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

Horizon: Inside the Social Network – Facebook’s Difficult Year

Following the teams inside Facebook, revealing a hidden technological playground. The film tackles difficult questions, like how our data is used, and also shows how Facebook works

Facebook is a company that has grown from nothing to be worth half a trillion dollars in just 15 years. Today nearly a third of all humans are using it, and yet we rarely get to see the people actually in charge of the biggest social network in the world.

The company has suffered a series of deepening scandals and intense media scrutiny. In 2018, their mission – to connect everyone on the planet – seemed to be going dramatically … Ler mais
