This year's Reith Lecturer is the distinguished engineer, Lord Broers. Alec Broers is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee. In his fifth and final lecture, Lord Broers explores the responsibilities of the technologist and questions their role in society. Who regulates technology? Is it up to the individual technologist or for companies, or governments to decide? He also examines the areas where we are likely to see the most significant advances in the next decades, and asks: who will be the winners in the race to develop future technologies?

He believes it has captured the public's imagination and given rise to the full range of emotions from admiration to fear. He explores the origins of nanotechnology with its roots in electronics and uses the relationship between it and nanoscience to illustrate the more general relationship between science and technology.

This year's Reith Lecturer is the distinguished engineer, Lord Broers. He is President of the Royal Academy of Engineering and Chairman of the House of Lords Science and Technology Committee.In his third Reith lecture Lord Broers argues that profound changes have taken place in the development of ideas and their translation in to the market place. This innovation revolution demands a new approach to research and product development. Some argue that technology threatens our way of life and must be controlled through regulation, however, Lord Broers believes that this is rarely necessary. He argues that it is better to allow the market - and the customers - to decide whether technologies succeed or not.
