More or Less: Behind the Stats - Are quantum computers already super-powerful?

Google claim their latest quantum computer chip is able to process something in five minutes it would take a normal computer 10 septillion years to figure out.

As this is a massive amount longer than the entire history of the known universe, that seems to suggest the chip is extremely powerful.

But when you understand what?s going on, the claim doesn?t seem quite so impressive. Dr Peter Leek, a quantum computer scientist from Oxford University, explains the key context.

Start the Week - Climate Crisis: truth, lies and compromise

Every year world leaders gather at the United Nation’s COP (the Conference of Parties) to discuss how to work together on solutions to tackle climate change. And every year the wrangling lasts into the night as it becomes clear how difficult it is to achieve consensus. In Kyoto the playwrights Joe Murphy and Joe Robertson have recreated the drama, intrigue and power plays that resulted in one of COP’s greatest successes, the Kyoto Protocol from 1997. Kyoto is on at the Soho Place Theatre until May 2025.

Professor Mike Berners-Lee is an expert on the impact and footprint of carbon and has watched as countries see-saw on commitments to reduce the use of fossil fuels. In his latest book, A Climate of Truth he argues that we already have the technology to combat many of the problems, but what we’re lacking is the honesty – in our politics, our media, and our businesses – to make a real difference.

But how to save the planet is not necessarily straightforward. In The Shetland Way: Community and Climate Crisis on my Father’s Islands, Marianne Brown returns home after the death of her father. She finds the islanders at loggerheads over the construction of a huge windfarm: while some celebrate the production of sustainable energy, others argue the costs are too high for the environment and local wildlife.

More or Less: Behind the Stats - Did Trump make billions with his meme-coin?

Just before being inaugurated as US president for the second time, Donald Trump launched something called a ?meme-coin?. This is a bespoke cryptocurrency token featuring a picture of Donald Trump. A billion of them may eventually be created.

Newspaper headlines claimed that the Trump meme-coin had made the president billions of dollars wealthier. But it is far from clear that this is the case.

Start the Week - Music and movement; mind and body

Music as Medicine is the latest work by the neuroscientist and best-selling author Daniel Levitin. In it he explores the healing power of music, and the cutting edge research which examines how sound affects the brain. The dance critic Sara Veale is interested in movement. In Wild Grace she tells the untold history of the extraordinary women who were the pioneers of modern dance. While Nwando Ebizie is a practitioner of both music and movement, and is interested in using the latest neurological studies in her art. She will perform the works, Solve et Coagula (arr. Mark Knoop) and All the Calm of a Distant Sea at the Southbank Centre, London (23rd January) as part of the BBC Radio 3 Unclassified concert.

More or Less: Behind the Stats - Can redheads handle 25% more pain than brunettes?

What has the colour of your hair got to do with your capacity to withstand pain?

We investigate the claim, which regularly circulates on social media, that natural redheads are 25% tougher than their brunette peers.

Pain expert Jeff Mogil explains how it all comes down to something called MC1R.

Start the Week - Socrates, optimism and racism

In the first programme of the New Year Adam Rutherford follows two possible guides to a more fulfilled life – Socrates and optimism – but asks whether either has any answers to dealing with racism.

The philosopher Agnes Callard proposes the questioning Socratic method in Open Socrates: The Case for a Philosophical Life. She shows that this ancient method offers a new ethics to live by, from answering questions about identity and inequality, to helping us love and die well. But to truly flourish we also need a huge dose of optimism, according to the science writer Sumit Paul-Choudhury. In The Bright Side he argues that being optimistic is not only central to the human psyche, but plays a crucial role in overcoming the challenges of the twenty-first century.

The social psychologist Keon West is more sceptical. In his new book The Science of Racism, he challenges those – a reputed half of the population – who think that racism doesn’t exist. He goes back to the data and research to reveal the extent and prevalence of racist behaviour, and the repeated inadequacy of attempts to address it.

More or Less: Behind the Stats - Do 79% of Swedish asylum seekers go on holiday to the country they fled from?

The claim that 79% of asylum seekers in Sweden go on holiday in their home country has been repeated regularly on social media. It?s used to argue that recent refugees are being disingenuous about the danger they face in the country they have fled from. But when you look at the survey the claim is based on, you see the stat in a very different way. We speak to Hjalmar Strid, who ran the survey for polling company Novus, and Tino Sanandaji from Bulletin, the online news site which published it.

Start the Week - Human intelligence and imagination

Tom Sutcliffe and guests discuss how we solve problems and imagine the future. While many people now point to the potential of AI, the prize winning writer Naomi Alderman is interested in the messy magic of human thinking. In the forthcoming BBC Radio 4 series, Human Intelligence she tells the stories of the people – with all their ingenuity and foibles – who built the modern world.

Across history human cultures have devised a wide range of practices to understand, and discover, the mysteries of the past, present and future. The exhibition Oracles, Omens and Answers (at the Bodleian Library, Oxford, until April 2025), co-curated by Dr Michelle Aroney showcases the art of divination. From the use of cards, beads and spiders, to studying the stars, weather and palm lines people have sought ways to clarify and predict the world around them.

Human imagination is not just the tool of fiction writers, but something that’s vital to navigate the world; to reminisce, anticipate and plan for the future. But how does it work? The neurologist Adam Zeman explores the very latest scientific studies in the world of the imagination, in his new book, The Shape of Things Unseen.
