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.

Academic David Bradshaw, psychologist Daniel Pick, and scholar Michele Barrett discuss Aldous Huxley's 'Brave New World' in this podcast. They explore Huxley's dystopian vision, societal conformity, Americanization, influence of eugenics and Ford, Huxley's response to societal turmoil, the savage's revelation, and themes of orchestration and ethical dilemmas in the novel.

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.

Melvyn Bragg and guests discuss The School of Athens – the fresco painted by the Italian Renaissance painter, Raphael, for Pope Julius II’s private library in the Vatican. The fresco depicts some of the most famous philosophers of ancient times, including Aristotle and Plato, engaged in discussion amidst the splendour of a classical Renaissance chamber. It is considered to be one of the greatest images in Western art not only because of Raphael’s skill as a painter, but also his ability to have created an enduring image that continues to inspire philosophical debate today. Raphael captured something essential about the philosophies of these two men, but he also revealed much about his own time. That such a pagan pair could be found beside a Pope in private tells of the complexity of intellectual life at the time when classical learning was reborn in what we now call the Renaissance.With Angie Hobbs, Associate Professor in Philosophy at the University of Warwick; Valery Rees, Renaissance scholar and senior member of the Language Department at the School of Economic Science; Jill Kraye, Professor of the History of Renaissance Philosophy and Librarian at the Warburg Institute at the University of London

In the hot summer of 1900, Peking, the capital of China, was under heavy siege. But the surrounding forces were not foreign, they were Chinese. This was the Boxer Rebellion, the moment when the 'Society of Righteous and Harmonious Fists', known as the boxers, purged China of foreign merchants and missionaries. The Boxers had came out of the northern provinces, they claimed their fists were stronger than fire and they were invincible to bullets. But they were also desperate and starving and they blamed foreigners for their plight. In the end, the Boxer rebellion failed but it changed China and, more than a hundred years later, the spirit of the Boxer Rebellion lives on. They may have lost their battles but they may have won their war.

Melvyn Bragg and guests discuss the Library at Alexandria. Founded by King Ptolemy in the 3rd century BC the library was the first attempt to collect all the knowledge of the ancient world in one place. Scholars including Archimedes and Euclid came to study its grand array of papyri. the legacy of the library is with us today, not just in the ideas it stored and the ideas it seeded but also in the way it organised knowledge and the tools developed for dealing with it. It still influences the things we know and the way we know them to this day.With Simon Goldhill, Professor of Greek at the University of Cambridge; Matthew Nicholls, Lecturer in Classics at the University of Reading; Serafina Cuomo, Reader in Roman History at Birkbeck College, University of London.

Melvyn Bragg and guests discuss one of the deepest problems in contemporary physics. It’s called the measurement problem and it emerged from the flurry of activity in the early 20th century that gave rise to Quantum Mechanics. If the most famous fruit in physics is an apple, the most famous animal in physics is a cat. Schrödinger’s cat is named after Edwin Schrödinger, a theoretical physicist who in the early 20th century helped to develop the radical theories of Quantum Mechanics. The cat does not actually exist – it is the subject of a thought experiment – in which the rules of quantum mechanics make it appear both dead and alive at the same time.The problem of a cat that is both dead and alive illustrates the challenges of quantum physics and at the heart of this apparent absurdity is a thing called the measurement problem.The measurement problem arises because we don’t really understand how the atoms that constitute our world behave. They are fundamentally mysterious to us, even shocking, and they defy our attempts to measure and make sense of them. Possible solutions range from the existence of multiple realities to the rather more mundane possibility of an error in our mathematics - but a solution, if found, could transform our understanding of reality.

Melvyn Bragg and guests, including Steve Connor and Lawrence Rainey, discuss TS Eliot's seminal poem The Waste Land and its ambivalence to the modern world of technology, democracy and capitalism that was being forged around it.

Melvyn Bragg and guests discuss the Observatory in Jaipur with its vast and beautiful instruments built to make astronomical measurements of the stars. Commissioned in the early 18th century by the Rajput prince and child prodigy, Jai Singh, it was at the centre of attempts to marry hundreds of years of Indian and Persian astronomical tradition. The Observatory was also at the very centre of the city which was laid out according to astrological principles. Jai Singh’s observatory was the cutting edge of Indian astronomy but also a repository for aeons of Hindu and Islamic intellectual life. The instruments were extraordinarily accurate for the time but used no lenses and were built of masonry, not metal. They helped to develop astrological tables, immensely important in Hindu Society, and come down to us as a record of Indian astronomy on the cusp of colonialism.
