Dr Hannah Fry explores a paradox at the heart of modern maths, discovered by Bertrand Russell, which undermines the very foundations of logic that all of maths is built on. These flaws suggest that maths isn't a true part of the universe but might just be a human language - fallible and imprecise. However, Hannah argues that Einstein's theoretical equations, such as E=mc2 and his theory of general relativity, are so good at predicting the universe that they must be reflecting some basic structure in it. This idea is supported by Kurt Godel, who proved that there are parts of maths that we have to take on faith. Hannah then explores what maths can reveal about the fundamental building blocks of the universe - the subatomic, quantum world. The maths tells us that particles can exist in two states at once, and yet quantum physics is at the core of photosynthesis and therefore fundamental to most of life on earth - more evidence of discovering mathematical rules in nature. But if we accept that maths is part of the structure of the universe, there are two main problems: firstly, the two main theories that predict and describe the universe - quantum physics and general relativity - are actually incompatible; and secondly, most of the maths behind them suggests the likelihood of something even stranger - multiple universes. We may just have to accept that the world really is weirder than we thought, and Hannah concludes that while we have invented the language of maths, the structure behind it all is something we discover. And beyond that, it is the debate about the origins of maths that has had the most profound consequences: it has truly transformed the human experience, giving us powerful new number systems and an understanding that now underpins the modern world.
David Attenborough reveals the surprising truth about the cold-blooded lives of reptiles and amphibians. These animals are as dramatic in combat, as colourful in their communication and as tender in their parental care as any other animals. Join giant courting crocodiles, jousting tortoises and bright red sumo-wrestling frogs in their sophisticated, solar-powered lives.
In the year 480 B.C., the Greeks and the Persians fight one of the most famous battles in history at a place called Thermopylae. Here, the mighty Persian war machine, which has conquered most of the known world, will attempt an expansion into Europe. The only thing standing in their way will be an army led by 300 Spartans, the greatest soldiers the world has ever known. They will fight to the very last man, and in doing so will protect the cradle of democracy during its infancy, and the battle will go down in history as the greatest military stand of all time.
The film uncovers the truth about how you really make decisions. Every day you make thousands of decisions, big and small, and behind all them is a powerful battle in your mind, pitting intuition against logic. This conflict affects every aspect of your life - from what you eat to what you believe, and especially to how you spend your money. And it turns out that the intuitive part of your mind is a lot more powerful than you may realise.
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.
The film looks at one of the most critical questions facing the world today-that of food security-and demonstrates the desperate need for common sense, solid information, and calm logical deliberation. Using the often angry and emotional controversy over genetically-modified foods as its entry point, Food Evolution shows how easily fear and misinformation can overwhelm objective, evidence-based analysis. Food Evolution takes the position that science and scientists hold the key to solving the food crisis. But whose science? In the GMO debate, both sides claim science is on their side. Who's right? How do we figure this out? What does this mean for the larger issues of food security, sustainability, and environmental well-being? Food Evolution seeks to answer these critically important questions.
