Where Am I? Is a new documentary about the skills we use to find our way around. Whether you are an Inuit hunter, a foraging insect, or just someone out for a stroll, your brain is performing one of its most fundamental services – it’s navigating. Why are some of us good at finding our way, while others are not? Good navigators are able to use both memory and imagination…remembering where they have been, and imagining where they’re going. Some researchers believe we build a cognitive or mental map when we navigate, a kind of bird’s eye view of our surroundings, a view that can be rotated and examined in our mind. There has been about sixty years of argument amongst scientists about whether humans and other mammals actually form these cognitive maps or not. The advent of GPS or Global Positioning Systems has changed the discussion about navigation. GPS triggers a simpler, more automatic navigational technique that does not involve building a mental map. With GPS, we simply respond to directions and may not truly understand where we are.
Ninety years after the historic double-slit experiment, the quantum revolution shows no sign of slowing. Join a vibrant conversation with renowned leaders in theoretical physics, quantum computation, and philosophical foundations, focused on how quantum physics continues to impact understanding on issues profound and practical, from the edge of black holes and the fibers of spacetime to teleportation and the future of computers.
Nuclear energy might have a lot of unused potential. Not only is it one of the best mid term solutions for global warming bit despite what gut feeling tells us, it has saved millions of lives. By investing more into better technologies we might be able to make nuclear energy finally save and clean forever.
The story of an extraordinary scientific adventure - the attempt to control gravity. For centuries, the precise workings of gravity have confounded the greatest scientific minds, and the idea of controlling gravity has been seen as little more than a fanciful dream. Yet in the mid 1990s, UK defence manufacturer BAE Systems began a groundbreaking project code-named Greenglow, which set about turning science fiction into reality. On the other side of the Atlantic, Nasa was simultaneously running its own Breakthrough Propulsion Physics Project. It was concerned with potential space applications of new physics, including concepts like 'faster-than-light travel' and 'warp drives'. Horizon explores science's long-standing obsession with the idea of gravity control. It looks at recent breakthroughs in the search for loopholes in conventional physics and examines how the groundwork carried out by Project Greenglow has helped change our understanding of the universe.
