In Our Time With Melvyn Bragg Folgen

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.

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.

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.
