Melvyn Bragg and guests discuss the pioneering Danish astronomer Tycho Brahe (1546 – 1601) whose charts offered an unprecedented level of accuracy.

In 1572 Brahe's observations of a new star challenged the idea, inherited from Aristotle, that the heavens were unchanging. He went on to create his own observatory complex on the Danish island of Hven, and there, working before the invention of the telescope, he developed innovative instruments and gathered a team of assistants, taking a highly systematic approach to observation. A second, smaller source of renown was his metal prosthetic nose, which he needed after a serious injury sustained in a duel.

Melvyn Bragg and guests discuss the discovery made in 1911 by the Dutch physicist Heike Kamerlingh Onnes (1853-1926). He came to call it Superconductivity and it is a set of physical properties that nobody predicted and that none, since, have fully explained. When he lowered the temperature of mercury close to absolute zero and ran an electrical current through it, Kamerlingh Onnes found not that it had low resistance but that it had no resistance. Later, in addition, it was noticed that a superconductor expels its magnetic field. In the century or more that has followed, superconductors have already been used to make MRI scanners and to speed particles through the Large Hadron Collider and they may perhaps bring nuclear fusion a little closer (a step that could be world changing).

The image above is from a photograph taken by Stephen Blundell of a piece of superconductor levitating above a magnet.

Melvyn Bragg and guests discuss A Theory of Justice by John Rawls (1921 - 2002) which has been called the most influential book in twentieth century political philosophy. It was first published in 1971. Rawls (pictured above) drew on his own experience in WW2 and saw the chance in its aftermath to build a new society, one founded on personal liberty and fair equality of opportunity. While in that just society there could be inequalities, Rawls’ radical idea was that those inequalities must be to the greatest advantage not to the richest but to the worst off.

Melvyn Bragg and guests discuss Donne (1573-1631), known now as one of England’s finest poets of love and notable in his own time as an astonishing preacher. He was born a Catholic in a Protestant country and, when he married Anne More without her father's knowledge, Donne lost his job in the government circle and fell into a poverty that only ended once he became a priest in the Church of England. As Dean of St Paul’s Cathedral, his sermons were celebrated, perhaps none more than his final one in 1631 when he was plainly in his dying days, as if preaching at his own funeral.

Melvyn Bragg and guests discuss the stench from the River Thames in the hot summer of 1858 and how it appalled and terrified Londoners living and working beside it, including those in the new Houses of Parliament which were still under construction. There had been an outbreak of cholera a few years before in which tens of thousands had died, and a popular theory held that foul smells were linked to diseases. The source of the problem was that London's sewage, once carted off to fertilise fields had recently, thanks to the modern flushing systems, started to flow into the river and, thanks to the ebb and flow of the tides, was staying there and warming in the summer sun. The engineer Joseph Bazalgette was given the task to build huge new sewers to intercept the waste, a vast network, so changing the look of London and helping ensure there were no further cholera outbreaks from contaminated water.

Melvyn Bragg and guests discuss Jane Austen’s last complete novel, which was published just before Christmas in 1817, five months after her death. It is the story of Anne Elliot, now 27 and (so we are told), losing her bloom, and of her feelings for Captain Wentworth who she was engaged to, 8 years before – an engagement she broke off under pressure from her father and godmother. When Wentworth, by chance, comes back into Anne Elliot's life, he is still angry with her and neither she nor Austen's readers can know whether it is now too late for their thwarted love to have a second chance.

Melvyn Bragg and guests discuss Orson Welles' film, released in 1941, which is widely acclaimed as one of the greatest, if not the greatest, films yet made. Welles plays the lead role of Charles Foster Kane, a newspaper magnate, and Welles directed, produced and co-wrote this story of loneliness at the heart of a megalomaniac. The plot was partly inspired by the life of William Randolph Hearst, who then used the power of his own newspapers to try to suppress the film’s release. It was to take some years before Citizen Kane reached a fuller audience and, from that point, become so celebrated.

Melvyn Bragg and guests discuss the momentum behind rebellion in Ireland in 1798, the people behind the rebellion and the impact over the next few years and after. Amid wider unrest, the United Irishmen set the rebellion on its way, inspired by the French and American revolutionaries and their pursuit of liberty. When it broke out in May the United Irishmen had an estimated two hundred thousand members, Catholic and Protestant, and the prospect of a French invasion fleet to back them. Crucially for the prospects of success, some of those members were British spies who exposed the plans and the military were largely ready - though not in Wexford where the scale of rebellion was much greater. The fighting was initially fierce and brutal and marked with sectarianism but had largely been suppressed by the time the French arrived in August to declare a short-lived republic. The consequences of the rebellion were to be far reaching, not least in the passing of Acts of Union in 1800.

Melvyn Bragg and guests discuss The Song of the Nibelungs, a twelfth century German epic, full of blood, violence, fantasy and bleakness. It is a foundational work of medieval literature, drawing on the myths of Scandinavia and central Europe. The poem tells of two couples, Siegfried and Kriemhild and Gunther and Brunhilda, whose lives are destroyed by lies and revenge. It was extremely popular in its time, sometimes rewritten with happier endings, and was rediscovered by German Romantics and has since been drawn from selectively by Wagner, Fritz Lang and, infamously, the Nazis looking to support ideas on German heritage.

The image above is of Siegfried seeing Kriemhild for the first time, a miniature from the Hundeshagenschen Code manuscript dating from 15th Century.

Melvyn Bragg and guests discuss the voyage of HMS Challenger which set out from Portsmouth in 1872 with a mission a to explore the ocean depths around the world and search for new life. The scale of the enterprise was breath taking and, for its ambition, it has since been compared to the Apollo missions. The team onboard found thousands of new species, proved there was life on the deepest seabeds and plumbed the Mariana Trench five miles below the surface. Thanks to telegraphy and mailboats, its vast discoveries were shared around the world even while Challenger was at sea, and they are still being studied today, offering insights into the ever-changing oceans that cover so much of the globe and into the health of our planet.
