Another chance to see The Royal Institution, London Annual Lectures to Young People by Geoffrey Gouriet, Chief Engineer, BBC Research and Development
Nowadays, when we listen to the radio, not only do we understand the words but we can identify the person speaking. Not only do we recognise the tune, but we enjoy the quality. Geoffrey Gouriet shows how this has been achieved.
(Lecture 4: Sunday 19 August: first shown on BBC2)
