Edison: The Father of Invention

Explores the complex alchemy that accounts for the enduring celebrity of America’s most famous inventor

By the time he died in 1931, Thomas Edison was one of the most famous men in the world. The holder of more patents than any other inventor in history, Edison had amassed a fortune and achieved glory as the genius behind such revolutionary inventions as sound recording, motion pictures, and electric light. When Edison died on October 18, he lay in state for two days in the library of his West Orange complex, as thousands of people lined up … Ler mais

Horizon: Strange Signals from Outer Space!

Horizon investigates unusual space signals including the Lorimer Burst, and has exclusive access to researchers at the Green Bank Telescope searching for signals from Tabby's Star

For decades some have suspected that there might be others out there, intelligent beings capable of communicating with us, even visiting our world. It might sound like science fiction, but today scientists from across the globe are scouring the universe for signals from extraterrestrials.

In 2006, husband and wife team Duncan Lorimer and Maura McLaughlin discovered an enigmatic signal from space, known as a fast radio burst. It was a pulse of radiation so bright, it didn’t appear to … Ler mais

Horizon: Seeing Stars

Horizon follows the astronomers pushing the limits of science and engineering with a new generation of supertelescopes in the hunt for mysterious objects in the universe

Around the world, a new generation of astronomers are hunting for the most mysterious objects in the universe. Young stars, black holes, even other forms of life.

They have created a dazzling new set of supertelescopes that promise to rewrite the story of the heavens.

This film follows the men and women who are pushing the limits of science and engineering in some of the most extreme environments on earth. But most strikingly of all, no-one really knows what they … Ler mais

Horizon: Secrets of the Star Disc

"It’s the find of a lifetime. Indeed, the find of several lifetimes." - Professor Miranda Aldhouse-Green, University of Wales

This is the extraordinary story of how a small metal disc is rewriting the epic saga of how civilisation first came to Europe, 3600 years ago.

When grave robbers ransacked a Bronze Age tomb in Germany, they had no idea that they had unearthed the find of a lifetime. But they knew that it was worth selling. It was a small bronze disc of exquisite design. So they contacted the archaeologist Harald Meller, offering to sell it to him … Ler mais

Horizon: Secrets of the Solar System

A look at how new planets being discovered are forcing scientists to rewrite the history of our own solar system

New planets are now being discovered outside our solar system on a regular basis, and these strange new worlds are forcing scientists to rewrite the history of our own solar system. Far from a simple story of stable orbits, the creation of our solar system is a tale of hellfire, chaos and planetary pinball.

It’s a miracle our Earth is here at all.

Horizon: Science Under Attack

Nobel Prize winner Sir Paul Nurse examines why science appears to be under attack, and why public trust in key scientific theories has been eroded

Nobel Prize winner Sir Paul Nurse examines why science appears to be under attack, and why public trust in key scientific theories has been eroded – from the theory that man-made climate change is warming our planet, to the safety of GM food, or that HIV causes AIDS.

He interviews scientists and campaigners from both sides of the climate change debate, and travels to New York to meet Tony, who has HIV but doesn’t believe that that the … Ler mais

Horizon: The Mystery of Dark Energy

Horizon looks at dark energy - the mysterious force that is unexpectedly causing the universe's expansion to speed up

The effects of dark energy were discovered in 1998, but physicists still don’t know what it is. Worse, its very existence calls into question Albert Einstein‘s general theory of relativity – the cornerstone of modern physics.

The hunt for the identity of dark energy is on. Experiments on earth and in space generate data that might provide a clue, but there are also hopes that another Einstein might emerge – someone who can write a new theory explaining the … Ler mais

Trillion Dollar Bet

The film tells the fascinating story of the invention of the Black-Scholes Formula, a mathematical Holy Grail that forever altered the world of finance and earned its creators the 1997 Nobel Prize in Economics

In 1973, three brilliant economists, Fischer Black, Myron Scholes, and Robert Merton, discovered a mathematical Holy Grail that revolutionized modern finance. The elegant formula they unleashed upon the world was sparse and deceptively simple, yet it led to the creation of a multi-trillion dollar industry. Their bold ideas earned Scholes and Merton a Nobel Prize (Black died before the prize was awarded) and attracted the elite of Wall Street.

In 1993, Scholes and Merton joined forces … Ler mais

Horizon: The Midas Formula

A beautiful mathematical formula that changed the world

This is the extraordinary story of a beautiful mathematical formula that changed the world, the financial markets, and indeed capitalism itself. It could do the unthinkable – it took the risk out of playing the money-markets. To its inventors it brought the Nobel Prize for economics. To those who used it, it brought great wealth. But this glittering tale would end in tragedy.

The Black Scholes formula was invented 25 years ago, by three young mathematicians. They had been … Ler mais

Horizon: Is Everything We Know About The Universe Wrong?

Investigating the discovery of what is ominously being called 'dark flow', a phenomenon which could mean scientists might have to find a new way of understanding the universe

There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner.

Sasha Kashlinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow‘ not only … Ler mais
