Melvyn Bragg and his guests discuss the history of crystallography, the study of crystals and their structure. The discovery in the early 20th century that X-rays could be diffracted by a crystal revolutionised our knowledge of materials. This crystal technology has touched most people's lives, thanks to the vital role it plays in diverse scientific disciplines - from physics and chemistry, to molecular biology and mineralogy. To date, 28 Nobel Prizes have been awarded to scientists working with X-ray crystallography, an indication of its crucial importance. The history of crystallography began with the work of Johannes Kepler in the 17th century, but perhaps the most crucial leap in understanding came with the work of the father-and-son team the Braggs in 1912. They built on the work of the German physicist Max von Laue who had proved that X-rays are a form of light waves and that it was possible to scatter these rays using a crystal. The Braggs undertook seminal experiments which transformed our perception of crystals and their atomic arrangements, and led to some of the most significant scientific findings of the last century - such as revealing the structure of DNA.

Melvyn Bragg and his guests discuss the Borgias, the most notorious family in Renaissance Italy. Famed for their treachery and corruption, the Borgias produced two popes during their time of dominance in Rome in the late 15th century. The most well-known of these two popes is Alexander VI, previously Cardinal Rodrigo Borgia. He was accused of buying votes to elect him to the papacy and openly promoted his children in positions of power. Rodrigo's daughter, Lucrezia, is widely remembered as a ruthless poisoner; his son, Cesare, as a brutal soldier. Murder, intrigue and power politics characterised their rule, but many of the stories now told about their depraved behaviour and evil ways emerged after their demise and gave rise to the so-called 'Black Legend'. The sullied reputation of the Borgia dynasty endures even today and their lives have provided a major theme for plays, novels and over forty films.With:Evelyn Welch Professor of Renaissance Studies at Queen Mary, University of LondonCatherine Fletcher Lecturer in Public History at the University of SheffieldChristine Shaw Honorary Research Fellow at Swansea University Producer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the French philosopher and social activist Simone Weil. Born in Paris in 1909 into a wealthy, agnostic Jewish family, Weil was a precocious child and attended the prestigious Ecole Normale Superieure in Paris, achieving the top marks in her class (Simone de Beauvoir came second). Weil rejected her comfortable background and chose to work in fields and factories to experience the life of the working classes at first hand. She was acutely sensitive to human suffering and devoted her life to helping those less fortunate than herself. Despite her belief in pacifism she volunteered on the Republican side during the Spanish Civil War and later joined the French Resistance movement in England. Her philosophy was both complex and intense. She argued that the presence of evil and suffering in the world was evidence of God's love and that Man has no right to ask anything of God or of anyone whom they love. Love which expects reward was not love at all in Weil's eyes. Weil died of TB in Kent at the age of only 34. Her strict lifestyle and self-denial may have contributed to her early death. T.S Eliot said "she was not just a woman of genius, but was a genius akin to that of a saint"; Albert Camus believed she was "the only great spirit of our time."

Melvyn Bragg and his guests discuss the Upanishads, the ancient sacred texts of Hinduism. Dating from about 700 BC, the Upanishads were passed down through an oral tradition in priestly castes and were not written down until the 6th century AD. They constitute the final part of the Vedas, the collection of texts which form the foundation of the Indian Hindu world, and were originally spoken during sacrificial rituals.Yet the Upanishads go beyond incantations performed during sacrifices, and ask profound questions about human existence and man's place in the cosmos. The concepts of Brahman (the universal cosmic power) and Atman (the deeper soul of the individual) are central to the understanding of the Upanishads. Each individual treatise has its own character. Some are poetic; some are scientific; others are dialogues between kings and sages or metaphysical reflections. More than one hundred Upanishads were produced, thirteen of which are regarded as the canonical scriptures of Hinduism.With:Jessica Frazier Lecturer in Religious Studies at the University of Kent and a Research Fellow at the Oxford Centre for Hindu Studies at the University of OxfordChakravarthi Ram-Prasad Professor of Comparative Religion and Philosophy at Lancaster UniversitySimon Brodbeck Lecturer in Religious Studies at the University of CardiffProducer: Natalia Fernandez.

Melvyn Bragg and his guests discuss The Anarchy, the civil war that took place in mid-twelfth century England. The war began as a succession dispute between the Empress Matilda, daughter of Henry I, and her cousin, Stephen of Blois. On Henry's death Stephen seized the English throne and held it for a number of years before Matilda wrestled it from him, although she was chased out of London before she could be crowned. The Anarchy dragged on for nearly twenty years and is so called because of the chaos and lawlessness that characterised the period. Yet only one major battle ever took place, the Battle of Lincoln in 1141, and any other fighting associated with the conflict was fairly localised. This has led historians to question the accuracy of labelling the civil war as The Anarchy, a name only bestowed on the era in the 19th century. But why did Matilda fail to become the monarch, and what impact did it have on the way England was ruled in centuries to come?With: John Gillingham Emeritus Professor of History at the London School of Economics and Political ScienceLouise Wilkinson Reader in Medieval History at Canterbury Christ Church UniversityDavid Carpenter Professor of Medieval History at Kings College London.

Melvyn Bragg and his guests discuss Fermat's Last Theorem. In 1637 the French mathematician Pierre de Fermat scribbled a note in the margin of one of his books. He claimed to have proved a remarkable property of numbers, but gave no clue as to how he'd gone about it. "I have found a wonderful demonstration of this proposition," he wrote, "which this margin is too narrow to contain". Fermat's theorem became one of the most iconic problems in mathematics and for centuries mathematicians struggled in vain to work out what his proof had been. In the 19th century the French Academy of Sciences twice offered prize money and a gold medal to the person who could discover Fermat's proof; but it was not until 1995 that the puzzle was finally solved by the British mathematician Andrew Wiles.

Melvyn Bragg and his guests discuss the life and influence of William Caxton, the merchant who brought the printing press to the British Isles. After spending several years working as a printer in Bruges, Caxton returned to London and in 1476 set up his first printing press in Westminster, and also imported and sold other printed books. Caxton concentrated on producing popular books that he knew would sell, such as Chaucer's 'Canterbury Tales' and small liturgical 'books of hours'. The standard of Caxton's printing may have lagged behind that on the continent, but he was a skilful businessman and unusually for printers at the time, he managed not to go bankrupt. The advent of print is now seen as one of the great revolutions in intellectual history - although many scholars believe it was a revolution that took many generations to have an effect.With:Richard Gameson Professor of the History of the Book at the University of DurhamJulia Boffey Professor of Medieval Studies in the English Department at Queen Mary, University of LondonDavid Rundle Member of the History Faculty at the University of OxfordProducer: Natalia Fernandez.

Melvyn Bragg and his guests discuss the life and achievements of Hannibal. One of the most celebrated military leaders in history, Hannibal was the Carthaginian general who led an entire army, complete with elephants, across the Alps in order to attack the Roman Republic. He lived at a time of prolonged hostility between the two great Mediterranean powers, Rome and Carthage, and was the Carthaginians' inspirational leader during the Second Punic War which unfolded between 218 and 202 BC. His career ended in defeat and exile, but he achieved such fame that even his enemies the Romans erected statues of him. Centuries later his tactical genius was admired and studied by generals including Napoleon and Wellington.With:Ellen O'Gorman Senior Lecturer in Classics at the University of BristolMark Woolmer Senior Tutor in the Department of Classics and Ancient History at the University of DurhamLouis Rawlings Senior Lecturer in Ancient History at Cardiff University.Producer: Natalia Fernandez.
