Professor Robert Bartlett explores how the Normans developed from a band of marauding Vikings into the formidable warriors who conquered England in 1066. He tells how the Normans established their new province of Normandy -'land of the northmen' - in northern France. Under the leadership of Duke William, they conquered England. The Battle of Hastings marked the end of the Anglo-Saxon aristocracy and monarchy. The culture and politics of England would now be transformed by the Normans.

Super quick computers and advanced mathematical formulas have taken over trading on the financial markets from human beings -algorithms- which seem to have a life of their own. The only ones who understand the system in any way are its architects, the algorithm developers. Haim Bodek is one such algo-developer. After finding some strange wrongdoings he set out on a personal crusade against this elusive system". The machinery behind our financial markets, consisting of mathematical models, data centers and miles and miles of fiber optic cables, is disguised by technological complexity and secrecy. The builders of this financial system are a new breed of Wall Street employees -quants- mathematicians and physicists who are responsible for a technological revolution. Haim Bodek is a quant; he specialized in artificial intelligence and worked for Goldman Sachs. He knows the system from the inside, he helped build it. Haim Bodek was invited to tell his story at the "Battle of the Quants" - a recurring event where quants discuss high-frequency trading, amongst other things. Bodek wrote an algorithm for trading machines that would generate guaranteed income - a money machine that weathered the financial meltdown of 2008. But then from one day to the next the algorithm stopped working.

Alex Winter explores the downloading revolution; the kids that created it, the bands and the businesses that were affected by it, and its impact on the world at large. He focuses on the advent of digital media sharing, including the rise of game-changing company Napster and controversial pioneers Shawn Fanning and Sean Parker. The digital revolution ultimately created a technology paradigm shift and upended the music industry. Audiences will hear insight from well known music artists and figures within the music industry including: The Beastie Boys' Mike D, Noel Gallagher, Henry Rollins, former Sony Music Chairman, Don Ienner, former record producer and Island Records founder Chris Blackwell and Hilary Rosen, former CEO of the Recording Industry Association of America.

Andrew Graham-Dixon begins his exploration of German art by looking at the rich and often neglected art of the German middle ages and Renaissance. He visits the towering cathedral of Cologne, a place which encapsulates the varied and often contradictory character of German art. In Munch he gets to grips with the earliest paintings of the Northern Renaissance, the woodcuts of Albrecht Durer and the cosmic visions of the painter Albrecht Altdorfer. Andrew also embarks on a tour of the Bavarian countryside, discovering some of the little-known treasures of German limewood sculpture.

Professor Brian Cox takes on the story of the force that sculpts the entire universe - gravity. Gravity seems so familiar, and yet it is one of the strangest and most surprising forces in the universe. Starting with a zero gravity flight, Brian experiences the feeling of total weightlessness, and considers how much of an effect gravity has had on the world around us. But gravity also acts over much greater distances. It is the great orchestrator of the cosmos. It dictates our orbit around the sun, our relationship with the other planets in our solar system, and even the way in which our solar system orbits our galaxy. Yet the paradox of gravity is that it is actually a relatively weak force. Brian takes a face distorting trip in a centrifuge to explain how it is that gravity achieves its great power, before looking at the role it plays in one of the most extraordinary phenomena in the universe - a neutron star. Although it is just a few kilometres across, it is so dense that its gravity is 100, 000 million times as strong as on Earth. Over the centuries our quest to understand gravity has allowed us to understand some of the true wonders of the universe, and Brian reveals that it is scientists' continuing search for answers that inspires his own sense of wonder.

In 1995, during the making of his TV series Triumph of the Nerds about the birth of the PC, Bob Cringely did a memorable hour-long interview with Steve Jobs. It was 10 years since Jobs had left Apple following a bruising struggle with John Sculley, the CEO he had brought into the company. At the time of the interview Jobs was running NeXT, the niche computer company he had founded after leaving Apple. During the interview, Jobs was at his charismatic best - witty, outspoken, visionary. In the end, only a part of the interview was used in the series and the rest was thought lost. But recently a VHS copy was found in the series director's garage. Now, cleaned up with modern technology, and put into context by Cringely.
