Another chance to see The Royal Institution, London Annual Lectures to Young People by Geoffrey Gouriet, Chief Engineer, BBC Research and Development
So far, Geoffrey Gouriet has shown electric signals can easily 'see' light and shade, but how much more difficult it must be to reproduce the subtleties of colour. He now demonstrates how electric signals can measure and transmit accurate colour pictures into our homes.
