The Rest Is Science

Why does one of the most familiar numbers on a nutrition label turn out to be far more complicated than it looks?

What can a can of fizzy drink teach us about thermodynamics, human metabolism, and the strange ways scientists measure energy?

Professor Hannah Fry and VSauce’s Michael Stevens dive into the weird science of calories. From century-old experiments involving fire, body heat, and human digestion to the hidden quirks of modern food labelling.

Do “negative calorie” foods really exist? Where does burned fat actually go? Why chewing matters more than you’d think, and how your body is constantly leaking energy out into the universe.

What if the universe is recording everything you’ve ever seen and done?

In this episode, Hannah Fry and Michael Stevens explore the idea that light itself might carry a record of the past. And if it did, how could we watch history unfold by capturing it.

Could a perfectly placed mirror or even a black hole bend that ancient light back to us? Could we watch the pyramids being built, or hear Einstein’s final words?

From a nano-second old reflection in a mirror to the photons drifting through billions of miles of space, they reveal how everything we see is already gone, and uncover surprising truths about time, perception, and our own DNA.

What can a humble airplane sick bag teach us about physics, engineering, and the limits of the human stomach; And why are there people out there collecting thousands of them?

Professor Hannah Fry and VSauce’s Michael Stevens turn an unlikely holiday prompt into a surprisingly rich exploration of flight. From the biology of motion sickness to the physics of turbulence, and from exploding crisp packets to next-generation aircraft design, they unpack how flying messes with your body and how science has made it (mostly) better.

How does a perfectly symmetrical ball of cells become an animal, with a head, a tail, and complex zebra or leopard like patterns?

In this episode, we dive into the mind bending science of how order emerges from chaos, guided by an unexpected genius: Alan Turing.

From leopard spots and human embryos to crime hotbeds, Hannah and Michael discover the hidden mathematical rules shaping life itself…and the ethical dilemmas that come with them.
