The Rest Is Science

Is deception a uniquely human trait, or is the natural world built on a foundation of fraud? When a cuttlefish shifts its skin to mimic a female and sneak past a rival male, this may be deceptive but is it telling a lie?

Professor Hannah Fry and VSauce's Michael Stevens explore the evolutionary biology of dishonesty across the animal kingdom. What is the neurological difference between a biological reflex and a calculated bluff? What kind of cognitive processing is needed for true artifice, and are human beings the only creatures on earth who possess it?

Moving from tactical falsehoods by the Adélie Penguin, to the complex betrayals seen in Macaques and Great Apes, Hannah and Michael apply evolutionary game theory to the wild to evaluate the psychology of false signals and the battle between perception, manipulation, illusion and power.

Topologically speaking, a human is just a donut with seven holes. It sounds like a joke, but it is a fundamental biological reality. Professor Hannah Fry and Michael Stevens explore the strange geometry of the human body, tracing how we evolved from simple tubes into complex toruses. They investigate the "design flaw" at the boundary of our existence, the fragile transition where skin meets internal lining, and ask why nature built us with so many vulnerabilities to the outside world.But before mapping our topology, Michael and Hannah tackle the instability of knowledge itself. From the suggestion our current physics is almost certainly wrong, to the edges of logic where mathematics fundamentally breaks down. Plus, they unpack the hidden psychology of symmetry: why is the human brain so obsessed with centering pictures, and what does it tell us about how we order our reality?-------------------For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

It starts as a friendly challenge: who can name the biggest number?

The only rule? Infinity doesn’t count.

What follows is a journey through the biggest finite numbers ever imagined.



From Archimedes’ grains of sand to Graham’s Number, a sequence so vast it stretches the limits of human comprehension, Professor Hannah Fry and Michael Stevens tumble through this strange landscape of scale, tracing how mathematicians have pushed counting to its absolute edge.

But beyond vast calculations, perhaps this is less about numbers and more about us.

Why do humans push at the limits of finitude at all? How do we represent the biggest numbers in existence? Why can’t our brains feel the difference between a million, a billion, and a trillion? And when do big numbers affect our ability to empathise with others?

Can mathematics ever truly be proven? And can Michael's poetry help you remember some tricky equations?

In this episode, Professor Hannah Fry and Michael Stevens answer your questions and take a look at what it means for something to be true in mathematics. Starting with a grand attempt to prove that one plus one equals two, and into Gödel’s theorem that no system of maths can ever fully prove itself, they explore how maths connects to the real world, from an equation that predicts antimatter to the calculations that led to the discovery of Neptune. After the break, Michael shows off a set of limericks written and read by himself.

The Rest Is Science: Field Notes is released every Thursday, with Hannah and Michael exploring questions where mathematics, science, and human behaviour meet.

Is it possible to make a sport too good?

Professor Hannah Fry and Michael Stevens explore how science, data, and optimisation are transforming modern sports improving athletes and teams, while quietly changing how games are played, watched, and understood.

From the Tush Push in the NFL and defensive shifts in Major League Baseball, to dirty air in Formula 1, expected goals in Premier League football, and the statistical dominance of seven footers in the NBA, they examine how prediction, probability, and performance analysis reshape decision making on the pitch, the court, and the track.

Along the way, they wonder whether the heart of the games we love are defined by 'unnecessary obstacles', how prediction and probability have reshaped decision making, and why humans might enjoy watching messy problems unfold on the pitch much more than optimised solutions.
