Horizon meets the scientists working to make fatal car crashes a thing of the past.

Danny Wallace really wants a robot. He wants it to walk like him and talk like him. It's what scientists have been promising us for generations but it's a promise so far unfulfilled. Danny circumnavigates the globe searching for robot nirvana and trying to uncover how far away his dream is.

Miners, nuclear scientists, politicians, environmentalists and even the City have all wrestled for control of the national electricity grid and the power that it has brought.

At the heart of Britain sits something so all pervasive we don't even notice it's there - the national electricity grid. This three-part series charts how our lives got wired and the impact electrification has had.

Gustavo is a young Havana Communist who believes in the revolution; he hopes for a scholarship to study aeronautical engineering in Prague...

Adam Hart-Davis dons his hard hat and waders as he wanders through Belfast's sewer network to see how today's engineers are modernising the Victorian sewerage network with robots and ultra violet light.

Neil MacGregor visits Strasbourg, now in France, but also a city with a key place in German history, culture and precision engineering, as revealed by a model of the cathedral clock, now in the British Museum.

Melvyn Bragg and guests discuss the implications of the developments in genetic engineering. With Grahame Bulfield, geneticist, honorary professor, Edinburgh University and Director of the Roslin Institute, Edinburgh; Bryan Appleyard, features writer for The Sunday Times and author of Brave New Worlds: Genetics and the Human Experience.

Nanotechnology has become a big buzzword – so much so that the stockbrokers Merrill Lynch has created an index to track investment in the newly burgeoning industry. But others are concerned. Prince Charles, taking a lead from the environmental group ETC, has expressed concerns where this ‘atomtech’ may lead. The environmentalists see it as a step beyond genetic engineering.

The environmentalist ETC group has warned that nanotechnology (or ‘atomtech’ as they describe it) poses “horrendous social and environmental risks”. It was that group's report, The Big Down, which prompted the Prince of Wales to ask the Royal Society to look into the impacts of nanotechnology.

To most of us, viruses are the cause of illnesses like flu and measles. But to Angela Belcher of MIT, they’re the ideal building blocks for creating new materials at close to the atomic scale, in the new science of nanotechnology.

When I returned to this Engineering Department from the USA in 1984 my wife and I bought an historic and wonderful house some ten miles south of Cambridge. It was built around 1520, a date that could be substantiated to within a decade by the form of the oak beams that comprised its floors and ceilings. These had been shaped by iron blades that only lasted about ten years. Being someone of the present rather than the past I had not previously been much preoccupied with history but living in the splendid oak structure - like a fine sailing vessel that had gone aground - inspired me to wonder what had preoccupied the technologists and scientists of that age...

Since time immemorial people have been entranced by structures of great size. From the Colossus of Rhodes and the Great Pyramid, themselves no mean technical achievements, to the mighty Cunard 'Queens' built here in Glasgow, and whichever is transiently the tallest building in the world, beholders have gaped at the gigantic. One simple attraction has been that of comparative scale, so many times the size of a man or a horse or of Nelson's column, as popular illustrations used to show. It was easy for the bystander immediately to apprehend the vast size of these objects...

Almost exactly 93 years ago tonight, on 15 April 1912, over two thousand terrified and bewildered people found themselves with little warning drifting or drowning in the ice-cold North Atlantic. Only 712 of them survived that night. They were, of course, the passengers, officers, and crew of the White Star steamship Titanic, and they were in a sense victims of 'failures' of technology…
