Blood Of The Vikings: The Sea Road

   2001    History
Julian Richards investigates the impact of the Vikings in Britain. This edition focuses on the archaeological trail left by the Vikings as they travelled from Norway along the sea road to Dublin. Settlements, a boat burial and evidence of trading have been discovered on the Scottish isles, and silver hoards found in Ireland suggest that Dublin was not only wealthy and important, but also a centre for trade in slaves.

Numbers as God

   2018    Science
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. To investigate this question, Hannah goes head first down the fastest zip wire in the world to learn more about Newton's law of gravity, she paraglides to understand where the theory of maths and its practice application collide, and she travels to infinity and beyond to discover that some infinities are bigger than others.
In this episode, Hannah goes back to the time of the ancient Greeks to find out why they were so fascinated by the connection between beautiful music and maths. The patterns our ancestors found in music are all around us, from the way a sunflower stores its seeds to the number of petals in a flower. Even the shapes of some of the smallest structures in nature, such as viruses, seem to follow the rules of maths. All strong evidence for maths being discovered. But there are those who claim maths is all in our heads and something we invented. To find out if this is true, Hannah has her brain scanned. It turns out there is a place in all our brains where we do maths, but that doesn't prove its invented.
Experiments with infants, who have never had a maths lesson in their lives, suggests we all come hardwired to do maths. Far from being a creation of the human mind, this is evidence for maths being something we discover. Then along comes the invention of zero to help make counting more convenient and the creation of imaginary numbers, and the balance is tilted in the direction of maths being something we invented. The question of whether maths is invented or discovered just got a whole lot more difficult to answer

The DNA Switch

   2019    Medicine    HD
Destiny is beyond our control, our fate already set, perhaps from the onset of disease or being born with a special ability. You may think our lives are determined by the genes we're born with, but that is not the case. In the non-coding 98% of our DNA, we have countless switches to promote or suppress the physiological reactions of our bodies. Interestingly, we can change the states of these switches through our own efforts and even can affect the DNA conditions of our offspring before their birth.

Fusion

   2020    Technology
It is the greatest technological challenge ever undertaken by humankind. The quest to produce the ultimate energy solution, Fusion, a reliable source of clean power. What if we could create here on earth, our very own version of a star, a machine that makes power from nuclear fuel? But so immense are the challenges, the goal of a power-producing fusion reactor has so far remained elusive and out of reach... until now.

Einstein Biggest Blunder

   2000    Science
At the dawn of a new century, a new theory is being born. It threatens to demolish the foundations of 20th century physics. Its authors are two of the world's leading cosmologists. If they're right, Einstein was wrong. It all began when Andy Albrecht and Joao Magueijo met at a conference in America in 1996. This program began from Newtonian view of the universe then takes you through the General Relativity and the Flatness problem. This leads to the Horizon problem and its solution, the Inflation theory. However modern astronomy doesn't stop here, the Inflation theory has its flaw too, and what happened before the big bang? This can all be answered by changing one thing, the one thing no body dare to question until now.

The Cambridgeshire Crucifixion

       History
The documentary tells the story of the extremely rare discovery of evidence of Roman crucifixion, unearthed in a routine archaeological dig in the Cambridgeshire Fens. When human remains were found alongside a variety of Roman artifacts, none of the team at Albion Archaeology saw anything out of the ordinary. But once the bones were washed back at HQ, something highly unusual was uncovered: a nail through the heel bone of one of the individuals. Could this be evidence of a Roman crucifixion? When they did some research, they found that only one confirmed example had ever been unearthed before, discovered in the 1960s in Jerusalem. To find out more, they called in renowned osteoarchaeologist Dr Corinne Duhig to investigate. With exclusive access to Corinne’s investigation and the remains themselves, The Cambridgeshire Crucifixion sets out to find out who this person was, how they lived and why they were put to death in this notoriously gruesome way. We perform a CT scan, DNA and isotope analysis of the remains, and use them to create a cutting-edge virtual autopsy of the skeleton, conducted by Corinne and one of her former students, biologist Prof Ben Garrod.
A supporting cast of expert contributors help to analyse the artefacts found at the Fenstanton site and reveal a compelling picture of life in Roman Britain in the 1st century CE. The film culminates in a world first: a full forensic facial reconstruction of a victim of Roman crucifixion, conducted by world-leading expert Joe Mullins.
