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

Drowning in Plastic

   2018    Nature
Our blue planet is facing one its biggest threats in human history. Trillions of pieces of plastic are choking the very lifeblood of our earth, and every marine animal, from the smallest plankton to the largest mammals, is being affected. But can we turn back this growing plastic tide before it is too late? Wildlife biologist Liz Bonnin visits scientists working at the cutting edge of plastics research. She works with some of the world's leading marine biologists and campaigners to discover the true dangers of plastic in our oceans and what it means for the future of all life on our planet, including us.
Liz travels to a remote island off the coast of Australia that is the nesting site for a population of seabirds called flesh-footed shearwaters. Newly hatched chicks are unable to regurgitate effectively, so they are filling up on deadly plastic. She visits the Coral Triangle that stretches from Papua New Guinea to the Solomon Islands to find out more from top coral scientists trying to work out why plastic is so lethal to the reefs, fragile ecosystems that contain 25 per cent of all marine life.

An Honest Liar

   2014    History
A feature documentary about the world-famous magician, escape artist, and world-renowned enemy of deception, James 'The Amazing' Randi. The film brings to life Randi's intricate investigations that publicly exposed psychics, faith healers, and con-artists with quasi-religious fervour. A master deceiver who came out of the closet at the age of 81, Randi created fictional characters, fake psychics, and even turned his partner of 25 years, the artist Jose Alvarez, into a sham guru named Carlos. But when a shocking revelation in Randi's personal life is discovered, it isn't clear whether Randi is still the deceiver - or the deceived.

Unacknowledged

   2017    Culture
The film focuses on the historic files of the Disclosure Project and how UFO secrecy has been ruthlessly enforced-and why. The best evidence for extra-terrestrial contact, dating back decades, is presented with direct top-secret witness testimony, documents and UFO footage, 80% of which has never been revealed anywhere else. The behind-the-scenes research and high-level meetings convened by Dr. Steven Greer will expose the degree of illegal, covert operations at the core of UFO secrecy.
From briefings with the CIA Director, top Pentagon Generals and Admirals, to the briefing of President Obama via senior advisor John Podesta, chairman of the Hillary Clinton Campaign, we take the viewer behind the veil of secrecy and into the corridors of real power where the UFO secrets reside. The viewer will learn that a silent coup d'├ętat has occurred dating back to the 1950s and that the Congress, the President and other world leaders have been sidelined.

Whose Streets

   2017    Culture
Told by the activists and leaders who live and breathe this movement for justice, Whose Streets? is an unflinching look at the Ferguson uprising. When unarmed teenager Michael Brown is killed by police and left lying in the street for hours, it marks a breaking point for the residents of St. Louis, Missouri.
Grief, long-standing racial tensions and renewed anger bring residents together to hold vigil and protest this latest tragedy. Empowered parents, artists, and teachers from around the country come together as freedom fighters. As the national guard descends on Ferguson with military grade weaponry, these young community members become the torchbearers of a new resistance. Whose Streets? is a powerful battle cry from a generation fighting, not for their civil rights, but for the right to live.
