Melvyn Bragg and guests Steve Jones, Bill Amos and Eleanor Weston discuss the evolutionary history of the whale. The ancestor of all whales alive today was a small, land-based mammal with cloven hoofs, perhaps like a pig or a big mole. How this creature developed into the celebrated leviathan of the deep is one of the more extraordinary stories in the canon of evolution. The whale has undergone vast changes in size, has moved from land to water, lost its legs and developed specialised features such as filter feeding and echo location. How it achieved this is an exemplar of how evolution works and how natural selection can impose extreme changes on the body shape and abilities of living things. How the story of the whales was pieced together also reveals the various forms of evidence - from fossils to molecules - that we now use to understand the ancestry of life on Earth.Steve Jones is Professor of Genetics at University College London; Eleanor Weston is a mammalian palaeontologist at the Natural History Museum, London; Bill Amos is Professor of Evolutionary Genetics at Cambridge University.

Melvyn Bragg and guests Andrew Wheatcroft, Claire Norton and Jeremy Black discuss the Ottoman siege of Vienna in 1683, when the Ottoman Empire tried to capture the capital city of the Hapsburg monarchs. The ensuing tale of blood and drama helped define the boundaries of Europe. In June 1683, a man called Kara Mustafa made a journey to Vienna. That a Muslim Turk should come to a Catholic city was not unusual, but Kara Mustafa did so at the head of the Ottoman Army. Vienna was the capital of the Hapsburg Empire and he intended to take it. The ensuing siege has been held responsible for many things, from the invention of the croissant to the creation of Viennese coffee. But most importantly, it has come to be seen as a clash of civilisations, one that helped to define a series of boundaries, between Europe and Asia, Christian and Muslim, Hapsburg and Ottoman, that influence the view between Vienna and Istanbul to this day. But to see the siege as a defining moment in east/west relations may be to read back into history an idea that was not true at the time.Claire Norton is Lecturer in History at St Mary's University College, London; Andrew Wheatcroft is Professor of International Publishing at Stirling University; Jeremy Black is Professor of History at the University of Exeter.

Melvyn Bragg and guests Nicholas Vincent, David Carpenter and Michael Clanchy discuss the Magna Carta, the oft-proclaimed foundation of English liberties.The Magna Carta has been cited ever since its issue in 1215 as a foundation stone of English liberties. It includes clauses of universal justice, some of which are still on the statute book, but also sorted out the fishing rights in the upper Thames. Whether Magna Carta is a genuine proclamation of universal liberty or a hotchpotch of baronial self-interest has been debated ever since. Melvyn and his guests examine the ideas contained within it, assess their legacy and find out what really happened all those years ago in a tent in Runnymede.

Melvyn Bragg and guests Frank Close, Jocelyn Bell Burnell and Ruth Gregory discuss the Vacuum of Space. The idea that there is a nothingness at the heart of nature has exercised philosophers and scientists for millennia, from Thales's belief that all matter was water to Newton's concept of the Ether and Einstein's idea of Space-Time. Recently, physicists have realised that the vacuum is not as empty as we thought and that the various vacuums of nature vibrate with forces and energies, waves and particles and the mysterious phenomena of the Higgs field and dark energy.

Melvyn Bragg and guests discuss the building of St Petersburg, Peter the Great's showcase city for a modern, European Russia. It is a city of ideas. of progress and the Baroque, of Russian identity and Tsarist power. The building of St Petersburg is a testament to Tsarist power but it is also a city of ideas; of progress, of the Baroque and Russian identity. Beset by fire and flood, the city was founded by Peter the Great in 1703 to symbolise a new Russia, one that faced away from the Slavic East and towards the European West. To this end Peter and his heirs imported European architects, craftsmen and merchants to fashion his new capital.The result is a grandiose European city set amidst the freezing swamps of the Baltic coast; a Venice or Rome of the North. Indeed, the Venetian art connoisseur, Francesco Algarotti called St Petersburg ‘a window through which Russia looks on Europe’. It is a city of beauty built upon the cruelty of a tyrant and to this day encapsulates many of the contradictions of Russia.With Simon Dixon, Sir Bernard Pares Professor of Russian History at University College London; Janet Hartley, Professor of International History at the London School of Economics; Anthony Cross, Emeritus Professor of Slavonic Studies at the University of Cambridge

Melvyn Bragg and guests Krista Cowman, June Purvis and Julia Bush discuss suffragism, a name for the various movements to get the vote for women in the 19th and early-20th century. On the 4th June 1913 the Epsom Derby was underway. King George V was there watching his horse Anmer, ridden by Herbert Jones. Also watching was a young woman called Emily Davison. As the horses thundered towards the finish line, Emily Davison stepped through the barrier and threw herself in front of the King's horse and died of her injuries four days later. Davison was a suffragette, a campaigner for the woman's right to vote and her death is perhaps the most powerful image of that entire movement. Emmeline Pankhurst and her Suffragettes are famous for their militant campaign of suicide, violence and direct action, but Suffragism was a broader movement involving letter writing, reasoned argument, journalism and parliamentary petition - all played out across biology, medicine, law, psychology, politics and the military amidst the rising tide of democratic ideas.

Melvyn Bragg and guests David Bradshaw, Daniel Pick and Michele Barrett discuss Aldous Huxley's dystopian 1932 novel, Brave New World. In Act V Scene I of Shakespeare's The Tempest, the character Miranda declares 'O wonder! How many Godly creatures are there here! How beauteous mankind is! O Brave new world! That has such people in it!'. It is perhaps the only line of Shakespeare to be made famous by someone else, for Brave New World is not associated with Prospero's Island of sprites, magic and wondrous noises, but with Aldous Huxley's dystopia of eugenics, soma and zero gravity tennis. A world, incidentally, upon which literary references to Shakespeare would be entirely lost. Brave New World is a lurid, satirical dystopia in which the hopes and fears of the 1930s are writ large and yet the book seems uncannily prescient about our own time. But why did Huxley feel the need to write it and is Brave New World really as dystopian as we are led to believe?

Patricia Fara, Stephen Pumfrey and Rhodri Lewis join Melvyn Bragg to discuss the Jacobean lawyer, political fixer and alleged founder of modern science Francis Bacon.In the introduction to Thomas Spratt's History of the Royal Society, there is a poem about man called Francis Bacon which declares 'Bacon, like Moses, led us forth at last, The barren wilderness he past, Did on the very border stand Of the blest promis'd land, And from the mountain's top of his exalted wit, Saw it himself, and shew'd us it'.Francis Bacon was a lawyer and political schemer who climbed the greasy pole of Jacobean politics and then fell down it again. But he is most famous for developing an idea of how science should be done - a method that he hoped would slough off the husk of ancient thinking and usher in a new age. It is called Baconian Method and it has influenced and inspired scientists from Bacon's own time to the present day.
