that inspired such extreme acts? And could this have been the moment that the Russian state started an inexorable march towards revolution?With Orlando Figes, Professor of History at Birkbeck College, University of London; Dominic Lieven, Professor of Russian Government, London School of Economics; Catriona Kelly, Professor of Russian, Oxford University.

Exploring the myth of Faust, his pact with the devil, and the different interpretations of his character throughout literature. Discussing the evolution of Faust from Marlowe to Goethe, the symbolism of the Faustian pact, and the representation of Faustus in modern literature by writers like Thomas Mann.

Melvyn Bragg and guests discuss the Second Law of Thermodynamics which can be very simply stated like this: "Energy spontaneously tends to flow from being concentrated in one place to becoming diffused and spread out". It was first formulated – derived from ideas first put forward by Lord Kelvin - to explain how a steam engine worked, it can explain why a cup of tea goes cold if you don't drink it and how a pan of water can be heated to boil an egg.But its application has been found to be rather grander than this. The Second Law is now used to explain the big bang, the expansion of the cosmos and even suggests our inexorable passage through time towards the 'heat death' of the universe. It's been called the most fundamental law in all of science, and CP Snow in his Two Cultures wrote: "Not knowing the Second Law of Thermodynamics is like never having read a work of Shakespeare".What is the Second Law? What are its implications for time and energy in the universe, and does it tend to be refuted by the existence of life and the theory of evolution?With John Gribbin, Visiting Fellow in Astronomy at the University of Sussex; Peter Atkins, Professor of Chemistry at Oxford University; Monica Grady, Head of Petrology and Meteoritics at the Natural History Museum.

Melvyn Bragg and guests discuss the extraordinary mind of the psychiatrist Carl Gustav Jung. In 1907 Sigmund Freud met a young man and fell into a conversation that is reputed to have lasted for 13 hours. That man was the Swiss psychiatrist Carl Gustav Jung. Freud is celebrated as the great pioneer of the 20th century mind, but the idea that personality types can be 'introverted' or 'extroverted', that certain archetypal images and stories repeat themselves constantly across the collective history of mankind, and that personal individuation is the goal of life, all belong to Jung: "Your vision will become clear only when you look into your heart... Who looks outside, dreams. Who looks inside, awakens", he declared. And he also said "Show me a sane man and I will cure him for you".Who was Jung? What is the essence and influence of his thought? And how did he become such a controversial and, for many, such a beguiling figure?With Brett Kahr, Senior Clinical Research Fellow in Psychotherapy and Mental Health at the Centre for Child Mental Health in London and a practising Freudian; Ronald Hayman, writer and biographer of Jung; Andrew Samuels, Professor of Analytical Psychology at the University of Essex and a Jungian analyst in clinical practice.

Melvyn Bragg and guests discusses Zoroastrianism. "Now have I seen him with my own eyes, knowing him in truth to be the wise Lord of the good mind and of good deeds and words." Thus spake the real Zarathustra, the prophet and founder of the ancient and modern religion of Zoroastrianism. It has claims to be the world's first monotheistic creed and perhaps as long ago as 1200 BC Zarathustra also said, "I point out the way, it is the truth, it is for all living". Truth is a central tenet of the religion which holds that people must above all do good things, hear good things and see good things.How was the religion established in Ancient Persia, what is its body of beliefs and how have they been developed and disseminated?With Vesta Sarkhosh Curtis, Curator of Ancient Iranian Coins in the Department of Coins and Medals at the British Museum; Farrokh Vajifdar, Fellow of the Royal Asiatic Society; Alan Williams, Senior Lecturer in Comparative Religion at the University of Manchester.
