Director Kevin Macdonald and producer Ridley Scott team up to offer this candid snapshot of a single day on planet Earth. Compiled from over 80,000 YouTube submissions by contributors in 192 countries, Life in a Day presents a microcosmic view of our daily experiences as a global society. From the mundane to the profound, everything has its place as we spend 90 minutes gaining greater insight into the lives of people who may be more like us than we ever suspected, despite the fact that we’re separated by incredible distances.
When veteran broadcaster Alistair Cooke died in 2004 few suspected that he was yet to uncover his greatest story. What happened to his body as it lay in a funeral home would reveal a story of modern day grave robbery and helped smash a body-snatching ring that had made millions of dollars by chopping up and selling-off over 1000 bodies. Dead bodies have become big business.
Richard Hammond’s Invisible Worlds is a BBC television documentary programme presented by Richard Hammond that features state-of-the-art camera technology used to focus on what humans cannot see with the naked eye. It is one series long consisting of three episodes. 1. Speed Limits – Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. The human eye takes about fifty milliseconds to blink. But it takes our brain around a hundred and fifty milliseconds to process what we see.
Hyperland is a 50 minute long documentary film about hypertext and surrounding technologies written by Douglas Adams and produced by BBC Two in 1990. It stars Douglas Adams as a computer user and Tom Baker, with whom Adams already had worked on Doctor Who, as a software agent. The self proclaimed “fantasy documentary” begins with a shot of Adams asleep by the fire side with his television still on. In a dream, Adams, fed up by game shows, commercial and generally non-interactive linear content, takes his TV to a garbage dump, where he meets Tom, played by Tom Baker, a software agent that shows him the future of TV: Interactive Multimedia.

What if all the information in the world was categorized and easily searchable? What if all the news from around the world, all books, written texts, photos and videos that exist on a place in the world would be collected, and would be available everywhere? That is precisely the goal of Google and it will not be long for it to be realized.
Imagine if one minute from now, every single person on Earth disappeared. All 6.6 billion of us. What would happen to the world without humans? How long would it be before our nuclear power plants erupted, skyscrapers crumbled and satellites dropped from the sky? What would become of the household pets and farm animals? And could an ecosystem plagued with years of pollution ever recover?
The very notion is deliciously ghoulish: What happens to earth if – or when – people suddenly vanished? The History Channel presents a dramatic, fascinating what-if scenario, part science fiction and part true natural science. Welcome to Earth, Population: 0 is the catchy tagline, Life After People’s 94 minutes are so gripping you nearly forget while you watch that you, yourself, will be gone too. It turns out that earth can go along very nicely without us. The hardest part of the special is probably in the first 15 minutes, when pet owners confront what likely will happen to their dogs (thankfully, the show follows those dogs who break out of their houses, and the prognosis for them to survive as scavengers is good).
For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that. Dr Frank Drake was one of the leading lights in the new science of radio astronomy when he did something that was not only revolutionary, but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their new 25-meter radio telescopes at a star called Tau Ceti twelve light years from earth, hoping for signs of extra-terrestrial intelligence. Although project Ozma resulted in silence, it did result in one of the most seminal equations in the history of science – the Drake Equation – which examined seven key elements necessary for ET intelligence to exist, from the formation of stars to the likely length a given intelligent civilization may survive.
Ever since he was at school, actor and comedian Alan Davies has hated maths. And like many people, he is not much good at it either. But Alan has always had a sneaking suspicion that he was missing out.
In March 2002, the scientific world was rocked by some astonishing news: a distinguished US government scientist claimed he had made nuclear fusion out of sound waves in his laboratory. Rusi Taleyarkhan’s breakthrough was such important news because nuclear fusion is one of the most difficult scientific processes, and also one of the most coveted. It could solve all of our energy problems for ever.
Physicist Jim Al-Khalili travels through Syria, Iran, Tunisia and Spain to tell the story of the great leap in scientific knowledge that took place in the Islamic world between the 8th and 14th centuries. Its legacy is tangible, with terms like algebra, algorithm and alkali all being Arabic in origin and at the very heart of modern science – there would be no modern mathematics or physics without algebra, no computers without algorithms and no chemistry without alkalis. For Baghdad-born Al-Khalili this is also a personal journey and on his travels he uncovers a diverse and outward-looking culture, fascinated by learning and obsessed with science.
Series in which mathematician Marcus du Sautoy explores the stories behind some of the most familiar scientific diagrams. Vitruvian Man – He looks at Leonardo da Vinci’s world-famous diagram of the perfect human body, which has many layers from anatomy to architecture, and defines our species like no other drawing before or since. The Vitruvian Man, drawn in the 1480s when he was living and working in Milan, has become one of the most famous images in the world.
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia – how did we get here? In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science – how does a universe that starts off as dust end up with intelligent life?
Alan Davies discovers that answering that question is much harder than he originally thought after visiting mathematician Marcus du Sautoy to help him find an answer. However, this creates more questions, which requires a trip to a place dedicated to measurement, the National Physics Laboratory. Finding out the exact length of the string proves even more troublesome when Marcus proposes the string could be infinitely long, thanks to the theory of fractals .
Prior to the day in 1947 when test pilot Charles E. Chuck Yeager broke the sound barrier for the first time, people argued it wasn’t possible for a plane to fly that fast. So, perhaps we shouldn’t be deterred by the part of Einstein’s special theory of relativity that seemingly bars traveling at speeds faster than light. That said, cracking the light-speed barrier is vastly more complicated than going faster than sound. The aircraft that Yeager used to break Mach 1, for example, didn’t have to change form.
