Oceanography

Melvyn Bragg and guests discuss the science of Oceanography. In 1870 Jules Verne described the deep ocean in 2,000 Leagues Under the Sea. He wrote: “The sea is an immense desert where man is never alone for he feels life, quivering around him on every side.” This was actually closer to the truth than the science of the time, when ‘Azoic Theory’ held sway and it was believed that nothing could exist below 600 metres. Now we estimate that there are more species in the deep ocean than in the rest of the planet put together, somewhere between 2 million and 100 million different species of organism are living on the ocean floor.Science has dispelled the idea that huge underground tunnels join our oceans together and the notion that giant Kraken lurk in the deep, but our seas still retain much of their mystery and there have been more men on the surface of the moon than at the bottom of the ocean. How should we understand the sea? With Margaret Deacon, visiting Research Fellow at Southampton Oceanography Centre and author of Scientists and the Sea, Tony Rice, Biological Oceanographer and author of Deep Ocean, Simon Schaffer, Reader in History and Philosophy of Science at the University of Cambridge, and a fellow of Darwin College.

The Ramayana

The Ramayana

Melvyn Bragg and guests discuss the Ramayana, the ancient Hindu epic which is regarded as one of the greatest works of world literature. Its importance in Indian culture has been compared to that of the Iliad and Odyssey in the West, and it’s still seen as a sacred text by Hindus today. Written in Sanskrit, it tells the story of the legendary prince and princess Rama and Sita, and the many challenges, misfortunes and choices that they face. About 24,000 verses long, the Ramayana is also one of the longest ancient epics. It’s a text that’s been hugely influential and it continues to be popular in India and elsewhere in Asia.

Megaliths

Megaliths

Melvyn Bragg and guests discuss megaliths - huge stones placed in the landscape, often visually striking and highly prominent. Such stone monuments in Britain and Ireland mostly date from the Neolithic period, and the most ancient are up to 6,000 years old. In recent decades, scientific advances have enabled archaeologists to learn a large amount about megalithic structures and the people who built them, but much about these stones remains unknown and mysterious. With Vicki Cummings Professor of Neolithic Archaeology at the University of Central LancashireJulian Thomas Professor of Archaeology at the University of Manchester and Susan Greaney Lecturer in Archaeology at the University of Exeter.

Paul Erdős

Paul Erdős

Paul Erdős (1913 – 1996) is one of the most celebrated mathematicians of the 20th century. During his long career, he made a number of impressive advances in our understanding of maths and developed whole new fields in the subject. He was born into a Jewish family in Hungary just before the outbreak of World War I, and his life was shaped by the rise of fascism in Europe, anti-Semitism and the Cold War. His reputation for mathematical problem solving is unrivalled and he was extraordinarily prolific. He produced more than 1,500 papers and collaborated with around 500 other academics. He also had an unconventional lifestyle. Instead of having a long-term post at one university, he spent much of his life travelling around visiting other mathematicians, often staying for just a few days. With Colva Roney-Dougal Professor of Pure Mathematics at the University of St AndrewsTimothy Gowers Professor of Mathematics at the College de France in Paris and Fellow of Trinity College, CambridgeandAndrew Treglown Associate Professor in Mathematics at the University of BirminghamThe image above shows a graph occurring in Ramsey Theory. It was created by Dr Katherine Staden, lecturer in the School of Mathematics at the Open University.

Stevie Smith

Stevie Smith

In 1957 Stevie Smith published a poetry collection called Not Waving But Drowning – and its title poem gave us a phrase which has entered the language. Its success has overshadowed her wider work as the author of more than half a dozen collections of poetry and three novels, mostly written while she worked as a secretary. Her poems, printed with her pen and ink sketches, can seem simple and comical, but often beneath the surface lurk themes of melancholy, loneliness, love and death. With Jeremy Noel-Tod Associate Professor in the School of Literature, Drama and Creative Writing at the University of East Anglia Noreen Masud Lecturer in Twentieth Century Literature at the University of Bristol and Will May Professor of Modern and Contemporary Literature at the University of SouthamptonThe photograph above shows Stevie Smith recording her story Sunday at Home, a finalist in the BBC Third Programme Short Story competition in 1949.

Chartism

Chartism

On 21 May 1838 an estimated 150,000 people assembled on Glasgow Green for a mass demonstration. There they witnessed the launch of the People’s Charter, a list of demands for political reform. The changes they called for included voting by secret ballot, equal-sized constituencies and, most importantly, that all men should have the vote. The Chartists, as they came to be known, were the first national mass working-class movement. In the decade that followed, they collected six million signatures for their Petitions to Parliament: all were rejected, but their campaign had a significant and lasting impact.

Tycho Brahe

Tycho Brahe

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. The image above shows Brahe aged 40, from the Atlas Major by Johann Blaeu.

Superconductivity

Superconductivity

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.With Nigel Hussey Professor of Experimental Condensed Matter Physics at the University of Bristol and Radbout UniversitySuchitra Sebastian Professor of Physics at the Cavendish Laboratory at the University of CambridgeAndStephen Blundell Professor of Physics at the University of Oxford and Fellow of Mansfield CollegeProducer: Simon Tillotson

Rawls' Theory of Justice

Rawls' Theory of Justice

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. WithFabienne Peter Professor of Philosophy at the University of WarwickMartin O’Neill Professor of Political Philosophy at the University of YorkAnd Jonathan Wolff The Alfred Landecker Professor of Values and Public Policy at the Blavatnik School of Government, University of Oxford and Fellow of Wolfson CollegeProducer: Simon Tillotson
