Uncharted with Hannah Fry

Behind every line on a graph, there lies an extraordinary human story. Mathematician Hannah Fry is here to tell us ten of them. 

Uncharted with Hannah Fry will lead us through ten captivating mysteries to reveal the power of numbers behind each one. Along the way we discover the remarkable people who followed the data and unearthed something extraordinary.

Introducing... Uncharted with Hannah Fry

It’s 1973 and the UK is in crisis: runaway inflation, industrial strike action and political turmoil. Unnoticed at the time - in hospitals and front rooms around the country - something odd is happening with the country’s newborns. A higher proportion of boys are being born than ever before in the 20th Century. What was behind this puzzling trend? 

Hannah Fry follows one researcher’s obsessive mission to unravel the mystery.

1. The Returning Soldier

In 1998, the climate scientist Michael Mann published a simple graph shaped like an ice hockey stick: a long straight line which curves suddenly upward at the end. It was based on decades of intrepid work by scientists around the world. But the line held a stark warning. For Michael, notoriety, abuse and a global battle over the reality of climate change followed. 
 
Hannah Fry tells the remarkable story of the people behind the hockey stick: the scientists who scaled mountains and braved oceans in search of evidence, and the dramatic fallout when the world saw what they had found.

2. The Hockey Stick

It’s a hot summer’s day in 1998. Two couples stand side by side in a small courtyard. Brought together by chance, they may never have met if not for one thing. A tatty piece of paper, the contents of which will change their lives, and the lives of thousands across the country, forever. 

Hannah Fry tells the tale of this single sheet of A4 uncovered a dark pattern and a serial murderer hiding in plain sight.

The train company, the government, even the military are at a loss: no-one can figure out what is causing the problem. Until Jason Bay and his team of data scientists assemble an old-fashioned timetabling graph, first developed in 19th century France, which exposes an invisible culprit.

Behind every line on a graph, there lies an extraordinary human story. And mathematician Hannah Fry is here to tell us ten of them.
