Wonder at the natural world has inspired people and fuelled curiosity for millennia. The ancient Greek Theophrastus had interests that spread far and wide, from biology and physics to ethics and metaphysics. But although he was Aristotle’s friend and collaborator, and his notes on botany inspired Linnaeus, his name has mostly been forgotten. The writer Laura Beatty’s new book, Looking for Theophrastus, aims to rescue him from obscurity. The scientist, Suzie Sheehy, still feels a childlike wonder at the way physics seems to be able to describe everything – from the smallest subatomic particle to the scale of the Universe. In The Matter of Everything: Twelve Experiments That Changed Our World, she looks back at the people who engineered ground-breaking experiments, and the human ingenuity, creativity and curiosity, as well as luck and serendipity that propelled them forward.While physicists attempt to describe and define the universe, the workings of the human mind still remain a challenge to scientists and philosophers. In The Book of Minds, the science writer Philip Ball looks at what we know about the minds of other creatures, from octopuses to chimpanzees, and of the workings of computers and alien intelligences. By understanding how minds differ, he argues, the better we can understand our own.Producer: Katy Hickman

In The Age of the Strongman, the journalist Gideon Rachman explores how populist and authoritarian leaders have become a central feature of global politics. Since Vladimir Putin took power in Russia at the beginning of the new millennium, self-styled strongmen have emerged across the globe, from Trump and Bolsonaro to Orbán, Xi and Modi. Rachman tells Tom Sutcliffe how these leaders have taken power and the challenge they pose to liberal democracy. Judy Dempsey is a senior fellow at Carnegie Europe and editor in chief of the Strategic Europe blog. She explains how Viktor Orbán has tightened his grip on power in Hungary, while the EU has dragged its heels. And how Putin’s war in Ukraine has not only exacerbated pre-existing global divisions but divided Europe as well. History is littered with powerful leaders, and Christopher de Bellaigue, tells of the rise of one of the most feared – Suleyman the Magnificent. In The Lion House: The Coming of a King the 16th century Ottoman Sultan dominates the lives of those from Baghdad to the walls of Vienna.Producer: Katy Hickman

The new novel, Glory, by prize winning writing NoViolet Bulawayo is a postcolonial tale of power and tyranny – an African Animal Farm. It’s set in the fictional Jidada, that resembles Zimbabwe during the overthrow of Robert Mugabe, and is populated by a vivid cast of animals – from the vicious dog-soldiers to the powerful Old Horse leader himself. She tells Adam Rutherford how her chorus of animal voices help reveal the human world more clearly. The journalist Dipo Faloyin wants to push against harmful stereotypes of modern Africa. In his latest book, Africa Is Not A Country, he argues that a continent of over 1.4 billion people, 54 countries and more than 2,000 languages has been reduced to a simplistic story. He looks at how politics, culture and community have emerged in different ways across Africa.Julia Gallagher is Professor of African Politics at SOAS, University of London. Her research explores the architecture of state buildings in different African countries – from the re-purposed colonial structures to the new palatial palaces of post-independence – and how citizens respond to them. Also as the African Union celebrates twenty years since it was founded – housed in a new compound built by the Chinese in Addis Ababa – she looks at the position of the AU in the 21st century.
