Melvyn Bragg and guests discuss the range, depth and style of Browne (1605-82) , a medical doctor whose curious mind drew him to explore and confess his own religious views, challenge myths and errors in science and consider how humans respond to the transience of life. His Religio Medici became famous throughout Europe and his openness about his religion, in that work, was noted as rare when others either kept quiet or professed orthodox views. His Pseudodoxia Epidemica challenged popular ideas, whether about the existence of mermaids or if Adam had a navel, and his Hydriotaphia or Urn Burial was a meditation on what matters to humans when handling the dead. In 1923, Virginia Woolf wrote, "Few people love the writings of Sir Thomas Browne, but those that do are the salt of the earth." He also contributed more words to the English language than almost anyone, such as electricity, indigenous, medical, ferocious, carnivorous ambidextrous and migrant.With Claire Preston Professor of Renaissance Literature at Queen Mary University of LondonJessica Wolfe Professor of English and Comparative Literature at the University of North Carolina at Chapel HillAndKevin Killeen Professor of English at the University of YorkProducer: Simon Tillotson

Melvyn Bragg and guests discuss the impact of Grant's presidency on Americans in the years after the Civil War in which he, with Lincoln, had led the Union Army to victory. His predecessor, Andrew Johnson, was prepared to let the Southern States decide for themselves which rights to allow freed slaves; Grant supported equal rights, and he used troops and Enforcement Acts to defeat the Ku klux Klan which was violently suppressing African Americans. In later years Grant was remembered mainly for the corruption scandals under his terms of office, and for his failure to support or protect Native Americans, but in more recent decades his support for reconstruction has prompted a reassessement.WithErik Mathisen Lecturer in US History at the University of KentSusan-Mary Grant Professor of American History at Newcastle UniversityandRobert Cook Professor of American History at the University of SussexProducer: Simon Tillotson

Melvyn Bragg and guests discuss how scientists sought to understand the properties of gases and the relationship between pressure and volume, and what that search unlocked. Newton theorised that there were static particles in gases that pushed against each other all the harder when volume decreased, hence the increase in pressure. Those who argued that molecules moved, and hit each other, were discredited until James Maxwell and Ludwig Boltzmann used statistics to support this kinetic theory. Ideas about atoms developed in tandem with this, and it came as a surprise to scientists in C20th that the molecules underpinning the theory actually existed and were not simply thought experiments.
