Artificial Intelligence will be the focus of this year’s Royal Institution Christmas Lectures by the Oxford Professor of Computer Science, Mike Wooldridge. In his series of lectures (broadcast on BBC Four in late December) he will attempt to disentangle the realities from the myths, but will also demonstrate the huge impact AI is already having in fields ranging from medicine to football to astrophysics, as well as on the creative arts.

The bestselling novelist Naomi Alderman has fun with AI and its tech trillionaire-creators in her latest thriller The Future. While the wealthy corporate heads are effectively decapitated by an end-of-the-world scenario, the story explores whether the technology that could presage the apocalypse can also be used for the good of society.

The Professor of Politics at Cambridge, David Runciman, wants to change the way people think about a future in which artificial intelligence has taken control. In The Handover he looks back to the formation of states and corporations, arguing that these are the precursors to AI: powerful artificial entities that have come to rule our world. While thy have made us richer and safer, he questions what will happen to human existence if these two machines – states and AI – join forces.

With the fall of the Soviet Union, the theoretical physicist Armen Sarkissian returned home and became first the Prime Minister and then the President of the newly reformed state of Armenia. In his book, The Small States Club: How Small Smart States Can Save the World, he argues that successful smaller nations have had to learn to be more agile, adaptive and cooperative, compared to the world’s ‘greater’ powers.

The world map has changed considerably, especially in the 19th and 20th century, as empires fell apart and smaller nations fought for independence. The Canadian historian Margaret MacMillan looks back at this time, and considers how small states survive during times of conflict. In 2018 she presented the BBC’s Reith Lectures, The Mark of Cain, on the tangled history of war and society.

The BBC’s Chief International Correspondent Lyse Doucet is no stranger to conflict in the world, as she has covered all the major stories across the Middle East and North Africa for the past two decades. But she is also interested in the way small states have been instrumental in mediating world conflicts, and punching above their weight on international issues like the climate crisis.

It’s play time on Start the Week. The mathematician Marcus Du Sautoy looks at the numbers behind the games we play, from Monopoly to rock paper scissors. In Around The World in 80 Games he shows how understanding maths can give you the edge, and why games are integral to human psychology and culture.

The historian Anthony Bale looks at game-playing in the medieval world. In A Travel Guide to the Middle Ages, he finds travellers passing the time with dice and tric trac, as well as collecting pilgrim badges along the way.

Many of today’s most popular video games immerse players in historical settings, and the practice of collecting items along the way is nothing new to gamers. The co-director of the Games and Gaming Lab at the University of Glasgow, Jane Draycott, researches the historical authenticity of these online worlds, and especially the depiction of women.

And the mathematician G.T. Karber has taken his love of classic detective fiction and puzzles to create the murder-mystery riddle Murdle. A combination of Cluedo and Sudoku, what started as an online game is now a series of bestselling books. The latest is Murdle: More Killer Puzzles.

Tim Peake was the first British astronaut to visit the International Space Station, and is one of only 628 people in human history to have left the Earth’s atmosphere. In Space he tells the human story of space exploration – from launch to landing.

In Samantha Harvey’s latest novel Orbital six astronauts on a space station rotate above the Earth. While their waking lives are spent conducting scientific experiments and maintaining the spacecraft, their attention is constantly drawn back to the Earth – its beauty as they circle it, and the fragility of the human life on it.

The cosmologist Roberto Trotta stands on firm ground and gazes skyward. In Starborn he wonders how different our world would be if our ancestors had looked up and there were no stars. From navigation to time, gravity to the wonder of the universe, the cosmos has profoundly shaped our understanding of the world.
