Without us noticing, modern life has been taken over. Algorithms run everything from search engines on the internet to satnavs and credit card data security - they even help us travel the world, find love and save lives. Professor Marcus du Sautoy demystifies the hidden world of algorithms. By showing us some of the algorithms most essential to our lives, he reveals where these 2,000-year-old problem solvers came from, how they work, what they have achieved and how they are now so advanced they can even programme themselves.

The series Warrior Graveyard uncovers some extraordinary warrior skeletons from history. Archaeologists and forensic scientists use remains to tell the story of famous warriors of the past and unleash the full force of modern forensics upon them: battle scars, bone deformations and recoverable scraps of DNA will all be tested and explored. CGI and drama will then bring them dramatically to life, revealing a revolutionary new picture of how these warriors lived - and died.
An archaeological and forensic examination of six crusaders' bones brings to life the 1179 Battle of Jacob's Ford, revealing the wounds that killed the warriors in the Holy Land. With every sword slash comes an insight into an historic day. Excavations along the Israel/ Jordan border are unearthing skeletons and rewriting the history of the First Crusade. The site at Jacob's Ford is the only known Crusader battle site with complete skeletons. To secure the road between Akkon and Damascus, King Baldwin IV of Jerusalem had a mighty castle built at the Jacob's Ford of the Jordan River in October 1178. The fortress was a thorn in the side of Sultan Saladin, so he had it stormed a year later, before it was completed.
Excavations have been taking place on the site of the legendary crusader castle since the early 1990s. Archaeologists and forensic experts have examined the remains of six fallen crusaders and uncovered fascinating details about the Battle of Chastellet. The programme has secured access to the excavation and remains of some of the 80 Crusader Knights and 750 foot soldiers stationed at the fort when it was attacked and its Crusaders massacred by Saladin's army in 1179, in the battle that changed the course of history in the Middle East.

90% of the goods we consume in the West are manufactured in far-off lands and brought to us by ship. The cargo shipping industry holds the key to our economy, our environment and the very model of our civilization; without it, it would be impossible to fulfill the ever-increasing demands of our societies. Yet the functioning and regulations of this business remain largely obscure to many, and its hidden costs affect us all. Due to their size, freight ships no longer fit in traditional city harbors; they have moved out of the public's eye, behind barriers and checkpoints.
The film answers questions such as: Who pulls the strings in this multi-billion dollar business? To what extent does the industry control our policymakers? How does it affect the environment above and below the water-line? And what's life like for modern seafarers? Taking us on a journey overseas and oceans, we reveal in an audacious investigation the many faces of world-wide freight shipping and sheds light on the consequences of an all-but-visible industry.
