Comedian Ben Miller returns to his roots as a physicist to try to answer a deceptively simple question: what is one degree of temperature? His quest takes him to the frontiers of current science as he meets researchers working on the hottest and coldest temperatures in the universe, and to a lab where he experiences some of the strangest effects of quantum physics - a place where super-cooled liquids simply pass through solid glass. Plus, Ben installs his very own Met office weather station at home. Ben's investigations in this personal and passionate film highlight the importance of measurement and accuracy in the 21st century.

Black holes are one of the most destructive forces in the universe, capable of tearing a planet apart and swallowing an entire star. Yet scientists now believe they could hold the key to answering the ultimate question - what was there before the Big Bang? The trouble is that researching them is next to impossible. Black holes are by definition invisible and there's no scientific theory able to explain them. Despite these obvious obstacles, Horizon meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe.

Many people know the basic rules of chess, but few can play really well. This programme offers some essential tips on how to raise our game. British grandmasters Dan King and Ray Keene go through a special demonstration game from opening gambit to checkmate, revealing the key moves that can lead to victory. They explain the opening, middle and end games, and how to outwit an opponent with techniques such as forks, pins and skewers. Along the way the colourful and diverse world of British chess playing is celebrated, including speed chess and chess boxing, and useful advice is offered on how not to be humiliated by a child prodigy. Also taking part are novelist Martin Amis, writer Dominic Lawson, Britain's youngest grandmaster David Howell and under-16 champion Sheila Dines.

Great Wall Across the Yangtze

Mysteriously beautiful fractals are shaking up the world of mathematics and deepening our understanding of nature. You may not know it, but fractals, like the air you breathe, are all around you. Their irregular, repeating shapes are found in cloud formations and tree limbs, in stalks of broccoli and craggy mountain ranges, even in the rhythm of the human heart. In this film, we takes viewers on a fascinating quest with a group of maverick mathematicians determined to decipher the rules that govern fractal geometry. For centuries, fractal-like irregular shapes were considered beyond the boundaries of mathematical understanding. Now, mathematicians have finally begun mapping this uncharted territory. Their remarkable findings are deepening our understanding of nature and stimulating a new wave of scientific, medical, and artistic innovation stretching from the ecology of the rain forest to fashion design. The documentary highlights a host of filmmakers, fashion designers, physicians, and researchers who are using fractal geometry to innovate and inspire.

A documentary about the speed of light, the ultimate speed limit enforced by the laws of the universe, and how scientists are looking for ways to exceed it; a look at what happens when we reach the
