Professor Jim Al-Khalili investigates the most accurate and yet perplexing scientific theory ever - quantum physics. At the beginning of the 20th century scientists were led into the hidden workings of matter, into the sub-atomic building blocks of the world around us. They discovered phenomena unlike any encountered before - a realm where things can be in many places at once, where chance and probability call the shots and where reality appears to only truly exist when we observe it. Albert Einstein hated the idea that nature, at its most fundamental level, is governed by chance. Jim reveals how, in the 1930s, Einstein thought he'd found a fatal flaw in quantum physics because it implies that sub-atomic particles can communicate faster than light in defiance of the theory of relativity. In the 1960s the scientist John Bell showed there was a way to test if Einstein was right and quantum mechanics was actually mistaken. Jim repeats this critical experiment - with shocking results.

Japan's landscapes range from snowy mountains to subtropical warmth. They are full of wildlife - and animals' and people's lives often cross as they adapt to these extremes. The central island of Honshu is home to over 100 million people, and its biggest city, Tokyo, is one of the largest urban metropolises on earth. But it has a wild heart - most of Honshu is mountainous. This wilderness is home to an astonishing range of wildlife - black bears, monkeys, exquisite fireflies and even cow demons. But all across this island, from the mountains to the edge of the sea, people and nature are drawn together in the most unexpected ways.

Ant colonies are one of the wonders of nature - complex, organised and mysterious. This programme reveals the secret, underground world of the ant colony in a way that's never been seen before. At its heart is a massive, full-scale ant nest, specially designed and built to allow cameras to see its inner workings. The nest is a new home for a million-strong colony of leafcutter ants from Trinidad. For a month, entomologist Dr George McGavin and leafcutter expert Professor Adam Hart capture every aspect of the life of the colony, using time-lapse cameras, microscopes, microphones and radio tracking technology.

An elegantly filmed documentary, Planet Ocean takes us on a beautiful adventure into the strangest domains of our planet - the oceans. The film features both the magnificence and the exposure of Earth's oceans. The dangers that threaten the whole planet also threaten us. We are guided through various series of events (sailfish relying on mackerel; mackerel relying on zooplankton; zooplankton relying on marine prairie) it is not simply to demonstrate the function of a food chain, but to illustrate the way in which all life is intrinsically interconnected. What happens to our oceans happens to our selves.

A global adventure of science and discovery--featuring the earliest dinosaurs of the Triassic Period to the monsters of the Cretaceous 'reincarnated' life-sized for the screen. Audiences will journey with some of the world's preeminent palaeontologists as they uncover evidence that the descendents of dinosaurs still walk (or fly) among us. From the exotic, trackless expanses and sand dunes of Mongolia's Gobi Desert to the dramatic sandstone buttes of New Mexico, the film will follow American Museum of Natural History palaeontologists as they explore some of the greatest dinosaur finds in history. Through the magic of scientifically accurate computer-generated animation, these newly discovered creatures, and some familiar favourites, will come alive... in a big way!

This stylish mix of documentary and historical epic chronicles the reign of Commodus, the emperor whose rule marked the beginning of Rome's fall. In the first episode, the death of Marcus Aurelius brings a century of Roman triumphs and victories to an end, transferring power to his spoiled, unprepared son Commodus. When his father bequeaths him the world's mightiest empire, he is forced to spill the blood of both friends and enemies alike to keep his crown.
