Drowing by Numbers

At the heart of the climate change debate is a paradox - we've never had more information about our changing climate, yet surveys show that the public are, if anything, getting less sure they understand what's going on. This programme aims to remedy that, with a new perspective on the whole subject. Presented by three mathematicians - Dr Hannah Fry, Prof Norman Fenton and Prof David Spiegelhalter - it hones in on just three key numbers that clarify all the important questions around climate change. The stories behind these numbers involve an extraordinary cast of characters, almost all of whom had nothing to do with climate change, but whose work is critical to our understanding of the climate.

History by the Numbers is an energetic, fast-paced series that takes a global dive into the extraordinary and often overlooked numbers that have created our world’s history. Each episode delves into the numbers and over-the-top stats behind a different subject such as the massive growth of the global fast food empire, the wealth and bloodshed of the world’s top crime bosses, the herculean numbers behind Mount Everest, and the lives of the richest people on earth.

Earth's climate is changing - understanding how has become one of the biggest scientific projects ever undertaken.

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the Internet, and "big data," the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? In a fascinating, fast-paced investigation, NOVA takes viewers from the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election.

Using recorded figures and statistics to outline the full extent of the conflict, explaining the horrors of war and how it ever came to take place.

Hannah explores a paradox at the heart of modern maths, discovered by Bertrand Russell, which undermines the very foundations of logic that all of maths is built on. These flaws suggest that maths isn't a true part of the universe but might just be a human language - fallible and imprecise. However, Hannah argues that Einstein's theoretical equations, such as E=mc2 and his theory of general relativity, are so good at predicting the universe that they must be reflecting some basic structure in it. This idea is supported by Kurt Godel, who proved that there are parts of maths that we have to take on faith.

Strength in Numbers is a rally call to connect all mountain bikers, regardless of location or language or discipline. Tire to ground, foot to pedal, hand to bar - communities drawn together by trails of dirt.

Documentary series in which Dr Hannah Fry explores the mystery of maths. Is it invented like a language or is it discovered and part of the fabric of the universe? In this new series, mathematician Dr Hannah Fry explores the mystery of maths. It underpins so much of our modern world that it's hard to imagine life without its technological advances, but where exactly does maths come from? Is it invented like a language or is it something discovered and part of the fabric of the universe? It's a question that some of the most eminent mathematical minds have been wrestling with.

After viewing this provocative documentary, you will never look at Wikipedia the same way. Filmmakers Scott Glosserman and Nic Hill engagingly explore the history and cultural implications of one of the most traveled and referenced sites on the Internet. A whole range of opinion is expressed about the impact of Wikipedia on the archiving of learning, from interviews with founder Jimmy Wales to commentators suspicious of the site's supposed neutrality. The documentary delves into the EssJay controversy in which a Wikipedian made false claims about his academic credentials and the battle over journalist John Seigenthaler's inaccurate entry.
