These days we’re bombarded with information and claims that purport to explain almost every conceivable aspect of our lives, be it down to the bold assertions made by policymakers, the confidence of anonymity afforded by social media or just our natural human inclination to be fooled by a well-spoken know-it-all. But exactly who are the people making these claims, how do they reach their conclusions, and really, can anyone ever actually be certain about anything?
In this episode, we catch up with the statistician, epidemiologist and author Adam Kucharski to take about his latest book Proof, The Uncertain Science of Uncertainty.
He tells us how Abraham Lincoln’s background as lawyer led him to study the nature of proof beyond reasonable doubt and how it helped him to win his presidency, how picking holes in previous logical thinking enabled Albert Einstein to discover some of his greatest theories, and what the COVID pandemic taught us all about the value of scientific rigour and evidence-based conclusions.

How AI is helping us to understand how our brains learn
The human brain is surely one of the most complex and fascinating creations in all of nature. It’s through them that we experience the world around us, develop knowledge and skills, and carry within us memories of events and experiences that occurred decades in the past, which we can later draw on to face new challenges.
But when it comes to understanding exactly what is going on between our ears, we’re only just starting to scratch the surface. Could artificial intelligence technology help us in this quest?
In this episode, we’re joined by Prof Andrew Saxe, a computational neuroscientist based at University College London.
He tells us about the work his lab is carrying out on modelling the function of our brains using artificial intelligence, what this research has already uncovered about how our brains learn and what we can look forward to discovering in the coming decade or so.
Andrew is a finalist for the Blavatnik Awards for Young Scientists.

What our coastlines can tell us about the planet’s past and future
From the dramatic caves that bring to mind the pirates and smugglers of yore to the rolling sand dunes many of us likely played in as children, our coastlines are home to all manner of fascinating features, forged over centuries by crashing waves and harsh, unforgiving weather. But far from simply being picturesque, these landmarks can teach us about our planet’s past and ultimately, its future.
In this episode, we speak to writer and author Matthew Yeomans about his latest book Seascape: Notes from a Changing Coastline.
He speaks to us about the observations he made of the many and varied effects of climate change while walking along the Welsh coastline, how the threat of coastal flooding is very real and how nature-based solutions may well be the most effective way of protecting our precious coastlines.

How to see through misleading numbers and statistics
Whether it’s from our friends, workmates or via various media platforms, both social and traditional, these days we’re all faced with a never-ending bombardment of information expressed through numbers, percentages and statistics. But how exactly should we go about interpreting them?
In this episode we catch up with Prof Sir David Spiegelhalter, a statistician and science communicator based at the University of Cambridge.
He shares some simple advice to help us understand how the risks and benefits of various lifestyle factors such as exercise and diet are presented to us, explains how framing can be used to make any number look big or small, and tells us what everyone, including scientists, could be doing better when we speak about numbers.
