Forget oil, coal and gas - a new set of materials is shaping our world and they're so bizarre they may as well be alien technology. In the first BBC documentary to be filmed entirely on smartphones, materials scientist Prof Mark Miodownik reveals the super elements that underpin our high-tech world. We have become utterly dependent on them, but they are rare and they're already running out. The stuff that makes our smartphones work could be gone in a decade and our ability to feed the world depends mostly on a mineral found in just one country. Mark reveals the magical properties of these extraordinary materials and finds out what we can do to save them.
On November 25th, 1915, Einstein published his greatest work: general relativity. The theory transformed our understanding of nature’s laws and the entire history of the cosmos, reaching back to the origin of time itself. Now, in celebration of the 100th anniversary of Einstein’s achievement, NOVA tells the inside story of Einstein’s masterpiece. The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.”
In episode one, Helen ventures to the bottom of the temperature scale, revealing how cold has shaped the world around us and why frozen doesn't mean what you might think. She meets the scientists pushing temperature to the very limits of cold, where the normal laws of physics break down and a new world of scientific possibility begins. The extraordinary behaviour of matter at temperatures close to absolute zero is driving the advance of technology, from superconductors to quantum computing.
