The Genius of Marie Curie – The Woman Who Lit Up the World

Multi-layered documentary revealing the human story of Marie Curie, whose pioneering research on radioactivity made her the world's most famous female scientist

Over 80 years after her death, Marie Curie remains by far the best-known female scientist. In her lifetime, she became that rare thing – a celebrity scientist, attracting the attention of the news cameras and tabloid gossip. They were fascinated because she was the first woman to win the Nobel Prize and is still the only person to have won two Nobels in two different sciences. But while the bare bones of her scientific life, the obstacles she had to … Ler mais

To Infinity and Beyond

Horizon examines the story of infinity – older than time, bigger than the universe and stranger than fiction

By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like an perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.

Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more … Ler mais

Nature’s Mathematics

Patterns, shapes, and colours

Nature follows a number of intricate and subtle mathematical rules to produce the patterns, shapes, and colours that we find so mesmerizing.

Episode 1

Wherever we find patterns and symmetry in nature, we also find that nature conforms to certain rules. Rules that combine elegance with efficiency. Rules that shape trees and river estuaries alike, and that continue to baffle scientists by their often unfathomable ubiquity.

Episode 2 >>… Ler mais

Ancient Computer

A Greek shipwreck holds the remains of an intricate bronze machine that turns out to be the world's first computer

In 1900, a storm blew a boatload of sponge divers off course and forced them to take shelter by the tiny Mediterranean island of Antikythera. Diving the next day, they discovered a 2,000 year-old Greek shipwreck. Among the ship’s cargo they hauled up was an unimpressive green lump of corroded bronze.

Rusted remnants of gear wheels could be seen on its surface, suggesting some kind of intricate mechanism. The first X-ray studies confirmed that idea, but how it worked … Ler mais

Rise of the Robots

How will human-like robots change our future and how we see ourselves?

They run our factory assembly lines and make our coffee. But humanoid robots — machines with human-like capabilities — have long been the stuff of science fiction. Until now.

Fueled by an ambitious DARPA challenge, the race is on to design a robot that can replace humans in disaster relief situations. Follow the robots and the engineers that program them as they strive to make their way out of the lab and into the real world. But how capable … Ler mais

What Is Reality?

The quest to explain the nature of reality is one of the great scientific detective stories. Are we are part of a cosmic hologram? Do we exist in an infinity of parallel worlds?

There is a strange and mysterious world that surrounds us, a world largely hidden from our senses. The quest to explain the true nature of reality is one of the great scientific detective stories.

Clues have been pieced together from deep within the atom, from the event horizon of black holes, and from the far reaches of the cosmos. It may be that that we are part of a cosmic hologram, projected from the edge of the universe. Or that … Ler mais

Leonardo: The Man Who Saved Science

Leonardo da Vinci is well known for his inventions as well as his art. But new evidence shows that many of his ideas were realized long before he sketched them out in his notebooks — some even 1,700 years before. Was Leonardo a copycat?

Leonardo da Vinci is, of course, best known as one of the world’s greatest artists. At his death in 1519, he was famous for such masterpieces as the Mona Lisa and The Last Supper. But he was more than a painter, he was also a musician, writer, and showman. In the pages of his notebooks, written in a secretive reverse script, and unpublished for more than 400 years, we discover yet another Leonardo, the man of science.

His notebooks … Ler mais

Dancing in the Dark – The End of Physics?

A look at dark matter and dark energy ahead of the Large Hadron Collider being switched on in March 2015, having been upgraded

Scientists genuinely don’t know what most of our universe is made of. The atoms we’re made from only make up four per cent. The rest is dark matter and dark energy (for ‘dark’, read ‘don’t know’). The Large Hadron Collider at CERN has been upgraded. When it’s switched on in March 2015, its collisions will have twice the energy they did before. The hope is that scientists will discover the identity of dark matter in the debris.

The stakes are … Ler mais

Project Greenglow – The Quest for Gravity Control

The story of an extraordinary scientific adventure – the attempt to control gravity. The dream of flying cars and journeys to the stars no longer seems quite so distant

This is the story of an extraordinary scientific adventure – the attempt to control gravity. For centuries, the precise workings of gravity have confounded the greatest scientific minds – from Newton to Faraday and Einstein – and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a ground-breaking project code-named Greenglow, which set about turning science fiction into reality. On the other … Ler mais
