Melvyn Bragg and guests discuss what happens when parents from different species have offspring, despite their genetic differences. In some cases, such as the zebra/donkey hybrid in the image above, the offspring are usually infertile but in others the genetic change can lead to new species with evolutionary advantages. Hybrids can occur naturally, yet most arise from human manipulation and Darwin's study of plant and animal domestication informed his ideas on natural selection. With  Sandra Knapp

History

Society & Culture

Melvyn Bragg and guests discuss the last pagan ruler of the Roman Empire.  Fifty years after Constantine the Great converted to Christianity and introduced a policy of tolerating the faith across the empire, Julian (c.331 - 363 AD) aimed to promote paganism instead, branding Constantine the worst of all his predecessors.  Julian was a philosopher-emperor in the mould of Marcus Aurelius and was noted in his lifetime for his letters and his satires, and it was his surprising success as a general in his youth in Gaul that had propelled him to power barely twenty years after a rival had slaughtered his family.  Julian's pagan mission  and his life were brought to a sudden end while on campaign against the Sasanian Empire in the east, but he left so much written evidence of his ideas that he remains one of the most intriguing of all the Roman emperors and a hero to the humanists of the Enlightenment.

Julian the Apostate

Melvyn Bragg and guests discuss the dance which, from when it reached Britain in the early nineteenth century, revolutionised the relationship between music, literature and people here for the next hundred years.  While it may seem formal now, it was the informality and daring that drove its popularity, with couples holding each other as they spun round a room to new lighter music popularised by Johann Strauss, father and son, such as The Blue Danube.  Soon the Waltz expanded the creative world in poetry, ballet, novellas and music, from the Ballets Russes of Diaghilev to Moon River and Are You Lonesome Tonight. With Susan Jones

The Waltz

Melvyn Bragg and guests discuss the revolt that broke out in 1871 in Algeria against French rule, spreading over hundreds of miles and countless towns and villages before being brutally suppressed.  It began with the powerful Cheikh Mokrani and his family and was taken up by hundreds of thousands, becoming the last major revolt there before Algeria’s war of independence in 1954.  In the wake of its swift suppression though came further waves of French migrants to settle on newly confiscated lands, themselves displaced by French defeat in Europe and the loss of Alsace-Lorraine, and their arrival only increased tensions. The Mokrani Revolt came to be seen as a watershed between earlier Ottoman rule and full national identity, an inspiration to nationalists in the 1950s. With Natalya Benkhaled-Vince

The Mokrani Revolt

Melvyn Bragg and guests discuss the German physicist who, at the age of 23 and while still a student, effectively created quantum mechanics for which he later won the Nobel Prize.  Werner Heisenberg made this breakthrough in a paper in 1925 when, rather than starting with an idea of where atomic particles were at any one time, he worked backwards from what he observed of atoms and their particles and the light they emitted, doing away with the idea of their continuous orbit of the nucleus and replacing this with equations. This was momentous and from this flowed what’s known as his Uncertainty Principle, the idea that, for example, you can accurately measure the position of an atomic particle or its momentum, but not both.

Heisenberg's Uncertainty Principle

Melvyn Bragg and guests discuss the infamous assault of an army of the Holy Roman Emperor on the city of Rome in 1527. The troops soon broke through the walls of this holy city and, with their leader shot dead early on, they brought death and destruction to the city on an epic scale. Later writers compared it to the fall of Carthage or Jerusalem and soon the mass murder, torture, rape and looting were followed by disease which was worsened by starvation and opened graves.  It has been called the end of the High Renaissance, a conflict between north and south, between Lutherans and Catholics, and a fulfilment of prophecy of divine vengeance and, perhaps more persuasively, a consequence of military leaders not feeding or paying their soldiers other than by looting.
